Problems solved by technology

However, this results in a very wide beam angle, which may be undesirable
It is also known to provide a metal reflector between the PCB and the tubular body for beam shaping, however, the cost of this reflector can be high and the complexity of the assembly of the lighting device increases, which results in a more expensive device overall

Embodiment Construction

[0037] It should be understood that the drawings are only schematic and not drawn to scale. It should also be understood that like reference numerals are used throughout the drawings to indicate like or similar parts.

[0038] Embodiments of the present invention relate to SSL component based lighting devices. Areas identified for improvement to provide SSL element based lighting are easy to construct. In particular, it would be desirable to provide more cost-effective SSL devices by providing easier to manufacture SSL element based lighting devices.

[0039] Referring first to Figure 1 of the drawings, it can be seen that a partially assembled lighting device 100 includes an elongated housing 110 (shown in cross-section perpendicular to the long axis) having a light exit window 112 . Within the housing 110 there is a carrier assembly 120 including a plurality of solid state lighting (SSL) elements 122 . There is also a reflector 130 between the housing 110 and the carrier ...

Abstract

The invention provides a lighting device (100) comprising an elongate housing (110) having a light exit window (112), a carrier assembly (120) within the housing comprising a plurality of SSL elements (122) and a reflector (130) between the housing and the carrier assembly. The reflector (130) has a plurality of apertures (132) therein. The apertures are between the housing and the carrier assembly. An adhesive (140) affixes the reflector to the housing and the adhesive extends through the apertures and affixes the carrier assembly to the housing. Such a lighting device may be assembled in a particularly cost-effective manner. There is also provided a method of assembling the lighting device and a luminaire comprising the lighting device.

Description

technical field [0001] The present invention relates to lighting devices, in particular lighting devices comprising solid state lighting (SSL) elements. [0002] The invention also relates to assembling a lighting device and to a luminaire comprising the lighting device. Background technique [0003] As the population continues to grow, it is becoming increasingly difficult to meet the world's energy needs while at the same time controlling carbon emissions to curb greenhouse gas emissions that are believed to be responsible for the phenomenon of global warming. These concerns have created a drive to use electricity more efficiently in an attempt to reduce energy consumption. [0004] One such area of ​​interest is lighting applications in domestic or commercial environments. There is a clear trend to replace traditional, relatively energy inefficient light bulbs, such as incandescent or fluorescent light bulbs, with more energy efficient alternatives. In fact, the produc...
