(7) Safety Guideline for Human Eyes
· In 1993, the International Electric Committee (IEC) issued a standard concerning laser product safety
(IEC 825-1). Since then, this standard has been applied for diffused light sources (BG-LEDs) as well
as lasers. In 1998 IEC 60825-1 Edition 1.1 evaluated the magnitude of the light source.
In 2001 IEC 60825-1 Amendment 2 converted the laser class into 7 classes for end products.
Components are excluded from this system. Products which contain visible BG-LEDs are now
classified as class 1. Products containing UV LEDs are class 1M. Products containing BG-LEDs can
be classified as class 2 in cases where viewing angles are narrow, optical manipulation intensifies the
light, and/or the energy emitted is high. For these systems it is recommended to avoid long term
exposure. It is also recommended to follow the IEC regulations regarding safety and labeling
of products.
(8) Others
· If the BG-LEDs are being used after being fixed into a case (container, box, etc...) the BG-LEDs must not
be mounted so that the epoxy lens is pressed or glued onto a plastic (or metal) board.
· Flashing lights have been known to cause discomfort in people; you can prevent this by taking
precautions during use. Also, people should be cautious when using equipment that has had BG-LEDs
incorporated into it.
· These BG-LEDs are designed and manufactured for standard applications of traffic signals.
It is recommended to consult with Nichia in advance if these BG-LEDs are used for other applications.
· User shall not reverse engineer by disassembling or analysis of the BG-LEDs without having prior written
consent from Nichia. When defective BG-LEDs are found, the User shall inform Nichia directly
before disassembling or analysis.
· The formal specifications must be exchanged and signed by both parties before large volume purchase begins.
· The appearance and specifications of the product may be modified for improvement without notice.
