Line Lights

Linear lights are a type of lighting fixture designed in a linear form, with light sources arranged along a straight line, creating a continuous band of light. Compared to traditional point light sources, linear lights provide more uniform and softer light, reducing glare and shadows, thus improving visual comfort. Their linear layout is not only aesthetically pleasing but also flexibly adaptable to various spatial structures, making them an indispensable lighting choice in modern architectural lighting, commercial displays, and industrial environments.

Working Principle of Linear Lights

The optical design of linear lights is based on a continuous light source and an optical diffusion system. By arranging LED chips or fluorescent tubes in a neat line, a light guide plate or diffuser is used to evenly distribute the light, achieving a linear lighting effect without bright spots. The working principle mainly includes the following points:

• Uniform Light Distribution: The diffuser plate or frosted cover evenly refracts and scatters the light, resulting in smooth light output and avoiding the high-brightness spots and shadows produced by traditional point light sources.
• Linear Lighting Effect: The light source can extend to several meters or even tens of meters, achieving continuous illumination, which is very suitable for long spaces such as ceilings, cabinets, corridors, and display shelves.
• Electrical Control: Modern linear lights use dimmers, PWM modulation, or intelligent lighting systems to achieve precise control of brightness and color temperature, meeting the needs of different scenarios.
• Thermal Management Design: LED chips generate heat during operation. The heat-conducting base plate and heat dissipation design ensure stable light output and extend the service life.

Types of Linear Lights

Linear lights can be divided into the following categories based on the light source type, installation method, and functional characteristics:

LED Linear Lights

• Utilize closely arranged LED chips for high brightness and low power consumption.
• Can achieve multi-color light, dimming, and dynamic lighting effects, suitable for commercial, home, and office environments.

Fluorescent Linear Lights

• Use fluorescent tubes for soft and uniform light, suitable for long-term use in offices, factory workshops, or school classrooms.
• High brightness but relatively higher energy consumption compared to LEDs.

Dimmable Linear Lamps

• Support brightness adjustment and scene mode switching, allowing adjustment of light intensity according to usage needs.
• Commonly used in conference rooms, hotels, and home environments to create a comfortable lighting atmosphere.

Flexible LED Linear Lights

• The light strips can be freely bent and cut, adapting to curved surfaces, corners, or irregular spaces.
• Commonly used in architectural contour lighting, stage design, and creative installations, enabling a variety of dynamic lighting effects.

Recessed and Suspended Linear Lights

• Recessed into ceilings, walls, or cabinets, the light body is concealed, leaving only the light strip effect for a clean, modern design.
• Suspended linear lights are suitable for open commercial spaces, exhibition halls, or office lobbies.

Technical Characteristics of Linear Lights

The technical characteristics of linear lights determine their applicability and design flexibility:

• High Uniform Light Output: Reduces bright spots and shadows, protecting visual health.
• Adjustable Color Temperature: Modern LED linear lights can switch between warm white, neutral white, and cool white, meeting the needs of different work and living environments.
• Long Lifespan and Low Energy Consumption: LED light sources have a lifespan of over 50,000 hours and consume less power than fluorescent and traditional light sources.
• Flexible Installation: Flexible light strips can be bent and cut, supporting suspended, recessed, surface-mounted, and track installation methods.
• Smart Control: Remote dimming, timed switching, and scene mode switching improve ease of use.
• Low Glare and High Color Rendering: Using frosted covers or light guide plates, a high color rendering index (CRI>80) ensures accurate color reproduction.
• Diverse Applications: Widely applicable to home, commercial display, industrial, and scientific research scenarios.
• Safe and Reliable: Low voltage design, short-circuit protection, and waterproof and bend-resistant flexible light strips are suitable for long-term use.
