Basic parameters of 2835 warm white lamp bead
The2835-size LED lamp bead has the characteristics of low energy consumption, low heat generation, and strong controllability. It measures 2.8mm x 3.5mm. And "warm white light" means that the light emitted by the LED lamp bead has a relatively warm color temperature, usually between 2700K and 3500K. The light of this color temperature tends to be yellow, creating a relatively warm and comfortable atmosphere, and is often used for lighting needs in home lighting, restaurants, hotels and other places.
2835 technical parameters
Power: 0.1W Warm white product White light voltage: between 2.8-3.6V, warm white product band color temperature: 2700-3100k In addition, there are red light and yellow light voltage 1.8-2.3V. Current 30mA, white light flux 10-15LM.
Power: 0.2w white light/blue light/green light etc. Voltage: between 2.8-3.6V, red light and yellow light voltage 1.8-2.3V. Current 60mA, white light flux 20-25LM.
Power: 0.5w white light/blue light/green light etc. Voltage: between 2.8-3.6V, red light and yellow light voltage 1.8-2.3V. Current 150mA, white light flux 50-60LM
When choosing 2835 warm white lamp beads, you also need to consider the wire material, warranty time and other factors. The wire material usually includes gold wire, alloy wire, etc., and the warranty time indicates the warranty period of the lamp bead.

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?
