Embodiment Construction

[0014] The present invention will be described in detail below in combination with specific embodiments.

[0015] A fixed frequency controller for an eye protection lamp according to the present invention includes a control circuit 103, a power input circuit 102 and a power output circuit 104 are connected to the control circuit 103, and a power input circuit 101 is connected to the power output circuit 104 It is connected with the lighting circuit 105 ; the first power input circuit 101 and the second power input circuit 102 . The control circuit 103 is a 555 oscillator adjustable circuit.

[0016] The external alternating current passes through the power input circuit 1 and the power input circuit 2 to provide two working power sources respectively. The power input circuit provides working current for the power output circuit 104 through bridge rectification DX1. The power input circuit 2 provides working current for the control circuit 103, that is, the 555 oscillating ad...

Abstract

The invention relates to a fixed frequency controller of an eye-protection lamp. Frequency of eye-protection lamps capable of being purchased in a market is higher and not stable, a circuit effective Q valve is lower, some eye-protection lamps even can not reach the purpose of protecting eyes, the eye-protection lamps are complicated in variety, mutual substitution ability is poor, and the eye-protection lamps bring inconvenience for users to use and maintain. The fixed frequency controller of the eye-protection lamp comprises a control circuit, a power input circuit II and a power output circuit are connected with the control circuit, and a power input circuit I and a lighting circuit are connected with the power output circuit. The power input circuit I is connected with the power input circuit II. The control circuit is a 555 oscillation adjustable circuit. According to the fixed frequency controller of the eye-protection lamp, the 555 oscillation adjustable circuit is adopted, a module circuit is adopted for power rectification, frequency is stable, work is reliable, power efficiency is close to ideal design requirements, the circuit Q value is higher, and the fixed frequency controller of the eye-protection lamp is suitable for mutual substitution of most of the eye-protection lamps.

Description

technical field [0001] The invention relates to a frequency controller, in particular to a fixed frequency controller for an eye protection lamp. Background technique [0002] At present, the eye protection lamps that can be purchased in the market have a relatively high frequency, but the frequency is unstable, and the effective Q value of the circuit is relatively low, and some even fail to achieve the purpose of eye protection. Inconvenience has been caused. Contents of the invention [0003] The purpose of the present invention is to provide a fixed frequency controller for eye protection lamps with more stable frequency. [0004] The technical scheme adopted in the present invention is: [0005] A fixed frequency controller for an eye protection lamp, characterized in that: [0006] The frequency controller includes a control circuit, the control circuit is connected with a power input circuit 2 and a power output circuit, and the power output circuit is connect...
