Applications of LEDs
Solid-state lighting (SSL) market is huge, being worth hundreds of billions of dollars.
In 2014, output value of SSL product in China was worth more than 350 billion RMB
[1]. SSL products consist of LED backlight, outdoor lighting, indoor lighting, LED
display, etc. This chapter focuses on key areas related to LED applications, including
an overview of technologies such as lighting, backlighting, display, communications,
and biological applications.
11.1 New Light Environment Technology
The primary role of SSL technology is energy saving. In contrast with conventional
artificial light sources, SSL has unique characteristics such as monochromaticity and
adjustability, which enables the expansion of its application horizon. This section
mainly introduces the main application fields of SSL, especially in general lighting
area where traditional lamps are being replaced. This could be ascribed to the fact
that LED has higher luminous efficiency, lower power consumption, longer lifetime.
Meanwhile, the device is safe, reliable and environment friendly. In recent years,
with the rapid development of industrial modernization and urbanization in China,
the relationship between supply and demand of energy and resources has become
increasingly tense, which puts new demands on China’s power supply and capacity.
Due to its outstanding features such as environmental protection and power saving,
LED is gradually replacing traditional light source, and more widely used.
