Abstract

A dual-channel module typed LED light source light distributor for street lamps of the invention comprises two light distributing channels (1) and (2) which are provided with reflective panels (A), (B), (C) and (D) which are either planar or cambered, and a module light source arranging hole (E). The included angle a5 between the reflective panels (A) and (B) is in a range of 60 to 95 degree; the included angle a6 between the reflective panel (C) and a horizontal line of the light distributor is in a range of 10 to 30 degree; the included angle a7 between (C) and (D) is in a range of 120 to 160 degree; the included angle 18 between (D) and (S) is in a range of 120 to 150 degree; the included angle a9 between the reflective panel (D) and the horizontal line of the light distributor is in a range of 50 to 70 degree; H1 is in a range of 30 to 200mm and H5 is in a range of 25 to 100mm; the light beams of the LED light source is reflected out through the light distributor and the two light beams complement each other's advantages, effectively solving the problem of the lighting axial direction of the LED; the actual lighting effect is strengthened by the light distributor and the changes of the arranging direction of the lamps; the lighting technical data requirements and the actual use effects of the lighting lamps can be reached or surpassed; and is provided with evident social and economic benefits.

Description

technical field [0001] The invention belongs to a lamp accessory, in particular to a module LED light source type street lamp lamp accessory product. Background technique [0002] At present, with the maturity of LED chips and packaging technology, energy saving, environmental protection, and long life are the salient features of LEDs, and LED solid-state lighting has become the current lighting trend. In terms of application, especially in road lighting, due to the problem of the axiality of LED light emission, it is difficult to obtain ideal lighting effects and meet the requirements of lighting-level lamps and lanterns with the existing spotlight cup technology of lamps. After successfully solving the heat dissipation problem of high-power LEDs, the company proposed the dual-channel light distributor suitable for dual-LED module light source structure street lamps in order to solve the axiality of LED light emission. Contents of the invention [0003] The object of the...
