Embodiment Construction

[0027] The specific examples provided in the description given below should not be construed as limiting the scope and / or applicability of the appended claims. The lists and groups of examples provided in the description given below are not exhaustive unless expressly stated otherwise.

[0028] Figure 1a with Figure 1b A lighting system is illustrated according to an exemplary and non-limiting embodiment. Figure 1a An exploded view of the lighting system is shown. The lighting system includes: a base member 101; four light sources 102a, 102b, 102c and 102d; and an optical device 103 for changing the distribution of light emitted by the light sources 102a to 102d. The light source may be, for example, a light emitting diode (LED). In this exemplary case, the base element 101 is a circuit board comprising electrical conductors for supplying electrical power to the light sources 102a to 102d. The light source may be a surface mounted device (SMD), eg soldered to a connector...

Abstract

A lighting system comprises a substrate element (101), one or more light sources (102a-102d) mounted on a surface of the substrate element, and an optical device (103) for modifying light distribution. The lighting system further comprises one or more fastening elements (104) each being attached on the surface of the substrate element and comprising at least one spring arm(105)for elastically engaging the optical device to hold the optical device in place. The optical device comprises one or more apertures (106) and each fastening element is arranged to protrude through a corresponding aperture of the optical device,and the at least one spring arm of the fastening element is arranged to elastically engage edges of the corresponding aperture of the optical device..

Description

technical field [0001] The present disclosure generally relates to lighting engineering. More particularly, the present disclosure relates to an illumination system comprising: a base element; a light source mounted on the base element; and an optical device mounted on the base element and arranged to vary distribution of light. Background technique [0002] In some applications, the distribution of light produced by the light source may be important, even critical. The light source may comprise, for example, one or more light emitting diodes (LEDs), one or more incandescent lamps, or one or more gas discharge lamps. The distribution of light produced by the light source can be altered with optical elements such as lenses, reflectors, and combined lens-reflector elements (which include a portion acting as a lens and a portion acting as a reflector). In many cases, the lighting system comprises: a base element, eg a circuit board; a light source mounted on the base element...
