LED lamp with bonding pads of driving board or connection board and bonding pads of aluminum substrates being in butt welding connection

Abstract

The invention discloses an LED lamp with bonding pads of a driving board or a connection board and bonding pads of aluminum substrates being in butt welding connection. The LED lamp comprises the driving board (1) or the connection board (1) and the aluminum substrates (4), wherein the aluminum substrates are provided with lamp beads (3); the driving board or the connection board is provided with the bonding pads (2) connected with the direct current output ends; the aluminum substrates are provided with the bonding pads which are consistent with and correspond to the bonding pads on the driving board or the connection board in position, shape and size in a mirroring mode; the two kinds of bonding pads are attached tightly face to face through the tin spraying process, the bonding pads are fused into a whole through locating and heating, the bonding pads are combined into a whole due to fusion and solidification of soldering tin on the upper faces of the bonding pads, and consequently the aluminum substrates and the driving board or the connection board are combined into a whole. The aluminum substrates and the driving board or the connection board are connected together, the connection process is simplified, man-hour cost and connection conductor materials are saved, production efficiency is improved, and manufacturing cost is lowered.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED lamp in which a driving board or a welding pad of a connection board is butt-welded with an aluminum substrate welding pad. Background technique [0002] LED lamps are entering the market with a strong momentum, because of their high luminous efficiency, green environmental protection and long service life, they are deeply loved by people. However, the heat dissipation problem caused by point light emission and concentrated light emission is still a problem that LED lights must solve generally. Various connection methods connect the aluminum substrate to the constant current power drive board or circuit board. At present, all kinds of connections are completed manually: simple LED lights are connected from the power supply to the aluminum substrate light source with positive and negative wires. , more complex LED lights must also be connected between aluminum substrates. In order to achieve...

Problems solved by technology

[0004] The simplest and traditional method is to hold the electric soldering iron in one hand and the wire in the other, soldering point by point, and replenish the solder from time to time. Although many companies have developed soldering automation machines, they can only complete fixed-mode parts welding , for connections with various varieties and modes that cannot be fixed, it is impossible to automate the design

In view of this, people do not hesitate to waste aluminum substrates to design layouts that reduce connections, such as ring-shaped, gear-shaped, and snowflake-shaped light sources for ceiling lamps. In order to reduce connections, many scraps are discarded; the application number for my application is " 2013204039872", the utility model of "LED energy-saving lamp without welding wires in dark areas", although the connection is reduced by connecting the spring, but in actual operation, the production and placement of the spring is also very laborious
