Description
Technical field
The present invention relates to a kind of desk lamp, especially relate to a kind of study eye-protecting desk lamp and control method thereof.
Background technology
along with the raising day by day of living standard, the LED electricity-saving lamp is slowly come into people's life, low-power consumption, light efficiency is high, the life-span is long, high-brightness LED be the mankind after the Edison invented incandescent lamp bulb, one of greatest invention, desk lamp light source is in the market mainly used incandescent lamp, electricity-saving lamp and LED lamp, switching regulator or manual adjustments mode, exist light intensity and soften can not regulate or regulating effect undesirable, can not automatically regulate according to light, be not with the use prompting function, long-time use easily makes eye tired, even near-sighted, the following photochromic relatively nature of desk lamp colour temperature 5500K and do not hinder eye, the light source of environment also can affect, if environment light source is inadequate, that just thinks easily that the light of desk lamp crosses bright with dazzling, sedate, quiet people is fit to select the colour temperature of 6500K～9000K, and ebullient people is suitable for selecting the colour temperature of 4000K～5600K.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of can be according to the light intensity automatic regulating lightness, with the study of time reminding function with eye-protecting desk lamp and control method thereof.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of study eye-protecting desk lamp, comprise lamp body, light source, power switch, controller, it is characterized in that: also comprise being installed on the first photo resistance on the lamp body panel and being located at and deviate from light source irradiation face position on lamp body for detection of the second photo resistance of ambient light.
Further, described controller comprises single-chip microcomputer, light source drive IC, button, buzzer and peripheral circuit thereof.
Further, described power switch adopts contact electrode or touch capacitance sensor.
Further, described the second photo resistance operational light sensor for detection of ambient light replaces.
Use the present invention's study with the control method that eye-protecting desk lamp carries out brightness regulation to be:
1. initialization controller;
2. detect the second photo resistance resistance and obtain the ambient light brightness value;
3. power is preset in the output of controller output PWM Waveform Control light source drive IC;
4. the user regulates light source output power to the light luminance that needs;
5. the resistance value of controller detection the first photo resistance and the second photo resistance is stored;
6. when ambient light brightness changed, the resistance value of the second photo resistance changed, and controller is regulated light source output power automatically;
7. after reaching the Preset Time value service time, the controller reminding user;
8. after finishing using, touch power supply switch controller and enter holding state;
9. again touch power supply switch controller and return to 2. step execution.
Its operation principle is: light source luminescent intensity is carried out AD by the variation of the first photo resistance resistance by controller and is gathered magnitude of voltage, controller is controlled output PWM waveform, control the current value of the different sizes of light source drive IC output, realize regulating light-source brightness, make the colour temperature of light be controlled at 4000K ~ 9000K, best color temperature value 6500K ± 200K.
