Embodiment Construction

[0015] The present invention will be described in detail below in combination with specific embodiments.

[0016] A kind of eye protection lamp frequency control circuit of the present invention is provided with controller 104, is connected with power supply input circuit 101, high frequency output circuit 102, encoding circuit 105, frequency display circuit 106 on controller 104; High frequency output circuit 102 is connected with a load lighting circuit 103; the power input circuit 101 and the high frequency output circuit 102 are connected. The model of the controller 104 is PIC13F73.

[0017] The external alternating current passes through the power input circuit 101 , passes through the transformer B1 and the bridge rectifier DX, and passes through the triode BG2 to provide working current for the high frequency output circuit 102 and the controller 104 . After the controller 104 gets the voltage, it enters the working state, provides the working frequency and waveform, ...

Abstract

The invention relates to a frequency control circuit, in particular to an eye-protection lamp frequency control circuit. The circuit of an eye-protection lamps bought in a market is poor in reliability, unstable in work, hard to maintain, and higher in cost, and eye-protection efficiency is affected. A controller is arranged on the eye-protection lamp frequency control circuit. A power source input circuit, a high-frequency output circuit, a coding circuit, and a frequency display circuit are arranged on the controller. A load lighting circuit is connected with the high-frequency output circuit. The power source input circuit is connected with the high-frequency output circuit. The model of the controller is PICI3F73. The eye-protection lamp frequency control circuit is characterized by being stable in work, adjustable in work frequency and power, and low in cost. The eye-protection lamp frequency control circuit can realize a variety of frequency control, adapt to a variety of eye-protection lamps and energy-saving lamps, and widely replace a variety of fluorescent lamp controllers.
