Optical assembly for a spotlight, and spotlight comprising such an optical assembly

An optical assembly for a spotlight, comprising:

• an optical element equipped with a set of lenses, the lenses being adapted to cooperate with a first group of light sources for the spotlight, wherein the lenses are adapted to generate primary light beams and are spaced apart from one another using inter-lens spaces;
• a grille for filling at least part of the inter-lens spaces of the set of lenses, adapted to cooperate with a second group of light sources for the spotlight, wherein the grille is adapted to generate a secondary light effect;
• and
• a support element, adapted to support the set of lenses, in the inter-lens spaces, wherein the support element includes orifices located in the inter-lens spaces, the light sources in the second group of light sources are positioned to emit light through the orifices, and the orifices guide the light to exit the assembly via the grille in the inter-lens spaces and prevent light from leaking through the lenses;
• wherein the grille and support element are adapted to be superimposable by enclosing the optical element between an inner face of the grille and an upper face of the support element, and thereby fix the set of lenses in order to form the optical assembly.
