Electromagnetic induction lamps have no electrodes and rely on the basic principles of electromagnetic induction and gas discharge to emit light. The absence of filaments and electrodes allows bulbs to last up to 100,000 hours, 100 times longer than incandescent lamps, 5 to 15 times longer than high pressure gas discharge lamps, and 5 to 10 times longer than compact fluorescent lamps.
Based on the above principles, the gas is discharged through a magnetic field to generate visible light. That is, the frequency generated by the electronic ballast is 230KHz, and the electromagnetic transformer composed of the metal coil magnetic ring creates a magnetic field around the glass tube (containing special working gas).
The discharge path caused by the coil forms a closed circuit, which causes the acceleration of the free electrons. These free electrons collide with mercury atoms to excite electrons. As the excited electrons retreat from a high-energy state to a low-energy state, they emit ultraviolet light, which is converted into visible light when passing through the trichromatic phosphor on the surface of the glass tube.
The electromagnetic induction lamp is a new invention of electric light source technology in the lighting industry. The advantages of the electromagnetic induction lamp are obvious. Compared with the traditional light source, the electromagnetic induction lamp has a long service life of 100,000 hours and is free of maintenance costs. High-quality light source with a color rendering index higher than 80 and a wide color temperature from 2700K to 6500K. The high color rendering makes the color of the object itself bright and realistic, and the high light efficiency of 80lm/W (150plm/W pupil lumens) makes the lighting more energy-efficient. The electromagnetic induction lamp also has more reliable instant start performance, low heat output, and more reliable ability to resist violent voltage fluctuations. Within the range of plus or minus 20V of the nominal operating voltage value, the ballast can work normally, and the luminous flux output The power consumption and lighting effects are only about 2% affected by the fluctuation voltage (including technical indicators such as color temperature and color rendering).
At the same time, the warm white light of the electromagnetic induction lamp is more suitable for road lighting than the yellow sodium lamp. Because the warm white light is close to the performance effect of sunlight, it can give passersby a warm feeling, and at the same time, it has better visibility. Identify the characteristics of the road and surrounding environment colors under warm white light to ensure the safety and comfort of road driving.
Compared with yellow light, the core advantage of warm white light is that it is more efficient in lighting and consumes less power. The same street light uses at least 10% less electricity than yellow light and reduces carbon dioxide emissions by 40%. Therefore, it also meets the requirements of environmentally friendly lighting and green lighting. Now that the energy crisis and the greenhouse effect are becoming more and more serious, it has a huge potential for popularization. The advanced concept of warm white light has been widely used in the United States, Britain, Belgium, Norway and other countries.
