LED lights have been developed for many years, its technology and market have stabilized. As the market space growth of LED lights has stabilized, and a lot of enterprises have joined the field in recent years, the market competition has become increasingly fierce.
According to the material classification of the PCB, the LED light strips are divided into the LED rigid strip and the LED flexible strip (LED tape light). Further subdivision, LED strips can be divided into high voltage LED strips and low voltage LED strips.
At present, there are two main applications for LED strip lights. The first one is indoor lighting, such as ceilings, TV backgrounds, cabinets, showcases, etc. Another one is outdoor lighting, such as the building, tree, advertising light box, etc.
Since the LED hard strips have good heat dissipation effect and long service life, they are widely used in places with high-quality requirements. LED tape lights are accepted by the average consumer in the market for their flexibility and convenience. Low-voltage LED strip lights are generally used in places with high safety requirements, such as public places and other places that people can easily reach. High-voltage LED strips are mainly used in the ceiling, air, and other places that people can't easily touch. Furthermore, since the low-voltage strip requires an additional transformer, its overall cost will be higher than that of the high-voltage light.
In fact, the applications of all these LED strips have no such very differences. In the vast majority of cases, they are universal. In order to seek breakthroughs and differentiation in this highly competitive market, more and more LED strip manufacturers are developing and producing professional LED strips for use in a specific field.

What cause dead LEDs on LED strip lights
Sometimes there will be dark areas in the light boxes. When you open the canvas, there are several LEDs on the LED light strips. After using for a while, there are several LEDs can't work, which is the phenomenon of dead LEDs that people in the industry say. So what are the reasons for the dead LEDs?
Firstly, the quality of the LED lights is the direct cause of the dead LEDs. The use of inferior lamp beads will greatly increase the chance of dead LEDs of LED light bars. LEDs are composed of various materials, such as brackets, chips, wires, glues, etc. If any of these materials are low quality may cause LEDs to die prematurely.
Secondly, a LED or line on the serial-parallel circuit board is disconnected, causing the other LEDs to be off. This situation will affect the normal operation of the whole segment of the led lights. The reason is that due to the low working voltage of the led lamp, it is generally necessary to use string and parallel connection to adapt to different working voltages. The more LED lamps in series, the greater the impact, as long as one of the LEDs or one of the lines in this LED strip is disconnected, which will cause the entire LED light fixture.
Moreover, the wiring error also will cause the LED lights to burn out. If the LED low voltage tape lights are directly connected to 220V AC power will damage the lights. If the power supply is correct but the lights are not working, it may be because the positive and negative poles being reversed.
The last reason is that the physical damage during packaging, transportation, and installation. In the packaging, transportation, and installation of the LED light strip, various physical damages occur, causing the dead LED.
