In other words, in one embodiment, the number of an element can be one and in other embodiment the number of the element can be greater than one. The term “a” is not construed as a limitation of quantity.

Referring to FIGS. 1-3B, a lamp according to a first preferred embodiment of the present invention is disclosed and illustrated in the following description. The lamp has a surrounding lighting state and a side lighting state, wherein the lighting states of the lamp is configured to be switchable between the surrounding lighting state and the side lighting state, so as for the user to choose the lighting states of the lamp based on the needs. For example, when the lamp is utilized in camping, the lighting states of the lamp can be switched to the surrounding lighting state, such that the lamp can provide even and uniform light to the surrounding. When the lamp is utilized for illumination, the lighting states of the lamp can be switched into the side lighting state, such that the lamp only provides light to a specific direction.

Specifically, the lamp comprises a lamp body 10 and at least two illumination parts 20, wherein the lamp body 10 has an upper portion 101, a lower portion 102 corresponding to the upper portion 101, and at least two optical cavities 103 respectively extended between the upper portion 101 and the lower portion 102, wherein the illumination parts 20 are arranged in the optical cavities 103 respectively and adapted to independently illuminate in the optical cavities 103 respectively, so as to allow the lighting states of the lamp be controlled to switch between the surrounding lighting state and the side lighting state through controlling operating modes (e.g. if the illumination parts is lighted) of the illumination parts arranged in the optical cavities 103 respectively.

It is worth mentioning that the lamp body 10 of the lamp as illustrated in FIGS. 1-3B has two optical cavities 103, wherein each of the optical cavities 103 has at least one illumination part 20 provided therein. When the lamp is in the surrounding lighting state, the illumination parts 20 respectively arranged in the two optical cavities 103 of the lamp body 10 will both be powered and in an operating mode (the illumination parts 20 are lighted), so that the lamp 10 can provide light to the surrounding environment. Correspondingly, when the lamp is in the side lighting state, one of the illumination parts 20 in the respective optical cavity 103 of the lamp body 10 is powered and in a lighting state, while the illumination part 20 in the other optical cavity 103 of the lamp body 10 is not powered and is in an off state (the illumination part 20 is not lighted), so that the lamp body 10 is able to provide light toward a specific direction only. Preferably, the illumination widths of the two optical cavities 103 of the lamp body 10 are consistent. Optionally, the illumination widths of the two optical cavities 103 of the lamp body 10 are different, so that the specific mode of the lamp in the side lighting state can be selected. For instance, when the illumination part 20 in the optical cavity 103 having a wider illumination width of lamp body 10 are powered and in an operating mode, the lighting width of the lamp will be larger. Correspondingly, when the illumination part 20 in the optical cavity 103 having a smaller illumination width of the lamp body 10 is powered and in an operating mode, the lighting width of the lamp will be smaller.

It is worth mentioning that the arrangement of the lamp body 10 of the lamp, as illustrated in FIGS. 1-3B, has two optical cavities 103, simply as an example to aid the description and understanding of the lamp of the present invention rather than to limit the content and scope of the lamp of the present invention. For example, for the lamp according to other embodiments of the present invention, the quantity of the optical cavity 103 of the lamp body 10 may be three or more.

Referring to FIG. 1-3B, the lamp body 10 comprises a photopermeable surrounding wall 11 and a partition member 12, wherein the surrounding wall 11 has an accommodation space 111, wherein the partition member 12 is arranged in the accommodation space 111 of the surrounding wall 11, so as to utilize the partition member 12 to divide the accommodation space 111 of the surrounding wall 11 and to form and define at least two optical cavities 103 and to utilize the surrounding wall 11 to form and construct the exterior of the lamp body 10.

