Abstract (en)
The present invention relates to the field of illumination and provides a LED lamp and an illumination device. The LED lamp includes a LED light source 1 and a power apparatus 2 supplying for the LED light source 1, wherein the LED lamp further includes a thermally conductive lamp housing 3, a thermally conductive reflective cup 4 within the lamp housing and a thermally conductive base 5 under the reflective cup. The LED light source 1 is mounted on the base which is integrally molded with the reflective cup 4 or the lamp housing 3. In the present invention a thermally conductive base 5 is added under the reflective cup 4, and the LED light source 1 is directly mounted on the base 5. All of the base 5, the reflective cup 4 and the lamp housing 3 are thermally conductive, and the produced heat may be timely and directly transferred to the reflective cup 4 and/or the lamp housing 3 by the base 5, which greatly increases the heat dissipation area and effectively improves the performance of the heat dissipation. The heat can be dissipated quickly and efficiently without increasing the complexity of the lamp, thereby improving the utilization efficiency of the original structure of the lamp and having higher practicability.
