Description

Pole LED Light

technical field

The invention relates to a lamp, in particular to a pole-type LED lamp.

Background technique

Common pole-type LED lamps usually have a lamp head directly arranged on the lamp pole. In order to be able to adjust the lighting angle, the lamp head has a rotating head that can rotate relative to the lamp pole. For example, the Chinese utility model "Pole LED Spotlight" with the patent No. CN200820167659.6 discloses such a pole LED spotlight, which includes a light pole, a conductive member and at least one lamp cap, and the lamp cap is installed on the lamp pole. The conducting member is electrically connected with the lamp holder. The lamp holder includes a lamp tube, a luminous part and a rotating head, the luminous part is arranged between the lamp tube and the rotating head, the lamp post includes a fixed rod and a rear cover, and at least one rotating hole is opened on the fixed rod, and the rotating hole runs through the fixed rod. The rotatable head is arranged in the rotatable hole and can rotate relative to the rotatable hole, and the conducting element is electrically connected to the luminous element.

Although the pole LED spotlight in the above-mentioned patent can realize multi-directional and multi-level lighting requirements in the space by adjusting the irradiation direction of the lamp head, because the lamp head is directly set on the light pole, it cannot realize the adjustment of the lighting direction in a wide range. However, the desired lighting angle can only be obtained by rotating the rotating head of each lamp head. Not only is the operation troublesome, but the lighting range obtained by rotating the rotating head is also limited, and sometimes it is necessary to adjust the installation position of the pole. In order to make the lighting adjustment of the lamp head more flexible and easy to operate, in the prior art, all the lamp heads are separately installed on a lamp holder, and the lamp holder is connected to the light pole by hinges. The advantage of this structure is that through the lamp The rotation of the base can realize the adjustment of the lighting direction of each lamp head at the same time, the operation is very convenient, and the lighting range is wider; but the disadvantage of the current articulated lamp holder connection method is that after a period of use, there is a gap between the lamp holder and the lamp pole. The hinged connection of the lamp is easy to loosen, which makes it difficult for the lamp holder to be positioned accurately after being rotated to a preset angle, thereby affecting normal lighting use.

Contents of the invention

The technical problem to be solved by the present invention is to provide a pole-type LED lamp with a simple structure, convenient installation and effective prevention of loosening of the hinge between the lamp pole and the lamp body.

The technical solution adopted by the present invention to solve the above technical problems is: a pole-type LED lamp, including a lamp pole, a lamp body and a lamp holder, wherein the lamp holder is installed on the lamp body, and the lamp body is articulated on the On the light pole, it is characterized in that: the hinged end of the light pole is formed with a first lug, and the first lug is opened with a first threaded hole, and correspondingly, the hinged end of the lamp body is formed with a A second lug against the side wall of the first lug, a first through hole aligned with the first threaded hole is opened on the second lug, the first lug and the second The lugs are hingedly connected through the anti-loosening screws that pass through the first threaded hole and the first through hole, and there is also a thread on the light pole that communicates with the first threaded hole. The second threaded hole, the axial direction of the second threaded hole is perpendicular to the axial direction of the first threaded hole, the second threaded hole is pierced with a thread that can interfere with the thread of the anti-loosening screw Tighten the screws.
