Problems solved by technology

[0003] However, there is no ultra-fine-pitch high-density LED device product that integrates the two functions of projection lighting.
The reasons can be attributed to the following two points: one is that the size of the LED chip is small and the integration level is high, so the requirements for the packaging process and technology are very high, so that the ultra-fine-pitch LED array module is still in the sample development stage; the other is the projection lighting. The concept has been around for a long time, but the research on LED projection lighting is just in its infancy, so there is little in-depth research on devices that combine high-density LED projection with lighting

Description

technical field [0001] The invention belongs to the technical field of LED projection and lighting, and in particular relates to an LED projection lighting device. Background technique [0002] LED is called a green light source, which has the characteristics of energy saving, environmental protection, long life, small size, etc., and can be widely used in various display, decoration, backlight, general lighting and urban night scenes and other fields. In recent years, some economically developed countries in the world have launched fierce technical competition around the development of LEDs. Over the years, LED lighting has been valued by the state and governments at all levels due to its energy-saving and environmental protection advantages. Various localities have introduced relevant policies and measures to speed up the development of LED lamps, laying a good foundation for further popularization of LED. Most of the existing LED applications are in the lighting field, a...
