Description

The two-part lamp dimmer

The utility model relates to a kind of device that can regulate lamplight brightness automatically in the power technology, refers in particular to a kind of chared thermal type infrared lamp light control device.

Usually utilize in the lamp dimmer of chared thermal type infrared element, it mostly only is simple light controlled function, utilize the brightness of the extraneous light of light-sensitive element CDS (cadmium sulfide conductive material) induction, the light on and off of infrared inductor (PIR) control lamp, and by the trigger mode of a plurality of ON-OFF control circuit, as automatic mode, test pattern and on-mode etc., multiple trigger mode is provided, select to use by the user.When night, nobody went to trigger infrared inductor, this bulb just can be not shinny, therefore when night, there is no the function of guidance lighting, and the each side such as simple and easy degree of its circuit structure, product stability, fabrication yield and assembling are all desirable not to the utmost.

The purpose of this utility model is to propose a kind of two-part lamp dimmer of mainly being made up of an infrared inductor, an integrated circuit, a power circuit, a complete bright angle controller, half bright angle controller, trigger triode TRIAC circuits for triggering and an osram lamp, it makes light shinny slightly responding to automatically at dark, when sensed the people near the time, can make the light degree output of light, can not only energy savings, and can get rid of the dead angle at night, thereby solve the existing in prior technology problem.

The technical scheme that the utility model adopted is that it mainly is made up of an infrared inductor, an integrated circuit, a power circuit, a complete bright angle controller, half bright angle controller, trigger triode TRIAC circuits for triggering and an osram lamp.Wherein, the inside of integrated circuit includes an amplifier, places judging circuits, triggers output circuit, a timer and an external light source testing circuit surely.

This external light source testing circuit is to utilize an external light-sensitive element CDS to detect the luminosity of external environment, when extraneous brightness is too bright, no matter whether infrared inductor detects the people near all can be not shinny; When the external world is dim, this external light source testing circuit is promptly exported a signal to half bright angle controller, make it export a signal to the TRIAC circuits for triggering, osram lamp will send a little bright light, this external light source testing circuit is also exported a signal to triggering output circuit simultaneously, to wait for the detected signal of infrared inductor at any time, whether this infrared inductor is to respond to have the people close, and the amplifying circuit that this signal is input in the integrated circuit amplifies, again via position circuit judges surely to give false action-proof.Its input of accurate places judging circuits is PIR through the signal that amplifier produced, if its output no-output is represented promptly that PIR does not have and is detected extraneous movable signal, when PIR detects extraneous movable signal, its output will transfer high potential to by electronegative potential, and this standard position is input to the triggering output circuit.The prerequisite that this triggers the output circuit output signal must be detected the information of extraneous light dark by the external light source testing circuit, exports timer to otherwise will not have any signal.This timer is to be set at a ultrared sensitive time, and outputs to complete bright angle controller, to trigger the TRIAC circuits for triggering, makes osram lamp send a complete bright light; When infrared ray after the sensitive time, promptly be returned to little bright state.Wherein said timer is an external time control circuit, and regulates the time by a variable resistor; And said power circuit, can be connected in series a switch therein, this switch is as the commutation circuit mode of operation; As automatic mode, test pattern and on-mode.

Advantage of the present utility model is: the first, can respond to automatically at dark make light slightly shinny when sensed the people near the time, even light with the brightest luminosity output, but energy savings not only and can be got rid of dark dead angle, giving and preventing the generation of committing a crime; The second, owing to the utility model is mainly gone out by the point that the controller of an integrated circuit is controlled light, so the convenience of using is provided; The 3rd, because the circuits for triggering that the utility model is made up of TRIAC and DIAC (diac) are little bright or bright entirely with control light, therefore have the function of illumination indication.
