COB LED
CS40C-P1C28-CB000
REV:A/0
●Storage
1. Do not open the moisture proof bag before the devices are ready to use.
2. Before the package is opened, LED should be stored at temperatures less than 30℃ and
humidity less than 50%.
3. LED may be stored for 6 months. When the storage time has reached more than 6 months,
LED should be stored in a sealed container filled with Nitrogen gas.
4. After the package is opened, LED should be stored at temperatures less than 30℃ and
humidity less than 30%.
5. LED should be used within 168 hours (7 days) after the package is opened.
●Operating Procedure
1. COB 40W series products should be operated at 1.1A for ideal performance, but not more than
1.1A.
2. COB 40W series products are sensitive to static. Operators must wear static wristband
(wireless static wristband is prohibited) and be well grounded while working in the
environment with an ionizing air blower. Anti-static requirement should be under ESD
2000V.
3. Sufficient thermal management must be applied.Large LED forward current will cause high
junction temperature and reduce LED life.
4. Recommended Assembly Method is shown in Figure 1,COB 40W products must be used in
conjunction with heat-sinking devices and a thin layer of thermal grease should be applied
to the bottom surface of the LED source
