Classification of Linear Lights

LED linear lights can be classified into different types according to different classification standards. Here are some common classifications of LED linear lights:

  • Classification by LED Package
    LED linear lights are divided into SMD LED linear lights and COB LED linear lights.SMD LED linear lights use surface mount technology for LED package, which provides a more uniform and softer light. COB LED linear lights use chip package technology, which provides higher brightness and more concentrated light.
  • Classification by Control Method
    LED linear lights can also be classified according to the control method, such as constant-on and dimmable LED linear lights.Constant-on LED linear lights provide fixed light intensity and color temperature and can only be controlled by switches.Dimmable LED linear lights can be adjusted for brightness and color temperature to adapt to different occasions and needs.
  • Shape Classification
    The appearance of linear lights can be classified into straight, curved, circular, grid, etc.
  • Material Classification
    Linear lights can be made of different materials, such as metal, plastic, and wood.
  • Installation Method Classification
    Common installation methods for linear lights include embedded, ceiling-mounted, line slot, and suspension, which can be determined according to the type of space.

Applications of Linear Lights

Due to their unique linear design and a variety of color and brightness choices, linear lights can be applied to many different occasions and purposes.Here are the main applications of linear lights:

  • Application of Linear Lights in Home Scenarios
    Linear lights can be applied to various home spaces, such as the living room, bedroom, and kitchen, creating a stylish and comfortable lighting atmosphere.Linear lights can be installed on the ceiling above the dining table or suspended above the dining table to provide bright lighting for dining.They can also be installed on the kitchen ceiling or under the cabinets to provide bright lighting for cooking and cleaning.
  • Application of Linear Lights in Commercial Scenarios
    Linear lights can be applied to commercial places such as shopping malls, hotels, and restaurants, adding beauty and artistic sense to the space.Linear lights can be installed on the ceiling or walls of mall corridors or above mezzanines to provide bright lighting for customers.They can also be installed on the ceiling or above the tables in restaurants to provide bright lighting for dining.
