Referring to FIG. 1 to FIG. 3, a lamp 100 of the embodiment includes a first lamp unit 110 and at least one second lamp unit 120 (one second lamp unit 120 is shown, for example). The first lamp unit 110 has a first connection portion 110a. The second lamp unit 120 has a second connection portion 120a. The first lamp unit 110 and the second lamp unit 120 are adapted to be stacked each other by the first connection portion 110a and the second connection portion 120a as shown in FIG. 1.
Referring to FIG. 3 to FIG. 5, particularly, the first connection portion 110a has a first electrode set 112, the second connection portion 120a has a second electrode set 122, and the first electrode set 112 and the second electrode set 122 contact each other as shown in FIG. 5 when the first lamp unit 110 and the second lamp unit 120 are stacked each other.
In the embodiment, the first lamp unit 110 further has a power cord 114 and is adapted to receive an electric power provided by an external power source through the power cord 114. The first lamp unit 110 is adapted to transmit the electric power to the second lamp unit 120 through the first electrode set 112 and the second electrode set 122. The second lamp unit 120 further has an electric power storage unit 124 as shown in FIG. 1.

The electric power storage unit 124 is, for example, a charge battery. The first lamp unit 110 and the second lamp unit 120 are adapted to store the electric power in the electric power storage unit 124.
According to the above configuration, the first lamp unit 110 and the second lamp unit 120 are adapted to be stacked together based on user's demand. Therefore, the first lamp unit 110 and the second lamp unit 120 having different light emitting colors, different light emitting intensities and/or different light emitting directions are stacked together to make the scene light of the lamp more variable, so as to provide users more pleasant and high quality scene light experiences.
Referring to FIG. 1, the first connection portion 110a and the second connection portion 120a further has a first magnetic component 116 and a second magnetic component 126 respectively. The first magnetic component 116 and the second magnetic component 126 are, for example, permanent magnets, and the first lamp unit 110 and the second lamp unit 120 are fixed together by magnetic attraction generated between the first magnetic component 116 and the second magnetic component 126.
Referring to FIG. 6 and FIG. 7, in this embodiment, the lamp 100′ includes a plurality of second lamp units 120 (two second lamp units 120 are shown in FIG. 6 for example). Each of the second lamp units 120 further has a third connection portion 120b, and each second connection portion 120a and each third connection portion 120b are disposed at two opposite sides of each of the second lamp units 120. The third connection portion 120b has a third electrode set 127 and a third magnetic component 128. When the second lamp units 120 are sequentially stacked on the first lamp unit 110 as shown in FIG. 6, two of the second lamp units 120 adjacent to each other are stacked together by magnetic attraction generated between the corresponding second magnetic component 126 and the corresponding third magnetic component 128, and two of the second lamp units 120 adjacent to each other contact each other by the corresponding second electrode set 122 having a third electrode 122a and a fourth electrode 122b and the corresponding third electrode set 127 having electrodes 127a and 127b respectively corresponding to the third electrode 122a and the fourth electrode 122a for electric power transmission. In other embodiments, the lamp may include three, four or more second lamp units sequentially stacked on the first lamp unit, and the invention is not limited thereto.
Referring to FIG. 8, the second lamp unit 120 is adapted to be stacked to an object 50 as shown in FIG. 8 by magnetic attraction generated between the second magnetic component 126 and the object 50 in the embodiment. In addition, the first lamp unit 110 shown in FIG. 1 has a fourth magnetic component 118, and the first lamp unit 110 is also adapted to be stacked to the object 50 by magnetic attraction generated between the fourth magnetic component 118 and the object 50 in the other embodiment. The object 50 is, for example, a metal plate, a magnetic plate, or other suitable structure.
