Abstract

The utility model discloses an LED (Light Emitting Diode) down lamp with a good heat dissipation effect. The LED down lamp comprises a heat radiator base, wherein the heat radiator base is provided with a plane LED lamp board in an adhesion way, light transmitting glass is arranged above the plane LED lamp board, the light transmitting glass is provided with a surface ring, an inner ring surrounding the plane LED lamp board and the light transmitting glass is arranged at the outer sides of the plane LED lamp board and the light transmitting glass, the top surface of the inner ring is fixedly connected with the surface ring, and the bottom surface of the inner ring is fixedly connected with the heat radiator base. According to the LED down lamp disclosed by the utility model, the heat radiator base is directly utilized as a supporting surface of the plane LED lamp board, on one hand, the installation space at the inner part of a lamp body is greatly increased, the plane LED lamp board can be better arranged, and thus the better illuminating effect can be achieved; and on the other hand, heat emitted by the plane LED lamp board can be directly and outwards diffused through the heat radiator base, the heat dissipation effect of the plane LED lamp board can be greatly improved, and due to the structure, an illuminating product with higher power can be manufactured on the premise without increasing the size of the lamp body.

Description

A kind of LED Down lamp of good heat dissipation effect

Technical field

The utility model relates to a kind of lighting device, has to be a kind of LED Down lamp.

Background technology

The LED Down lamp is a kind of lighting that is embedded in the ceiling, and it can keep the integral body of building decoration unified and perfect, and it is inner that light source is hidden building decoration, and light source does not expose, free from glare, and people's visual effect is soft, even.LED Down lamp for slab construction, it generally is comprised of base plate, fin, luminescence unit, transparent glass, face ring etc., fin, luminescence unit, transparent glass etc. all are installed in the space that base plate and face ring limit, because the thickness of LED Down lamp is little, the close together of base plate and face ring, therefore the installing space of fin, luminescence unit, transparent glass etc. is minimum, and radiating effect is bad, has greatly limited the lifting of its lighting power.

Summary of the invention

For the problems referred to above, the utility model provides the LED Down lamp that the space increases in a kind of lamp, radiating effect is good, lighting power can promote.

The utility model is that the technical scheme that its technical problem of solution adopts is:

A kind of LED Down lamp of good heat dissipation effect, comprise foot of radiator, fit on the foot of radiator planar LED lamp plate is installed, the top of planar LED lamp plate is provided with transparent glass, transparent glass is provided with the face ring, the outside of planar LED lamp plate and transparent glass is provided with the interior ring that surrounds planar LED lamp plate and transparent glass, and the end face of interior ring is fixedly connected with the face ring, and the bottom surface of interior ring is fixedly connected with foot of radiator.

Preferably, described foot of radiator forms by the annular distance that is arranged at the center and with the intensive fin that the mode of ray is distributed in the annular distance periphery, be equipped with on the annular distance one with the locking wire plate of annular distance form fit, the planar LED lamp plate is connected with the power supply of outside by the electric wire that passes the locking wire plate.

Preferably, the described foot of radiator structure that is formed in one.

Preferably, the outside of face ring is provided with some spring support plates to downward-extension, is provided with mounting spring on the spring support plate.

The beneficial effects of the utility model are: the utility model is removed the base arrangement of Down lamp from, it directly utilizes foot of radiator as the supporting surface of planar LED lamp plate, it has increased the installing space of lamp body inside greatly on the one hand, so that the planar LED lamp plate can more preferably be arranged, thereby reach more excellent illuminating effect, the heat that sends of planar LED lamp plate can directly outwards shed by foot of radiator on the other hand, its radiating effect is improved greatly, and this structure can be made more powerful illuminating product under the prerequisite that does not increase the lamp body volume.

Description of drawings

Be further detailed below in conjunction with the drawings and specific embodiments:

Fig. 1 is overall structure figure of the present utility model;

Fig. 2 is blast structure chart of the present utility model.

The specific embodiment

See figures.1.and.2, the LED Down lamp of a kind of good heat dissipation effect of the present utility model, comprise foot of radiator 1, fit on the foot of radiator 1 planar LED lamp plate 2 is installed, the top of planar LED lamp plate 2 is provided with transparent glass 3, and transparent glass 3 is provided with face ring 4, and the outside of planar LED lamp plate 2 and transparent glass 3 is provided with the interior ring 5 that surrounds planar LED lamp plate 2 and transparent glass 3, the end face of interior ring 5 is fixedly connected with face ring 4, and the bottom surface of interior ring 5 is fixedly connected with foot of radiator 1.Planar LED lamp plate 2 of the present utility model and transparent glass 3 are installed in the space that foot of radiator 1, face ring 4 and interior ring 5 limit, this space and traditional product are basic identical by the space size that base plate, face ring and interior ring limit, but because the radiator part has not needed to take this segment space, therefore planar LED lamp plate 2 and transparent glass 3 the relative change of installing space greatly, they can adopt more excellent mode to arrange, thereby reach better illuminating effect.

In the present embodiment, Down lamp integral body is a circular configuration product, is that foot of radiator 1, lamp plate 2, transparent glass 3, face ring 4 and interior ring 5 etc. all are circular configuration accordingly therefore.

As preferably, as shown in this embodiment, foot of radiator 1 forms 12 by the annular distance 11 that is arranged at the center and with the intensive fin that the mode of ray is distributed in annular distance 11 peripheries, and the foot of radiator 1 preferred integrated formed structure that adopts is realized.The foot of radiator 1 of this structure has fabulous radiating effect.Be equipped with on the annular distance 11 one with the locking wire plate 6 of annular distance 11 form fit, planar LED lamp plate 2 is connected with the power supply of outside by the electric wire that passes locking wire plate 6.

In addition, the outside of face ring 4 is provided with 3 and is provided with mounting spring 8 on the spring support plate 7 to the spring support plate 7 of downward-extension, and these 3 spring support plates 7 are uniformly distributed in the face ring outside.When mounted the mounting spring of both sides is holded up, in lamp body inserted installing hole, the jack-up that firmly makes progress gets final product on the automatic clamping, and was easy installation and reliable.

Embodiment of the present utility model is not restricted to the described embodiments, as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
