    • An LED lighting device includes a base (1), an LED light-emitting unit (2) and a lamp shade (3), wherein the LED light-emitting unit (2) and the lamp shade (3) are arranged on the base (1); the lamp shade (3) is a solid component made of a thermally-conductive material; the lamp shade (3) covers the LED light-emitting unit (2); and the inner surface of the lamp shade (3) has a light distribution surface (31) and a thermally-conductive surface (32). The LED lighting device employs a solid material having better thermal conductivity as the lamp shade (3), therefore, heat generated by the LED light-emitting unit not only can be dissipated via the base (1), but also can be transferred outwards via the lamp shade (3), thus allowing the entire device to dissipate heat in all directions, improving the heat dissipation performance of the device, and prolonging the service life of the device; due to the improvement of the heat dissipation performance, the lighting device of higher power can be manufactured without increasing the size of the device, and the lighting brightness of the device is improved, while the use range and flexibility of the LED lighting device are improved in life and industrial use.
    • 一种LED照明装置,包括基座(1),LED发光单元(2)和灯罩(3),其中,所述LED发光单元(2)和所述灯罩(3) (1); 灯罩(3)是由导热材料制成的固体部件; 灯罩(3)覆盖LED发光单元(2); 并且灯罩(3)的内表面具有配光面(31)和导热面(32)。 LED照明装置使用具有较好导热性的固体材料作为灯罩(3),因此,由LED发光单元产生的热量不仅可以经由基座(1)消散,而且还可以经由 灯罩(3),从而允许整个装置在各个方向散热,提高装置的散热性能,延长装置的使用寿命; 由于散热性能的提高,可以在不增加装置的尺寸的情况下制造更高功率的照明装置,并且改善了装置的照明亮度,同时改善了LED照明装置的使用范围和灵活性 在生活和工业上的使用。
