Description
Technical field
The utility model relates to a kind of LED lamp housing based on the heat flow density principle.
Background technology
More common LED street lamp is made of parts such as lamp housing, radiator, led light source and driving powers at present, owing to need to effectively control junction temperature when LED is luminous, therefore can the LED radiator well be delivered to the heat on lamp housing, heat transfer plate and the module in the air, how effectively to utilize material and structure to mould suitable radiator, reducing to greatest extent aerial thermal resistance all is the problem that needs solution.
Summary of the invention
The purpose of this utility model is the LED lamp housing based on the heat flow density principle that a kind of good heat conduction effect will be provided.
The utility model realizes that the technical scheme of above-mentioned purpose is, a kind of LED lamp housing, has body, its innovative point is: also comprise heat transfer substrate and slot cover plate, have cellular perforation on the described body, described heat transfer substrate is embedded on the body, the back of described body has trough, described slot cover plate is installed in the body back, low streamlined in high both sides in the middle of the back of described body is, and the cross-sectional area of body is successively decreased to both sides by the centre.
The centre of described body also is distributed with radiating fin, and each radiating fin docks with cellular perforation.
Have groove on the described slot cover plate, have projection on the body, described groove and projection closely cooperate.
On the described heat transfer substrate light-distribution lens is installed, described light-distribution lens is fixed by the lens gland, and described lens gland is fixedly connected with heat transfer substrate.
Described heat transfer substrate is copper billet.
Low streamlined in high both sides in the middle of the utility model is by the body back, total quality is successively decreased to both sides by the centre, the cross-sectional area of body is successively decreased to both sides by light source, successively decreased backward by light source, because the bulk material thermal conductivity factor is certain, more near light source, body cross-section is long-pending larger, heat flow density is less, and heat of light source can effectively be derived.Contact the place with light source module and inlay a heat transfer substrate, heat transfer substrate is copper billet, can well derive the heat on the light source module.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side-looking cut-away diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.
As shown in Figure 1, 2, a kind of LED lamp housing, has body 1, also comprise heat transfer substrate 2 and slot cover plate 3, have cellular perforation 1-1 on the described body 1, described heat transfer substrate 2 is embedded on the body 1, the back of described body 1 has trough, described slot cover plate 3 is installed in body 1 back, low streamlined in high both sides in the middle of the back of described body 1 is, and the cross-sectional area of body 1 is successively decreased to both sides by the centre.Described heat transfer substrate 2 is copper billet.Place near light source module, total quality is successively decreased to both sides by the centre, the cross-sectional area of body 1 is successively decreased to both sides by the centre, successively decreased backward by light source, therefore cross-sectional area and the heat flow density of body 1 are inversely proportional to, and the cross-sectional area near the body 1 of light source is larger, and heat flow density is less, the heat that the unit interval passes through in the cross section of unit are is fewer, is conducive to the derivation of heat.Heat transfer substrate 2 adopts the mode of inlaying copper coin well the heat on the body 1 to be passed by liquid metal, reduces the temperature of module.
The centre of described body 1 also is distributed with radiating fin, and each radiating fin docks with cellular perforation 1-1.Be conducive to draining.
Have groove on the described slot cover plate 3, have projection on the body 1, described groove and projection closely cooperate.Cooperate closely, play waterproof action.
On the described body 1 light-distribution lens 4 is installed, described light-distribution lens 4 is fixing by lens gland 5, and described lens gland 5 is fixedly connected with body 1.
When the utility model uses, the led light source thermal conductive surface fits tightly on the heat transfer substrate 2 of body 1, also be on the copper billet, be connected and installed by liquid metal, light-distribution lens 4 is fixedly installed in the led light source exiting surface by lens gland 5, and lens gland 5 also is that copper billet is fastenedly connected with the heat transfer substrate 2 of honeycomb type LED lamp housing, 1 encapsulation process of light-distribution lens 4 and body, form airtight light-source chamber between the two, LED is in this light-source chamber.Described led light source is formed by LED package, comprises thermal conductive surface and light-emitting area, and the heat transfer substrate 2 that thermal conductive surface is close to heat transmission also is that copper billet is installed, and light-emitting area is installed light-distribution lens 4 and carried out secondary light-distribution.Described light-distribution lens 4 is comprised of incidence surface and exiting surface high transparent glass or resin-molded moulding.Described lens gland 5 peripheries are provided with the securing member that is connected with radiator.
The utility model is to make moulding by the high thermal conductivity alloy material, low streamlined in high both sides in the middle of the utility model back is, quality is successively decreased to both sides by the centre, the cross-sectional area of the body 1 of cellular LED lamp housing is successively decreased to both sides by the centre, is successively decreased backward by light source, and cross-sectional area and the heat flow density of body 1 are inversely proportional to, therefore the cross-sectional area near the body 1 of light source is larger, heat flow density is less, and the heat that the unit interval passes through in the cross section of unit are is fewer, is conducive to the derivation of heat.Near the place of light source module, quality is large, and area of dissipation is large, can effectively be delivered to heat in the air.Contact the place with module and inlay a copper billet, better heat conduction, overall appearance can adopt needed shape, also can adopt difform perforation on the body 1, increase the free convection of air, whole body 1 intermediate distribution radiating fin, and each fin well docks with perforation, high both sides were low in the middle of drainage channel between fin was, and were conducive to draining.
