Made popular by their efficiency, range of color, and long lifespan, LED lights are ideal for numerous applications including night lighting, art lighting, and outdoor lighting. These lights are also commonly used in electronics and automotive industries, and for signage, along with many other uses.
Applications and Uses of LEDs can be seen in:
Smartphone Backlighting. LED displays. Automotive Lighting. Dimming of lights.
Recent LED Technology
In their place are DC LED chips that handle all the power requirements for the LED directly on the chip. This allows more compact packaging and a host of new product applications. Additionally, light output relative to cost continues to increase across the industry.
LED Colour
The light emitted by normal LED bulbs comes in three different varieties which are: Warm white which is used in most homes and is similar to current halogen bulbs. Cool white is a similar colour to fluorescent tubes such as those you find in shops and offices.
Advantages of LED Lights
In the simplest terms, a light-emitting diode (LED) is a semiconductor device that emits light when an electric current is passed through it.
What are the disadvantages of LEDs?
LEDs must always be connected in series with a resistor. LEDs are diodes which means that current can only flow through an LED from the anode to the cathode and not the other way around.
What should be the biasing of the LED? Explanation: The LED works when the p-n junction is forward biased i.e., the p- side is connected to the positive terminal and n-side to the negative terminal. 6.
