[0003] However, since the LED lamp is a photoelectric device, only 15-25% of the electrical energy is converted into light energy during the photoelectric conversion process, and the rest of the electrical energy is almost 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 of the light source of the LED lamp will not be dissipated, resulting in a decrease in the light efficiency of the lamp and even the burning of the entire lamp
The heat dissipation structure design of the current high-power LED lamps is to

Example
[0025] Example 1 (natural cooling type)
[0026] Such as diagram 2-1 The self-heating LED lamp shown is a creative improvement over the existing publicly known LED lamps.
[0027] This self-heating LED lamp includes an external power connector 7, a lamp cup 6, an internal power converter 5, a radiator 3, an LED light source 2, a lampshade 1, and an internal power converter 5 with cooling fins 3- The radiator 3 of 1 is installed in the lower part of the inner cavity of the lamp cup 6, and the external power connector, the lamp cup, the internal power converter, the radiator, and the LED light source are connected through the connectors to form the entire lamp. The said fins with heat dissipation 3- 1 The radiator 3 is installed in the inner cavity of the lamp cup 6, or the upper part of the lamp cover 1, or the inner cavity of the joint part of the lamp cup 6 and the lamp cover 1. The LED light source 2 is installed at the bottom of the radiator on the side of the lamp cover 1 In ...

[0029] Example 2 (Enhanced cooling type)
[0030] For LED light source lamps with higher luminous power (see Figure 2-2 ), except that the basic structure of embodiment 1 is adopted in the basic structure: external power connector 7, lamp cup 6, internal power converter 5, radiator 3, LED light source 2, lampshade 1, and internal power converter 5, The radiator 3 with heat dissipation fins 3-1 is installed in the lower part of the inner cavity of the lamp cup 6, and the external power connector, the lamp cup, the power converter, the radiator, and the LED light source constitute the entire lamp through the connection piece. The heat dissipation fins 3-1 and the heat sink 3 are installed in the inner cavity of the lamp cup 6, or the upper part of the lamp cover 1, or the inner cavity of the joint part of the lamp cup 6 and the lamp cover 1, and the LED light source 2 is installed on the bottom of the heat sink. At the lower part of one side of the lampshade 1, a micro-fan 4 is ad...

[0031] Example 3
[0032] In practical applications, for low-power LED lamps, the radiator 3 used can also be a flat metal sheet without heat dissipation fins 3-1, which can be directly installed on the lamp cup 6 with ventilation holes 6-1 Or in the inner cavity of the lampshade, the ventilation holes 6-1 are used to produce a "revolving light" effect for natural heat dissipation.

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...
