Abstract
The utility model discloses an energy-saving bulb with long service life, comprising a glass bulb (6), a filament (7), a screw (5) and an insulator (4). The utility model is characterized in that a semiwave rectifier circuit which comprises a crystal diode (1) and can meet the rated voltage and current is connected in series with the circuit of the bulb. The utility model has the advantages that the service life is longer than the ordinary incandescent lamps by 30 times; the energy can be saved.
Description
The utility model relates to a kind of bulb.
Civil power is 220 volts, 50HZ alternating current at present, and lighting 80% is an incandescent lamp.Existing incandescent lamp bulb is made up of glass envelope and filament, and screw socket and conduction weld tabs constitute two utmost points.The current density of moment by the tungsten filament influence of various factors such as big owing to turn on light, bulb causes damage easily, and the life-span is very short about 1000 hours, needs often to change, and brings economic loss to the user.
The purpose of this utility model provides a kind of Energy-saving bulb with long service life, and it can reduce economic loss of user.
The utility model is the improvement of existing incandescent lamp bulb, and glass envelope, filament, screw socket, insulator are arranged, and it is characterized in that in bulb circuit serial connection one can only satisfy the crystal diode half-wave rectifying circuit of rated voltage and electric current.
The utility model has increased withstand voltage, thereby has prolonged about 30 times of useful life, and can save the energy owing to crystal diode of polyphone in the circuit of filament has reduced the current density of passing through.
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Accompanying drawing 1 is the structural representation of an embodiment of the utility model.
Accompanying drawing 2 is its circuit diagram.
The utility model has glass envelope (6), filament (7), screw socket (5), insulator (4), one crystal diode (1) that can only satisfy rated voltage and electric current is housed on the bulb top center position, the conduction weld tabs that promptly replaces the ordinary incandescent lamp bubble with the latter, on insulator (4), put a galvanized washer (3) around crystal diode (1), one bronze medal cap (2) is arranged on the latter, it can adopt the battery copper cap No. 5, and the size of this packing ring (3) and copper cap (2) need make the international standard of the size conforms screw-socket bulb of crystal diode (1) both positive and negative polarity insulating space.Adopt senior adhesive that crystal diode, galvanized washer, copper cap are bonded on the bulb screw mouth top insulator.
Because string advances crystal diode, voltage on its filament is much smaller than 220V, approximately has only 140V, make the power of bulb descend about 30%, this is under current State Grid duty ratio situation more in short supply, the electrical network drawing-path electricity limiting is very frequent, uses the utility model can save electric power, to alleviate the contradiction of supply of electric power deficiency.
Claims (1)
1, a kind of Energy-saving bulb with long service life has glass envelope (6), filament (7), screw socket (5), insulator (4), it is characterized in that in bulb circuit polyphone one can only satisfy crystal diode (1) half-wave rectifying circuit of rated voltage and electric current.
