Table lamp LED lamp beads list
School has started, and parents have begun to buy school supplies for their children, and they are becoming more and more attentive to protecting their children's eyes. People have begun to pay attention to healthy lighting. Healthy lighting refers to lighting appliances that protect people's eyes and are closer to natural light. With the development of science and technology, lighting design is efficient, low light attenuation, stable performance and energy saving. For example, the desk lamp is a commonly used lighting tool for children.
As a small-scale lighting appliance, the desk lamp is mainly used for study and work. As consumer demand increases, people have higher requirements for the appearance of the desk lamp, as well as for its spectral stroboscopic, illumination, brightness, and color temperature. , smart lights have put forward new requirements
Therefore, Hailongxing Optoelectronics has specially launched several lamp beads for table lamps, namely: 2835, 3030, 3528, 5050, 5730 and other LED lamp beads; these lamp beads are lead-free, comply with ROHS requirements, low power consumption, wide Viewing angle, high CRI, high luminous angle, meeting people's luminous brightness requirements for study and work.
1. Green and environmentally friendly: does not contain harmful elements such as mercury and xenon, which is conducive to recycling and does not produce electromagnetic interference;
2. High efficiency and energy saving: only consumes a few kilowatt hours of electricity for a thousand hours;
3. High safety factor: less current and voltage required, less heat generation, and no safety hazards;
4. Long life, high energy efficiency, fast startup;
5. Protect eyesight: DC drive, no flicker;
6. Small light decay, not easy to die; recommended models: 2835, 3030, 3528, 5050, 5730】】
The above lamp beads have a wide range of applications. In addition to table lamps, they can also be used in indoor lighting, auxiliary lighting, luminous characters, counter lighting, shopping mall lighting, fluorescent tubes and other fields.

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?
