Description

This application relates to the field of LEDs (Light Emitting Diodes, LED chips), and more particularly to LED brackets, light-emitting units, and light-emitting assemblies. Chip LEDs are widely used in fields such as lighting, decoration, backlighting, and displays. A chip LED includes an LED bracket and an LED chip mounted on the LED bracket. Conventional chip LED brackets typically include a substrate and a package mounted on the substrate, with a bowl-shaped cup formed within the package to house the LED chip. However, the side walls of the bowl-shaped cup in conventional LED brackets have low strength and are therefore prone to breakage due to external forces, such as distortion of the sheet metal. Therefore, improving the strength of LED brackets is a technical problem that needs to be solved urgently.
