Light emitting diode road lamp of strong reflection

Abstract

A light emitting diode road lamp of strong reflection comprises a radiating substrate and a control substrate. Radiating fins are arranged on the back of the radiating substrate, a bulb fixing plate, a bulb and a reflecting bracket are arranged in the radiating substrate, and a transparent cover and a fixing frame are connected to the radiating substrate. A reflecting unit uniformly arranged is arranged in the reflecting bracket. A cover is arranged on the control substrate. The present invention is characterized in that the center of the reflecting unit is a pit, a bulb through hole is arranged in the pit, the two ends of the pit are step surfaces which are oblique outward, and the two sides of the pit are an oblique surface and a straight surface. The proposal has the advantages of high bright dipping rate due to multi-angle cross refraction, illumination shadow zone prevention, bright illumination, long light refraction distance and good illuminating effect on road surfaces.

Description

technical field [0001] The invention relates to street lamps used on roads, in particular to a strong reflective light-emitting diode street lamp, which belongs to lighting appliances. Background technique [0002] With the development of towns and road construction, various street lights have been installed on both sides of streets and highways. The main structure of the street lamp is the lamp holder and the light source (luminous body) installed on the light pole. At present, in order to vigorously promote the needs of energy saving and environmental protection, light-emitting diodes (LEDs) are widely used as light sources. LED light sources have long service life, good shock resistance, high Low efficiency and energy consumption, no harmful substances such as mercury. The LEDs used in street lamps are high-power light bulbs, and many light bulbs are combined together, so the lamp holder for fixing the light bulbs is a large porous connection seat, and an electrical cont...

AI Technical Summary

Problems solved by technology

One is that what the existing reflector adopts is a plane rectangle or a bowl-shaped paraboloid, and its light is radiated out, and the radiation light illumination will weaken rapidly with the increase of the distance. poor effect

The second is that the LEDs used in street lamps are high-power bulbs. Many bulbs generate a lot of heat after being illuminated. However, the current LED bulbs do not match the heat dissipation matrix, and the heat dissipation is insufficient, resulting in heat accumulation and affecting the service life of the bulbs.
