Lamp rotating mechanism

A rotating mechanism, especially a luminaire rotating mechanism that adjusts the illumination angle of a luminaire depending on the needs of the installation environment.

The light-emitting diode emits light by using a low-voltage and high-current method, and has many advantages such as long life, low power consumption, and low heat generation. As the technology of the light-emitting diode (LED) grows, the scope of application thereof is more extensive, daily. The application of light-emitting diodes can be seen everywhere in life, and the old high-energy lamps are gradually replaced by LED lamps.

Although the light-emitting diode is a high-intensity illuminant, the volume of the light-emitting diode is relatively small, so the light-emitting angle and the irradiation area are limited. Although the illumination area of the light-emitting diode can be adjusted by providing a plurality of light-emitting diodes and a secondary lens, there are still limitations.

Because the direction of illumination of the LED tube has a strong directionality, unlike the light of the existing non-LED luminaire, the radiation has a full range of radiation. Moreover, the combination of the LED lamp and the existing lamp holder may cause the illumination direction to be inconsistent with the actual light source requirement, thereby reducing the use efficiency of the LED lamp and the willingness of the consumer to replace. Therefore, how to adapt the LED lamp to the lamp holder in the existing use and to make the illumination direction agree with the use requirement is another problem to be solved.

Therefore, it is necessary to design a mechanism for appropriately and easily adjusting the direction of illumination after the LED lamp and the existing lamp holder are installed. In addition to being able to be used in general illumination, it is also possible to achieve a special light source arrangement. This design creates a wide range of LED luminaires and enhances consumers' willingness to replace existing luminaires.

The main purpose of this creation is to provide an illumination angle that can be adjusted according to the lighting needs of various environments.

In order to achieve the above object, the specific technical means of the present invention comprises a lamp rotating mechanism coupled between a lamp and a conductive terminal, comprising a first cover, one end side being an open end combined with the lamp, and the other end side having An end cap is formed with a convex tube, an inner ring groove and an outer ring groove. The convex tube is formed at a center of the end cover, and a first wire hole is disposed in the convex tube. The inner ring groove surrounds the convex tube, and a plurality of tooth grooves are formed between the inner ring grooves and the wall surface of the convex tube, and the outer ring grooves surround the inner ring groove.

a ring is disposed in the inner ring groove, wherein at least one flange is protruded from the outer wall surface of the collar, and the at least one flange is fitted to at least one of the tooth grooves, The top edge of the collar further has a plurality of notches; a turntable seat is fixed on a side of the first cylinder cover having the convex tube, and the turntable seat defines a groove chamber corresponding to one side of the first cylinder cover. The inner wall surface of the groove chamber is formed with a plurality of bumps, and the bumps are engaged in the notches. The groove chamber is formed with a holding member corresponding to the protruding cylinder, and the retaining member is disposed at the first portion. a wire hole and abutting against an inner wall surface of the convex tube, the turntable seat further forming a limiting member toward one side of the cylindrical body, the limiting member is inserted into the outer ring groove; and a second cylindrical cover One end is an open side combined with the turntable base, and the other end is coupled to the conductive terminal.

The feature of the present invention is that after the LED lamp and the lamp holder are installed, the first cylinder can be easily rotated by applying a slight force to the lamp or the first cylinder, and the first cylinder is provided with multiple grids. The cogging is substantially equivalent to a plurality of adjustment grids, so that the adjustment can be facilitated by one rotation or one rotation at a time. When the fixture is turned into a proper position, the cogging of the first cylinder is just another The flange of the collar is snapped to naturally position the luminaire to prevent the luminaire from being displaced at will.

Another feature of the present invention is that when the lamp is mounted on the lamp holder, even if the lamp holder is not mounted properly, the lamp can be adjusted to an appropriate illumination angle by the rotating mechanism of the lamp. It does not affect the fixed state of the LED lamp and the lamp holder.

In summary, the creation does overcome the shortcomings of the prior art, and can adjust the illumination angle of the lamp according to the lighting requirements of various environments.
