摘要： PROBLEM TO BE SOLVED: To provide a lens having a large light emergent angle, and a light source module including the lens.SOLUTION: The lens according to the present invention comprises: a light incident surface that is used for diffusing light emitted from a light source and squarely faces the light source; a light emergent surface that is positioned on a side face of the light incident surface; and a reflection surface that is disposed to face the light incident surface and is connected to the light emergent surface. A part of light transmitting the light incident surface is incident on the reflection surface, while the other part of the light transmitting the light incident surface is incident on the light emergent surface and directly emergent from the light emergent surface. Reflectance at the reflection surface is larger than transmittance through the reflection surface, and a part of light incident on the reflection surface is reflected at the reflection surface to be emergent from the light emergent surface and the other part of the light incident on the reflection surface transmits the reflection surface and is emitted externally outside the lens. Therefore, light passing through the lens can have a light emergent angle of 180° or more.

摘要： PROBLEM TO BE SOLVED: To provide a lens of which lighting range shows an approximately rectangular shape and which has a high light use efficiency, and a lighting device having the lens.SOLUTION: The lens includes a light emitting surface and a light incident surface. The light emitting surface has a first curved surface located at a central section of the light emitting surface, a first convex surface and a second convex surface respectively located on both sides of the first curved surface along a first direction, and a second curved surface and a third curved surface respectively located on both sides of the first curved surface along a second direction orthogonal to the first direction. The first curved surface diffuses emission light in the first direction, and condenses light in the second direction. Light-condensing capability in the first direction is smaller than that in the second direction on the first convex surface and the second convex surface. The second curved surface and the third curved surface diffuse emission light in the first direction, and condense light in the second direction. The lighting device uses the lens.

摘要： PROBLEM TO BE SOLVED: To provide a LED (light emitting diode) module whose distribution of emitted light satisfies actual illumination conditions. SOLUTION: The LED module has a LED having a central axis and a lens that covers the LED and includes a light incidence surface and a light exit surface. Descriptions will be given using an o-xyz three-dimension orthogonal coordinate system with the center of the LED being an origin o. An x-axis corresponds to the longitudinal direction of the lens, a y-axis corresponds to the width direction of the lens, and the central axis of the LED is located on a z-axis. The light exit surface of the lens has a central axis II in parallel to that of the LED. The central axis II is located on one side of a zox plane that is defined as a zx plane that includes the origin o. Accordingly, a light amount distributed on one side of the zox plane in the light that is emitted from the LED to be emitted from the lens is larger than that distributed on the other side of the zox plane.
