LED to choose skills

1, brightness LED brightness is different, the price is different. Used for LED lamps and lanterns, the LED should comply with the laser level Ⅰ class standard.
2 antistatic ability of leds, antistatic ability, long service life, thus higher prices. Antistatic usually greater than 700 v LED can be used in the LED lighting.
3, consistent LED wavelength wavelength, color is consistent, such as request the same color, the price is high. Not the manufacturer of the LED light color separation instrument is not easy to produce pure color products.
4, the leakage current of LED is a one-way conductive lights, if there is a reverse current, is called the leakage, leakage current big LED, short service life, low price.
5, light Angle USES different LED light Angle is different. Special light Angle, the price is higher. Such as the diffuse Angle, the price is higher.
6, different life quality is the key to life, life is decided by droop. Droop small, long service life, long life, high price.
7 LED lights for chip, chip, different chip, price difference is very big. Chip is more expensive, Japan, the United States generally chips in Taiwan and domestic price is lower than the day, the United States.
8 chip, chip size to the size of the side length, said big LED chip quality is better than that of the small chips. The price is proportional with the chip size.
9, colloid ordinary LED colloid generally for epoxy resin, leds with uv radiation and fire retardant added more expensive, high quality outdoor LED lighting should be uv and fire prevention.
