A lighting apparatus according to an embodiment includes an optical unit and a body. The Optical unit includes a light emitting module that has a light emitting element, a reflector that controls distribution of light from the light emitting module, and a unit supporting member that supports the light emitting module and the reflector. A plurality of optical units are mounted to the apparatus body such that each optical unit is detachable. And the body includes an irradiating portion that has an opening through which the optical units irradiate light.

Lighting apparatus

An organic electroluminescence device capable of realizing both high light emitting efficiency and high reliability with an inexpensive structure is provided. The organic electroluminescence device includes an organic layer including a light emitting layer between an anode and a cathode. The anode has a laminated structure including a first layer composed of aluminum (Al) or an alloy containing aluminum as a main component and a second layer that is provided between the first layer and the organic layer and is composed of an alloy containing aluminum as a main component, and a resistance of the first layer is lower than a resistance of the second layer.

Organic electroluminescence device and display unit

According to one embodiment, an optical unit includes a light emitting module having a light emitting element, a supporting substrate supporting the light emitting module, a reflector controlling distribution of light from the light emitting module, and a heat sink thermally connected to the supporting substrate.
