Lighting Technology: Solid State and Induction
Lighting is accomplished by a variety of technologies coming together, from light sources to fixtures and controls. EE Green offers both solid state and induction lighting, and retrofit products. As part of our due diligence to customer service, we feel that it is important to inspect and research each manufacturing facility to ensure that you're getting a quality lighting product.
What is Solid State Lighting?
Solid state lighting is an exciting and quickly emerging technology which provides significant cost savings. This type of lighting uses highly efficient long-lasting white LEDs that reduce energy consumption by anywhere from 50% - 80%.
Solid state lighting includes various applications that use light-emitting diodes (LEDs), organic light-emitting diodes (OLEDs), or light-emitting polymers. Instead of using filaments and gases inside a glass bulb like fluorescent or incandescent lighting, solid state lighting uses semiconductors that convert electricity into light. LEDs have been used for over 40 years, but mainly just in indicator lights or for backlighting electronics.
What is Induction Lighting?
Although they look somewhat similar, induction lamps are not the same as fluorescent. They differ in the way they energize mercury atoms inside the bulb. Instead of striking an arc between electrodes in a tube, an electromagnetic field is generated by a carefully shaped coil. The field created by the coil induces a current flow in the gas/mercury blend within the lamp. This current excites the mercury atoms and starts the flow of photons. Mercury atoms emit UV photons; phosphors lining the lamp wall absorb the UV photons and in turn emit visible photons.
Induction lighting has become a popular choice because of its extremely long life span. Induction lamps have no electrodes, so they can last as long as 100,000 hours (10x longer than a fluorescent bulb; 100x longer than an incandescent bulb!). Induction lamps also have high lumen output. Both benefits are ideal for applications with difficult access such as parking garages, street lighting or warehouses where maintenance and replacement can be difficult, costly, or hazardous. Another benefit is low starting temperatures, which is great for freezers or cold storage.
