How can we negotiate with SMD LED customers without an order like this

How can we negotiate with SMD LED customers without an order? We also discussed the three key points of LED LED manufacturers.

I believe many people are familiar with the classification of LED light emitting diodes. Today, I will share some relevant knowledge with you.

Hello everyone, today we will talk about product quotes, viewing columns, selling boards, USB drives, beauty PC maintenance, etc. The following is a specific introduction about LED light emitting diodes.

Today, let's talk about the product name, purpose, characteristics, and purpose of SMD LED.

Hello everyone, this time we are talking about the SMDLED series of SMDLED products.

With the utilization of various industries, LED light emitting diodes are gradually replacing traditional commercial lighting and production lines, and they are still accompanied by the arrival of the global epidemic.

Hello everyone, today I will share with you the classification and related knowledge of SMD LED.

Hello everyone, today the editor and you are discussing the classification of LED light emitting diodes. 1、 The difference between low-power LED and high-power LED is that low-power LED are generally composite, high-power LED can meet the requirement of 1W, and even 10W are used outdoors.

Today we are talking about SMD LED. The main outstanding advantages of LED light emitting diodes.

SMD LED can operate continuously under different conditions. It is a solid-state semiconductor device that can directly convert electricity into light. Its heart is a semiconductor chip, one end of which is attached to a bracket, one end is a negative electrode, and the other end is connected to the positive electrode of the power supply, making the entire chip encapsulated in epoxy resin. A semiconductor chip consists of two parts, one is a P-type semiconductor in which holes dominate, and the other is an N-type semiconductor in which electrons dominate. But when these two semiconductors are connected, a P-N junction is formed between them. When an electric current passes through a wire and acts on this chip, electrons are pushed towards the P region, where they recombine with holes and emit energy in the form of photons. This is the principle of LED luminescence. The wavelength of light, also known as the color of light, is determined by the material that forms the P-N junction.

● Voltage: LED lamp beads use low-voltage power supply, and the power supply voltage is between 2-4V, which varies according to different products, so it is a high-voltage power supply;

● Protection: Before applying protection, waterproof measures must be taken to avoid eye looseness, and static electricity should also be taken to prevent damage to LED lamp beads.

● Luminous flux: When the light source is in use, the LED should also be waterproof to avoid eye looseness.

Uniform light color: The light source adopts imported chips, and each unit's LED light emitting diode tube is a spherical light source, so the unit is a display.

For lamp beads, the waterproof level and anti-static indicators must meet the standards, and of course, they can be tested through experiments.
