Embodiment Construction

[0032] First, as shown in FIG. 1 and provided with a light-emitting diode arrangement with reference numeral 1, there is a light-emitting diode chip 2 which preferably emits blue light and is arranged side by side on a substrate 3, which has an insulating layer 4 and a The electrical conductive layer of the bulk path 5 is so as to make the electrical conductor path 5 contact the light emitting diode chip 2 through the wires leading from these electrical conductor paths to the upper side of the chip. It should be noted that the substrate 3 can also be constructed in other ways. In particular, specific measures can be adopted so that the light emitting diode chip 2 can effectively dissipate heat.

[0033] In order to convert the light emitted by the light-emitting diode chip 2 into a white light mixture, a color conversion material 7 is provided, which surrounds the light-emitting diode chip 2 and has color conversion particles, which are in particular phosphors, which convert at le...

Abstract

With a light-emitting diode arrangement (1) having a light-emitting diode chip (2) arranged on a base (3), and colour conversion material (7) surrounding the light-emitting diode chip (2), which material is constituted to convert at least a part of the light emitted by the light-emitting diode chip (2) into light of another wavelength, the colour conversion material (7) is surrounded to the side by a reflector (8), the lateral distance (x) of the light-emitting diode chip (2) to the reflector (8) amounting to at most 0.5 mm.

Description

Technical field [0001] The present invention relates to a light-emitting diode arrangement according to the preamble of claim 1, the arrangement having a light-emitting diode chip surrounded by a color conversion material, and the color conversion material is used to combine the light-emitting diode chip At least part of the emitted light is converted into light of other wavelengths. Background technique [0002] The field of light-emitting diodes, especially the so-called "white LED" field, forms the background of the present invention. Since semiconductor light-emitting elements generally emit light of a specific wavelength, products that directly provide white light semiconductor elements have not yet been realized. As an alternative, the semiconductor element is arranged so that it emits light of a single wavelength, for example, green, red or blue light. However, in order to be able to form white light, it is known from the prior art to convert the light of the blue LED into...
