Description

A kind of LED bracket manufacturing process

Technical field:

The invention relates to the technical field of LED product manufacturing, in particular to a manufacturing process of an LED bracket.

Background technique:

As we all know, traditional incandescent lamps have high energy consumption, and the energy utilization rate is very low. Probably less than one-tenth of the energy is turned into light energy, and the rest is heat energy wasted in vain. So people have been looking for ways to replace incandescent lamps with new light sources. Therefore, energy-saving lamps came into being. Because it is cheaper and easier to make than incandescent lamps, it has been widely used and has a tendency to gradually replace incandescent lamps. Energy-saving lamps use the principle of electronic excitation to emit light. Compared with incandescent lamps, energy-saving lamps have the advantage of saving electricity. However, one disadvantage of energy-saving lamps is that energy-saving lamps contain mercury, and mercury plays an intermediary role in energy-saving lamps. Without mercury, energy-saving lamps will not emit light. This has resulted in mercury pollution in the production process of energy-saving lamps and after they are used and discarded. In addition, energy-saving lamps are still glass products, which are easily broken, difficult to transport, and difficult to install. Second, its power consumption is still relatively large. Finally, energy-saving lamps are easily damaged and have a short lifespan.

At present, the development direction of energy-saving lighting appliances is LED lamps. Compared with the above lighting fixtures, LED lamps have the following advantages:

1. Energy saving. The energy consumption of white LED lamps is only 1/10 of incandescent lamps and 1/4 of energy-saving lamps.

2. Long service life. The life of LED lamps can reach more than 100,000 hours, which is much higher than that of incandescent lamps and energy-saving lamps.

3. It can be started frequently. If the traditional energy-saving lamps and incandescent lamps are frequently turned on or off, the filaments will turn black and fail quickly, while LED lamps will not.

4. The solid-state package belongs to the type of cold light source, so it is very convenient to transport and install, and can be installed in any miniature and closed equipment. It is not afraid of vibration and basically does not need to consider heat dissipation.

5. Environmental protection, no mercury harmful substances. The assembly parts of the LED light can be easily disassembled and assembled, and the recycling is convenient.

Based on the above characteristics, LED lights will gradually replace other lighting fixtures.

There is a gap between the lead probe and the main body of the bracket so that they cannot be in contact, that is, the packaging pole table is in a suspended state relative to the main body of the bracket. In addition, due to the small size of the bracket, the precision of the mold is extremely high, and the It is necessary to consider problems such as mold injection runners, which greatly increases the cost of mold opening, increases the difficulty of the process, and makes it difficult to ensure the quality of the product.
