No Page 1 3 / 15 1. Products and Application This specification defines general specification and performance for LM-U270A LED module. Samsung Linear Modules target to replace conventional fluorescent lamps as T5, T8 and so on with LED solutions. Due to transferring LED, new luminaire transferred to LED can take more energy saving and longer life-time. In special, Samsung has competitiveness in middle-power solutions. All of Linear modules use 2323(MP23L) that had been passed LM80. Middle power solutions provide more homogeneous and higher efficient lights. Linear module has been designed to expand length simply and adopt easy connection way. LM-U270A has paired module as LM-U039A for small room. When you design luminaire using LM-U270A, sometimes you can't cover your whole fixture. For that case, Samsung provides small LED module (LM-U039A). This specification describes only LED module but Samsung doesn't provide own driver. 2.

The color of white light can differ a little unusually to diffuser plate(sign-board panel). 2) Handling - Don't drop the unit and don't give the unit any shocks. - Don't storage the Module in a dusty place or room. - Don't take the unit to pieces. 3) Cleaning - This LED Module should not be used in any type of fluid such as oil, organic solvent, etc. - It is recommended that IPA(Isopropyl Alcohol) be used as a solvent for cleaning the LED Module. - When using other solvents, it should be confirmed beforehand whether the solvents will dissolve the package and the resin or not. Freon solvents should not be used to clean the LEDs because of worldwide regulations. Do not clean the LED Module by the ultrasonic. - Before cleaning, a pre-test should be done to confirm whether any damage to the LED Lighting will occur. 4) Static Electricity - Static electricity or surge voltage damages the LED Lighting. 5) Others - If over voltage which exceeds the absolute maximum rating is applied to LED Lighting, it will cause damage Circuits(that LED is included) and result in destruction. - Do not directly look into lighted LED with naked eyes for long time. - Please use this product within 5 months, which is kept in its original packaging unopened when stocked. Samsung-LED may make changes to specifications and product descriptions at any time, without notice. All rights reserved 2012 Samsung LED Co.,Ltd This is the last page.
