There are many ways to dimming LEDs. Depending on the application requirements of the system, there are different options. It can be divided into PWM Dimming and Analog Dimming depending on the LED output current waveform. Simply put, the so-called pulse width modulation dimming means that the output current of the LED is a periodic square wave output with LED conduction and LED non-conduction, and the average current of the LED is adjusted by changing the on-time width of the square wave waveform. Size, to achieve the function of dimming. Therefore, the average LED current value can be equal to the on-period of the square wave multiplied by the maximum current, ie ILEDavg = Duty(%) × ILEDmaxAnalog dimming is the output current of the LED is an analog output waveform. By changing the ...

SmartLighting involves communication and sensing functions that enable remote control (turning on or off, dimming or changing colors) and monitoring (remote diagnostics) of one or more fixtures in a building, street or home. Intelligent lighting also provides information to the luminaire so that it can be adjusted for brightness depending on usage or ambient light. On the other hand, high-brightness white LEDs are ideal for area lighting applications, with better directionality, better color quality, and environmental protection, and can be more easily controlled to turn on and off, allowing automatic detection of ambient light to change brightness. It is gaining more and more attention in applications such as smart LED street lights.Intelligent lighting communication can be achieved with ...

Brief analysis of electricity consumption in office buildingsA group of survey figures from relevant state departments show that the total annual electricity consumption of office buildings in China accounts for 10% of the total national consumption, and the energy cost exceeds 80 billion yuan, mainly including government offices, enterprises and institutions, commercial office buildings and other office buildings. Most of the office buildings use more than 100KWH of electricity throughout the year, of which air-conditioning power is 45-50%; users use 35-40% indoor electricity; public electricity expenses 10-15%.At present, most domestic buildings are carried out by administrative means, such as “replacement of lamps”, “turning off lights”, “reducing air conditioning temperature”, etc. The...
