TWM674320U - Headlight structure (1) - Google Patents

Abstract

This invention relates to a vehicle lamp structure comprising a light source assembly, a reflective light guide, and a translucent lampshade. The light source assembly's circuit board houses an LED light source, while the reflective light guide comprises multiple reflective light-guiding regions. When the light source assembly is mounted on the reflective light guide, each LED corresponds to a reflective light-guiding region. The translucent lampshade's inner surface serves as a light-entry surface, while its outer surface serves as a light-emission surface. The light-entry surface is equipped with an optical pyramidal structure shaped like crystal facets. Consequently, when light from the LED light source is reflected by the reflective light-guiding regions and directed toward the optical pyramidal structure, it produces a crystal-like glowing effect on the light-emission surface of the translucent lampshade.

Description

Headlight structure (1)

This work relates to a vehicle lamp structure, and in particular to a vehicle lamp optical structure.

Due to their numerous advantages, including high brightness, long life, energy efficiency, and compact size, LEDs are widely used in various lighting fixtures, such as home lighting, traffic signal lights, and even vehicle taillights, turn signals, and brake lights. These fixtures all use LEDs as their light source.

However, existing LED headlights, to prevent the LED's dotted light from being visible outside the translucent headlight housing, typically employ a specially designed reflective surface on the headlight housing. This allows the LED light to be evenly distributed after being reflected by the specially designed reflective surface and projected out through the translucent headlight housing.

Although the special design of the reflective surface of the reflector can make the projected light have a certain degree of uniformity, the light projected by the translucent headlight cover only provides practical effects such as lighting and warning. The visual appearance of the light is quite dull and has no special effects. Even when the LED light source is not emitting, the effect presented by the translucent headlight cover due to the refraction of external light is also dull.

Today, the author of this invention has developed this invention in view of the shortcomings of the existing LED headlights in actual implementation.

The main purpose of this invention is to provide a headlight structure. By designing an optical pyramidal structure composed of stacked crystal facets on the light-entering surface of a translucent lampshade, the lampshade produces a shimmering effect similar to light refracted through crystal, regardless of whether the LED is emitting light or not.

The above-mentioned purpose of this creation is achieved by the following technologies:

A vehicle lamp structure includes a light source assembly, a reflective light guide, and a translucent lampshade; wherein:

The light source assembly includes a circuit board and a plurality of LEDs arranged on the circuit board;

The reflective light guide member includes a mounting surface, and a plurality of reflective light guide areas extending downward from a rear end of the mounting surface and integrally connected thereto, wherein a surface of each of the reflective light guide areas is composed of a plurality of reflective surfaces, and a notch is formed at a position on the mounting surface corresponding to each of the reflective light guide areas, wherein each of the notches corresponds to each of the LEDs on the circuit board;

The translucent lampshade includes a surrounding wall with a translucent wall surface at the front end. The wall and the translucent wall surface define a space with an opening facing backward, in which the reflective light guide is placed. The surface of the translucent wall surface facing the space is the light entrance surface, while the surface away from the space is the light exit surface. The light entrance surface is arranged with an optical pyramidal structure shaped like a crystal crystal facet and stacked in high and low levels.

In the vehicle lamp structure as described above, the light emitting surface is a smooth and flat surface.

The advantages of this creation are:

By arranging an optical pyramidal structure with crystal-like facets and stacking them in high and low layers on the light-entering surface of the translucent lampshade, the light-emitting surface of the translucent lampshade can produce a shimmering effect similar to light refracted through crystal, regardless of whether the LED is in the emitting state, thereby enhancing the warning and aesthetic effects of the car lights.

In order to provide a more complete and clear disclosure of the technical content, new objectives, and effects achieved by this creation, they are explained in detail below.

The directional terms mentioned in the following embodiments, such as "up," "down," "front," "back," "left," and "right," are merely references to the directions in the accompanying drawings for the purpose of illustration and are not intended to limit the present invention. In the following embodiments, the same or similar components will be designated by the same or similar reference numerals.

Please refer to Figures 1 to 4.

The vehicle lamp structure of this invention includes a light source assembly 1, a reflective light guide 2, and a translucent lampshade 3; wherein:

The light source assembly 1 comprises a circuit board 11, on the downwardly facing surface of which a plurality of LEDs 12 are provided. The plurality of LEDs 12 are electrically connected and can be turned on or off by an external control mechanism.

The reflective light guide 2 includes a mounting surface 21. A plurality of laterally parallel reflective light guide areas 22 extend integrally and downwardly from the rear end of the mounting surface 21. Each reflective light guide area 22 has a surface composed of a plurality of reflective surfaces 221. Notches 23 are formed on the mounting surface 21 at locations corresponding to each reflective light guide area 22. When the circuit board 11 of the light source assembly 1 is mounted on the reflective light guide 2, each LED 12 precisely corresponds to each notch 23. Light emitted by each LED 12 is projected onto its corresponding reflective light guide area 22 and then reflected by the reflective surfaces 221 within the reflective light guide area 22.

The translucent lampshade 3 comprises a surrounding wall 31. A translucent surface 32 is formed at the front end of the wall 31. The wall 31 and the translucent surface 32 define a rearwardly opening space 33. The reflective light guide 2 is positioned at the rear end of the translucent lampshade 3 and accommodated within the space 33. The surface of the translucent surface 32 facing the space 33 serves as a light-entering surface 321, while the surface facing away from the space 33 serves as a light-emitting surface 322. An optical pyramidal structure 34, formed by stacking high and low sections resembling crystal facets, is arranged on the light-entering surface 321 (see FIG. 3 ). In a preferred embodiment, the light-emitting surface 322 is a smooth, flat surface.

Accordingly, when the light emitted by each LED 12 is projected onto its corresponding reflective light-guiding area 22, it is reflected by the reflective surfaces 221 in the reflective light-guiding area 22, enters the translucent lampshade 3 through the light-entering surface 321, which is provided with an optical pyramidal structure 34 shaped like crystal facets and stacked in high and low patterns, and is then emitted from the light-emitting surface 322. Because the optical pyramidal structure 34 shaped like crystal facets and stacked in high and low patterns is provided on the light-entering surface 321, the light projected from the light-emitting surface 322 of the translucent lampshade 3 produces a sparkling effect similar to that after being refracted by crystal. In addition to enhancing the warning effect of the vehicle lights, it also provides further visual aesthetics.

The above examples are only some of the embodiments of this creation and are not intended to limit this creation. Any slight modification based on the creative spirit and characteristics of this creation should also be included in the scope of this patent.
