Description
Technical field
The present invention is relevant for a kind of light fixture, especially a kind of light fixture that promotes radiating effect.
Background technology
, be that TaiWan, China is announced " light fixture " patent of invention I316121 number please, disclose a kind of existing light fixture 9 with reference to shown in Figure 1.Should existing light fixture 9 comprise a shell 91, a radiator 92, a light-emitting component 93 and a radiator fan 94.The opposite end of this shell 91 has a transmittance section 911 and an electrical connection section 912 respectively, and the inner tip of this shell 91 is provided with a power supply circuit board 913, these power supply circuit board 913 these electrical connection sections 912 of electric connection in addition.This radiator 92 is the inside that is arranged at this shell 91, and this radiator 92 has several fins 921 and an accommodation space 922, and respectively this fin 921 is around the periphery that is arranged at this accommodation space 922.This light-emitting component 93 is incorporated into the root edge position of this radiator 92, and electrically connects this power supply circuit board 913, and can send light source towards this transmittance section 911.This radiator fan 94 is arranged in the accommodation space 922 of this radiator 92, and this radiator fan 94 has one drive circuit plate 941, these drive circuit board 941 these power supply circuit boards 913 of electric connection.
When these electrical connection section 912 energisings make these power supply circuit board 913 these light-emitting components 93 of actuating send light source generation heat; This power supply circuit board 913 sees through this drive circuit board 941 simultaneously and activates these radiator fan 94 starts, so that utilize these radiator fan 94 auxiliary these radiators 92 to dispel the heat.
Yet above-mentioned existing light fixture 9 roughly still has many shortcomings of the following stated when reality is used:
1, radiating effect is not good: the radiator 92 of above-mentioned existing light fixture 9 and radiator fan 94 mainly are to dispel the heat in order to be directed against the heat that is produced when this light-emitting component 93 operates; Owing to also can produce heat after these power supply circuit board 913 energising runnings; With the design of this radiator 92 and radiator fan 94, quite limited to 913 radiating effects that can provide of this power supply circuit board; Therefore, under long-time the use, cause these shell 91 inside to hoard too much heat easily, and then have a strong impact on the service life of this existing light fixture 9.
2, can't reach miniaturized design:, further must provide additional space can supply this power supply circuit board 913 to be provided with because this shell 91 comes members such as ccontaining this radiator 92 and light-emitting component 93 except having enough spaces; Therefore, cause the volume of this existing light fixture 9 to be difficult for reduction, can't be towards more compact direction research and development design.
Summary of the invention
The object of the invention is to improve above-mentioned shortcoming, so that a kind of light fixture that can effectively promote the integral heat sink effect to be provided.
Another purpose of the present invention provides a kind of light fixture that is easy to towards microminiaturized direction research and development design.
The light fixture according to the present invention comprises: a radiator, have a pedestal, and a side of this pedestal has a fixed part; One light-emitting component is arranged at the opposite side of this pedestal; One radiator fan is arranged at the fixed part of this radiator, and this radiator fan has an impeller and one drive circuit plate, and this drive circuit board drives this impeller rotation; And a power supply circuit board, be arranged between the pedestal and this radiator fan of this radiator, and this power supply circuit board electrically connects this light-emitting component.
Beneficial effect of the present invention is: because this power supply circuit board is to be arranged between the pedestal and this radiator fan of this radiator; So that when this radiator fan is introduced extraneous air-flow and flowed in this accommodation space, the heat that is produced in the time of can be simultaneously with this light-emitting component and power supply circuit board running is passed to extraneous space; So, make the present invention can effectively reach the effect that promotes the integral heat sink effect, and prolong the service life of light fixture relatively.
Light fixture of the present invention; Because this power supply circuit board is to be arranged in this accommodation space; Therefore must possess additional space compared to existing light fixture can ccontaining this power supply circuit board, and the present invention only need consider the physical dimension of this radiator towards the making of microminiaturization and application the time; So, can effectively reduce the volume of this light fixture, and then reach the effect that is easy to towards more compact direction research and development design.
