Fu Manwei PWM moves smooth blame to keep apart IC of drive of step-down constant current
Fu Manwei’s PWM moves smooth blame to keep apart IC of drive of step-down constant current is it is important that one kind is used at LED illume pilot chip.
This kind of chip has the following characteristic and advantage:
- Tall efficiency changes: Can change input voltage efficiently the constant current output that is stability, reduce energy loss.
- The electric current with accurate essence controls: Ensure LED glow is stable, avoid to twinkle with brightness not all.
- PWM moves smooth function: Through adjusting pulse width realizes the accurate control of pair of LED brightness, provide the flowing result that move light.
- Be not segregation step-down design: Reduced cost and circuit complex degree, reduced the volume of integral plan.
- Limits of wide input voltage: Get used to different power source to input a condition, increased applied flexibility.
- Good heat manages: Send out effectively the quantity of heat of the generation when chip works, ensure the stability of chip and dependability.
- Compatibility is strong: Can match with the LED load of a variety of different types and norms.
In applying actually, it is commonly used wait for a domain at indoor illume, commerce illume, outdoors illume, to come true high quality, adjustable the technical support that LED illume effect provided a key.
IC of drive of constant current of step-down of segregation of smooth blame of attune of Fu Manwei PWM can apply at many more the following domain:
Indoor illume:
- Domestic illume: Wait like droplight, desk lamp, wall lamp, can realize brightness adjustment according to different setting and demand.
- Office lighting: The desk lamp of the office, ceiling light, get used to different working pattern and environmental brightness.
Commercial illume:
- Bazaar shop: Use at revealing ark illume, shop interior illume, build easy shopping environment.
- Hotel: The lamplight of the area such as guest room, corridor, banqueting hall is controlled, satisfy the illume requirement of diversification.
Outdoors illume: Street lamp: Implementation is energy-saving with brightness adjustment, get used to different time paragraph traffic discharge and environmental brightness. Offer agile lighting effects for the landscape such as park, square.
Car illume: The illume inside the car: Include lamp of appearance dial lamp, the atmosphere inside the car to wait.
Industrial illume: Factory workshop: Offer appropriate illume brightness to produce section, enhance work efficiency and security.
Indication screen is in a poor light: Of liquid crystal indication screen be in a poor light control, provide even brightness and adjustable contrast.
Advertisement illume: The illume that wait controls box of billboard, lamp, draw attention and energy-saving.
Intelligent lighting system: As compositive as intelligent household or intelligent architecture system, realize illume of automation and long-range pilot to adjust.
