The specific embodiment
For above-mentioned and other purpose of the present invention, feature and advantage can be become apparent, preferred embodiment of the present invention cited below particularly, and conjunction with figs. are described in detail below:
Please refer to shown in Figure 1ly, the light fixture that the present invention has an automatic dedusting function comprises a shell 10, heat radiation module 20, a light-emitting component 30 and a Control Component 40 at least.Wherein:
This shell 10 can be a hollow housing or docks combination institute mutually with several housings and constituted, and it is a principle can supply associated components be assembled in these shell 10 inside, in the present embodiment, this shell 10 by one first housing 11 and one second housing 12 mutually combine constitute.One end of this shell 10 is provided with an electrical connection section 111, the other end is provided with a transmittance section 121, and the periphery wall of this shell 10 has an inlet section 112 and an outlet section 122, and wherein this inlet section 112 is preferable places several fresh air inlets of the periphery wall of this first housing 11 to be constituted by the radial loop winding; This outlet section 122 is preferable to place several exhaust vents of the periphery wall of this second housing 12 to be constituted by the radial loop winding.
This heat radiation module 20 is arranged at the inside of this shell 10, and this heat radiation module 20 has a radiator fan 21 at least, these radiator fan 21 preferable tube-axial fans of selecting for use, and this radiator fan 21 can be in addition in conjunction with a radiating fin 22, but this radiating fin 22 is made by the material of heat conduction, this radiator fan 21 is incorporated into this radiating fin 22, whereby, and to promote the radiating effect of this heat radiation module 20.
These light-emitting component 30 preferable light emitting diode (LED), bulb or other backs that can switch on selected for use produce the light member.This light-emitting component 30 mutually combines with this heat radiation module 20, and a preferable side (as shown in Figure 2) that is incorporated into this radiating fin 22, and again, this light-emitting component 30 is electric connection with this electrical connection section 111.
This Control Component 40 has an one drive circuit 41 and a positive and reverse rotation control circuit 42, and this drive circuit 41 electrically connects the radiator fan 21 of this heat radiation module 20, and this positive and reverse rotation control circuit 42 then electrically connects this drive circuit 41.Whereby, this positive and reverse rotation control circuit 42 can be by the rotating of these drive circuit 41 these radiator fans 21 of control.In addition, this drive circuit 41 and positive and reverse rotation control circuit 42 can be encapsulated as an integrated circuit (IC).
The present invention has the light fixture of automatic dedusting function when reality is used, can be connected in the lamp socket (not illustrating) of positions such as wall, ceiling or desk by this electrical connection section 111, so that utilize general electric power system to make these light-emitting component 30 energisings produce light, and light is projected to the external world by this transmittance section 121, moreover, this transmittance section 121 more can be designed to have different colors (for example: green, yellow or redness etc.), so that this light-emitting component 30 can be by the light of these transmittance section 121 projection different colours.
Please refer to shown in Figure 2, when this light-emitting component 30 produces heat because of energising, this positive and reverse rotation control circuit 42 can be by this this radiator fan 21 reverse rotations running of drive circuit 41 controls, so that introduce air-flow by this inlet section 112 and from extraneous space, and can cooperate the conduction of heat of this radiating fin 22, further utilize this radiator fan 21 to make this air communication cross this outlet section 122 again heat is passed to extraneous space, reaching predetermined radiating effect, and then can prolong the service life of this light-emitting component 30.
Please refer to shown in Figure 3, when this radiator fan 21 is introduced in the process of air-flow by this inlet section 112 long-time, and the dust that causes air-flow to be carried secretly is when constantly being piled up in this inlet section 112, this positive and reverse rotation control circuit 42 can be rotated in the forward running by these drive circuit 41 these radiator fans 21 of control, flabellum design characteristics by tube-axial fan, then can make the air-flow adverse current of these housing 10 inside, and further be disposed to this housing 10 outsides via this inlet section 112, when this air communication is crossed in the process of this inlet section 112, can remove the dust that is deposited in this inlet section 112 simultaneously, and then can guarantee that this inlet section 112 can not form and block and influence its intake, so can effectively promote the integral heat sink effect, to prolong the service life of this light fixture 30.
More in detail, this positive and reverse rotation control circuit 42 can be by the rotating of these drive circuit 41 these radiator fans 21 of control, for example: light fixture of the present invention is when starting, can set after a scheduled time is turned round in these radiator fan 21 reverse rotations (as 10 seconds to 20 seconds), promptly control this radiator fan 21 and be rotated in the forward running one scheduled time (as 10 seconds to 20 seconds), to reach the function of automatic dedusting, after waiting to finish automatic dedusting operation, control this radiator fan 21 reverse rotations running again, with the operation of dispelling the heat; Perhaps also can when light fixture of the present invention start, directly set this radiator fan 21 and be rotated in the forward running in advance, after finishing automatic dedusting operation in advance, control this radiator fan 21 reverse rotations running again, with the operation of dispelling the heat.
As mentioned above, the present invention has the light fixture of automatic dedusting function and controls these radiator fan 21 reverse rotation starts by the positive and reverse rotation control circuit 42 of this Control Component 40 by this drive circuit 41, except that can keeping the original heat sinking function of this light fixture, can be rotated in the forward running by this radiator fan 21 of control in addition, to have the function that to carry out dedusting automatically simultaneously, therefore can effectively avoid this inlet section 112 to form obstruction and influence its intake.Generally speaking, light fixture of the present invention really can utilize this positive and reverse rotation control circuit 42 to reach the function of carrying out dedusting automatically, therefore, makes this radiator fan 21 introduce air-flow by this inlet section 112 smoothly, and then guarantee its radiating effect, with the service life of effective prolongation light fixture of the present invention.
