5 / 13 page LUXEON CoB Datasheet DS115 20140328 ©2014 Philips Lumileds Lighting Company. 4 Table 2. Optical Characteristics Nominal CCT Typical Total Included Angle [1] (degrees) Typical Viewing Angle [1] u 0.90V 2u1/2 LHC1 - xxxx - xxxx 125 100 Notes for Table 2: 1. Total angle at which 90% of total luminous flux is captured. 2. Viewing angle is the off axis angle from lamp centerline where the luminous intensity is ½ of the peak value. Electrical Characteristics Table 3. Electrical Characteristics Nominal CCT Part Number Forward Voltage V, 85°C (V) Typical Temperature Coefficient of Forward Voltage [1] (mV/°C) DV F / DTJ Typical Thermal Resistance Junction to Case [2] (°C/W) Ru J-C Minimum Typical Maximum 2700K to 5700K LHC1-xxxx-1202 33 35.5 38 -16 0.67 2700K to 5700K LHC1-xxxx-1203 33 35.5 38 -16 0.49 2700K to 5700K LHC1-xxxx-1204 33 35.5 38 -16 0.40 2700K to 5700K LHC1-xxxx-1205 33 35.5 38 -16 0.32 2700K to 5700K LHC1-xxxx-1208 33 35.5 38 -16 0.22 Notes for Table 3: 1. Measured between T j = 25°C and Tj = 105°C at test current. 2. Junction temperature to back of PCB. Absolute Maximum Ratings Table 4. Operating Condition and Ratings Parameter Maximum Performance DC Forward Current 2x test current [2] ESD Sensitivity < 8000V Human Body Model (HBM) Class 3A JESD22-A114-E < 400V Machine Model (MM) Class B JESD22-A115-B Storage Temperature -40°C - 120°C LED Junction Temperature [1] 125°C Operating Case Temperature at Nominal Current -40°C - 105°C Reverse Voltage LUXEON CoB is not designed to be driven in reverse bias Notes for Table 4: 1. Proper current derating must be observed to maintain junction temperature below the maximum, please see preliminary application brief for additional information on thermal measurement guidelines. 2. Residual periodic variations due to power conversion from alternating current (AC) to direct current (DC), also called “ripple’, with frequencies ≥ 100 Hz and amplitude ±20% are acceptable, assuming the average current throughout each cycle does not exceed 2x test If. |
