As shown in
During working, the solar panel 5 receives solar light that transmits through the lampshade 2, and converts radiation energy in the solar light into electric energy to be stored in the power unit, which supplies power to the light source 3, thereby ensuring the normal operation of the light source. Meanwhile, a plurality of light guide elements 21 are designed to guide the light, which improves a light illumination effect and increases the utilization rate of the light source and the ornamental value.
In such a way, the above specific design allows the solar lamp to ensure sufficient power as compared with a traditional lamp. Specifically, the solar lamp can convert the solar radiation energy into the electric energy through the solar panel in the day time to charge the power unit, which continuously keeps sufficient power for the power unit to avoid the problem that the light source does not work due to insufficient power, therefore, the step of replacing a power battery is omitted. Furthermore, the ornamental value of the lamp is effectively increased by arranging a plurality of light guide elements 2 on the lampshade to guide the light emitted by the light source 3.
Preferably, the base 1 and the lampshade 2 are both circular, and the light guide elements 2 are arranged at interval along an outer edge of the lampshade and are annular. Further, the light guide elements 2 are petal-shaped, such that the whole lamp looks like a flower (sunflower). Therefore, the ornamental value of the lamp is greatly increased regardless of a turning-on state at night or an idle state in the day. With doubt, the lampshade and the light guide elements may also have other shapes to form various suitable decorations for people to enjoy their beauty.
In general, a solar lamp according to this embodiment is for use in outdoor regions with sufficient sunlight.
Further, the power unit includes a circuit board 41 and an accumulator battery 42 electrically connected to the circuit board 41, and said solar panel 5 is electrically connected to the circuit board 41. It can be understood that the solar lamp supplies power to the light source by using the accumulator battery at night, and charges the accumulator battery by converting the solar radiation energy into the electric energy via the solar panel in the day with sufficient sunlight.
Specifically, the light source 3 includes a plurality of LED beads, which are annularly arranged on the circuit board 41 at interval.
Further, the lampshade 2 is provided with lenses 22 at positions corresponding to the LED beads; and the lenses 22 are convexly semi-spherical. Hence, when the LED beads work, the light emitted by the LED beads irradiate inside faces of the lenses, which enlarges a light illumination area of the LED beads and changes the light illumination directions of the LED beads, thereby enhancing the illuminating capacity of the lamp.
Preferably, the lampshade 2 is fixed on the base 1 by means of ultrasonic welding, and the lamp 2 and the base 1 are sealed to increase the waterproofness, such that the invention can work stably in rainy days. Without doubt, the lampshade 2 and the base 1 may also be mounted by other means, and a rubber ring is disposed between the lampshade 2 and the base 1 to increase airtightness and waterproofness, such that the invention is applicable in water.
Specifically, the support element 6 is further disposed, which is detachably connected to the underside of the base 1. When used outdoors, the lamp can be fixed by inserting the support element 6 into earth floor. Specifically, the support element 6 includes an upper segment 61 and a lower segment 62, which are detachably connected. The upper segment 61 and the lower segment 62 are rod-like; the upper segment 61 is pivotably provided with a connecting element 63; a slot 11 allowing the insertion of the connecting element 63 is disposed at the bottom of the base 1; and the upper segment 61 is detachably mounted at the bottom of the base 1 by the cooperation of the connecting element 63 and the slot 11. In such way, the base 1 is rotatably adjustable with respect to the upper segment 61. That is, the illuminating angle of the lamp is adjustable. It should be noted that the upper segment 61 and the lower segment 62 may be disposed based on the willingness and choice of a user. If a higher height is needed, the upper segment and the lower segment may be used together; and if a lower height is needed, the lower segment may be removed, with the upper segment inserted into the earth floor only.
Preferably, the connecting element 63 is further provided with a limiting portion 631; the slot 11 is provided with a limiting groove 111 at a position corresponding to the limiting portion 631. The rotation between the base 1 and the connecting element 63 is limited by the cooperation of the limiting portion 631 and the limiting groove 111, thereby achieving a positioning effect.
Specifically, the upper segment 61 is provided with a convex drum position 611; the drum position 611 and the upper segment 61 may be of an integrally formed structure; or the drum position 611 is a sleeve element sleeved on the upper segment 61. When the lamp is inserted into the earth floor through the support element, a stress surface of the upper segment 61 may be enlarged by the drum position 611 to increase the stress tolerance of the upper segment 61.
It should be added that in order to better adjust the length of the support element 6, several connecting rods may be further disposed between the upper segment 61 and the lower segment 62; both ends of each of the several connecting rods are detachably connected with the upper segment 61 and the lower segment 62 respectively by a buckle structure or by other structures. A user may accordingly add the connecting rods of a proper length between the upper segment 61 and the lower segment 62 to increase the overall length of the support element 6, thereby adjusting the height position of the lamp after the support element 6 is inserted into the earth floor.
Specifically, the base 1 is further provided with a power interface 7, which is electrically connected to the power unit and may be configured to supply power to other external lamps, thereby connecting several lamps in series. Further, the base 1 is also provided with a button switch 8 that is electrically connected to the power unit, and the button switch 8 is configured to control the on and off of the light source 3.
It should be noted that the invention may also control the on and off of the light source, the selection of a color of the light source, and an illumining mode of the light source by using a remote controller. This relates to the prior art, and its specific principle and connection will not be described in detail herein.
The design focus of the invention lies in that the solar lamp can ensure sufficient power and stable operation mainly by its specific design as compared with a traditional lamp; and furthermore, the plurality of light guide elements are disposed on the lampshade to guide light emitted by the light source, which effectively increases the ornamental value of the lamp and keeps in line with the aesthetic trend of people.
Then, the support element is disposed, and the solar lamp when rotating is connected to the support element, such that the solar lamp according to the invention can be adjusted in illuminating angle, thereby achieving convenience in use.
Moreover, the lampshade is provided with the lenses at the positions corresponding to the LED beads, such that the illuminating effect is further improved and the utilization rate of the LED beads is increased.
Described above are merely preferred embodiments of the invention, and are not intended to limit the technical scope of the invention in any forms. Therefore, any tiny modification, equivalent variation and the like that are made to the above embodiments based on the technical essence of the invention shall be still included within the scope of the technical solutions of the invention.
