An LED bulb with a double-layer lampshade comprises a lampshade main body (1), LED chips (2), a fluorescent powder layer (3) and a base (4). The lampshade main body comprises an inner lampshade (11) and an outer lampshade (12), and the inner lampshade is covered by the outer lampshade. The LED chips, the inner lampshade and the outer lampshade are arranged from inside to outside in turn. The fluorescent powder layer is coated on the inner surface of the inner lampshade which is close to the LED chips, thereby improving the reliability of the LED chips and the fluorescent powder layer. Since the LED chips are protected by the double-layer lampshade, the safety of the LED bulb is improved. |
