400w Led Flood Light Manufacturer Shares Knowledge About Led Lighting Parameters
It is necessary to understand some of the basics of LED lighting, as this will not be biased when selecting LED lighting. Then the following 400w Led Flood light manufacturers will list some common LED lighting parameters.
1. Luminous flux: Symbol Φ, unit Lumens Lm, Description The sum of the amount of light emitted by the illuminator per second, ie the luminous flux.
2. Light intensity: symbol I, unit Candela cd, indicating the luminous flux emitted by the illuminant in a solid angle in a specific direction unit.
3. Illuminance: Symbol E, unit Lux Lm/m2, indicating the luminous flux of the illuminant on the unit area of the illuminated object.
4. Brightness: Symbol L, unit Nibble cd/m2, indicating the luminous flux of the illuminant in a unit of solid angle unit area in a specific direction.
5. Light efficiency: unit lumens per watt Lm/w, indicating the ability of an electric light source to convert electrical energy into light, expressed as the luminous flux emitted divided by the power consumption.
Average life: Units per hour, which refers to the number of hours when a batch of bulbs is damaged to 50%.
6. Economic life: unit hours, the combined beam output is reduced to a specific number of hours while considering the damage of the bulb and the attenuation of the beam output. This ratio is 70% for outdoor light sources and 80% for indoor light sources such as fluorescent lamps.
7. Color temperature: When the color of the light emitted by the light source is the same as the color of the black body at a certain temperature, the temperature of the black body is called the color temperature of the light source.
The color temperature of the light source is different and the light color is different.
a. Color temperature and brightness Under the illumination of high color temperature light source, if the brightness is not high, it will give people a kind of yin atmosphere; under low color temperature light source, the brightness will be too high, which will give people a feeling of sultry heat.
b. Comparison of light color In the same space, two kinds of light sources with large color difference are used, and the contrast will have a layer effect. When the light color contrast is large, the level of light color can be obtained while obtaining the brightness level.
c. Color rendering: The color rendering of the light source is indicated by the color rendering index, which indicates that the color deviation of the object under the light from the reference light (sunlight) can reflect the color characteristics of the light source more comprehensively.
d. Two kinds of color development: faithful color development, can correctly represent the original color of the material, use a light source with a high color rendering index (Ra), the value is close to 100, the color rendering is good; the effect is color, and the specific color should be clearly emphasized. Color, beauty of life can use the additive color method to enhance the color effect. Irradiation with a low color temperature light source can make the red more vivid; using a medium color temperature light source to make the blue have a cool feeling; using a high color temperature light source to make the object have a cold feeling.