Preferably, the surrounding wall 11 is a circular surrounding wall, that is a circular cross section of the surrounding wall 11 defining a circular shape such that when the lamp is in the surrounding lighting state, the light generated by each of the illumination parts 20 in the optical cavities 103 can pass through the surrounding wall 11 to evenly and uniformly provide light to the surrounding all around. Optionally, the surrounding wall 11 may also be an oval shaped side wall, a polygonal shaped side wall, and etc.

Preferably, the partition member 12 of the lamp body 10 is an opaque partition member, so that the partition member 12 only allows the light generated by the illumination part 20 in one of the optical cavities 103 radiating to the outside through the surrounding wall 11 that forms the optical cavity 103 and prevent the light generated by the illumination part 20 in the other optical cavity 103 from passing through the partition member 12 and entering the other optical cavity 103.

The partition member 12 further comprises a spacer body 121 and at least two spacer boards 122, wherein the spacer body 121 is kept in the accommodation space 111 of the surrounding wall 11, wherein the spacer boards 122 are respectively extended between an outer wall of the spacer body 121 and an inner wall of the surrounding wall 11 in a spaced manner with respect to each other, and that the two ends of each of the spacer boards 122 and the spacer body 121 are respectively extended to the upper portion 101 and the lower portion 102 of the lamp body 10, so as to form and define the one or more optical cavities 103 between the surrounding wall 11 and the spacer body 121 and the adjacent spacer boards 122.

Preferably, referring to the lamp according to the preferred embodiment as illustrated in FIGS. 1-3B, each of the spacer boards 122 is respectively and integrally formed on the outer wall of the spacer body 121, wherein an outer edge of each of the spacer boards 122 is extended to and attached on the inner wall of the surrounding wall 11. The radian of the outer edges of the spacer boards 122 of the partition member 12 is consistent to the radian of the inner wall of the surrounding wall 11, so as to have the outer edges of the spacer boards 122 being closely attached on the inner wall of the surrounding wall 11. Therefore, when the illumination part 20 arranged in one of the two optical cavities 103 generates light, the spacer body 121 and the spacer boards 122 of the partition member 12 can block the light from entering the other one of the two optical cavities 103.

Optionally, for the lamp according to another preferred embodiment of the present invention, each of the spacer boards 122 is integrally formed on the inner wall of the surrounding wall 11, wherein the inner side of each of the spacer boards 122 is extended to and attached on the outer wall of the spacer body 121. The radian of the inner side wall of the spacer boards 122 of the partition member 12 is consistent to the radian of the outer wall of the spacer body 121, so as to have the inner side wall of the spacer boards 122 being closely attached on the outer wall of the spacer body 121. Therefore, when the illumination part 20 arranged in one of the optical cavities 103 generates light, the spacer body 121 and the spacer boards 122 of the partition member 12 can block the light from entering the other one of the optical cavities 103.

Optionally, for the lamp according to another preferred embodiment of the present invention, the spacer body 121, the spacer boards 122, and the surrounding wall 11 are independent to one another, so that the outer sides and the inner sides of the spacer boards 122 are respectively extended so as to have the outer edges of the two sides of the spacer boards 122 respectively being closely attached on the inner wall of the surrounding wall 11 and the outer wall of the spacer body 121. Therefore, when the illumination part 20 arranged in one of the optical cavities 103 generates light, the spacer body 121 and the spacer boards 122 of the partition member 12 can block the light from entering the other optical cavity 103. More specifically, the spacer body 121 has at least a locating groove and the surrounding wall 11 also has at least a locating groove, wherein the spacer boards 122 is extended between the spacer body 121 and the surrounding wall 11 in the manner that the inner side and the outer side of the spacer boards 122 are respectively positioned in the locating groove of the spacer body 121 and the locating groove of the surrounding wall 11.

Preferably, the spacer body 121 of the partition member 12 is retained in a middle portion of the accommodation space 111 of the surrounding wall 11, wherein the circular shape defined by the circular cross section of the spacer body 121 and the circular shape defined by the circular cross section of the surrounding wall 11 are concentric circles, such that when the lamp is in the surrounding lighting state, the lamp is able to provide even and uniform light to the surrounding.

