Description

Technical field: [0001] The invention relates to the technical field of light-emitting diodes (LEDs), in particular to an LED lamp panel structure with a patch bracket and a production process thereof. Background technique: [0002] Light-emitting diode (LED) is a semiconductor solid light-emitting device. It uses a solid semiconductor wafer as a light-emitting material. When a forward voltage is applied to both ends, the carriers in the semiconductor recombine to cause photon emission to generate light. It is the most The popular light source technology, the characteristics of LED light source are: energy saving: energy consumption is reduced by 80% compared with incandescent lamps with the same light effect; using low voltage power supply (between 6-24V), good safety; small size, can be prepared into various Shaped devices; long life; fast response time: the response time of incandescent lamps is milliseconds, and the response time of LED lamps is nanoseconds; no harmful m...

Problems solved by technology

[0003] Referring to Fig. 1, the current light-emitting diode or LED lamp is composed of a two-legged support 1 (or positive and negative pins) and a chip 2 in a bowl on the support 1, covering the fluorescent powder on the chip 2. 4 and the epoxy resin 5 that encapsulates the chip 2, the chip 2 is connected to the support 1 through its positive and negative lead wires 3 respectively, its disadvantages: one is that the support 1 is a wire support, and its thermal conductivity is poor, and the light and heat emitted by the chip 2 make Phosphor powder 4 accelerates aging, which leads to poor color temperature stability of white light diodes and reduced product life; second, mechanized production cannot be realized. General LED light panels are composed of multiple LED light monomers. When producing LED light panels, It is necessary to manually insert the positive and negative pins 1 (two or four) of the LED lamp unit into the socket of the circuit board, and then manually solder. Such a production method will easily lead to unstable product quality and low yield. , the production efficiency is low, and the production cost is high; the third is that a gold-plated layer is provided at the connection of the positive and negative electrodes on the support 1 for good welding quality and heat conduction, but the heat dissipation effect of the support 1 is limited because of the limited heat dissipation area. Gold plating further increases production costs
