Abstract
The utility model relates to an energy-saving durable lamp bulb provided with a thermoswitch composed of a thermistor and a temperature sensitive sheet metal, and the thermoswitch is connected in series in the filament loop. The resistance of the thermistor substitutes the thermal resistor of the bulb when the circuit is communicated momentarily. Thereupon the heating of the filament makes the sheet metal deform, the thermistor short-circuit and the filament conduct. The thermal resistor in the filament loop equals the resistance of the thermistor at initial time to eliminate the effect of 'overcurrent '. The utility model has the advantages of few electric energy consumption, easy fabrication, simple structure and long service life.
Description
The utility model proposes a kind of lighting bulb of durable energy saving.
The bulb of general lighting is made up of lamp holder, lead-in wire, evacuated glass foam and filament, and its filament cold resistance is little 10～20 times than thermal resistance, and the moment of turning on light produces very strong " overcurrent ", and power consumption and generation forceful electric power magnetic impact, and make bulb be easy to damage.
The purpose of this utility model is that proposition is a kind of simple in structure, can eliminate the energy-conservation long-lived again bulb that " overcurrent " impacts.
The Energy-saving durable lamp bulb that the utility model proposes is the thermoswitch that series connection one is made up of the thermistor and the thermometal sheet of tool negative temperature coefficient in the filament loop of bulb.When the moment of bulb energized, resistance is bigger at normal temperatures owing to thermistor, so electric current is less, the filament temperature of bulb raises thereupon, thermometal sheet generation deformation, make the thermistor short circuit, the direct conducting of filament, the thermal resistance basically identical of thermistor normal temperature resistance and bulb, so the moment of turning on light and the resistance basically identical of bulb adstante febre, therefore electric current is stable, has eliminated " overcurrent " electromagnetic impact to filament, has reached energy-conservation and long-lived purpose.
Below in conjunction with description of drawings: Fig. 1 is the schematic diagram of Energy-saving durable lamp bulb, and Fig. 2 is the thermoswitch schematic diagram.
The thermoswitch of the Energy-saving durable lamp bulb that the utility model proposes (2), can be contained in the glass core pipe of bulb by lead-in (3), thermistor (4), thermometal sheet (5) and lead-out wire (6) constitute, bulb is connected circuit moment, electric current is earlier by thermistor (4), because resistance height under thermistor (4) normal temperature, electric current is less, not having " overcurrent " produces, electric current is by filament (1), and temperature increases, thermometal sheet (5) heated bending, electric current is promptly by thermometal sheet (5), make thermistor (4) short circuit, the electric current that passes through on the filament is stable always, does not have the power consumption of " overcurrent ", make bulb energy-conservation, and long service life is compared energy-conservationly about 5% with common bulb, bulb life can prolong 4～8 times.
The Energy-saving durable lamp bulb that the utility model proposes, simple in structure, durable energy saving, easily manufactured, be convenient to promote the use of.
