Problems solved by technology

[0010] The purpose of the present invention is to aim at the serious loss of light energy due to the small lens shaping area relative to the divergence angle of the light source and the relatively large light absorption rate of the LED lens currently on the market. In addition, the lens The production cost is high, and the positioning in the street lamp is difficult, which will inevitably make the street lamp manufacturing process more complicated, the processing difficulty is high, and the actual problem of high production cost. To provide a high-efficiency strip reflector and its application in LED street lamps

Embodiment Construction

[0025] The accompanying drawings disclose specific embodiments of the present invention and its application in LED street lamps without limitation, and the present invention will be further described below in conjunction with the accompanying drawings.

[0026] It can be seen from Figure 1 that the basic unit of the trough-shaped reflector 2 is a strip-shaped groove 3 structure, and at least two neatly arranged light source installation holes 1 are arranged along the bottom center line of the strip-shaped groove 3, and the two sides of the strip-shaped groove 3 are symmetrical. The side curved reflector 5 is a symmetrical end reflector 4 at both ends, wherein: the side curved reflector 5 is a part of the quadric surface, the curved surface extends from the bottom of the groove to the edge, and the starting point of the quadric surface is tangent to the vertical groove At the bottom, the intercepted curved surface does not cross the inflection point of the quadric surface; the e...

Abstract

The invention relates to high active groove shape reflection shield and its application in the LED street lamp. The unit of the groove shape reflection shield is bar groove structure of which bottom is set two rows of light source mounting hole; two sides has symmetrical side curved surface illuminator; two ends have symmetrical end face illuminator. The illuminators are extended from groove bottom to binding edge. When the high active groove shape reflection shield is applied in the LED street lamp, the center distance of each light source mounting hole is bigger than 22mm. And one LED lamp is set in it.

Description

technical field [0001] The invention relates to a reflector and its application, especially a high-efficiency trough reflector and its application in LED street lamps Background technique [0002] With the development of LED chip technology and packaging technology, in line with the demand for high-luminous-flux LED products in the lighting field, power LEDs have gradually entered the market, especially in road lighting. Compared with the traditional 5mm LED, the power LED has a higher output luminous flux and a larger divergence angle. In order to make the high-power LED effectively used in the field of road lighting, it is necessary to carry out secondary optical design on the LED according to the LED light-emitting mode. Meet the road lighting standards of LED street lights. [0003] The power of traditional street lamps is 150w to 400w, but due to the large volume and divergence angle of these street lamp light sources, it is not convenient to effectively design the lig...
