Abstract
The utility model discloses a heat radiation component for a LED lamp, which comprises a radiation fin board and a light-source-fixing board, on which air convection holes are provided. The utility model has the advantages that the heat radiation component for a LED lamp is located outside a reflection cup, is of simple structure, low cost, rapid and efficient radiation.
Description
Technical field
The utility model relates to a kind of illumination accessory, specifically is a kind of thermal component that is used for led lamp.
Background technology
Light emitting diode (LED) lighting must the great power LED of device more than one in order to reach high brightness.At present, the LED illuminating lamp of this high brightness all is that many high-power LED light sources are placed in the light fixture.For dustproof and waterproof, used light fixture also often adopts airtight design, and this just greatly reduces the radiating effect of light fixture.And many great power LEDs can produce a large amount of heat, and heat is particularly concentrated near central point, exceed more than 5 ℃ than lip temperature.If there is not appropriate thermal component, will make the led chip junction temperature too high, cause luminous efficiency seriously to descend, shortened the service life of LED.The patent No. is that 200420002838.6 utility model patent specification discloses a kind of large-power light-emitting diodes lamp, is provided with thermal component in the inside of light fixture.Yet this project organization complexity has improved the manufacturing cost of light fixture, and has broken down easily.
Summary of the invention
The purpose of this utility model provides a kind of reflective cup parts outside that is positioned at, and simplicity of design is cheap, and heat radiation is used for the thermal component of led lamp fast and effectively.The utility model has utilized the cross-ventilation principle, concentrates in the centre of light source fixed head the cross-ventilation hole is set, and makes light fixture energy quick heat radiating.
The purpose of this utility model is achieved through the following technical solutions:
The thermal component that is used for led lamp that the utility model provides, described thermal component comprise radiating fin plate and light source fixed head, on described radiating fin plate and the light source fixed head cross-ventilation hole are arranged.
The optimal technical scheme that the utility model provides is: the edge of described light source fixed head is provided with by the high-termal conductivity metal material and makes, with the perpendicular baffle plate of light source fixed head.
Another optimal technical scheme that the utility model provides is: the position in described cross-ventilation hole is based on the position near light source fixed head center.
The another optimal technical scheme that the utility model provides is: with fixture described light source fixed head and radiating fin plate are locked.
The another more preferably technical scheme that the utility model provides is: adopt threaded connection mode between described light source fixed head and the reflector, and scribble marine glue and/or be provided with O-ring seal at the two joint.
The another more preferably technical scheme that the utility model provides is: with fixture described light source fixed head and light emitting diode are locked, and coat heat-conducting cream at the joint of the two.

Among the figure, 1 is the light source fixed head, and 2 is the cross-ventilation hole on the light source fixed head, 3 is the joint of screwed light source fixed head and reflector, and 4 is the joint of light source fixed head and light emitting diode, and 5 is baffle plate, 6 is the radiating fin plate, and 7 is the cross-ventilation hole on the radiating fin plate.
Specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Embodiment 1
A kind of thermal component that is used for led lamp that the utility model provides comprises radiating fin plate 6 and light source fixed head 1.One or more cross-ventilation hole is arranged on radiating fin plate 6 and the light source fixed head 1.6 and 1 adopts aluminium, and the metal material of high-termal conductivity such as copper is made, to realize best heat conduction, radiating effect.The edge of light source fixed head 1 is provided with by the high-termal conductivity metal material, makes as materials such as aluminium, copper, and with the perpendicular baffle plate 5 of light source fixed head 1, baffle plate 5 can play the effect of dustproof and rainproof and have heat sinking function concurrently.Cross-ventilation hole 2 and 7 position be based on the position near the center of light source fixed head 1, and distributing the heat that many great power LEDs are concentrated near central point, and 2 and 7 positions on light source fixed head 1 and radiating fin plate 6 are corresponding to the same, communicate up and down.6 and 1 locking, make 6 and 1 to reach the best effect of combining closely with fixture.1 and reflector between adopt threaded connection mode, and scribble marine glue at joint 3 places of the two and be provided with O-ring seal, make the entire emission cup parts reach airtight completely.With fixture described light source fixed head 1 and light emitting diode are locked, and coat heat-conducting cream, further increase heat conduction, radiating effect at joint 4 places of the two.
Embodiment 2
The thermal component that is used for led lamp that the utility model provides comprises radiating fin plate 6 and light source fixed head 1.One or more cross-ventilation hole is arranged on radiating fin plate 6 and the light source fixed head 1.6 and 1 adopts aluminium, and the metal material of high-termal conductivity such as copper is made, to realize best heat conduction, radiating effect.Cross-ventilation hole 2 and 7 position be based on the position near the center of light source fixed head 1, and distributing the heat that many great power LEDs are concentrated near central point, and 2 and 7 positions on light source fixed head 1 and radiating fin plate 6 are corresponding to the same, communicate up and down.6 and 1 locking, make 6 and 1 to reach the best effect of combining closely with fixture.1 and reflector between adopt threaded connection mode, and be provided with O-ring seal at joint 3 places of the two.With fixture described light source fixed head 1 and light emitting diode are locked, and coat heat-conducting cream, further increase heat conduction, radiating effect at joint 4 places of the two.
In sum as can be seen, the supporting thermal component of the led lamp that the utility model provides is positioned at the outside of reflective cup parts, and the cross-ventilation hole on the light source heat radiation parts can dissipate near the heat that reflective cup parts produced it soon.The utility model simplicity of design, cheap, heat radiation fast effectively.
Should be noted that at last: above embodiment only is not intended to limit in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to the foregoing description, those of ordinary skill in the field are to be understood that: still can make amendment or be equal to replacement the specific embodiment of the present utility model, and do not break away from any modification of the utility model spirit and scope or be equal to replacement, it all should be encompassed in the middle of the claim scope of the present utility model.
