Abstract
A modular LED lamp structure comprising a LED light source of the type mounted on a plate, a heat sink element having a flat face for supporting the LED light source and a central axis perpendicular to the flat face, a mask for locking the light source designed to press the light source itself, keeping it pressed against the flat supporting face of the sink element, means for removably fastening the metal mask to the sink element.
Claims6
A modular LED lamp structure comprising:
- an LED light source,
- a heat sink element having a flat supporting face for the LED light source and a central axis which is perpendicular to the flat face,
- means for conditioning the beam of light emitted by the light source,
- a mask for blocking the light source designed to press the light source by keeping it pressed against the flat supporting face of the sink element, the mask comprising an engaging area for the conditioning means,
- means for removably fastening the mask to the sink element, wherein the engaging area extends circumferentially inside the outer cylindrical portion to define, together with a suitably matched end portion of the conditioning means, a bayonet coupling designed to guarantee stable positioning of the conditioning means relative to the sink element, and wherein snap-on means for fastening the bayonet coupling.
A method for replacing a LED light source in a modular lamp structure comprising a LED light source, a heat sink element having a flat face for supporting the LED light source and a central axis perpendicular to the flat face, a mask for locking the light source designed to press the light source itself, keeping it pressed against the flat supporting face of the sink element, an interchangeable adapter element interposed between the light source and the mask for making the mask compatible with different light sources, and means for removably fastening the metal mask to the sink element, wherein it comprises the following steps:
- freeing the metal mask from the sink element by acting on the removable fastening means,
- removing the LED light source to be substituted and the respective interchangeable adapter element,
- positioning a new different LED light source on the sink element,
- positioning a new adapter element shaped to adapt to the new LED light source,
- positioning the metal mask on the adapter element and constraining it to the sink element by acting on the removable fastening means.
