Abstract
The utility model discloses a fluorescent lamp capable of working after a filament in open circuit or short circuit. The fluorescent lamp comprises a fluorescent tube and an electronic ballast; two filaments are respectively arranged at two ends in the fluorescent tube; the electronic ballast is connected between the two filaments; the other ends of the two filaments are connected through a capacitor; and a protection circuit is connected in parallel with two ends of each filament and is composed of a plurality of fast recovery diodes which are connected in parallel, wherein at least one fast recovery diode is connected into the circuit in the direction opposite to that of the other fast recovery diodes. The fluorescent lamp has the advantage that the service lives of both the fluorescent tube and a switch can be prolonged.
Description
[technical field]
The utility model relates to self-ballasted fluorescent lamp, belongs to the electrical lighting technical field, specifically is a kind of fluorescent lamp that can continue to use after tube filament fusing or short circuit.
[background technology]
Fluorescent lamp is a kind of energy-conservation, efficient, controllable green light source of colour temperature.Along with the continuous development of society and science and technology, fluorescent lamp is the status of replace incandescent progressively, has saved about 80% the energy for the mankind.Various countries formulate and the policy of having put into effect relevant fluorescent lamp replacement incandescent lamp one after another for realizing the sustainable development of energy-conserving and environment-protective.But because a variety of causes, fluorescent lamp can cause open filament or short circuit after using a period of time, and power saving fluorescent lamp just can not continue to use like this.Can make an end reactivation of filament that breaks although use the fluorescent tube short-circuit method, not popularize and product own characteristic restriction (as the integrated encapsulation of compact electronic fluorescent lamp) because of technical key point, numerous users do not have ability to implement, thereby cause the wasting of resources.
[utility model content]
The utility model has overcome the phenomenon that existing tube filament open circuit damages, the shortcoming that causes large quantities of fluorescent tubes and integrated light fixture to scrap, constitute the technical scheme that fluorescent lamp is continued to use in the loop by peripheral circuit after being intended to provide a kind of tube filament fracture of wire or short circuit, prolong the useful life and the switch life of fluorescent tube.
For achieving the above object, the utility model has adopted following technical proposal:
The fluorescent lamp that a kind of open filament or short circuit still can be worked; include fluorescent tube YZ and electric ballast; two ends respectively are provided with a filament in fluorescent tube YZ; described electric ballast is connected between two filaments; two filament other ends connect by electric capacity; the two ends of each filament are parallel with protective circuit; this protective circuit is made up of a plurality of parallel connections fast recovery diode together, and wherein at least one fast recovery diode is opposite with direction in all the other fast recovery diode places in circuit.
The beneficial effects of the utility model are: 1, any one group of filament in two of fluorescent tube groups of filaments takes place one and opens circuit, and perhaps two groups of filaments all open circuit, and fluorescent tube can work on; Any one group is short-circuited in two groups of filaments of fluorescent tube, and perhaps two groups of filaments all are short-circuited, and fluorescent tube can work on; One group of filament is short-circuited in two groups of filaments of fluorescent tube, opens circuit with one group of filament, and fluorescent tube can work on.2, the utility model fluorescent lamp has effectively prolonged the useful life of product, through experimental verification, the fluorescent lifetime that this structure is housed has increased 20%-40% again on existing fluorescent lamp 8000-10000 hour basis, switch life improves 20%-40% on the basis of existing fluorescent lamp 5000-6000 time, avoided because of a large amount of wasting of resources and the environmental pollution that causes, raising fluorescent lamp product utilization rates of producing.

[embodiment]
The fluorescent lamp that a kind of open filament or short circuit still can be worked; include fluorescent tube YZ and electric ballast; two ends respectively are provided with a filament in fluorescent tube YZ; described electric ballast is connected between two filaments; two filament other ends connect; the two ends of each filament are parallel with protective circuit, and this protective circuit is made up of a plurality of parallel connections fast recovery diode together, and wherein at least one fast recovery diode is opposite with direction in all the other fast recovery diode places in circuit.
The quantity of described fast recovery diode is 2, and their directions are connected in parallel on the two ends of filament on the contrary.Between two groups of filament other ends, be connected with electric capacity.Any one group of filament in two groups of filaments of fluorescent tube takes place one and opens circuit, and perhaps two groups of filaments all open circuit, and fluorescent tube can work on; Any one group is short-circuited in two groups of filaments of fluorescent tube, and perhaps two groups of filaments all are short-circuited, and fluorescent tube can work on; One group of filament is short-circuited in two groups of filaments of fluorescent tube, and another group filament opens circuit, and fluorescent tube can work on.
Claims (3)
