Description

Technical Field

[0001] The utility model belongs to the technical field of radiators, and particularly relates to a lamp radiator and a lamp applying the radiator. Background Technique

[0002] Traditional lamps use metal halide lamps or energy-saving lamps as light sources. Since they are far inferior to lamps using LED light sources in terms of energy conservation, environmental protection performance and service life, LED lamps are now usually used to replace traditional lamps. However, LED lamps are affected by the working environment temperature. Due to the small volume of the lamp body, high-power LED lamps generate more heat, and high temperature will cause an increase in LED light attenuation and reduce the service life of LED lamps.

[0003] For traditional lamp radiators, their fins and heat dissipation tube columns adopt an integrated structure. Therefore, the processing technology is difficult, the production cost of the entire radiator is high, and the ratio of the number of fins to the number of heat dissipation tube columns is fixed, and the number of fins cannot be adjusted according to actual usage requirements.

[0026] Please refer to Figure 3 and 4 As shown, the present utility model is a lamp radiator, which is formed by assembling a plurality of radially arranged heat dissipation members together, and after formation, the radiator is assembled and fitted to the top of the lamp shade 5; and the radially arranged heat dissipation members include a circular substrate 10, and a plurality of radially arranged support fins 11 are provided on the peripheral side of the circular substrate 10, and heat dissipation fins 12 are provided on one side of the support fins 11.
