Abstract
Description
Die Erfindung bezieht sich auf ein Lichtsendeelement mit einem Halbleiter-Chip nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a light-emitting element with a semiconductor chip according to the preamble of claim 1.
Es
ist ein optisches zum Hinterleuchten von Flächen dienendes Senderbauelement
bekannt,
Die
Es ist Aufgabe der Erfindung ein Lichtsendeelement für die Ausleuchtung verhältnismäßig großer Flächen bspw. Displays zu schaffen, das sich bei baulich günstiger Beschaffenheit durch gute Funktion und einfache Herstellung auszeichnet.It The object of the invention is a light-transmitting element for the illumination relatively large areas eg. To create displays, the structurally favorable condition through good function and ease of production.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Patentanspruchs 1 gelöst. Weitere, die Erfindung ausgestaltende Merkmale sind in den Unteransprüchen enthalten.According to the invention this Problem solved by the features of claim 1. Further, the invention ausgestaltende features are included in the subclaims.
Die mit der Erfindung hauptsächlich erzielten Vorteile sind darin zu sehen, dass die Konstruktion des Lichtsendeelements, bestehend aus stoffschlüssig mit dem Träger verbundenem Halbleiter-Chip und letzteren gehäusefrei umgebenden Linse, vorzüglich geeignet ist vor allem relativ große Flächen bzw. Displays auszuleuchten. Dabei ist das Lichtsendeelement in der erfindungsgemäßen Ausprägung optisch effizient, und es zeichnet sich durch eine aufwandsarme Gestaltung aus, weil zu seiner Herstellung wenige Einzelteile erforderlich sind. Hinzu kommt, dass die Einhaltung von Toleranzen übersichtlich ist. Hervorzuheben ist auch noch, dass der Hallbeiter-Chip auf einem thermisch gut leitenden bspw. als Metallkernplatine dargestellten Träger angebracht ist. Die den Halbleiter-Chip umgebende Linse ist hochwirksam, weil allenfalls eine vernachlässigbare Lichtstreuung aufweisend, und sie ist mit einer geringen Bauhöhe versehen; dies gilt auch für dem Träger. Schließlich ist das Lichtsendeelementmodul, umfassend mehrere Lichtsendeelemente, problemlos herstellbar und mit räumlich vorteilhaften Abmessungen vielfältig einsetzbar.The with the invention mainly The advantages achieved are the fact that the construction of the Light-emitting element, consisting of materially connected to the carrier Semiconductor chip and the latter housing-free surrounding lens, excellently suitable is above all relatively large surfaces or illuminate displays. In this case, the light-emitting element is in the inventive expression optically efficient, and it is characterized by a low-effort design, because for its production a few items are required. in addition comes that compliance with tolerances is clear. highlight is also that the Hallbeiter chip on a thermally good conductive, for example, as a metal core board carrier shown attached is. The lens surrounding the semiconductor chip is highly effective because at most a negligible Having light scattering, and it is provided with a low height; This also applies to the carrier. Finally is the light emitting element module comprising a plurality of light transmitting elements, easy to produce and with spatial advantageous dimensions varied used.
in der Zeichnung wird ein Ausführungsbeispiel der Erfindung gezeigt, das nachstehend näher erläutert wird.in The drawing is an embodiment of the invention, which is explained in more detail below.
