The utility model discloses an LED tube light comprising a casing, a heat radiator in the casing and an LED light source, wherein the upper part of the casing is provided with a power supply, a reflecting shade and a light-transmitting board; a heat radiation base plate of the heat radiator is in the shape of a cylindrical ring, the outer part of the heat radiation base plate is uniformly provided with a plurality of groups of heat radiation fins, the heat radiation base plate is in fit with the heat radiation fins through a hot plug, and the periphery of the heat radiation base plate is provided with a plurality of ventilation holes; a decoration panel and replaceable decoration plastic are arranged below the light-transmitting board; and the decoration panel is used for fixing the decoration plastic. The heat radiator of the LED tube light adopts the design of the ventilation holes of the heat radiation base plate and the design of large spacing among the heat radiation fins, thereby having good air convection during heat radiation and being easier to radiate heat; and simultaneously, the replaceable decoration plastic can lead the periphery of the tube light to change color freely.
Description
Technical field
The utility model relates to a kind of LED Down lamp.
Background technology
LED (light emitting diode) is a fixedly luminescent device of a kind of semiconductor, when electric current can send the light of multiple color during by it.LED does not have that mercury is nontoxic, no electromagnetic pollution, no harm ray etc., is fit to very much make illuminating lamp.The LED Down lamp is exactly to utilize a kind of as the produced lighting of light source of LED.The LED Down lamp has long, the advantage such as little, shock-resistant that takes up room in power and energy saving, life-span, but existing LED Down lamp will be widely used in lighting field, also has following defective: the radiator heat-dissipation of existing LED Down lamp is slow, and the color of Down lamp periphery is single.
The utility model content
The utility model provides a kind of LED Down lamp formally in order to overcome above-mentioned deficiency, its efficient height, and rapid heat dissipation, the replacing color can be liked according to the user in the Down lamp periphery.Main innovate point of the present utility model is to adopt novel heat radiator dedicated, and the heat-radiating substrate periphery of radiator has some air vents, has good cross-ventilation when making heat radiation, and the easier heat that makes distributes.
The utility model specifically is to implement like this: a kind of LED Down lamp, comprise housing, radiator in the housing, led light source, housing top is equipped with power supply, reflection shield and light-passing board, it is characterized in that: the heat-radiating substrate of described radiator is the cylinder annular, the outside many group radiating fins that evenly distribute of described heat-radiating substrate, described heat-radiating substrate and radiating fin are connected by the heat plug, described heat-radiating substrate periphery has some air vents, described heat-radiating substrate lower central is provided with the cooling base that led light source is installed, and described cooling base is linked to each other by many radiating ribs with heat-radiating substrate; Be provided with decoration panel below the described light-passing board and decorate plastics, described decoration panel is used for fixing the decoration plastics.Described decoration plastics can be changed according to the personal like.The radiating fin of described radiator is the straight-tooth shape, is the periphery that big spacing is uniformly distributed in cylinder annular heat-radiating substrate.Described power supply is contained in the power pack on the housing, by power supply cap seal mouth.Described light-passing board is circular PC light-passing board.
Advantage of the present utility model is: radiator of the present utility model adopts the air vent design of heat-radiating substrate and the big spacing design between radiating fin, has good cross-ventilation when making heat radiation, the easier heat that makes distributes, simultaneously, removable decoration plastics make around the Down lamp conversion color at any time.