It is understandable that, by extending the spacer boards 122 between the spacer body 121 and the surrounding wall 11, the lamp reinforces the strength of the surrounding wall 11 of the lamp through the spacer boards 122 that avoids the surrounding wall 11 from undesirable tendencies like distortion.

Referring to FIGS. 1-3B, the lamp body 10 further comprises an upper cover body 13 and a lower cover body 14, wherein the upper cover body 13 is arranged on the upper portion 101 of the lamp body 10, so as for closing the upper openings of the optical cavities 103. Correspondingly, the lower cover body 14 is arranged on the lower portion 102 of the lamp body 10 for closing the lower openings of the optical cavities 103, so that each of the optical cavities 103 respectively becomes a closed chamber. Preferably, the partition member 12 and the lower cover body 14 are integrally formed, so that when the partition member 12 is arranged in the accommodation space 111 of the surrounding wall 11 to form and define the optical cavities 103 between the partition member 12 and the surrounding wall 11, the lower cover body 14 closes the lower openings of the optical cavities 103. Optionally, the surrounding wall 11 and the upper cover body 13 are integrally formed, so that when the partition member 12 is arranged in the accommodation space 111 of the surrounding wall 11 to form and define the optical cavities 103 between the partition member 12 and the surrounding wall 11, the upper cover body 13 closes the upper openings of the optical cavities 103.

Further, referring to FIGS. 1-3B, the lamp comprises a circuit board 30, wherein the illumination parts 20 are arranged on the circuit board 30, wherein the circuit board 30 is arranged on the upper portion 101 of the lamp body 10 in such a manner that the circuit board 30 closes the upper opening of the optical cavities 103. Besides, the circuit board 30 allows the illumination parts 20 to be respectively arranged in the optical cavities by being held in the optical cavities 103, so that the lights generated by the illumination parts 20 can pass through the surrounding wall 11 and radiate to the outside of the lamp. When assembling the lamp, after the circuit board 30 is arranged on the upper portion 101 of the lamp body 10, the upper cover body 13 is mounted on the lamp body 10, so as to prevent the circuit board 30 from being revealed and exposed. Preferably, the illumination parts 20 may be LED luminous elements or LED luminous component units being attached and mounted on the circuit board 30.

Preferably, at least one of the spacer boards 122 of the partition member 12 is extended upwardly to form a positioning bulge 1221. Correspondingly, the circuit board 30 has at least a positioning notch 31. When the circuit board 30 is arranged on the upper portion 101 of the lamp body 10, the positioning bulge 1221 of the spacer boards 122 is kept in the positioning notch 31 of the circuit board 30, so as to ensure the illumination parts 20 arranged on the circuit board 30 to be positioned and arranged at the upper ends of the optical cavities 103 respectively for arranging the illumination parts 20 in the optical cavities 103 respectively, that avoids dislocations of the illumination parts 20 and the optical cavities 103.

The lamp in the insect repellent state can provide a function of insect repelling, while the lamp in the illumination state can mainly provide a function of illumination.

The lamp has a surrounding service mode and a side service mode, and that the illumination state of the lamp is arranged to be switchable between a surrounding lighting state and a side lighting state so as for the user to choose the service mode of the lamp based on the user's needs. Specifically, in the surrounding service mode, the lamp radiates light to the surrounding, while in the side service mode the lamp radiates light to one side only, that is at least a portion of the surrounding of the lamp is not radiated with light.

When the lamp is in the insect repellent state, the lamp can also be in the surrounding service mode or the side service mode. In other words, when the lamp is able to generate light and repel insects, the lamp is able to radiate light all around or to radiate light toward the predetermined side(s).

When the lamp is in the illumination state, the lamp can be in the surrounding service mode or the side service mode. In other words, when the lamp is able to generate light for illumination, the lamp is able to radiate light all around or to radiate light toward the predetermined side(s).

