What is LED?

LEDs (light emitting diodes) are solid-state semiconductor devices that can convert electrical energy directly into light. The heart of a led is a semiconductor chip of which one side is attached on the top of an anvil that is the negative power lead, and the other side is connected with a whisker to a positive power lead. it is the most important part of the LED. and it is entirely encapsulated in an epoxy resin enclosure.

Features and Benefits of LED

The inherent features of LED is decidedly the ability of LED to become the best alternative to conventional light sources, and provide a wider range of applications.

Small Size

An LED is essentially a microscopic chip once encapsulated in an epoxy resin are extremely small and lightweight.

Low power consumption

LED consume very little power, far less than standard light bulbs leading to greatly reduced energy costs and extremely enhanced global energy savings.

LEDs also require far less energy to manufacture than other light sources, reducing the environmental impact of artificial lighting even further. Generally a LED is designed to operate at 2 - 3.6V, 0.02-0.03A current which means a LED typically requires no more than 0.1W to operate.

Long Lifetime

When operating at specified voltage, current, and within specified environmental conditions, LEDs can enjoy a long life of up to 100,000 hours. A newer way to evaluate LED lifetime has been established and adopted by Neo-Neon which is based on lumens depreciation over time to determine the Mean Time between Failure (MTBF).

High Luminous Efficiency and Low heat Emitting

Due to the special materials that are used to manufacture LEDs during electrons transition, LED’s mainly emit electromagnetic energy in the visible parts of spectrum. This is unlike incandescent fi laments which are heated and emit large amounts of electromagnetic energy in the infrared spectrum which can’t be seen and is felt as heat. That is to say, LEDs can convert significantly more of the energy applied into light, and therefore LEDs have a higher luminous efficiency with substantially lower amounts of heat produced.

Environmental Protection

LEDs are made from non-toxic materials, unlike fluorescent lights that contain mercury which poses a danger to the environment and human health.
