Generally speaking, the indoor basic lighting uses a flood light source, which only needs to reach a certain brightness and the human eye feels comfortable. The light source used can not produce glare that makes people visually uncomfortable (the contrast of light is too strong or too much reflected light), so the LED light source should be properly selected, and the LED downlight and tube with PC cover or sanding cover are the best choice. PC can also be selected. The led fluorescent lamp of the hood is directly illuminated, and the power (wattage) of the light source cannot be too large. Together with our habits, the LED light source with a color temperature below 6000K is selected. The special lighting in the key areas of the room is more professional, and the choice of LED light source is exquisite. At the time, the first use of the collection source - LED spotlights. For example, the display of clothing, gold jewelry, jewelry, platinum jewelry and other products, as well as dishes, industrial lighting, etc., need to carefully describe the light source. Pay attention to four points when purchasing: color temperature, color rendering index, light angle, power (illuminance and brightness) of LED light source. Taking gold jewelry as an example, the color temperature of the LED light source cannot be higher than 3200K (warm color), the flash index cannot be lower than 80, the beam angle should not be too large (too much to be floodlight), and the power should not be too small. However, if used for platinum jewelry, the color temperature of the LED light source should not be less than 6000K, and the color rendering index should not be lower than 75. Therefore, it can be seen that although it is also used for indoor lighting, but different lighting purposes, light sources and lamps The choice is very different, and the choice of light source must be cautious.
