June, the grand opening of the 25th Shanghai International Film Festival, as the official partner, star designated car Cadillac pure electric SUV
LYRIQ also made a stunning appearance on the red carpet. Adhering to Cadillac’s car-making concept of “art and technology”, Ruige has brought the art of light and shadow to the extreme. As Cadillac’s sincere effort to create a new benchmark in the luxury pure electric market, ROHM’s PLEXIGLAS® molding compound is used for the turn signals of the exterior rearview mirrors and the ultra-long through-type tail lights “Flying Light”. The design, materials and details reflect Cadillac’s consistent luxury requirements.
Less is More: PLEXIGLAS®
Edgelightcreates a unique look for turn signals
First of all, Ruige has a distinctive exterior rearview mirror turn signal: the appearance is simple and smooth, without the common light guide tooth structure on other turn signals. This is due to the use of PLEXIGLAS®
The Edgelight side-emitting specification, combined with a small amount of LED light sources on the right side, can evenly light up the entire light strip. The use of this special PMMA (polymethyl methacrylate) material for the turn signal has another advantage: the mold structure is simple, which saves the design and manufacture of light guide structures, avoids tedious optical simulation and debugging, and can help parts production Providers shorten development time.
Entry is luxury: PLEXIGLAS®Neutral gray creates an art of light and shadow that is suitable for both movement and stillness
Compared with the details of the turn signals, the “Flying Light Wing” taillight group is attractive at first sight with its dazzling shape. The ultra-long through-type taillights extend from the rear of the car to both sides, and go upward until they meet the C-pillar, so that the windshield and the triangular windows on both sides are integrated, which is avant-garde and atmospheric. When not lit, the light gray cover across the rear and sides of the car is wrapped by a piano-gloss black frame, showing delicately arranged LED units and radium-carved stripes on the sides. When the welcome lights are turned on, the super-long tail lights are lit up in an orderly manner from top to bottom and from outside to inside, presenting a “light-by-light” effect, full of novelty and ritual. When the turn signal is turned on, the slender side light strips and the 7 breakpoint LED units light up synchronously, which can effectively remind the surrounding and rear drivers between breaths and breaths, and has an amazing aesthetic feeling.
The taillight housing of Raegel uses PLEXIGLAS® neutral gray as the main body and PLEXIGLAS high-gloss black® frame. This proven combination of materials can help automotive lighting designers realize hidden designs. Before the tail lights are lit, the casing is smoked and integrated with the large-area rear window. After lighting, the casing with high light transmittance almost 100% presents the true color of the light source. The color effect is perfectly rendered.
Infrared-transparent plexiglass for laser welding®neutral gray
In response to the emerging trend of penetrating shapes, 3D shapes and other complex structures in the automotive lighting field, ROHM has recently launched a new model with higher infrared transmittance based on the existing PLEXIGLAS® neutral gray specifications. . In addition to giving automotive parts an outstanding appearance, this new product can also be used for laser welding on the premise of meeting the regulations on signal color of car lights, ensuring processing accuracy and avoiding problems such as stress cracking caused by other welding methods, so as to achieve maximum The unique creativity of the designer.
PLEXIGLAS® materials with infrared transmission specifications have higher red light transmittance, which contributes to the sustainable development of the auto parts industry. With this material, there is no need to add additional LED light sources or increase the voltage, but the same light output can be obtained, thereby meeting regulatory requirements and protecting the safety of drivers and passengers.
Liu Guomin, general manager of ROHM Molding Compounds Asia, said: “Over the past 90 years, ROHM has become a huge driving force for innovative applications in many industries with PLEXIGLAS® products. In response to the demand for personalized, intelligent and sustainable development of automotive lighting in recent years , we are also constantly launching new products and applications to help customers in the automotive industry achieve new growth.”
