Embodiment Construction

[0017] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0018] see figure 1 , the timing control circuit of the present invention generally includes: a processor circuit 1 and a zero-crossing detection circuit 2 connected to the processor circuit 1, an output control circuit 3, a button input circuit 4 and a liquid crystal display circuit 5, and There is a power supply circuit 6 that provides working energy for the above functions. The instruction information provided by the processor circuit 1 by means of the liquid crystal display circuit 5 can set and save at least one lighting period of the lamp and the corresponding lamp according to the time setting signal and the brightness setting signal of the lamp provided by the key input circuit 4. Luminous brightness; the processor circuit 1 can output a control signal to the output control circuit 3 to turn on / off the controlled lamp when the start time / end of the set lighti...

Abstract

Provided is a timing control circuit and a lamp. The timing control circuit comprise a processor circuit, a zero cross detection circuit which is connected with the processor circuit, an output control circuit, a key input circuit and a liquid crystal display circuit, wherein at least one lamp lightened time interval and corresponding lamp luminance are set and stored by the processor circuit with the help of the liquid crystal display circuit according to a time set signal and a lamp luminance set signal provided by the key input circuit, a control signal which can lighten or extinguish the controlled lamp is output by the processor circuit to the output control circuit with the help of an internal clock in the processor circuit from starting time to termination time of the set lamp lightened time interval, and the control signal which can enable luminance of the controlled lamp to be corresponding to the set lamp luminance is further adjusted according to the set lamp luminance combined with a zero cross detection signal which is provided by the zero cross detection circuit. The timing control circuit and the lamp have the advantages of being capable of flexibly controlling timed opening and closing of the lamp and luminance of the lamp.

Description

technical field [0001] The invention relates to the field of lamps, in particular to a timing control circuit and a lamp using the timing control circuit. Background technique [0002] At present, energy saving and emission reduction has become a common topic in the world, and saving electric energy is one of the most intuitive and common measures for energy saving and emission reduction. In street lighting or architectural lighting, the loss of electric energy can be reduced by improving the electro-optical conversion efficiency of the lamps. At the same time, the switching time and brightness of the lamps can be reasonably controlled to save electric energy. In order to avoid the situation of always-on lamps, existing lamps are equipped with special timing control circuits to limit the lighting time of lamps. The existing timing control circuit is usually implemented by a mechanical timing switch. By operating the timing knob and according to the corresponding scale on th...
