Abstract
The utility model discloses a long-life lamp. Because the long-life lamp does not have expensive components such as transistor, capacitor or inductor, etc., the utility model has the advantages of low cost, reliable and safe. The technique applies to various screw or bayonet illumination lamps, festoon lamps (comprises longevity glittering festoon lamp), infrared lamps and other lamps and lanterns which are started by filaments.
Description
This is a kind of than the long-life lamp of ordinary lamps long working life more than 5～10 times.
The employed various methods that lamp is lengthened the life in prior art, all be generally outside lamp, to use the bigger devices of expense such as halfwave rectifier diode, resistance and other electronic delay startup, (please referring to the 41st page of 1989 the 2nd phase " the electric world "), these install all ubiquity installation inconvenience, it is big self to consume energy, the shortcoming that cost is high.
According to bimetal leaf heated bending principle, at the lower two filaments of bimetal leaf 3 controls of the inner installation cost of lamp, as shown in the figure: when mains switch K connected, filament 1 and filament 2 were connected on the power supply, because series impedance is bigger, it is less to start impulse current, thereby the life-span of lamp is prolonged, after filament 1,2 is lighted, bimetal leaf heated bending and make filament 1 short circuit, after this to press rated power normally luminous for filament 2, because bimetal leaf keeps heating status, filament 1 long-term short circuit.Turning on light and repeat said process after lamp closes makes lamp normally luminous.
Claims (2)
1, a kind of long-life lamp is characterized in that being equipped with a bimetal leaf and composite wire.
2, bulb as claimed in claim 1, its domestic animal are that bimetal leaf is contained in the bulb and in parallel with filament 1.