In particular, the lamp comprises a lamp body 10B, at least an illumination part 20B, and at least an insect repellent part 30B, wherein the illumination part 20B and the insect repellent part 30B are respectively mounted on the lamp body 10B.

The lamp body 10B has at least an optical cavity 100B. According to an embodiment that the lamp body 10B only has one optical cavity 100B, the illumination part 20B and the insect repellent part 30B are arranged in the same optical cavity 100B.

Correspondingly, according to an embodiment that the lamp body 10B has two or more optical cavities 100B, the illumination part 20B and the insect repellent part 30B may be arranged in the same optical cavity 100B or be respectively arranged in different optical cavities 100B. The lamp body 10B has an upper portion 101B and a lower portion 102B, wherein the position of the upper portion 101B is higher than the position of the lower portion 102B. The optical cavities 100B are configured to be extended from the upper portion 101B to the lower portion 102B.

According to this third preferred embodiment of the present invention, the quantity of the optical cavity 100B of the lamp body 10B is embodied to be two. Besides, the two optical cavities are arranged in a back-to-back manner. When the lamp is hung and utilized, the light radiated from one of the optical cavities 100B of the lamp body 10B is projected towards one side, while the light radiated from the other optical cavities 100B of the lamp body 10B is projected towards the other side.

For example, one illumination part 20B is arranged in one of the optical cavities 100B of the lamp body 10B and one insect repellent part 30B is arranged in another one of the optical cavities 100B of the lamp body 10B, wherein when the illumination part 20B is powered to function, the corresponding optical cavity 100B of the lamp body 10B can produce light radiating outwards, and correspondingly, when the insect repellent part 30B is powered to repel insects, the corresponding optical cavity 100B of the lamp body 10B can produce light radiating outwards.

It is worth noted that the insect repellent part 30B can be embodied as a light source capable of radiating light of specific frequency. For example, the light generated by the insect repellent part 30B may be yellow light which is a light with invisible lights such as ultraviolet light, infrared light, and the like being filtered. Preferably, at least a portion of the light emitted by the insect repellent part 30B is visible light, so that when the lamp is functioning for insect repelling, it may also function for illumination.

When the illumination part 20B and the insect repellent part 30B are lighted up at the same time, the lamp is in the surrounding lighting state. The lamp can radiate lights all around and at least a portion of the light emitted by the lamp can be used for repelling insects.

When only the illumination parts 20B is lighted up, the lamp is in the side lighting state. The light emitted by the lamp is from one side and is capable of illuminating.

When only the insect repellent part 30B is lighted up, the lamp is in the side lighting state. The light emitted by the lamp is from one side and is capable of repelling insects. Of course, when the insect repellent light is a visible light, then the lamp may also serve for illuminating.

According to some other embodiments of the present invention, each of the optical cavities 100B of the lamp body 10B can be arranged to have one insect repellent part 30B and each of the optical cavities 100B can also be arranged to have one illumination part 20B. When the illumination part 20B and the insect repellent part 30B in the same optical cavity 100B of the lamp body 10B are both lighted, the lamp is capable of providing illumination of enough brightness and insect repellent function at the same time. When one optical cavity 100B of the two optical cavities 100B of the lamp body 10B is lighted, whether the illumination part 20B and/or the insect repellent part 30B is lighted, the lamp is in the side lighting state. When the two optical cavities 100B are both lighted up, whether it is the illumination part 20B and/or the insect repellent part 30B in one optical cavity 100B or the insect repellent part 30B and/or the illumination part 20B in the other optical cavity 100B, the lamp is in the surrounding lighting state.

