LED’s (Light Emitting Diodes) are solid-state semiconductor devices that convert electrical energy directly into light. With the advance of white LED technology applied singularly or in clusters, the arrays are now bright enough to be used for ‘General and Commercial Illumination’. Homes, Offices, Public Buildings, Shopping Centers and all commercial or industrial customers all around the world are applying new WLED based illumination products.
The inherent features of LED is decidedly the ability of LED to become the best alternative to conventional light sources while providing 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 lights bulbs leading to greatly reduced energy costs and enhanced 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 an LED typically requires no more than 0.1 W to operate.
Unbreakable – LEDs are rugged, solid state devices and are not susceptible to vibration such as incandescent filament based bulbs. The LED semi-conductor chip is completely embedded in an epoxy resin enclosure, plus often in ceramic packages and encapsulated with organic phosphors which are much sturdier than traditional glass bulbs and fluorescent tubes. They are solid-state technology thus no loose and moving parts which makes LEDs virtually indestructible.
Long Lifetime – When operating at specified voltage and current within the 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 some of our suppliers. This is based on lumens depreciation and lumens maintenance (LM). These standards have been refined over the past years as well as testing methods to provide consumers with a high degree of confidence in lifetime.
High Luminous Efficiency and Low heat emitting – Due to special materials that are used to manufacture LEDs during electrons transition, LEDs mainly emit electromagnetic energy in the visible parts of spectrum. This is unlike incandescent filaments which are heated and emit large amounts of electromagnetic energy in the infrared spectrum which can’t be seen and is felt as heat. This shows that LEDs can convert significantly more of the energy applied into light, and therefore LEDs have a higher luminous efficiency with substantially lower amounts of produced heat. This gives LEDs the ability to also significantly impact the energy demands of building air-cooling systems thus adding a secondary energy savings benefit.
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. LEDs are recyclable this serves as an important factor in environmental considerations for purchase by most customers.
