According to the field engineer, the luminous area is 40 square millimeters, which contains 320 columns and 80 rows of LED, and each unit can be controlled separately.
“We plan to expand this light source downwards to provide lower power luminous options to our customers.
” Jin Yuqing said.
◆ meets the long and narrow headlamp design requirements-15mm ultra-narrow lens far and near light module, image source: Ames Osram, at this stage, the narrow appearance has become one of the popular trends of headlights, far and near light also has this demand.
In response to this, Ames Osram launched a 15mm ultra-narrow lens far and near optical module.
“now more customers may ask for a lens of 10 mm or less, and we can also achieve this function.
” Jin Yuqing said.
In addition to the above, Ames Osram also demonstrated innovative solutions such as RGBi and SYNIOS ®2222 grille Demo, which not only meet basic functional requirements, but also use color and dynamic effects to enhance the personalized expression of vehicles, leading the fashion trend of automotive lighting design.
The interior atmosphere lamp is a lighting system designed to create a more comfortable and personalized driving environment.
In this ALE exhibition, Armis Osram exhibited RGBi light board, side luminous OSIRE ®E5515 film injection indicator Demo, intelligent skin RGBi atmosphere light, intelligent cabin matrix reading light, RGBi Demo, RGBi ultra-thin interior atmosphere light and other solutions, which can achieve intelligent control and high sensitivity lighting design.
OSIRE ®E3731i intelligent RGB LED can be controlled by hundreds at the same time, and each product has a built-in drive and control IC, which can communicate efficiently with the microcontroller through the SPI interface.
At the same time, OSIRE Osram also provides an open communication protocol (OSP) for the OSIRE ®E3731i product.
With OSP, the microcontroller can send instructions to each OSIRE ®E3731i and obtain the status, achieving high-precision color calibration and temperature compensation.
, image source: Ames Osram, sensors and related solutions, sensors also play an important role in modern automotive lighting design.
At this exhibition, Armis Osram exhibited RGB “side light” LED function OSIRE ®.
E5515, intelligent interior bus (OSP) and stable wavelength EEL technology specially designed for modern automobile interior lighting.
These technologies provide strong support for the next generation of automotive application innovation.
Stable wavelength EEL technology (picture source: Ames Osram), generally speaking, Ames Osram’s products are developing towards high-pixel, integrated, interactive and other new headlights, while meeting the needs of the market for low-cost and attractive styling.
Well, in the face of new market changes and developments, apart from technological innovation, what new thoughts and plans does Armis Osram have? during the exhibition, Jin Yuqing, senior marketing director for Asia-Pacific Automotive Lighting, Ames Osram, exchanged views with Gesco and other media.
Jin Yuqing, Senior Marketing Director for Automotive Lighting Asia Pacific, ◆ Osram (photo source: Ames Osram), part of the interview: general Manager Jin, can you briefly introduce the new trend and direction of automotive lighting at this stage? Jin Yuqing: in terms of exterior lighting, the pixels of headlights are getting higher and higher, which is very friendly and fashionable for the user experience.
And signal lights, including taillights, lightweight is a major trend.
In terms of interior lighting, the emphasis of atmosphere lighting is improved, and the demand for customization is increasing.
What measures does your company take to reduce the cost of ◆? Jin Yuqing: cost reduction will be achieved in a variety of ways: 1.
Through technological innovation, for example, the light source can be reduced smaller, the cost will be lower, and the luminous flux will be larger.
This is a cost reduction scheme. 2. Deepen the localization and strengthen the cooperation with local suppliers.
◆ China’s automobile industry is changing rapidly, what are the main aspects of the images and challenges in the lighting field? Jin Yuqing: first of all, with the emergence of new energy vehicles, customers’ requirements for new technologies are more and more high and diversified, such as intelligence, interaction, personalization and so on.
Second, the price of car terminals has been falling, the competition is fierce, and the pressure of price reduction is bound to be passed on to suppliers.
◆ in recent years, intelligent interaction has become a major trend of new energy lights.
In addition to taillights, many companies have begun to explore adding personalized interactive images on the front grille, but at present, the amount of application is not very large.
What do you think is the reason behind it? Jin Yuqing: at presentMainly the problem of cost, seemingly simple images, need to use thousands of LED, the price is relatively high.
◆ some car companies have been promoting some high-end lamps and lanterns in the past two years.
What is the current growth rate of high-end lamps and lanterns? Jin Yuqing: high-end lights such as DLP is definitely a development trend, but the cost is also relatively high.
Now it accounts for less than 1% of the market, but there will be a lot of room for development.
From our understanding, Micro LED will be a trend.
Since three years ago, all new models in Europe do not use DLP, all new research and development are MicroLED technology.
In China, due to the rapid development of the market, Micro LED did not have SOP three years ago, so we see that DLP is used in Weilai and so on.
What we see in the follow-up is that they will be more inclined to Micro LED.
◆ has displayed an autopilot warning lamp in accordance with European regulations.
Has this kind of lamp been discussed in China? Jin Yuqing: China has its own ideas when drawing up the standard.
as far as the application scenario is concerned, autopilot is not a fully accepted state at present.
when the light is on, pedestrians may not understand what it means.
Therefore, the application in China is not very clear for the time being.
Some ◆ headlights now have both adaptive high light and color casting function, which can only be achieved through the integration of several products.
Jin Yuqing: yes, this kind of products are more adaptive, including adaptive high light and projection headlights.
In addition to the light source, it also needs a very complex algorithm system.
It may capture the outside scene through sensors, and then know that there is a car or someone on the other side through signal analysis, and then control how its ADB is turned on.
◆ the same technical level of headlights, because the design complexity is different, the appearance is different, its cost will be very different? Jin Yuqing: it will not be very big, because for a lamp, its cost is nothing more than its particle cost, structural parts, mechanical parts and other supporting costs, labor costs are basically the same, will not be particularly high.
If the materials used are different, there may be more differences.
◆ now some enterprises integrate headlights and lidar together.
What do you think of this? Jin Yuqing: it is true that some major car light factories in China are studying this thing, but the technology is relatively difficult.
Lidar involves not only transmitting, but also receiving.
Signal processing is formed after receiving, which is a very complicated set of things.
In the past, the car light factory was only responsible for lighting.
If the lidar is integrated into it, it will be equal to the data analysis of the whole external environment of the car.
All aspects of the intelligent algorithm will become a very complex thing, and the investment will be very large.
◆, can you tell us something about the future plans of LED products for Amis Osram? Jin Yuqing: in terms of LED, the company will certainly invest more, because 52% of our applications are automotive applications, in fact, most of them are LED.
In terms of the development trend of the product, it is intelligent, and we will integrate the chip with LED, which is a trend.
There is to strive to achieve low cost.
