LED (light emitting diode) road lamp with high light-gathering property

Abstract

The invention discloses an LED (light emitting diode) road lamp with high light-gathering property. The LED road lamp comprises a road lamp support rod and a light source. The LED road lamp is characterized in that the road lamp support rod comprises a main support rod, a telescopic support rod and a secondary telescopic support rod, wherein the telescopic support rod is fixedly arranged at the upper end of the main support rod, and can be extended and retracted along the axial direction of the main support rod and be rotated around the end, fixed with the main support rod, of the telescopic support rod, the secondary telescopic support rod is arranged at the upper end of the telescopic support rod, a solar storage battery panel is fixedly arranged at the upper end of the secondary telescopic support rod and is used for supplying electric energy for a light source, a light source support rod is fixedly arranged on the telescopic support rod, and is in an inverted Y shape, the top end of the light source support rod is fixedly connected with an LED lamp head through a connecting joint, the LED lamp head can rotate around the connecting joint at any angle, an inward concave curve surface-shaped lamp shade is arranged in the LED lamp head, and a light diffusing area is arranged around the inward concave curve surface-shaped lamp shade in the LED lamp head. The LED road lamp has the advantages that the structure is simple, the light gathering property is good, the convenience in operation and use is realized, and the like.

Description

technical field [0001] The invention relates to the field of street lamps, in particular to a high-concentration LED street lamp. Background technique [0002] LED street lamp (Light Emitting Diode, light-emitting diode) is a semiconductor lighting lamp. It is a high-efficiency solid-state light source that can emit light with weak electric energy based on the semiconductor PN junction. Under a certain forward bias voltage and injection current, the holes injected into the P region and the electrons injected into the N region diffuse to the The active area then emits photons through radiative recombination, which converts electrical energy directly into light energy. It is a solid-state cold light source, which has the characteristics of environmental protection, no pollution, low power consumption, high luminous efficiency, and long life. Therefore, LED street lights will become the best choice for energy-saving renovation of road lighting. However, most of the LED street...

Problems solved by technology

However, most of the LED street lamps in the prior art have problems such as a single irradiation angle that cannot be adjusted, poor light-gathering performance, and poor heat dissipation performance, which affect the use effect, resulting in low light efficiency and difficult heat dissipation.

However, when this LED is used in the lighting field, there are many problems such as low light efficiency, increased cost, and difficulty in heat dissipation. Therefore, it is necessary to provide an improved LED street lamp to solve the problems existing in the prior art.
