Cut-off luminaire for double-module LED street light

Abstract

The invention discloses a cut-off light-reflecting cover used for a dual-module LED streetlamp, a light-reflecting cover is composed of an LED mounting hole (E) provided with two symmetrical module light sources and of two light reflecting regions (1), (2) thereof, the light reflecting region (1) or (2) thereof is composed of high-order non-spherical light-reflecting faces (A), (B), (C); the parameter characteristics of the light reflecting region (1) or (2) are as below: H5:H6 is in a range from 1:1.5-1.9, H1 is in a range from 30-100mm, H2 is in a range from 100-250mm, H3 is in a range from 50-125mm, H4 is in a range from 5-40mm, an included angle alpha 1 is in a range from 100 degrees to 200 degrees an included angle alpha 2 is in a range from 60 degrees to 180 degrees, an included angle alpha 3 is in a range from 60 degrees to 180 degrees, an included angle a4 is in a range from 5 degrees to 30 degrees, so that LED axial light beams are emitted evenly in a particular direction, which efficiently solves the axial problem of the LED light emitting and which can efficiently reduce the light of the lamp fixture illuminating behind lamp post and reduce ineffective light illumination of the streetlamp.rom 60 degrees to 180 degrees, an included angle alpha 3 is in a range from 60 degrees to 180 degrees, an included angle a4 is in a range from 5 degrees to 30 degrees, so that LED axial light beams are emitted evenly in a particular direction, which efficiently solves the axial problem of the LED light emitting and which can efficiently reduce the light of the lamp fixture illuminating behind lamp post and reduce ineffective light illumination of the streetlamp.

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 chip and packaging technology, energy saving, environmental protection and long life are the salient features of LED, and its LED solid-state lighting has become the current trend. In terms of application, especially in the aspect of modular LED road lighting, due to the cosine radiation characteristics of LED light, it is difficult to obtain the ideal light distribution effect with the existing spotlight cup technology, and it is difficult to meet the requirements of lighting products. Contents of the invention [0003] The purpose of the present invention is to solve the problem of the axiality of LED light source and its poor lighting effect, and aiming at the characteristics of the axiality of LED light source, to propose a modular LED street light reflect...
