Abstract
The utility model relates to an LED spherical lamp heat dissipation insulating structure, in particular to a high-power LED spherical lamp heat dissipation insulating structure, which comprises a lamp holder (1), a driving power supply (4), a lamp casing, an LED lamp wick (7), a glass bulb casing (9) and slots on the periphery of the lamp casing. Besides, an insulating liner layer is arranged inside the lamp casing. The LED spherical lamp heat dissipation insulating structure adopts the scheme of adding the design of a structure for heat dissipation through convection to the lamp casing made of aluminum materials with high heat conducting coefficient. Compared with an LED spherical lamp heat dissipation insulating structure only adopting a conducting mode, the LED spherical lamp heat dissipation insulating structure remarkably improves heat dissipation performance by adopting heat dissipation through convection and heat dissipation through heat conduction. Compared with an LED spherical lamp heat dissipation insulating structure only adopting a safety distance insulating mode, the LED spherical lamp heat dissipation insulating structure remarkably improves safety performance by adopting a reinforced isolation mode through insulating media. Besides, the LED spherical lamp heat dissipation insulating structure can be widely applied to the field of LED spherical lamp illumination.
