A high-brightness radiating LED lamp comprises a lamp cover (2), a lamp holder (1), a LED light source (3) and a circuit board (5). The LED light source (3) is provided on the circuit board (5).The LED light source (3) and the circuit board (5) are both arranged in the lamp cover (2). An aluminum radiating plate (7) is provided between the lamp holder (1) and the lamp cover (2). The lamp cover (2) and the aluminum radiating plate (7) are connected to form a seal cavity. An insulation lead (4) penetrates through the aluminum radiating plate (7) and is connected with the lamp holder (1) and the circuit board (5). A light enhancing cover (6) covering the whole LED light source is a hollow body with a cylindrical upper end and a semi-spherical lower end. The light enhancing cover (6) enhances all the light emitted by the LED light source to achieve the light enhancing effect. The provision of the aluminum radiating plate (7) enables the effective dissipation of the heat produced by the LED lamp and prolongs the service life of the LED lamp. |
