Abstract

Provided is a light-emitting diode packaging module. The light-emitting diode packaging module comprises a circuit board, a metal plate, a plurality of chips, a plurality of wires and a packaging material, wherein the metal plate is used for directly covering the upper surface of the whole circuit board, the metal plate is provided with a plurality of chip bearing seats and a plurality of openings formed in a routing area which enables the circuit board to expose, the plurality of openings are arranged on the sides of the plurality of chip bearing seats in an adjoining mode, the plurality of chips are respectively arranged on each chip bearing seat, the plurality of wires are electrically connected with the chips and the routing area of the circuit board, and the packaging material is used for respectively covering each chip, the plurality of wires and the routing area.

Description

technical field [0001] The invention relates to a light emitting diode packaging technology, in particular to a light emitting diode packaging module utilizing chip on board (COB) technology. Background technique [0002] Because light-emitting diodes (light-emitting diodes, LEDs) have the characteristics of long life, power saving, and durability, LED lighting devices are a trend of green energy and environmental protection, and will be widely used in the future. In general high-brightness LED lamps, a light-emitting module that usually includes several LED bulbs is directly welded on a general circuit board or an aluminum substrate. In order to increase the heat dissipation effect, additional heat dissipation components are designed, such as heat dissipation fins are arranged under the substrate. However, in addition to the problem of heat dissipation, most LED lamps emit light in a straight direction, which cannot achieve the effect of emitting light at 270 degrees like ...
