1. Field of the Invention
The present invention relates to a solar LED lamp assembly, and more particularly to a solar LED lamp assembly which utilizes a solar energy to drive an LED lamp.
2. Description of related art
LED lamp assemblies are highly energy efficient electrical light sources, and are increasingly being considered for indoor or outdoor lighting purposes. An LED lamp assembly comprises an LED lamp and an electric source for driving the LED lamp. When the LED lamp assembly works, an electrical energy is consumed. However, such LED lamp assembly cannot be used in some districts such as a district deep in the mountains where it is difficult to supply any electric power.
What is needed, therefore, is a solar LED lamp assembly which can overcome the above-mentioned disadvantages.
A solar LED lamp assembly includes a bracket, an LED lamp mounted on a bottom end of the bracket, a solar panel assembly slantwise mounted on a top end of the bracket and electronically connecting with the LED lamp, and a reflector sandwiched between the solar panel assembly and the top end of the bracket and oriented towards the LED lamp. The LED lamp includes a heat sink and a printed circuit board mounted with a plurality of LED modules thereon and received in the heat sink.
Other advantages and novel features of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
Many aspects of the present apparatus can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present apparatus. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
Referring to
The bracket 10 has a V-shaped configuration. The bracket 10 comprises a mounting portion 11, a pair of first supporting arms 12 and a pair of second supporting arms 13 extending slantwise and upwardly from opposite ends of the mounting portion 11. The mounting portion 11 comprises an elongated mounting plate 110 and a cylindrical fixture 111 extending downwardly from a central portion of the mounting plate 110. A through hole 1101 is defined in a center of the mounting portion 11. The first and second supporting arms 12, 13 extend from opposite edges of the mounting plate 110 of the mounting portion 11. A length of the second supporting arm 13 is longer than that of the first supporting arm 12, and a height of the second supporting arm 13 in a vertical direction is larger than that of the first supporting arm 12. The first supporting arms 12 are elongated poles and spaced from each other. An elongated first connecting portion 14 is mounted on and connects top ends of the first supporting arms 12 together and is parallel to a top surface of the mounting plate 110 of the mounting portion 11. The second supporting arms 13 are elongated poles and spaced from each other. An elongated second connecting portion 15 is mounted on and connects top ends of the second supporting arms 13 together and extends slantwise and downwardly from the top ends of the second supporting arms 13 toward the top ends of the first supporting arms 12. The solar plane assembly 40 is mounted on the first and second connecting portions 14, 15 and angles with mounting plate 110 of the mounting portion 11.

The reflector 30 has a generally V-shaped configuration. The reflector 30 comprises an arc-shaped first reflecting portion 31 and an arc-shaped second reflecting portion 32 extending upwardly and slantwise from an edge of the first reflecting portion 31. An area of the first reflecting portion 31 is smaller than that of the second reflecting portion 32. The first and second reflecting portions 31, 32 each have a concave surface 312, 322 facing downwardly and outwardly toward opposite directions. The first and second reflecting portions 31, 32 are mounted to the first and second connecting portions 14, 15 to mount the reflector 30 on the bracket 10. Outer edges of the first and second reflecting portions 31, 32 connect top surfaces of the first and second connecting portions 14, 15, respectively. The reflector 30 is spaced from the LED lamp 20. When the LED lamp 20 works, light emitted from the LED lamp 20 is reflected to orient towards different directions via the reflector 30, whereby the solar LED lamp assembly can have a large illumination angle.
The solar panel assembly 40 is mounted on the top end of the bracket 10. The solar panel assembly 40 is rectangular. The solar panel assembly 40 is used to convert the solar energy into electrical energy. The electrical energy is stored in the solar panel assembly 40, which connects with the LED lamp 20 via a switch (not shown). The solar LED lamp assembly is equipped with a light sensor (not shown) which can detect a brightness of an environment of the solar LED lamp assembly. When the environment is dark enough, the sensor sends a signal to the switch (not shown) to turn on the switch. The switch then electrically connects the solar panel assembly 40 and the LED lamp 20, thereby enabling the electric power stored in the solar panel assembly 40 to be provided to the LED lamp 20.
It is believed that the present invention and its advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the invention.
