Understanding How LED Lights Work

An Intro to LEDs

The term– Light Emitting Diode (LED) can be broken down into 2 components in order for us to understand it.


Firstly, a diode is an electric part with 2 electrodes whereby electric energy streams. Referred to as an anode and a cathode, electric current circulates in one way in through the anode and out through the cathode.

Made from silicon or selenium which are semi-conductive materials, LEDs have excellent adaptability. Their materials are able to facilitate electric energy in certain conditions such as when at certain voltages, light magnitudes or existing levels.

Light Discharging

Second of all, when put under the context of light discharging, the diode emits light when an adequate degree of electrical energy goes through it.

When a voltage source is linked to both the positive terminal of the anode and the negative terminal of the cathode, this electric current is provided. At this moment, current flows via a microchip that consequently illuminates tiny source of lights to develop visible light.

Light Directional Discharge

Unlike incandescent or fluorescent lighting, LEDs discharge light in a specified direction. This means that through configuration, the LED light can direct the majority of all light produced in the intended direction. This ensures an efficient operation with less wasted energy consumed.

The directional light capability differentiates LEDs from its counterparts such as incandescent or fluorescent lighting which emit equal light in all directions.

Heat Discharge

LEDs take care of created heat by utilizing heat sinks to absorb and dissipate them to the surrounding atmospheres. This assists to keep the LED from overheating or burning out. Given how much lights are used and the equivalent heat generated from them, good heat management is essential for ensuring a good lifespan.

In contrast, other lighting products that are unable to deal with produced heat will start to suffer from wear and tear. The heat produced affects the quality of the materials and components, which eventually will lead to a drop in light production efficiency.

Combining Light & Heat Efficiency

When both light and heat efficiency are combined, you can see why in the long run, LED Light Installation would offer major expense savings. In fact, LED lights have an average lifespan of as much as 50,000 hours and a forecasted light output depreciation by 30% after that point. As such, you can expect that LED lights would last for 2 to 3 times longer than fluorescent bulbs and over 50 times greater than incandescent bulbs. 

Along with bonus life-span from heat control, LEDs also enjoy raised sturdiness. They have the ability to stand up to greater levels of vibration and shock that may come about in aged electric circuits.
