An LED lamp comprises a substrate (1), an LED assembly (2) is disposed on the substrate (1), a surface of the LED assembly (2) is covered by a transparent heat conductor (3), and a retaining wall (4) is disposed around the LED assembly (2). The LED assembly (2) is connected to a transparent lamp cover (6), and the transparent lamp cover (6) is provided with a reflector ring. The substrate (1) and the transparent lamp cover (6) form a sealed chamber, and the LED assembly (2) is disposed in the sealed chamber. The transparent lamp cover (6) is provided with fluorescent powder mixture, and the fluorescent powder mixture is not in contact with the LED assembly (2). The LED lamp, when using a light-condensing transparent lamp cover, enables the LED lamp to implement light condensing of different angles, and when a light-spreading transparent lamp cover, enables the LED lamp to implement illumination in an angle greater than 270 degrees. |
