Description
Technical Field
The invention relates to a lighting system, in particular to a lighting system capable of automatically adjusting illumination intensity.
Background
The bulb is made based on the thermal effect principle of current, refers to an illumination source which emits light and heat by electric energy, and is invented by henry and gobier. The "lighting device" is produced with the development of human civilization, and the most common function of a bulb is lighting. With the development of society, the use of bulbs has been changed variously, and it is possible to provide convenience for production and life at first, but with the progress of society, the use of bulbs has also been changed remarkably, and functional lamps for various purposes such as "automobile, environment beautification, decoration" and the like have been started.
The social development is higher and higher to people's requirement to light so far, and traditional lighting system can change because of the change of voltage, and too high low of voltage can lead to the lamp to turn off too bright or too dark to hurt people's eyes, influence eyesight.
Disclosure of Invention
The invention aims to provide an illumination system capable of automatically adjusting illumination intensity, and solves the problems that a traditional lighting system changes due to the change of voltage, and the over-high and over-low voltage can cause the over-bright or over-dark of a lamp switch, so that eyes of people are injured and the eyesight is influenced.
The invention is realized by the following technical scheme:
illumination system that can automatically regulated illumination intensity, including controller, optoelectronic coupler, bulb, power, first variable resistance, compensation unit, power and optoelectronic coupler are connected to the input of controller, and first variable resistance is connected to the output of controller, compensation unit connects between controller and bulb, the controller is 51 singlechips, be provided with compensation power and second variable resistance in the compensation unit, the controller is being connected to second variable resistance.
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 changes, the photoelectric coupler senses the change of the illumination intensity, the illumination intensity at the moment is converted into a current signal and is conducted to the controller, the controller readjusts the first variable resistor to recover the brightness of the bulb, and the problems that the traditional light system changes due to the change of the voltage, the overhigh voltage and the overlow voltage can cause the overlow or overlow lamp to be turned off, the eyes of a person are injured, and the eyesight is affected are solved.
Further, the first variable resistor and the first variable resistor are both resistor boxes. The resistance box facilitates the control of the controller on the resistance size.
Compared with the prior art, the invention has the following advantages and beneficial effects:
1. the lighting system can automatically adjust the illumination intensity, and solves the problems that the traditional lighting system can change due to the change of voltage, and the over-high and over-low voltage can cause the over-bright or over-dark of the lamp switch, thereby injuring the eyes of people and influencing the eyesight;
2. the illumination system can automatically adjust the illumination intensity, has good control performance and is low in price;
3. the illumination system can automatically adjust the illumination intensity, is convenient to control and has strong stability.
Drawings
The accompanying drawings, which are included to provide a further understanding of the embodiments of the invention and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the invention and together with the description serve to explain the principles of the invention. In the drawings:
FIG. 1 is a schematic diagram of the system of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to examples and accompanying drawings, and the exemplary embodiments and descriptions thereof are only used for explaining the present invention and are not meant to limit the present invention.
Examples
As shown in fig. 1, the illumination system capable of automatically adjusting illumination intensity of the present invention includes a controller, a photoelectric coupler, a bulb, a power supply, a first variable resistor, and a compensation unit, wherein an input end of the controller is connected to the power supply and the photoelectric coupler, an output end of the controller is connected to the first variable resistor, the compensation unit is connected between the controller and the bulb, the controller is a 51-chip microcomputer, a compensation power supply and a second variable resistor are disposed in the compensation unit, the second variable resistor is connected to the controller, and both the first variable resistor and the first variable resistor are a resistor box.
The controller controls the first variable resistor to adjust the light to a comfortable brightness, when the power supply voltage changes, the bulb brightness changes, the photoelectric coupler senses the change of the illumination intensity, the illumination intensity at the moment is converted into a current signal and is conducted to the controller, the controller readjusts the first variable resistor to recover the bulb brightness, when the power supply voltage is too small, the controller adjusts the second variable resistor, the compensation power supply compensates the voltage to recover the voltage to an original value, the stability of the bulb brightness is ensured, and the problems that the traditional light system changes due to the change of the voltage, the lamp is too bright or too dark due to too high or too low of the voltage, the eyes of people are injured, and the eyesight is affected are solved.
The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are merely exemplary embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
