Read below to discover why these are so important when choosing the right 24V LED strip light.

As the base material of LEDs, the LED bracket is an important material of LEDs and the carrier of the LED chip. The bracket is responsible for the heat dissipation and conduction, the thermal resistance of LEDs, and the initial defect rate. The main bracket materials in SMD LEDs are PPA, PCT, and EMC. Usually, the rated power is 0.2W LED using PPA, 0.5W LED generally using PCT, and more than 1W LED using EMC.

Usually, most of the LED strips sold on Amazon and eBay are made of PPA material, which has the worst heat dissipation performance, and the brightness and light efficiency are lower than those of PCT and EMC material LEDs. Due to the brittleness of EMC materials, EMC LEDs are rarely used in LED flexible strips. Therefore, PCT is the commonly used bracket material for high-end LED strips on the market, and it is also a material used by TILLUME high-end light strips. Since TILLUME chooses PCT+copper LEDs, the rated power of our LEDs can reach 0.5W. Of course, we will not let it actually work at 0.5W. In order to make it last longer, we generally reduce the power to use. For example, a person can lift a barbell with a maximum weight of 50KG, but if he keeps lifting 50KG, he is very prone to fatigue and injury, so the lifting time will be reduced. If we only let him lift 10KG objects, it will be much easier for him so he can lift for a long time.

There is a wire in the LEDs used to connect the electrical connection between the LED chip (also known as the chip) and the external pins. Once this wire fails, the entire LED will be scrapped, which shows the importance of this wire.

Commonly used wires are alloy wire and gold wire. Because of its good electrical conductivity, gold wire is a very good wire with a relatively small resistance value, Q=I*I*R, we can easily know from the heat formula that under the same current, the smaller the resistance value, The lower the calorific value. This can ensure that the LED has good performance, and it is not easy to blow the wire due to overheating.

Because the cost of gold is relatively high, the price of LEDs with gold wires is naturally relatively high. And some cheap LEDs generally use alloy materials as wires, which can greatly reduce the cost of LEDs and gain a price advantage. However, doing so will naturally reduce the service life of the LED or reduce the brightness of the LED lamp after a period of use.

Although the general consumers do not have special testing instruments to verify the material of the wire, TILLUME firmly does not use the LED of the alloy wire. A product should make people's lives better, then it must have a good quality to ensure long-term use. This is the most economical for the user.

LED Chips

Its main function is to convert electrical energy into light energy, and the main material of the chip is silicon. The semiconductor wafer consists of two parts, one part is a P-type semiconductor, in which holes dominate, and the other end is an N-type semiconductor, where electrons are mainly. But when the two semiconductors are connected, a P-N junction is formed between them. When the current acts on the wafer through the wire, the electrons will be pushed to the P region, where the electrons and holes recombine, and then emit energy in the form of photons, which is the principle of LED light emission. The wavelength of light, which is also the color of light, is determined by the material that forms the P-N junction.

The LED chip is the heart of the LEDs, which greatly affects the brightness and life of the LEDs. At present, the companies capable of producing LED chips on the market have very good technical strength, so there will not be too many problems with the reliability of quality. The problem is often due to the application problems caused by manufacturers adopting small-sized chips in order to save costs. It is the same as the case of wires. Larger-sized PN semiconductors perform better in terms of life and performance than small-sized semiconductors, but their cost will naturally be higher.

In practical applications, the specifications of LED chips selected by TILLUME are often larger than those of their peers, so as to ensure product quality. Therefore, the price of our products is higher than that of products sold on Amazon, eBay and other platforms. Although it will bring some difficulties to sales, TILLUME thinks it is worth doing compared to customer satisfaction.

There are not many parts of the light strip. Except for the LED, another important part is the FPC PCB. 

We can simply understand the PCB board as the wire used to connect each LED so that we can easily understand that the ability to carry current is an important parameter to evaluate the quality of the PCB board. With the same formula Q=I*I*R, a good PCB has good conductivity. The calorific value is low, and the pressure is reduced.

So what affects the conductivity of the PCB?

It is mainly reflected in the thickness of the PCB copper foil. The thickness of the copper foil is also high, the larger the cross-sectional area, the larger the current that can be passed, and the lower the heat. The thickness of PCB copper foil on the market is 18mil and 35mil. Of course, TILLUME LED light strip will choose 35mil copper foil as our PCB.

In addition, a roll of LED strips is at least 5M long, so many LEDs, the natural power will be relatively large, in order to better improve the ability of the PCB to pass current, we separate the main power supply line and the LED power supply line, and use two layers of copper foil To distribute the current that bears these 2 lines. Because of this design choice, TILLUME light strips have a very low voltage drop. Taking 5M as an example, our light strips have more than 50% less voltage drop than those on Amazon and eBay. In this way, the brightness of the light strip is kept as consistent as possible.

In addition to high-quality raw materials, we have also carefully designed our product solutions.

First of all, conventional LED strips are generally 60LEDs/meter, while TILLUME chooses 102LEDs/meter. From the number of LEDs alone, our performance is 40% higher, and this does not include the difference caused by the difference in LED materials. If we take into account that TILLUME chooses high quality LEDs, our performance is much higher than 40%.

In addition, the general design is 7.2W/M. Through calculation, we can know that the actual working power of each LED is 0.12W (7.2W/60=0.12W), while the actual working power of each LED of TILLUME 9W/M is (9W/102 =0.09W). From here we can easily see that TILLUME's design allows us to reduce the working pressure of LEDs by 33%, so that the life of the LED strip is naturally longer and more stable.

Since more LEDs are placed within 1M, the TILLUME light strip has a smaller LED spacing, and the light is more uniform when the LED strip is used.
