[specific embodiment]
In order to describe structure of the present invention and characteristics place in detail, as follows for following two embodiment now:
[embodiment 1]
See also Fig. 1 to shown in Figure 4, light emitting diode (LED) light fixture 10 of the tool radiator structure of embodiment 1 provided by the present invention consists predominantly of: a radiator 11, a fan 12, plural light emitting diode 13 and a controller 14.
This radiator 11 is cylindricality, and inside has the plural air flow channel 111 that runs through vertically.This fan 12 is arranged on the top of this radiator 11 and these air flow channels (passage) 111, and its running makes air-flow upwards flow.A plurality of light emitting diodes 13 are along axially being sticked on this radiator 11 surfaces of this radiator 11.This controller 14 electrically connects with this fan 12 and light emitting diode 13, controls these fan 12 runnings and makes air-flow upwards and to control these light emitting diodes 13 luminous.
In the present embodiment, this controller 14 has a temperature detector 141 and a control circuit 142, this temperature detector 141 is measured the temperature of this radiator 11, this control circuit 142, electrically connect with this fan 12, this temperature detector 141 and said these light emitting diodes 13, in order to accept the information of this temperature detector 141, when temperature exceeds a predetermined temperature, control this fan 12 and rotate and make air-flow upwards and to control these light emitting diodes 13 luminous.
In addition, as shown in Figure 4, this controller 14 also can be a delay circuit 143, this delay circuit 143 electrically connects with this fan 12 and these light emitting diodes 13, behind the scheduled time slot after lighting at these light emitting diodes 13, for example: five minutes, ten minutes etc., allow this fan 12 turn round, and it is luminous to control these light emitting diodes 13.
Please consult Fig. 3 and Fig. 4 again, the led lamp 10 of this tool radiator structure also can be set up a constant-current device 16, with this control circuit 142 or this delay circuit 143 both one of electrically connect, in order to stabling current to be provided, and then prolong the service life of assembly.
Next the function mode of embodiment 1 is described.
See also shown in Figure 5, under led lamp 10 user modes of the tool radiator structure of embodiment 1, by this control circuit 142 or this delay circuit 143 both one of allow electric current and said light emitting diode 13 electrical communication from this constant-current device 16, and make that these light emitting diodes 13 are luminous.Because light emitting diode 13 also can produce heat when producing light, and heat conducts to this radiator 11.This radiator 11 has these air flow channels 111, upwards flow because being subjected to the factor of these radiator 11 conduction heat so be arranged in the air of these air flow channels 111, simultaneously, the air of these air flow channel 111 belows also forms free convection and allows hot-air escape into the external world thereupon filling, and makes the radiating effect that this radiator 11 produces light emitting diode 13.Because the more existing fin type radiator structure of flow resistance in these air flow channels 111 is low, these air flow channels 111 so this air is flowed through and mode that these radiator 11 heat are discharged outside to, the effect of the more existing fin type radiator structure of radiating effect is good.
See also shown in Figure 6ly, these light emitting diodes 13 continue luminous and transmit the situation that heat to this radiator 11 or this radiator 11 is subjected to extraneous heating, can make that these radiator 11 temperature continue to raise.At this kind situation, embodiment 1 has two kinds of action kenels in response to processing:
First kind: the temperature of this this radiator 11 of temperature detector 141 test constantlies and transmission temperature information are to this control circuit 142.When the temperature of this radiator 11 is higher than a predetermined temperature, this control circuit 142 will make this constant-current device 16 and these fan 12 electrical communication, allow these fan 12 runnings produce and strengthen the situation that air-flow upwards flows, and strengthen the radiating effect of this radiator 11.This control circuit 142 can continue to keep this constant-current device 16 and these fan 12 electrical communication, closes the electrical communication of this constant-current device 16 and light emitting diode 13 up to this control circuit 142.
Second kind: this delay circuit 143 picks up counting in this constant-current device 16 of electrical communication and LED light lamp 13, behind this scheduled time slot, promptly start this fan 12 runnings, strengthen the radiating effect of this radiator 11, close the electrical communication of this constant-current device 16 and light emitting diode 13 up to this delay circuit 143.
By above-mentioned two kinds of action kenels, this radiator 11 continues heat absorption and the situation of temperature rising, can strengthen mobile that air makes progress by the continuous running of this fan 12, and then strengthen the effect of this radiator 11 heat radiations, compare with existing fin type radiator structure, when conducting heat to light emitting diode 13 light fixtures, still can keep preferable radiating effect in the external world.
[embodiment 2]
Seeing also shown in Figure 7ly, is the led lamp with radiator structure 20 of the embodiment of the invention 2, they are different with embodiment 1 be in:
One lamp socket 21, its bottom surface are fixed on this fan 12, and it has a plural louvre 211 and a heat radiation runner (passage) 212, and these louvres 211 are formed at these lamp socket 21 end faces in order to discharge hot gas, and this heat radiation runner 212 is to be communicated with these louvres 211.
One lampshade 22, have a plurality of pores 221 that run through this lampshade, this lampshade cover said light emitting diode 13 and is fixedly arranged on this lamp socket 21, in order to prevent that foreign matter bump light emitting diode 13 and the light that allows these light emitting diodes 13 be sent from producing the visual effect of diffusion, these pores 221 are in order to allow air therefrom flow into this lampshade 22.
The function mode of embodiment 2, see also shown in Figure 8, at the led lamp 20 of the tool radiator structure of embodiment 2 under user mode, itself and this embodiment 1 difference is that air system enters this lampshade 22 through air passing hole 221 earlier, then air forms hot-air through the heat transfer that air flow channel 111 is subjected to this radiator 11, escape into the external world through this fan 12 and this heat radiation runner 212 from these louvres 211 again, and the radiating effect that allows this radiator 11 produce light emitting diode 13.
By above narration, the beneficial effect that reaches of the present invention is as can be known:
(1) by air stream through air flow channel 111, and have better radiating effect.
(2) because rotating, this fan 12 make air-flow upwards strengthen the radiating effect of this radiator 11, so When the external world conducts heat to led lamp, still possess better heat sinking function.
