Pipe-shaped LED lamp e.g. T5 LED lamp, for surface illumination in aquarium, has LED-lighting unit carrier and lens arranged in closed tube that is hermetically sealed by flaps, where lens is designed as cylindrical collecting lens

摘要

The lamp (1) has a LED-lighting unit carrier (3) and a lens (5) that are arranged in a closed tube (2), where the lens is designed as a cylindrical collecting lens. The tube is made from glass and hermetically sealed by flaps. A cooling body (4) is arranged at the lighting unit carrier within the tube. An adsorber material e.g. activated carbon or silica gel, for adsorption of gases and substances is formed in the tube. A getter is arranged in the tube for absorption of oxygen and/or organic substances, where the tube is filled with inert gas.
