LED lamp

Abstract

The invention provides an LED lamp, which comprises a lamp holder and a lampshade fixed to the lamp holder. A driving plate is arranged in the lamp holder, and a motor is arranged on the lamp holder; the motor is coaxial with the lampshade and the lamp holder, and an air outlet hole is formed in the lamp holder; an air inlet hole is formed in the center of the bottom of the lampshade, and fan blades capable of being driven by the motor to rotate so as to suck air from the air inlet hole and discharge the air from the air outlet hole are arranged on the motor; and a patch cylinder fixed to the end, facing one end of the air inlet hole, of the motor, coaxial with the motor and driven by the motor to rotate is arranged in the lampshade, the patch cylinder is in a cone shape, the conical tip direction of the patch cylinder faces the air inlet hole, and a plurality of LED lamp beads are arranged on the outer wall of the patch cylinder. The LED lamp has the advantages of good heat dissipating effect, good lighting effect, small size and high power.

Description

technical field [0001] The invention relates to the field of lighting equipment, in particular to an LED lamp. Background technique [0002] There are many kinds of LED lamps on the market, but the power is often affected by the heat dissipation conditions. Most of the existing LED lamps adopt passive heat dissipation and use heat dissipation fins to dissipate heat, which will make it difficult to perform well in places with poor air quality. At the same time, because LEDs are generally SMD lamp beads, the luminous angle is affected by the lens on the lamp bead, so the SMD lamp bead will be particularly dazzling when it is lit, and the visual effect is poor and it is easy to light up when lighting. Inconsistencies in local brightness are caused; at the same time, most of the existing LED lamp holders and metal screw heads are connected by burr technology, which has weak connection strength and is easy to separate.

Problems solved by technology

[0005] In the above structure, the fan blades are rotated by the motor to achieve air convection. Since the LED lights are often installed vertically, when the fan blades are working, the air can be sucked from the bottom to the top by taking advantage of the fact that the dust is easy to fall due to its own weight. It can reduce the suction of accumulated dust, and at the same time blow off the dust accumulated above the lamp holder. When the motor rotates, it drives the patch tube to rotate together, so that the LED lamp beads on the patch tube follow the fast rotation of the patch tube to form a The ring-shaped light-emitting circle improves the lighting effect and the uniformity of lighting brightness. The patch tube is made of aluminum alloy, which can effectively absorb the heat generated by the LED lamp beads and be quickly taken away by the airflow generated by the fan blades to improve heat dissipation. effect and reduce light attenuation, its own tapered structure can reduce the wind resistance when the air enters from the air intake hole, reduce the air intake resistance and further improve the heat dissipation effect; the connection part is connected with the metal screw sleeve through the first external thread, which can effectively solve the problem The disadvantage of the weak connection strength of the metal screw socket brought by the existing thorn technology is that it is easy to cause the metal screw socket to separate from the lamp holder when the LED lamp is bumped and impacted.
