1. Light efficiency: The efficiency of the light source will be converted into visible light, that is, the light consumption of the luminous flux emitted per watt of power. The higher the value of the standard light source efficiency, the light efficiency is an important parameter to evaluate the performance.
2. Luminous flux: the sum of the amount of light emitted by the luminous body, that is, the luminous flux of the light source. The more light, the greater the number of lumens.
3. Light intensity: In a specific direction or angle of light radiation energy, light intensity can express the characteristics of light sources, lamps or reflectors.
4. Illuminance: The luminous flux received per unit area, in the lighting design, different occasions have different illumination standards.
5. Brightness: also known as brightness, the luminous intensity of a luminous body or a unit area of photons emitted (or emitted).
6. When the absolute temperature is reached, the standard black body will be heated, and the temperature will rise to a certain temperature, and the color will gradually change from red/light red/orange/white/blue-white/blue. The light color change characteristics of the light source using this light color are the same as that of the black body under the same color light. At a certain temperature, we call the black body of absolute temperature as the light source of correlated color temperature, low color temperature light color is warmer, high color temperature light color is colder.
