Description

Piano key effect panel board atmosphere lamp

Technical Field

The utility model relates to the technical field of automobile interior small lamps, in particular to a piano key effect instrument panel atmosphere lamp.

Background

Along with the rapid development of automotive interiors, people gradually increase the requirements on automotive interiors, and more automobile types begin to introduce the design of atmosphere lamps so as to improve the technological sense and the high-grade sense of automotive interiors. Among them, the most widely used is a linear atmosphere lamp, which is disposed in a large number in the positions of an automobile instrument desk, a door trim panel, and the like.

The linear atmosphere lamp is arranged in a penetrating way, so that the length of the linear atmosphere lamp is often required to reach 1-2 meters, and the linear atmosphere lamp belongs to the ultra-long linear atmosphere lamp. If the ultra-long linear atmosphere lamp adopts an integrated design, the manufacturing process requirement is extremely high in order to ensure the brightness and the lamp efficiency, so that the manufacturing cost of the ultra-long linear atmosphere lamp is high. Therefore, the ultra-long linear atmosphere lamp is designed in a segmented mode. For the existing sectional ultra-long linear atmosphere lamp, due to the problem of structural design, the problem that two adjacent lamp bodies are often matched poorly during assembly, so that the continuity of a light band after the ultra-long linear atmosphere lamp is lighted is poor, the lamp efficiency of the atmosphere lamp is affected, the appearance continuity of the ultra-long linear atmosphere lamp is poor, and the attractiveness of the ultra-long linear atmosphere lamp is affected.

In addition, the linear atmosphere lamps are mainly classified into a hidden type linear light source atmosphere lamp and a direct display type linear light source atmosphere lamp according to the light emitting mode. Although the width of the luminous band of the hidden line light source atmosphere lamp can be close to 10mm, the brightness of the hidden line light source atmosphere lamp is generally low because the illuminated surface is generally dark and the absorbance is relatively high, and if the illuminated surface is not black or white, such as hump or brown, the finally presented color is generated to be off-color and not the wanted color. Although the direct display type linear light source atmosphere lamp can effectively solve the problems that the brightness of the hidden type linear light source atmosphere lamp is low and color cast is easy to occur, the conventional direct display type linear light source atmosphere lamp generally adopts a common linear light guide with the diameter of 3-5mm, so that the width of a luminous band is very narrow, and only 2-5mm is adopted. And, no matter be current hidden line light source atmosphere lamp, still current straight line light source atmosphere lamp, at most establish an LED respectively at the both ends of light guide, lead to the light efficiency singleness, can only discolour and turn on, do not have any third dimension, more can't realize complicated third dimension such as flowing water, lead to technological sense and high-order sense still to show inadequately.

Therefore, referring to chinese patent CN115164119a, the applicant has designed a split-type overlength stereoscopic linear atmosphere lamp, by means of the design of emitting light from the whole surface of the light emitting area with stereoscopic effect, the width of the light emitting area is greatly increased, so that the width of the light emitting area can be easily made to be centimeter-level, and then each light guiding unit can be independently lighted by matching with each independent condenser, so that the light guide can exhibit a stereoscopic effect with extremely strong stereoscopic effect, and the linear atmosphere lamp can realize complex stereoscopic effects such as running water, rhythmicity, color lump change and the like by separately configuring RGB LEDs for each condenser, so that the technological sense and the advanced sense of the linear atmosphere lamp are greatly improved.

Some host factories react to the applicant: the light guide of the existing stereoscopic linear atmosphere lamp is not only still outstanding in appearance structure, but also slightly insufficient in stereoscopic impression, and is single in color and insufficient in contrast when being used as a pure decoration for canceling PCBA. And each light guide unit is provided with an independent light condenser, each light condenser is required to be independently provided with an LED lamp bead, so that the quantity of the LED lamp beads is very high, the manufacturing cost is high, the wiring of the LED lamp beads on the PCBA is very dense, the design and manufacturing difficulty of the PCBA are high, meanwhile, the light condenser is positioned right behind a three-dimensional effect light emitting groove due to the fact that the LED lamp beads are right opposite to the light condenser, the eyes can easily see bright spots caused by the LED lamp beads, and the optical effect is always not ideal.

Solving the above problems is urgent.
