How to use LED lamp beads to avoid undead lamps
With the rapid development of high technology, LED lamps have become the main product of the new generation lighting market with their technical characteristics such as high efficiency, energy saving, safety, longevity, compactness, and clear light. At the same time, they have also effectively promoted the rapid progress of the environmental protection and energy saving industry. However, during the LED production process, we often encounter the problem of dead LED lights. So how to prevent the LED lamp dead light problem? Below I will briefly outline the following points for you.
First of all, from a machine perspective, we should optimize the internal packaging process of LED lamp beads as much as possible to ensure the quality and stability of its internal components. By strengthening process control and reducing the occurrence of adverse phenomena, the life and reliability of LED lights can be effectively improved.
Secondly, the LED lamp dead light problem may be caused by long-term storage or aging. Therefore, we should regularly check and maintain the working status of LED lights, and replace seriously aged lamp beads in time to avoid failure caused by excessive use.
In addition, the problem of LED lights dying during the welding process may also occur. Therefore, we should pay attention to the selection of welding processes and welding materials to ensure reliable welding quality. At the same time, the time and temperature of the welding operation should be reasonably arranged to avoid damage and aging of the LED lamp beads.
Finally, in order to protect the appearance quality of LED lights, we should not use unknown chemical liquids to clean LED lights. Doing so may damage the appearance of the LED lamp beads and cause cracks. If cleaning is necessary, we should choose to do it in a room temperature and ventilated environment, and use appropriate cleaning agents to avoid damage to the LED lights.
To sum up, preventing the LED lamp dead light problem requires starting from many aspects, including optimizing the internal packaging process, timely replacement of aging lamp beads, paying attention to welding quality and avoiding improper cleaning. Only by comprehensively considering these factors can we effectively improve the reliability and lifespan of LED lights and promote the sustainable development of the LED lighting industry.
There are many welding methods for LED lamp beads on the chip, and the following is one of the commonly used methods for reference. First, use an electric soldering iron to heat some soldering tin on the positive and negative electrode pads of the lamp bead (the soldering tin must not be too much, otherwise, the positive and negative electrode pads will be connected once heated with a hot-air gun), then use a hot-air gun to heat the positive and negative electrode pads at the same time, after the tin melts, use tweezers to place the positive and negative electrodes of the lamp bead on the corresponding pad.
LED is the light emitting diode, which is a semiconductor solid light emitting device that converts electric energy into light energy. Its core is the PN junction. In addition to the forward conduction, reverse cut-off and breakdown characteristics of the general PN junction, it also has the light emitting characteristics under certain conditions. Its structure mainly includes the following parts: lead, bracket, encapsulation glue, bonding wire, LED chip, solid crystal glue and phosphor. The discoloration failure of LED lamp bead is closely related to its material, structure, packaging process and service conditions. The following will analyze the causes of its discoloration through specific cases.
LED lamp beads are also called light emitting diodes. It has a wide range of applications. Its luminous colors include red light, emerald green light, yellow green light, yellow light, purple light, blue light, white light and orange light. The above is monochromatic light. It can also be made into two or three colors.
The gold wire used to package LED lamp beads contains more than 99.99% gold. It is produced by drawing gold from this material. In addition to 99.99% gold, this gold also contains less than 1% other trace elements. One of the core components of LED lamp bead packaging is gold wire, which is the bridge connecting the luminous chip and the welding point, and plays a decisive role in the service life of LED lamp bead. So how to identify the purity of gold thread?
