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. Las modalidades descritas se relacionan con un dispositivo de iluminación (1) que comprende una ventana de salida (2) y un substrato de fuente de luz (3) colocados para llevar al menos una fuente de luz en estado sólido (4), al menos una fuente de luz (4) se coloca para emitir luz a través de la ventana de salida (2) .P La ventana de salida (2) se forma para permitir una superficie frontal del substrato de fuente de luz (3) para que sea atraída en contacto físico con una superficie de la ventana de salida que da al substrato de fuente de luz (3), y en donde el substrato de fuente de luz (3) se mantiene en contacto físico con la ventana de salida (2), permitiendo así el contacto térmico entre el substrato de fuente de luz (3) y la ventana de salida (2). Debido a que el contacto térmico entre la ventana de salida y el substrato de fuente de luz se asegura, la transferencia de calor del dispositivo de iluminación mejorará.
