LED lamp development history and use
Jun 20, 2017


In half a century ago, humans have mastered the basic principles of light that can produce light. In 1960, the diodes began to commercialize. The core of the light-emitting diode is composed of p-type semiconductor and n-type semiconductor chip, between the p-type semiconductor and n-type semiconductor has a transition layer, known as p-n junction. In some semiconductor materials PN junction, the injection of minority carriers and the majority of carrier recombination will be the excess energy in the form of light released, so that the power directly into light energy. PN junction plus reverse voltage, a small number of carriers is difficult to inject, so do not light. The use of injection-type electroluminescence principle of the manufacture of the diode called light-emitting diodes, known as LED.

When it is in the positive working state (that is, plus the forward voltage at both ends), the current flows from the LED anode to the cathode, the semiconductor crystal from the ultraviolet to infrared different colors of light, light intensity and current. High-power LED lights with low light failure, high luminous efficiency, widely used in street lamps, fluorescent lamps, spotlights, miner's lamp, tunnel lights and many other lighting areas, the industry was well received.

1. The use of solid-state semiconductor device chip self-encapsulation luminous efficiency, 1W brightness can achieve the effect of ordinary fluorescent 3W, saving 60% of the electricity, with good light failure performance, high temperature pc plastic material refining.

2. The lens is handled by a special method to ensure that it will not fall.

3. Lower vf value (3.1v-3.5v), can reduce the power consumption to reduce heat, extend the LED working hours.

4. The original epoxy resin encapsulation process in the form of electronic energy, white and warm white lumen value can be done almost no product color circle, high color, good consistency.

5.LED lamp life of up to 100,000 hours High brightness, low heat Environmental protection LED lights are made of non-toxic materials, unlike fluorescent lamps containing mercury can cause pollution, while LED lights within the LED material can also be recycled.
