White light is generally at 4000K color temperature, which is cold, while warm white light is at 3000K color temperature, which is yellow. It is generally good to use positive white light in the living room. Warm white light is more suitable for living room. Warm white is close to the color temperature of the bulb, and the color temperature of the white fluorescent lamp is above it.
LED lighting is generally divided into cold white light and warm white light. The color temperature of cold white light is 4000 K-8000 K, and the higher the color temperature. The whiter the light color is, the ordinary fluorescent lamp is cold white with a color temperature of about 5500K, and the color temperature of warm white is 2500 K-4500 K The lower the color temperature, the yellower the light color is. For example, household incandescent bulbs are warm white light with a color temperature of about 3000 K. Under the irradiation of high color temperature light sources, if the brightness is not high, it will give people a cold atmosphere. Under the irradiation of low color temperature light source, if the brightness is too high, it will give people a sultry feeling.
Matters needing attention in lighting use
When in use, the rated voltage of the bulb should be consistent with the power supply voltage. In order to make the light emitted by the bulb distribute evenly and avoid glare, it is best to install a moderate lampshade according to the requirements of the degree.
When installing high-power incandescent bulbs, good ventilation should be considered to avoid overheating of bulbs and loosening of glass shells and lamp sockets.
When the light bulb is used in the open air, there should be rain-proof facilities to prevent the light bulb from being damaged by rain. For indoor light bulbs, the dust and dirt on the bulbs and their surfaces should be cleaned frequently to keep them clean and bright.
