PDS-002911 Rev 05 © 2019 Luminus Devices, Inc. - All Rights Reserved Understanding Luminus COB LED Test Specifications Every Luminus LED is fully tested to ensure it meets the high quality standards customers have come to expect from Luminus’ products . Technology Overview Luminus Chip-on-Board (COB) LED series offers a complete lighting class solution designed for high performance illumination applications . The Custom Color LED series has been specially design for retail shop lighting where enhanced red coloring is a preferred lighting standard . The selection covers a wide lumen range from less than 1,000lm to over 3,000lm . Intense color saturation characterizes these specialty LEDs . These breakthroughs allow illumination engineers and designers to develop beautifully lit spaces without sacrificing efficacy, brightness and overall quality . Reliability Designed from the ground up, the Luminus COB LED is one of the most reliable light sources in the world today . Having passed a rigorous suite of environmental and mechanical stress tests, including mechanical shock, vibration, temperature cycling and humidity . Only then are the devices qualified for use in a wide range of lighting application including some of the most demanding commercial applications . Delivered with fully qualified LM-80 test data and TM-21 lifetime results that certify lumen maintenance at 35,000 hours or more, Luminus COB LEDs are ready for the toughest challenges . UL Recognized Compliance Luminus COB arrays are tested in accordance with ANSI/UL 8750 to ensure safe operation for their intended applications . REACH & RoHS Compliance All LED products manufactured by Luminus are REACH and RoHS compliant and free of hazardous materials, including lead and mercury . Traceability Each Luminus COB LED is marked with a 2D bar code that contains a unique serial number . With this serial number, Luminus has the ability to provide customers with actual test data measurements for a specific LED . In addition, the 2D bar code is linked to manufacturing date codes that enables traceability of production processes and materials . Testing Temperature Luminus COB products are measured at temperatures typical for the LED operating in the fixture . Each device is tested at 85ºC junction temperature eliminating the need to scale datasheet specifications to real world situations . Chromaticity Bin Range Chromaticity binning delivers color consistency for every order . Standard products are delivered with a 3-step MacAdam ellipse . This ensures color performance matching in the application . For the most demanding application, Luminus is one of only a few companies that can provide a 2 SDCM .

Note 2: To prevent damage refer to operating conditions and derating curves for appropriate maximum operating conditions Note 3: Forward voltage is rated at typical forward current. For voltage at different forward currents, refer to the voltage versus current performance graphs. Note 4: COB LEDs are designed for operation to a minimum of 20% of the typical forward current value. Operation at currents lower than this value will not harm the device but may result in uneven light emission across the LES surface. Note 5: Luminus may change any specifications without prior notice. Please refer to the company web site for the latest datasheet revision Note 6: Caution must be taken not to stare at the light emitted from these LEDs. Under special circumstances, the high intensity could damage the eye.

(Part #) Product Datasheet PDS-002911 Rev 05 © 2019 Luminus Devices, Inc. - All Rights Reserved Handling Notes for Luminus COBs Luminus products are designed for robust performance in general lighting application . However, care must be taken when handling and assembling the LEDs into their fixtures . To avoid damaging Luminus COBs please follow these guidelines . The following is an overview of the application notes detailing some of the practices to follow when working with these devices . More detailed information is available on the Luminus web site at www .luminus .com . General Handling Devices are made to be lifted or carried with tweezers on two adjacent corners opposite the contact pads . At no time should the devices be handled by or should anything come in contact with the light emitting surface (LES) area . This area includes the yellow colored circular area and the ring surrounding it . There are electrical connections under the LES which if damaged will cause the device to fail . In addition, the ring frame itself should not be used for moving, lifting or carrying the device . Also do not attach any optics or mechanical holders to the ring as it is not capable to handle the mechanical stress . Static Electricity Luminus COBs are electronic devices which can be damaged by electrostatic discharge (ESD) . Please use appropriate measures to assure the devices do not experience ESD during their handling and or storage . ESD protection guidelines should be used at all times when working with Luminus COBs . Storage: Luminus products are delivered in ESD shielded bags and should be stored in these bags until used . Assembly: Individuals handling Luminus COBs during assembly should be trained in ESD protection practices . Assemblers should maintain constant conductive contact with a path to ground by means of a wrist strap, ankle straps, mat or other ESD protection system . Transporting: When transporting the devices from one assembly area to another, ESD shielded carts and carriers should be used . Electrical Contact Luminus COBs are designed with contact pads on their top surface . These pads are clearly marked with + and – polarity . Wires can be soldered to the contact pads for electrical connections or other solderless connector products are available . If wires are being soldered to the COB product, we recommend attaching these wires prior to mounting the devices to a heat sink . Please contact Luminus for specific recommendations on how to solder wires if not familiar with the standard practice . Luminus can also offer design recommendations for jigs to allow easily soldering multiple products in rapid succession . Chemical Compatibility The resin material used to form the LES can getter hydrocarbons from the surrounding environment . As a results, certain chemical compounds are not recommended for use with the Luminus products . Use of these compounds can cause damage to the light output of the device and may permanently damage the device . Please refer to www .luminus .com for a list of the compounds not recommended for use with the Luminus COB products . Thermal Interface Material (TIM) Proper thermal management is critical for successful operation of any LED system . Excess operating temperature can reduce the light output of the device . And excessive heating can cause permanent damage to the device . Proper TIM material is a crucial component for effective heat transfer away from the LED during normal operation . Please refer to www .luminus .com for specific recommendations for TIM solutions . Custom Color Series Product Datasheet
