Abstract

A large-angle rotating recessed lamp comprises a lamp seat and a lamp cap which is rotatablely arranged inside the lamp seat. The large-angle rotating recessed lamp is characterized in that the lamp seat is provided with a concave spherical surface, the bottom of the lamp cap is a convex spherical surface which is rotatablely matched with the concave spherical surface of the lamp seat, and a sliding groove is arranged on the concave spherical surface along the radial direction. A slide block device is placed on the bottom of the lamp cap, and the slide block device is capable of moving along the sliding groove and achieving the rotatable positioning. Compared with the prior art, the large-angle rotating recessed lamp has the advantages that the cooperation between the sliding groove on the lamp seat and the slide block device on the lamp cap enables the lamp cap to be pulled outwards to the outside of a rotating spherical surface of the lamp seat. The large-angle rotating recessed lamp is simple in structure and convenient to operate. On the premise that the insert depth of the lamp seat is not changed, the rotating angle of the lamp cap in a large range is achieved, and good lighting effects and a large irradiation range can be obtained.

In the prior art, be a kind of light fixture the Chinese utility model patent " a kind of light fixture of rotatable lamp holder " of ZL201120056256.6 discloses such as the patent No. in first to file, this light fixture comprises lamp socket and lamp holder, it is characterized in that: link to each other by rotating shaft between lamp holder and the lamp socket, rotating shaft includes four spindle noses that are crossing distribution, has the cannelure of circumferentially offering along this spindle nose on each spindle nose, being provided with on each cannelure can be with respect to the buckle of this spindle nose rotation, be positioned at the bottom that two buckles of relatively establishing on cross first straight line of rotating shaft are fixedly connected on lamp holder, two buckles of relatively establishing that are positioned on another straight line of cross of rotating shaft then are fixedly connected on relative with this lamp holder bottom and lamp socket that establish.

Above-mentioned patent adopts the rotating shaft of decussate texture to realize lamp holder with respect to the rotation of lamp socket, so that lamp holder can be adjusted in 360 degree scopes at any angle with respect to lamp socket.But, the light fixture of this patent can only be realized the rotation of 360 degree scopes in the sphere at lamp socket place, light fixture can't be moved to outward outside the lamp socket, and be installed on the laminate by damascene structures for the rotating light fixture of this class lamp holder in the above-mentioned patent is many, and the laminate thickness of commonly using in the market is 18～20mm, want that light fixture is contained on the laminate and can not through hole, the degree of depth that light fixture embeds laminate can not surpass 13mm, want to increase the degree of depth that rotational angle then often will increase embedding, this has limited illumination zone so that the light fixture of above-mentioned patent structure can't obtain larger irradiating angle under existing embedded mounting means.

The utility model content

Technical problem to be solved in the utility model is that a kind of easy to operate and large rotation angle Recessed light that the illumination adjustments angle is larger is provided for above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of large rotation angle Recessed light, include lamp socket and be placed in rotationally the interior lamp holder of this lamp socket, it is characterized in that: described lamp socket has interior concave spherical surface, described lamp holder bottom is the evagination sphere that can cooperate with the indent spherical rotation of described lamp socket, and, have a chute of radially offering on the interior concave spherical surface of described lamp socket, the bottom of described lamp holder is provided with the slide block device that can move and realize along this chute rotational positioning.

In order to realize that lamp holder is along the movement of chute, and the rotational positioning of assurance lamp holder, as preferably, described slide block device includes the first pad, the second pad and spring, wherein, the bottom of described lamp holder has the cambered outwards axle journal of axle, this axle journal is along circumferentially offering draw-in groove, described the first pad and the second pad are set in respectively on the described axle journal, described axle journal also is arranged with a jump ring that can offset with described the second pad and be embedded in the described draw-in groove, described spring between described the first pad and the second pad, and, one end of this spring and described the first pad offset, and the other end of this spring and described the second pad offset.So jump ring cooperates the axial limiting that can realize the second pad with draw-in groove, spring can so that be Elastic Contact between the bottom of the first pad and lamp socket, realizing guaranteeing the rotational positioning of lamp holder under the prerequisite that lamp holder moves along chute, prevent that lamp holder from rocking.

In order to make things convenient for the installation of power line, as preferably, but the axle journal of described lamp holder offers the axis hole that the power supply source line passes vertically.

In order to make things convenient for the installation of lamp socket, as further preferred, described lamp socket is along circumferentially being provided with and can being embedded the fixture block that cooperates with laminate, the end face of this lamp socket also be provided with a circle can with the spacing back-up ring that offsets of laminate.

Compared with prior art, the utility model has the advantage of: by the cooperation of the chute on the lamp socket and the slide block device on the lamp holder, so that lamp holder can be moved to outside the rotation spherical of lamp socket outward, simple in structure, easy to operate, under the prerequisite that does not change the lamp socket insert depth, realize lamp holder rotational angle in a wider context, can obtain better illuminating effect and larger range of exposures.
