Description

Technical Field

[0001] The utility model relates to the technical field of welcome lights, in particular to a vehicle-mounted welcome light with multi-module lenses. Background Art

[0002] A welcome light is an automotive accessory whose main function is to automatically light up and project onto the ground when the driver and passengers get on and off the vehicle, so as to achieve the effects of beauty and reminding passers-by. When the car door is closed, the welcome light will automatically go out. The welcome light is usually installed at the door position, together with the reading light and the sunroof switch on the car roof. Once it is turned on, the welcome light can automatically sense and switch itself on and off. A welcome light is a new type of green light source for vehicles. It irradiates an image film through an LED light source, and then presents the image on the film on the irradiated object through the refraction of a 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 one logo pattern or text, while some users need to display multiple logo patterns or texts. 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, which affect the user experience. In addition, its structure is relatively large, occupying a large space and being inconvenient for installation.

[0004] Therefore, a vehicle-mounted welcome light with multi-module lenses is needed to improve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a vehicle-mounted welcome light with multi-module lenses, aiming to solve the above technical problems. The utility model uses two convex lenses and one concave lens to form an imaging module, which not only effectively eliminates chromatic aberration and other color differences, but also enables the field of view angle of the imaging module to reach 30 - 60 degrees. The utility model has three groups of condenser modules, film modules and imaging modules, which can project at least three groups of logo patterns or texts simultaneously, can be applied to multiple scenarios, and has high compatibility.

[0006] The overall structure is compact, occupying less space. It can project multiple patterns onto corresponding multiple independent areas, can adapt to multiple scenarios, and can also effectively eliminate color differences.

[0007] In order to achieve the above purpose, the utility model is realized through the following technical solutions:

[0008] A vehicle-mounted welcome light with a multi-module lens, comprising a lens barrel. Inside the lens barrel, a condenser module, a film module, and an imaging module are sequentially arranged from the end to the front. A set of condenser modules, a set of film modules, and a set of forming modules are combined to form a set of complete imaging modules. The condenser module includes a condenser lens; the film module includes a film and a film tray. The film tray is arranged between the condenser lens and the imaging module, and the film is embedded in the middle of the film tray; the imaging module includes a first convex lens, a concave lens, and a second convex lens.

The second convex lens protrudes towards the object side and is located between the concave lens and the inside of the front end of the lens barrel. Each set of the imaging modules is separately placed in a housing, and the projection of the logo pattern or text to the animation effect is achieved by the on and off of the LED.

[0009] Preferably, the condenser lens is a double convex lens.

[0010] Preferably, the film tray includes a film bottom tray and a film upper cover, and the film is installed between the film bottom tray and the film upper cover.
