LIGHTING DEVICE WITH IMPROVED THERMAL PROPERTIES

摘要

The disclosed embodiments relate to a lighting device (1) comprising an exit window (2) and a light source substrate (3) arranged to carry at least one solid-state light source (4), the at least one light source (4) being arranged to emit light through the exit window (2). The exit window (2) is shaped to allow a front surface of the light source substrate (3) to be brought into physical contact with a surface of the exit window facing the light source substrate (3), and in that the light source substrate (3) is held in physical contact with the exit window (2), thereby enabling thermal contact between the light source substrate (3) and the exit window (2). Since thermal contact between the exit window and the light source substrate is secured, the heat transfer of the lighting device will be improved.

1. A lighting device, comprising
an exit window, and a light source substrate arranged to carry at least one solid-state light source, said at least one light source being arranged to emit light through said exit window, characterized in that said exit window is shaped to allow a front surface of said light source substrate to be brought into physical contact with a surface of said exit window facing said light source substrate, and in that said light source substrate is held in physical contact with said exit window, thereby enabling thermal contact between the light source substrate and said exit window, thereby facilitating the heat transfer from the solid state light source towards and through the exit window.
