US 2025/0169247 A1 · LED WITH SEGMENTED SEMICONDUCTOR STRUCTURE

Abstract

A compact LED package has a segmented semiconductor structure that may emit light and at least two wavelength converting structures absorbing the emitted light to emit their own light. One of the wavelength converting structures may emit infrared (IR) or near-infrared (NIR) light, e.g., for IR sensing functions, while the other may emit visible light. The wavelength converting structures may be ceramic platelets coupled to each other. The segments of the semiconductor structure may be individually addressable, and the segmented semiconductor structure may allow for a reduction of package size compared to conventional LED packages.

Dependent claims

A light emitting device, comprising:

a semiconductor structure comprising an active layer, the semiconductor structure comprising:
a first segment configured to emit light of a first wavelength;
a trench adjacent to the first segment;
and
a second segment spaced apart from the first segment by the trench and configured to emit light of the first wavelength;
a first wavelength converter arranged in the light path of the first segment and configured to absorb light of the first wavelength emitted by the first segment and emit light of a second wavelength different from the first wavelength;
and
a second wavelength converter arranged in the light path of the second segment and configured to absorb light of the first wavelength emitted by the second segment and emit light of a third wavelength different from the first and second wavelength.
