High-power LED lights and conventional high-pressure sodium lamps

Countries to actively promote the implementation of energy-saving emission reduction projects, particularly in China's LED lights have been affected due to the huge business opportunities for LED lamp manufacturers attention. Lighting is an important component of urban lighting the traditional lamp often used high-pressure sodium lamp, high pressure sodium lamp as a whole polish the shortcomings of low efficiency resulted in an enormous waste of energy, therefore, the development of new high efficiency, energy saving, long life, high color-rendering index, and environmental protection The lights of the city of great significance to energy-efficient lighting.

Today LED lamp features:

High-power LED lights and conventional high-pressure sodium lamps is different is that high-power LED street lamp light source using low-voltage DC power supply from the power-type GaN-based blue LED and yellow phosphor synthesis of highly efficient white light diodes, light emitting diodes (LightEmittingDiode, abbreviated as LED) is based on the formation of semiconductor PN junction will be able to use the weak energy efficient light-emitting solid-state light sources, in a certain forward bias voltage and injection current, the injection hole and into the P region N region have spread to the electron the source zone is issued by the radiative recombination photons, the energy directly into light.
