What is the principle of a light guide plate? 

Design Principles

The design inspiration for the light guide plate comes from the LCD display screen of laptops, which converts line light sources into surface light sources to provide a more uniform light distribution.  It adopts spectral analysis technology and laser engraving or digital printing technology, and is made in a constant temperature, humidity, and dust-free environment to ensure its high quality.

Principle of astigmatism

The light guide plate is made by pressing acrylic into smooth surface plates through injection molding.   Then use high reflectivity and non absorbing materials on the bottom of the board, and print circular or square diffusion points through screen printing to achieve the purpose of diffusing light.

What are the characteristics of light guide plates? 

High light conversion rate: More than 30% higher light conversion rate than traditional lamps, uniform light and long lifespan, indoor use can reach more than 8 years.

High efficiency: Under the same area of luminous brightness, the luminous efficiency is high and the power consumption is low.

Energy saving and environmental protection: Under the same brightness, using thinner products saves costs and meets the requirements of energy saving and environmental protection.

Simply put, the optical light guide plate of a ceiling lamp has distinct characteristics such as ultra-thin, ultra bright, uniform light guide, energy saving, environmental protection, no dark areas, durability, resistance to yellowing, and simple and fast installation and maintenance.
