The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

As shown in fig. 1 and 4, the annular lamp comprises an annular housing and a lamp strip installed in the housing, the housing comprises two annular half shells 1 which are mutually buckled along an annular axial direction, the lamp strip comprises a plurality of arc-shaped unit lamp strips 2, and the unit lamp strips 2 are sequentially spliced into an annular shape along the circumferential direction of the housing; a plurality of mounting seats 3 are arranged in one half shell, the peripheral part of each unit lamp strip 2 in the circumferential direction is lapped and fixed on the corresponding mounting seat 3, and the light emitting surface of each unit lamp strip 2 faces to the other half shell.

The top surface of mount pad 3 is equipped with screw 31, and the periphery of this screw 31 is annular mount table 32, and unit lamp strip 2 is taken and is put on mount table 32, and screw fit has fastening screw 4, and fastening screw 4's head compresses tightly unit lamp strip 2 and fixes on mount table 32.

The unit light bars 2 are light emitting parts of the annular lamp in the embodiment, and specifically, the unit light bars 2 can adopt LED light bars. In this embodiment, the light emitting elements of the unit light bar 2 may be packaged in various forms such as a pin type, a patch type, and a direct mount type.

Unit lamp strip 2 extends along the arc, through setting up the lamp strip into the mosaic structure of a plurality of unit lamp strips 2, can independently tailor to each unit lamp strip 2 module respectively, and needn't do wholly to annular enclosed construction's lamp strip and tailor, do benefit to nimble composing, reduce and tailor the clout to reduce the processing cost of lamp strip.

The mounting table 32 supports the unit lamp strips 2, so that the mounting positions of the unit lamp strips 2 are close to the buckling surfaces of the two half shells 1, the unit lamp strips 2 are kept away from the shell as far as possible, the shell is lightened to generate heat, the shell is prevented from being aged, and the service life of the shell is prolonged.

The mount table 32 is still as the carrier of screw 31, uses fastening screw 4 to fix unit lamp strip 2 and mount table 32, has improved the fixed stability of lamp strip, and the reliability is better. Meanwhile, the unit light bars 2 which are broken or damaged are also convenient to replace in time, and the replacement cost is reduced.

Set up mount table 32 to the annular, when satisfying fastening screw 4's installation requirement, the area of contact of minimize and unit lamp strip 2 does benefit to the heat dissipation of unit lamp strip 2, has saved parts such as heat-conducting plate, has reduced manufacturing cost.

During assembly, the unit light bars 2 are sequentially butted, are fixed on the mounting base 3 through the fastening screws 4, and then the two adjacent unit light bars 2 are sequentially connected through a circuit and then buckled with the two half shells.

In order to avoid that the strength of the unit light bars 2 is damaged by forming through holes inside the unit light bars 2, in one embodiment, as shown in fig. 4, the splicing portions of two adjacent unit light bars 2 are overlapped and fixed on the same mounting base 3, that is, the through holes for the fastening screws 4 to pass through on the unit light bars 2 are formed in the edges of the unit light bars 2, and the two ends of the unit light bars 2 in the length direction are pressed and fixed on the mounting table by the heads of the fastening screws 4. The influence to circuit on unit lamp strip 2 need not be considered during trompil like this, and unit lamp strip 2 is also difficult for the rupture simultaneously.

In the actual production process, due to machining errors or material deformation, it is difficult to splice the unit light bars into an ideal ring shape in the process of assembling the ring-shaped lamp, which causes difficulty for installation personnel. For example, the arc length of a single unit light bar 2 is too large, so that the positions of the installation seats 3 on the half-shell 1 and the spliced unit light bars cannot be aligned, and therefore, the length of the unit light bar needs to be designed with tolerance or cut according to the installation situation. In order to conveniently guide the newly spliced unit light bars when the fastening screws 4 are locked, in one embodiment, the splicing parts of two adjacent unit light bars 2 are provided with complementary clamping structures (not shown in the figure).

This block structure includes the complementary lug of shape and recess, and is concrete, can set up the lug (establishing to the head end) in 2 length direction's of unit lamp strip one end, sets up the recess (establishing to the tail end) at the other end, and each unit lamp strip end to end forms annular lamp strip. The clamping structure assists human eyes to align the two adjacent unit lamp strips, and when the fastening screws 4 are screwed, the two unit lamp strips form mutual interference at the clamping position, so that the locking operation is convenient.

In one embodiment, the two half shells are fixed by elastic buckles. The elastic buckle can be an elastic component arranged on the half shell, and can also be integrally formed with the half shell to serve as a limiting part of the half shell.

When the two half shells are buckled, the annular inserting strip 61 is inserted into the annular inserting groove 62 to provide radial limiting; meanwhile, the hook 51 is clamped in the clamping groove 52 to provide axial limiting.

Specifically, as shown in fig. 5, the annular insert 61 is a continuous protruding strip formed along the top of the fastening surface of one of the half shells, and includes a first insert 611 disposed at the inner circle of the fastening surface and a second insert 612 disposed at the outer circle of the fastening surface. First insert 611 is located at the outer edge of the inner fastening surface, and second insert 612 is located at the inner edge of the outer fastening surface.

As shown in fig. 7, a plurality of arc-shaped plates 621 are formed by extending from the inner wall of the other half-shell to the fastening surface, wherein some of the arc-shaped plates 621 are arranged at intervals along the inner ring of the half-shell, and other some of the arc-shaped plates 621 are arranged at intervals along the outer ring of the half-shell. The gap between the arcuate plate 621 and the half-shell wall forms an annular slot 62. The engaging groove 52 is disposed between two adjacent curved plates 621.

To facilitate the fastening and detaching of the half shells, in one embodiment, as shown in fig. 7, the fastening groove 52 includes a recess 521 formed by thinning the inner wall of the half shell, and a protrusion 522 formed by thickening the inner wall of the half shell, and the protrusion 522 is disposed adjacent to the recess 521. The protrusion 522 includes a first transition surface connected to the inner wall of the half shell and a second transition surface connected to the recess 521. The guide hook 51 slides into the recess 521 via the first transition surface, and the guide hook 51 slides out of the recess 521 via the second transition surface.
