Abstract
The utility model discloses a voltage adjusting switch for a lamp. The voltage adjusting switch for a lamp uses a structural design which is different from the prior art, and comprises a switching element which is connected with a rectifying diode; the connected diode and the switching element are connected to a commercial power line with a lighting lamp, and the switching element is combined with the rectifying diode. With the advantages of simple structure, and low manufacturing cost and selling price, the utility model can effectively prolong the service life of lighting lamps and save expenses.
Description
The utility model relates to the switching device in the power technology, is a kind of servicing unit that is used for illuminating lamp, specifically, is a kind of illuminating lamp voltage-regulating switch unit.
Lighting bulb damages operate as normal, the studying and living that usually influences people, bring all inconvenience and worry to people, especially the place that needs long-time illumination in staircase, corridor etc., the frequent damage of bulb and need to change give inconvenience that people brought and worry more very, reluctantly, people have to several bulbs of over-bought in order to the usefulness of replacing.If you just do not have the backup bulb on hand again when bulb damages suddenly, that have to have been groped in the dark.Even you have the backup bulb, replaceable bulb is not light thing yet, and what particularly use when your parlor, bedroom, passageway is ceiling light, and that not only can be more fragile because of its outside glass lamp shade poor radiation, and it is also bigger to change difficulty.
The purpose of this utility model provide a kind of simple and reliable for structure, help preventing that lighting bulb from often burning out, prolonging the illuminating lamp tap changer of bulb service life.
Technical solution of the present utility model is: a kind of illuminating lamp tap changer, it has adopted and has been different from the prior art constructions design: comprise a switch element, switch element is connected with a rectifier diode, diode that is connected and switch element and illuminating lamp are with being connected in the line, and switch element and rectifier diode are combined into one.
Switch element described in the utility model adopts hand switch.Certainly, also can adopt other suitable switch elements.
Rectifier diode described in the utility model and switch element be assembled in the housing or both plastic packagings together.Certainly.Also can adopt other suitable versions.
The utility model has the advantages that: simple and reliable for structure, manufacturing cost and price is cheap, can effectively prolong useful life of illuminating lamp, cut down expenses.The consumer is acceptant.
Below in conjunction with drawings and Examples the utility model is further described:
Accompanying drawing is the circuit structure diagram of a kind of illuminating lamp tap changer of the present utility model.
Accompanying drawing has been described an embodiment of the present utility model.A hand switch K is arranged in this embodiment, hand switch K is connected with a rectifier diode D (can select 2CZ57F type diode for use), rectifier diode D that is connected and hand switch K and lighting bulb S be with being connected in the 220V line, and hand switch K and rectifier diode D are assembled in interior or both plastic packagings of a housing together.
Basic principle of the present utility model is: when the positive half cycle of AC power, rectifier diode D conducting, because of the forward equivalent resistance Ri of diode less, so the positive half cycle waveform of voltage waveform on the bulb S and supply voltage is basic identical, during negative half period, diode D ends, and the electric current in the bulb is zero, and the pressure drop on it also is zero.So, the mains voltage variations one-period, what obtain on the bulb S is the sinuous pulsation voltage of half period, (0-2 π) its mean value is 100V in one-period exchanging.This shows that because alternating current is carried out halfwave rectifier, objectively diode has played the pressure regulation effect, the voltage that is added on the bulb S is descended significantly, thereby reduced the working temperature of osram, the spoilage of bulb is reduced greatly, prolonged the useful life of bulb to a great extent.
