Embodiment Construction

[0016] This high-power LED lighting lamp with self-radiating function as shown in the figure is a creative improvement to the existing high-power LED lighting lamp with self-heating function. It includes a lamp holder with an air vent, an LED illuminator, a drive circuit assembly, a heat sink and a bulb. This creative improvement is reflected in three aspects:

[0017] First, the radiator is designed as a hollow ring-shaped fin structure, which not only uses the fin structure to increase the heat dissipation contact surface of the radiator to achieve heat dissipation, but also designs the radiator as a hollow cylindrical body, which is actually a good way for heat dissipation. A heat dissipation surface of the inner cylinder is added to the device, which will undoubtedly speed up the heat dissipation effect;

[0018] Second, the conventional disk-shaped support for installing LED chips is designed as a hollow circular ring-shaped support, so that the LED chips placed on the ho...

Abstract

The invention discloses a high-power LED lighting lamp with self-heat dissipation function. The LED lighting lamp comprises a lamp cap with exhaust holes, a LED light emitter, a driving circuit component, a radiator and a bulb shell, and is characterized in that a hollow tubular radiator (5) connecting to the lower part of the lamp cap (6) with exhaust holes, a centre central ventilating duct connecting to the lamp cap (6) and the bulb shell (3) with upper opening form the LED lighting lamp rom bottom to top and from inside to outside, wherein the inner ring shell and the outer ring shell of the bulb shell (3) are asymmetric.

Description

technical field [0001] The invention relates to an LED lighting lamp, especially a high-power LED lighting lamp with a self-radiating function, which belongs to the category of LED lighting technology. Background technique [0002] Due to the advantages of long service life, short start-up time, remarkable energy-saving effect, no ultraviolet radiation and environmental pollution, and high safety in use, LED lighting has been widely recognized and 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 LED lamp will not be dissipated, resulting in a de...
