Abstract
The utility model discloses an LED annular lamp, which includes a lamp body and a transparent PC cover body covering the upper surface of the lamp body, wherein the lamp body has a disc structure and is provided with an annular groove on the outer edge, and an LED light source plate is arranged in the annular groove. After the technical scheme is adopted, the LED light source is adhered into the groove with an aluminium alloy structure, so that the aluminium alloy structure becomes one part of an LED radiator, and the heat dissipation performance is better; and the aluminium alloy structure enables the lamp to be firm and endowed with certain degree of resistance to falling and collision, and meanwhile, compared with a PC tube structure, the aluminium alloy structure is more attractive and elegant.
Description
Technical field
The utility model relates to a kind of LED bulb lamp, belongs to lighting field.
Background technology
Light-emittingdiode (English: Light-Emitting Diode, be called for short LED) be a kind of semiconductor element.At the beginning indicator lamp, display boards etc. of being used as more; Along with the appearance of white light emitting diode, also be used as illumination.
It is the new type light source of 21 century, has long, conventional light source such as the cracky advantage that can't compare with it not of efficient height, life-span.When adding forward voltage, the light-emitting diodes physical efficiency is sent monochrome, discontinuous light, and this is a kind of of electroluminescent effect.Change the chemical composition of the semi-conducting material that is adopted, can make light-emittingdiode send near ultraviolet ray, visible light or ultrared light.
Because LED operating voltage low (only 1.5-3V), can active illuminating and certain brightness is arranged, brightness can use voltage (or electric current) to regulate again, itself is shock-resistant again, anti-vibration, life-span are long, therefore played increasing application in the demonstration field, especially utilize in the fluorescent lamp field, have brightness height, long technological merit of life-span.
But present fluorescent lamp lamp body generally all is to adopt the PC tubular construction, in operate as normal, temperature on the light source board is generally about 60 ℃, because its heat that gathers is not easy heat radiation, cause the caloric value height of LED equipment especially easily, thereby it breaks down than being easier to.
The utility model content
The utility model proposes at the existing bad shortcoming of LED light fixture heat dispersion, and the LED annular lamp of a kind of luminous efficiency height, perfect heat-dissipating is provided.
The utility model solves the problems of the technologies described above the technical scheme that adopted as following description:
A kind of LED annular lamp comprises lamp body and transparent PC cover body, and described transparent PC cover body covers the upper surface place of described lamp body, described lamp body is a disc-shaped structure, and its its outer edges place is provided with a cannelure, and the led light source plate is arranged among the described cannelure.
Further, preferred construction is that described led light source plate is made up of a plurality of LED lamp pearls.
Further, preferred construction is that described lamp body is made by aluminum alloy materials.
Further, preferred construction is that the lamp body inside at described aluminum alloy materials is provided with the endoporus that holds the built-in driving power of LED.
The utility model is after having taked technique scheme, because the led light source plate is attached in the groove of aluminium alloy structure, makes aluminium alloy structure become the part of LED radiator so good heat dispersion performance; And, indeformable because aluminium alloy structure makes light fixture firm, and have to a certain degree anti-to fall anti-collision ability, simultaneously, aluminium alloy structure is compared the PC tubular construction, has more effect elegant in appearance.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in detail, so that above-mentioned advantage of the present utility model is clearer and more definite.
Fig. 1 is the Facad structure schematic diagram of the utility model LED annular lamp;
Fig. 2 is the side schematic view of the utility model LED annular lamp.
The specific embodiment
Come the utility model is described in detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the Facad structure schematic diagram of the utility model LED annular lamp;
As shown in the figure, described LED annular lamp comprises lamp body 4 and transparent PC cover body 3, described transparent PC cover body covers the upper surface place of described lamp body, and described lamp body is a disc-shaped structure, and, its its outer edges place is provided with a cannelure, and led light source plate 1 is arranged among the described cannelure.
And described led light source plate is made up of a plurality of LED lamp pearls.
Among the preferred embodiment, described lamp body is made by aluminum alloy materials.And,, be provided with the endoporus 2 that holds the built-in driving power of LED in the lamp body inside of described aluminum alloy materials.
The utility model because described led light source plate is attached in the groove of aluminium alloy structure, makes aluminium alloy structure become the part of LED radiator after having taked technique scheme; And described aluminium alloy structure makes light fixture firm, and is indeformable, and has to a certain degree anti-to fall anti-collision ability.
In addition, the endoporus of described aluminium alloy structure has just held the built-in driving power of LED, and the heat that power supply is produced has also played good conduction simultaneously.
And it is planar that described PC cover makes the exiting surface of light fixture become cylinder by point-like, strengthened the brightness of light fixture greatly, and at indoor illuminating effect.
In addition, described aluminium alloy structure is compared the PC tubular construction, has more effect elegant in appearance.
It should be noted that; above-mentioned specific embodiment only is exemplary; under above-mentioned instruction of the present utility model, those skilled in the art can carry out various improvement and distortion on the basis of the foregoing description, and these improvement or distortion drop in the protection domain of the present utility model.
It will be understood by those skilled in the art that top specific descriptions just in order to explain the purpose of this utility model, are not to be used to limit the utility model.Protection domain of the present utility model is limited by claim and equivalent thereof.
Claims (4)
