An LED bulb with heat sink has a bulb cup that connects to external electrical power, a power supply in the bulb cup, a heat sink, an LED light source, and a bulb cover. The components are linearly connected from top to the bottom to form the complete LED bulb. The bulb has a heat sink diameter wider than the bulb cup diameter. Also, it is wider than the bulb cover diameter, and the heat sink has flat fins. The center part of the heat sink is made of metal and has extended fins to dissipate heat. The diameter of the heat sink is wider than thick, and it is flat shaped. The metal part in the center of the heat sink is flush with the fins having the same height. The fin thickness is preferably between 0.1˜2 mm. |
