Embodiment Construction

[0010] First, the metal base circuit substrate supporting an optical device of the present invention is explained in more detail.

[0011] The metal base substrate used in the circuit substrate of the present invention is made of aluminum or aluminum alloy. These materials are most suitable for use as circuit substrates for portable devices due to their excellent processability, low cost, and low weight. Furthermore, since aluminum has a high reflectivity for light ranging from ultraviolet to visible light, it can provide high external radiation even in the case of concave mirrors. Aluminum is therefore suitable not only for use in combination with lenticular LED modules, but also with reflective LED modules, which are characterized by a high luminous intensity. Aluminum also has a high reflectivity for light in the ultraviolet range of the spectrum. Therefore, the aluminum-based substrate is also suitable for use in combination with a lens type LED module using an ultraviol...

Abstract

A metal base circuit substrate for an optical device, which effectively reflects the generated light and radiates heat from the substrate, comprises a metal base substrate made from aluminum or aluminum alloy that supports an electric circuit via an insulation layer, wherein the insulation layer is formed from a transparent cross-linked silicone body, and the electric circuit is formed directly on the insulation layer. And an efficient method for manufacturing the aforementioned substrate comprises the steps of: a) applying a cross-linkable silicone onto the surface of a metal base substrate made from aluminum or aluminum alloy, b) cross-link

Description

technical field [0001] The present invention relates to a metal-based circuit substrate for an optical device, and a method of manufacturing the aforementioned substrate. More particularly, the present invention relates to a metal-based circuit substrate suitable for use in conjunction with an LED module or similar optical device, and efficiently reflecting generated light and radiating heat from the aforementioned substrate. The invention also relates to an efficient method for producing substrates having the aforementioned properties. Background technique [0002] The increasing integration, density, and operating frequency of electronic devices has stimulated the research and development of circuit substrates aimed at efficiently removing, by radiation, the heat generated during the operation of such devices. In order to radiate effectively, it is necessary to solve problems such as lowering the thermal resistance of the material making the circuit substrate, lowering th...
