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...

Examples

Embodiment 1

[0015] Example 1, such as figure 1 and figure 2 As shown, the driver board 1 in the LED ceiling lamp in which the driver board or the connection board pad and the aluminum substrate pad are butt-welded is made into a circle, and the diameter of the circle depends on the length of the aluminum substrate 4 and the size and size of the lamp panel. The area occupied by the driving electronic components. In Example 1, a 300mm disc with a 20W power LED ceiling lamp is used. The diameter of the driving board is 65mm. After the constant current driving electronic components are arranged, there is still about 6mm of space around the disc , Ten pairs of welding pads connected to the current output end are evenly arranged on the circular space, which are mirror images of the 4 butt welding pads of the aluminum substrate, and each group has two pads 2. Two pads are arranged side by side at the corresponding positions of the substrate, such as figure 1 , ten pieces of aluminum substrate...

Embodiment 2

[0017] Example 2, such as image 3 and Figure 4 As shown, the connection board (specially used as the circuit board for butt welding connection) in the LED energy-saving lamp with butt welding connection of the driver board or the connection board pad and the aluminum substrate pad is made into a strip shape, and the width of the strip is to accommodate two The occupied positions of the root jumper and the jumper pad and the butt welding pad are determined. In this embodiment 2, the total length of the strip is the product of the width of the aluminum substrate 4 and the number of aluminum substrates. The aluminum substrate consists of eight rectangles and can be formed In the shape of a regular octagonal prism, one side of the long strip is set to mirror the butt welding pads of the aluminum substrate, and the same number and shape of the pads are used as butt welding pads, and the other side is set to be connected in series and parallel between the butt welding pads Th...
