[0031] The present utility model will be described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present utility model, but do not limit the present utility model in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several changes and improvements can be made. These all belong to the protection scope of the present utility model.
[0032] Embodiment 1:
[0033] The present utility model provides a vehicle lamp with a floating animation effect, as Figure 1 shown, including a plurality of light guide members 3 arranged front and rear, a PCB board 1 arranged on one side of the light incident end of the light guide member 3, an LED 2 arranged on the PCB board 1, a background member 4, and a decorative ring 5. Each light guide member 3 is configured to correspond to a group of LEDs 2, and the number of LEDs 2 in each group is one or more. The number of LEDs 2 in different groups may be the same or different. Each single LED or a string of LEDs in each group of LEDs can be individually controlled. An optical microstructure 31 is provided on each light guide member 3. The optical microstructure 31 is an optical pattern, leather pattern, tooth shape, or random pattern broken diamond, etc. The surface of the optical microstructure 31 can be aluminized to increase the lighting effect. Among them, the brightness of the light guide member 3 provided with a tooth-shaped microstructure can be increased by 5 times.
[0034] Furthermore, when the LED 2 is lit, the light enters the interior of the light guide member 3 from the light incident end of the light guide member 3 and reaches the optical microstructure 31, lighting up the optical microstructure 31. After the light enters the interior of the light guide member 3, it is totally reflected and transmitted and is reflected out of the light at the optical microstructure 31. When observing from directly in front of the light outlet of the vehicle lamp, the background member 4 is located directly behind the optical microstructure 31, and the plurality of optical microstructures 31 do not overlap. In practical applications, the background member 4 is a vehicle lamp bracket or a background layer is attached to the vehicle lamp bracket. The side of the background member 4 facing the optical microstructure 31 is dark, such as black, blue, etc. The background member 4 is arranged in black, which has a better effect than the white effect, realizing the floating effect of lighting the lamp, and thus realizing the effect of local light emission at a specified position. By providing the optical microstructure 31 on the light guide member 3 of the present utility model, the optical efficiency can be increased by 5 to 6 times, and thus the multiplexing with other functions can also be realized, such as multiplexing with the functions of the turn signal lamp and the side marker lamp, etc.
[0035] When observed from directly in front of the light-emitting opening of the vehicle lamp, a gap is provided between two adjacent optical microstructures 31. In practical applications, the optical microstructures 31 are arranged in ascending order along the light-incident surface direction. The spacing can decrease in sequence or there is no limitation. In the present utility model, the LED 2 is arranged on the PCB board 1. Light is emitted from the LED 2, enters the light-incident surface within the light guide 3, and is transmitted through total internal reflection inside the light guide 3, and is reflected and emitted at the optical pattern 4. Through the multi-layer side-by-side arrangement of the light guide 3 and the individual control of the LED 2 at the head of different light guides 3, in the way of superimposing multiple light guides, the 3D effect of the pattern and the dynamic effect to achieve the lighting animation effect are realized.
[0036] The middle of the light guide 3 in the present utility model is of a bent structure and the turning radius in the middle is more than 4 times the thickness of the light guide 3. The decorative ring 5 has a through hole for the light emission of the vehicle lamp. The decorative ring 5 except for the through hole is used to block the light guide 3. The decorative rings 5 are arranged in both the upper and lower positions of the light guide 3 for blocking to prevent the bright spots at the turning or the boundary from being visible.
[0037] It should be noted that the light guide 3 can also be made into a twisted structure, such as the effect of a DNA helix. The light guide 3 can also be directly made on the outer lens to save cost and parts. In addition, the light guide 3 can also be an optical waveguide, a thick wall, a light guide plate or other optical elements. The thickness of the light guide 3 can be uniform or gradually become thinner, for example, the thickness is 2 - 5 mm.
[0038] The patterns adopted by the optical microstructures 31 can freely define the arrangement positions. In addition to the tooth shape, different forms can also be set to control the luminous brightness and the main luminous angle to achieve different pattern combinations.
[0039] Embodiment 2:
[0040] The difference between this embodiment and Embodiment 1 is that only one light guide 3 is provided in the vehicle lamp provided in this embodiment, as Figure 2As shown in the figure, the middle of the light guide member 3 is a bent structure. The light guide member 3 includes a first light guide body 32 arranged in the upper part and a second light guide body 33 arranged in the lower part. A bent structure is formed at the connection of the first light guide body 32 and the second light guide body 33. When the LED 2 is lit, the light enters the interior of the light guide member 3 from the light incident end of the light guide member 3. The light first passes through the first light guide body 32 and then reaches the second light guide body 33 through total reflection. When the light passes through the optical microstructure 31, the optical microstructure 31 is lit. After the light enters the interior of the light guide member 3, it is transmitted by total reflection and is reflected out of the light at the optical microstructure 31. It should be noted that the optical microstructure 31 can be located on the second light guide body 33 or on the first light guide body 32. However, when the optical microstructure 31 is arranged on the first light guide body 32, the light output efficiency is lower than that when the optical microstructure 31 is arranged on the second light guide body 33. The specific position of the optical microstructure 31 can be flexibly designed according to the specific scenario to meet the requirements of the actual product.
[0041] As Figure 2 shown in the figure, the middle of the light guide member 3 is a bent structure. The bent structure is arc-shaped, and the turning radius R at the turning point in the middle of the bent structure is more than 4 times the thickness d of the light guide member (3). In this embodiment, the optical microstructure 31 is arranged on the second light guide body 33. The starting position of the optical microstructure 31 is at a distance L from the end of the turning structure of the light guide body, where L is greater than 2.5 times the thickness d of the light guide member (3) to obtain better uniformity and thus improve the light emission efficiency.
[0042] Take Figure 1 as an example, the working principle of the present utility model is as follows:
[0043] First, light up the first LED 2. The light passes through the interior of the light guide member 3, is reflected by the optical microstructure 31 area, the optical microstructure 31 area is lit, and light is emitted to display a specified pattern. Then light up the second LED 2. The light passes through the interior of the light guide member 3, is reflected by the optical microstructure 31 area, the optical microstructure 31 area is lit, and light is emitted to display a specified pattern. The LED 2 can be lit from the inside out, or according to the design requirements, from the outside in. Taking the background color blue of the background member 4 as an example, the pattern area of the optical microstructure 31 is in the shape of a bird. The achieved effect is that the bird is flying in the blue sky. In practical applications, different dynamic effects can be designed according to the requirements. Through the suspended dynamic effect of the present utility model, the lighting of the lamp is made more cool, enhancing the beauty and high-class sense of the vehicle lamp.
