  • LED BRACKET, LIGHT-EMITTING UNIT, AND LIGHT-EMITTING ASSEMBLY
    Publication number: 20240047623
    Abstract: The present application relates to an LED bracket, a light-emitting unit and a light-emitting assembly. A substrate of the LED bracket comprises a substrate main body, and a supporting part extending from the substrate main body into a side wall of a bowl portion of the LED bracket, wherein the supporting part extends from one conductive area to the other conductive area in the side wall of the bowl portion of the LED bracket, and at least extends to a side wall area corresponding to an insulating area on the side wall that insulates and isolates the two conductive areas.
