Abstract

The utility model discloses an LED (light-emitting diode) spotlight with a convection heat radiation device. The LED spotlight with the convection heat radiation device comprises a heat radiator, an LED light source and a light body, wherein the heat radiator is sleeved and fixed on the light body; the LED light source is arranged between the light body and the heat radiator. The LED spotlight with the convection heat radiation device is characterized in that the end surface of the light body is provided with a through hole; the part from the end surface of the bottom of the light body to the top of the heat radiator is through; a heat radiation air channel in the heat radiator corresponds to the through hole in the end surface of the light body so as to form heat radiation convection. According to the LED spotlight disclosed by the utility model, the convection heat radiation structure form is adopted, air steams can directly flow to the heat radiator from the end surface of the light body so as to take heat on the heat radiator away rapidly; the convection heat radiation mode overcomes the defect that a spotlight is installed in a wall body or a ceiling and is poor in heat radiation; the heat radiation efficiency is improved effectively.

Description

A kind of LED shot-light with thermal convection device
Technical field
The utility model relates to a kind of LED light fixture, especially a kind of LED shot-light with thermal convection device.
Background technology
Light emitting diode is referred to as LED(Light-Emitting Diode), it is the luminous semi-conductor electricity sub-element of a kind of energy, LED utilizes the luminescent properties after semiconductor energising luminous, because LED has low in energy consumption, the advantage of long service life, therefore utilizes the lighting of LED combination more and more general in daily life.LED shot-light in use caloric value is huge, and shot-light is generally all mounted in smallpox or body of wall, its radiating effect is had a greatly reduced quality more, the radiating effect of LED heat abstractor is on the market not enough to meet the heat radiation needs of this class shot-light, heat is dispersed and slowly can be caused the life-span of LED illuminator to be reduced, and even can produce potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of rational in infrastructure, good heat dissipation effect, the LED shot-light with thermal convection device that radiating rate is fast.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of LED shot-light with thermal convection device, comprise: radiator, LED light source and lamp body, described radiator socket is fixed on lamp body, and LED light source is located between lamp body and radiator, it is characterized in that: described lamp body end face is provided with through hole, the bottom end face of lamp body connects to the top of radiator, the corresponding formation of the lead to the hole site radiating convection of the radiation air groove on radiator and lamp body end face.
Preferably, described LED light source is connected with power supply driver by electric wire, and power supply driver is located at lamp body outside, and electric wire is connected with LED light source through radiator core.
Preferably, described lamp body is socketed to form toward interior from outer successively from front ring seat, locating ring and reflector, radiator and the mutual fit of front ring seat, and locating ring and reflector are pressed between radiator and front ring seat.
Preferably, described LED light source is fixed by screws on radiator, and the light-emitting area of LED light source is corresponding with reflector.
The utility model adopts after said structure, owing to having adopted the version of heat loss through convection, air-flow can directly flow to radiator from the end face of lamp body, heat on radiator is taken away fast, heat loss through convection form has overcome shot-light and has been arranged on the bad shortcoming of dispelling the heat in body of wall or smallpox, effectively improves radiating efficiency.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in the figure, a kind of LED shot-light with thermal convection device, comprise: radiator 1, LED light source 2 and lamp body 3, described radiator 1 is fixed by socket on lamp body 3, and LED light source 2 is located between lamp body 3 and radiator 1, it is characterized in that: described lamp body 3 end faces are provided with through hole, the bottom end face of lamp body 3 connects to the top of radiator 1, the corresponding formation of the lead to the hole site radiating convection of the radiation air groove 11 on radiator 1 and lamp body 3 end faces.
Preferably, described LED light source 2 is connected with power supply driver 4 by electric wire, and power supply driver 4 is located at lamp body 3 outsides, and electric wire is connected with LED light source 2 through radiator 1 core.
Preferably, described lamp body 3 is socketed to form toward interior from outer successively from front ring seat 31, locating ring 32 and reflector 33, radiator 1 and the mutual fit of front ring seat 31, and locating ring 32 and reflector 33 are pressed between radiator 1 and front ring seat 31.
Preferably, described LED light source 2 is fixed by screws on radiator 1, and the light-emitting area of LED light source 2 is corresponding with reflector 33.
Operation principle: LED shot-light is arranged in body of wall or smallpox, the through hole of lamp body 3 end faces until radiator 1 top connect always, air flows to radiator 1 along the through hole of lamp body 3 end faces always, in the process of Air Flow, Timing Belt is walked the heat accumulating on radiator 1, thereby plays the object that improves radiating effect.
The above is preferred embodiment of the present utility model; certainly can not limit with this interest field of the utility model; should be understood that; for those skilled in the art; the technical solution of the utility model is modified or is equal to replacement, do not depart from the protection domain of technical solutions of the utility model.
