Abstract

The utility model discloses an embedded LED lamp, including lamp body and fin, the LED light emitting source of separation, the LED light emitting source is hugged closely with the fin, and the whole reflector that forms of lamp body is equipped with the fixed column on the back of lamp body, is fixed in the lamp body with the fin through screw and fixed column cooperation on, and the uncovered department of afterbody of reflector is arranged in to the LED light emitting source. The lamp shell and the radiating fin structure with the separable structure are adopted, so that the lamp shell can be made of materials with relatively low price, such as plastics and the like, the using amount of copper alloy or aluminum alloy can be saved, the manufacturing cost of the whole lamp is greatly reduced, and the radiating fin is still made of aluminum alloy or copper alloy with good radiating performance, so that the radiating requirement of the LED luminous source is met. And the lamp shell and the radiating fins are fixed in a screw mode, and the assembly process is simple and reliable.

Description

Embedded-type LED lamp

Technical field

The utility model relates to a kind of light fixture, especially a kind of Embedded LED lamp.

Background technology

There is the advantages such as energy-conserving and environment-protective due to LED, be applied to widely at present various lighting fields.But the use of LED chip has strict requirement to temperature, if excess Temperature must cause LED chip to burn, the heat dissipation problem of the consideration light fixture that the light fixture that for this reason uses LED to make must be strict.Have equally strict heat radiation requirement for embedded-type LED lamp, current this light fixture is the requirement that reaches above-mentioned heat radiation, and the fin after general whole lamp housing and lamp housing is all to adopt aluminium alloy or the moulding of copper alloy integrated die-casting.But in fact lamp housing plays very little effect to the heat radiation of embedded-type LED lamp, so it is relatively high to adopt the lamp housing of aluminium alloy or copper alloy manufacture not only to cause the waste of material to cause making cost simultaneously.

Summary of the invention

The purpose of this utility model is to provide a kind of embedded-type LED lamp, in the manufacturing cost of guaranteeing to have reduced in LED heat radiation requires whole lamp.

The utility model is to realize like this above-mentioned purpose:

Embedded-type LED lamp, comprise the lamp housing of separation and fin, LED light emitting source, LED light emitting source and fin are close to, lamp housing entirety forms reflection shield, the back side of lamp housing is provided with fixed leg, coordinated fin is fixed on lamp housing with fixed leg by screw, LED light emitting source is placed in the afterbody open-mouth of reflection shield.

Wherein, described lamp housing adopts injection molding.

Wherein, multiple fin are arranged and are fixed on lamp housing.

Wherein, described fin comprises multiple brace rod portion, has heat radiating fin radially to distribute and is connected with brace rod portion, and brace rod portion is provided with the screw socket post adapting with fixed leg position, and screw coordinates with fixed leg after through screw socket post.

Wherein, be also provided with astigmatic lampshade, astigmatic lampshade covers LED light emitting source and fixes with lamp housing.

Wherein, the afterbody of described reflection shield is provided with buckling groove, and described astigmatic lampshade snaps in buckling groove and fixes.

The beneficial effects of the utility model are: the lamp housing and the heat radiating fin structure that have adopted separable structure, lamp housing can be made by the relatively inexpensive material of material, as plastics etc., can save like this use amount of copper alloy or aluminium alloy and reduce greatly the manufacturing cost of whole lamp, and fin still adopts the good aluminium alloy of heat dispersion or copper alloy made, thereby ensure the heat radiation requirement of LED light emitting source.And lamp housing and fin adopt the mode of screw to fix, and assembly technology is simple and reliable.

Detailed description of the invention

With reference to Fig. 1, Fig. 2, Fig. 4 and Fig. 5, embedded-type LED lamp, comprise the lamp housing 1 of separation and fin 2, LED light emitting source 4, LED light emitting source 4 is close to fin 2, lamp housing 1 entirety forms reflection shield, the back side of lamp housing 1 is provided with fixed leg 3, is coordinated fin 2 is fixed on lamp housing 1 with fixed leg 3 by screw 5, and LED light emitting source 4 is placed in the afterbody open-mouth 6 of reflection shield.Lamp housing 1 and fin 2 structures of separable structure are adopted, lamp housing 1 can be made by the relatively inexpensive material of material, as plastics etc., can save like this use amount of copper alloy or aluminium alloy and reduce greatly the manufacturing cost of whole lamp, and fin 2 still adopts the good aluminium alloy of heat dispersion or copper alloy made, thereby ensure the heat radiation requirement of LED light emitting source 4.And lamp housing 1 and fin 2 adopt the mode of screw 5 to fix, and assembly technology is simple and reliable.

For ease of the making of lamp housing 1, described lamp housing 1 adopts injection molding.

For making a kind of fin 2 of specification can be applicable to the embedded-type LED lamp of sizes, when adopting large-sized embedded-type LED lamp, can adopt multiple fin 2 to arrange to be fixed on lamp housing 1 and realize.

Better fix with lamp housing 1 and reach good radiating effect for ease of fin 2, described fin 2 comprises multiple brace rod portion 7, there is heat radiating fin 8 radially distribute and be connected with brace rod portion 7, brace rod portion 7 is provided with the screw socket post 9 adapting with fixed leg 3 positions, and screw 5 coordinates with fixed leg 3 through screw socket post 9 is rear.

Because the light that LED light emitting source 4 sends is relatively concentrated, light is softer when light fixture is used, is unlikely to dazzling, and the utility model has also added astigmatic lampshade 10, and astigmatic lampshade 10 covers LED light emitting source 4 fixing with lamp housing 1.And for the ease of the installation and removal of astigmatic lampshade 10, the afterbody of described reflection shield is provided with buckling groove 11, when installation, directly astigmatic lampshade 10 is snapped in to buckling groove 11 fixing, very simple and reliable, with reference to Fig. 3 and Fig. 6.
