Very early that there have been a constant current diode, this diode is not a cause for concern, because it’s just as the current standard for some instrumentation. However, recently led the industry to flourish, these diodes are suddenly aroused widespread interest. Many foreign companies have developed products for driving mains LED lights because the led high bay light must be the reason of the constant current source driven. Here we will be in-depth discussion of the properties and applications of the constant current diode.
The ideal constant current source is an internal resistance for the infinite devices, irrespective of the voltage across the value, the current flows through will never change. Of course, this device could not exist. Constant-current diode is equivalent to a certain operating voltage range (for example, 25-100V), its current is constant for a particular value (eg 20mA).
And high-voltage LED compared discrete low-power mains LED lights. As mentioned earlier, high-voltage LED integrated LED a low-power discrete LED series and high-voltage LED external characteristic. The advantages of discrete LED’s flexibility, users needed the series of any number of LED to get the volt-ampere characteristic. Series and parallel can also be more flexible features. Discrete LED’s emitting surface can adjust (increase) in a certain range, so that luminous uniform, reduce glare. Separation of the mains LED lights heat dissipation area is relatively large, easy to disperse the heat, to simplify the design of the radiator. The integrated high-voltage mains LED lights reduces packaging costs. Integrated high-voltage LED reduce.
