2-18 the time average luminous intensity may be adjusted for operating ambient temperature by the following exponential equation: i v (t a ) = i v (25 c)e [k (t C25 c)] color k algaas red C0.0095/ c her C0.0131/ c yellow C0.0112/ c green C0.0104/ c example: i v (80 c) = (25 mcd)e [-0.0112 (80-25)] = 14 mcd. mechanical these light bar devices may be operated in ambient temperatures above +60 c without derating when installed in a pc board configuration that provides a thermal resistance pin to ambient value less than 280 c/w/led. see figure 2 or 7 to determine the maximum allowed thermal resistance for the pc board, r q 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 60 c (140 f) 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. for further information on soldering leds please refer to application note 1027. a
