Abstract
The utility model relates to a light stepwise changing controller, which belongs to an electronic control light modulating device. The light stepwise changing controller is composed of a transformer, a rectification circuit, a filter circuit and a control circuit, wherein, the control circuit is composed of a staircase generator, an integral circuit, a comparator, a drive and coupled circuit and a controlled silicon. The light stepwise changing controller can control the luminance of lamp light to automatically gradually change from dark to bright; the light stepwise changing controller provides the adaptation time of strong light for eyes of a person, consequently plays the protective action on eyes, and is widely suitable for occasions such as families, hospitals, etc.
Description
The utility model relates to a kind of gradually bright control device of light of incandescent lamp, belongs to Electronic Control light regulating technology field.
The employed incandescent lamp of present most of family or office, when with the switch connection power supply, light reaches the high-high brightness of bulb at once, and eyes often feel under the weather, and especially turn on light at midnight, more feel dazzling.Though there is lamp dimmer to come out on the market, rotate light-control knob with hand, make bulb brightness ascending, use little convenience.People are seeking a kind of eyesight is had protective effect, and euphorosia does not have the new type light source of light stimulus.
The purpose of this utility model is to overcome above-mentioned shortcoming and provides a kind of light light gradually controller, it adopts electronic circuit to control ordinary incandescent lamp automatically, when people open light switch, the brightness of light is brightened gradually by moving secretly, adaptation time to high light is provided for people's eyes, thereby makes people that a kind of natural, comfortable impression be arranged.
Technic relization scheme of the present utility model can be described below by drawings and Examples:
Fig. 1 is a composition block diagram of the present utility model
Fig. 2 is each part waveform relationship figure of the present utility model
Fig. 3 is the utility model circuit theory diagrams
Input termination 220V AC power of the present utility model as seen from Figure 1 is through transformer (1) output 9V alternating voltage (A), obtain forward all-wave synchronizing voltage (B) with the 220V AC synchronous through rectification circuit (2), the one tunnel after filter circuit (3) filtering output dc voltage (D).Another road is delivered to shaping circuit (4) output square wave (C) with (B) and is delivered to staircase generator (5) again, the trapeziodal voltage (E) that produces, with the integral voltage (F) of integrating circuit (6) output deliver to comparator (7) relatively after, produce the different square wave (G) of width by the angle of flow that drives, coupling circuit (8) is controlled controllable silicon (9), thereby change the brightness of load (being bulb).Each waveform relationship figure partly of circuit as shown in Figure 2.
