Abstract
A lighting device, comprising a solid state light emitter and a removable encapsulant element. A lighting device element, comprising a solid state light emitter and an encapsulant holding element configured to releasably hold a removable encapsulant element. A lighting device component, comprising a removable encapsulant element. A method, comprising removing a first removable encapsulant element from a lighting device that comprises at least a first solid state light emitter and inserting a second removable encapsulant element into the lighting device. An encapsulant element comprising a substantially transparent first material and a luminescent material within the first material.
Claims65
A lighting device, comprising:
- at least a first solid state light emitter;
- and
- at least a first removable encapsulant element, the first removable encapsulant element non-liquid, the first removable encapsulant element is the first element that light emitted from the first solid state light emitter enters after said light is emitted from the first solid state light emitter, an interface between the first solid state light emitter and the first removable encapsulant element is substantially or completely without a gap.
A lighting device element, comprising:
- at least a first solid state light emitter;
- and
- at least one encapsulant holding element configured to releasably hold at least a first removable non-liquid encapsulant element where at least some light emitted by the first solid state light emitter would enter the first removable encapsulant element, and the first removable encapsulant element would be the first element that said light enters after said light is emitted from the first solid state light emitter, and an interface between the first solid state light emitter and the first removable encapsulant element would be substantially or completely without a gap.
A lighting device component, comprising a removable encapsulant element, the removable encapsulant element configured to be the first element that light emitted from a first solid state light emitter enters after said light is emitted from the first solid state light emitter, the removable encapsulant element configured to be positioned such that an interface between the first solid state light emitter and the removable encapsulant element is substantially or completely without a gap the removable encapsulant element non-liquid.
A method, comprising:
- opening a first encapsulant holding element that retains a first removable encapsulant element, the first removable encapsulant element non-liquid, the first removable encapsulant element comprising at least one luminescent material, the first encapsulant holding element in a lighting device that also comprises at least a first solid state light emitter, an interface between the first solid state light emitter and the first removable encapsulant element is substantially or completely without a gap, removing the first removable encapsulant element from the lighting device;
- inserting at least a second removable encapsulant element into the lighting device, and closing the first encapsulant holding element.
An encapsulant element comprising:
- a substantially transparent first material;
- and at least one luminescent material within the substantially transparent first material, the encapsulant element configured to be removably positioned relative to at least a first solid state light emitter such that an interface between the first solid state light emitter and the encapsulant element is substantially or completely without a gap, the encapsulant element non-liquid.
A method, comprising:
- removing at least a first removable encapsulant element from a lighting device that comprises at least a first solid state light emitter;
- and
- inserting at least a second removable encapsulant element into the lighting device, the second removable encapsulant element configured to be the first element that light emitted from a first solid state light emitter enters after said light is emitted from the first solid state light emitter, and with an interface between the first solid state light emitter and the first removable encapsulant element substantially or completely without a gap.
A lighting device, comprising:
- at least a first solid state light emitter;
- at least a first removable encapsulant element, the first removable encapsulant element non-liquid;
- a first holding element;
- and a second holding element, the first removable encapsulant element removably held between and encapsulated by the first holding element and the second holding element, and an interface between the first solid state light emitter and the first removable encapsulant element is substantially or completely without a gap.
A lighting device, comprising:
- at least a first solid state light emitter;
- at least a first removable encapsulant element;
- and
- at least a first support,
- the first removable encapsulant element where at least some light emitted by the first solid state light emitter enters the first removable encapsulant element,
- the first solid state light emitter on the first support,
- at least one of the first removable encapsulant element and the first support comprising at least a first flange, that is between respective portions of the other of the first removable encapsulant element and the first support.
