Problems solved by technology

[0003] 1. The LED power supply will generate high temperature when it is powered on, and the heat-conducting potting compound itself has a large expansion coefficient. The high temperature generated inside will easily cause the heat-conducting potting compound to expand, and the expanded heat-conducting potting compound will easily cause damage to the joint of the power supply shell Extrusion will cause gaps in the joints, and eventually the waterproof performance will be damaged. At the same time, the stress generated by the heat-conducting potting compound during expansion may cause extrusion damage to the power supply components inside the power supply, resulting in LED power supply failure. damage to
The cost of potting thermal potting compound is also quite expensive
[0004] 2. The cost of thermal conductive potting glue is high, resulting in high production cost of LED power supply

Embodiment 1

[0025] Such as figure 1 As shown, this embodiment provides an LED power supply, including a power supply housing 2, an end cover 1, a power supply assembly 3 and a filler 4; the two ends of the power supply housing 2 are respectively covered with end covers 1, and The inside of 2 is provided with the above-mentioned power supply assembly 3 and filled with filling glue 4 .

[0026] Among them, the filler includes filler and thermally conductive potting glue; the filler accounts for 20% to 80% of the components. The filler can be any one or a combination of quartz sand, glass beads and ceramic sand. The thermally conductive potting compound can be any one or a combination of silica gel, polyurethane, and epoxy resin.

[0027] For the manufacture of the above-mentioned LED power supply, it is necessary to provide a potting process of filling glue, such as figure 2 and image 3 shown, with the following steps:

[0028] Step 101, use potting equipment to mix and stir the fill...

Abstract

The invention relates to the field of design and manufacturing techniques of LED power sources and particularly discloses an LED power source. The LED power source comprises a power source shell, end covers, a power source assembly and filling glue. The two ends of the power source shell are covered with the end covers respectively. The power source assembly is arranged inside the power source shell, and the power source shell is filled with the filling glue. By the adoption of the technical scheme, the power source shell can be filled with the filling glue with a low expansion coefficient, the combined portion of the power source shell is prevented from being squeezed, and the waterproof performance is maintained; meanwhile, the power source assembly is protected against squeeze damage, the service life is prolonged, the filling glue is equivalent to diluted heat conductive potting adhesive, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of LED power supply design and its manufacturing process, in particular to an LED power supply, filling glue and its potting process. Background technique [0002] In response to the national call for energy conservation and emission reduction, more energy-saving LED lighting products have gradually replaced the commonly used high-power, easy-to-wear general lighting products, and LED lighting products are widely used in different places and environments. LED lighting products mainly include LED lamps and their driving power. Among them, outdoor lighting is one of the main categories of LED lighting products. It is precisely because of the complexity of the outdoor environment that the waterproof and heat dissipation performance of the LED power supply is required to be high. In order to improve the waterproof and heat dissipation performance of LED lighting products, most existing manufacturers use the LED power sup...
