As LED technology develops and new solutions appear on the market nearly every week, it is getting more difficult to find out which solution is the best for your applications and most importantly, what features you have to pay attention to during purchase. LED circuits are made of whiskers which remain connected to the anode. LEDs are highly sensitive to changes both in voltage and current, so if you are dealing with low voltage LED lights, wire-wound, stabilized transformers are the safe solution.
There are three components matter in the operation of LED lights: voltage, current and heat. Constant current circuits are especially safe for high power LED lights, as they are suitable for 24/7 operation. If the LED light is provideded with constant current circuit, the current is fixed by the stabilized transformer and does not generate further heat within the LED light. LEDs are highly sensitive to a change in all three of these, so their regulation is very important for gaining a long lifespan. Current is often looked at as an exponential function of voltage, therefore even a small volume of change in voltage can result in a large change in the current. However, current load can also increase with the increase of heat. To avoid overloading, LEDs are driven from low voltage DC via a current limiting resistor or constant current regulators. Another additional solution is the cooling of the LEDs with heat sinks. Not all of the LEDs are attached to heat sinks, which is why the limitation on the hours of application is so important.
So, when you are going to purchase the LED light, you have to know something before shopping. Firstly, you must know the initial cost of installing them is normally high. But for long-term good, the LED can replace any extra costs if you use the traditional bulbs, which might costs you more on buying new bulbs. Second of all, you have to supply the lights functional constant current driver if you install the lights at home. With the good constant current driver, you will experience the better light since it won’t flicker or a continuous basis. Thirdly, LED can help you save electricity because the LED lights are monochromatic, which is the source of power supply. So, you don’t have to worry about the wastage of the energy. But LED light itself doesn’t provide too many colors for the users, as well as the brightness. LED performs well when focusing on something rather than make the whole room bright enough as you except.
