Abstract: The present disclosure provides a LED lighting device, a LED lamp, and a LED display screen. The LED lighting device includes: a plurality of LED lighting units placed in a heat sink; the plurality of LED lighting units is packaged with at least one phosphor. That is, by using the LED lighting units to package the same phosphor or package a plurality of phosphors, the light color and even the color of the mixed light of the LED lighting units can be easily controlled, thus solving the problems of the traditional technology.

Abstract: Disclosed are an LED light source apparatus, a lighting device, and a lighting control method. The LED light source apparatus includes a plurality of light mixing units. Each light mixing unit comprises LED chips of at least four colors, and the at least four colors at least include red and green. The plurality of light mixing units is uniformly distributed on a bearing surface along a ring.

Abstract: An LED light device and a circuit preparation method thereof are provided. The LED light device includes a base, an LED light unit, and a lamp shade. The LED light-emitting unit and the lamp shade are arranged on the base. The lamp shade covers the LED light-emitting unit inside. The circuit preparation method includes following steps of: providing a base which is a physical entity having a three-dimensional structure on the surface thereof; coating a circuit layer on the base surface through a programmable coating equipment, manual coating or the combined mode, wherein the circuit layer is a liquid or powder coating containing metal materials, and the thickness of the circuit layer is 20 ?m or more; baking the base coated with the circuit layer at the high temperature of 100-1,000° C. until the circuit layer is dried; and obtaining a base having a three-dimensional circuit after cooling.

Abstract: The invention relates to a display apparatus, particularly to structure of LED display modules. The invention could be implemented through a LED matrix display module with high luminance area ratio comprising an injection molding unit and a printing board fitted therewith, wherein, LEDs are regularly arranged in a matrix on said printing board, and each pixel dot is correspondingly provided with a reflecting cavity on said molding unit, with the reflecting cavity expanding gradually from the inside section (close to the display surface). The circumference of the inside section of the reflecting cavity forms a closed and smooth circular curve. The invention is characterized in that, the circumference of the outside section of the reflecting cavity forms a closed and smooth curve which is a square with round corners, and the side face of the reflecting cavity is a smooth and cured surface.
