Background technology
The common feature of common various lamp dimmer circuit is on the market: the brightness of desk lamp must be passed through manual adjustment, and desk lamp itself can not be regulated the brightness of light automatically along with the variation of surrounding environment brightness.
Light operated desk lamp of the present invention can be according to the luminous quantity of the strong and weak adjustment automatically of surrounding environment illumination desk lamp.When the illumination of ambient light was more weak, the luminosity of desk lamp will increase automatically; When the ambient light illumination grow, the deepening automatically of the luminosity of desk lamp.The present invention had both removed the trouble of manual light modulation from, can protect the eyesight of eyes again, can also stop unnecessary power wastage effectively.
It is simple that this desk lamp has a circuit, all uses common components and parts, and cost of manufacture only needs tens yuan, is well suited for exploitation in batches, also is suitable for the novel reading lamp that factory's exploitation has automatic control illumination function.
Through kinds of schemes test, relatively and analyze, the present invention only uses a small amount of common discrete component, has realized that circuit structure is simple, cost is low, designing requirement such as effective, reliable working performance.
Below specify this Light operated desk lamp related relevant technologies content in manufacturing process.
Summary of the invention
Goal of the invention and beneficial effect: Light operated desk lamp of the present invention can be according to the luminous quantity of the strong and weak adjustment automatically of surrounding environment illumination desk lamp.When ambient lighting was more weak, its luminosity will increase automatically; When the ambient lighting grow, the deepening automatically of desk lamp luminosity.The present invention had both removed the trouble of manual light modulation from, can protect the eyesight of eyes again, also helped the saving unnecessary power consumption.It is simple that this desk lamp has a circuit, all uses common components and parts, and cost of manufacture only needs tens yuan, is well suited for exploitation in batches, also is suitable for developing the novel reading lamp with automatic control illumination function.
Technical characterictic: Light operated desk lamp, to form by AC power, incandescent lamp, full bridge rectifier, controllable silicon and circuits for triggering thereof, light-operated circuit, its characteristic comprises:
Full bridge rectifier: be connected into full bridge rectifier by 4 silicon rectifier diode D1～D4; Connect the input of full bridge rectifier behind the live wire end L of the AC power serial connection incandescent lamp HL respectively with the zero line side N of AC power; The anodal VCC of the cathode output end connection circuit of full bridge rectifier, the cathode output end connection circuit ground GND of full bridge rectifier;
