Hi,
This is a request for scans of the Light Bars sections of printed catalogs from Kingbright, SunLED and possibly other LED manufacturers from 1980 or earlier through 2002; pre-1991 preferred. In Kingbright and SunLED .PDF catalogs from 2003 and later available online, Light Bars are usually combined with Bar Graph Arrays. In some issues Bar Graph Arrays & Light Bars are in their own catalog, sometimes they have their own chapter of a master catalog, and sometimes in master catalogs they're in subsections of Through-Hole Displays (numeric, alphanumeric & dot matrix). I hope this info makes it easier for anyone who has any of the catalogs I'm interested in to find the section I want to see.
Background:
I'm trying to discover the manufacturer and their part number of an old LED light bar that I believe was probably made by Kingbright or SunLED. The reason I think this is, a retail distributor who packaged the LED I'm interested in, Cal West Supply Inc., later replaced that LED with a similar but smaller one, Kingbright # L-835/2YDT (= SunLED # XEUY22D), without changing their retail package part number (CP-60). This later version part is a rectangular light bar with two dice spaced 6 mm center-to-center, 5 mm X 10 mm in frontal dimension. The original version's dice were 7 mm center-to-center, and it was 7 mm X 14 mm in frontal dimension. See attached image for photos and drawings. I believe that a manufacturer such as Kingbright would not change a part's size so significantly without changing their part number. To confirm or refute my hunch, I seek scans of old Kingbright and SunLED catalogs, to try to find the part number of the original, larger version. Kingbright was established in 1980 and SunLED was established in 1989. As of early 2005, the Cal West Supply/CAL-PAK LED catalog consisted of over 60 LED styles, of which two were SunLED parts and the remainder were Kingbright. Even the two styles Cal West claimed to have sourced from SunLED, had Kingbright equivalents. The part I'm looking for was first made some time before 1991, and was apparently discontinued some time before 2003. I'm hoping that knowing the part number and manufacturer, if they differ from the modern smaller version, might help me to locate more of these parts.
Other possible makers, IMO less likely to have made the part I'm interested in:
LEDtronics, Wintech, Lumex, Toshiba, Nichia, Stanley, Avago/Hewlett-Packard, Lite-On, Monsanto
Thanks in advance for your help!
