Abstract

The utility model discloses a light-emitting diode (LED) ceiling lamp which is formed by a plurality of long cylindrical radiators hung on a base in a mutual separated mode, an LED light source, a driving power supply and the like. Each radiator is provided with an LED chip independently, no shading part is exposed, a radiating channel directly communicated with the external space of a lamp body is formed, the radiating face is wide, heat generated by LEDs can be transferred to the peripheral air to be dissipated quickly, the LED radiating effect is greatly improved, and the LED service life is prolonged. Meanwhile, each pair of the radiator and the LED is arranged in a separation mode, so that the LED ceiling lamp is novel in appearance structure and simple and saves materials.

Description

A kind of LED ceiling light

Technical field

The utility model relates to one and is arranged on illuminating high-power LED lamp in indoor ceiling.

Background technology

Be converted to heat energy because LED has the electric energy of most when luminous, need to carry out radiating treatment with radiator, just can avoid cause thermal damage and the light decay of LED, therefore, effective, high performance heat abstractor is most important to the working life of LED.Existing LED ceiling light radiator is all to adopt oblate or square block aluminium radiator, and multiple great power LEDs composition arrays are arranged in and on a module radiator, carry out radiating treatment.Need radiator often all can only hiddenly be contained in ceiling light inside for decorateeing, the bad radiating effect of the heat-conducting flow general character so not only and between extraneous air is poor, and therefore the outward appearance of ceiling light and structural design be also subject to larger restriction, be often difficult to meet the demand of designing and developing of LED ceiling light.

Summary of the invention

There is the problem of block aluminium radiator and the poor impact heat radiation of the interior space heat-conducting flow general character and the design of restriction ceiling light surface structure in order to solve existing LED ceiling light, the utility model will provide a kind of perfect heat-dissipating of radiator, is easy to carry out the LED ceiling light of some special construction designs.

The technical solution adopted in the utility model is: on ceiling light base, be spaced from each other and hanging branched height and be greater than the above elongated cylinder shape LED radiators of three times of diameters, fin above LED radiator is sun fancy from the outside scattering of cylinder central axis and arranges, the upper end of every LED radiator is fixedly connected with ceiling light base, lower end is that LED heat conducting circuit board only fills a LED chip of subsides, two electrical leads of each LED chip are copper paint envelope curves, are connected to the driving power on base along elongated cylinder shape LED radiator.Copper paint envelope curve resistance value is low, and the very high favourable LED pin heat radiation of thermal conductivity factor.

The beneficial effects of the utility model are: because each LED chip of ceiling light independently uses an elongated cylinder shape radiator, its good heat conduction effect, radiating surface is large, outside branched radiator is spaced from each other and is directly exposed to, form the spacious gas channel directly communicating with lamp body space outerpace, the heat that LED produces can be dispersed into space outerpace rapidly and can not be deposited in lamp body inside, greatly improve the heat dispersion of LED, extend the service life of LED, and each radiator and LED disperse to arrange to design exterior structure novelty, brief, save the LED ceiling light of material.

Brief description of the drawings

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is that the present embodiment elongated cylinder shape LED radiator is fixed on the structural map on ceiling light base.

Fig. 2 is elongated cylinder shape LED radiator cross-sectional structure figure.

Fig. 3 is the appearance effect figure of the present embodiment LED ceiling light.

Detailed description of the invention

As shown in Figure 1, a diameter is less than two centimetres, highly approximately ten centimetres, the elongated cylinder shape LED radiator 2 that adopts aluminium alloy to manufacture, formed by fin 21 and LED heat conducting circuit board 22, upper end is fixedly suspended on below ceiling light base 1, and the LED chip 3 of a watt is mounted on LED heat conducting circuit board 22, and two electrical leads 4 adopt copper paint envelope curve to reach on ceiling light base 1 and be connected with driving power 5 along the center of elongated cylinder shape LED radiator 2.The cross-sectional structure of LED radiator 2 as shown in Figure 2, six fin 21 can finding out LED radiator 2 are here the arrangement of sun fancy, article two, the copper paint envelope curve that black indicates is LED contact conductor 4, and above the left and right sides is first attached to LED heat conducting circuit board 22,90 degree right-angled bends extend to ceiling light base 1 along fin 21 angles towards LED radiator 2 central axial direction more respectively.Adopting copper paint envelope curve is that thermal conductivity factor is high as the advantage of LED lead-in wire, can help better LED heat radiation, reduces lead resistance value simultaneously and reduces electric heating loss.The present embodiment adopts 16 elongated cylinder shape LED radiators 2 to form 16 watts of square LED ceiling lights, and appearance effect as shown in Figure 3.LED radiator 2 itself just can play decorative appearance effect, is directly exposed to outward and needn't hides with lampshade or miscellaneous part, and its cost simple in structure is low, and radiating effect is good, can effectively reduce cause thermal damage rate and the light decay of LED.Actual product also can optionally adopt copper product to make LED radiator 2 to improve heat-conductive characteristic, and can, by different height and the space pattern that positional alignment becomes to need, design multiple ceiling light attractive in appearance.
