We bathe in all kinds of lights in our daily lives. There are cold lights and warm lights. So which ones are cold lights and which ones are warm lights? The editor of Zhengzhou City Lighting will learn some of these knowledge with you!
The main difference between cold light and warm light is the color temperature. Warm light is more reddish, cold light is more blue.
Cold light: The color becomes blue when the color temperature exceeds 5000K, giving people a cool feeling. So it's called cold light.
Warm light: When the color temperature is below 3000K, the light color will appear reddish, giving people a warm feeling.
The original fluorescent lamp is cold light, and the incandescent lamp is warm light. Current energy-saving lamps and LED lamps are of the same variety, both cold light and warm light.
一、cold light
1. Brief introduction: cold light lamp is a cold light board using the main light source material in the 21st century. Cold light is a kind of low-power halogen tungsten lamp, between 25-50W, equipped with reflector to illuminate in a certain direction and emit white light. It is widely used in decorative lighting occasions as shop windows or store layouts, low-voltage power supply, and electronic transformer as light power supply .
2. Features: cold light lamp is an advanced flat film (uniform light emitting) cold light source, ultra-thin (thickness 0.2mm), small size, it can be produced in any size and pattern, flexible, flexible, Paste and hang, adjustable brightness, it is very energy-saving, and does not produce any heat when emitting light. It is convenient to carry, anti-breaking, can be curled, simple application, both AC and DC, environmental protection and energy saving, green products, the light is soft, not dazzling, and human The eyes will not cause harm.
