A kind of lamp heat-radiating device
Technical field
The utility model relates to a kind of heat abstractor, relates in particular to a kind of lamp heat-radiating device.
Background technology
Along with energy cost constantly rises violently, relevant energy-conserving product promptly arises at the historic moment in recent years; Wherein, light emitting diode (LED) is because have advantages such as energy-saving and environmental protection, long-life, multicolour, and be widely used in show and lighting field in.
Is example to use light emitting diode as the light fixture of light-emitting component, can use the light emitting diode of high brightness, but because the light source that light emitting diode produced belongs to spot light, therefore using light emitting diode is provided with a plurality of light emitting diodes usually as light-emitting component when light fixture, so that produce the area source that is same as traditional fluorescent lamp pipe or bulb, improve luminous power simultaneously, make it to produce the brightness expression effect that is same as fluorescent tube or bulb.Simultaneously, general led lamp for long-time illumination use is understood construction more cooling mechanism, and its purpose be to prevent to derive because wafer is overheated light decay or associated components such as loses at problem.
Yet the at present general cooling mechanism that light fixture adopted that uses light emitting diode mainly directly utilizes metal shell, or the fin that one is located on the metal shell reaches the heat radiation purpose, therefore has following shortcoming:
Only utilize the mode of natural air convection current to dispel the heat, influence the radiating efficiency of light fixture easily because the surrounding enviroment condition changes.
Lamp casing is covered by dust easily, and then reduces original heat dissipation.
In order to promote radiating efficiency, existing technology is provided with fan in lamp casing, provide a power supply by each described light-emitting component and provide another power supply by described fan, just, take the power supply mode of dual power supply, make described fan produce air-flow and take away the heat that each described light-emitting component produces.
But this kind fan of the prior art is in case damage or inefficacy for some reason just lose thermolysis; Thus, in the time of can't starting cooling mechanism really when continuing to use light fixture, each described light-emitting component is easy to be damaged because of overheated.
As from the foregoing, how to propose a kind of heat dissipation technology to solve the various shortcoming of aforementioned prior art, real is problem demanding prompt solution.
Summary of the invention
Because the various shortcoming of prior art, a purpose of the present utility model is to provide a kind of lamp heat-radiating device that can start cooling mechanism really.
Another purpose of the present utility model is to provide a kind of lamp heat-radiating device that promotes radiating efficiency.
A purpose more of the present utility model is to provide a kind of optics unblanketed lamp heat-radiating device.
For reaching above-mentioned purpose and other purposes, lamp heat-radiating device described in the utility model is applied to a plurality of light-emitting components in the light fixture are dispelled the heat, and described light fixture provides a constant-current supply by each described light-emitting component, comprising: a substrate, for each described light-emitting component of carrying; One annular radiating seat is located at described substrate one surface, has heat dissipation channel that centering is provided with, convexedly stretches in a plurality of radiating fins of outer peripheral edges and inner peripheral and be positioned at a plurality of pilot holes between part two adjacent radiating fins respectively; And a fan, with the shared described constant-current supply of each described light-emitting component, and be installed on the described annular radiating seat, in order to produce radiating airflow.
In the described lamp heat-radiating device, described substrate comprises the periphery of corresponding each light-emitting component and a plurality of pores of being provided with, and described substrate is metallic circuit or high heat conduction and heat radiation substrate.Each described radiating fin is radial outer peripheral edges and the inner peripheral that is arranged at described annular radiating seat.Described a plurality of pilot hole comprises a plurality of C shape pilot holes and a plurality of U-shaped pilot hole.Described C shape pilot hole is positioned between the adjacent radiating fin of described annular radiating seat inner peripheral, wherein, described C shape pilot hole the position is set corresponding to described fan.Described U-shaped pilot hole is positioned between the adjacent radiating fin of described annular radiating seat outer peripheral edges, wherein, described U-shaped pilot hole the position is set corresponding to described substrate.Implement in the aspect one, described a plurality of C shape pilot hole and described a plurality of U-shaped pilot hole are set at interval.
Compared to prior art, fan of the present utility model and the shared constant-current supply of each described light-emitting component when in a single day fan damages or inefficacy for some reason, just can't supply power to each described light-emitting component.Thus, can prevent that each described light-emitting component from damaging because of overheated on the one hand, then can remind the user to change in good time or repair described fan on the other hand.Simultaneously, when using the utility model, owing to described substrate comprises a plurality of pores that the periphery of corresponding each light-emitting component is provided with, the air-flow that fan is produced can directly dispel or siphon away the heat that each light-emitting component produces, and increase area of dissipation relatively, in order to do promoting radiating efficiency.
In addition, the utility model is provided with a plurality of pilot holes between part two adjacent radiating fins, and more described pilot hole can be respectively applied for fan attachment and substrate; In other words, logical radiating fin is fan attachment simultaneously just, need not between fan and substrate corresponding fixed structure to be set in addition, and makes the direct bright dipping of each light-emitting component, so can provide a kind of optics unblanketed lamp heat-radiating device.
