Abstract

The invention relates to a secure self-radiating LED lamp device, which comprises an external power connector, a lamp cup, a fan, an internal power converter, a radiator, an LED light source and a lampshade, wherein the external power connector, the lamp cup, the fan, the radiator, the internal power converter, the LED light source and the lampshade are connected together through connecting pieces to form a lamp device. The invention is characterized in that the radiator is arranged in an internal cavity at the junction of the lampshade and the lamp cup, wherein the internal cavity is isolated from a space arranged in the lower part of the lampshade and used for installing the LED light source; and a ventilation hole is arranged on the lamp cup. Since the radiator made of heat-conducting materials is arranged in the space in the lampshade, the potential safety hazards caused by the design of naked radiator are effectively avoided; since the ventilation hole is arranged on the lamp cup, the head generated during the light emission of the LED light source can be rapidly dissipated and the heat dissipation effect of the LED lamp device is greatly improved; and since the internal configuration of the radiator is reduced, the cost is reduced, the shape is reduced and the lamp device is close to the shape of the traditional bulb, technical support is provided to enable the shape of the lamp device to be close to the shape of the traditional bulb with specifications such as E14, E27 and the like, and conditions are created for the LED lamp device to be conveniently used in all kinds of illumination fields.

Description

technical field

[0001] The invention relates to an LED lamp, in particular to a safe self-radiating LED lamp. Background technique

[0002] In recent years, with the continuous improvement of LED technology, various performances of LED lamps for lighting have been greatly improved, and because LED lighting lamps have long service life, short start-up time, remarkable energy-saving effect, no ultraviolet radiation and environmental pollution , High security and other advantages, widely recognized, has become the mainstream of energy-saving lamps in the future.

[0003] However, since the LED lamp is a photoelectric device, only 15-25% of the electric energy is converted into light energy during the photoelectric conversion process, and the rest of the electric energy is almost all converted into heat energy, which increases the temperature of the LED lamp. It is the existence of this phenomenon that if the design of the radiator is poor, the heat from the light source of the...
