<p>PURPOSE: A light emitting device is provided to increase reception sensitivity of a wireless control signal by increasing the transmissivity of a wireless control signal. CONSTITUTION: A light emitting board(100) includes a driving substrate, a light emitting chip, and a signal receiver. The light emitting chip is arranged on one side of a driving plate. The signal receiver controls the light emitting chip by receiving a wireless control signal. A diffusion unit(400) includes a base film layer and a light diffusion layer. The base film layer is arranged on the upper side of the light emitting board. The light diffusion layer is formed on the upper side of a base film layer opposite to the light emitting board. The light diffusion layer has a first transmission hole on the position corresponding to the signal receiver.</p> |
