Phosphor Placement In White Light Emitting Diode Assemblies

View page
US Patent:
20130193465, Aug 1, 2013
Filed:
Jan 31, 2012
Appl. No.:
13/361965
Inventors:
Tao Xu - Fremont CA, US
Zhengqing Gan - Pleasant Hill CA, US
Assignee:
Bridgelux, Inc. - Livermore CA
International Classification:
H01L 33/50
US Classification:
257 98, 438 29, 257E33061
Abstract:
A white LED assembly includes a blue LED die attached to a substrate. A first volume of a first luminescent material surrounds the blue LED die in a lateral dimension such that none of the first luminescent material is disposed directly over the blue LED die. The first luminescent material includes a relatively inefficient phosphor having a peak emission wavelength longer than 620 nm and includes substantially no phosphor having a peak emission wavelength shorter than 620 nm. A second volume of a second luminescent material is disposed over the first volume and the blue LED die. The second luminescent material includes a relatively efficient phosphor having a peak emission wavelength shorter than 620 nm and includes substantially no phosphor having a peak emission wavelength longer than 620 nm. Placement of the first and second luminescent materials in this way promotes removal of heat from the inefficient phosphor and reduces the likelihood of interabsorption.

US Patent:
20220320051, Oct 6, 2022
Filed:
Apr 12, 2022
Appl. No.:
17/719361
Inventors:
- Livermore CA, US
Tao Tong - Pleasanton CA, US
Zhengqing Gan - Clayton CA, US
International Classification:
H01L 25/075
H01L 33/60
H01L 33/50
H01L 33/62
H01L 33/56
H01L 33/54
Abstract:
Light emitting assemblies comprise a plurality of Light Emitting Diode (LED) dies arranged and attached to common substrate to form an LED array having a desired optimum packing density. The LED dies are wired to one another and are attached to landing pads on the substrate for receiving power from an external electrical source via an interconnect device. The assembly comprises a lens structure, wherein each LED die comprises an optical lens disposed thereover that is configured to promote optimal light transmission. Each optical lens has a diameter that is between about 1.5 to 3 times the size of a respective LED die, and is shaped in the form of a hemisphere. Fillet segments are integral with and interposed between the adjacent optical lenses, and provide sufficient space between adjacent optical lenses so that the diameters of adjacent optical lenses do not intersect with one another.

Feb 19, 2019
Appl. No.:
16/279402
Inventors:
- Fremont CA, US
Vladimir ODNOBLYUDOV - Danville CA, US
Zhengqing GAN - Clayton CA, US
International Classification:
H01L 25/075
Abstract:
An LED CoB structure with the combination use of blue and red LED dies is used to achieve warm white light, with good quantum conversion efficiency at a reasonably low cost. Both the red and blue LED dies are fabricated on transparent substrates. The current density of the LED dies is designed to match the different degradation rate of each type of LED die. The methods used to achieve high efficiency include adjusting the power, wavelength, and/or position of the dies.
