Problems solved by technology

However, because urban road lighting has certain requirements, that is, illuminance, brightness and irradiation distance have different standards depending on the use of different roads, and the current LED street lamps cannot be used on the main road due to the lack of reflector structure and the small irradiation distance. Road, if you want to make its irradiation meet the requirements, you need to increase the output power of the LED lamp, which will increase the energy consumption

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0014] Such as figure 1 , figure 2 As shown, the reflector for LED street lights includes a top 1 , both ends of the top 1 have downward slopes 2 , and the top 1 has several lamp holders 3 and several ridges 4 . The rib 4 is integrally formed with the top 1 of the reflector. The ribs 4 are arranged along the direction between the two inclined surfaces 2, and between two adjacent ribs 4 there is a row of lamp holders 3 in the same direction as the ribs 4, and all the lamp holders 3 are placed between the two ribs 4; The sides of the middle part 5 of the rib 4 are linear, and the sides of the remaining two ends 6 are broken lines. One side 41 of the rib 4 is higher than the other side 42 , and the raised portion forms a boss 7 on the upper surface of the rib 4 . The upper surface 61 of the part 6 whose sides are folded lines is a double rhom...

Abstract

An LED street lamp reflector comprises a top having descending inclines at both ends and a plurality of lamp holders. The LED street lamp reflector is characterized in that: the top is provided with aplurality of lugs and the lugs are integrated with the top; the lugs are arranged in a direction between the two inclines, a line of lamp holders are arranged in the same direction as the lugs between two neighboring lugs, and all the lamp holders are arranged between two lugs; a middle portion of the lug is straight, side faces of other portions of both ends are curved; one side face of the lugis higher than the other side face, and the protrusion forms a boss on an upper surface of the lug; and the upper surface of the curved portion of a lug side is continuous rhombic. The lug arranged onthe top can reflect irradiating light of the LED lamp, thus improving illumination and uniformity of beams and increasing irradiation range.

Description

technical field [0001] The invention relates to a street lamp device, in particular to a reflector for an LED street lamp. Background technique [0002] Traditional urban road lighting uses high-pressure sodium lamps, which consume a lot of electric energy every year, and the high-pressure sodium lamps themselves have short service life and other shortcomings. With the rapid development of solid-state physics and the breakthrough discovery of new semiconductor materials in the 1990s, LED technology has achieved rapid development in the past 10 years. The emergence of white light LED, with its unique low voltage drive, small size, light weight, good color rendering, good dimming performance, long life (up to 20,000 hours), vibration resistance, not easy to damage, meet environmental protection requirements and other advantages , so that the semiconductor light source will become an ideal energy-saving light source for urban road lighting, so LED lights are gradually being us...
