Backlit LED panel lights can be classified based on various factors such as their shape, installation method, color temperature, and dimming capabilities. Here are some common classifications of backlit LED panel lights:

    Shape:

    a. Square: Backlit LED panel lights that have a square shape with equal sides.

    b. Rectangular: Backlit LED panel lights that have a rectangular shape with varying length and width dimensions.

    Installation Method:

    a. Recessed: Backlit LED panel lights that are designed to be installed into a ceiling grid or suspended ceiling.

    b. Surface-mounted: Backlit LED panel lights that are mounted directly onto the surface of the ceiling or wall.

    Color Temperature:

    a. Warm White: Backlit LED panel lights that emit a warm, yellowish light, typically with a color temperature between 2700K and 3500K.

    b. Neutral White: Backlit LED panel lights that emit a neutral, white light, typically with a color temperature between 3500K and 4500K.

    c. Cool White: Backlit LED panel lights that emit a cool, bluish-white light, typically with a color temperature between 4500K and 6500K.

    Dimming Capabilities:

    a. Non-dimmable: Backlit LED panel lights that cannot be adjusted for brightness. They have a fixed light output.

    b. Dimmable: Backlit LED panel lights that can be adjusted for brightness. They are compatible with dimming systems or controllers that allow users to vary the light output.

    Special Features:

    a. Tunable White: Backlit LED panel lights that offer adjustable color temperature, allowing users to customize the light from warm white to cool white based on preference or specific lighting requirements.

    b. RGB: Backlit LED panel lights that can emit a range of colors by using red, green, and blue LEDs. They can be programmed to produce dynamic color effects and are commonly used for decorative or accent lighting.

Besides,Backlit LED panel lights typically consist of several key components that work together to provide illumination. Here is a general overview of the structure of backlit LED panel lights:

    Frame: The frame of a backlit LED panel light is usually made of lightweight and durable materials such as aluminum or steel. It provides structural support and protection for the internal components.

    Light Guide Plate (LGP): The LGP is a transparent acrylic or polycarbonate panel that distributes and diffuses light evenly across the surface of the panel. It receives light from the LED light source and guides it uniformly across the entire panel.

    LED Light Source: The LED light source is a critical component that provides the illumination in a backlit LED panel light. It consists of a series of light-emitting diodes (LEDs) mounted on a circuit board. LEDs offer high energy efficiency, long lifespan, and various color temperature options.

    Reflective Sheet: A reflective sheet or layer is placed behind the LGP to enhance the distribution of light. It reflects light that passes through the LGP back towards the front of the panel, maximizing the overall light output.

    Diffuser: A diffuser panel is placed in front of the LGP to further scatter and soften the light, reducing glare and providing a more uniform illumination. The diffuser is typically made of materials such as acrylic or polycarbonate with a frosted or textured surface.

    Back Cover: The back cover encloses the back of the panel and protects the internal components. It is typically made of plastic or metal and provides a neat and finished appearance.

    Driver: The LED driver is an electronic device that regulates the electrical current and voltage supplied to the LED light source. It converts the incoming AC power to the appropriate DC voltage and current required by the LEDs, ensuring stable and reliable operation.

    Wiring and Connectors: Various wiring and connectors are used to connect the LED light source, driver, and other electrical components within the panel. These components allow for the proper electrical connection and control of the panel.

The specific design and arrangement of these components may vary among different models and manufacturers of backlit LED panel lights. Additionally, some panel lights may have additional features such as dimming capabilities, color temperature adjustment, or smart lighting controls integrated into their structure.
