HIGH FLUX LED ILLUMINATORS- 12 VOLT
EYE SAFETY ISSUES
Currently, the LED industry has no universally agreed upon standard to cover eye safety issues associated with the
use of LED products. The closest is CEI/IEC 60825-1, used in Europe, which was originally developed for lasers. It
was later amended to include LED’s, but some in the industry have reservations as to the applicability of this
standard to LED’s. Under this standard, the OTLH-0090-BU (470nm) and OTLH-0100-GN (530nm) are class 2 LED
products and carry the warning:
LED RADIATION
DO NOT STARE INTO BEAM (for 470nm and 530nm Sharks)
CLASS 2 LED PRODUCT
Handling and Other Precautions
These parts are high power devices and as such are intended to be used with a heatsink. Devices operated
without proper heat sink conditions, or proper current limiting will reach hazardous temperatures very quickly. Do not
operate devices under these conditions under any circumstances.
These parts contain a Beryllia ceramic substrate. Beryllia ceramic, in solid form and as contained in finished
products presents no special health risks. Warning: Overexposure to beryllium by inhalation may cause chronic
beryllium disease, a chronic lung disease, and cancer. Therefore; processing or recycling using (for example)
grinding, melting, welding, or sawing, of this device or as contained in a final assembly may produce airborne dust,
fumes, or mists and therefore the use of exhaust ventilation or other controls should be used to prevent exposure to
workers.
Electro-Static-Discharge
Any semiconductor circuit can be damaged by ESD. OPTO TECHNOLOGY INC. recommends that all LED circuits
be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause
damage to the component. ESD damage can range from subtle performance degradation to complete device
failure.
Silicone Overcoat
The Shark series components have a silicone overcoat, which is soft and flexible (40 durometer, Shore A) and
should not be immersed or cleaned with water, alcohol, or other chemical solvents or agents. The overcoat material
should not be removed, scraped, touched, pressed, or pulled to avoid stress damage and possible breakage of
delicate wire bonds.
Surface dust can be carefully removed with a soft brush, or canned air such as those used for cleaning
photographic lenses.
The silicone overcoat material has a flammability classification of 94 V-1 and a temperature rating of 130° C.
Mechanical Stress
This component is not suitable for SMT / solder reflow operations. Refrain from twisting leads or unconstrained
crimp or lead cut forces, which could break the glass seals of the leads and break internal wire bonds.
Life Support
OPTO TECHNOLOGY PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE
SUPPORT DEVICES OR SYSTEMS WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT OF
OPTO TECHNOLOGY INC. As used herein:
a. Life support devices or systems are devices or systems which (1) are intended for surgical implant into the body,
or (2) support or sustain life and whose failure to perform when properly used in accordance with instructions for
use provided in the labeling, can be reasonably expected to result in a significant injury to the user.
b. A critical component is any component of a life support device or system whose failure to perform can be
reasonably be expected to cause the failure of the life support device or system, or to affect its safety or
effectiveness.
The information provided herein is believed to be reliable, however OPTO TECHNOLOGY INC. assumes no
responsibility for inaccuracies or omissions.
OPTO TECHNOLOGY INC. reserves the right to make changes at any time without notice to any products to
improve reliability, function or design or to circuitry or specifications. OPTO TECHNOLOGY INC. does not assume
any liability arising out of the application or use of any product or circuit described herein, neither does it convey any
license under its patent rights, nor the rights of others.
