Fluorescent lamp coal has some shortcomings: the light source flickers the eye, the switch lamp takes time, the color rendering is poor, and the pan-green light is excessive. However, compact fluorescent lamps have improved these problems, and different color rendering properties and illumination colors have been developed to meet the requirements of the light environment.
When the color temperature is below 3000K, the light color begins to be somewhat reddish, giving a warm feeling; when the color temperature exceeds 5000K, the color begins to lean toward blue light, giving a cold feeling. It can be seen from Table 1 that the current fluorescent lamp can not only be 6 times more efficient than incandescent lamps, but also shows its good energy-saving performance, and has a large selection range of display color and color temperature. In places such as parking lots and warehouses where color rendering is not demanding, fluorescent lamps with a color rendering of about 60 can be selected; fluorescent lamps with a color rendering of about 85 can be used in general residences, general working environments, general shopping malls, etc.; For places with high color rendering requirements, such as department stores, hospitals, art galleries, etc., fluorescent lamps with a color rendering of about 95 are required; for warm lighting environments, fluorescent lamps with a color temperature of about 3000K can be selected; they need to be perfectly combined with natural light. For the place, you can choose a white series fluorescent lamp with a color temperature of 3500~4000K; for a place that needs to be similar to natural light but emphasizes the cool color effect, you can choose a fluorescent series fluorescent lamp with a color temperature of 5000~6500K. It is not difficult to see that with the technological advancement of fluorescent color broad color rendering and multi-color temperature, it has replaced incandescent lamps in some areas of indoor lighting, and it will replace incandescent lamps in a wider range of fields, including home lighting. .
The compact fluorescent lamp is small in size, high in luminous efficiency, energy-saving and energy-saving, and can be installed in a conventional lamp holder for easy replacement. Therefore, compact fluorescent lamps can completely replace incandescent lamps.
In the lighting field of shopping malls, hotels, hotels, homes, etc., in addition to ordinary indoor lighting, in the local lighting that needs key and decorative lighting places, tungsten halogen lighting can be used. The life of tungsten halogen lamps is longer than that of ordinary incandescent lamps. The ordinary incandescent lamp is high, which can meet the requirements of high color rendering and warm color.