Further, according to the present embodiment, when the lamp is in use when, for example, the user is able to sleep at night, the user may operate the lamp to switch it to the side service mode. Then the insect repellent part 30B of the lamp can still work on one side only for repelling insects. The insect repellent part 30B of the lamp may be arranged to be back to the user, so as to reduce the influence of the light emitted by the insect repellent part 30B to the sleep of the user as much as possible. In other words, the lamp is rotatable, so as to allow the insect repellent part 30B facing away from the user.

It is worth noting that, because the insect repellent part 30B may still produce light, therefore when the user wakes up at night and needs to find something in the dark, such as looking for a cellphone to tell the time, s/he can still rely on the light emitted by the insect repellent part 30B of the lamp to look for the object. Alternatively, the use may utilize the light emitted by the insect repellent part 30B of the lamp to find the lamp and then operate the lamp to light up the illumination part 20B of the lamp for illumination, so as for providing a stronger light for helping him/her in searching objects.

Further, when the lamp is hung outside of the tent, as illustrated in FIG. 12A, the illumination part 20B of the lamp can be arranged facing away from the tent so as for radiating light toward the user outside of the tent. The insect repellent part 30B of the lamp is capable of facing toward the tent so as for radiating light toward the tent. Because the light emitted by the insect repellent part 30B is weaker than the light emitted by the illumination part 20B, the light emitted by the insect repellent part 30B has less influence to the user in the tent.

When the lamp is placed and utilized in a tent, since some tents have screen window or screen door curtain, the insect repellent part 30B may still project its light outwards to repel the mosquitos outside the tent, as illustrated in FIG. 12B for example.

Furthermore, referring to FIGS. 8 and 9, the lamp comprises a dividing element 14B, wherein the dividing element 14B divides the space between the upper portion 101B and the lower portion 102B of the lamp body 10B into the at least two optical cavities 100B.

Each of the spacer boards 142B is connected with the spacer body 141B. The spacer body 141B is arranged between the spacer boards 142B.

The lamp body 10B comprises a circular photopermeable wall 11B, a top cover 12B, a bottom cover 13B, and the dividing element 14B. The optical cavities 100B of the lamp body 10B are formed and defined between the top cover 12B and the bottom cover 13B. The dividing element 14B is extended between the top cover 12B and the bottom cover 13B. The photopermeable wall 11B is extended between the top cover 12B and the bottom cover 13B. The photopermeable wall 11B is arranged to surround around the dividing element 14B. The light emitted by the illumination part 20B or the insect repellent part 30B is blocked by the dividing element 14B and is merely allowed to pass through the photopermeable wall 11B to be transmitted outwardly.

The top cover 12B and the bottom cover 13B respectively close the space formed and defined by the photopermeable wall 11B from a top end position and a lower end position of the photopermeable wall 11B. The photopermeable wall 11B forms and defines an accommodation chamber 110B, wherein an upper portion and a lower portion of the accommodation chamber 110B are respectively closed by the top cover 12B and the bottom cover 13B. When the illumination part 20B or the insect repellent part 30B radiates light in the accommodation chamber 110B, because the top end and the bottom end of the photopermeable wall 11B are respectively closed by the top cover 12B and the bottom cover 13B, the light can therefore be concentrated in the accommodation chamber 110B, while the light is avoided from leaking from the top or the bottom of the photopermeable wall 11B as much as possible.

Further, the lamp comprises a circuit board 40B, wherein the circuit board 40B is positioned above the photopermeable wall 11B to close the top of the photopermeable wall 11B and provide an opening there. According to the present embodiment, the top cover 12B is embodied as the circuit board 40B. The at least one illumination part 20B is mounted on the circuit board 40B.

The circuit board 40B faces toward the at least two optical cavities 100B, wherein at least one of the illumination parts 20B faces towards one of the optical cavities 100B, while at least one insect repellent part 30B faces toward the other one of the optical cavities 100B.

When the illumination part 20B or the insect repellent part 30B are lighted up, the light emitted by the illumination part 20B or the insect repellent part 30B radiates toward the position of the bottom cover 13B from the top to the bottom.

