Example Embodiment

[0015] The invention relates to a strong reflection light emitting diode street lamp, such as Figure 1-Figure 8 As shown, it includes a heat dissipation base 1 and a control base 10. The back of the heat dissipation base has a heat sink 11, and the heat dissipation base 1 is equipped with a bulb fixing plate 4, a bulb 5 (light-emitting diode, or LED), and a reflective bracket 3, and connections The transparent cover 6 and the fixed frame 2 on the heat sink base 1, the reflective bracket 3 is equipped with uniformly distributed reflective units 30, and the control base 10 is provided with a cover 103, which is characterized in that the reflective unit 30 is a center-inward recess 34. A light bulb through hole 35 is formed in the recess 34. The two ends of the recess 34 are stepped inclined (arc) surfaces 31 that face outward. Both sides of the recess 34 include an inclined surface 32 and a straight surface 33. In this solution, the reflecting unit 30 is a center-inward dimple 3...

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...
