A lamp with a spring-shaped heat sink comprises a driving power source (502), a heat sink (1) and an LED lamp panel (507), which are orderly connected together. The heat sink (1) comprises a thermal loading plate (20) and at least one spring-shaped heat dissipation body (10) arranged thereon. The spring-shaped heat dissipation body (10) is formed by integrally winding a spring and comprises an upper-layer spring body (110) and a lower-layer spring body (120) axially stacked on each other, a first extension section (131), a second extension section (132), a third extension section (133), a first heat conducting section (141), a second heat conducting section (142), a third heat conducting section (143) and a fourth heat conducting section(144). The upper end of the first extension section (131) is connected with the upper end of the upper-layer spring body (110) and extends to the bottom surface of the lower-layer spring body (120). An end of the first heat conducting section (141) is connected with the lower end of the first extension section (131), and coils on the inner side of the bottom surface of the lower-layer spring body (120) or circles on the outer side of same. The lamp with a spring-shaped heat sink (50) is high in heat conduction efficiency and heat dissipation efficiency, excellent in ventilation performance, low in weight and flexible in shape and dimension. |
