Low-voltage mercury-free energy-saving bulb

Abstract

The invention discloses a low-voltage mercury-free energy-saving bulb, which overcomes the defects of short service life, high production cost, electronic element resource waste and mercury pollution existing in the conventional energy-saving lamp. In the bulb, two electrodes are arranged in a lamp housing; electronic powder is coated in the electrodes; electric energy is converted into light energy on the basis of the electrodes in the lamp housing; after being connected with a 220V mains supply through a metal wire, the bulb receives current to activate the electronic powder on the electrodes to ionize; and fluorescent powder in the lamp housing is activated under the auxiliary action of neon, so that the electric energy is converted into the light energy. Since the neon emits red light, the fluorescent powder is required to be prepared to be blue, and approximate white light is realized by a color reduction principle. Through the bulb, a process of boosting voltage to heat a filament by using an electronic circuit in the conventional energy-saving lamp is avoided, so that the production cost of the low-voltage mercury-free energy-saving bulb is greatly reduced, the effective life for work and use is prolonged, the amplitude of working voltage is widened, the problem of mercury pollution of the normal energy-saving lamp is solved, the requirement of the normal civil lighting can be met, and the waste of energy, particularly electronic elements, is effectively avoided.

Description

technical field [0001] The utility model relates to a high-efficiency conversion technology of electric energy to light energy for a new type of low-pressure mercury-free energy-saving bulb, which belongs to the electric light source industry of glass processing, especially the high-efficiency electric energy to light energy conversion mode and the advantages of low cost and long life. Background technique [0002] At present, the working voltage of ordinary energy-saving lamps is about 400-600 volts. To realize the operation of energy-saving lamps, the voltage must be boosted under the action of electronic circuits, which increases the production cost of energy-saving lamps on the electronic circuits. Moreover, the filament of ordinary energy-saving lamps has a short service life, and the working principle of ordinary energy-saving lamps is not suitable for the energy-saving concept of "turning off the lights when people leave". The high cost of energy-saving lamps will ine...
