REFLECTOR FOR A LED LIGHT SOURCE AND RELATED LED LIGHTING DEVICE

摘要

A reflector for a LED lighting device having an LED chip, including a second opening and a main optical surface, and a first coupling for fastening the reflector to the lighting device. The reflector includes a first portion having the first coupling and a second portion which is decouplable from the first portion. The main optical surface includes a first reflective optical surface and a second reflective optical surface realized respectively internally to the first portion and internally to the second portion. The reflector also includes a second coupling which connects and fastens stably in a non permanent manner the first portion to the second portion for make continuous the main optical surface and making the first portion and the second portion replaceable respectively with different first portions or different second portions by reducing the costs and number of moulds to make reflectors.

1. Reflector for a LED lighting device (10) provided with at least one LED chip (97), said reflector comprises a second opening (54) and a main optical surface (14) which is positionable around said at least one LED chip (97) so as to surround laterally the same for reflect and distribute in a homogeneous manner a luminous flux towards said second opening (54), further said reflector comprises first coupling means (40) which are realized in proximity of a first proximal end (31) for fasten said reflector internally to said lighting device (10), characterized in that said reflector comprises a first portion (30) provided with said first coupling means (40) and also comprises a second portion (50) which is decouplable from said first portion (30), and wherein said main optical surface (14) comprises a first reflective optical surface (35) and a second reflective optical surface (55) realized respectively internally to said first portion (30) and internally to said second portion (50), said reflector further comprises second coupling means (60) which connect and firmly fasten in a non permanent manner said first portion (30) to said second portion (50) for make continuous said main optical surface (14) and for make replaceable said first portion (30) independently from said second portion (50) and vice versa, and in particular for make said first portion (30) and said second portion (50) respectively replaceable with different first portions (30) or different second portions (50) by reducing advantageously the costs for the realization of moulds and especially the number of the moulds needed for realizing a plurality of reflectors for a plurality of different types of LED chips (97) each of which has in particular a plurality of different connector elements (20) or supports, or heat sinks for different types of LED lighting devices (10).
