LED cross-linkable phosphor coating
A light source ( 10 ) includes a light emitting component ( 32 ), such as a UV/blue light emitting diode or laser diode coated with a layer ( 60 ) of a phosphor material ( 64 ). The phosphor material converts a portion of the light emitted by the light emitting component to light of a longer wavelen...

| Summary: | A light source (
10
) includes a light emitting component (
32
), such as a UV/blue light emitting diode or laser diode coated with a layer (
60
) of a phosphor material (
64
). The phosphor material converts a portion of the light emitted by the light emitting component to light of a longer wavelength, such as yellow light. The thickness d of the layer varies across the light emitting component in relation to the intensity of light emitted by the light emitting component. This maintains a uniform color of the emission from the light source while minimizing the loss in light intensity (brightness) due to the presence of the phosphor. |
