Embodiment
Please common reference Fig. 1 to Fig. 3, luminous air blower 10 of the present invention is used for dispelling the heat to system's (not shown), as host computer or server, its better embodiment comprises a fan 12, casing 14 and two light emitting diodes 16 that are used to accommodate described fan 12.Described light emitting diode 16 can substitute with other light-emitting component, and its quantity and color also can be set according to concrete needs, and quantity is at least one.
The edge of described casing 14 is provided with two symmetrical joints 18, is used for described luminous air blower 10 is fixed in the system of described needs heat radiation.Described light emitting diode 16 is located on the diapire of described casing 14 inside and respectively near a described joint 18, in order to avoid disturb the wind-force of casing 14 inside to flow.The bottom of described casing 14 also is provided with the rib 142 of the described fan 12 of some support fixation, and described light emitting diode 16 links to each other with the internal circuit of described fan 12 by being arranged in two leads 162 in the described rib 142.
Fig. 4 is the circuit diagram of the better embodiment of described luminous air blower 10, comprises a rotating-speed control circuit 100 and a rotation speed indicator 200.
Described rotating-speed control circuit 100 comprises transistor Q and motor 110 of a DC electrical source Vcc, a tool switching function, the base stage of described transistor Q receives a speed controling signal that is used to control motor 110 rotating speeds, described speed controling signal is PWM (Pulse WidthModulation, pulsewidth modulation) signal, the collector electrode of described transistor Q meets described DC electrical source Vcc, the emitter of the described transistor Q of power supply termination of described motor 110, the grounding end ground connection of described motor 110.Described fan 12 comprises described rotating-speed control circuit 100, and described rotating-speed control circuit 100 is located at the inside of described fan 12.
Described rotation speed indicator 200 comprises an inductance L as filtering device, a resistance R as pressure control device, the first Zener diode D1, second a Zener diode D2 and two described light emitting diodes 16.The power end of the described motor 110 of one termination of described inductance L is used to receive the index signal from described rotating-speed control circuit 100, and the other end is via described resistance R ground connection.The negative electrode of the described first Zener diode D1 and the second Zener diode D2 all is connected between described inductance L and the described resistance R, the anode of the described first Zener diode D1 and the second Zener diode D2 connects the anode of a described light emitting diode 16, the equal ground connection of the negative electrode of described light emitting diode 16 respectively.Described rotation speed indicator 200 all is located at the inside of described fan 12 except that described light emitting diode 16.
Described rotating-speed control circuit 100 is controlled the rotating speed of described motor 110 by described speed controling signal, thereby controls the rotating speed of described fan 12, and the rotating speed of the dutycycle of described pwm signal and described motor 110 is proportional.Described rotation speed indicator 200 shows the speed conditions of described fan 12 by the luminance of controlling described light emitting diode 16.
Because described speed controling signal is a pwm signal, if the dutycycle of described pwm signal is D, the voltage of described DC electrical source Vcc is U, the average voltage of the power end of then described motor 110 is D*U, when the dutycycle of described pwm signal increased, the average voltage of the power end of then described motor 110 also increased.By the filter action of described inductance L, know easily that when the average voltage of the power end of described motor 110 increases the DC component by the electric current on the described inductance L also will become greatly, the voltage phase strain on the then described resistance R is big.Because the dutycycle of described pwm signal and the rotating speed of described motor 110 are proportional, the voltage that promptly can draw on the described resistance R increases along with the increase of the rotating speed of described motor 110.
Wherein, the rotating speed of described fan 12 is divided into low speed and two gears of high speed, and the breakdown reverse voltage of the described first Zener diode D1 and the second Zener diode D2 increases progressively one by one.Can choose suitable Zener diode in the following manner as the described first Zener diode D1 and the second Zener diode D2, make its breakdown reverse voltage satisfy circuit requirements: when the rotating speed of described fan 12 reaches the bottom gear position, (can set) by software approach, utilize the magnitude of voltage that instrument is measured the resistance R two ends to be U1, the Zener diode of then choosing breakdown reverse voltage and be U1 is as the first Zener diode D1; When the rotating speed of described fan 12 reached the top gear position, the magnitude of voltage of measuring the resistance R two ends was U2, and the Zener diode of then choosing breakdown reverse voltage and be U2 is as the second Zener diode D2.
During 10 work of described luminous air blower, when the rotating speed of described fan 12 in low-speed range during to the high speed scope, the described first Zener diode D1 is reversed puncture, and is luminous with the light emitting diode 16 that the first Zener diode D1 links to each other; When the rotating speed of described fan 12 reached high speed, the described first Zener diode D1, the second Zener diode D2 all were reversed puncture, and two described light emitting diodes 16 are all luminous.
Described light emitting diode 16 can make luminous air blower 10 become honorable gorgeous when luminous, and the outward appearance visual effect that further makes the system that described luminous air blower 10 the is installed fashion attractive in appearance that becomes, for strengthening visual effect, the also available transparent material design of the bottom of described casing 14 or other parts, the color of described light emitting diode 16 also can be come collocation design as required.
Luminance according to described light emitting diode 16, can itself just can monitor its speed conditions by naked eyes direct observation luminous air blower 10, very convenient, the luminance of described light emitting diode 16 can be set according to actual needs, is not limited only to above-mentioned definite mode.
If do not need to monitor the rotating speed of described luminous air blower 10, the circuit of then described luminous air blower 10 only needs described rotating-speed control circuit 100 and described light emitting diode 16, and the anode of described light emitting diode 16 met described DC electrical source Vcc, minus earth gets final product, and no longer provides concrete circuit diagram here.
