Detailed Embodiments

[0022] Refer to Figure 1 - Figure 6As shown in the figure, the technical solution adopted in this specific embodiment is as follows: It includes a lens bottom plate 1 and a lens 2. The lens 2 is arranged at the bottom of the lens bottom plate 1. Four long fixing columns 3 are arranged at the four corners of the lens bottom plate 1. A fixing screw hole 31 is arranged on the long fixing column 3. An installation hole 12 is arranged in the middle of the lens bottom plate 1. A limiting layer 13 is arranged on the front side of the installation hole 12 to avoid outward. An ultrasonic melting groove 14 is arranged on one side of the limiting layer 13. When a traditional lens is installed, the lens module of the lamp has been installed on the lamp base. And to improve the accuracy and tightness of the connection with the lens, at least four copper columns need to be arranged on the lamp base or the lens module for the installation of the lens module. During installation, the lens of the lens module usually faces upward, and the lens is placed downward to align with the copper columns for connection and installation. During this process, when screws or some debris fall, they will damage the lens. Therefore, in this embodiment, four long fixing columns are arranged on the lens bottom plate, and the lens module does not need to be pre-installed on the lamp base. During installation, the lens bottom plate is placed with its plane facing downward, the lens of the lens module faces downward and aligns with the long fixing columns, and the lens module is lowered and passed through the long fixing columns to limit the lens module and also perform calibration;

[0023] When placed above the lens, since two first short fixing columns 4 are symmetrically arranged in the middle of the lens bottom plate 1 and the first short fixing columns 4 are located between two adjacent lenses 2, and two second short fixing columns 5 are arranged at the diagonal corners of the lens bottom plate 1 and the second short fixing columns 5 are located inside the long fixing columns 3, the installation hole positions of the lens module match the two groups of short fixing columns. The short fixing columns position the lens module, and the lens module can be fixed on the lens bottom plate by tightening the screws, completing the installation of the lens module. The assembly steps are few, the assembly is simple, and the lens will not be damaged during the assembly process, thus effectively improving the production speed and production efficiency;

[0024] When the lens module is installed, the lamp housing can be installed. When a traditional lamp housing is installed, glue needs to be applied at the connection position with the middle of the lens bottom plate to play a sealing role and also increase the connection tightness. However, the operation is relatively troublesome and it is easy to have uneven glue application. Therefore, in this embodiment, an ultrasonic melting groove is arranged outside the installation hole in the center of the lens bottom plate. When the connection part of the lamp is clamped into the ultrasonic melting groove, an ultrasonic device is used for melting operation to complete the fusion of the lamp housing and the lens bottom plate, improving the sealing effect, also improving the operation speed and reducing the operation difficulty.

[0025] More specifically, the surface of the lens base plate 1 is provided with a bead surface 11, and the bead surface 11 is composed of a number of rough semi-circular beads 111. The surfaces of the bases of some traditional lenses are smooth structures, which are not easy to be colored. When in use, the light transmission is relatively obvious and the internal structure can be faintly seen. Therefore, a glass plate is arranged outside the lamp housing and silk-screened for coloring and blocking, resulting in a poor visual effect and a high cost. Therefore, in this embodiment, a bead surface is provided, and the bead surface is composed of a number of rough beads. Different color coatings can be printed on the bead surface, which can not only block the internal structure but also achieve a certain color-making effect, and also save the production cost. In this embodiment, the bead surface is silk-screened with ink for blackening treatment.

[0026] More specifically, fixing holes 15 are provided at the four corners of the lens base plate 1. The fixing holes 15 penetrate through the lens base plate 1 and are located outside the long fixing posts 3. The fixing holes are used for connecting and fixing with the lamp housing.

[0027] More specifically, a light guide groove 21 is provided at the bottom of the lens 2, and the light guide groove 21 is the light incident side.

[0028] More specifically, the top of the lens 2 is an outgoing light surface 22, and the outgoing light surface 22 is a smooth mirror surface.

[0029] The working principle of the present utility model: When installing the lamp, the lens module is connected and limited to the long fixing posts 2 on the lens base plate 1. At this time, the front of the lens module faces the side of the lens 2. Then, the first short fixing post 4 and the second short fixing post 5 are inserted into the fixing holes of the lens module and fixed with screws. During the installation of the lens module, since the lens surface is facing downwards, the falling objects accidentally generated during installation will not damage the lens. After the lens module is fixed, the whole is installed on the lamp base through the long fixing posts 2, and the screws are tightened for fixation, initially completing the installation of the lens module. Finally, the lamp housing part is installed. The connecting posts on the lamp housing are aligned with the fixing holes for positioning and insertion, and then the middle connecting part is aligned with the ultrasonic melting groove 14 and inserted. It is melted by an ultrasonic device, and there is no need to perform glue dotting for fixation and sealing. Finally, tightening the screws can complete the assembly of the whole lamp, and the installation is more convenient and fast.

[0030] The above is only used to illustrate the technical solution of the present utility model and not to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present utility model should be covered within the scope of the claims of the present utility model as long as they do not depart from the spirit and scope of the technical solution of the present utility model.
