LED is the English light emitting diode (LED) acronym, and its basic structure is an electroluminescent semiconductor material, placed in a wire rack, then sealed with epoxy resin around, protect the internal core wire effect, so the seismic performance LED.
a light-emitting LED structure and principles of
50 years ago, people have to understand the semiconductor material can produce light of the basic knowledge, the first commercially available diodes in 1960. The core part of the light-emitting diode is a p-type semiconductor and n-type semiconductor chip formed in the p-type semiconductor and n-type semiconductor between a transition layer, called the pn junction. In certain semiconductor materials, PN junction, the injection of minority carrier and majority carrier recombination, when will the excess energy released in the form of light to convert light energy directly into electrical energy. PN junction reverse voltage, minority-carrier injection is difficult,it is not light.

Matters Needing Attention
1. The light’s waterproof grade is IP65, able to withstand rains, but it can’t work under water.
2. Cut off power supply before and in installation process. If the product is damaged due to mal-operation, it shall not be guaranteed. Please have it mounted by a professional.
3. The light’s operating ambient temperature is between -25℃ and 45℃. The temperature of operational site shall not exceed 45℃, to ensure the light’s service life.
4. Since the light power is high, when power line is arranged, it’s necessary to select a proper power line according to actual power, and supply power in single phase.
5. Please don’t dismount the light without authorization. Please contact professional maintenance personnel or the manufacturer if the light isn’t lit or is faulty otherwise.
