The working principle of the electronic energy-saving lamp: using a high-frequency electronic ballast to invert the 50HZ mains to 20-50KHZ high-frequency voltage to ignite the fluorescent lamp. It has the following advantages:
(1) High luminous efficiency
Light efficiency, that is, luminous efficiency, refers to the ratio of the luminous flux emitted by a light source to the electrical power consumed. It can be expressed in 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 for measuring the brightness of the lamp, expressed in LM.) Compact fluorescent lamps are compared with ordinary bulbs. The luminous efficiency is increased by about 5-6 times. For example, the luminous flux of an 11W energy-saving lamp is equivalent to a 60W ordinary incandescent lamp.
(2) long life
The so-called life refers to the cumulative time of a finished lamp from ignition to "burnout" or lamp operation to any requirement below the life performance specified in the standard. Ordinary incandescent bulbs have a rated life of 1000 hours, and compact fluorescent lamps typically have a lifetime of 5,000 hours.
(3) good color rendering
A variety of similar light sources will show different light colors. We use the CRI (COLOR RENDERING INDEX) to determine the range from 0 to 100. The color of the incandescent lamp and the daytime energy index is 100. Displaying the level of the index directly reflects the color rendering of the light. The higher the color rendering index of the light, the more the true color of the object under its illumination is reflected. On the contrary, the color of the object will be distorted. In general, 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 compact fluorescent lamp uses a rare earth trichromatic phosphor, and its color rendering index is about 80RA, which is significantly improved compared with ordinary fluorescent lamps. If cheap halogen powder is used as the raw material, this effect will not be achieved.
(4) Small size, beautiful appearance and easy to use.
Due to the high power load of the compact fluorescent lamp, it is compact and beautiful, and has a good decorative effect. The lamp cap specification of the integrated energy-saving lamp is basically the same as that of the ordinary bulb, so it can be used directly instead of the ordinary bulb. Its market capacity is huge and it is easy to promote and apply. It can be said that the compact fluorescent lamp concentrates on the power saving of the fluorescent lamp, the long life and the incandescent lamp are small in size, the color is good, and the use is simple, and the like is a typical light source of modern indoor lighting, and has become a recommended product of the international green lighting source. There are huge potential markets and development prospects.
