Description

Technical Field

[0001] The utility model belongs to the field of vehicle lamps, and in particular relates to a combined lamp structure and a vehicle lamp. Background Art

[0002] Through-type headlights or taillights have quietly become the mainstream design popular in recent years. Through-type solutions are not only found in models of foreign car manufacturers, but also in domestic independent brand models; through-type solutions are not only found in traditional cars, but also in many new energy models. There are several implementation principles:

[0003] LED + light guide type: a light guide runs through the entire tail, and high-power LED light sources are added to the left and right ends of the light guide. This design is simple, efficient, low-cost, and basically does not occupy the taillight space. The only drawback is that the size of the light guide is limited and cannot light up a large width. For many OEMs, the through-type taillights using light guides appear too slender and cannot reflect the sense of grandeur. In addition, the light guide has its natural limitations in achieving uniform light emission.

[0004] LED+scattering material mask: This is the solution for through-type taillights of many domestic lighting manufacturers. The advantage is that the design is simple. An extra-long LED light board plus a scattering material mask can achieve the through-type effect, and the tail space occupied is relatively limited. The disadvantage is that the appearance of the through-type taillight is easily homogenized. The effect mainly depends on the scattering material on the mask. The lighting effect feels a bit stereotyped, which makes it difficult for models with unique styling requirements to stand out.

[0005] LED+small reflective bowl: a solution with a large number of LEDs. This solution is used in many luxury cars. More than 100 LED beads can be used throughout the whole process. They are first reflected and diffused by direct or reflected light, and then evenly projected through the mask. Each LED light source can be controlled individually, and a cool welcome solution can be achieved. Generally, a through-type taillight requires 160 LED beads. If each LED light source is controlled individually, it will consume a lot of power, and the wiring harness arrangement is very complicated. It is difficult to repair after a failure. If a series control is used, if one LED bead has a problem, multiple lights will not work properly, the failure rate will be greatly increased, and the product stability will decrease. Utility Model Content

[0006] In view of the above-mentioned prior art, the purpose of the utility model is to provide a more stable combination lamp structure and a vehicle lamp.

[0007] The technical solution of the utility model is implemented as follows: a combined lamp structure, comprising at least a reflector, a thick wall, a decorative ring and a circuit board, the circuit board is provided with a plurality of light sources, the thick wall is provided with a plurality of protrusions, the decorative ring is provided with a plurality of through holes and arranged corresponding to the protrusions so that when the decorative ring is installed on the thick wall, the protrusions can pass through the corresponding through holes, and the light from a light source is reflected by a reflector and passes through at least two adjacent protrusions.

[0008] The beneficial effects of such a design are: when designing through-type headlights, the number of light sources can be reduced, the stability of the headlights can be increased, a larger range can be illuminated compared to light-guided headlights, wider headlights can be designed, and compared to scattered headlights, different headlight shapes can be achieved by controlling the light source, making it more competitive in the market.

[0009] Furthermore, the reflector is provided with an open light incident side and a light emitting side, and light from the light source can enter the reflector from the light incident side and leave the reflector from the light emitting side. The plane where the light incident side is located is perpendicular or nearly perpendicular to the plane where the light emitting side is located. The reflector includes at least a first reflecting surface and a second reflecting surface. The first reflecting surface is parallel or nearly parallel to the plane where the light incident side is located, and the second reflecting surface forms a certain angle with the first reflecting surface so that the second reflecting surface can reflect part of the light from the light source onto the thick wall. Such a designed circuit board is easier to install and provides a larger installation space.

[0010] Furthermore, adjacent light sources are separated by baffles so that different light sources have independent reflection spaces to avoid light crosstalk, thus providing better lighting effects.

[0011] Furthermore, the protrusions are arranged in at least two rows, that is, at least two protrusions are arranged in one column in the vertical direction and share one light source, so that the number of light sources can be reduced.

[0012] Furthermore, the decorative ring is provided with an annular portion so that when the reflector, thick wall, decorative ring and circuit board are installed together, the annular portion surrounds the reflector, thick wall and circuit board. This design prevents light leaking from the joint between the decorative ring and the shell from affecting the lighting effect, making the lighting more beautiful.

[0013] Furthermore, the protrusions include an upper row of protrusions, a middle row of protrusions and a lower row of protrusions. The spacing between adjacent protrusions in the upper row of protrusions, the middle row of protrusions and the lower row of protrusions is the same, the sum of the number of protrusions in the upper row and the lower row is the same as the number of protrusions in the middle row, the number of protrusions in the upper row is less than the number of protrusions in the lower row, the protrusions in the upper row are arranged from the center position to both sides so that there are vacant positions on both sides, and the protrusions in the lower row are arranged from both sides to the center so that there are vacant positions in the central area. In this way, the lighting design has a more unique shape and is more beautiful.

[0014] Furthermore, the contours of the upper row of protrusions, the middle row of protrusions and the lower row of protrusions are rectangular, triangular protrusions are provided on both sides of the upper row of protrusions, and triangular protrusions are provided on both sides of the lower row of protrusions at the positions closest to the center, so that the upper row of protrusions, the middle row of protrusions and the lower row of protrusions are arranged in an arch shape as a whole, which is more natural and beautiful in the transition position.

[0015] Furthermore, the circuit board includes a left circuit board, a middle circuit board and a right circuit board. The left circuit board and the right circuit board are located above the reflector, and the middle circuit board is located below the reflector. This makes the installation position more compact and can reduce the volume occupied by the vehicle light.

[0016] Furthermore, the thick wall and the decorative ring are extended along the arc in the horizontal direction so that the protrusions and the through holes are arranged on the arc. The arc design makes the car light have a better visual effect.

[0017] Furthermore, the reflectors are arranged in a stepped manner and along an arc, the first reflective surfaces of all reflectors are parallel to each other and the second reflective surfaces of all reflectors are parallel to each other, so that the light at each position of the headlights is uniform when viewed from the same angle, and the overall look is more coordinated.

[0018] A vehicle lamp comprises the above-mentioned combined lamp structure, which not only has good stability but also has good luminous effect. BRIEF DESCRIPTION OF THE DRAWINGS
