Illumination control device and method

Abstract

The invention discloses an illumination control device, which comprises a first circuit and a second circuit that are connected in parallel, wherein the first circuit is provided with a light-operated switch and a first relay which are connected in series; the second circuit is provided with a first normally-closed switch, a starting switch and a second relay which are connected in sequence and in series and matched with the first relay, and the second circuit is further provided with a conversion switch connected with the normally-closed switch in parallel and a first normally-opened switch matched with the second relay. The illumination control device provided by the invention is provided with the circuit matched with the light-operated switch, and realizes multiple control modes of illumination, comprising an automatic control mode and a manual control mode; the light-operated switch cannot be influenced when being in the automatic control mode; and in cloudy days, the conversion switch is converted into the manual control position to realize that an illumination device is normally brightened, so that frequency starting is not needed and the service life of the illumination device cannot be influenced.

Description

technical field [0001] The invention relates to the technical field of lighting control, in particular to a lighting control device and a control method thereof. Background technique [0002] Lighting is a measure of using various light sources to illuminate working and living places or individual objects. The use of the sun and sky light is called natural lighting; the use of artificial light sources is called artificial lighting. The primary purpose of lighting is to create good visibility and a pleasant environment. [0003] General factory lighting needs artificial lighting because of the need to carry out operations and production in the workshop. The workshop has very high requirements for lighting. Workers need sufficient lighting when operating machine tools. The lighting can be used to see the road clearly to prevent tripping or bumping. Of course, the power consumption of factory lighting is also huge, so some energy-saving measures are generally adopted. At pres...

[0003] General factory lighting needs artificial lighting because of the need to carry out operations and production in the workshop. The workshop has very high requirements for lighting. Workers need sufficient lighting when operating machine tools. The lighting can be used to see the road clearly to prevent tripping or bumping. Of course, the power consumption of factory lighting is also huge, so some energy-saving measures are generally adopted. At present, there are illuminance-adjustable light-controlled switches used in factory lighting. It only has an automatic control mode. When the illuminance in the workshop meets the requirements, the switch is automatically turned off. When the illuminance in the workshop cannot meet the requirements, the switch can be adjusted and controlled according to the actual needs of the illuminance. However, when this switch is actually used, If you encounter cloudy conditions, the sun appears and disappears frequently, and the switching action will be performed frequently, and it needs to be turned on manually after it is automatically turned off, which will have a serious impact on the life of the lighting device.
