Description

Technical Field

[0001] The utility model relates to the technical field of welcome lights, in particular to a multi-image door welcome light. Background Technique

[0002] A welcome light is an automotive accessory. Its main function is to automatically turn on and project onto the ground when the driver and passengers get on and off the vehicle, so as to play a role in beautification and reminding passers-by. When the car door is opened, the welcome light automatically turns on, and when the car door is closed, the welcome light will automatically turn off. The welcome light is a new type of green light source for vehicles. It irradiates the film through an LED light source, and then presents the image on the film on the irradiated object through the refraction of the lens. The principle of the welcome light is similar to that of a slide projector.

[0003] The welcome lights in the prior art usually can only display a single logo pattern or text, while some users need to display multiple logo patterns or text. In this case, the welcome lights that display a single logo pattern cannot meet their requirements. Moreover, the light spots projected by the commonly used welcome lights at present have obvious color differences, affecting the user experience. And for the welcome lights on the market that can project multiple images, due to the excessive additional imaging modules installed, the overall structure is also relatively large, occupying a large space and being inconvenient for installation. Content of the Utility Model

[0004] The purpose of the utility model is to provide a multi-image door welcome light, aiming to solve the above technical problems. For the multi-image door welcome light of the utility model, the condenser lens is an integrally formed structure made of coc material, which can enable the utility model to have three independent imaging modules without increasing the overall volume, occupying a small space and being convenient for installation; moreover, it can project at least three groups of logo patterns or text at the same time, with high compatibility and being applicable to multiple scenarios.

[0005] In order to achieve the above purpose, the utility model is realized through the following technical solutions:

[0006] A multi-image door welcome light, including a lens barrel. Inside the lens barrel, an imaging group, a film group and a condenser group are arranged in sequence from inside to outside. The imaging group at least includes a concave lens and two convex lenses. The condenser group includes a condenser lens. At least one double-convex condenser part is provided on the condenser lens. Each double-convex condenser part can independently form an imaging module with the imaging group and the film group. The film group includes a film clip and a film.

[0007] Further, the imaging group includes a first lens, a second lens, and a third lens from inside to outside. The first lens is a biconvex lens or a plano-convex lens convex toward the object side. The second lens is a biconcave lens. The third lens is a biconvex lens or a plano-convex lens convex toward the image side. The biconvex lens and the plano-convex lens are mainly used to converge light from a point light source or transmit an image to other optical systems.

[0008] Further, the first lens and the third lens are made of COC material, and the second lens is made of PC material. The COC material and the PC material are common materials with rich sources and low costs, which is conducive to reducing the production cost and enhancing the economic effect of the product.

[0009] Further, the first lens and the third lens are low-dispersion lenses, and the second lens is a high-dispersion lens. Such a setting can make the dispersion of the concave lens and the dispersion of the convex lens compensate each other, thereby eliminating dispersion and other chromatic aberrations, effectively improving the imaging clarity, and enhancing the user experience.

[0012] Further, the condenser lens is provided with three biconvex condenser parts, and the three biconvex condenser parts are arranged in an equilateral triangle. The biconvex condenser parts can adjust the imaging distance. By adjusting the distance between the object and the lens, the imaging position is changed to adapt to different actual needs.

[0013] Further, the condenser lens is an integrally formed structure made of COC material, so that in the case of having three independent imaging modules in the present invention, the overall volume is not increased, the occupied space is small, and it is convenient to install.

[0014] Further, condenser lens positioning grooves are provided on both sides of the upper end face of the condenser lens, and the condenser lens positioning grooves are arranged in an adapted and corresponding manner with the film positioning protrusions.

[0015] Furthermore, the lens barrel is made of PC material, and a light-transmitting hole is provided at its top. The PC material is a commonly used material with rich sources and low cost, which is beneficial to reducing the production cost and enhancing the economic effect of the product.

[0020] 4. In the present utility model, the first lens and the third lens are made of coc material, the second lens is made of pc material, the condensing lens is made of coc material, and the lens barrel is made of PC material.
