Problems solved by technology

The disadvantage of using louvers is that blocking light from reaching undesired areas comes at the expense of the performance of the luminaire, as the blocked light is not used and thus wasted
This can lead to a significant reduction in luminaire spacing, which in turn leads to an increase in the cost of the lighting installation

Embodiment Construction

[0026] will refer to Figure 1-3 A luminaire for road lighting according to a first embodiment of the present invention will be described. The luminaire 10 for road lighting comprises a bracket 11 on which a light source 12 is mounted within an enclosure 13 . Power is supplied to the light source 12 via electrical connections (not shown) on the bracket 11 . The light source 12 may be a high intensity discharge (HID) lamp, an LED type light source or any light source suitable for roadway lighting applications. The housing 13 is provided in its lower area with a light exit portion 15 comprising a light-transmitting medium made of a material having visible light transmission properties interposed between the light source 12 and the target area to be illuminated. The top side 132 of the housing 13 is provided on its inner surface with a reflective layer 14 to reflect light traveling from the light source 12 to the top side 132 of the housing 13 towards the light exit portion 15 ...

Abstract

Provided is a luminaire assembly (10; 20) comprising a support (11; 21) for receiving a light source (12; 22), a housing (13; 23) including a light exit portion (15; 25) disposed between a said light source (12; 22) and a target area to be illuminated and through which light from the said light source (12; 22) exits the housing (13; 23); a light intercepting element (161; 26) for preventing light from exiting the light exit portion (15; 25) along paths extending from the light exit portion (15; 25) in directions towards a region outside the target area. A luminaire including a luminaire assembly and a light source is also described.

Description

technical field [0001] The present invention relates to luminaire assemblies. In particular, but not exclusively, the invention relates to luminaire assemblies for roadway lighting applications. The invention also relates to a luminaire comprising such a lighting assembly. Background technique [0002] In lighting applications, such as roadway lighting applications, it is a growing problem that light emitted from a luminaire reaches areas outside the desired target lighting zone. This phenomenon is sometimes called light trespass. [0003] Various solutions for reducing light trespass from luminaires propose the use of louvers or shields to prevent light from the luminaire from reaching undesired areas. A disadvantage of using louvers is that blocking light from reaching undesired areas comes at the expense of the performance of the luminaire, since the blocked light is not used and thus wasted. This may lead to a significant reduction in the pitch of the luminaires, whi...
