Description

LED fluorescent lamp heat radiation structure

Technical field

The utility model relates to a kind of LED fluorescent lamp heat radiation structure.

Background technology

Now, because the continuous development of LED lighting engineering, the performance of LED has had remarkable lifting; Its cost of manufacture is also more and more lower simultaneously; Therefore the LED lighting just possibly get in the average family, and the LED illumination is with a wide range of applications, no matter be commercialization or home lighting field.In family expenses or office lighting field, fluorescent lamp is a kind of indispensable lighting, can for work or family suitable lighting source is provided.Existing fluorescent lamp all is to adopt a LED lamp plate as lighting source mostly, and arranged in a straight line on the LED lamp plate have a lot of LED bulbs, forms linear light sorurce through the luminous fluorescent tube that makes of a plurality of LED bulbs.Though LED can directly change into visible light with electric energy; But because present technology limitation; Conversion ratio is not high, still has the part electric energy to be converted to heat energy, and LED is relatively more responsive to the temperature of itself; Can cause LED that electric energy is changed into the decrease in efficiency of visible light if heat can not in time conduct, even damage.In the existing LED fluorescent lamp, because the fluorescent tube volume restrictions makes its inside can not design radiator structure, therefore present LED fluorescent lamp all adopts a plurality of low power LED to be combined into light source, makes the brightness of fluorescent lamp not high enough, and illuminating effect is bad.If adopt great power LED as light source, can increase substantially the brightness of fluorescent tube, but the problem of also bringing heat not distribute, the too short discomfort of life-span that can make fluorescent lamp is with commercial applications.

The utility model content

To the deficiency that above-mentioned prior art exists, the purpose of the utility model provides a kind of LED fluorescent lamp heat radiation structure, and it has better heat radiating effect, can adopt great power LED to improve lighting tube brightness as light source.

To achieve these goals; The technical scheme that the utility model adopted is: LED fluorescent lamp heat radiation structure; Comprise the tubing that is stitched together and constitutes fluorescent tube and go out light shield, said tubing is that heat conduction good metal material is processed, and has the transverse slat that is structure as a whole with said tubing on the said tubing; The upper surface of said transverse slat is equipped with the LED lamp plate, and the lower surface of said transverse slat extends has fin.

Preferably, have two row LED bulbs on the said LED lamp plate, said LED lamp plate is anchored on the said transverse slat through screw, and said screw is between said two row LED bulbs.

Preferably, also has heat-conducting glue between said LED lamp plate and the said transverse slat.

Preferably, the lateral wall of said tubing has the heat radiation rib.

The utility model is compared the advantage that is had with prior art: through adopting heat conduction good metal material tubing, tubing with go out light shield and be spliced to form fluorescent tube, the LED lamp plate is installed on the transverse slat in tubing; The heat that the LED bulb sends conducts on the transverse slat via the LED lamp plate, distributes through the extended fin of the lower surface of transverse slat then, because tubing is longer; Transverse slat is identical with pipe length; The area of dissipation of transverse slat is enough big, and the heat that can well the LED bulb be sent distributes, and makes the LED bulb can remain on operate as normal under the temperature that can bear; Even if employing great power LED, radiating efficiency also can meet the demands.Therefore, the LED fluorescent lamp of the utility model has better heat radiating effect, can adopt great power LED to promote lighting tube brightness, strengthens illuminating effect.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is the structural representation of the utility model.

Among the figure: 10, fluorescent tube; 20, tubing; 30, go out light shield; 21, transverse slat; 22, fin 23, heat radiation rib; 40, LED lamp plate; 50, LED bulb; 60, screw.

The specific embodiment

The following stated is merely the preferred embodiment of the utility model, does not therefore limit the protection domain of the utility model.

Embodiment; See shown in Figure 1: the utility model is a kind of LED fluorescent lamp heat radiation structure, comprises the tubing 20 that is stitched together and constitutes fluorescent tube 10 and goes out light shield 30, it is characterized in that; Said tubing 20 is processed for heat conduction good metal material; And have the transverse slat 21 that is structure as a whole with said tubing 20 on the said tubing 20, the upper surface of said transverse slat 21 is equipped with LED lamp plate 40, and the lower surface of said transverse slat 21 extends has fin 22.The utility model is through adopting heat conduction good metal material tubing 20, tubing 20 with go out light shield 30 and be spliced to form fluorescent tube 10, installation LED lamp plate 40 on the transverse slat 21 tubing 20 in; The heat that LED bulb 50 sends conducts on the transverse slat 21 via LED lamp plate 40, distributes through the extended fin 22 of the lower surface of transverse slat 21 then, because tubing 20 is longer; Transverse slat 21 is identical with tubing 20 length; The area of dissipation of transverse slat 21 is enough big, and the heat that can well LED bulb 50 be sent distributes, and makes LED bulb 50 can remain on operate as normal under the temperature that can bear; Even if employing great power LED, radiating efficiency also can meet the demands.Therefore, the LED fluorescent lamp of the utility model has better heat radiating effect, can adopt great power LED to promote fluorescent tube 10 brightness, strengthens illuminating effect.

Preferably; Have two row LED bulbs 50 on the said LED lamp plate 40, said LED lamp plate 40 is anchored on the said transverse slat 21 through screw 60, and said screw 60 is between said two row LED bulbs 50; The advantage of design is like this; One adopts double LED bulb 50 can further promote fluorescent tube 10 brightness, strengthens illuminating effect, and two use screw 60 that LED lamp plate 40 is fastened on the transverse slat 21; The heat that LED bulb 50 is sent can conduct on the transverse slat 21 via LED lamp plate 40 quickly, avoids the heat accumulation in the LED bulb 50.Likewise, also have heat-conducting glue between said LED lamp plate 40 and the said transverse slat 21, also can make the heat conduction faster.In addition, in order to strengthen radiating effect, the lateral wall of said tubing 20 has heat radiation rib 23.The LED fluorescent lamp heat radiation structure of the utility model has better heat radiating effect, can adopt great power LED to promote lighting tube brightness, strengthens illuminating effect.
