Abstract

The utility model provides a novel light-operated device. The structure is as follows: the lighting lamp control circuit is characterized in that a controller DM is connected in series with a power supply circuit of the lighting lamp, the base electrode of the triode is connected to the photoresistor, the collector electrode of the triode is connected to the resistor and the controller DM respectively, the emitter electrode of the triode is connected to the controller DM, and the photoresistor and the resistor are connected to the controller DM respectively. When the ambient light intensity is larger, the internal resistance of the photoresistor is small, at the moment, a larger current passes through the photoresistor to enable the triode to be in saturated conduction, after the triode is saturated, the voltage of the a end of the controller DM is far lower than 1.6V, so that the inside of the controller DM is cut off, and the illuminating lamp cannot be lightened. When the ambient light becomes dark gradually, the luminous flux irradiated on the photoresistor is weakened, the internal resistance of the photoresistor becomes larger and larger, and the internal circuit of the controller DM is also gradually switched on, so that current passes through the illuminating lamp to enable the illuminating lamp to emit light. The utility model discloses what make the filament can the gradual change formula passes through to the incandescent state by red to be difficult for producing the scintillation when the red filament.

Novel light-operated device

Technical Field

The utility model relates to an illumination control technical field, concretely relates to novel light-operated device.

Background

The lighting control is a technology for controlling and managing the on, off, regulation, combination, scene mode and the like of a light source by adopting an automatic control technology and an intelligent management technology so as to achieve the purpose of specific lighting effect or energy conservation. The lighting control technology mainly comprises a field bus technology, a dimming control technology, a power pulse communication and control technology, a wireless control technology and the like.

Controlling the light source on and its brightness according to the ambient light intensity is a common lighting control project. In the prior art, the function is generally realized by sensing the ambient light intensity by using an illumination sensor, and when the ambient light intensity reaches an illumination threshold value, a control signal is sent to a power supply circuit of a light source to enable the light source to be turned on or turned off. Although this mode can respond according to the ambient light intensity, the light source cannot be turned on or off in a gradual manner, and the filament is likely to flicker before reaching the incandescent state (i.e., the red state).

Disclosure of Invention

The utility model discloses aim at to prior art's technical defect, provide a novel light-operated device to solve the technical problem of the unable gradual change formula of conventional light-operated device and open the light source.

The to-be-solved technical problem of the present invention is that, when the conventional light control device is turned on, the filament is in the red state and the flicker phenomenon is easy to occur.

In order to realize the technical purpose, the utility model adopts the following technical scheme:

the utility model provides a novel light-operated device, includes the light, controller DM, the triode, the photo resistance, the resistor, wherein, it has controller DM to establish ties on the supply circuit of light, and the base of triode is connected to the photo resistance, and the collecting electrode of triode is connected to resistor and controller DM respectively, and the projecting pole of triode is connected to controller DM, and photo resistance and resistor are connected to controller DM respectively.

Preferably, the controller DM is a DM1205 controller.

Preferably, the resistor is an R470 resistor.

Preferably, the transistor is a 3dk4 transistor.

In the above technical solution, the photoresistor may be referred to as a photoresistor RG or RG for short, the transistor may be referred to as a transistor VT or VT for short, the lighting lamp may be referred to as a lighting lamp H, and the controller DM may be referred to as DM for short, which is described herein.

The working principle of the utility model is as follows: in the daytime, because the illumination is strong, the internal resistance of the photoresistor RG is small, at the moment, a large current passes through the RG to enable the triode VT to be in saturated conduction, after the VT is saturated, the voltage of the a end of the controller DM is far lower than 1.6V, so that the inside of the DM is cut off, and the illuminating lamp H cannot be lightened. At night, light becomes dark, luminous flux irradiated on the RG is weakened, internal resistance of the RG becomes larger and larger, an internal circuit of the controller DM is also gradually switched on, and therefore current passes through the illuminating lamp H to enable the illuminating lamp H to emit light. The circuit is in a soft start mode, namely the filament of the illuminating lamp H is gradually transited to an incandescent state from red, and the flickering phenomenon is not easy to generate when the filament is red.
