The utility model content
The purpose of this utility model will overcome above-mentioned the deficiencies in the prior art exactly, and the led 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 the led light source module, comprise by heat sink section bar 2-1, solidus cover 2-2, LED wiring board 2-3, led light source 2-4, rotating shaft I 2-5, seal 2-6, diffuser 2-7, rotating shaft II 2-8, members such as respirator 2-9 are formed, respirator 2-9 embeds in the rotating shaft II2-8, rotating shaft I 2-5 and rotating shaft II 2-8 are installed on heat sink section bar 2-1 two ends respectively, solidus cover 2-2 is installed in the cable-through hole at heat sink section bar 2-1 two ends, led light source 2-4 is welded on the LED wiring board 2-3, LED wiring board 2-3 fits tightly in heat sink section bar 2-1 inwall (front) by heat-conducting medium, diffuser 2-7 covers led light source 2-4 and is installed on the heat sink section bar 2-1, seals by seal 2-6 pressing between diffuser 2-7 and the heat sink section bar 2-1.
Described led light source 2-4 luminous intensity distribution is non-lambert's type.
Described diffuser 2-7 material is safety glass or transparent PC, PMMA light transmissive material.
Described heat sink section bar 2-1 front is a flat type, without any enclosing that shuts out the light and rib.
Described heat sink section bar 2-1 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 light source module, helps dispersing rapidly of heat.
Described respirator 2-9 helps getting rid of pernicious gases such as the interior pernicious gas of light-source chamber, steam.
Described led light source module is an independently black box of monoblock type, and degree of protection reaches more than the IP65.The led light source module adopts modular combination to install, and can entire module be rotated a certain angle by the rotating shaft I 2-5 and the rotating shaft II2-8 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) the heat sink section bar 2-1 front of the utility model led 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 secondary optical lens 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 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.
