The utility model content
The purpose of this utility model will overcome above-mentioned the deficiencies in the prior art exactly, and the LED overall lens formula light source module that a kind of light efficiency loss is few, assembling is convenient, it is convenient to change, versatility is good, can significantly reduce maintenance cost is provided.
The purpose of this utility model is achieved in that LED overall lens formula light source module, is made up of members such as heat sink section bar 1, solidus cover 2, rotating shaft I3, LED wiring board 4, led light source 5, seal 6, overall lens 7, rotating shaft II8, respirators 9.Respirator 9 embeds in the rotating shaft II8, rotating shaft I3 and rotating shaft II8 are installed on heat sink section bar 1 two ends respectively, solidus cover 2 is installed in the cable-through hole at heat sink section bar 1 two ends, led light source 5 is welded on LED wiring board 4, LED wiring board 4 fits tightly in heat sink section bar 1 inwall by heat-conducting medium, overall lens 7 covers led light source 5 and is installed on the heat sink section bar 1, seals by seal 6 pressings between overall lens 7 and the heat sink section bar 1.
Described overall lens 7 constitutes for the lens unit that has independent optical function.Overall lens 7 materials are safety glass or transparent PC or PMMA light transmissive material.
The front of described heat sink section bar 1 is that the light source installed surface is a flat type, without any enclosing that shuts out the light and rib.
Described heat sink section bar 1 is made by the aluminium section bar of high thermal conductivity, and the back side is provided with laterally some or the rib that vertically dispels the heat, and to increase the integral heat sink area of LED overall lens formula light source module, helps dispersing rapidly of heat.
Described respirator 9 helps getting rid of pernicious gases such as the interior pernicious gas of light-source chamber, steam.
Described LED overall lens formula light source module is an independently black box of monoblock type, and degree of protection reaches more than the IP65.
LED overall lens formula light source module adopts modular combination to install, and can entire module be rotated a certain angle by the rotating shaft I3 and the rotating shaft II8 at two ends, to realize the luminous intensity distribution demand of illumination occasion better.
The utility model can be by a plurality of modules combination and form street lamp, Tunnel Lamp, garden lamp etc. in conjunction with corresponding electric appliance and installation accessories and be applied to outdoor environment.
The utlity model has following beneficial effect:
1) heat sink section bar 1 front of the utility model LED overall lens formula light source module employing is a flat type, without any enclosing that shuts out the light and rib, has just rejected the 5% above light efficiency loss that the fitting structure factor causes; Do not adopt transparent glass and reflector, reduced by about 15% light efficiency loss; The light efficiency of light fixture can reach about 90% like this, than common LED light fixture light efficiency (generally about 70%) high about 20%.
2) the utility model LED overall lens formula light source module adopts modularization to install, and can adopt the module of varying number to realize the lighting demand of differing heights, different illumination according to the requirement of lighting environment; And the rotatable certain angle of each module realizes the optimal illumination requirement of different illuminations application scenario; Assemble convenient, change convenient, versatility is good, can significantly reduce maintenance cost.
