REMOTE PHOSPHOR LARGE-ANGLE SCATTERING PATCH LED
Document Type and Number:
WIPO Patent Application WO/2022/088293
Kind Code:
A1
Abstract:
A remote phosphor large-angle scattering patch LED, comprising: a thermally conductive electronic circuit board (1), a flip LED chip (2), and a plastic shell (7). A non-Lambertian dome structure cavity (5) is formed in the plastic shell (7); a mounting groove (6) is formed in the bottom of the plastic shell (7); the thermally conductive electronic circuit board (1) is mounted in the mounting groove (6); the flip LED chip (2) is mounted on the thermally conductive electronic circuit board (1) and located in the non-Lambertian dome structure cavity (5); and the two sides of the plastic shell (7) protrude out of the two sides of the thermally conductive electronic circuit board (1). The diameter of the plastic shell (7) is larger than the width of the thermally conductive electronic circuit board (1), such that downward light can be obtained, scattered light having a larger light-emitting angle can be obtained, safe light can be generated, and damage of blue light to human eyes can also be avoided. Soft light is not dazzling, glare or ghosting. Comfortable light is uniform and soft, and can create a warm and comfortable light environment.
