Energy-saving lighting with high efficiency. Luminous efficiency, or luminous efficiency, refers to the ratio of the luminous flux emitted by a light source to the electric power consumed. It can be expressed by the number of lumens per watt or LM/W (luminous flux: refers to the amount of light emitted by the light source per unit time, which is an important indicator to measure the brightness of the lamp, expressed by LM). Compared with ordinary bulbs, the luminous efficiency of energy-saving lamps is about 5-6 times higher. For example, the luminous flux of 11W energy-saving lamps is equivalent to 60W ordinary incandescent lamps.

Energy-saving lamps have a long life. The so-called life span refers to the cumulative time of a finished lamp from ignited to burned out or the lamp works to be lower than any requirement of the life performance specified in the standard. The rated life of ordinary incandescent bulbs is 1,000 hours, and the life of energy-saving lamps is generally 5,000 hours.

Energy-saving lamps show good color. A variety of different light sources will show different light colors. We use the color rendering index CRI to determine the range from 0 to 100. The color display index of incandescent lamps and daytime sunlight is 100. The level of the display index directly reflects the color rendering of light. The higher the color rendering index of light, the more true the color of the object under its illumination can be reflected. On the contrary, the color of the object will be distorted. Generally speaking, as long as the color rendering index of light is greater than 75, the color of the object can be truly reflected without distortion. The color rendering index of the rare earth trichromatic phosphor energy-saving lamp is about 80RA, which is significantly higher than that of ordinary fluorescent lamps. If cheap halogen powder is used as raw material, this effect will not be achieved.

Energy-saving lamps are compact and easy to use. Because the energy-saving lamp has a higher power load, its volume is small and beautiful, and it also has a better decorative effect. The lamp cap specifications of the integrated energy-saving lamp are basically the same as ordinary bulbs, so it can be used directly instead of ordinary bulbs. It has a huge market capacity and is easy to promote and apply. It can be said that the energy-saving lamp has the advantages of fluorescent lamp energy saving, long life, small size, good color rendering, and easy use of incandescent lamps. It is worthy of being a typical light source for modern indoor lighting, and it has become a recommended product for international green lighting sources. It has huge potential Market and development prospects.
