Abstract:
1. A lighting device comprising: a substrate comprising an electrically insulating layer and first and second electrodes, the first and second electrodes being spaced from each other and disposed on the electrically insulating layer; a light-emitting element mounted on the electrically insulating layer of the substrate and electrically connected to the first electrode and the second electrode of the substrate; a phosphor layer comprising a phosphor and spaced from the light-emitting element; and a light-transmitting layer with thermal conductivity that is higher than thermal conductivity of the phosphor layer, the light-transmitting layer disposed in contact with the phosphor layer, the light-transmitting layer comprises a transparent electrode layer and is configured to release static charge to the second electrode that is a cathode electrode of the substrate.
