Abstract
A heat dissipation device for LED tunnel lamps is composed of a heat dissipation device body, long heat dissipation fins, short heat dissipation fins, power source supports, a power source and a power source supporting plate. The high light effect is achieved by utilizing the power source efficiently. Due to the fact that the wave-shaped appearance design is adopted, air heat convection can be easily formed, the optimum heat dissipation effect can be achieved, the materials are saved, and the size of the heat dissipation device is reduced. The fins in the middle of the heat dissipation device protrude, the power source supports are used for supporting the power source cooperatively, and therefore the enough space around the heat dissipation device for forming air convection is guaranteed, and the heat dissipation effect is improved.
Description
Technical field
The utility model relates to LED lamp, especially a kind of LED Tunnel Lamp heat abstractor.
Background technology
Tunnel Lamp is a kind of when solving vehicle and sail into or roll tunnel away from, and " black-hole effect " or " white hole effect " that vision is produced due to the sudden change of brightness, for the special light fixture of tunnel illumination.Along with country further advances energy-saving and emission-reduction engineering, require more and more tighter to the effects of energy conservation and environmental protection of lighting, conventional tunnel light fixture adopts high-power tengsten lamp, low-pressure mercury vapour electricity-saving lamp, high-pressure blower, high-pressure mercury lamp, Metal halogen lamp, Non-polarized lamp etc., these light sources adopt high-voltage great-current and glass outer covers, and volume is large, Heavy Weight, frangible difficult transport, energy consumption is high, environmental pollution is serious, the life-span is short, illuminating effect is also undesirable.
There is many weak points in LED tunnel lamp common heat sink at present: reach enough radiating effects, adopt the aluminum alloy materials processing casting that thermal conductivity factor is higher, expensive, cost is higher; The common volume of radiator is larger, causes LED light fixture to seem heavy, is difficult to meet the requirement of light fixture appearance design; Radiator is often combined too tight with miscellaneous part, be unfavorable for circulation of air, affects radiating effect.LED lamp development is in recent years rapid, and one of core technology of LED light fixture is heat dissipation technology, and therefore radiator plays vital effect to the performance of LED light fixture.
In view of the foregoing, the structure of existing LED Tunnel Lamp radiator needs to improve.
Utility model content
The purpose of this utility model is in order to overcome deficiency of the prior art, and a kind of LED Tunnel Lamp heat abstractor is provided, and adopts waveform appearance design, is conducive to form air thermal convection current, reaches better radiating effect, and material saving, reduces radiator volume.
The utility model to achieve these goals, adopts following technical scheme: a kind of LED Tunnel Lamp heat abstractor is to be made up of: radiator body, long radiating fin, short radiating fin, power shelf, power supply, power supply gripper shoe; Waveform radiating fin is set on radiator body, and the middle part of radiator body arranges power supply gripper shoe, and the corresponding waveform radiating fin in both sides of radiator body arranges T shape power shelf, and between two T shape power shelfs, corresponding power gripper shoe arranges power supply.
Described waveform radiating fin is at least two groups, and every group is made up of at least two length of a film radiating fins and at least two short radiating fins.
The beneficial effects of the utility model are: the utility model high efficiency utilizes power supply to reach high light efficiency, adopt waveform appearance design, be conducive to form air thermal convection current, reach best radiating effect, and material saving, reduce radiator volume, scale projection in the middle of radiator, and be equipped with power shelf, hold up power supply, guarantee that radiator has enough spaces to form cross-ventilation, strengthens radiating effect around.
The utility model adopts corrugated appearance design, by two kinds of different radiating fins of height of long radiating fin and short radiating fin, form waveform curve, make the air of spreader surface form thermal convection current along radiating fin, take away amount of heat, greatly improved the radiating effect of radiator.Power shelf and power supply gripper shoe hold up power supply, make power supply and radiator keep certain space, contribute to better heat radiation.
The purpose of this utility model is to adopt waveform appearance design for the weak point of existing radiator, is conducive to form air thermal convection current, reaches better radiating effect, and material saving, reduces radiator volume.
