On the basis of embodiment 1, in this embodiment, the automotive lamp further includes a reflector 2, and a light emitting cavity 3 is formed between the reflector 2 and the light emitting region 11; the reflector 2 has at least 2 reflector surfaces 21 located within the light-emitting cavity 3.

In the present embodiment, as shown in fig. 3, the number of the light emitters 2 is one; the structure of the reflector 2 is similar to a rectangular pyramid structure and is made of PC material, one surface of the reflector is provided with an opening 22, and the illuminant 1 is installed corresponding to the opening 22; during the actual assembly, the opening 22 may be facing downwards, i.e. the light emitter 1 is located below the reflector 2; the opening can be upward, that is, the luminous body 1 is positioned above the reflecting body;

in this embodiment, as shown in fig. 4, the reflector 2 has a U-shaped cross section; the side of the luminous body close to the luminous body 1 is provided with a first reflecting mirror surface 21a, a second reflecting mirror surface 21b and a third reflecting mirror surface 21c; therefore, as will be understood by those skilled in the art, in the embodiment of the present application, the first mirror surface 21a, the second mirror surface 21b and the third mirror surface 21c are all disposed on the integrated reflector 2; in other embodiments, the reflector surface 21 may be disposed on different reflectors 2, for example, the reflector 2 is composed of 3 independent reflectors, and the first reflector surface 21a, the second reflector surface 21b and the third reflector surface 21c are respectively disposed on three independent reflectors.

In other embodiments, the number of the light emitters 1 may also be 2 or 3, and the number of the light reflectors 2 may also be 3 or more:

for example, as shown in fig. 6, the number of the luminous bodies 1 is 2, and the reflector 2 has 3 reflector surfaces 21;

for example, as shown in fig. 7, the number of the luminous bodies 1 is 2, and the reflector 2 has 4 reflector surfaces 21;

for example, as shown in fig. 8, the number of the luminous bodies 1 is 1, and the reflector 2 has 5 reflector surfaces 21;

the above is merely a schematic structural diagram of some embodiments of the vehicle lamp, and it can be understood by those skilled in the art that, as long as the number of the luminous bodies 1 is greater than 1, the number of the reflecting mirror surfaces 21 of the reflecting body 2 is greater than 2, which is within the protection scope of the present application.

In this embodiment, at least 2 reflecting mirror surfaces 21 and at least one light emitter 1 are arranged, so that a light emitting area 11 of the light emitter 1 and each reflecting mirror surface 21 form a light emitting cavity 3; the light emitting intensity is increased by reflecting the light of the luminous body 1 for multiple times; meanwhile, in the process of adjusting the gray scale of the light emitting region 11, the control module 4 can form a three-dimensional space dynamic effect graph after the light emitted by the light emitting region 11 is reflected by the light emitting body 2, so that the visual effect is better.

In this embodiment, as shown in fig. 9, the light emitting cavity 3 has a first end 31 and an opposite second end 32, the aperture of the light emitting cavity gradually increases from the first end 31 to the second end 32, and a light outlet is formed at the second end 32.

The aperture of the light-emitting cavity 3 is arranged so that the light emitted from the light-emitting cavity 3 has profound, stereoscopic and scientific senses; the arrangement of the light-emitting cavity 3 also enables the whole light-emitting cavity 3 to form an engine nozzle, a vector transmitter, a flame, a loudspeaker, a magic box, a sound box and the like, and the shape is rich and attractive.

Based on the design that the aperture of the light emitting cavity 3 gradually increases, the light emitting region 11 is a planar region, as shown in fig. 9, a first included angle α is formed between the reflector 21 and the light emitting region 11, and the first included angle α is an acute angle. Preferably, the first included angle α ranges from 10 ° to 75 °.

In the present embodiment, the reflector 21 is a plane; in other embodiments, the reflector 21 may be a curved surface, as shown in fig. 10, each reflector 21 is a wavy curved surface; as shown in fig. 11, each mirror surface 21 is an outer convex surface, forming a convex lens effect; the shape of the reflecting mirror surface 21 can also be an inner concave surface, or a partial plane and/or a partial curved surface and/or a partial outer convex surface and/or an inner concave surface; by using the above portions in combination with the surface shapes, the light reflectance of each reflector surface 21 is further improved, thereby further increasing the luminous intensity of the lamp unit.

Preferably, as shown in fig. 12, the reflecting mirror surface 21 is provided with a raised terrace-edge structure 23, and the raised terrace-edge structure 23 can further increase the reflectivity of the reflecting mirror surface 21; in the optical cavity, the reflection effect of each convex prismatic table is stronger than that of other parts, and the convex prismatic table shines like a diamond and is obvious, so that the luminous effect similar to the diamond is formed.

