`
`Sehr geehrter Herr Menden.
`
`wir bedanken uns fOr lhr Interesse an unseren Produkten aus unserem Katalog
`1994/95 Seite 4 insbesondere des Produktes 'M.J-M-001-B, aber in weiB.
`
`Nach umtangreichen Versuchen Ober Prototypen hinaus zu ldeinen und mittJeren
`Serien haben wir eine ProzeBsicherheit Ober ein GaN Chip und eine Abdeckung aus
`Silikon und oder Epoxy vennischt aus Yttriumaluminat Ce (Y~012: Ce) gefunden,
`urn aus dem blauen Chip ein weiBieuchtendes Chip zu bekommen.
`
`Ob die Leuchtstarke momentan lhren Anforderungen entspricht entscheiden Sje bitte
`an Hand der 150 stock Muster, welche wir Ihnen aus laufender Produktion zur
`Vertagung stellen, bitte selbsl
`
`Als Anlage fQgen wir Ihnen unser vortaufiges Datenblatt in der Chip on Board
`Technologie mit der Umwandlung und Anwendung des vorgenannten Materials der
`Firma Osram bei.
`
`•
`
`DarOber hinaus, wenn Sie sich nicht zur Chip on Board Technologie entscheiden,
`kOnnen wir auch aus eigener Produktion unsere Leuchtdioden, wie auf Seite 27 des
`gleichen Kataloges in Weir! anbieten.
`
`Auch hier sind die umfangreichen Versuche der gleichen Verfahrensweise
`abgeschlossen.
`
`Entgegen der COB Technologie haben wir hier nur Leuchtdioden- Lead-Frames(cid:173)
`mit einem Reflektor gegossen und vomer Ober das blaue Chip in den Reflektor hinein
`das Konvertermaterial, wie bei COB Technologie, dosiert.
`Das Giel1material- Materialien der Firma Dexter Hysol - verwenden wir zur LED(cid:173)
`Produktion seit mehr als 5 Jahren erfolgreich.

`Your message of
`
`
`
`
`Dear Mr. Menden,
`
`We thank you for your interest in our products from our catalogue 1994/95 page 4, in
`particular the products WU-M-001-B, but in white.
`
`
`After extensive experiments beyond prototypes to small- and medium scale production
`we have found a process stability over a GaN-chip and a cover of silicone and
`or epoxy mixed of Yttriumaluminat: Ce (Y3Al5O12: Ce) for obtaining a white lighting
`chip out of the blue chip.
`
`
`Please decide on your own with the help of the 150 pieces of samples, which we
` provide to you out of our current production, whether the luminosity currently meets
`your requirements.
`
`We enclose our preliminary data sheet in the Chip on Board-technology with the
`conversion and application of above-mentioned materials of the company Osram.
`
`Further, if you should not decide for the Chip on Board-technology, we can offer
`you our LED out of our own production, as on page 27 of the same catalogue,
`in white.
`
`Here, the extensive experiments of the same process are completed, too.
`
`In contrast to the COB-technology, here we have cast only LEDs-Lead-Frames- with a
`reflector and before we dosed converter material, as in the COB-technology, over the blue
`chip into the reflector.
`The casting material – materials of the company Dexter Hysol – has been used successfully
`by us for producing of LEDs for more than 5 years.
