How long is the life of the in-line LED lamp beads? Will long working hours cause aging? Next, let’s take a look at it together; the life of LED lamp beads is generally more than 50,000 hours, and some people think that the life of LED lamp beads can operate for about 100,000 hours. LED is not simply no longer operating, its rated use The lifespan cannot be calculated by the measurement method of traditional lamps. In fact, when testing the life of an LED, no one will be sitting around waiting for it to stop functioning. However, there are other ways to measure the lifespan of an LED. The reason why LEDs last

It's because it doesn't have problems with blown filaments; the LED doesn't simply stop functioning, but it does gradually degrade over time. It is predicted that high-quality LEDs can maintain more than 60% of the initial lamp brightness after 50,000 hours of continuous operation. Assuming the LED has reached its rated service life, it may actually still be emitting light, but the light is very weak; to prolong the service life of the LED, it is necessary to reduce or completely dissipate the thermal energy generated by the LED chip, which is the stoppage of the LED. The main reason for the operation is that the life of the LED is related to the LED chip and the ELDerly driver, and then the drive power part, etc. are all related to the life of the "LED lamp. In addition, the quality also affects the life. Therefore, the common LED life value parameters in the LED lighting industry are Normal should be 30,000 to 50,000 hours.

      How it works: LED (Light Emitting Diode), a light-emitting diode, is a solid-state semiconductor device that can directly convert electricity into light. The heart of the LED is a semiconductor chip, one end of the chip is 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 chip is encapsulated by epoxy resin. The semiconductor wafer consists of three parts, one part is a P-type semiconductor, in which holes dominate, the other end is an N semiconductor, which is mainly electrons, and the middle is usually a quantum well of 1 to 5 periods. When the current acts on the wafer through the wire, the electrons and holes will be pushed into the quantum well, 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.

       A single LED lamp bead can only work at low voltage (about 3V) and low current (about a few milliamps), and the light emitted is very weak. Many LED lamp beads need to be connected in series or in parallel; at the same time, a single LED lamp bead is unidirectionally conductive. In order to make full use of the positive and negative half-cycle current of the alternating current, an integrated circuit chip is required to convert the alternating current 220V power supply into voltage and current energy. The direct current that matches the LED collection can meet the requirements of the LED lamp bead collection, so that it can emit light normally.
