What is a high power LED chip

High-power LED chips refer to LED chips formed by packaging a single semiconductor epitaxial wafer with more than 1W.

For questions about LED chips, LED lamps and lighting products, please consult: Jinpurui Senior Engineer.

High-power LEDs are light-emitting diodes with a high rated operating current. The power of ordinary LEDs is generally 20mA, while high-power LEDs can reach 1W, 2W, or even tens of watts, and the working current can range from tens of milliamperes to hundreds of milliamps. Due to the current constraints of high-power LED in terms of luminous flux, conversion efficiency and cost, it is determined that the short-term application of high-power white LED is mainly lighting in some special fields, and the medium and long-term goal is general lighting.

Normally, the current of a single chip of high-power LEDs is 350mA

The power is 1W, but a single chip can also be pulled to 3W to use, at this time the current is 700mA, and the single passing current and power are too large, which will cause the chip to decay badly, so there is a polycrystalline COB integrated LED, according to the principle of series voltage division and parallel shunt.

1050ma/350ma=3

24V, 3 and 7 strings.

The power of LED chips, also depends on what kind of packaging, different manufacturers and different models of power are not the same, the working voltage is not the same, some are, some are, if it is **, it is basically yes, red, yellow, green, these three are, other colors are. The general LED with closed lighting, generally a single lamp bead is available, and there are large ones.

The LED chip is a sub-component of the LED lamp bead, which is an important part of it, and the one that emits light is the LED chip.

LED lamp beads, whether plug-in or patch, are composed of five parts: bracket, silver glue, chip, gold wire, epoxy resin glue, white LED and phosphor.

In terms of luminous colors, there are only three types of mainstream LED chips, namely R red, G green, and B blue, and white LEDs are made of blue chips and yellow phosphors.

An LED chip is a solid-state semiconductor device that can directly convert electricity into light. It is the heart of LED light beads.

The LED lamp bead is a light-emitting body composed of one end of the LED chip attached to a bracket, one end is the negative pole, and the other end is connected to the positive pole of the power supply, so that the whole wafer is encapsulated by epoxy resin.

The LED chip is the core of LED light, it is just a small square with 2 solder joints on the positive and negative electrodes. LED lamp beads are the positive and negative poles of the LED chip, which are connected to the bracket (that is, the foot of the LED lamp beads) through gold wires respectively to form a loop, and then use colloids to protect the fragile gold wires and chips as a whole.

There are too many differences between LED lamp beads.

First of all, the size of the specifications, such as straw hat direct plug-in lamp, SMD lamp beads (5050 3014 5730 2835 3528 3535), integrated lamp beads, COB flood light source and so on.

The difference between power, small power, medium power, and high power above 1W is 3528 20mA, 3014 30mA, 5730 150mA, imitation lumens high power 350mA, integrated, cob look at the series and parallel chips to calculate.

The difference in color temperature is about 3000K for warm light, about 4000K for neutral light, about 6000K for white light, and color temperature for colored light.

The difference between chips, the difference in packaging process, and so on.

LZ, hello, I don't know if you have seen the LED (if you haven't seen it, look at it), the LED chip refers to the thing that emits light in the LED, and the LED lamp bead refers to the LED light-emitting chip with the entire outside of epoxy resin (glue), I hope it will help you! lz can be referred to below. The composition of LEDs.

The LED lamp beads and LED chips you said are actually the same structure, but the packaging form is different, one is the traditional packaging, the other is the chip packaging, but its essence is the same.

Of course, it is different, the chip refers to the part of the LED lamp bead that emits light inside, and the LED lamp bead is of course the whole part composed of the bracket and the chip lens lamp.

LEDs, light-emitting diodes, are solid-state semiconductor devices that can directly convert electricity into light. The heart of an LED is a semiconductor wafer with one end attached to a bracket, one end is the negative electrode, and the other end is connected to the positive electrode of the power supply, so that the entire wafer is encapsulated by epoxy resin. A semiconductor wafer is made up of two parts, one is a p-type semiconductor, in which holes dominate, and the other end is an n-type semiconductor, which is mainly electrons here.

But when these two semiconductors are connected, a "p-n junction" is formed between them. When an electric current is applied to the wafer through the wire, the electrons will be pushed to the p-region, where the electrons will recombine with the holes, and then the energy will be emitted in the form of photons, which is the principle of LED luminescence. The wavelength of the light determines the color of the light and is determined by the material that forms the p-n junction.

The LED chip is the LED chip, which is relatively small and is the core component of the LED light-emitting diode.

In addition, it is said that the LED driver chip is an 8-bit or 16-bit channel LED constant current driver IC, which is an integrated IC. Such as TB62726, MBI5026, DM13C and so on.

LED chip: A solid-state semiconductor device.

The chip is the thing that emits light when it is energized, and it is processed in the bracket, and the LED light-emitting diode is produced by the chip emitting light, and they are generated according to the way that the PN junction is injected into the hole, and the chip is generally sapphire inch-bottomed.

It's just a glowing diode. Something that looks mysterious.

In layman's terms, LED is a light that emits light;

Professionally speaking, the LED chip is actually the PN section in the semiconductor, and the difference between it and the ordinary PN section is that it emits light when it is forward conducted.

The crystal is generated by the electricity of the sapphire.

A program module that manages the work of LEDs.

LED chips are the materials inside the lamp beads and are used to emit light.

The LED chip is a power chip used to drive the LED light.

In our company, chips are also called chips, which should refer to the same thing, but the names are different.

Chips can also be called chips, and generally Taiwanese-funded or larger manufacturers are called chips.
