Description

LED down

Technical field

The utility model relate to a kind of field of light fittings, especially a kind of LED down.

Background technology

Down lamp uses extensively, is mainly installed in smallpox trigger crown wall and is used as illumination.Along with the progress of science and technology, large-power light-emitting diodes is gradually improved as decoration and lighting source and is applied.But the chip of great power LED own operationally can produce amount of heat, if the heat dispersion of device is poor, will the service life of Down lamp be affected, and there is Heavy Weight in present Down lamp, the problems such as inconvenient are installed.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provides the LED down that a kind of thermal diffusivity is good, production cost is low.

In order to achieve the above object, a kind of LED down designed by the utility model, it comprises lamp socket, lampshade, LED light source, radiator, light guide plate, reflective membrane, bonnet, spring support; The bottom surface of described lamp socket has a light hole, is extended with sidewall at the edge of light hole to same direction; In the sidewall of lamp socket, be provided with lampshade, light guide plate, LED light source, reflective membrane and bonnet successively, lampshade is above light hole; Described radiator is fixed on the outside of sidewall, has plane perpendicular groove that is multiple and lamp socket on a heat sink, and described sidewall is provided with symmetrical grab, and spring support is provided with the bayonet socket coordinated with snap fit.

In order to improve the illuminating effect of LED light source, described light guide plate adopts the acryl plates of optical grade, and plate face is printed on light guiding points.

LED down of the present utility model, connection is fixed by screw thread between lamp socket, lampshade, LED light source, radiator, light guide plate, reflective membrane, bonnet, fulcrum bar of the spring is fixed with coordinating of buckle by bayonet socket, only spring snap fit need be placed in the installing port on roof during installation; Therefore, it has the features such as structure is simple, reasonable in design and easy to use.

Accompanying drawing explanation

Fig. 1 is explosive view of the present utility model.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model will be further described.

As shown in Figure 1, a kind of LED down that the present embodiment describes, it comprises lamp socket 1, lampshade 2, LED light source 3, radiator 4, light guide plate 5, reflective membrane 6, bonnet 7, spring support 8; The bottom surface of described lamp socket 1 has a light hole, is extended with sidewall at the edge of light hole to same direction; In the sidewall of lamp socket 1, be provided with lampshade 2, light guide plate 5, LED light source 3, reflective membrane 6 and bonnet 7 successively, lampshade 2 covers on above light hole, and lamp socket 1 is fixedly connected with by screw thread with between lampshade 2, light guide plate 5, LED light source 3, reflective membrane 6, bonnet 7; Described radiator 3 is fixed on the outside of sidewall, radiator 4 has plane perpendicular groove that is multiple and lamp socket 1, radiating effect is improved with the contact area of air by increasing, described sidewall is provided with symmetrical grab 9, spring support 8 is provided with the bayonet socket coordinated with snap fit 9, is fixed on sidewall by spring support 8 with coordinating of bayonet socket by snap fit.
