IMAGE PROJECTION DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240184190 titled 'IMAGE PROJECTION DEVICE

The image projection apparatus described in the patent application includes a light source that emits blue light and a phosphor wheel that produces various colors of light by rotating the blue light. The phosphor wheel contains yellow phosphor for yellow light output and green phosphor, specifically (Lu1−xYx)3Al5O12, for green light output, enhancing light efficiency and color purity.

  • Light source emits blue light
  • Phosphor wheel rotates blue light to produce multiple colors
  • Phosphor wheel contains yellow phosphor for yellow light output
  • Phosphor wheel contains green phosphor, (Lu1−xYx)3Al5O12, for green light output
  • Improves light efficiency and color purity

Potential Applications: - Image projection systems - Entertainment lighting - Stage lighting - Digital signage

Problems Solved: - Enhanced light efficiency - Improved color purity in projected images

Benefits: - High-quality color output - Efficient light production - Enhanced visual experience for viewers

Commercial Applications: Title: Advanced Image Projection Technology for Enhanced Visual Displays This technology can be utilized in various commercial settings such as theaters, concert venues, advertising displays, and event productions to create vivid and dynamic visual experiences for audiences.

Prior Art: No information provided.

Frequently Updated Research: No information provided.

Questions about Image Projection Technology:

Question 1: How does the phosphor wheel enhance color purity in the projected images? Answer: The phosphor wheel contains specific phosphors that emit pure colors when excited by the blue light, resulting in improved color purity in the projected images.

Question 2: What are the potential cost implications of implementing this advanced image projection technology? Answer: The use of this technology may initially involve higher costs due to the advanced components required, but the long-term benefits of enhanced visual quality and efficiency may outweigh the initial investment.


Original Abstract Submitted

an image projection apparatus is disclosed. the image projection apparatus according to an embodiment of the present disclosure includes: a light source configured to output blue light; and a phosphor wheel configured to output a plurality of colors of light based on the blue light incident upon rotation, wherein the phosphor wheel includes: a substrate; a yellow phosphor disposed in a first region on the substrate for output of yellow light; and a green phosphor disposed in a second region on the substrate for output of green light, wherein the green phosphor includes (lu1−xyx)3al5o12, with 0<x<0.8. accordingly, highly efficient light output may be provided, and color purity may be improved.
