Kebutuhan akan energi listrik dewasa ini sangatlah besar, namun seiring berkembangnya zaman, kebutuhan akan energi listrik semakin besar, sehingga dibutuhkan suatu penghematan energi listrik, supaya para penerus kita bisa merasakan manfaat energi listrik seperti kita, contohnya dalam segi penerangan, sebagian besar energi listrik saat ini digunakan untuk mensuplai penerangan, penerangan yang biasa kita pakai saat ini sangat menguras energi listrik. Saat ini kemajuan di bidang penerangan berkembang dengan pesat setelah ditemukannya LED (Light Emitting diode). lampu LED memiliki beberapa keunggulan, diantaranya, Lampu LED mengeluarkan cahaya yang terang, LED juga punya beragam keunggulan dibandingkan penggunaan lampu Pijar biasa. Keunggulan itu terutama dalam hemat energi, ramah lingkungan, serta tidak silau (ramah mata). Meskipun belum tercatat angka pastinya, keunggulan-keunggulan ini kemungkinan akan semakin menggeser pemakaian lampu Pijar biasa. Kata Kunci : energi listrik, Led, hemat energi.

Demand for electrical energy today is enormous, but as the development of the times, the need for electric energy grew, and so we need an energy saving electricity, so the successor we can feel the benefits of electrical energy such as ours, for example in terms of lighting, most electricity today this is used to supply lighting, lighting that we use today is very draining electricity. Nowadays advances in the field of lighting is growing rapidly after the discovery of LED (Light Emitting Diode). LED lights have several advantages, including, LED lights emit a bright light, LEDs also have a variety of advantages over the use of ordinary Incandescent lamps. Excellence is mainly in energy-saving, environmentally friendly, and less glare (friendly eye). Although exact numbers have not been registered, these advantages are likely to increasingly shift the use of ordinary Incandescent lamps. Keywords: electrical energy, Led, energy saving
