From the 1990s to the present, the research and development of LED plant light chip and material production technology has made great progress, from Chendi trapezoidal structure to the surface structure of the arts and sciences, and then to the flip chip structure of the chip.
High-brightness blue, green, yellow, orange, and red LED plant light chip products have come out one after another. Since the beginning of the 21st century, they have been widely used in the field of special lighting with medium and low luminous flux.
The widespread use of LED products has made them receive unprecedented attention in the field of lighting. While driving social progress, they have also promoted their own development. The use of different packaging structures and sizes, different light-emitting colors and multi-color combinations, derives Multi-directional and multi-series products, LED plant lights are one of its important products.
The types of LED plant light packaging structures are also constantly enriched and improved, and can be classified according to different characteristics such as luminous color, luminous brightness, chip material, size and so on.
A single LED plant light chip generally constitutes a point light source, and multiple chips can be assembled together to form a line light source (such as an LED plant light bar) and a surface light source (such as an LED panel plant light). In terms of indication and reality, the light-emitting display also uses multiple LED chips, which are combined with appropriate optical structures through the appropriate connection of the LED chips, to form the light-emitting points and light-emitting lines of the light-emitting display.
Surface mount LEDs have gradually replaced pin-type LEDs, with more extensive applications and higher flexibility, and are also the direction of vigorous development of the LED display market.
At present, LED packaging methods mainly include COB, wafer-level packaging, COF integrated packaging, modular integrated packaging and so on. COB occupies a leading position in the current packaging market with its low cost advantages. The main advantages of modular integrated packaging are standardized production, material saving, convenient maintenance, cost reduction and many other advantages. It is a chip for LED plant lights and other LED products. The main direction of the package.
