Description

Technical Field

[0001] The present invention relates to the technical field of LED lamps, and in particular to an LED lamp and an assembling method thereof. Background Art

[0002] Hexagonal lenses are used in stage, film, television, theater, outdoor architectural lighting, etc. Hexagonal lenses have a large light-emitting area, uniform light emission, close arrangement, and small gaps between lenses. However, the problem is that due to the small gaps between lenses, it is difficult to fix the lenses to the lamp with screws. For example, if the hexagonal lenses are installed on a metal plate and then installed on the lamp, if the metal plate is too thin, the metal plate is easy to deform, and it is difficult to ensure the flatness of the metal plate, thereby ensuring that the distance between the light-entering surface of the light guide rod on the lens and the light-emitting surface of the light source is consistent. If the metal plate is too thick, the weight and cost of the lamp will increase.

[0003] Therefore, there is an urgent need for an LED lamp and its installation process that can ensure that the hexagonal lenses are closely arranged together, make the distance between the light incident surface of each lens light guide rod consistent with the light emitting surface of the light source, and align the center of the lens with the center of the light emitting surface of the light source, while being easy to install.

[0008] A fixing assembly is used for fixing and installing two adjacent lens assemblies.

[0009] Two fixing members are provided, and the two fixing members are respectively arranged at the upper part and the lower part of the lens assembly.

[0010] Furthermore, the fixing member is provided with a guide portion.

[0011] Furthermore, it also includes a plurality of positioning posts, which enable the light-emitting surface of the lamp bead board to maintain a certain distance from the light-incident surface of the lens assembly.

Figure 4 As shown, 4a is the light-emitting surface of the LED light source, 4b is the light-entering surface of the bottom of the lens, and the distance between them is 4c. The size 4c is fixed by the positioning column 3, and the center of the light-emitting surface of the LED light source is aligned with the center of the light-entering surface of the bottom of the lens; the lens assembly 4 is used to diverge or gather the light emitted by the LED light source, and the lens assembly is provided with a plurality of them, and the plurality of lens assemblies 4 are fixedly connected by a fixing assembly 5.

[0038] The lens assembly 4 is provided with a plurality of groups, and the plurality of groups of lens assemblies are fixedly connected by a fixing assembly 5, such as Figure 5-7 As shown, the lens assembly 4 includes a lens support plate 403 and a lens 405, and the lens support plate 403 and the lens 405 are fixedly connected by screws 401. The lens support plate 403 is provided with a plurality of rivet holes, and the lens support plate 403 is fixedly connected to the fixing assembly through the rivet holes and the core-pulling rivets 402.

[0039] The fixing assembly 5 is provided with several groups, each group of fixing assemblies is composed of several fixing assemblies, and the fixing assembly includes two fixing parts 501, and the two fixing parts 501 are respectively arranged at the upper part and the lower part of the lens support plate 403, one end of the fixing part 501 is fixedly connected to the lens support plate 403 of one group of lens assemblies 4, and the other end is fixedly connected to the lens support plate 403 of another group of lens assemblies 4, that is, the two groups of lens assemblies 4 are seamlessly connected through the fixing part 501, so that the several groups of lens assemblies 4 are arranged closely without light leakage, thereby achieving the effect of uniform light, and the fixing part 501 is provided with a guide part, such as Figure 6 As shown in FIG8a, the two groups of lens assemblies are directional installed by setting a guide portion, so that the center of the light-emitting surface of the LED light source is aligned with the center of the light-incident surface of the bottom of the lens.

[0040] The lens is provided with a light guide rod and a plurality of mounting posts. The light guide rod passes through the lens support plate 403 to receive light emitted by the LED light source and guides the light into the lens.

[0041] A lens assembly method comprises the following steps:

[0042] S1: Install several mounting posts on the lens;

[0043] S2: Align the mounting post with the positioning hole of the lens support plate to mount the lens on the lens support plate to form a lens assembly;

[0044] S3: setting a fixing component between the lens components, the fixing component enables a plurality of lens components to be seamlessly connected;

[0045] S4: Align the connected lens assembly with the positioning column on the lamp body heat sink and then fix it with countersunk screws.

[0046] The following will be combined Fig. 9 Further explanation of the installation of the lens assembly 4, 16B on the lamp body heat sink represents the screw hole on the positioning column, 16A represents the countersunk hole on the lens support plate of the lens assembly 4, and a lens assembly 4 is installed on the lamp body heat sink lens assembly positioning column in the direction of the arrow, ensuring that the countersunk holes of the lens assembly 4 correspond to the screw holes on the positioning column of the lamp body heat sink lens assembly 4, and assembled with countersunk screws. Among them, 17A represents a countersunk screw. Due to the positioning function of the countersunk screw, it can be ensured that the center of the lens is aligned with the center of the corresponding LED light source light-emitting surface. At the same time, the positioning column can ensure that the distance between the light-emitting surface of the LED light source and the light-incident surface of the bottom of the lens is consistent. In the figure, 18C represents the screw hole on the positioning column. During assembly, the countersunk hole at 18A is assembled corresponding to the screw hole at 18C. 18B represents the fixing part on the lens assembly 4, one fixing part at the top and one fixing part at the bottom. 18D represents the fixing part on the lens support plate in the lens assembly. During assembly, the upper and lower fixing parts at 18B clamp the lens support plate at 18D, shaped like Fig.10As shown in the figure, 19A and 19B are assembled in the same way. 19A represents a fixing part, which is installed on the lens support plate through a core-pulling rivet. 19B represents a lens support plate. As can be seen from the figure, the fixing part clamps the lens support plate up and down to ensure that the two lenses are in the same plane, that is, it can ensure that the distance between the bottom light-entering surface of the lens on the two lens assemblies and the light-emitting surface of the LED light source is consistent. At the same time, the countersunk hole at 18A and the screw hole at 18C are assembled by countersunk screws. Due to the positioning effect of the countersunk screws, the center of the lens on the second lens assembly can be aligned with the center of the light-emitting surface of the corresponding LED light source. The installation method of the lens assembly 4 of other groups is consistent with the installation method of the lens assembly 4 described above, so it will not be repeated.
