[0018] Example

[0019] Such as figure 1 As shown, the present invention can maintain a stable light intensity lighting system, including a controller, a photocoupler, a bulb, a power supply, a first variable resistor, and a compensation unit. The input of the controller is connected to the power supply and the photocoupler to control The output terminal of the device is connected to the first variable resistor, the compensation unit is connected between the controller and the bulb, the controller is a 51 single-chip microcomputer, and the compensation unit is provided with a compensation power supply and a second variable resistor. The second variable resistor is connected to the controller, and the first variable resistor and the first variable resistor are both resistance boxes.

[0020] In the present invention, the controller controls the first variable resistor to adjust the light to a comfortable brightness. When the power supply voltage changes, the brightness of the bulb ...

Abstract

The invention discloses a lamplight system capable of maintaining stable illumination intensity. The system comprises a controller, a photoelectric coupler, a lamp bulb, a power source, a first variable resistor and a compensation unit; the input ends of the controller are connected with the power source and the photoelectric coupler; the output end of the controller is connected with the first variable resistor; and the compensation unit is connected between the controller and the lamp bulb. According to the lamplight system of the present invention, the first variable resistor is controlledthrough the controller so as to adjust lamplight to a comfortable brightness; when the voltage of the power source changes, the brightness of the lamp bulb changes correspondingly; the photoelectric coupler senses the change of illumination intensity, converts illumination intensity at this moment into current signals, and transmits the current signals to the controller; and the controller re-adjusts the first variable resistor, so that the brightness of the lamp bulb recovers. A traditional lamplight system will change with the change of voltage, excessively high or low voltage will lead to excessively bright or dark lamplight, and as a result, the lamplight will harm the eyes of people and affect the eyesight of the people, while, with the lamplight system of the invention adopted, the situation in the prior art can be solved.

Description

technical field [0001] The invention relates to a lighting system, in particular to a lighting system capable of maintaining stable light intensity. Background technique [0002] The light bulb is made according to the principle of the thermal effect of electric current. It refers to the lighting source that emits light and heat through electric energy. It was invented by Henry Goebbels. "Lighting appliances" are produced with the continuous development of human civilization, and the most common function of light bulbs is lighting. With the development of society, the use of light bulbs has also undergone different changes. At first, it may be for the convenience of production and life, but with the progress of society, there have been obvious changes in the use of light bulbs. Functional lamps for different purposes such as "environment, decoration". [0003] With the development of society, people have higher and higher requirements for lighting. The traditional lighting...
