In ordinary diodes, this energy is radiated as heat while in an LED, energy is radiated as light. This effect is called
Electro luminescence.
Understanding Led Light Panels
LED Panel Lights consist of a flat surface with integrated light-emitting diodes (LEDs). These LEDs emit light
when an electric current passes through them, producing a bright and even illumination. LED panels are designed
to distribute light uniformly, eliminating shadows and glare, and providing a comfortable lighting environment.
Types Of Led Light Panels:
1 Edge-lit LED Panels
Edge-lit LED panels feature LEDs positioned around the edges of the panel, directing the light towards the center.
They utilize a light guide plate to distribute the light evenly across the panel’s surface. These panels are known
for their slim profile and are ideal for spaces with limited ceiling height.
2 Back-lit LED Panels
Back-lit LED panels have LEDs positioned at the back of the panel, facing the diffuser. The light is evenly distributed
across the panel through a diffuser, creating a uniform illumination. These panels offer excellent brightness and
are commonly used in commercial settings such as offices and retail spaces.
3 Direct-lit LED Panels
Direct-lit LED panels have individual LEDs distributed across the entire surface of the panel. These panels provide
a high level of brightness and are suitable for spaces that require intense illumination, such as warehouses and
industrial facilities. Direct-lit panels are also known for their robust construction and long lifespan.
4 Tunable White LED Panels
Tunable White LED panels allow you to adjust the color temperature of the light, ranging from warm white to cool
white. This feature enables you to create different lighting moods and adapt the ambiance of the space according
to your needs. Tunable White panels are commonly used in applications where dynamic lighting is desired, such
as art galleries and hospitality venues.
5 RGB LED Panels
RGB LED panels offer the ability to produce a wide range of colors by combining red, green, and blue LEDs.
These panels are often used for decorative purposes, allowing you to create vibrant and eye-catching lighting
displays. RGB panels are popular in entertainment venues, architectural lighting, and stage lighting applications.
6 Dimmable LED Panels
Dimmable LED panels provide the flexibility to adjust the brightness level according to the desired ambiance or
task requirements. These panels can be dimmed using compatible dimmer switches or control systems, allowing
you to create a cozy atmosphere or increase the light output when needed. Dimmable panels are commonly used
in residential spaces, restaurants, and hotels.
7 Emergency LED Panels
Emergency LED panels are designed to provide illumination in the event of a power outage. These panels
feature an integrated backup battery that automatically activates when the main power supply fails. Emergency
panels ensure a safe and well-lit environment during critical situations, making them suitable for areas where
uninterrupted lighting is essential, such as hospitals and emergency exits.
8 Customizable LED Panels
Customizable LED panels offer the flexibility to create unique lighting designs tailored to specific requirements.
These panels can be customized in terms of shape, size, color temperature, and even graphics or logos.
Customizable LED panels are often used in retail spaces, corporate offices, and architectural lighting installations.
Factors To Consider When Choosing Led Panel Lights:
When selecting LED panel lights, several factors should be taken into consideration:
Brightness and Output: Determine the required level of brightness and the desired light output for the intended
application.
Color Temperature: Choose the appropriate color temperature that suits the space and the desired lighting
ambiance.
Energy Efficiency: Look for panels with high energy efficiency ratings to reduce electricity consumption and
operating costs.
