Abstract

An LED lamp includes a housing (100), a lens (310), a lighting part (200), a lamp holder (320), a power supply (330) and a radiator (340). A cavity is surrounded by the inner wall of the housing (100). The lens (310) and the lamp holder (320) are provided at the two ends of the cavity. The radiator (340) is provided outside the housing (100). A heat insulation device (110) is provided in the cavity, and divides the cavity into the first compartment (120) and the second compartment (130). The lighting part (200) is provided in the first compartment (120) and the power supply (330) is provided in the second compartment (130). The heat insulation device (110) blocks the effect of heat generated by the lighting part (200) on the power supply (330), thus avoiding heat radiation of the lighting part (200) on the power supply (330), and hence increasing work stability of the power supply (330).
