Abstract
The invention provides a starlight lamp and a starlight control method. An intelligent control board is used for dividing gray scales for light source luminance, each gray scale progressively changes according to a ratio, meanwhile, each light source in a light source group gradually brightens from darkness and gradually darks from lightness so as to carry out cyclic change through a way that a serial port carries out shifting sending on grey display data. Through the shifting sending way, the total luminous flux of a lamp is almost kept constant while each light source changes so as to guarantee that an illumination effect of the starlight lamp is the same with the illumination effect of a common lamp under a situation that an illuminated exhibit does not have a high light reflecting surface, the problems of noise, vibration and service life of a rotary illumination lamp of a mechanical structure are solved, a cabinet lamp also has a lamp rotation effect without the help of mechanical rotation, and meanwhile, the user does not feel uncomfortable while the grey display of progressive change causes the flicker of the light source to own outburst feeling.
Description
technical field [0001] The invention relates to the lighting field of display cabinets, in particular to a starlight lamp and a control method for the starlight lamp. Background technique [0002] At present, display cabinet lamps are widely used, and some display cabinet lamps use rotating lighting lamps to make commodities such as jewelry shine and reflect the noble value of commodities. However, such mechanically rotating lamps with complex structures will have side effects such as sound and vibration. Contents of the invention [0003] The object of the present invention is to provide a starlight lamp, which solves the problem that the display cabinet lamps in the prior art realize rotary lighting by mechanical rotation. [0004] Another object of the present invention is to provide a method for controlling a starlight lamp. [0005] The technical solution adopted by the present invention to solve its technical problems is: [0006] A starlight lamp, comprising a bo...
