High-efficiency energy-saving bulb

Abstract

The invention discloses a high-efficiency energy-saving bulb. The device comprises an E27 joint, an upper plastic shell, a switch power supply plate, a nano reflecting hood, a U-shaped and spiral energy-saving lighting tube, a lower plastic shell for fixing the U-shaped and spiral energy-saving lighting tube and a glass ball hook with an outer photocatalyst, wherein the nano reflecting hood is assembled on the plastic shell in a slipknot mode. The device mainly improves the product luminance on the working surface and the illuminated surface on the basis of the same power consumption and realizes high efficiency.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to a high-efficiency and energy-saving bulb. Background technique [0002] Ordinary incandescent light effect is about 10 lumens per watt, and its lifespan is about 1000 hours. Its working principle is: when the lamp is connected to the circuit, the current flows through the filament, and the heating effect of the current makes the incandescent lamp emit continuous visible light and Infrared rays, due to the high temperature of the filament during work, most of the energy is wasted in the form of infrared radiation. Due to the high temperature of the filament, the evaporation is also very fast, so the life is greatly shortened, about 1000 hours. [0003] The energy-saving lamp mainly heats the filament of the lamp tube through the ballast. When the temperature is about 1160K, the filament starts to emit electrons (because some electronic powder is coated on the filament), and the electrons coll...

Problems solved by technology

[0003] The energy-saving lamp mainly heats the filament of the lamp tube through the ballast. When the temperature is about 1160K, the filament starts to emit electrons (because some electronic powder is coated on the filament), and the electrons collide with the argon atoms to produce inelastic collisions. After the argon atoms collide After gaining energy, it hits mercury atoms. After absorbing the energy, the mercury atoms transition to generate ionization and emit 253.7nm ultraviolet rays. The ultraviolet rays excite the phosphor to emit light. Since the temperature of the filament is about 1160K when the fluorescent lamp is working, it is 2200K-2700K higher than the working temperature of the incandescent lamp. It is much lower, so its life is greatly improved, reaching more than 5,000 hours. Because it does not have the current heating effect like incandescent lamps, the energy conversion efficiency of phosphors is also very high, reaching more than 50 lumens per watt, and the brightness is the same as that of incandescent lamps with the same power. It is more than 5 times that of the lamp, especially the brightness made of high-efficiency phosphor is even higher. It is a common lighting fixture widely used by human beings. It is widely used in supermarkets, docks, schools, factories, offices and household lighting. The consumption is large, but Because the light bulb is a fluorescent tube, it emits light at multiple points, so the light effect is multi-point, and people will feel dizzy and uncomfortable when looking at it!

[0004] Today's society advocates energy conservation and environmental protection, replacing 40W incandescent bulbs with 15W / 18W high-power energy-saving bulbs, the energy-saving effect is not obvious

[0005] Air pollution is serious in daily life, and a large number of harmful bacteria exist in the air, which is not good for human health
