The light emitting system includes: a means whose location can change; and multiple light emitting modules disposed in each section of the means, wherein one or more of the multiple light emitting modules is selectively turned on by a user for purpose to be recognized from outside.
Claims14
A light emitting system comprising:
- a vehicle;
- a plurality of light emitting modules disposed in the vehicle;
- and
- circuitry disposed in the vehicle and configured to control the plurality of light emitting modules,
- wherein at least one of the plurality of light emitting modules is configured to be selectively turned on by a user, via the circuitry, so as to be recognized from an outside of the vehicle,
- wherein at least one of the plurality of light emitting modules includes a light emitting device comprising:
- a first window layer configured to supply electrons;
- a second window layer configured to supply holes;
- an active layer disposed between the first window layer and the second window layer;
- a first ohmic electrode electrically connected to the first window layer;
- and
- a second ohmic electrode electrically connected to the second window layer,
- wherein the first window layer includes a first high-level doped layer having a doping level that is higher than doping levels of other portions of the first window layer, and
- wherein the first ohmic electrode is electrically connected to the first high-level doped layer.
