Tricolor energy-saving lamp Tricolor energy-saving lamp (full name tricolor energy-saving fluorescent lamp) is a preheating cathode gas discharge lamp, which is divided into straight tube, single U-shape, double U-shape, 2D-shape and H-shape. Take the H-type energy-saving fluorescent lamp as an example. It consists of two glass tubes (the inner wall of which is coated with rare earth tricolor phosphor), a triple helix filament (cathode) and a lamp holder. Its working principle is similar to that of ordinary fluorescent lamps, that is, it can distribute inductive ballast (with frequency converter) or electronic ballast (without frequency converter).

Warm color lamp

The color temperature of warm light is below 3300K, which is similar to incandescent lamp. It has more red components and can give people a warm, healthy and comfortable feeling. Suitable for families, houses, dormitories, hotels and other places or places with low temperature.

Cold white light

Also known as neutral color, its color temperature is between 3300 K and 5300 K. Because of the soft light, neutral color makes people feel happy, comfortable and serene. Suitable for shops, hospitals, offices, restaurants, restaurants, waiting rooms and other places.

cold light

Also known as daylight color, its color temperature is above 5300K, and the light source is close to natural light, which makes people concentrate. Suitable for offices, conference rooms, classrooms, studios, design rooms, library reading rooms, exhibition windows and other places.

It is difficult to give consideration to both color rendering performance and lamp efficiency. In Japan, the first fluorescent lamp to realize this is a tricolor fluorescent lamp with a color temperature of 5000K K K.

The tricolor fluorescent lamp improves the efficiency of the lamp through green light, increases blue light and red light, and properly balances the three colors, thus successfully obtaining a new fluorescent lamp with high light efficiency and high color rendering performance.

By further changing the mixing ratio of these three lights, a tricolor fluorescent lamp (2700 ~ 3000 K) with warm light effect similar to a light bulb was born. Trichromatic fluorescent lamps with neutral white light in spring (4000 ~ 5000 K); There are fresh and bright daylight tricolor fluorescent lamps (6200~6700K).
