Description

Luminous car logo

technical field

The utility model relates to a luminous car sign, in particular to a luminous car sign which emits light upwards and forms a halo effect corresponding to the sign body.

Background technique

At present, most of the products with excellent word-of-mouth already have the logo of their own brand, especially in the automobile industry, a product with a good brand can be said to be a guarantee of the product's superior performance. Therefore, in the automotive industry, for most vehicle brands such as Mercedes-Benz (BENZ), BMW (BMW), Audi (Audi), and Ferrari (Ferrari), which are currently world-renowned brands, the logo is the soul of the brand and has an unshakable quality. status.

Although "the logo is the soul of the brand", as far as the general vehicle logo is concerned, it is mostly just a flat or three-dimensional sculpture or engraving body. Although its shape and font have been specially designed, most of them can only be seen in the light Sufficient and well-sighted places can show the flavor of their products. However, when the light is weak (such as at night or in an underground parking lot), or the distance is relatively long, the effect of the general sign on displaying the product is limited, which is a shortcoming of the existing sign.

Therefore, in order to improve the above-mentioned shortcomings, the new patent case of Taiwan Patent M332241 "Illuminated Automobile Signboard" mainly has a structure of a luminous automobile signboard, which includes a body made of a light-transmitting material. , a coating layer, a substrate and a light source, wherein the rear side of the body has a chamber, the coating layer is coated on the front side of the body, so that the front side of the body has the characteristics of partial reflection and partial light transmission, the substrate Located on the back side of the main body, the light source is electrically connected to the substrate and located in the chamber of the main body, and the light projected by the light source can penetrate the coating layer and the front side of the main body to have a luminous effect, so as to increase the texture And provide the function of night recognition.

However, because the body coating layer is easy to deteriorate and fall off, it cannot provide durable use, and the light of each LED light source on the circuit board is directly projected from the front of the front mask, which is easy to be too bright due to excessive brightness. Dazzling, on the contrary, makes the logo pattern blurred, and affects the sight of vehicles coming from behind, endangering driving safety.

In order to improve the above shortcomings, in Taiwan Patent M376463 "Illuminated Automobile Logo and Its Luminous Components", an innovative structural improvement of the luminous automobile logo is proposed, as shown in FIG. 1 . In the figure, the existing luminous car logo includes a car logo body 10, and the back side of the car logo body 10 is combined with a light-emitting component 20 of the same shape. Wherein, the light-emitting assembly 20 includes a light-guiding seat 21 made of a light-guiding transparent material having the same shape as the car logo body 10, and the inner side is concavely provided with accommodating grooves 212 according to its shape, for combining with one side opposite to the plurality of accommodating grooves 212. A plurality of LED luminous bodies 221 and a circuit board 22 are accommodated, and the outer side of each LED luminous body 221 is respectively recessed with conical light diffusion grooves 213 to expand the refraction and improve the luminous effect, and cooperate with a front cover 23 corresponding to the light guide shape , to form a light-emitting component structure with a waterproof and sealed coating, providing a combination between the car logo and the car body, when each LED luminous body 221 can emit light through the projection light guide seat 21, it will form a highlight around the bottom side of the logo or the side edge of the hollow frame The luminous visual effect of the halo in the shape of the car logo further enhances its texture.

However, this kind of luminous automobile sign, due to its luminous mode, is to irradiate the light guide seat 21 at the bottom by the light emitted by the light-emitting diode, and then reflect the light to the front cover 23 by the light guide seat 21, so it emits light. The effect is less pronounced.

In addition, because the manufacturing method of this kind of luminous automobile logo is relatively complicated, all components need to be redesigned, molded and manufactured, and the previously used components cannot be shared for redesign, and the production cost is relatively high.
