Abstract
The utility model relates to a novel incandescent lamp which belongs to the application field of the electronic technology. A rectifying filtering circuit is arranged in a lamp bulb circuit and is composed of rectifying diodes D1, D2, D3, D4 and a capacitor C, the power supply is respectively connected with the negative electrode of the D1, the positive electrode of the D2, the negative electrode of the D3 and the positive electrode of the D4, a lamp bulb is respectively connected with the positive electrodes of the D1 and the D3 and the negative electrodes of the D2 and the D4, and the filtering capacitor is connected in parallel with the lamp bulb. Because of installing the rectifying filtering circuit, the alternating current flowing through the lamp bulb is changed into the direct current with minimal fluctuation, and meanwhile, the voltage peak value is also slightly reduced. Thereby, the problem that the alternating current impacts the lamp bulb is solved, and the service life of the lamp bulb is prolonged. The utility model has the advantages of reasonable design, easy manufacture, low cost and reliable operation, and effectively prolongs the service life of the lamp bulb.
Description
(1) technical field
The utility model relates to a kind of incandescent lamp, belongs to the application of electronic technology technical field.
(2) background technology
Existing incandescent lamp needs the public arena of long-time illumination because the fluctuation of power supply reduces the life-span of bulb greatly at some, and some months even will change bulb in several days a time was both wasted, and was inconvenient again.Public occasions such as the corridor that has have at present been installed the acoustic control bulb, but fundamentally do not solve the shock problem of voltage fluctuation to bulb; A kind of patented technology is arranged, provide a kind of two-burner lamp bulb, two bulb parallel connections, though solved the bulb life problem, lamp socket manufacturing process complexity has also increased illumination cost.
(3) summary of the invention
At the deficiencies in the prior art, the utility model provide a kind of reasonable in design, easy to manufacture, with low cost, use incandescent reliable, that can effectively prolong bulb service life.
A kind of incandescent, a current rectifying and wave filtering circuit is installed in bulb circuit, current rectifying and wave filtering circuit is made up of rectifier diode D1, D2, D3, D4 and capacitor C, the negative pole of the negative pole of D1, the positive pole of D2 and D3, the positive pole of D4 are connected with power supply respectively, the negative pole of the positive pole of D1, D3 and D2, D4 is connected with bulb respectively, and filter capacitor C is in parallel with bulb.
The current rectifying and wave filtering circuit mounting means can adopt one of following manner: (1) current rectifying and wave filtering circuit is installed in the lamp holder of bulb; (2) current rectifying and wave filtering circuit is installed in the lamp socket; (3) current rectifying and wave filtering circuit is installed on the indoor illuminating line.
The utility model makes the alternating current that flows through bulb become the minimum direct current of fluctuation because current rectifying and wave filtering circuit has been installed, and voltage peak also slightly reduces simultaneously, thereby has solved the shock problem of alternating current to bulb, has prolonged the useful life of bulb.The utlity model has advantage reasonable in design, easy to manufacture, with low cost, that use reliably, can effectively prolong bulb service life.
(4) description of drawings
Accompanying drawing is a structural representation of the present utility model.
Wherein, D1, D2, D3, D4: diode, C: filter capacitor, R: bulb.
(5) embodiment
Embodiment: structure of the present utility model as shown in drawings.A current rectifying and wave filtering circuit is installed in the lamp holder of bulb, current rectifying and wave filtering circuit is made up of rectifier diode D1, D2, D3, D4 and capacitor C, the negative pole of the negative pole of D1, the positive pole of D2 and D3, the positive pole of D4 are connected with power supply respectively, the negative pole of the positive pole of D1, D3 and D2, D4 is connected with bulb respectively, and filter capacitor is in parallel with bulb.The withstand voltage 400V that is of diode D1, D2, D3, D4 and capacitor C.
