The Development of Semiconductor LED Lighting Fixtures (2)

The future development trends of LED technology LEDs are compact, lightweight, operate at low driving voltages, offer full color, have long lifespans, high efficiency, are vibration-resistant, and are easy to control in terms of light output. These characteristics provide excellent conditions for designing lighting systems for various locations and purposes. People are accustomed to seeing things in sunlight, and for general lighting, the primary requirement is a light source that closely resembles the quality of sunlight. Therefore, white light LEDs are an important indicator of semiconductor lighting technology. Due to the low power and brightness of a single LED, they are not suitable for standalone use; thus, multiple LEDs must be assembled together to design practical LED lighting systems. However, currently, white light LEDs and...

The Development of Semiconductor LED Lighting Fixtures (1)

LED (Light Emitting Diode), also known as a light-emitting diode, is a type of solid-state semiconductor device that can directly convert electricity into light. The birth of the white LED in 1996 marked a further acceleration in the evolution of light. Looking back at the history of lamp development, there have been significant inventions approximately every 60 years since the advent of gas lamps in the 1810s. The incandescent lamp was invented in 1879, followed by the fluorescent lamp, which became common in 1938, and then the prototype of modern LED lighting, the white LED, was born in 1996. Reviewing the history of LEDs, deep red and yellow-green LEDs were developed in the 1960s.

What is the luminous flux of a fluorescent lamp?

It is well known that prolonged exposure to ultraviolet radiation can kill a large number of human cells. However, how many people are aware that ordinary energy-saving lamps and fluorescent lights emit invisible ultraviolet rays, and how many know the extent of the harm they can cause to the human body? American biochemist Anderson discovered that people who live or work under fluorescent lights for extended periods receive 50% more ultraviolet radiation than those who are not frequently exposed to fluorescent lighting, and their chances of developing skin cancer are significantly higher than those of the general population.
