Abstract

The aim of the utility model is to provide a heat dissipation structure for luminous diode lamps, which has the advantages of light weight, low cost and good heat dispersion effect. The utility model is realized in the way that the heat dissipation structure for luminous diode lamps comprises an electric connector and a driver, and is also provided with a metal lamp shade in which a luminous diode chip is arranged. Because the metal lamp shade can perform the function of heat dissipation and exert the function of a lampshade, the lamp shade and the heat dissipation structure of the luminous diode lamps are combined into a whole without adding a heat dissipation device so as to lighten the weight and reduce the cost.

Description

A kind of radiator structure of LED light lamp

Technical field

The utility model relates to a kind of radiator structure of lamp, particularly about the radiator structure of LED light lamp.

Background technology

Chinese patent ZL02206241.6 discloses a kind of large-power light-emitting diodes lamp, it comprises a light-emitting device that at least one LED core is installed, a printing opacity cell-shell, driver and shell thereof, an arrangements of electric connection, LED core is installed on the high thermal conductive substrate, and substrate contacts with a heat abstractor close thermal; The radiator structure of this large-power light-emitting diodes lamp is that a heat abstractor is set between printing opacity cell-shell and arrangements of electric connection, and weight is heavier, and cost is higher, and the effect of heat radiation is also relatively poor.

Summary of the invention

The purpose of this utility model is to provide weight lighter, and cost is lower, and the radiating effect radiator structure of LED light lamp preferably.

The utility model is achieved in that a kind of radiator structure of LED light lamp, comprises electric connector, driver, also is provided with metal shade, and light-emitting diode chip for backlight unit is installed in the metal shade.

Above-mentioned light-emitting diode chip for backlight unit is installed on the inner surface of metal shade.

Above-mentioned light-emitting diode chip for backlight unit is installed on the heat-conducting substrate, and heat-conducting substrate closely contacts with metal shade.

Because metal shade can play thermolysis, can also bring into play the function of lampshade, like this, the lampshade of LED light lamp and radiator structure is integrated, and needn't increase heat abstractor again, has alleviated weight, has reduced cost; In addition, owing to adopt metal shade to replace the glass cell-shell, can play thermolysis, increase area of dissipation, have better radiating effect in the uncovered part of metal shade and metal shade.

The specific embodiment

A kind of radiator structure of LED light lamp comprises electric connector 1, driver 2, also is provided with metal shade 5, and light-emitting diode chip for backlight unit 4 is installed in the metal shade 5.

A kind of embodiment as shown in Figure 2, above-mentioned light-emitting diode chip for backlight unit 4 is installed on the inner surface of metal shade 5.

A kind of embodiment shown in Fig. 3,4,5,6, above-mentioned light-emitting diode chip for backlight unit 4 is installed on the heat-conducting substrate 3, and heat-conducting substrate 3 closely contacts with metal shade 5.

Above-mentioned metal shade 5 can be column type shown in as shown in Figure 2 pyramid type, the trumpet type, Fig. 5,6 shown in Fig. 3,4, also can be the different shapes such as external form of various conventional lights, its material is a Heat Conduction Material, can be the alloy of aluminium, copper, iron, zinc etc. or this metalloid.

As shown in Figure 2, light-emitting diode chip for backlight unit 4 is fixed on the bottom of metal shade 5, is provided with driver 2, electric connector 1 on the top of metal shade 5; Driver 2 and electric connector 1 can separate insulation with insulating materials and metal shade, also driver 2 can be placed the outside of metal shade 5, have the hole at the top of metal shade 5, and lead can link to each other by the power supply or the electric connector of this Kong Bingyu outside.

Shown in Fig. 3,4, above metal shade 5, be provided with the column type cavity and match with metal shade 5, can be provided with driver 2, electric connector 1 in it.

Shown in Fig. 5,6, in the upper fixed of metal shade 5 locking device 51 is arranged, this locking device 51 can be fixed on LED light lamp on the ceiling.

Shown in Fig. 3,4, below light-emitting diode chip for backlight unit 4, in the metal shade 5, can be provided with reverberation bowl 31, be used for the light of light-emitting diode chip for backlight unit is concentrated.Open-mouth at metal shade 5 is equipped with a transparent glass cover 32, can make flat board or concave, convex mirror according to different needs, inner surface at the transparent glass cover can be handled the surface according to different needs, to reach different color, vision, optical effects; The transparent glass cover also can be plastics or other light transmissive materials.

Shown in Fig. 3,4, radiator 33 that can one-body molded different shape outside metal shade 5 is as strip, column, sheet or other shapes of being convenient to dispel the heat.

Shown in Fig. 2,5,6, in the bottom of metal shade 5, can open one or more hole 52, light from then on hole penetrates, with thus increasing heat radiation effect.

External power source links to each other with light-emitting diode chip for backlight unit 4 by electric connector 1, driver 2, makes light-emitting diode chip for backlight unit 4 luminous; Can series, parallel or string and company between the light-emitting diode chip for backlight unit 4, light-emitting diode chip for backlight unit 4 can be directly installed on metal shade 5 inner surfaces, light-emitting diode chip for backlight unit 4 also can be fixed on the heat-conducting substrate 3, heat-conducting substrate 3 can be metal substrate, material as aluminium, copper etc. or other high thermal conductivities, heat-conducting substrate 3 also can be an epoxy resin base plate, and heat-conducting substrate 3 can be that curved surface also can be the plane.
