Description
Technical field
The present invention is about a kind of light fixture, especially a kind of can be by the action moment and the drive manner of several radiator fans of control, to have the light fixture of several different cooling mechanisms.
Background technology
Existing light fixture with heat radiation module is announced " LED lamp radiator structure () " novel patent case M339636 number like TaiWan, China.This light fixture has a light fitting body, and this light fitting body is provided with several light emitting diodes and a lampshade, convexes with several fin in this light fitting body in addition.Whereby, when respectively this light emitting diode produced heat because of energising, auxiliary this light emitting diode of respectively this fin promptly capable of using spread the heat that is produced rapidly.
Yet, though the fin of existing light fixture can absorb the respectively heat of this light emitting diode because of being produced after switching on.But, still can't promptly carry out heat exchange after making this fin absorb heat because respectively this fin periphery does not have the design of other auxiliary heat dissipations; Therefore, cause this fin to absorb heat that respectively this light emitting diode produced after, still cause excessively problem such as long-pending heat of this fin easily, and then have a strong impact on the integral heat sink effect of this light fixture, make reduce the service life of this light fixture.
For solving the shortcoming of aforementioned existing light fixture, as shown in Figure 1, disclose another kind of existing light fixture 9, this light fixture 9 has a substrate 91, and a side surface of this substrate 91 is provided with several light emitting diodes 911, and the opposite side surface of this substrate 91 then is provided with a radiating fin 92; These radiating fin 92 two ends are respectively one first end 921 and one second end 922; First end 921 in this radiating fin 92 is provided with a radiator fan 93 in addition, so that constitute a heat radiation module.Whereby; But these radiating fin 92 fast Absorption are the heat of this light emitting diode 911 because of switching on and being produced respectively; And utilize this radiator fan 93 to order about air communication simultaneously and cross this radiating fin 92; So that this radiating fin 92 can promptly carry out heat exchange action with air-flow, and then promote the integral heat sink effect of this heat radiation module.
Please refer again to shown in Figure 1; Because this radiator fan 93 only is arranged at first end, 921 positions of this radiating fin 92; Therefore, 93 of this radiator fans can provide the radiating effect that gives this radiating fin 92, and only the zone with first end 921 that is adjacent to this radiating fin 92 is preferable; The zone of second end 922 of this radiating fin 92 is because of being away from this radiator fan 93, so radiating effect is relatively poor.In addition, after existing light fixture 9 long-term the uses, the too much dust of accumulation in this radiating fin 92 because this light fixture 9 does not have dedusting mechanism, also can influence the radiating effect of this radiator fan 93 relatively easily.The more important thing is, when this radiator fan 93 constantly turns round for a long time, will cause this radiator fan 93 to damage easily; Perhaps, when this light emitting diode 911 was overheated, single radiator fan 93 still can't effectively reduce the temperature of this light emitting diode 911.Generally speaking, the radiator fan 93 of existing light fixture 9 fails to provide more good and balanced thermolysis, so can't further promote the service life of this light fixture 9.
For improving the problems of aforementioned existing light fixture 9, or capable field technique personnel consider on this radiating fin 92, to combine more radiator fan 93.Yet, under the situation that several radiator fans 93 turn round simultaneously, though can temporarily promote the integral heat sink effect; But owing to do not have good structural design and controlling mechanism; Therefore, when several radiator fan 93 long-time runnings simultaneously, still causing respectively easily, this radiator fan 93 damages; Moreover, even several radiator fans 93 are set, can't solve also that this radiating fin 92 tires easily dust stratification dirt and the shortcoming that influences radiating effect, so still have necessity of improving.
Summary of the invention
