Problems solved by technology

There are also a small number of LED bulbs with fans, but at present, the LED bulbs with fans are mainly designed with air inlet / outlet holes on the side of the lamp, as disclosed by the State Intellectual Property Office of China on February 10, 2010. The patent number is CN200920135445.5, the high-power LED lamp structure with a fan whose publication number is CN201401764, adopts a side air intake structure and has a complicated structure, and due to the effect of weight, dust is easy to accumulate on the inner bottom of the bulb and cannot meet the dustproof requirements

Embodiment Construction

[0024] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0025] The invention relates to an LED light bulb with a fan, which constructs an LED light bulb with a fan in a special air circulation direction.

[0026] Such as Figure 1 to Figure 7 In the shown embodiment, said special air flow direction is produced by the arrangement of the ventilation holes 11 . The ventilation hole 11 is further divided into a first ventilation hole 11 a and a second ventilation hole 11 b, that is, the first ventilation hole 11 a and the second ventilation hole 11 b are provided on the bottom surface of the bulb housing 8 . As in the prior art, this LED bulb includes a bulb housing 8 with an interface 9, a lamp plate 2 with a single or a plurality of LED lamp holders 3 on the bottom surface of the bulb housing 8, a power supply 7 and a fan arranged in the bulb housing 8 5. The ventilation hole 11 can b...

Abstract

The invention discloses an LED bulb with a fan and a lamp, which are applied in the field of LED illumination. In the LED bulb with the fan, ventilating holes are formed on the bottom face of a shell of the bulb, so that dust can fall down under the action of the gravity and the blowing action of the fan to realize dustproof function; meanwhile, the requirement on a space of the side wall of the conventional lamp holder is reduced, and the integral structure of the bulb is compact, so that the LED bulb has better replaceability. The lamp comprises the LED bulb with the fan. Because the LED bulb has the radiating and dustproof structure, the volume of the lamp can be greatly reduced, the cost is reduced, and the service life of the bulb is ensured.

Description

technical field [0001] The invention relates to an LED lighting device with a fan, in particular to an LED light bulb and a lamp with a fan in a special air circulation direction. Background technique [0002] As a part of low-carbon life, LED lighting has gradually replaced other types of lights due to its good low power and low heat generation performance. LED lighting mainly includes LED lamps and LED bulbs. LED lamps need to replace the original lamp holder as a whole, while LED bulbs can be directly installed on the original lamp holder. Compared with the latter, the replacement cost is lower and it is easy to promote. The LED light bulbs appearing on the market are mainly made of metal, ceramics or heat-dissipating plastics, which mainly rely on heat radiation for heat dissipation, and their heat dissipation performance is limited. There are also a small number of LED bulbs with fans, but at present, the LED bulbs with fans are mainly designed with air inlet / outlet ho...
