Embodiment
As shown in Figure 2, this has adjustable fan structure 2 of haircuting the luminous shading value in light unit and comprises radiation fan framework 21, radiation fan flabellum 22, control circuit board 222, be embedded in radiation fan framework 21 inner edge luminescence units 23 (can be for example LED luminescent component), and device is adjusted this luminescence unit 23 luminous shading value knobs 24 on radiation fan framework 21, and in order to fix this flabellum 22 and this control circuit board 222 fixed bases 25 constitute, wherein this control circuit board 222 comprises these luminescence unit 23 luminous shading value control circuit 2221 and fan drive circuits 2222 of may command.
This fixed base 25 is positioned on radiation fan framework 21 central positions, and in order to insert control circuit board 222 and flabellum 22, the fan drive circuit 2222 in the control circuit board 222 drives flabellum 22, makes its rotation send suitable wind-force to reach the effect of heat radiation.
In the control circuit board 222, shading value control circuit 2221 circuits set 4 supports 251 on this fixed base 25 are linked to 4 set luminescence units 23 of four appropriate locations of framework 21 inner edges respectively, this shading value control circuit 2221, and be linked to fan drive circuit 2222 and knob 24 by circuit respectively.
In this concrete example this number of holders with 4 as representative illustration, this support and luminescence unit quantity is not in order to restriction the utility model, quantity on this framework 21 all can as long as this number of holders can obtain secure, and this number of holders is better identical with this luminescence unit quantity, but during actual the use, this number of holders also can be different with this luminescence unit quantity, as long as can reach fixing and required luminous.
When this fan drive circuit 2222 drives flabellum 22 it is rotated simultaneously, because fan drive circuit 2222 is that electric power is independent with this shading value control circuit 2221, therefore can select whether to drive this shading value control circuit 2221, and drive this luminescence unit 23 by being linked to framework 21 inner edge luminescence units, 23 circuits and make it luminous, and this luminescence unit 23 can be linked to knob 24 by this shading value control circuit 2221, knob 24 control and adjust the purpose of these luminescence unit 23 luminous shading values.
The shading value control circuit 2221 in the utility model and the circuit diagram of fan drive circuit 2222 are asked for an interview in Fig. 3, and this fan drive circuit 2222 is known fan drive circuit, and it is easy to understand for knowing this skill person, therefore in repeating no more herein.
As shown in Figure 3, comprise variable resistor 22211 in the shading value control circuit 2221 in the utility model, it can control its resistance value by knob 24, when variable resistor 22211 resistance values improve, the related influence of meeting makes the voltage at luminescence unit 23 two ends reduce and makes bright and dark light, degree reduces, otherwise and when variable resistor 22211 resistance values reduce, can make the voltage at luminescence unit 23 two ends improve and make the bright and dark light degree promote, reach the effect of control luminescence unit 23 bright and dark light degree with this, except this variable resistor 22211, the circuit of this control circuit 2221 also is easy to understand and repeats no more for knowing this skill person.
Though more than be illustrated with regard to the utility model most preferred embodiment, but the utility model is not limited thereto, for example, be embedded in that the luminescence unit 23 of radiation fan framework 21 inner edges is non-to exceed with 4, and device can be placed in any position on this heat-dissipating frame according to the practicability design at the setting position of the luminous intensity knob 24 of the adjustment luminescence unit 23 on the framework 21, also can be arranged on any position of the electronic equipment that is equiped with the utility model radiation fan.
