Abstract
The utility model relates to an incandescent lamp bulb which is composed of glass bulb, lamp filaments, a support bracket, leading wires, a lamp cap and a current limiting device. The current limiting device is composed of a bimetallic thermo-electric device and a current limiting resistor. The two lamp filaments are connected in parallel with the leading wires of the lamp filaments. The current limiting resistor is connected in series with the middle part of the leading wire of the lamp filament which is communicated with the fire wire of a power. A bimetallic thermal relay circuit is respectively connected with both ends of the current limiting resistor to form contact points. When the incandescent lamp bulb does not work, the contact points are disconnected; at the moment that the incandescent lamp bulb is communicated with electricity, the current passes through the current limiting resistor and the lamp filaments to form a return circuit. Thus, the surge current is reduced and the service life of the lamp filaments can be prolonged. After the incandescent lamp bulb is turned on, the contact points are connected, the current limiting resistor is not connected in the circuit, and then the incandescent lamp bulb normally works. If one lamp filament is burnt out, the other lamp filament can still maintain the illumination.
Description
The utility model relates to a kind of incandescent lamp bulb, present incandescent lamp bulb used in everyday has only a filament, because the cold-state resistance of tungsten filament is little, very big at moment, the impulse current of energized, and the 12-16 that can reach rated operational current doubly, often the disintegration of filament influences illumination.
The purpose of this utility model provides a kind of incandescent bubble, can reduce the energized impulse current of moment, avoids the disintegration of filament, the deficiency of influence illumination.
This incandescent lamp bulb is made up of glass bulb, filament, support, lead-in wire, lamp holder and current-limiting apparatus, 2 filaments are attempted by on the lead-in wire, current-limiting apparatus is made up of bimetal thermal relay and current-limiting resistance, current-limiting resistance is serially connected in the middle part of the heater lead of energize live wire, bimetal thermal relay is received the current-limiting resistance two ends respectively and is formed the contact, and the power of each filament is 1/2nd of bulb power.When bulb is not worked, the contact of bimetal thermal relay disconnects, when energized moment, power supply constitute loops through current-limiting resistance and 2 filaments, after bulb is lighted, because thermal effect effect, the closing of contact of bimetal thermal relay, current-limiting resistance is entered normal operating conditions by bypass, bulb.
This utility model incandescent lamp bulb compared with the prior art, because bulb is added with current-limiting apparatus, can reduce the energising impulse current of moment, prolong useful life of filament.And there are 2 filaments to work simultaneously in the bulb, wherein behind 1 filament blow, 1 filament still can be kept illumination in addition, can not cause unexpected dark.
Figure is a kind of structure chart of incandescent:
(1) lamp holder, (2) support, (3) current-limiting resistance, (4) bimetal thermal relay, (5) lead-in wire, (6) glass bulb, (7) filament.
Provide specific embodiment below in conjunction with accompanying drawing:
This incandescent lamp bulb is made up of glass bulb, filament, support, lead-in wire, lamp holder and current-limiting apparatus, glass bulb (6), support (2) are identical with the prior art manufacturing process with lamp holder (1), current-limiting apparatus is made up of bimetal thermal relay (4) and current-limiting resistance (3), current-limiting resistance (3) is concatenated into the middle part of the heater lead (5) of energize live wire, and its resistance is 10 times of filament cold-state resistance value.Bimetal thermal relay (4) is received the two ends of current-limiting resistance (3) respectively and is formed the contact, and 2 filaments (7) are attempted by on the heater lead (5), and the power of each filament is 1/2nd of bulb power.The contact of bimetal thermal relay when bulb is not worked (4) disconnects, energized moment, electric current is through current-limiting resistance (3), filament (7), lead-in wire (5), formation loop, after bulb is lighted, the closing of contact of bimetal thermal relay (4), current-limiting resistance (3) be by bypass, the bulb operate as normal, after the outage, disconnect after the contacts cool down of bimetal leaf thermorelay (4).
Claims (1)
1, a kind of novel incandescent lamp bulb is by glass bulb, filament, support, lead-in wire, lamp holder and current-limiting apparatus are formed, it is characterized in that: 2 filaments are attempted by on the heater lead, current-limiting resistance is serially connected in the middle part of the heater lead of energize live wire, and bimetal thermal relay is received the current-limiting resistance two ends.
