LIGHT-EMITTING DEVICE AND MANUFACTURING METHOD FOR LIGHT-EMITTING DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18513924 titled 'LIGHT-EMITTING DEVICE AND MANUFACTURING METHOD FOR LIGHT-EMITTING DEVICE
The light-emitting device described in the patent application consists of two light-emitting parts, each containing a light-emitting element and a light-transmissive member. These parts are separated by light-shielding members containing different additives for thermal conductivity.
- The device includes a first light-emitting part with a first light-emitting element and a first light-transmissive member, as well as a second light-emitting part with a second light-emitting element and a second light-transmissive member.
- A first light-shielding member is positioned between the first and second light-transmissive members, containing a first additive.
- A second light-shielding member is located between the first and second light-emitting elements, holding the two parts together and containing a second additive with higher thermal conductivity than the first additive.
Potential Applications: - This technology could be used in various lighting applications where thermal management is crucial. - It may find applications in automotive lighting, display technology, and general illumination.
Problems Solved: - Improved thermal conductivity between the light-emitting elements and transmissive members. - Enhanced heat dissipation capabilities for the overall device.
Benefits: - Better performance and longevity of the light-emitting device. - Increased efficiency in managing heat generated during operation.
Commercial Applications: Title: Enhanced Thermal Management Light-Emitting Device This technology could be valuable in the development of high-performance LED lighting products for commercial, industrial, and residential use. It could also be utilized in the automotive industry for advanced lighting systems.
Questions about the technology: 1. How does the use of different additives in the light-shielding members impact the thermal conductivity of the device? 2. What are the potential cost implications of implementing this technology in commercial products?
Original Abstract Submitted
The light-emitting device includes a first light-emitting part including a first light-emitting element and a first light-transmissive member disposed over the first light-emitting element, a second light-emitting part including a second light-emitting element and a second light-transmissive member disposed over the second light-emitting element, a first light-shielding member disposed between a first lateral surface of the first light-transmissive member and a second lateral surface of the second light-transmissive member and containing a first additive, and a second light-shielding member disposed between a first element lateral surface of the first light-emitting element and a second element lateral surface of the second light-emitting element, holding the first light-emitting part and the second light-emitting part, and containing a second additive having a higher thermal conductivity than the first additive.
