  • Patent number: 11152545
    Abstract: Devices and techniques are disclosed herein which include a die including side surfaces such that light emitted from the die can exit through the side surfaces. The die includes a first surface and a second surface opposite the first surface such that the distance between the first surface and the second surface is at least 100 micro meters. The die also include a wavelength converting material deposited external to the die such that the wavelength converting material covers the side surfaces. The wavelength converting material includes phosphor particles, a transparent risen carrier, and transparent particles configured to increase the volume of the wavelength converting material, the transparent particles having a refractive index (RI) that is similar to the RI of the transparent risen carrier.

  • Patent number: 9437388
    Abstract: A system and method for depositing a phosphor composition onto a light emitting device improves manufacturing yield, simplifies conventional processes, and decreases costs. For example, a method of dispensing a phosphor composition onto a light emitting device includes dispensing a portion of the phosphor composition onto the light emitting device utilizing a plurality of colored phosphor dispensers each for dispensing a respective type of phosphor. Power is applied to the light emitting device to emit light, and a characteristic the light emitted by the light emitting device is detected. Phosphor mixing and phosphor dispensing are dynamically controlled. Therefore the color characteristics of phosphor dispensed on LEDs are consistent. The system and method may also reduce the difference between detected characteristic of the light and a desired characteristic of the light.

  • Patent number: 8013895
    Abstract: Optical motion sensing systems and methods are described. In one aspect, light from subfields of a scene is focused onto respective capture areas of a focal plane. Successive sets of contemporaneous local images are captured from the focused light. Respective saliency measures are derived from respective ones of the local images. Respective local motion measures are determined from comparisons of corresponding ones of the local images in ones of the contemporaneous local image sets. A respective global motion measure is produced for each of the contemporaneous local image sets based on the respective ones of the local motion measures and the respective ones of the saliency measures.
