摘要：
A housing (10) for a lighting device is disclosed. The housing comprises anelongate base region (21) and opposing elongate sidewalls (23) extending from opposite elongate sides of the elongate base region towards respective terminal ends (24), wherein each of the opposing elongate sidewalls (23) has an optically transmissive inner surface (11) separated from an outer surface (13) by a distance of 5 millimeters or less to form a cavity (15) for housing a reflective foil or a thermally conductive member. The inner surface (11) extends across the elongate base region (21), and it comprises a recess (25) in the elongate base region (21) for housing a light engine (31). Also disclosed is a luminaire (1) including such a housing (10) and a method of manufacturing such an optically transmissive housing (10).
技术问题语段：
The technical problem addressed in the patent text is how to achieve a luminous output from SSL devices that matches that of traditional light sources, while also minimizing glare to the observer. The solution must consider the unique distribution of SSL elements, which is different from traditional light sources, and must also account for the high luminance that may be perceived when looking directly at SSL devices. Additionally, the solution must consider the need to reduce manufacturing costs and complexity, while still achieving the desired optical efficiency.
技术功效语段：
The invention is designed to make it easy to add extra parts to a lighting device's housing that support the operation of its SSL elements.
权利要求：
