Abstract
Disclosed is a radiator suitable for a light-emitting diode (LED) lamp. The radiator comprises a radiating base plate and a plurality of fins fixed on the radiating base plate. The fins are divided into a plurality of lines and evenly arranged on the radiating base plate. The distance between every two adjacent fins in the same line is 4.0-5.0 mm, and the distance between the fins in every two adjacent lines is 4.0-8.0 mm. The thickness of each fin is 0.2-2.0 mm, and the cross section of each fin is trapezoidal. The radiator is advanced in structural design, arrangement of horizontal and longitudinal distances of the fins and the shape of the fins is reasonable, a radiation effect of the radiator can be effectively improved, and the radiator is especially suitable for LED lamps and capable of improving radiation efficiency of the LED lamps and prolonging service life of the LED lamps in a certain extent.
Description
Technical field
The utility model relates to a kind of radiator, particularly a kind of radiator that is applicable to the LED lamp.
Background technology
The LED heat dissipation problem is the bottleneck of present semiconductor technology evolves.In the prior art, the photoelectric transformation efficiency of incandescent lamp only has 3%, and the photoelectric transformation efficiency of fluorescent lamp is about 15%, and the photoelectric transformation efficiency of LED is 10% ~ 40%, has 60% ~ 90% conversion to turn to heat.Junction temperature has significant impact to the LED life-span, when junction temperature when 60 ~ 80 spend, the LED thermal conversion efficiency is about 70% ~ 80%, 10 ℃ of the every risings of temperature of general electronic component, the life-span just becomes approximately half, 2 ℃ of the every risings of temperature, reliability will descend 10%.So the heat dissipation problem of LED is to improving its electricity conversion, improving its service life and reliability is significant.
Along with the continuous increase of LED lamp capacity, to the more and more higher requirement of heat dissipation proposition of LED lamp.In the prior art, the structural design of the radiator that the LED lamp uses is unreasonable, and radiating effect is general, thereby causes the radiating efficiency of LED lamp low, has reduced to a certain extent the service life of LED lamp.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides that a kind of structural design is more reasonable, the radiator that is applicable to the LED lamp of good heat dissipation effect.
Technical problem to be solved in the utility model is to realize by following technical scheme.The utility model is a kind of radiator of the LED of being applicable to lamp, be characterized in: this radiator comprises radiating bottom plate and the some radiating fins that are fixed on the radiating bottom plate, described radiating fin evenly is located on the radiating bottom plate by some row, the spacing that is in adjacent 2 radiating fins of same row is 4.0-5.0mm, and the spacing of the radiating fin of adjacent column is 4.0-8.0mm; The thickness of described radiating fin is 0.2-2.0mm, and the cross section of radiating fin is trapezoidal.
Technical problem to be solved in the utility model can also further realize by following technical scheme.The above-described radiator that is applicable to the LED lamp is characterized in: the pattern draft of described radiating fin is 3 °.Can further improve like this radiating effect of radiating fin.
Compared with prior art, the structural design of the utility model radiator is advanced, the horizontal and vertical spacing of radiating fin and the shape setting of radiating fin are more reasonable, can effectively improve the radiating effect of this radiator, be particularly suitable for the LED lamp, can improve the radiating efficiency of LED lamp, prolong to a certain extent the service life of LED lamp.
Description of drawings
Fig. 1 is a kind of cross-sectional structure schematic diagram of the present utility model.
The specific embodiment
Referring to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the present invention further, and do not consist of its Copyright law.
Embodiment 3, a kind of radiator that is applicable to the LED lamp, this radiator comprises radiating bottom plate 1 and the some radiating fins 2 that are fixed on the radiating bottom plate 1, described radiating fin 2 evenly is located on the radiating bottom plate 1 by some row, the spacing that is in adjacent 2 radiating fins 2 of same row is 4.5mm, and the spacing of the radiating fin 2 of adjacent column is 6.0mm; The thickness of described radiating fin 2 is 1.0mm, and the cross section of radiating fin 2 is trapezoidal.
In the radiator of embodiment 4. any one the described LED of being applicable to lamp of embodiment 1-3: the pattern draft of described radiating fin 2 is 3 °.
