In February 2023, Nichia started a blog with the 1st post titled "Nichia's contribution to a realization of a mercury-free society" and for nearly a year, Nichia has been introducing examples of LED/LD replacement for mercury lamps in various fields. Maybe it was surprising to readers to find out that mercury lamps are still used in various applications in modern society. This includes fluorescent lamps, high-pressure sodium lamps (HPS) used in street lights and greenhouse lighting, low-pressure mercury lamps used in disinfection applications, high-pressure mercu...

Photolithography for the manufacture of semiconductors and printed circuit boards (PCBs) is another major application for mercury lamps classified under item 4(f) in the exemption list of the RoHS Directive. This is in addition to curing and photolithography for the manufacture of liquid crystal displays (LCDs), which were described in the previous posts. Photolithography is a lithography process in which a substrate coated with resist is exposed to light or an electron beam to draw a designed circuit. High-pressure mercury short arc lamps have been mainly used as the light ...

Heat and ultraviolet are used to cure paints such as coatings to protect the surface of car bodies, wooden floors, and plastic containers. Medium-pressure mercury lamps are the primary light source for ultraviolet curing (UV curing). Originally, heat and drying were mainly used to cure paints, but after the invention of the mercury lamp, the development of materials that can be cured with ultraviolet increased over time, and curing with ultraviolet became and remains widely used. Compared to curing with heat, UV curing can be used for heat-sensitive materials and can be done in a...

Until today since the discovery of ultraviolet germicidal effectiveness in 1901, primarily low-pressure mercury lamps have been used for disinfection with ultraviolet. Low-pressure mercury lamps contain mercury and therefore generate concerns regarding environmental pollution. LEDs are expected to be an environmentally friendly alternative technology, similar to the LED replacement of fluorescent lamps. However, although improving year over year at a great rate, the current efficiency of UV LEDs is still less than low-pressure mercury lamps. Thus, the RoHS Directive exe...

Today most fluorescent lamps are regulated by the RoHS Directive. However, despite containing mercury, there are still exemptions. In the field of general illumination, High Pressure Sodium lamps (hereinafter abbreviated as HPS) remain the highest runner of mercury-containing lamps. HPS is typically used in street lighting luminaires, classified under item 4(c) and for horticulture classified under item 4(f). They are exempt until at least February 24, 2027, due to the lack of alternative technologies. However, Nichia considers that the hurdles for alternative technolo...

As explained in the February 24, 2023 blog post, there remain lamps and light sources which contain mercury but are still exempt from the RoHS Directive. With its decades of experience and innovation, Nichia wants to contribute to the realization of a mercury-free society by promoting alternative light sources, specifically LEDs and Laser Diodes which do not contain mercury. The table below summarizes light sources which are exempt from the RoHS Directive and whose manufacture and sale are permitted even though they contain mercury. In fact, some items are classified mo...

As of today, 24 February 2023, most types of fluorescent lamps will be banned from manufacturing and sales in Europe. Despite containing mercury, these lamps have been allowed to be manufactured and sold as exemptions from the RoHS Directive. However, these exemptions end today and will no longer be extended. Lamps not covered this time will be subject to regulation in a phased manner, and general fluorescent lamps, except for some special applications, will disappear from the market in the near future. Under the Minamata Convention, which along with the RoHS Directive, i...
