Abstract
A light emitting apparatus includes a substrate, a light emitter mounted on the substrate, and a lens at least partially covering the light emitter, the lens defining a space about the light emitter. A heat sink is attached to the substrate. The heat sink is configured to dissipate heat from the light emitter via the substrate. The substrate includes an opening communicated with the space. A vent passage is at least partially defined between the heat sink and the substrate, the vent passage communicating the opening in the substrate with an exterior of the heat sink.
Claims20
A light emitting apparatus comprising:
- a substrate;
- a light emitter mounted on the substrate;
- a lens at least partially covering the light emitter, the lens defining a space about the light emitter;
- a heat sink attached to the substrate, the heat sink configured to dissipate heat from the light emitter via the substrate;
- an opening in the substrate, the opening communicated with the space;
- and
- a vent passage at least partially defined between the heat sink and the substrate, the vent passage communicating the opening in the substrate with an exterior of the heat sink.
A light emitting apparatus comprising:
- a substrate;
- an LED mounted on the substrate;
- a lens attached to the substrate, the lens defining a space about the LED between the lens and the substrate;
- a heat sink attached to the substrate, the heat sink configured to dissipate heat away from the LED via the substrate;
- an opening in the substrate, the opening communicated with the space about the LED;
- and
- a vent passage at least partially defined between the substrate and the heat sink, the vent passage communicating the opening in the substrate with an exterior of the apparatus.
A method of venting an LED light source, the method comprising:
- (a) mounting an LED on a substrate;
- (b) covering the LED with a lens to form an LED cavity about the LED, the LED cavity formed between the substrate and the lens;
- (c) attaching a heat sink to the substrate on a side of the substrate opposite the LED;
- and
- (d) providing an opening in the substrate in communication with the LED cavity and providing a vent passage at least partially defined between the substrate and the heat sink, the vent passage communicating the opening in the substrate and the LED cavity with an exterior of the heat sink.
