What is an LED panel light? How is it different from ordinary lamps?

1. What is an LED panel light?
LED Panel Light is an ultra-thin panel lighting device that uses LED as a light source, light guide technology and a uniform light-emitting structure.
Main structural components:
Aluminum alloy frame:
It plays a supporting and shell protection role, and has good heat dissipation performance, which can extend the life of LED lamp beads.
Light guide plate (LGP):
This is the core optical component of LED panel lights, which is used to convert the linear or point light generated by LED lamp beads into a uniform large-area surface light source.
Diffuser plate:
Put it above the light guide plate to make the light distribution softer and more uniform, reducing glare and dark areas.
LED lamp bead module:
Usually distributed on the edge or back of the lamp, using high-brightness, low-energy SMD (surface mount) LED.
Backplane:
Reflects and supports the internal structure to prevent light loss and help dissipate heat.
Driver:
Converts the mains power into the constant current/constant voltage power required by the LED to ensure that the lamp emits light stably and does not flicker.
Characteristics of the light-emitting method:
The whole is a surface light source, not a traditional point light source.
The light is evenly distributed without obvious shadows or dark areas.
It is commonly installed in embedded form, but can also be suspended or ceiling mounted, suitable for a variety of space styles.

2. What are the differences between LED panel lights and ordinary lamps?
The differences between LED panel lights and traditional lamps (such as fluorescent lamps, grille lamps, incandescent lamps) are reflected in many aspects:
Different light-emitting methods
LED panel lights use surface light source design, through the light guide plate and diffuser, the light is soft and evenly spread throughout the space, suitable for long-term use of the eyes.
Ordinary lamps such as fluorescent lamps or incandescent lamps use point or linear light sources, and the lighting may have obvious glare, shadows, local overbrightness or overdarkness.
Higher light efficiency and more brightness
LED panel lights can usually achieve a luminous efficiency of 100-140lm/W, and higher brightness at the same power.
Traditional lamps have low light efficiency, with an average of only about 15lm/W for incandescent lamps and between 60-80lm/W for fluorescent lamps.
Low energy consumption, more energy-saving
LED panel lights can save 50%~70% energy than traditional lamps, and long-term use can significantly reduce electricity bills.
For the same brightness lighting needs, LED only needs half or even less power to meet them.
Long life and low maintenance cost
LED panel lights usually have a lifespan of 30,000~50,000 hours, far exceeding incandescent lamps (1,000 hours) and fluorescent lamps (6,000~10,000 hours).
The frequency of lamp replacement is low, especially suitable for commercial or public spaces that are sensitive to maintenance costs.
More modern appearance and more flexible installation
LED panel lights are ultra-thin and lightweight, only a few centimeters thick, and can be easily embedded in the ceiling, suspended or surface mounted.
Ordinary lamps such as grille lights and downlights are large and old-fashioned in appearance, which are not suitable for the aesthetics of modern spaces.
Environmentally friendly, healthy and safer
LED panel lights do not contain harmful substances such as mercury and lead, and will not release toxic gases when broken, and meet RoHS environmental protection standards.
At the same time, there is no flicker, no ultraviolet rays, no electromagnetic interference, more eye protection, and suitable for long-term work or study environments.

3. What scenarios are LED panel lights suitable for?
LED panel lights are widely used in the following places:

4. Why are more and more people choosing LED panel lights?
Energy saving and environmental protection: save electricity costs and reduce carbon footprint
Comfortable and healthy: no glare, no flicker, protect eyesight
Worry-free and durable: one-time installation, long-term use, no need for frequent replacement
High-value design: ultra-thin, modern, suitable for various interior styles
Long-term money saving: although the initial cost is slightly higher, it saves more electricity and maintenance costs during the use period
