Lighting device

A lighting device comprising:

• a light source comprising one or more light emitting devices, LEDs, and a diffusive, light emitting area, the light source being configured to transmit light through the light emitting area towards a light exit window of the lighting device, along an optical axis, the light emitting area having a periphery;
• and
• a transflective wall structure for reducing a glare of the light emitting area when viewed through the wall structure, the wall structure surrounding the light emitting area and extending between the light emitting area and the light exit window in a direction substantially parallel to the optical axis,
• wherein the light emitted from the light emitting area comprises a direct portion propagating directly between the light emitting area and the light exit window, and a divergent portion incident on an inwardly facing surface of the wall structure, and
• wherein the transflective wall structure is transparent and specularly reflective such that the divergent portion of the light is in part transmitted through the wall structure, and in part guided towards the light exit window by being specularly reflected by the wall structure,
• wherein the wall structure comprises first and second sidewall portions arranged on opposite sides of, and at a same distance from, the optical axis,
• wherein the light source is configured to emit the light in a luminous intensity distribution having at least a first plane of symmetry, and wherein th first and second sidewall portions are flat sidewall portions substantially parallel to the first plane of symmetry and arranged on opposite sides of, and at a same distance from, the first place of symmetry, and
• wherein the wall structure comprises third and fourth sidewall portions connecting the first and second sidewall portions and arranged on opposite sides of the optical axis.
