Abstract
The utility model discloses an LED lamp which comprises a lamp holder, a lamp shade above the lamp holder, an LED light emitting module arranged between the lamp holder and the lamp shade and a heat radiating barrel located on the periphery of the LED light emitting module, wherein a plurality of heat radiating fins distributed along the periphery of the heat radiating barrel are arranged on the outer wall of the heat radiating barrel, and extension parts extending along the outer wall of the lamp shade are arranged on the top of the heat radiating fins. The LED lamp provided by the utility model has simple overall structure, the heat radiating areas of the heat radiating fins are increased because the extension parts are arranged at the top ends of the heat radiating fins, the heat radiating effect of the LED lamp is increased, and the service life of the LED lamp is prolonged.
Description
Technical field
The utility model belongs to the lighting apparatus design field, specifically relates to a kind of LED light fixture.
Background technology
As everyone knows, the LED light fixture has the characteristics of efficient low-consume, energy-conserving and environment-protective and long service life.Traditional incandescent lamp is replaced by the LED light fixture just gradually.But because the particularity of LED light fixture operation principle causes the LED light fixture to produce a large amount of heats in the use meeting, heat accumulation is too much, can make the LED light fixture produce light decay, causes the LED light fixture to descend service life.
For solving the heat dissipation problem of LED light fixture, the thermal component that is employed in the LED light fixture at present is provided with fin on every side more.But present heat radiating fin structure is single, and radiating effect is not good.The LED light fixture that designs a kind of perfect heat-dissipating is still present important technological problems to be solved.
The utility model content
The utility model discloses a kind of LED light fixture, this fitting structure is simple, adopts the fin of special construction, has strengthened the heat dispersion of LED light fixture, the service life of having improved the LED light fixture.
A kind of LED light fixture; Comprise lamp socket, at the lampshade above the lamp socket, be arranged on the LED luminescence component between lamp socket and the lampshade and be positioned at the peripheral heat-dissipating cylinder of LED luminescence component; Described heat-dissipating cylinder outer wall is provided with some fin that circumferentially distribute along heat-dissipating cylinder, and described fin top is provided with the extension that extends along the lampshade outer wall.
The design of fin extension has increased the area of dissipation of fin, has strengthened the heat dispersion of fin, and extension also can be taken away the heat that lampshade produces simultaneously simultaneously, avoids LED light fixture heat accumulation.
For ease of processing, avoid the illuminating effect of the long LED of the influence light fixture of fin simultaneously, described extension length is 0.5-2cm.The quantity that fin is provided with is generally confirmed according to the size of light fixture volume.For ease of the processing and fabricating of fin and heat-dissipating cylinder, can select fin and heat-dissipating cylinder for being wholely set, add the one-shot forming in man-hour.
For ease of the processing of fin, guarantee the radiating effect of fin simultaneously, can select fin thickness is 0.5-2mm.Described fin width is 0.5-1cm.
The LED light fixture overall structure of the utility model is simple, and the fin top is provided with extension, has increased the area of dissipation of fin, has increased the radiating effect of LED light fixture, improves the service life of LED light fixture.
Description of drawings
Fig. 1 is the structural representation of the LED light fixture of the utility model.
Fig. 2 is the vertical view of LED light fixture shown in Figure 1.
The specific embodiment
As depicted in figs. 1 and 2; A kind of LED light fixture; Comprise lamp socket 1, at the lampshade above the lamp socket 12, be arranged on the LED luminescence component between lamp socket 1 and the lampshade 2 and be positioned at the peripheral heat-dissipating cylinder 3 of LED luminescence component; Heat-dissipating cylinder 3 outer walls are provided with some fin 4 that circumferentially distribute along heat-dissipating cylinder, and fin 4 tops are provided with the extension 5 that extends along the lampshade outer wall.
The LED luminescence component generally comprises led light source, drive circuit board and led light source ON-OFF control circuit.Lamp socket 1 has external screw thread, is used for the fixing of LED light fixture.
Heat-dissipating cylinder 3 and fin 4 can be selected present technique field heat sink material commonly used for use for being wholely set, and for example can select aluminium alloy etc.The thickness of fin 4 is 0.5-2mm, and width is 0.5-1cm.The thickness of fin 4 and width need to confirm according to actual needs.Extension 5 length of fin 4 are 0.5-2cm, and concrete length can be confirmed according to actual needs.Lampshade 2 can be selected Transparent lamp shade for use.
In the actual use of LED light fixture in the present embodiment, the heat that the LED luminescence component produces conducts to fin through heat-dissipating cylinder, by fin heat is transferred to surrounding environment then; A heat part that produces on the lampshade is transferred to surrounding environment by the fin extension.
Claims (5)
