Abstract

The invention discloses a carrier and a light-emitting device, which belong to the field of lighting. The carrier includes an integrally formed substrate and the substrate includes opposing top and bottom surfaces. A box dam is arranged on the top surface of the substrate in a protruding mode, the top surface is provided with an inner side area and an outer side area which are arranged on the twosides of the box dam, the inner side area is provided with a plurality of protruding columns arranged on the top surface in a protruding mode, and each protruding column is provided with a groove formed in the bottom surface. The substrate has an outstanding heat conduction effect, so that thermal quenching can be effectively avoided after the substrate is applied to the light emitting diode.

Description

technical field [0001] The present application relates to the lighting field, in particular, to a carrier and a light emitting device. Background technique [0002] Chip On Board (COB for short) is to adhere the bare chip on the interconnection substrate with conductive or non-conductive adhesive, and then wire bonding to realize electrical connection. Light-emitting diodes based on board chips are also called COB LEDs, and are widely used because of their characteristics. [0003] COB LEDs can be implemented in two ways as described below. [0004] Firstly, the light-emitting chip is arranged on the circuit layer of the substrate, and then a circle of plastic encapsulant is pressed on the periphery of the light-emitting chip to form a dispensing area of ​​phosphor glue. [0005] Second, on the substrate, draw a circle of white silica gel as a dam through a glue dispenser, and then arrange LED chips in the area inside the dam and dispense phosphor glue. [0006] With the ...
