led floodlights from a specific point to all directions evenly illuminate the object, use it to analog light bulbs and candles better, led floodlights can be placed anywhere in the scene. Generally produced in the main advertising company which can often see. Here, we mainly talk about how to buy led floodlights should pay attention to what the problem.
What is led flood light:
led flood light is a point of light can be uniformly illuminated in all directions, its range of illumination can be adjusted in the scene as a positive octahedral display.
How to buy led floodlights:
1, LED floodlight brightness (MCD) is different, the price is different. LED for LED lamps should meet the laser class Ⅰ standard.
2, anti-static ability Antistatic ability LED, long life, and thus high prices. Usually anti-static greater than 700V LED can be used for LED lighting.
3, the same wavelength of the LED, the same color, such as the required color, then the price is high. Producers who do not have LED spectrophotometers are difficult to produce pure color products.
4, leakage current LED floodlight is a one-way conductive light, if there is reverse current, then known as leakage, leakage current LED, short life, low prices.
5, the use of different angles LED light angle is not the same. Special light angle, the price is higher. Such as full diffuse angle, the price is higher.
6, the quality of life is the key to the quality of life, life by the decay of light. Light fades small, long life, long life, high prices.
7, the chip LED flood light for the wafer, different chips, the price difference is very large. Japan, the United States of the chip more expensive, generally Taiwan and domestic chip prices lower than Japan, the United States (CREE).
8, the chip size of the chip size to side length, large chip LED quality is better than the small chip. The price is proportional to the size of the chip.
9, colloidal colloidal LED colloid is generally epoxy resin, plus anti-ultraviolet and fire retardant LED more expensive, high-quality outdoor LED lighting should be anti-ultraviolet and fire.
