Abstract
The utility model relates to a technical field of computer fan, in particular to a fan control circuit like race lamp flashing which is used for computer. The utility model comprises a fan driving circuit, one or more LEDs are connected in parallel between the power supply input end of the fan driving circuit and the LED control circuit, the LEDs are controlled by LED control circuit. The utility model only adds LEDs and LED control circuit, but has very simple structure and less cost is added, during rotation of the fan, the LEDs can flash regularly in order along the starting of the fan just like race lamp, so that the fan looks very beautiful and interesting, the utility model overcomes the detect that the appearance of the prior fan is too stiff, thereby absorbing more consumers.
Description
Technical field:
The utility model relates to the computer fan technical field, refers in particular to the fan control circuitry of employed band horse race lamp flicker on a kind of computer.
Background technology:
Computer fan in the market is mainly used in the computer system heat radiation, the drive circuit of this fan, I disclosed in application number is respectively the patent application of 0071289.5 (two gear selection circuit of speed change brush DC fan), 02271290.9 (drive circuit of the speed change brush DC fan that computer is controlled), 02271291.7 (three sections gear selection circuit of speed change brush DC fan), the function of this fan is being updated, but outward appearance is too inflexible, can not adapt to the trend that the computer profile constantly changes, make people's panesthesia that some a fly in the ointment be arranged.
Summary of the invention:
The purpose of this utility model just is to overcome above-mentioned defective, and the outward appearance of fan also can be full of variety.
The utility model is achieved by the following technical solution: the fan control circuitry of band horse race lamp, comprise fan drive circuit, it is characterized in that: the power input of fan drive circuit is with one or more LED in parallel between the LED control circuit, and LED is controlled by the LED control circuit.
The utility model has only increased LED and LED control circuit, the LED control circuit can be found in general conventional electricity teaching material, structure of the present utility model is very simple, increases cost seldom, but makes fan in operation process, startup along with fan, light-emitting diode can take turns flicker regularly, just as horse race lamp, makes fan look the entertaining that is rich in again very attractive in appearance, it has overcome the too inflexible defective of fan outward appearance in the past, can attract more consumers.
Description of drawings:
Accompanying drawing 1 is circuit theory diagrams of the present utility model
Embodiment:
See shown in the accompanying drawing 1, the fan control circuitry of band horse race lamp, comprise fan drive circuit, the power input of fan drive circuit is with four LED 1, LED2, LED3, LED4 in parallel between the LED control circuit, and LED is controlled by the LED control circuit.
The utility model has only increased LED and LED control circuit, the LED control circuit can be found in general conventional electricity teaching material, the end that its control LED is connected to the LED control circuit is in high potential in turn, make LED take turns conducting, the utility model structure is very simple, increase cost seldom, but make fan in operation process, startup along with fan, light-emitting diode can take turns flicker regularly, just as horse race lamp, makes fan look the entertaining that is rich in again very attractive in appearance, it has overcome the too inflexible defective of fan outward appearance in the past, can attract more consumers.
