Description
Technical field
The utility model relates to technical field of LED illumination, particularly relates to a kind of LED down.
Background technology
Down lamp is that one is embedded in ceiling, the lighting penetrated under light.From price, Down lamp uses electricity-saving lamp more common than LED down as light source, but from light efficiency, the luminous efficiency of LED down will be got well more than traditional energy-conserving barrel lamp.LED down generally comprises lamp cylinder, radiator, LED light source, reflector and face ring, radiator is connected to the lower port of lamp cylinder, LED light source is installed on a heat sink, reflector is located on LED light source, and by the connection of face ring and lamp cylinder, reflector is fixed in lamp cylinder, the installation of such radiator and reflector all needs the cooperation of lamp cylinder to install, in but radiator and reflector are wrapped in by the arranging of lamp cylinder, be unfavorable for heat radiation, and the heat that LED lamp bead produces is concentrated in the circuit board, easily like this cause the temperature on wiring board too high, make the components and parts on wiring board short for service life, thus directly affect the service time of Down lamp.Therefore, for solving the problem, spy provides a kind of new technical scheme.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of LED down.
The utility model is achieved through the following technical solutions:
A kind of LED down, comprise lamp socket and be arranged on the mounting spring of lamp socket both sides, wiring board and outside are covered with the radiator of heat sink, the side described wiring board being positioned at bright dipping is provided with several lamp pearl mount pads on the surface, described lamp pearl mount pad is thin-wall construction, and in little round table-like of the large lower end diameter of upper end diameter, the lower end of described lamp pearl mount pad is provided with LED lamp bead, the lower end of described lamp pearl mount pad and the outside being positioned at LED lamp bead is provided with reflector, the side of described lamp pearl mount pad is provided with several thermal vias, described radiator inside is provided with heat dissipation channel.
As preferably, described thermal vias shape is circular or kidney-shaped or prismatic.
As preferably, described heat dissipation channel is horn-like near wiring board side, is cylindric away from side.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the utility model is by arranging lamp pearl mount pad, LED lamp bead can be avoided directly to fix in the circuit board, lamp pearl generation heat can be effectively reduced like this affect the temperature of wiring board, improve the service life of components and parts on wiring board; By arranging heat dissipation channel, the temperature be convenient on wiring board gives out light fixture in time in heat dissipation channel, extends the service life of light fixture.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. lamp socket; 2. mounting spring; 3. wiring board; 4. radiator; 5. lamp pearl mount pad; 6. reflector; 7.LED lamp pearl; 8. thermal vias; 9. heat dissipation channel.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, a kind of LED down, comprise lamp socket 1 and be arranged on the mounting spring 2 of lamp socket 1 both sides, wiring board 3 and outside are covered with the radiator 4 of heat sink, the side described wiring board 3 being positioned at bright dipping is provided with several lamp pearl mount pads 5 on the surface, described lamp pearl mount pad 5 is thin-wall construction, and in little round table-like of the large lower end diameter of upper end diameter, the lower end of described lamp pearl mount pad 5 is provided with LED lamp bead 7, by LED lamp bead 7 being arranged on lamp pearl mount pad 5, make to define heat radiation cavity between LED lamp bead 5 and wiring board 3, LED lamp bead 7 is avoided directly to be fixed on wiring board 3, lamp pearl generation heat can be effectively reduced like this affect the temperature of wiring board 3, improve the service life of components and parts on wiring board 3, the lower end of described lamp pearl the mount pad 5 and outside being positioned at LED lamp bead 7 is provided with reflector 6, and the inner surface of reflector 6 is provided with reflective material layer, the light that LED lamp bead 7 can be produced is invested outside light fixture, improve the illuminating effect of light fixture.
The side of described lamp pearl mount pad 5 is provided with several thermal vias 8, described thermal vias 8 shape is circular or kidney-shaped or prismatic, accelerate the heat radiation of LED lamp bead 7, described radiator 4 inside is provided with heat dissipation channel 9, on described heat dissipation channel 9, close wiring board 3 side is horn-like, is cylindric away from side.During work, the temperature of wiring board 3 raises gradually, and now the hot inside air of light fixture rises, and through the trumpet-shaped wind-guiding effect of heat dissipation channel 9, the temperature on wiring board 3 is given out in time outside light fixture, extends the service life of light fixture.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
