Drawings
FIG. 1 is a cross-sectional view of a light-emitting structure of a conventional vehicular lamp.
Fig. 2 is a cross-sectional view of the light guide medium of the present invention with invisible appearance.
In the figure, 1, an external mask, 2, a luminous thick-wall internal lens, 3, a protective cover, 4, a lamp body and 5, a light guide.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
Comparative example:
referring to fig. 1: the traditional realization mode is shown in fig. 1, wherein the first is an external mask, the second is a luminous thick-wall internal lens, the third is a protective cover, the fourth is a lamp body, and the fifth is a luminous light guide. The light guide in fig. 1 is arranged behind the thick-walled internal lens, the light in the light guide emits light right ahead, the thick-walled internal lens is used as a next medium part for receiving light, and the light is finally transmitted through the thick-walled internal lens and then emits light to the air, so that the light is visible to naked eyes. The design scheme is applied to the traditional function, and at the moment, the light guide parts and the light guide tooth structure for guiding light on the light guide can be seen when the product is not lighted and is lighted, so that the appearance of the product when the product is not lighted is influenced to a certain degree.
At the moment, if a lamp applied to the front bumper and the grille area of the automobile can be designed, the personalized requirement of the automobile can be greatly improved, a plurality of automobiles can be subjected to personalized and familial front face design through the lamp, and familial identification at night can be realized through the optical effect, so that the pursuit of a host factory for an innovative effect is facilitated, and a special effect can be realized only by newly designing a special light-emitting lamp applied to the front bumper and the grille.
The embodiment of the application:
referring to fig. 2, a design structure with invisible appearance of light guide medium comprises a light guide 5, an external mask 1, a luminous thick-wall internal lens 2; the front upper corner of the section of the thick-wall inner lens 2 is provided with a notch for accommodating the light guide 5, and the notch enables the section of the thick-wall inner lens 2 to be L-shaped; the light guide 5 is arranged at the position of the gap; an external mask 1 for shielding the light guide 5 is fixedly arranged in front of the light guide 5; the position of the thick-wall inner lens 2, which is right corresponding to the rear part of the light guide 5, is provided with a first reflection inclined plane, a second reflection inclined plane is arranged below the first reflection inclined plane, and the second reflection inclined plane is right opposite to the light-emitting surface of the thick-wall inner lens 2.
In this embodiment, the design structure with invisible appearance of the light guide medium is arranged at the position of the front bumper of the vehicle, and the external mask 1 is a part of the front bumper of the vehicle.
In another embodiment, the design structure with invisible appearance of the light-guiding medium is arranged at the position of a vehicle grille, and the external mask 1 is a part of the vehicle grille.
In this embodiment, the external mask 1 is fixedly fitted with a thick-walled internal lens 2.
In this embodiment, the thick-walled inner lens 2 is fixedly mounted on the lamp body 4, see fig. 2.
In this embodiment, referring to fig. 2, a protective cover 3 is fixedly mounted on the lamp body 4, and the upper end of the protective cover 3 corresponds to the lower side position of the thick-walled inner lens 2.
In this embodiment, the light guide 5 is an elongated shape with a circular cross-section, and the end of the light guide 5 is provided with an LED light source, which is not shown in the drawings, but is prior art and will not affect the understanding of the skilled person.
The new implementation proposes to add 2 total reflection structures to avoid the appearance of visible light guides, i.e. light guide teeth patterns. As shown in fig. 2, 1 is an external mask, 2 is a luminous thick-walled internal lens, 3 is a protective cover, 4 is a lamp body, and 5 is a luminous light guide.
The principle of luminescence is as follows: the LED light source transmits light into the light guide 5, the light guide 5 still passing through the light guide's tooth pattern structure which can be reflected so that the light is flooded in the light guide. The thick-wall inner lens 2 in fig. 2 needs to be applied, the design of the thick-wall part is ingenious, namely, the principle of two times of total reflection is utilized to transmit light, namely 2 in fig. 2, two total reflection surfaces forming an included angle of 45 degrees with the horizontal plane are arranged on the left side, when the light guide reflects the light to the first total reflection surface, the light is reflected to the second total reflection surface from right to left after passing through the first total reflection surface, the light is reflected from top to bottom at the moment, then the light is reflected to an inner light distribution area with visible appearance through the second total reflection surface, the light is transmitted from left to right, and finally the light is captured by the outside air. The design scheme applies the optical principle of multiple total reflection, and arranges the originally visible light guide structure behind the invisible outer face cover in the design process, thereby solving the problems that the appearance of the product is influenced to a certain extent when the product is not lighted and the light guide parts and the light guide tooth structure used for guiding light on the light guide can be seen.
The above are preferred embodiments of the present invention, and those skilled in the art can make various changes or improvements on the above embodiments without departing from the general concept of the present invention, and these changes or improvements should fall within the scope of the present invention.