The bottom cover 13B forms a conical reflection wall 15B, wherein the reflection wall 15B is arranged to be oblique and formed through being extended downwardly and outwardly from the bottom end of the spacer body 141B of the dividing element 14B. When the light emitted by the illumination part 20B or the insect repellent part 30B radiates from the top downwardly to the reflection wall 15B of the bottom cover 13B, due to the reflection of the reflection wall 15B, the light is reflected by the reflection wall 15B to the photopermeable wall 11B to pass therethrough and outwardly transmit outside.

According to some other embodiments of the present invention, the illumination part 20B or the insect repellent part 30B may be mounted on the spacer body 141B or the spacer boards 142B of the dividing element 14B. The illumination part 20B or the insect repellent part 30B may radiate light outwardly along a horizontal direction.

According to some other embodiments of the present invention, the illumination part 20B or the insect repellent part 30B may be mounted on the bottom cover 13B. The illumination part 20B or the insect repellent part 30B may upwardly radiate light from the bottom to the top.

Person skilled in the art should understand that the above disclosures and illustrations are all examples for the arranging positions of the illumination part 20B and the insect repellent part 30B, but the arranging positions of the illumination part 20B and the insect repellent part 30B shall not be construed as limiting the scope of the claims of the present invention.

Further, the top ends of the spacer boards 142B of the dividing element 14B are tightly and closely attached on the circuit board 40 relatively, so as to minimize any light passing through the junction between the circuit board 40B and the top of the spacer boards 142B. The bottom end of the spacer boards 142B is fittingly and closely attached on the bottom cover 13B, so as to minimize any light passing through the junction between the bottom cover 13B and the bottom end of the spacer boards 142B.

Optionally, the spacer boards 142B and the bottom cover 13B are made integrally to form an integral body.

The side edges of the spacer boards 142B of the dividing element 14B are attached on the inner side of the photopermeable wall 11B, so as to reduce the interference of the light of the adjacent optical cavity 100B of the lamp body 10B. The shape of the photopermeable wall 11B may be, but not limited to, cylinder shape, circular cone shape, or stereoscopic shape.

Further, the lamp comprises a base 50B, a power supplying part 60B, and at least a conductive wire 70B, wherein the lamp body 10B is mounted on the base 50B. The power supplying part 60B is arranged on the base 50B. The base 50B can be stably supported on the bottom side of the lamp body 10B.

The connection wire 70B electrically links the power supplying part 60B and the circuit board 40B, so as for conducting electric power to the illumination part 20B or the insect repellent part 30B. It is worth noting that the illumination part 20B and the insect repellent part 30B may both be electrically linked with the same circuit board 40B or the illumination part 20B and the insect repellent part 30B may be electrically linked with different circuit boards 40B respectively.

The power supplying of the illumination part 20B and the insect repellent part 30B may share the same connection wire 70B or utilize different connection wires 70B.

The at least one connection wire 70B is extended from the power supplying part 60B of the base 50B at the bottom to the circuit board 40B at the top. In detail, the spacer body 141B of the dividing element 14B forms and defines a receiving chamber 1410B, wherein the receiving chamber 1410B is provided to be extended from the top to the bottom, wherein the at least one connection wire 70B passes through the bottom cover 13B of the lamp body 10B, then passes through the receiving chamber 1410B of the spacer body 141B of the dividing element 14B, and then extends to the position of the circuit board 40B.

In this way, the at least one connection wire 70B can be isolated relatively from the optical cavities 100B of the lamp body 10B. In other words, the at least one connection wire 70B passing through the lamp body 10B will not affect the illumination effect or the insect repelling effect of the lamp body 10B.

In detail, the base 50B comprises a base main body 51B, a battery cartridge body 52B and a battery cartridge cover 53B, wherein the battery cartridge body 52B and the battery cartridge cover 53B are supported on the base main body 51B.
