Embodiment 1

[0017] see Figure 1-2 , in an embodiment of the present invention, a welcome light lens structure includes a lens main body, the lens main body includes an upper lens 1 and a lower lens 2, and the inside of the upper lens 1 is provided with a first lens 3, a second lens 4 and a second lens Three lenses 5, the first lens 3, the second lens 4 and the third lens 5 are arranged sequentially from top to bottom;

[0018] The inside of the lower lens 2 is provided with a fourth lens 6 and an LED light 7, and the LED light 7 is arranged below the fourth lens 6;

[0019] A projection switching mechanism is provided between the upper lens 1 and the lower lens 2, and the projection switching mechanism includes an endless belt 9, which is wound on two rollers 10, and the two rollers 10 are symmetrically arranged on the left and right sides of the lower lens 2, respectively. On both sides, the center of the drum 10 is provided with a drum shaft 11, and the drum shaft 11 is connected to t...

Embodiment 2

[0030] see image 3 , different from Embodiment 1, two support rollers 21 symmetrically arranged on the left and right are arranged on the top of the lower lens 2, and the center of the support roller 21 is provided with a roller shaft, and the two ends of the roller shaft are connected to the mounting seat 22 through bearing rotation, and the mounting seat The bottom of 22 is fixedly connected to the top of lower lens 2. The flatness of the film between the lenses can be improved through the design of the two support rollers 21 , and the service life of the film can be improved no longer relying only on tension to maintain the flatness.

Abstract

The invention discloses a lens structure for a courtesy lamp. The lens structure for the courtesy lamp comprises a lens main body, wherein the lens main body comprises an upper lens and a lower lens,a first lens, a second lens and a third lens are arranged in the upper lens, and the first lens, the second lens and the third lens are sequentially arranged from top to bottom; a fourth lens and an LED lamp are arranged in the lower lens, and the LED lamp is arranged below the fourth lens; and a protection switchover mechanism is arranged between the upper lens and the lower lens, the protectionswitchover mechanism comprises an annular belt, the annular belt is wound onto two rollers, the two rollers are symmetrically arranged at the left side and the right side of the lower lens separately,a roller shaft is arranged at the center of each roller, and each roller shaft is connected with a support through a bearing. The lens structure for the courtesy lamp is capable of driving ribbon films to switch over different projection patterns through a motor, abundant in pattern, convenient in switchover, and worthy of great popularization.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to a welcome light lens structure. Background technique [0002] The welcome light is a new type of green light source for vehicles. It shines on the film through the 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 the same as that of the slide projector. The principles are similar. The LED light source part adopts advanced constant current control technology, which has uniform light emission, full light color, and long-lasting constant. The whole lamp has no pollution, no noise, and no electronic interference. The welcome light is mainly used in the position of the car door, and the welcome light has different choices of car logos according to different models. At present, there are more than 100 kinds of car logos, which are suitable for the choice of the majority ...
