Abstract
The utility model discloses an LED (Light-Emitting Diode) down light. The LED down light is characterized by comprising a decorative cover, a surface cover, an LED light-emitting body, an emitting cup hood, a radiator, a power source box and a power source bracket, wherein the emitting cup hood and the surface cover are fixed on the decorative cover; the LED light-emitting body is mounted on the bottom surface of the emitting cup hood; the radiator is mounted at the backside of the bottom surface of the emitting cup hood and is in contacted connection with the emitting cup hood; the power source bracket is fixed on the decorative cover; the power source box is fixed on the power source bracket; and the LED light-emitting body is connected with the power source box through a circuit. The LED down light, disclosed by the utility model, has the advantages of being good in heat radiation effects of the LED light-emitting body, improving service life of the LED light-emitting body, being dust-proof and water-proof as the emitting cup hood and the surface cover are in a sealed state, avoiding mutual heat transfer as the power source box after being mounted on the power source bracket is separated from the radiator and the LED light-emitting body, solving the influence from other heat energy to the LED light-emitting body and being better for improving service life of the light.
Description
Technical field
The utility model relates to technical field of lighting fixtures, is a kind of LED Down lamp specifically.
Background technology
People adopt incandescent lamp or electricity-saving lamp (neon tube lamp) to throw light on usually; These ligthing paraphernalia energy consumptions are higher; People utilized light emitting diode (LED) to throw light on afterwards; Because LED utilizes the luminescent properties after semiconductor is switched on luminous, has advantage low in energy consumption, thereby becomes the emerging light source that substitutes the traditional lighting light source.But for high-power LED, the heat transfer in the needs solution LED use and the technical problem of heat radiation could improve LED service life like this.
Summary of the invention
The purpose of the utility model provides the LED Down lamp of a kind of simple in structure, good heat dissipation effect, long service life.
The purpose of the utility model realizes through following technical scheme.
A kind of LED Down lamp; It is characterized in that: said LED Down lamp comprises trim, cover, LED illuminator, emission cup cover, radiator, power pack and power shelf, and emission cup cover, cover are fixed on the trim together, and the LED illuminator is installed in the bottom surface of emission cup cover; Radiator is installed in the back side of the bottom surface of launching the cup cover and covers contact with the emission cup and is connected; Power shelf is fixed on the trim, and power pack is fixed on the power shelf, and the LED illuminator is connected with the power pack circuit.
Said emission cup cover is made up of with underside wall the emission cup, and radiator encloses fin by two and constitutes, the setting of staggering of each fin on the fin of outer ring and each fin on the inner ring fin.
Said trim is made up of cylindrical body and outer ring, and cylindrical body is connected on the outer ring.
The utility model compared with prior art has the following advantages:
The utility model is because the LED illuminator is installed in the bottom surface of emission cup cover, and radiator is installed in the back side of the bottom surface of launching the cup cover and covers contact with the emission cup and is connected, and particularly emission cup cover constitutes by launching cup and underside wall; Radiator is made up of two circle fin; The setting of staggering of each fin on the fin of outer ring and each fin on the inner ring fin, what the heat that sends of LED illuminator can be very fast like this passes through radiator heat-dissipation, the service life of having improved the LED illuminator; Emission cup cover becomes closed state with cover; Not only dustproof but also waterproof, and power pack installs the back through power shelf and all is in the state of separating with radiator, LED illuminator, therefore do not conduct heat mutually; Solved of the influence of other heat, more helped improving the service life of light fixture the LED illuminator.
