LEDFive parameters commonly used in line lights
When customers purchase LED line light products, it is necessary to understand some common parameters, such as brightness, wavelength, color temperature, etc. as a good or bad specification. Here are the common parameters of LED line light products, telling you how to choose LED line light products.
1. The brightness of the LED lamp includes: brightness L: the luminous flux of the illuminant in a unit area of a solid angle unit in a specific direction. Unit: Nitta (cd/m2). Luminous flux φ: the sum of the amount of light declared by the illuminator per second. Unit: Lumen (Lm), indicating how much the illuminant emits light, and the more the illuminance, the larger the lumen number. Then: the larger the lumen number, the more the luminous flux, the higher the brightness of the lamp.
2, the wavelength of the common LED, the color is common. It is difficult for producers without LED spectrophotometers to produce pure color products.
3. Color temperature is the unit of measurement for the color of the light, indicated by the value of K. The yellow light is "below 3300k", the white light is "5300k or more", and the intermediate color is "3300k-5300k". The customer can select the light source with the appropriate color temperature according to personal preference, the use environment and the lighting effect and atmosphere to be created.
4. Leakage current LED is a unidirectional conductive illuminator. If there is reverse current, it is called leakage, and LED with large leakage current has short life.
5, anti-static ability of the LED, long life, so the price is high.