Referring to FIG. 2 and FIG. 4, in the embodiment, the first connection portion 110a further has a position-limiting concave portion C, the first electrode set 112 is located in the position-limiting concave portion C. When the first lamp unit 110 and the second lamp unit 120 are stacked each other as shown in FIG. 1, the second connection portion 120a is limited in the position-limiting concave portion C, so as to further fix the second lamp unit 120 on the first lamp unit 110.
In the embodiment, when the first lamp unit 110 and the second lamp unit 120 are stacked each other as shown in FIG. 1, the first lamp unit 110 and the second lamp unit 120 are adapted to rotate relatively along a rotating axis A. When the first lamp unit 110 and the second lamp unit 120 stacked each other rotate relatively along the rotating axis A, a light emitting direction of the second lamp unit 120 is changed relative to a light emitting direction of the first lamp unit 110, so as to further make the scene light of the lamp 100 more variable. Similarly, in the other embodiment, the adjacent second lamp units 120 in FIG. 6 are also adapted to rotate relatively to change relative light emitting directions thereof.
Referring to FIG. 3 to FIG. 5, particularly, the first electrode set 112 includes a first electrode 112a and a second electrode 112b, and the second electrode set 122 includes the third electrode 122a and the fourth electrode 122b. The first electrode 112a and the second electrode 112b are, for example, anode and cathode respectively. The third electrode 122a and the fourth electrode 122b are, for example, anode and cathode respectively.
In the embodiment, in FIGS. 1-5, the first connection portion 110a of the first lamp unit 110 further has a ring-shaped trough T, and the second electrode 112b is a ring-shaped electrode and is located in the ring-shaped trough T. When the first lamp unit 110 and the second lamp unit 120 are stacked each other and relatively rotate along the rotating axis A, the first electrode 112a and the third electrode 122a are located on the rotating axis A and contact each other continuously, and the fourth electrode 122b inserts into the ring-shaped trough T and moves along and continuously contact the ring-shaped electrode (the second electrode 112b) with a relative rotation of the first lamp unit 110 and the second lamp unit 120. Similarly, in the other embodiment, in FIGS. 6-7, the third connection portion 120b of the second lamp unit 120 further has a ring-shaped trough T, and the electrode 127b of the third electrode set 127 is a ring-shaped electrode and is located in the ring-shaped trough T. When second lamp units 120 are stacked each other and relatively rotate, the electrode 127a and the third electrode 122a are located on the rotating axis and contact each other continuously, and the fourth electrode 122b inserts into the ring-shaped trough T and moves along and continuously contacts the ring-shaped electrode (the electrode 127b) with the relative rotation(s) of second lamp units 120.
Referring to FIG. 3 and FIG. 9, the second connection portion 120a further has at least one pillar P (three pillars P are shown in FIG. 3 for example). When the first lamp unit 110 and the second lamp unit 120 are stacked each other, each pillar P inserts into the ring-shaped trough T and props the ring-shaped electrode (the second electrode 112b), and each pillar P is adapted to move along the ring-shaped trough T with the relative rotation of the first lamp unit 110 and the second lamp unit 120. By the pillars P propping the second electrode 112b, contact force between the second electrode 112b and the fourth electrode 122b may be decreased, so as to lower friction between the second electrode 112b and the fourth electrode 122b contacting each other and moving relatively. Similarly, in the other embodiment, for stacked second lamp units 120, the corresponding second connection portion 120a with the pillar(s) P inserting into the corresponding ring-shaped trough T and propping the corresponding ring-shaped electrode 127b of the third electrode set (127 shown in FIG. 7 for example) may also be utilized to decrease the contact force between two adjacent second lamp units 120.
