Looking for the strongest home appliance indicator beads in Guangzhou
Looking for the strongest home appliance indicator beads in Guangzhou? Hailongxing Optoelectronics will provide you with assistance. Our LED beads have unique characteristics of energy conservation and long lifespan.
2. LED beads are a green light source that does not contain ultraviolet and infrared light in its spectrum, and they have low heat and do not flicker. In addition, discarded LED beads can be recycled and do not contain harmful elements such as mercury, so using LED beads is very safe.
3. LED beads are driven by DC, with ultra-low power consumption, which can effectively convert electrical and optical power. Under the same lighting effect, they are more energy-efficient than traditional light sources.
4. Due to the use of solid cold light sources and encapsulation with epoxy resin for LED beads, there are no loose parts on the lamp body, and there will be no defects such as easy burning of the filament, heat accumulation, and fast light decay.
Basic parameters and power of indicator light beads
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?
