Led Lamps Technology
Electronic Lighting Science, Inc. (ELS) is one of few vertically integrated LED manufacturers and suppliers in the world. ELS’s LED and products are the next generation in solid state lighting materials. Our LED emitters and products combine highly efficient materials that allow our products an efficacy well above other leading brands in the marketplace. ELS’s LED products are thoroughly tested for conformity and electrical specifications. Our high brightness LEDs are useful in a wide range of lighting applications such as general illumination, automotive lighting, aeronautical lighting applications, and LCD backlighting.
LEDs – How do they work?
When a light-emitting diode is forward biased (switched on), electrons are able to recombine with holes within the device, releasing energy in the form of photons. This effect is called electroluminescence and the color of the light (corresponding to the energy of the photon) is determined by the energy gap of the semiconductor. An LED is often small in area (less than 1 mm2), and integrated optical components may be used to shape its radiation pattern. LEDs present many advantages over incandescent light sources including lower energy consumption, longer lifetime, improved robustness, smaller size, faster switching, and greater durability and reliability.
Physics of LED
Like a normal diode, the LED consists of a chip of semiconducting material doped with impurities to create a p-n (positive and negative) junction. As in other diodes, current flows easily from the p-side, or anode, to the n-side, or cathode, but not in the reverse direction. Charge-carrierselectrons and holesflow into the junction from electrodes with different voltages. When an electron meets a hole, it falls into a lower energy level, and releases energy in the form of a photon.
The wavelength of the light emitted, and thus its color, depends on the band gap energy of the materials forming the p-n junction. In silicon or germanium diodes, the electrons and holes recombine by a non-radiative transition which produces no optical emission, because these are indirect band gap materials. The materials used for the LED have a direct band gap with energies corresponding to near-infrared, visible or near-ultraviolet light.
ELS MR16 LED Lamp
Our MR16 Bulb is a direct replacement for halogen based MR16 bulbs in the marketplace today. Our MR16 consumes only 5 watts. This replacement can reduce your energy consumption up to 90% of your current use.
Our product utilizes a single chip design that eliminates a shadowing effect, giving you clean crisp light output.