In this embodiment, the reflectivity of the reflector 21 is greater than or equal to 80%, preferably greater than or equal to 95%. The forming method of the reflector 21 can optionally adopt any one of the following methods:

the method I comprises the following steps: the material of the reflector 2 may be PC, for example, and the mirror surface 21 may form a mirror effect by performing an electroplating process or PVD on the PC material; the plating material may be, for example, nickel and/or nickel-chromium alloy; or the plating material may further comprise other materials such as aluminum or silver on the basis of nickel and/or nichrome.

The second method comprises the following steps: the base material of the reflector 2 is not limited, and the reflector surface 21 can be formed by attaching a high-reflectivity metal film layer on the surface of the base of the reflector 2; the material of the metal film can be selected from a silver-aluminum film.

Regardless of the above-mentioned manner, the high refractive index can further ensure the light-emitting intensity of the car light assembly.

Wherein, in this embodiment, reflector 2 and luminous body 1 can integrative fixed connection, also can separate, specifically:

for example, the light emitting body 1 is fixedly connected with the edge of the reflector 2 correspondingly. For example, the light emitter 1 is an OLED screen, a non-light emitting surface of the OLED screen faces away from the reflector 2, the OLED screen is installed at the opening 22 of the reflector 2, and the light emitter 1 is in contact with the reflector 2; in this way, the reflector 2 can give support to the luminaire 1. The edge of the reflector 2 contacting with the luminous body 1 is turned over, and the OLED screen body is fixedly connected with the turned-over edge of the reflector through modes such as clamping, screws, gluing and hot riveting. At this time, the light emitting cavity 3 forms a closed space on the longitudinal section; the end of the light emitting cavity 3 with a relatively smaller aperture may be completely closed or may have a certain opening.

The split design is, for example, such that the light emitter 1 is suspended above the reflector 2. Wherein, luminous body 1 adopts the support mode to fix with car light lamp body or car light trim: the luminous body 1 is fixed on the bracket through the modes of clamping, screws, gluing, hot riveting and the like, and then the bracket is fixed on the decorative strip or the shell of the car lamp. At this time, the light emitting cavity 3 forms a semi-closed space with a gap on the longitudinal section; the end of the light-emitting cavity 3 with a relatively smaller caliber may be completely closed or may have a certain opening.

Example 3

On the basis of embodiment 2, in this embodiment, the light-emitting region 11 is a planar region, and the light-emitting region 11 has a light-emitting direction perpendicular to the surface thereof; the light emitting area ratio of the light emitting area 11 along the light emitting direction of any one of the reflector surfaces is more than or equal to 70%; the projected area ratio is a ratio of the projected area of the light emitting region 11 on the mirror surface 21 in the light outgoing direction thereof to the area of itself.

It can be known that the light-emitting rate is equal to the ratio of the light-emitting quantity output from the light-emitting port to the original light-emitting quantity of the light-emitting body 2, and the larger the ratio is, the higher the light intensity under the same conditions is; this application is to the injectment of light projection area ratio more than or equal to 70% for the primary light source of large scale throws at just right reflector surface, has increased the light yield of light-emitting window, has improved the light yield of car light subassembly, and then has increased the light intensity of car light.

Specifically, as shown in fig. 13, for example, corresponding to the case of the reflector 2 in fig. 5, the mirror face 21 includes a first mirror face 21a, a second mirror face 21b, and a third mirror face 21c; the included angle between the first reflector surface 21a and the second reflector surface 21b is less than or equal to 90 °, the included angle between the second reflector surface 21b and the third reflector surface 21c is less than or equal to 90 °, so that the light of the light-emitting region 11 on both sides of the first direction can be projected onto the second reflector surface 21b, the total area of the light-emitting region of the illuminant 1 is S, the light-transmitting area of the illuminant 1 on the second reflector surface 21b is S1, the light-projecting area ratio S1/S is greater than or equal to 70%, and in the embodiment, the light-projecting area ratio is 100%. In fig. 11, for ease of viewing, we have removed the portion of the reflector 2 where the third reflector face 21c is located.

As shown in fig. 12, for example, corresponding to the case shown in fig. 6, there are 2 light emitters, a first light emitter 1a and a second light emitter 1b; the area of the light emitting region of the first light emitter 1a is S _1a The area of the light emitting region of the second light emitting body 1b is S _1b (ii) a The light projection area of the light emitting area of the first light emitter 1a on the second reflector 21b is S3, and the light projection area of the light emitting area of the first light emitter 1b on the second reflector 21b is S4; light projection area ratio S3/S of first light emitter 1a _1a Equal to 85%; the light projection area ratio S4/S of the second light emitter 1b _1b Equal to 85%. For ease of illustration, in FIG. 14 we have shown the first mirror surface 21a and the third mirror surface 21c as default.

When the illuminant 1 realizes a large proportion of light projection area ratio on one of the reflecting mirror surfaces, the primary light source of the illuminant 1 is reflected with high efficiency, and the light intensity of the automobile lamp can be further effectively increased by combining the reflectivity of the reflecting mirror surface of more than 80 percent.
