|20140247604||THIN LED LENS - Disclosed is a thin LED lens including a lens body being an inverted frusto-conical shaped structure, a light exit surface formed on a non-frustum end of the lens body, and an accommodating chamber formed at a frustum end of the lens body, characterized in that the accommodating chamber has a primary accommodating chamber and at least one secondary accommodating chamber disposed around the primary accommodating chamber, such that the primary accommodating chamber and the secondary accommodating chamber are arranged in a concentric and radial shape, and the secondary accommodating chamber is in form of a circular groove. The thin LED lens can be made thinner to achieve the effects of facilitating the manufacture, reducing the material, and providing a better light distribution.||09-04-2014|
|20140168998||LENS STRUCTURE OF A LIGHT EMITTING DIODE - A lens structure of a light emitting diode (LED) is provided, which includes a body. An outer surface of the body is formed by connection of an edge of a light input surface and an edge of a light output surface. A recess is formed convergently on the central part of the light input surface toward the light output surface. A divergent plane is formed on the end position of the recess. The divergent plane is a round surface with a radius of 0.05 mm to 1 mm. The divergence of the central light emitting from the LED is reinforced via the light output surface, and the amount of the central light emitting from the LED is limited by the area of the divergent plane. Accordingly, the difference of luminous intensity between the central part and the edge of the lighting area can be improved, thereby providing effects of uniform illumination.||06-19-2014|
|20140160768||OPTICAL LENS FOR FORMING SQUARE LIGHT PATTERN - An optical lens for forming a square light pattern includes a lens body, having a light-exit surface at the top of the lens body, an incident surface at the bottom of the lens body, and a containing space concavely formed at a center position of the incident surface for containing a light emitting source, and an edge line of the incident surface is enclosed into a geometric square pattern, and a corner of the geometric square pattern is designed in an arc shape, so that after a light emitted from the light emitting source passes through the lens body, the light is projected to a target projection surface to show a square light pattern, and the optical lens can be applied to a backlight module to provide a full-screen uniform light intensity of illuminated areas.||06-12-2014|
|20140133161||REFLECTIVE COVER MOLDING METHOD AND REFLECTIVE COVER MANUFACTURED THEREOF - A reflective cover molding method and a reflective cover manufactured thereof are disclosed. The reflective cover molding method comprises the steps of: providing a metal substrate; setting the metal substrate on a substrate mold, and punching the metal substrate by a pressure to form a circular substrate; propping the circular substrate onto a fixed mold with a prop; jointly rotating the fixed mold and the circular substrate, applying a pressure by a spinning roller to attach the circular substrate, and applying a pressure to spin out a molded cover; setting the molded cover onto a shaped mold, and punching the molded cover by a pressure to form an optical structure surface on the molded cover; and punching the molded cover to remove a bottom hole to form the reflective cover, so as to accelerate production rate and enhance product quality, stability and precision.||05-15-2014|
|20130250581||AMPLIFIED CONDENSING LED LIGHT LENS AND MODULE THEREOF - An amplified condensing LED light lens and a module thereof are disclosed. The lens is a downwardly tapered cup structure having a first light-incident surface and a second light-incident surface concavely disposed at the bottom of the amplified condensing LED light lens to form a containing space and a light-incident hole, and the containing space is provided for containing a light emitting source, and a residual light blocking structure is protruded from the first light-incident surface for blocking a residual light of the light emitting source. If the distance between the first light-incident surface and the light-incident hole is S, the distance between the bottom of the residual light blocking structure and the light-incident hole is L, 0||09-26-2013|
