What's the doorway to the LED flood light?
In fact, he is a LED lamp, is made of gallium arsenide, gallium arsenide, AlGaAs and other semiconductors, the conversion of electricity to light energy process.
In fact, LED floodlight is a kind of LED lamp. It is a point light source that can be irradiated evenly in all directions. Its range of illumination can be adjusted at random, and it can be shown as a picture of a positive eight body in the scene. Mainly used for building decoration lighting in commercial space, and lighting, decorative elements heavier, its appearance is round or square, because generally have to consider heat causes, it cast light on its shape and there are some differences between the traditional.
When the forward current is higher, the light emitted by LED is brighter, and the stability of LED emission is also affected by the stability of current. Therefore, the LED constant current source should be selected as far as possible in the application of steady current.
It is mainly composed of N layer formed by N semiconductor, P layer formed by P semiconductor and active layer in the center. When the applied positive bias, P area hole diffusion to the negative direction, into the active region, and electronic N area will spread to the positive direction, into the active region, when the electron and hole combination, will emit light spontaneously. When materials are used differently, light of different colors will be emitted due to different levels of energy, such as red, orange, yellow, green, blue, or invisible light.
1, LED floodlight brightness (MCD) is different, the price is different. The LED for the LED luminaire shall comply with the laser class I standard.2, antistatic ability, antistatic ability of LED, long life, and therefore high prices. Usually antistatic 700V than LED can be used for LED lighting.3, wavelength consistent LED, color consistency, such as the same color requirements, the price is high. It is difficult for manufacturers without LED spectrophotometer to produce pure color products.4, leakage current LED pan light is one-way conductive light, and if there is reverse current, it is called leakage, leakage current of large LED, short life, low price.5, the use of different light emitting angle LED, its light angle is not the same. Special light angle, higher price. Such as full diffusion angle, higher prices.Key 6, life of different quality is life, life is decided by the light fades. A small decline, long service life, long service life, high price.
