In addition, in the middle of the application of reality, same LED lamp housing can dispose the bigger LED luminescence chip of general power sometimes, only disposes the less LED luminescence chip of general power sometimes.So under different power configuration situations, also be different to the requirement of lamp housing fin scale.The general power of LED luminescence chip is smaller, and is attached with large-scale fin, can cause waste; The general power of LED luminescence chip is bigger, and is attached with small-scale fin, can have a strong impact on the life-span of LED luminescence chip.So need a kind ofly can select the lamp housing of fin scale neatly for use according to luminous power.
Summary of the invention
The purpose of this invention is to provide a kind of can be according to luminous power and the corresponding more LED lamp housing of heat exchange radiator.
For achieving the above object, the present invention takes following technical scheme:
A kind of LED lamp housing of replaceable radiator comprises the lamp housing main body that die casting is made; On the lamp housing main body, be provided with the led module installed surface; The back side of described led module installed surface is the radiator installed surface; Wall thickness H between led module installed surface and the radiator installed surface is between 2～4mm; On the radiator installed surface, be provided with reinforcement, be distributed with the radiator installing hole on the reinforcement; Be distributed with the led module installing hole on the led module installed surface, the led module installing hole is corresponding with the position at reinforcement place.
Lamp housing main body of the present invention can separately be made with the radiator that is used for this lamp housing main body.Best with the lamp housing main body water proof and dust proof effect that die casting is made, also can reduce a lot of number of assembling steps.The radiator of making that adopt to stretch can be made into the very high shape of radiating efficiency, and its scale can be according to luminous power and waste of material is avoided in accurately customization.So the lamp housing product of being made by technique scheme both can have been taken into account the sealing property and the packaging efficiency of product, can take into account the heat dispersion and the production cost of product again, be one of technical scheme preferably.But, radiator is installed on the general lamp housing main body but can not obtains best effect, because if the wall thickness at the wall thickness on the lamp housing main body between led module installed surface and the radiator installed surface and other positions of lamp housing main body is suitable, then caloric requirement could arrive radiator through thicker wall body on the one hand, and thicker on the other hand wall body can cause the increase of material and weight.Thereby, for the heat that makes led module can be distributed as soon as possible, do not increase the cost and the weight of product yet, will consider usually the wall thickness between led module installed surface and the radiator installed surface is made thinner, generally between 2～4mm.So thin wall thickness can cause this position undercapacity again.For addressing this problem, the present invention is provided with reinforcement on the radiator installed surface.Reinforcement is except the intensity that can guarantee radiator installed surface and led module installed surface, the brill system position that also can be used as radiator installing hole and led module module installing hole, so radiator and led module needn't be considered to be installed on the wall body that is difficult to install because of thinner thickness, kill two birds with one stone.
Above-described radiator installing hole is preferably blind hole, and described led module installing hole preferably also is a blind hole.Like this, do not communicate between led module installed surface and the radiator installed surface, can avoid rainwater or dust to fall on the led module by radiator installing hole or led module installing hole.
Between lamp housing main body and radiator, preferably also scribble one deck heat-conducting silicone grease layer.
In addition, the lamp housing main body is provided with transparent lamp shade, preferably adopts the sealing ring of the closed loop be enclosed within the transparent lamp shade edge to carry out waterproof sealing between transparent lamp shade and the lamp housing main body.Moreover preferably going back one die casting on the lamp housing main body has the screw thread connector lug.This screw thread connector lug can directly be connected with existing waterproof connector lug, and need as prior art need not at first to adopt bolted mode to clamp a screw thread connector lug on the lamp housing main body, could connect the waterproof connector lug then.
The present invention is simple in structure firm, can select the radiator of different scales according to luminous power flexibly for use, and good seal performance, packaging efficiency height, production cost are lower, in light weight.
