Embodiment Construction

[0018] 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:

[0019] 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;

[0020] 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, an LED light emitter, a driving circuit component, a radiator and a bulb shell, and is characterized in that the radiator is a hollow cylinder; the LED light emitter is an annular light emitter consisting of an annular bracket and an LED chip; the bulb shell is an annular body with upper opening; the annular body consists of a central ventilating duct at the middle part, and an inner ring shell and an outer ring shell which are asymmetric; the radiator is suspended in the centre at the lower part of the lamp cap by a retaining plate, and the lower part of the radiator is joined to the inner ring shell which is also fixed and connected with the retaining plate, so an integrated self-heat dissipation device which consists of the central ventilating duct of the bulb shell, a hollow passage of the radiator and the exhaust holes formed on the outer wall of the lamp cap from bottom to top is formed; the annular light emitter is arranged at the lower part of the radiator; and an integrated self-heat dissipation LED lighting lamp which consists of an axial ventilating duct in the radiator, of which the upper part is connected with the lamp cap, and the exhaust holes formed on the outer wall of the lamp cap from bottom to top and from inside to outside is formed.

Description

technical field [0001] The invention relates to an LED lighting lamp, in particular to a high-power LED lighting lamp with a self-radiating function, which belongs to the LED lighting technology category. 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 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 from the light source of the LED lamp will not be dissipated, resulting in a...
