Embodiment

[0045] The dual-module LED street lamp of the present invention includes a reflector, a module LED light source, a transparent lampshade (4), an upper housing of the street lamp, a lower housing of the street lamp, etc., all of which can be combined and installed using the prior art.

[0046] The reflector is made of high-temperature-resistant plastics, which are processed by molding technology of the prior art, as shown in the figure:

[0047] The matching parameter of its light reflection zone (1) or (2) is preferably: H4 / H5=24.9 / 43.9 (H4: H5=1: 1.76), H1=208mm, H2=69mm, H3=20mm, H6=21mm, The included angle a1=120°, the included angle a2=107°, the included angle a3=15°, the included angle a4=150°, and the included angle a5=127°.

[0048] The molded reflector shell; the reflective surface is electroplated to obtain a dual-channel light distributor product.

[0049] The dual-module LED street lamp reflector of the present invention is assembled with a matching street lamp hou...

Abstract

The inventive dual-module LED streetlamp fixture comprises a light-reflecting cover, a module LED light source, a transparent lampshade (4), a streetlamp upper housing and a streetlamp lower housing, the light-reflecting cover forms a light reflecting region (1) or (2) via two high-order non-spherical light-reflecting faces (A), (B), (C); the parameter characteristics of the light reflecting region are as below: H4:H5 is within a range from 1:1.5-1.9, H1 is within a range from 100mm-350mm, H2 is within a range from 10mm-150mm, H3 is within a range from 5mm-40mm, H6 is within a range from 5mm-50mm, an included angle alpha 1 is within a range from 60 degrees - 180 degrees, an included angle alpha 2 is within a range from 60 degrees - 180 degrees, an included angle alpha 3 is within a range from 5 degrees - 60 degrees, an included angle a4 is within a range from 75 degrees - 180 degrees, an included angle a5 is within a range from 75 degrees - 180 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 double-module LED light source type street lamp lamp 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 road 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 refle...
