The utility model content
The utility model proposes a kind of high power semi-conductor (such as LED) light source module, exists lighting angle to cause a plurality of led light source modules collocation of the not high and needs of service efficiency to use the technical problem of defective such as inconvenient installation for a short time to solve present led light source module.
The utility model adopts following technical scheme to realize: a kind of high power semi-conductor light source module, and it comprises: shell; Be fixedly connected the aluminium base that is provided with shell; Be fixedly installed on the semiconductor light sources on the aluminium base; On shell, there is the light that semiconductor light sources is sent to reflect anaclasis portion to external diffusion.
Wherein, anaclasis portion is processed by transparent material.
Wherein, anaclasis portion is processed by the PMMA material.
Wherein, have a plurality of pilot holes on the shell, have a plurality of fixing holes on the aluminium base, in a fixing hole of aluminium base, shell and aluminium base are fixed by the pilot hole locking that screw runs through on the shell.
Wherein, on the downside face of shell a plurality of cable clamping interfaces are set.
Wherein, the power line that is connected with semiconductor light sources is set in cable clamping interface.
Wherein, a plurality of capillary grooves that are used to prevent the liquid inflow enclosure in the cable clamping interface are set in cable clamping interface.
Wherein, semiconductor light sources comprises at least: the anodal diode that is connected with power supply; The anodal LED that links to each other with diode cathode.
Compared with prior art, the utlity model has following beneficial effect:
The high power semi-conductor light source module that the utility model proposes is compared with present traditional on the market module; Module thickness is below 15mm, and lighting angle can reach more than 140 °, and lighting angle is bigger; Can make full use of semiconductor light sources; Thereby also can illuminate scope bigger on the lamp box in the place very near apart from lamp box, or can not form the different zone bright spot of light and shade etc., go for very thin lamp box; And because lighting angle is big, lamp box of the same area uses the quantity of module also just few, thereby has improved the utilization rate of module greatly, and has reduced cost.
