Technical Field

[0001] The utility model belongs to the technical field of projection lamps, and in particular relates to a modular projection lamp. Background Art

[0002] Car projection lights are a type of car lighting technology that can project patterns and logos onto the road surface, aiming to enhance the visibility and safety of drivers. Car projection lights are not only used for lighting and warning, but also for displaying the brand, logo, model and exclusive patterns of the vehicle, adding a more recognizable exterior design to the vehicle. This personalized display method has made car projection lights increasingly valued by lighting manufacturers, OEMs and end consumers, and has a huge market space.

[0003] At present, the existing automotive projection lamps are difficult to install due to the limited space inside the car, which is not conducive to assembly, disassembly, maintenance and use. At the same time, they occupy a large space and are not conducive to the use of compact cars.

[0004] In order to solve the above problems, a modular projection lamp is proposed in the present application. Utility Model Content

[0007] The utility model is a modular projection lamp, comprising: a module shell, and projection components are all installed inside the module shell;

[0008] The projection assembly includes a first lens, which is located inside one end of a module housing. A light source is arranged outside the first lens. A second lens, a third lens and a bracket are also arranged inside the module housing. The second lens, the third lens and the bracket are arranged in sequence from the end of the module housing away from the first lens to the end adjacent to the first lens.

[0009] Furthermore, a protruding bump is disposed above the first lens and the bracket, and a convex seat for engaging and connecting the bump is disposed above one end of the module housing.

[0010] Furthermore, a film with an adjustable pattern is arranged inside the bracket.

[0011] Furthermore, a protruding first clamping block is provided at one end of the bracket, and an open slot is formed between adjacent first clamping blocks.

[0012] Furthermore, a protruding second clamping block is provided at the other end of the first lens, and an open slot is formed between adjacent second clamping blocks.

[0013] Furthermore, the second clamping block forms a clamping connection corresponding to the open slots between adjacent first clamping blocks.

[0014] The utility model has the following beneficial effects:

[0015] The utility model uses a projection module composed of multiple lenses, structural parts and film sheets, and uses LED as a light source. It only needs to adjust the pattern on the film sheet to project the desired light pattern. It can be used on various vehicles and other occasions. The module has a small size, strong versatility, and convenient pattern adjustment. Compared with the existing projection lamp, it has the characteristics of smaller size, stronger versatility, better projection effect and stronger variability of projection pattern.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0026] See also Figure 1-4 As shown, the utility model is a modular projection lamp, comprising: a module housing 2, in which projection components are installed, and can be matched with different circuit boards to adapt to installation in various structural spaces;

[0027] The projection assembly includes a first lens 1, which is located inside one end of a module housing 2. A light source 5 is arranged on the outside of the first lens 1. A second lens 6, a third lens 7 and a bracket 8 are also arranged inside the module housing 2. The second lens 6, the third lens 7 and the bracket 8 are arranged in sequence from the end of the module housing 2 away from the first lens 1 to the end adjacent to the first lens 1, so as to achieve the effect of reducing the overall structure, making the size smaller and occupying less space, and being suitable for use in various compact vehicles and other occasions.

[0028] A protruding bump 3 is disposed above the first lens 1 and the bracket 8, and a boss 4 for engaging with the bump 3 is disposed above one end of the module housing 2, so that the installation position accuracy of the internal components can be improved through such engagement.

[0029] The bracket 8 is provided with a film sheet 9 with an adjustable pattern inside. The desired light pattern can be projected by simply adjusting the pattern on the film sheet.

[0030] A protruding first clamping block 10 is disposed at one end of the bracket 8 , and an open slot is formed between adjacent first clamping blocks 10 .

[0031] A protruding second clamping block 11 is disposed at the other end of the first lens 1 , and an open slot is formed between adjacent second clamping blocks 11 .

[0032] The second clamping block 11 corresponds to the open slot between the adjacent first clamping blocks 10 to form a clamping connection.

[0033] It can be understood that compared with the existing projection lamps, the overall structure of the utility model is reduced, so that the module size is smaller and more versatile, and the projection effect is better. The convenient graphic adjustment makes the projected graphic more variable. Only by adjusting the graphic on the film, the desired light type can be projected. It can be used in various vehicles and other occasions.

[0034] A specific application of this embodiment is: when in use, first place the second lens 6, the third lens 7, the first lens 1 and the bracket 8 in order, and then adjust the required film 9 and circuit board structure according to different use requirements and structural space, and then directly install the projection module with the circuit board at the required position through screws or other mounting structures, and then cover the module housing 2 to the outside so that the protrusion 3 is engaged and installed inside the protrusion 4, and finally fix the circuit board with LED to the module housing 2 through screws and positioning columns, and it can be used after the circuit is connected. The structure is simple and compact, which greatly reduces the occupied space and makes the overall size smaller and suitable for various vehicles and other occasions.
