Around 30-40% of the non-directional light emitted through a fluorescent bulb is wasted. This much light gets lost to various refractions or diverted to an area where it is not required. MostLED lightingoptions are directional. Thus, you can direct the light in any direction that you need ...
A power converter is added to a fluorescent light to inexpensively convert fluorescent lighting to LED lighting utilizing existing ballast technology. This will encourage and facilitate conversion to more efficient lighting and the result will be energy savings. The conversion is relatively inexpensive ...

A lamp that produces light by exciting the atoms of a mixture of argon gas and mercury vapor with electric current. Ultraviolet rays produced by the excited atoms strike a phosphor coating on the interior surface of the bulb, causing it to emit visible light. Fluorescent lamps are much more ...
From optimized energy efficiency to the highest light output. Now you can find the right energy efficient tube lights with the Philips LED tube light portfolio.
A phosphor is then used to convert the UV to visible light, resulting in a total conversion efficiency of electrical power to visible light of about 25%. Figure 15 is a schematic diagram illustrating the major components of a conventional linear fluorescent lamp. These lamps are typically long ...
Phototherapy for Neonatal Jaundice: in Vitro Comparison of Light Sources Phototherapy results in the conversion of to more -soluble isomers. Six clinically used phototherapy lamps which differ in their emission spectra have been compared in their ability to produce configurational and structural isomers ...

In recent years, the light-emitting diode (LED) has become a new lighting source for poultry production. LED provides longer life span, better energy efficiency, and selectable light spectra that conventional lighting (such as fluorescent, FL) does not, which attracts more producers to adopt LED...
The invention relates to a fluorescent powder coating process for a light-emitting diode (LED) optical lens and an encapsulation process for a white light LED with the optical lens, and relates to a fluorescent powder coating process and an encapsulation process, which solve the problems of non...
