Solid-state lighting devices and more particularly light-emitting devices for horticulture applications are disclosed. Light-emitting devices are disclosed with aggregate emissions that target chlorophyll absorption peaks while also providing certain broader spectrum emissions between the chlorophyll absorption peaks. The aggregate emissions may be provided by light-emitting diodes (LEDs) that emit wavelengths that correspond with certain chlorophyll absorption peaks and lumiphoric materials that provide broader spectrum emissions. The aggregate emissions are configured to have reduced emissions from lumiphoric materials in ranges close to certain chlorophyll absorption peaks, such as above 600 nanometers (nm). In this regard, light-emitting devices according to the present disclosure provide the ability to efficiently target specific chlorophyll absorption peaks for plant growth while also providing suitable lighting for occupants in a horticulture environment.

An ink jet process is used to deposit a material layer to a desired thickness. Layout data is converted to per-cell grayscale values, each representing ink volume to be locally delivered. The grayscale values are used to generate a halftone pattern to deliver variable ink volume (and thickness) to the substrate. The halftoning provides for a relatively continuous layer (e.g., without unintended gaps or holes) while providing for variable volume and, thus, contributes to variable ink/material buildup to achieve desired thickness. The ink is jetted as liquid or aerosol that suspends material used to form the material layer, for example, an organic material used to form an encapsulation layer for a flat panel device. The deposited layer is then cured or otherwise finished to complete the process.

A light-emitting diode (LED) includes a substrate, a semiconductor stacked structure disposed on the substrate, the semiconductor stacked structure including a first conductivity-type semiconductor layer, an active layer, and a second conductivity-type semiconductor layer, a wavelength converting layer configured to convert a wavelength of light emitted from the semiconductor stacked structure, the wavelength converting layer covering side surfaces of the substrate and the semiconductor stacked structure, and a distributed Bragg reflector (DBR) configured to reflect at least a portion of light wavelength-converted by the wavelength converting layer, in which at least a portion of the DBR is covered with a metal layer configured to reflect light transmitted through the DBR.
