High-performance UVC LEDs allow manufacturers to migrate from mercury lamps
to solid-state lighting solutions.
Unlike mercury lamps
, which produce unflattering light with a blueish-green tint, GL-SP07 LED floodlights shine cool, white light.
With Mitsubishi's existing lineup of rear projection TVs, light from a mercury lamp
-- installed in the rear section -- is split up into red, blue and green to create images on the front screen.
To rectify the situation and foster the environmentally sound management of mercury lamp
wastes, the EcoWaste Coalition has put forward a number of recommendations, including the following:
The energy sources for UV or visible light cure are typically medium pressure mercury lamps
, pulsed xenon lamps, LEDs or lasers.
Since 2016, the government has also prohibited disposing scrap metal, mercury lamps
and batteries, waste oils and liquids and electronic product waste in landfills.
Current UV sterilizers use mercury lamps
which are bulky and require high voltage inputs, but this easy-to-install system is small, while still killing 99.9% of waterborne bacteria.
From silicone metal ingots which are processed before being used in the semi-conductor market, high quality quartz is finding increased application in high temperature lighting such as halogen and mercury lamps
and also metal halide lamps for car headlights.
Deep ultraviolet LEDs are a next-generation light source expected to replace mercury lamps
and have various applications including water disinfection in industry and air disinfection systems in healthcare.
The KESC had also fitted mercury lamps
with fancy glass covers to light the overhead circular railway bridge in the neighbourhood, and they were likely to be switched on by the next few weeks.
These are found in some oil-based stains and as an element in mercury lamps
and metal halide lamps which are high-discharge lamps.
