Description
Technical Field
The project development of a rear projection flat lamp capable of switching color temperatures is a technical development for realizing switching of different color temperatures of the same lamp.
Background
At present, lighting lamps on a ceiling grid of an indoor office are almost single-color temperature side-emitting or rear-projection flat lamps, color temperature switching and changing cannot be carried out, however, terminal users in many high-end lighting places prefer that the color temperature of the lamps change along with sunlight in different time periods, and secondly, a plurality of terminal sales companies or agents desire that the same lamp can cover multiple color temperatures, so that the stock of the lamps increased due to different color temperatures can be reduced. Therefore, the rear projection flat lamp capable of switching the color temperature has research value from the economic benefit of reducing the stock in the aspects of the demand of terminal customers on the lighting effect and the sales links.
SUMMERY OF THE UTILITY MODEL
The invention relates to a rear projection flat lamp capable of switching color temperature, which is mainly designed in that the same lamp uses two LED lamp beads of low color temperature and high color temperature, and different currents are supplied to the LED lamp beads of different color temperatures through a certain circuit design to achieve the switching change of the color temperature.
