Abstract:
An integrally formed multi-layer light-emitting device is provided, which includes a seat, a plurality of light-emitting elements, and two lead frames. The seat is integrally formed in such a manner that the light-emitting elements can fit in the chamber which is formed on the top portion of the central main body. The seat is made of metal, and thereby the seat can effectively absorb heat from the light-emitting elements, and rapidly transmit it to the surrounding environment. Therefore, the packing module is not needed to be used in the present invention so that the consumption of the package material is reduced, and the manufacturing process is simplified.
Abstract:
An optical lens assembly having a fluorescent layer is disclosed, which includes a partition frame with a partition ring protruding inwardly from an inner wall surface of the partition frame, two optical lenses, and a fluorescent layer, wherein a slot space is defined by the two optical lenses and the partition ring of the partition frame, and the fluorescent layer is accommodated within the slot space. The top optical lens can be a flat slab lens, or a convex lens. When the optical lens assembly having a fluorescent layer is used in the optical device, the moisture can be prevented from entering the fluorescent layer, and thus the optical performance of the fluorescent layer can be maintained over a long period.

Abstract:
A method for packaging an airtight multi-layer array type LED is disclosed. The method includes: integrally forming a metal substrate with an airtight metal frame surrounding an accommodating space; forming a light outlet platform surrounding a light outlet opening on a bottom of the accommodating space; forming two sets of sealing through hole pairs in the airtight metal frame, wherein each set of the sealing through hole pairs has one lead frame inserted therethrough, and all interstitial space in the two sets of the sealing through hole pairs is completely sealed with a sealing material; disposing the optical units and optical components in the accommodating space; sequentially forming a dice protection layer, a fluorescent layer, and a silicone layer on the LED dices; and installing an optical glass cover on the top surface of the airtight metal frame to seal the packaging structure of the present invention.
Abstract:
An illuminating apparatus having a heat dissipation base and a multilayer array-type LED module is provided. The multilayer array-type LED module serves as a light source, and a heat dissipation element is provided. The multilayer array-type LED module is featured with a high luminescent efficiency and consumes less power, and the heat dissipation element is adapted for dissipating the heat generated by the multilayer array-type LED module by natural air convection. The combination of the multilayer array-type LED module and the heat dissipation element achieves a better performance of the illuminating apparatus, and can be conveniently further combined with other lamps, or even customized for satisfying different requirements and demands.
Abstract:
A thin multi-layer LED array engine is provided, which includes a substrate having a phosphor layer and a silica gel protection layer formed thereon. The phosphor layer is disposed on LED dices and makes direct contact with the substrate, and the silica gel protection layer is disposed on the phosphor layer. The LED dices are covered with the phosphor layer, and thereby the phosphor particles in the phosphor layer can be uniformly dispersed around the LED dices, so that the narrow color temperature distribution can be achieved. Furthermore, the phosphor layer makes direct contacts with the substrate, and thereby heat generated in the phosphor layer can be effectively dissipated through the substrate, and thereby the reliability of the optical components can be increased.
Abstract:
A method for manufacturing an integrally formed multi-layer light-emitting device is provided, in which a seat is integrally formed in such a manner that the light-emitting elements can be directly disposed in the chamber. The lens mask is used to seal the light-emitting elements in the chamber of the seat so that some packaging steps can be omitted, and the manufacturing process is simplified. The seat is made of metal having good thermal conductivity instead of plastic materials. The consumption of the package material is reduced, and the heat-dissipation efficiency is increased in the present invention.
Abstract:
An airtight multi-layer array type LED is disclosed, which comprises a metal substrate with an airtight metal frame formed thereon, and the metal substrate is integrally formed with the airtight metal frame, and an airtight sealing frame slot is formed around the upper surface of the airtight metal frame, the airtight metal frame is installed with two sets of sealing through hole pairs accommodating the lead frames. The interior of the airtight metal frame can be installed with packaging materials or optical components. The sealing holes are sealed with a glass or ceramic material. A fluorescent layer is formed on a silica gel layer, wherein the fluorescent layer can also be installed inside a silica glass package cover. The silica glass package cover is installed on the top surface of the airtight metal frame, and the silica glass package cover is engaged and sealed to a sealing rack. Nitrogen is filled in a space defined between the silica glass package cover and the fluorescent layer, so that moisture is prevented from permeating through the airtight metal frame and a dice protection layer. As such, a sealed-type LED packaging structure is formed and is suitable to be used in extreme or severe environments.
