Description
Technical field
The utility model relates to a kind of desk lamp, especially relates to a kind of study eye-protecting desk lamp.
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, the light efficiency height, the life-span is long, high-brightness LED be the mankind behind Edison's utility model incandescent lamp bulb, one of greatest utility model; 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 regulate according to light automatically, be not with the use prompting function, long-time use makes eye fatigue easily, even myopia, the following photochromic relatively nature of desk lamp colour temperature 5500K and do not hinder eye, the light source of environment also can influence, if environment light source is not enough, 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 for use the colour temperature of 4000K～5600K.
The utility model content
The technical problems to be solved in the utility model provides a kind ofly can regulate brightness automatically according to light intensity, the study eye-protecting desk lamp of band time reminding function.
The technical scheme that its technical problem that solves the utility model adopts 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 first photo resistance on the lamp body panel and being located at and deviate from light source shadow surface position on the lamp body for detection of 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, the described second photo resistance operational light sensor for detection of ambient light replaces.
Use the study of the utility model 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 controller resistance value that detects first photo resistance and second photo resistance is stored;
6. when ambient light brightness changed, the resistance value of second photo resistance changed, and controller is regulated light source output power automatically;
7. after reaching the Preset Time value service time, controller is reminded the user;
8. after finishing using, touch power supply switch controller and enter holding state;
9. touch power supply switch controller again and return 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 control output PWM waveform, the current value of the different sizes of control light source drive IC output, realize regulating light-source brightness, make the colour temperature control of light at 4000K ~ 9000K, best color temperature value 6500K ± 200K.
The utility model is simple in structure, realizes that the adjustable brightness scope of light is wide easily, and colour temperature is controlled, the band prompting function.
