The prospect and development trend of LED lighting

The prospect and development trend of LED lighting Light-emitting diode (LED) is a rapidly developing technology that is being widely used in many general lighting fields. Typical applications of LED lighting are: indoor lighting (used in commercial, industrial and residential environments), outdoor lighting (street lights, parking lot lighting), and architectural and decorative lighting. In some cases, LED has become an effective solution for architectural lighting. Compared with other lighting technologies, LED has better performance, and thus has become the mainstream solution in the current general lighting market. Compared with other lighting technologies, LEDs have a longer service life. The working life of LED is as long as 1 hour, while the service life of incandescent lamp is only 1 hour, and the service life of small fluorescent lamp (CFL) is about 1 hour. Significant advantages in service life make LEDs very suitable for commercial and industrial applications that require large labor costs to replace lights. Energy efficiency is better than incandescent lamps and halogen lamps, and equal to fluorescent lamps. In addition, the efficiency of LEDs is constantly improving; the efficiency of white light LEDs (WLEDs) is expected to increase by about% in the following year. Small size. The external dimensions of LED lights are equivalent to MR and GU, while CFL cannot meet this type of application and has strong focusing characteristics. Unlike other lighting technologies, LEDs are very suitable for applications that require directional lighting, such as small-angle reflector lights. Higher efficiency at lower temperature. The working efficiency of fluorescent lamps decreases at low temperatures. In contrast, LEDs are very suitable for low-temperature working environments, such as refrigerator lights. The color of the light can be easily changed. This advantage makes RGB LED an ideal choice for architectural and scene lighting, which can change the light color in real time according to specific requirements. In short, LED has many advantages that incandescent lamps, halogen lamps and fluorescent lamps do not have. Based on these advantages, designers are constantly exploring more applications suitable for LED lighting.
