NOVELTY - The illuminating or light-receiving device comprises a matrix array of rod lenses with a lens element (10)made of sealing glass (1) and a light-guiding element (20) made of sealing glass and/or made of holding glass (2), and active optical elements. The active optical element is enclosed by a sealing glass hermetically sealed in the rod lens, includes a member comprising a LED, a laser, a converter, a filter, a photo detector or a photovoltaic converter, and is provided in a space between the lens element and light guiding element and between two parts of light guiding element.    USE - Used as an illuminating or a light-receiving device.    ADVANTAGE - The illuminating or light-receiving device has less light conversion loss.    DETAILED DESCRIPTION - The illuminating or light-receiving device comprises a matrix array of rod lenses with a lens element (10)made of sealing glass (1) and a light-guiding element (20) made of sealing glass and/or made of holding glass (2), and active optical elements. The active optical element is enclosed by a sealing glass hermetically sealed in the rod lens, includes a member comprising a LED, a laser, a converter (6), a filter, a photo detector or a photovoltaic converter, is provided in a space between the lens element and light guiding element and between two part of light guiding element, and is located in a peripheral area of the light guiding element. The device further comprises a tubular, metallic casing member, which surrounds the sealing glass while leaving the lens element, and a metallic housing cap located in the space between the lens element and light guiding element. The housing cap supports and protects a further optically active element including a member comprising LED, an organic LED or a laser, a solar cell, charge-coupled device sensor, a complementary metal oxide sensor or a photo-receiver. A portion of the rod lens is non-reflective lens, or is coated with a cut-off filter. The matrix array comprises a common housing with a wafer for a hermetically sealed connection. The hermetically sealed connection includes the space with the LED, organic LED or laser, solar cell, charge-coupled device sensor, complementary metal oxide sensor or photo-receiver. The active optical element is mounted in an inclined surface of the light guiding element, and has rear side formed as a cooling surface. The rear side has a reflective coating. The space between the lens element and the light is filled with a polymer, a glass, a liquid and/or a composite. An INDEPENDENT CLAIM is included for a method for producing an illuminating or a light-receiving device.