In the embodiment of FIG. 10, the configuration and operation of the first connection portion 110a′, the second connection portion 120a′, and the second electrode 112b′ are similar to the configuration and operation of the first connection portion 110a, the second connection portion 120a, and the second electrode 112b in FIG. 5. The difference between FIG. 10 and FIG. 5 is that, the fourth electrode 122b′ includes an elastic portion S1 and a contacting portion S2 connected to each other, and the contacting portion S2 is adapted to lean against the ring-shaped electrode (the second electrode 112b′) by elastic force of the elastic portion S1, such that the fourth electrode 122b′ may contact the second electrode 112b′ tightly for increasing the stability between the first lamp unit 110 and the second lamp unit 120. Similarly, in the other embodiment, two adjacent stacked second lamp units 120 may also utilize the contact relation between the corresponding fourth electrode (122b shown in FIG. 7 for example) having the elastic portion S1 and a contacting portion S2 of the second electrode set (122 shown in FIG. 7 for example) and the corresponding electrode 127b of the third electrode set (127 shown in FIG. 7 for example) to tightly contact each other to further achieve the increased stability.
Referring to FIG. 2, in the embodiment, the first lamp unit 110 includes a main body 111, a cover 113, and a light source 115. The main body 111 has a front side 111a and a rear side 111b opposite to each other. The cover 113 coves the main body 111. The light source 115 is, for example, a light emitting diode (LED) light source and disposed at the front side 111a. A light emitted by the light source 115 passes through the cover 113 to reach external space. In the embodiment, the light emitting intensity at the front side 111a is substantially higher than the light emitting intensity at the rear side 111b. In another embodiment, the cover 113 is, for example, a diffuser, and the light is diffused from the front side 111a to the rear side 111b by the cover 113, such that the light emitted by the light source 115 is substantially uniform around the first lamp unit 110. In the other embodiment, the cover 113 is, for example, a semi-transparent cover, and the light may not be sharp to achieve the smoother scene effect.
Referring to FIG. 11, in the first lamp unit 210 of FIG. 11, the configuration and operation of the first connection portion 210a, the main body 211, the light source 215 and the power cord 214 are similar to the configuration and operation of the first connection portion 110a, the main body 111, the light source 115 and the power cord 114 in FIG. 2. The difference between FIG. 11 and FIG. 2 is that, the cover 213 includes a light penetration portion 213a corresponding to the front side 211a of the main body 211 and a light shielding portion 213b corresponding to the rear side 211b of the main body 211. Therefore, the light emitted by the light source 215 will not reach external space through the rear portion of the cover 213.
Similarly, the above-mentioned second lamp unit 120 includes a main body, a cover, and a light source, and the configuration and operation thereof are similar to the configuration and operation of the main body 111, the cover 113, and light source 115 in FIG. 2 or the configuration and operation of the main body 211, the cover 213, and light source 215 in FIG. 11, a relevant description thereof is not repeated herein.
Referring to FIG. 1, in the embodiment, the first lamp unit 110 further has a wireless transmission module 119, and an external device (for example, a smart phone, tablet computer, notebook or PC, and etc) is adapted to transmit a wireless signal to the wireless transmission module 119 to control a light emitting color and/or a light emitting intensity of the first lamp unit 110. Similarly, the second lamp unit 120 further has a wireless transmission module 129, and the external device is adapted to transmit a wireless signal to the wireless transmission module 129 to control a light emitting color and/or a light emitting intensity of the second lamp unit 120. The wireless transmission module 119 and the wireless transmission module 129 are, for example, Bluetooth module or other type of wireless transmission module, and the invention is not limited thereto.
In summary, in the embodiment of the invention, the lamp units of the lamp are adapted to be stacked together based on user's demand. Therefore, the lamp units having different light emitting colors, different light emitting intensities and/or different light emitting directions are stacked together to make the scene light of the lamp more variable, so as to provide users more pleasant and high quality scene light experiences. In addition, in the embodiment of the invention, when the lamp units are stacked together, the lamp units are adapted to rotate relatively, so as to further make the scene light of the lamp more variable. Further, in the embodiment of the invention, the lamp units may include magnetic components and be stacked together by magnetic attraction generated between the magnetic components, such that each lamp unit is prevented from being separated from other lamp units unexpectedly.
