[0016] Figure 1 It is a schematic structural diagram of a door bottom lamp according to an embodiment of the present utility model. Detailed Embodiments

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used herein in the specification of the present utility model are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0019] Figure 1 Schematically shows the structure of a door bottom lamp according to an embodiment of the present utility model.

[0020] As Figure 1 shown, a door bottom lamp includes a rear cover 1, and a plurality of lenses, a PCBA board 3 and a film 8 can be installed in the rear cover 1. Figure 1In the figure, a mask 13 can be installed at the lower end of the back cover 1, an LED lamp can be installed on the PCBA board 3, and multiple lenses, PCBA board 3 and film 8 are installed in the back cover 1. At the same time, the multiple lenses, PCBA board 3 and film 8 can be covered by the mask 13, so that the components in the back cover 1 form a seal.

[0021] In addition, from Figure 1 It can be seen that the film 8 can be installed between multiple lenses. The light emitted by the LED lamp passes through some lenses, is transmitted through the film 8, and passes through the remaining lenses to emit the light to the mask 13 and pass through the mask.

[0022] In this embodiment, in the field of automotive lighting, film 8 is an important material, which is mainly used to adjust the flux of light and achieve a specific lighting effect. Specifically, film 8 is a thin film material with a multi-layer structure, which includes layers of different materials and thicknesses. These layers can adjust optical properties such as light transmission, reflection and absorption according to design requirements.

[0023] Film plays a particularly important role in car lights. When the light from the light source (usually an LED) is focused by a lens, the film further adjusts the color and quantity of the light to produce the desired lighting effect. This allows car lights to be bright, full and have a specific color, improving the vehicle's recognition at night and increasing driving safety.

[0024] In this embodiment, there are five lenses, namely, from top to bottom, the first lens 6, the second lens 7, the third lens 9, the fourth lens 10 and the fifth lens 11, and the film 8 is arranged between the second lens 7 and the third lens 9. Thus, light can be focused by multiple lenses to prevent diffuse reflection of light from affecting the overall effect.

[0025] In this embodiment, if Figure 1 As shown, a lens holder 12 is also included, and multiple lenses and film 8 are installed in the lens holder 12. The lens holder 12 can fix and support multiple lenses and film 8.

[0026] In this embodiment, if Figure 1 As shown, a silicone pad 4 is also included. The silicone pad 4 is installed above the first lens 6 and the silicone pad 4 is arranged below the PCBA board 3.

[0027] The silicone pad 4 mainly plays the role of sealing and shock absorption in the car lamp.

[0028] In this embodiment, if Figure 1 As shown, it also includes a light guide plate 2, which is arranged between the back cover 1 and the mask 13, and can conduct light. The light guide plate 2 uses the principle of light conduction, and through a specific design, light can be emitted from the side, thereby playing a warning role.

[0029] The application of the light guide plate 2 in the automobile lamp is mainly reflected in achieving specific lighting effects and signal functions. The light guide plate uses the principle of light conduction and can evenly distribute the light emitted by the light source to the entire board surface through a specific design, thereby achieving a uniform lighting effect.

[0030] In this embodiment, if Figure 1 As shown, the light guide plate 2 is connected by screws 5 .

[0031] In this embodiment, if Figure 1 As shown, the fourth lens 10 is provided with a protrusion, and the third lens 9 is provided with a groove, and the protrusion can be inserted into the groove, so that the fourth lens 10 and the third lens 9 are closely fitted together.

[0032] In the utility model, since a plurality of lenses are provided, the plurality of lenses focus and transmit the light emitted by the LED lamp, so that the light will not be scattered to the side positions, and the LED lamp can be spread more efficiently.

[0033] In addition, the PCBA board, multiple lenses and film boards in the utility model are in a sealed state, dust and water will not enter the shell, and the overall structure is ingenious, small in size, light in weight and long in service life.

[0034] In the present invention, the light emitted by the LED lamp passes through some lenses, is transmitted through the film 8, and passes through the remaining lenses, and then is emitted to the mask 13, and is transmitted through the mask, that is, the light can be emitted downward, playing the role of projection, and at the same time, the light guide plate 2 can conduct the light. The light guide plate 2 uses the principle of light conduction, and through a specific design, the light can be emitted from the side, thereby playing the role of warning.

[0035] The present utility model is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present utility model fall within the protection scope of the present utility model.
