Abstract: “Solid State Lighting (SSL) becomes one of the most important products due to their energy efficiency compared to conventional type lighting. Electroluminescence (EL) whether organic EL (also known as OLED) or inorganic EL are becoming increasingly important technology because of their potential applications for display and domestic lighting. Inorganic EL lamp is a capacitor-based electronic device technically known as Light Emitting Capacitor (LEC), while currently well-known LED lamp is a diode-based, where both of them have their own advantages. The advantages of SSL compared to conventional gas discharge lighting are they are very low power consumption, safe (non-toxic material used) and flexible design. The research is focused on development of LEC for domestic lighting purpose, and as an alternative for energy saving solid state lighting. One of its advantage is it can be generated using bi-directional current path such as from AC supply while LED and OLED only have one or unidire”
