Energy saving lamp bulb

Abstract

The invention discloses an energy saving lamp bulb. The energy saving lamp bulb comprises a bulb adaptor, a housing, an energy saving lamp tube and a light reflection cover, wherein the bulb adaptor is connected with the housing, the housing is connected with the light reflection cover, and the energy saving lamp tube is electrically connected with the bulb adaptor and placed in the light reflection cover. The energy saving lamp bulb further comprises a light transmitting cover and a light reflection film, wherein the light reflection cover is connected with the light transmitting cover in matching mode, the interior of the light reflection cover is plated with the light reflection film, and the surface of the light reflection cover is provided with a heat dissipation portion and a light reflection arc portion. The energy saving lamp bulb has the advantages that dust is prevented from entering into the energy saving lamp bulb and accordingly dust prevention effects are achieved by relatively sealing the energy saving lamp bulb, brightness of light emitted from the energy saving lamp tube is sufficiently enhanced and accordingly electricity is saved well by performing cohesion on the light for three times through the light transmitting cover, the light reflection film and the light reflection arc portion, and simultaneously the energy saving lamp tube is prevented from overheating and accordingly service life of the energy saving lamp tube is prolonged by dissipating heat for the energy saving lamp tube through the heat dissipation portion.

Description

technical field [0001] The invention relates to the field of lighting fixtures, in particular to an energy-saving light bulb. Background technique [0002] 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 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 15,000 hours. Because it does not have the curre...

[0002] 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 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 15,000 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, but there are still some deficiencies in the prior art. The energy-saving lamps with low power often fail to achieve the ideal lighting effect. In order to achieve the ideal lighting effect, the power saving efficiency will be discounted. Often a satisfactory result cannot be obtained

Bulbs are the most important components of energy-saving lamps, but after a certain period of use, the bulbs will emit a lot of heat. If the heat is not discharged, the components of the bulb will be worn out; at the same time, it is inevitable to attract dust due to static electricity. If dust is deposited on the lamp tube, it will affect the lighting brightness of the bulb, and even prone to electric leakage accidents, which will affect its life
