Abstract
The invention relates to an incandescent light starting device with voltage reduction and time delay functions. The incandescent light starting device comprises 220V alternating-current power, a power switch, a full-bridge rectifying circuit, a load circuit, a voltage reduction and time delay circuit, a unidirectional silicon controlled rectifier and a triggering circuit of the unidirectional silicon controlled rectifier. According to the invention, after the power switch is connected with the 220V alternating-current power, a filament of an incandescent light emits dark light due to low voltage application and filament thermal resistance and is preheated, after 30 seconds, the filament of the incandescent light gradually acquires the full voltage of the 220V alternating-current power and emits light in a full power manner, so that the phenomenon that the filament of the incandescent light is easily broken in a flashing manner because the full voltage and large current of the 220V alternating-current power is applied to the filament of the incandescent light in a cold state is effectively avoided, thus, not only is the service life of the incandescent light prolonged favorably, but also the eyes of people getting up at deep night are prevented from stimulation caused by strong light.
Description
Technical field
The invention belongs to the application of electronic technology field, relate to a kind of incandescent lamp starting drive that the step-down delay function is arranged.
Background technology
Used the people of incandescent lamp that such experience or cognition were all arranged; That is exactly that the filament of incandescent lamp is blown majority and occurs in the moment of connecting the 220V alternating current; Especially open incandescent lamp suddenly at night, the filament of incandescent lamp is easy to blowing by high voltage in the late into the night; Moreover be to get up night in the time of need opening incandescent lamp, under the environment of dark, people's eye pupil is relatively big, and the light of at this moment turning on light very obviously makes the eyeball that can't keep one's eyes open to the stimulation of eye.Though incandescent lamp does not belong to energy-saving lamp, because of its price is very cheap, use very convenient, so the incandescent lamp effect that still has the common energy-saving lamp tool to be difficult to substitute in some place at present.
