LED light-emitting diode advantages and disadvantages

As a new type of semiconductor light source, the light-emitting diode has the following advantages compared with the conventional light source: long life, light-emitting time of up to 100,000 hours; short start-up time, response time of only several tens of nanoseconds; firm structure, as a solid whole The solid structure can withstand strong oscillation and impact; high luminous efficiency and low energy consumption is an energy-saving light source; the illuminant is close to the point source, and the radiation model of the light source is simple, which is beneficial to the design of the luminaire; the directionality of the illuminating is very strong, A reflector is needed to control the direction of illumination of the light, which can be made into a thin luminaire for applications where there is not much installation space. It is generally believed that the light-emitting diode is the fourth generation light source after incandescent lamps, fluorescent lamps, and high-pressure discharge lamps. With the advancement of new materials and manufacturing processes, the performance of LEDs is increasing and the range of applications is becoming wider and wider.
