LED floodlight single lamp and COB integrated lamp, LED light which is better?
A single lamp is certainly good, but the price is expensive. The concept of integration on the market is not very mature, and the integrated chip has just come out, it is only a point of purchase, no technical advantage. General good LED did not integrate, Samsung Ge A Corey has not seen integrated in the country
Each lamp used in different places, the effect will be better, the general light is a single high-power production, while most of the integrated use of floodlights.
The terminal voltage of PN junction constitutes a certain barrier. When the forward bias voltage is applied, the potential barrier decreases, and the majority carrier in the P region and the N region diffuse to each other. Since the electron mobility is much larger than the hole mobility, a large amount of electrons will diffuse into the P region, which will result in the injection of minority carriers into the P region. These electrons are combined with holes in the valence band, and the energy is released in the form of light energy when combined. This is the principle of PN junction luminescence.
Sure is a single lamp.The integrated chip just came out later, not just a buy point, no technical advantage, the general good LED is not integrated.
