Problems solved by technology

The heat dissipation in the market is dominated by metals, ceramics, and heat-dissipating plastics. The heat dissipation performance mainly relies on thermal radiation for heat dissipation, and the heat dissipation performance is limited; there are also a small number of LED lamps with fans, but currently LED lamps with fans are mainly used in lamps The side or bottom (upper) is designed with a through hole on a single surface, which cannot meet the dustproof requirements of the lamp; at the same time, when the lamp is normally turned upside down, the noise of the lamp is relatively large

Embodiment Construction

[0040] Such as Figure 1 to Figure 7 As shown, the first embodiment of an LED light bulb with a fan, the light bulb is a lamp with a fan to cause air circulation, including a fan 7 arranged in the lamp body, a heat dissipation shell 6 for fixing the fan 7 at the bottom, and a light fixture for fixing the heat dissipation shell 6 The shell 9; the bulb shell 9 is joined with the heat dissipation shell 6 to form an inner cavity. A sunken installation area is provided at the center above the heat dissipation shell 6, and the LED lamp body 4 is embedded in the installation area. A power supply 8 is provided in the lamp housing 9, and the power supply 8 is connected to the LED lamp body 4 and the fan 7 for power supply. At least two grooves 12 are evenly distributed on the bulb casing 9, and the side wall of each groove 12 is provided with a first ventilation hole that runs through the inside and outside of the bulb casing 9 (the inner cavity generated by the connection between the ...

Abstract

The invention relates to an LED bulb with a fan and a lamp, which belongs to the field of LED illumination. The lamp comprises a heat radiation shell, a bulb shell, an LED lamp body as well as a micro fan and a power supply which are arranged in the interior, wherein an assembly gap is arranged between the heat radiation shell and the bulb shell, and the assembly gap is matched with the heat radiation shell and the bulb shell to form an S-shaped air path for air ventilation, which increases the contact area of air flows with the bulb, particularly with the heat radiation shell and ensures that the bulb and the lamp have good heat radiation; and meanwhile, a first ventilation hole is arranged on the side wall of a groove, which ensures that the bulb has good dustproof effect, and the service life of the bulb and the lamp is prolonged.

Description

technical field [0001] The invention relates to the field of semiconductor lighting, in particular to an LED light bulb with a fan and a lamp. Background technique [0002] At present, as a part of low-carbon life, LED lamps have gradually replaced other types of lamps due to their good low power and low heat generation performance. The heat dissipation in the market is dominated by metals, ceramics, and heat-dissipating plastics. The heat dissipation performance mainly relies on thermal radiation for heat dissipation, and the heat dissipation performance is limited; The side or bottom (upper part) is designed with a through hole on a single surface, which cannot meet the dustproof requirements of the lamp; at the same time, when the lamp is normally turned upside down, the noise of the lamp is relatively large. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide an LED light bulb and lamp with a fan, which can...
