Luminous sign and preparation method and application thereof

Abstract

The invention provides a luminous sign and a preparation method and application thereof. The luminous sign comprises a circuit board, a light homogenizing plate and a sign body which are sequentiallyarranged; and the sign body comprises a sign substrate and an electroplated layer located on the side, close to the light homogenizing plate, of the sign substrate. The luminous sign provided by the invention has a mirror surface appearance effect in a non-lighting state, and the sign integrally emits light in a lighting state, so that the light is soft, uniform, clear and eye-catching; accordingto the luminous sign provided by the invention, light can be transmitted from the sign body, and the sign can be clearly and accurately recognized no matter in long-distance observation or in multi-angle observation; the luminous sign provided by the invention has enough waterproof and dustproof capabilities, and meanwhile, the electroplated layer is arranged in the sign body and is not in contactwith the external environment, so that the abrasion and corrosion risks can be reduced, the durability of the plated layer is improved, and the durability of the luminous sign is further improved.

Description

technical field [0001] The invention belongs to the technical field of composite boards, and relates to a luminous sign and a preparation method and application thereof. Background technique [0002] As a characteristic mark of the corporate brand, the vehicle logo is one of the essential parts of the vehicle. The existing car logo is generally made of plastic, with chrome or gold-plated exterior; the car logo is installed on the front of the vehicle, which is easy to get dirty and looks beautiful even in the daytime. , but is difficult to discern at night. With the continuous growth of consumers' demand for vehicle quality and individualization, luminous car logos, as an emerging technology, have gradually attracted the attention of major OEMs. On the one hand, the sign light can enhance the aesthetics of the vehicle, on the other hand, it can also play a warning role and improve the safety of the vehicle, which has strong safety and aesthetics. [0003] The existing lumi...

AI Technical Summary

Problems solved by technology

[0003] The existing luminescent car logo production technology is to add a luminous base to the back of the ordinary high-gloss chrome-plated car logo. The logo body cannot transmit light and has a mirror effect during the day. The disadvantages are: 1. Since the sign body has a certain thickness to achieve a three-dimensional effect, the car logo can be clearly recognized only when viewed from the front at close range, but it is difficult to recognize the car logo when viewed from a long distance or from an angle; 2. The sign body Heavy metal chromium plating is used, which is harmful to the environment

[0004] CN111114457A discloses a luminous car logo assembly, comprising: a housing; a circuit board assembly, which has a circuit board and a light source mounted on the circuit board; a light guide plate, which has a light incident surface assigned to the light source, a light The reflective surface and the light exit surface; the outer lens, which has a light-transmitting area and a non-light-transmitting area, when the light source is turned on, the vehicle logo pattern appears on the outer lens, wherein the circuit board assembly, the light guide plate and the outer lens are installed in the shell body, and the circuit board is basically oriented parallel to the main light emission direction of the luminous car logo assembly. The luminous car logo assembly provided by this patent application can achieve high light uniformity, but it still cannot achieve multi-angle or long-distance The logo is clearly visible when observing

The car logo provided by this patent application has a luminous effect, can emit light according to the predetermined car logo pattern, and has a certain decorative effect and recognition; however, the logo body is electroplated with heavy metal chromium, which is harmful to the environment
