Abstract
An LED module may include at least one LED and an indicator. The indicator may include one or more diffusing surfaces defining an angular diffusing groove. The diffusing groove may receive the LED such that the LED is at least partially located within a volume space defined by the one or more diffusing surfaces. The diffusing groove may diffuse a light emitted from the LED and incident on the one or more diffusing surface of the diffusing groove such that the light is diffused into an interior of the indicator.
Claims16
A light emitting device (LED) module, comprising:
- four LEDs;
- an indicator including an indicating plate having a rectangular shape, the indicating plate including four diffusing grooves, each diffusing groove of the four diffusing grooves defined by a separate set of one or more diffusing surfaces and formed at a central portion of separate, respective outer surfaces of the indicating plate, wherein each diffusing groove of the four diffusing grooves is configured to
- receive a separate LED of the four LEDs such that the separate LED is at least partially located within a volume space defined by the one or more diffusing surfaces of the diffusing groove, and
- diffuse lights emitted from the separate LED received into the diffusing groove and incident on the one or more diffusing surfaces of the diffusing groove such that the light is diffused into an interior of the indicating plate;
- and
- an indicating channel arranged at a central portion of the indicating plate and configured to indicate the light emitted from the four LEDs and diffused into the interior of the indicating plate.

A light emitting device (LED) module, comprising:
- four LEDs;
- an indicating plate having a rectangular frame shape including one or more inner surfaces that define a central opening, the indicating plate including four diffusing grooves, each diffusing groove of the four diffusing grooves defined by a separate set of one or more diffusing surfaces and formed at separate, respective outer surfaces of the indicating plate, wherein each diffusing groove of the four diffusing moves is configured to
- receive a separate LED of the four LEDs such that the separate LED is at least partially located within a volume space defined by the one or more diffusing surfaces of the diffusing groove, and
- diffuse lights emitted from the separate LED received into the diffusing groove and incident on the one or more diffusing surfaces of the diffusing groove such that the light is diffused into an interior of the indicating plate;
- and
- an indicating channel on the one or more inner surfaces of the indicating plate, the indicating channel configured to emit the light emitted from the four LEDs and diffused into the interior of the indicating plate.
