  • Patent number: 9028111
    Abstract: A lens module for LED light sources including: a lens body; and an LED light source received in a recess of the lens body. By the conditions of Z1>Z2 and Z3>Y1, and with the shape of light incident surface and the position of LED light source, a light deflection effect is achieved. This allows light emitted from the LED light source to be refracted by the light incident surface and then emitted by the light exiting surface, generating an excellent light deflection effect, thereby increasing illumination in width at the road or public squares and increasing utilization rate of the LED light source.

  • Patent number: 8025429
    Abstract: An LED illumination lens can guide light from light emitting diodes (LEDs). The incident surface and transmission surface of the lens are a part of an elliptical shape. The present invention makes an optical lens which provides that light is refracted twice by the LED illumination lens, and the output light is more uniform and present a long elliptical output light. The curve surface of the transmission surface is selected from elliptical surfaces, rectangular surfaces, square shape surfaces, round surfaces and rectangular surfaces with a cut corner, and polygonal surfaces. An LED illumination lens serves to refract the light beam from the LED by the incident surface and then disperse by the transmission surface 12 into a slender and long elliptical light beam.

  • Patent number: 8007139
    Abstract: The present invention relates to an optical illumination module that includes a fixed light source and a plano-convex lens. The fixed light source is a light emitting diode. The plano-convex lens is an aspheric lens with rotational symmetry, and disposed to a specific distance of an optical axis of the fixed light source. The specific distance is greater than or equal to 13.5 millimeter, and is smaller than or equal to 17.5 millimeter. The plane of the plano-convex lens is a light-beam incident plane, and a convex end is a light-beam exit plane. When the fixed light source is disposed at a coordinate origin, the convex curve of the plano-convex lens is composed of a series of points having specific coordinates. When the plano-convex lens shifts within the specific distance, a parallel light beam form the fixed light source can be refracted to achieve an effect of enhancing the uniformity of luminous brightness.

  • Patent number: 8000034
    Abstract: This invention is regarding to an innovatively designed lens that employs two holes of different shapes as light-inlet and light-outlet surfaces to direct lights. The main feature is that the light can emit out at a more focused and uniformed fashion through refraction and total reflection. On the other hands, the lens also has grooves set to allow for side lighting purposes when needed. And with the grooves, the light can emit at a wide range when multiple such lens are properly assembled.

  • Patent number: 7976201
    Abstract: A two-side illuminating lens body mainly projecting light from a light emitting device to two relative outer directions includes a base with a receiving slot having a downwards opening for receiving a lighting device. A concave arc for receiving the light emitting portion of the lighting device is formed above the receiving slot as a light incident side. On a top surface of the base, two symmetrical non-spherical protrusions are jointly arranged beside a center light axis. A concave curved surface is formed to a border of the two non-spherical protrusions. Two symmetrical awl laterals are formed on relative outer edges of the non-spherical protrusions. Through three different refracting types of the concave curved surface, non-spherical protrusions, and awl laterals, rays from the light emitting device will be gradually diffused away from the center light axis so that a double-side skew light distribution of illumination like a butterfly is projected.
