Abstract
The invention discloses a radiator of an LED (light emitting diode). The radiator comprises a heat sink and a rib, wherein the heat sink is of a hollow cylindrical structure; the rib is arranged on the outer side wall of the heat sink; the heat sink and the rib are integrated structurally; the rib is arranged longitudinally along a sink cylinder; the length of the rib is greater than the height of the heat sink cylinder; and the end surface of the rib exposed to the heat sink is also provided with a radiating fan. The back part of the heat sink of the radiator for the LED is difficult to collect dust, and the radiation efficiency is improved effectively.
Description
Technical field:
The present invention relates to a kind of Light-Emitting Diode (LED) radiator.
Background technology:
Semiconductor lighting enters practical high-power illumination field of light fittings, and maximum restraining factors are to lead heat dissipation problem.At present, semiconductor lamp for reaching the illumination designing requirement, must be provided with a plurality of high-power chips in lamp body.Sometimes in a light fixture a plurality of light sources are set, each monomer light source is again by a plurality of high-power chip group encapsulates.The problem that a plurality of high-power chip structures are brought is that the junction temperature of LED raises, and influences luminance and the life-span of LED, even burns led chip.The radiator of prior art comprises heat sink and fin.Heat sink and ridge fin is the plane.In actual use, the substrate that led chip has been installed is fixed on the radiator belly, and the radiator ridge is parallel with horizontal plane.The radiator of this structure, ridge are built up dust very much, the easier accumulation dust of particularly heat sink ridge.Accumulate in the heat exchange that dust hinders radiator and air, the influence heat radiation.At open space (as street lamp, plaza lighting light fixture etc.), in the more environment of especially northern dust and sand weather, the spreader surface laying dust is very serious, cause sink-efficiency sharply to descend, the led chip thermal accumlation, temperature rises, light decay is accelerated, and has shortened LED service life greatly.
Summary of the invention:
The present invention overcomes the defective of prior art, provides a kind of radiating effect good LED LED radiator.
The present invention is achieved by the following technical solutions:
The LED LED radiator, comprise heat sink, fin, described heat sink be the hollow circuit cylinder body structure, described fin is arranged on the heat sink lateral wall, on the described heat sink and tab construction is an integral body, described fin vertically is provided with along heat sink cylinder, and the length of described fin is greater than heat sink cylindrical height, and described fin is placed on and also is provided with radiator fan on the heat sink end face.
Described fin is a straight line away from a heat sink side, and opposite side has oblique line or curve, and the oblique line of described fin or curvilinear sides form open hollow bulb, and the fan sheet of described radiator fan is arranged in the hollow bulb.
The heat sink hollow circuit cylinder body structure that is designed to of LED LED radiator of the present invention, described fin vertically is provided with along heat sink cylinder, the length of described fin is greater than cylindrical height, described fin is placed on heat sink end face and is provided with radiator fan, heat sink ridge is not easy to build up dust, effectively improved radiating efficiency, the heat that LED can be sent continues to diverge in rapidly among the air, guarantees the luminous efficiency and the ordinary life of high-power light-emitting diode light source.

The specific embodiment
Further specify the present invention in conjunction with the accompanying drawings and embodiments:
A kind of LED LED radiator, comprise heat sink 1, fin 2, described heat sink 1 is the hollow circuit cylinder body structure, described fin 2 vertically is provided with along heat sink 1 cylinder, described heat sink 1 and fin 2 structures on be an integral body, the length of described fin 2 is greater than heat sink 1 cylindrical height, described fin 2 is a straight line away from a side of heat sink 1, opposite side has oblique line, the oblique line side of described fin 2 forms open hollow bulb 3, described fin 2 is placed on heat sink 1 the end face and also is provided with radiator fan 4, and the fan sheet 5 of described radiator fan 4 is arranged in the hollow bulb 3 that fin 2 forms.
A kind of LED LED radiator, comprise heat sink 1, fin 2, described heat sink 1 is the hollow circuit cylinder body structure, described fin 2 vertically is provided with along heat sink 1 cylinder, described heat sink 1 and fin 2 structures on be an integral body, the length of described fin 2 is greater than heat sink 1 cylindrical height, described fin 2 is a straight line away from a side of heat sink 1, opposite side has curve, the curvilinear sides of described fin 2 forms open hollow bulb 3, described fin 2 is placed on heat sink 1 the end face and also is provided with radiator fan 4, and the fan sheet 5 of described radiator fan 4 is arranged in the hollow bulb 3 that fin 2 forms.
Embodiment is just for the ease of understanding technical scheme of the present invention; do not constitute limiting the scope of the invention; every interior any simple modification, equivalent variations and modification of perhaps according to technical spirit of the present invention above scheme being done that does not break away from technical solution of the present invention all still belongs within the protection domain of the present invention.
