Advantages and disadvantages of LED lights LED features advantages: 1. Small size. LED is basically a small chip encapsulated in epoxy resin, so it is very small and very light. 2. Low power consumption. LED power consumption is very low. Generally speaking, the working voltage of LED is 2-3.6V. The working current is 0.02-0.03A. This means that it consumes no more than 0.1W of power. 3. Long service life. Under the proper current and voltage, the service life of the LED can reach 100,000 hours. 4. High brightness and low heat.

LED technology is advancing with each passing day, its luminous efficiency is making an amazing breakthrough, and the price is continuously decreasing. 5. Environmental protection. LEDs are made of non-toxic materials. Unlike mercury in fluorescent lamps, which can cause pollution, LEDs can also be recycled. 6. Rugged and durable. LEDs are completely encapsulated in epoxy resin, which is stronger than light bulbs and fluorescent tubes. There are also no loose parts inside the lamp body. These characteristics make the LED difficult to damage. Disadvantages: 1. It is expensive and requires constant current drive.

The heat dissipation is not easy and the light decays easily. 2. The lighting brightness is small, which is not suitable for large area lighting. 3, led lights will also generate heat and need to dissipate heat. 4. At the initial stage, LED lighting is mainly used in large-scale landscape lighting, not very suitable for high-use eye environment. At present, it is mainly based on experiments. 5, LED can not be simply used as an ordinary light source; its use requires driving power, optical and thermal conduction. 6, LED small lamp beads, after a few years of use will slowly wear out and cannot be replaced, easily causing the entire table lamp to be scrapped. LED is the abbreviation of light emitting diode in English. Its basic structure is a chip of electroluminescent semiconductor material, which is cured on the bracket with silver or white glue, and then the chip and the circuit board are connected with silver or gold wires. Then, the periphery is sealed with epoxy resin to protect the inner core wire. Finally, the outer shell is installed, so the shock resistance of the LED lamp is good.
