The anode and cathode of each LED is brought out by separate pins. This universal pinout arrangement allows the LEDs to be connected in three possible configurations: parallel, series, or series parallel. The typical forward voltage values can be scaled from Figures 4 and 9. These values should be used to calculate the current limiting resistor value and typical power consumption. Expected maximum VF values for driver circuit design and maximum power dissipation, may be calculated using the following VFMAX models: AlGaAs Red HLCP-X100 series VF MAX = 1.8 V + IPeak (20 ) For: IPeak 20 mA VF MAX = 2.0 V + IPeak (10 ) For: 20 mA I Peak 45 mA HER (HLMP-2300/2600/2900), Yellow (HLMP-2400/2700/2900) and Green (HLMP-2500/2800/ 2900) series VF MAX = 1.6 + IPeak (50 ) For: 5 mA IPeak 20 mA VF MAX = 1.8 + IPeak (40 ) For: IPeak 20 mA The maximum power dissipation can be calculated for any pulsed or DC drive condition. For DC operation, the maximum power dissipation is the product of the maximum forward voltage and the maximum forward current. For pulsed operation, the maximum power dissipation is the product of the maximum forward voltage at the peak forward current times the maximum average forward current. Maximum allowable power dissipation for any given ambient temperature and thermal resistance (RJ-A) can be determined by using Figure 2 or 7. The solid line in Figure 2 or 7 (RJ-A of 600/538 C/W) represents a typical thermal resistance of a device socketed in a printed circuit board. The dashed lines represent achievable thermal resistances that can be obtained through improved thermal design. Once the maximum allowable power dissipation is determined, the maximum pulsed or DC forward current can be calculated. Optical Size of Light Emitting Area Surface Area Sq. Metres Sq.

The luminous sterance may be calculated using one of the two following formulas: Lv (cd/m2) = Iv (cd) A (m2) Lv (footlamberts) = Iv (cd) A (ft2) Refresh rates of 1 kHz or faster provide the most efficient operation resulting in the maximum possible time average luminous intensity. The time average luminous intensity may be calculated using the relative efficiency characteristic of Figure 3 or 8, IPEAK, and adjusted for operating ambient temperature. The time average luminous intensity at T A = 25C is calculated as follows: Iv TIME AVG = [ ] IAVG ITEST (IPEAK) (Iv Data Sheet) where: ITEST = 3 mA for AlGaAs Red (HLMP-X000 series) 20 mA for HER, Yellow and Green (HLMP-2XXX series) Example: For HLMP-2735 series IPEAK = 1.18 at IPEAK = 48 mA [ ] 12 mA Iv TIME AVG = 20 mA = 25 mcd (1.18) (35 mcd) 11 The time average luminous intensity may be adjusted for operating ambient temperature by the following exponential equation: Iv (TA) = IV (25C)e[K (TA Color -25C)] K AlGaAs Red -0.0095/C HER -0.0131/C Yellow -0.0112/C Green -0.0104/C Example: Iv (80C) = (25 mcd)e[-0.0112 (80-25)] = 14 mcd. Mechanical These light bar devices may be operated in ambient temperatures above +60C without derating when installed in a PC board configuration that provides a thermal resistance pin to ambient value less than 280C/W/LED. See Figure 2 or 7 to determine the maximum allowed thermal resistance for the PC board, R PC-A, which will permit nonderated operation in a given ambient temperature. To optimize device optical performance, specially developed plastics are used which restrict the solvents that may be used for cleaning. It is recommended that only mixtures of Freon (F113) and alcohol be used for vapor cleaning processes, with an immersion time in the vapors of less than two (2) minutes maximum. Some suggested vapor cleaning solvents are Freon TE, Genesolv DES, Arklone A or K. A 60C (140F) water cleaning process may also be used, which includes a neutralizer rinse (3% ammonia solution or equivalent), a surfactant rinse (1% detergent solution or equivalent), a hot water rinse and a thorough air dry. Room temperature cleaning may be accomplished with Freon T-E35 or T-P35, Ethanol, Isopropanol or water with a mild detergent.
