Cree XLamp XR-E LED Data Sheet

Transcription

1 Cree XLamp XR-E LED Data Sheet Cree XLamp LEDs combine the brightness of power LED chips with a rugged package capable of operating up to four watts. Cree XLamp LEDs lead the solidstate lighting industry in brightness while providing a reflow-solderable design that is optimized for ease of use and thermal management. Lighting applications featuring XLamp LEDs maximize light output and increase design flexibility, while minimizing environmental impact. Cree XLamp LEDs bring industry-leading brightness to a wide range of lighting and backlighting applications, including portable lighting and flashlights, outdoor and industrial, signaling, architectural, landscaping and entertainment/advertising installations.

4 Electrical Characteristics (T J = 25 C) 1 9 Forward Current (ma) Forward Voltage (V) White Thermal Design The maximum forward current is determined by the thermal resistance between the LED junction and ambient. Given an existing thermal resistance of 8 C/W between the junction and the solder point, it is crucial for the end product to be designed in a manner that minimizes the thermal resistance from the solder point to ambient in order to optimize lamp life and optical characteristics.

6 Reflow Soldering Characteristics The following reflow soldering profiles are provided for reference. Cree recommends that users follow the recommended solder paste profile provided by the manufacturer of the solder paste used.

7 Notes Lumen Maintenance Projections Based on internal long-term reliability testing and standardized forecasting methods, Cree projects XLamp LEDs to maintain an average of 7% lumen maintenance after 5, hours, provided the LED junction temperature is maintained at or below 8 C. Please read the XLamp Reliability application note for more details on Cree s lumen maintenance testing and forecasting. Please read the XLamp Thermal Management application note for details on how thermal design, ambient temperature, and drive current affect the LED junction temperature. Moisture Sensitivity If XLamp LEDs are exposed to excessively moist environments before soldering, damage to the LED may occur during the soldering operation. To avoid this damage, exposed lamps must be baked at 8 C for 24 hours. The following derating table (excerpted from JEDEC J-STD-33 Table Recommended Equivalent Total Floor Life) defines the maximum time (in days) under various humidity and temperature conditions that a lamp may be exposed before requiring baking. Maximum Percent Relative Humidity Temperature 3% 4% 5% 6% 7% 8% 9% 3ºC ºC ºC Within one hour of baking or one hour of opening the original packaging, XLamp LEDs must be stored according to Section 5.3 (Safe Storage) of JEDEC J-STD-33. Otherwise, these parts must be baked again at 8 C for 24 hours and resealed properly within one hour of baking. Do not bake parts at temperatures higher than 8 C, as damage to the reel will occur. RoHS Compliance The levels of environmentally sensitive, persistent biologically toxic (PBT), persistent organic pollutants (POP), or otherwise restricted materials in this product are below the maximum concentration values (also referred to as the threshold limits) permitted for such substances, or are used in an exempted application, in accordance with EU Directive 22/95/EC on the restriction of the use of certain hazardous substances in electrical and electronic equipment (RoHS), as amended through April 21, 26. Vision Advisory Claim Users should be cautioned not to stare at the light of this LED product. The bright light can damage the eye. Copyright All rights reserved.
