Abstract
The utility model relates to an energy-saving lamp with a filament difficult to burn out, which is characterized in that two connectors of the filament extend out of a lamp tube, one connector is connected with a circuit in parallel through a capacitor and a choke coil, and the other connector is idle; or the two connectors of the filament are combined into a terminal which is then connected with the circuit by the capacitor and the choke coil. As the filament and the circuit can not form the circuit, no current flows, and the filament can not be burned out, so that the service life of the energy-saving lamp is greatly prolonged.
Description
Technical field
The utility model belongs to lighting apparatus, particularly relates to a kind of electricity-saving lamp that is difficult for the disintegration of filament.
Background technology
At present, the electricity-saving lamp that people use, common have single U, double-H groove weld, three U and a spirality, filament in these power saving fluorescent lampss, coiled in fluorescent tube, two terminations that extract in the fluorescent tube, all be by lead, be connected on the circuit, make filament and the circuit that is connected form a loop.When starting, the filament in the fluorescent tube just has electric current to pass through.Often start, filament is heated repeatedly, very easily quickens the aging of filament, until being broken by scorification, has so also just shortened the useful life of electricity-saving lamp.In the reality, the damage of electricity-saving lamp mostly terminates because of filament blow.
Summary of the invention
The purpose of this utility model, will provide does not exactly have electric current not form the loop, be difficult for the electricity-saving lamp of the disintegration of filament by, filament and circuit on a kind of filament.The technical scheme that the utility model adopted is: filament extends out in fluorescent tube, is connected with two seal wires respectively, and in two seal wires that each filament connected, wherein a seal wire is connected with circuit with choke by electric capacity, and another seal wire is idle; Two seal wires that perhaps will be connected with filament are merged into terminals, link to each other with circuit with choke by electric capacity again.Like this, just form between the seal wire that is connected with filament in the fluorescent tube, connect an electric capacity, this electric capacity one end links to each other with another electric capacity, and the other end links to each other with choke, is connected on the circuit again.When starting, electric current is just by choke and electric capacity, and the seal wire that is connected with filament does not have electric current and passes through, at supply voltage is under the situation of 170V-250V, and on the electric capacity that connects between two filaments, voltage can reach more than the 400V, make between two filaments and form electrion, thereby light fluorescent tube.The utility model perhaps is merged into terminals and connects owing to adopt the single-ended connection of filament, does not form the loop with circuit, so just there is not electric current to pass through, filament can not be blown, and has prolonged the useful life of electricity-saving lamp greatly yet.

Embodiment
As shown in Figure 1, filament 2a, 2b extend out in fluorescent tube 1, are connected with two seal wires respectively, in two seal wires that each filament connected, one is connected with circuit, and another root is idle, electric capacity 4 plays increases the voltage effect, and between two filament 2a, 2b, the one end links to each other with electric capacity 3, electric capacity 3 works the direct current effect that intercepts, the other end links to each other with choke 5,5 metering functions of choke, and electric capacity 3, electric capacity 4 and choke 5 are cascaded, filament is in parallel with electric capacity 4, is connected on the circuit again.
Among Fig. 2, filament 2a, 2b extend out in fluorescent tube 1, and two seal wires of Lian Jieing are merged into terminals respectively, connect on circuit again.
Claims (2)
1. the electricity-saving lamp that is difficult for the disintegration of filament, form by fluorescent tube (1), filament (2a, 2b), electric capacity (3,4) and choke (5), it is characterized in that: lamp (2a, 2b) extends out in fluorescent tube (1), be connected with two seal wires respectively, in two seal wires that each filament connected, one is connected with circuit, another root is idle, electric capacity (4) is positioned between two filaments (2a, 2b), and the one end links to each other with electric capacity (3), and the other end links to each other with choke (5).
2. the electricity-saving lamp that is difficult for the disintegration of filament according to claim 1 is characterized in that: filament (2a, 2b) extends out in fluorescent tube (1), and two seal wires of Lian Jieing are merged into terminals respectively, connect on circuit again.
