For LED technology, the situation has become more diverse. There is a product level chain, and the industry assigns them the following numbering:
Level 0: LED chips Horizontal 1: LED packaging, allowing for welding and cleaning outside of indoor environments. For white LED packaging, there is a phosphor material inside that converts the blue light of the chip into other wavelengths to generate white light Level 2: Basic LED module, including one or more LED packages on a printed circuit board Level 3: An LED module with extended functionality, typically consisting of a Level 2 board with additional features that allow for mechanical installation, electrical connection, or photometric effects. The additional features presented depend on the product type and may include some or all electronic control devices required for the operation of LED modules Level 4: Luminaires, LED products used in applications
