Basic knowledge of LED tube Routine parameters and meanings, explaining the main structure, introducing occasions, introducing customers concerns and concluding remarks Introduction to conventional photoelectric color parameters Power is the measure of energy transfer rate, it is in the DC voltage V and current A and the product, namely W=UI? The power factor of the power factor is equal to the actual power and the ratio of apparent power (sinusoidal alternating current circuit, the voltage effective value of product and the effective value of the current is called apparent power), as in power), apparent power), its unit is why cant PF. the power factor reached 1, because there is a part of the reactive power in the power storage capacitor, it can ensure the normal operation of the circuit. The input voltage is the voltage required for LED to work, around the world according to different countries and different values of input voltage, we usually refer to the total voltage is AC85V~265V, our sales of LED lighting is now the input voltage of the 220V in the country, Japan is 100V voltage, 230V~240V voltage is USA Malaysia, is also great the difference between 112V120V and so on according to different input voltage region. When the color of the light emitted by the color temperature source is the same as that of the blackbody at a certain temperature, the temperature of the blackbody is called the color temperature of the light source. In K (Kelvin, or Kelvin temperature) as a unit (K=, +273.15). Therefore, when the blackbody is heated to red, the temperature is about 527 DEG C, or 800K, Cold white, white, warm white difference: warm white is about 3000K, white is about 6000K, cold white is more than 6500K. Following chart: The luminous flux emitted by a light source with a radiation and by all hum
