Tashqi projektörlarning xiralashtirish rejimining afzalliklari, kamchiliklari va kelajakdagi rivojlanishini tahlil qilish
Anyone who has known externally controlled LED floodlights knows that the general control mode is to use the 512 controller to control the lighting program, but with the development of technology, there are other modes that can be realized. Of course, the 512 control mode is more commonly used. Next, Ruiyi Lighting will show you what other dimming modes?
Usullardan biri LEDning harakatlanish oqimini sozlash orqali LED chiroqning xiralashishini amalga oshirishdir, chunki LED chipining yorqinligi va LEDning harakatlanish oqimi qat'iy nisbatga ega.
Ikki usul: Karartma odatda analog karartma rejimi yoki chiziqli karartma deb ataladi. Ushbu karartmaning afzalligi shundaki, qo'zg'alish oqimi chiziqli ravishda oshganda yoki kamayganda, LED chipi nisbatan kamayadi va boshqaruv pallasida harakatlantiruvchi oqimning haddan tashqari oshib ketishi ta'siriga kuchli immunitet mavjud. Kamchilik shundaki, harakatlanish oqimining o'zgarishi LED chipining rang haroratiga ma'lum ta'sir ko'rsatadi.
Xiralashtirishning uchinchi usuli - bu Pulse Light Modulator (PWM) rejimi. Bu usul ma'lum bir boshqaruv orqali harakatlanish oqimini kvadratga aylantirishdir va zarba kengligi o'zgarishi mumkin. Pulsning kengligini sozlash orqali energiya tejash maqsadiga erishish uchun vaqtni o'zgartirish va chiqish quvvatini bir vaqtning o'zida o'zgartirish mumkin. Chastotani o'zgartirish tezligini tartibga solish odatda 200Hz va 10kHz oralig'ida. Inson ko'zlari zahiralanganligi sababli, odamlar yorug'likning miltillash jarayonini his qila olmaydi. Ushbu yondashuvning afzalligi shundaki, yorug'likni harakatlantirish LEDning issiqlik tarqalishini yaxshilash afzalligiga ega. Kamchilik shundaki, haydovchi oqimining haddan tashqari oshib ketishi LED chipining ishlash muddatiga ma'lum ta'sir ko'rsatadi.
The above three dimmer methods are classified according to the output control of the drive current of the LED. The control circuit can also be divided into analog control and PWM control, the control circuit is usually completed by a microcontroller.
In the field of road lighting, the application of LEDs is spreading rapidly, and long life and reliability are still the key things to be considered, but with the development of technology, when the problems of life and reliability are solved, to a certain extent, LED lighting applications Programs will inevitably move towards the pace of intelligent dimming systems. The perfect intelligent control of LED flood light should have manual control, intelligent control, light control, time control and fault alarm functions. When the sun goes down, the sky can be automatically turned on, and the lights at 12:00 midnight can be automatically halved; after dawn, the light can be automatically turned off; in special cases, people can manually control; when the control fails, the control system can automatically Call the police.
