Extreme Kr 001 EC light-sensitive canopy
Recently, the configuration of "color-changing canopy" has entered our field of vision, but not because the technology of this configuration has aroused people's attention, but because of a "joint statement" of the owners of Extreme Kr 001, which has caused users to discuss the color-changing canopy. Then we also take advantage of this wave of heat to talk to you about what the "color-changing sky" is all about.
<h1 class="pgc-h-arrow-right" data-track="4" > event review:</h1>
On October 23, the first batch of extreme krypton 001 commercial vehicles were delivered to the hands of users. However, in only two or three days, the owner of the extreme krypton issued a joint statement, which pointed out that "the official color-changing sky curtain legend of extreme krypton does not match the actual color of the real car".
Joint statement of the owners of Extreme Kr 001
The "EC light-sensitive canopy" mentioned in the joint statement of the owners is one of the optional installations of the Extreme Kr 001 model, priced at 10,000 yuan, while the official current preferential policy shows that the discount price for the optional configuration before December 31, 2021 is 6,000 yuan.
Previously, the extreme krypton 001 EC light-sensitive sky curtain introduction page
THE EC light-sensitive canopy can automatically sense the intensity of ambient light to change color, achieving shading and heat insulation and privacy protection. Users can also change the color of the canopy through the central control large screen and voice commands, and the ultraviolet barrier rate, SPF sun protection coefficient, and protection level are higher than the traditional sunroof.

However, at the launching ceremony of the delivery of Extreme Kr 001, extreme Kr officials had said that the current EC color change canopy was only blue, and the products that were black after the color change could not be launched until the second half of 2022. According to the official website of Guangyi Technology, the supplier of the extreme kryptonite 001 color-changing canopy, although the electrochromic (EC) sky canopy launched by the brand is available in black and blue, according to the text information on the web page: At present, the blue skylight product has been launched, and the black skylight product is expected to be launched at the end of 2022. It can be seen that in the delivery ceremony of the new car, the extreme Kr official has elaborated on the relevant issues of the discoloration canopy.
<h1 class="pgc-h-arrow-right" data-track="42" >What is a color-changing canopy? </h1>
The color of the Porthole of the Boeing 787 when the blackout function is turned on
The color-changing canopy is based on the non-openable panoramic canopy, using electrochromic glass technology. If you've flown on a Boeing 787, you're no stranger to this technology. Yes, the model's porthole shading function is the application of electrochromic technology, thus eliminating the traditional physical shading panel.
Electrochromic glass is energized will change color of the glass, after discoloration can be like Low-e (low radiation glass) to the room for thermal insulation, but it is more advanced, electrochromic glass is able to regulate its light transmittance, color shade to reduce glare, while you can control the brightness and temperature of the room through this.
Ferrari Superamerica
In the automotive industry, as early as 2005, the roof glass of the Ferrari Superamerica roadster adopted electrochromic glass technology. However, the model was the first generation of this technology, and now the technology has developed to the third generation, and it has also subdivided products with different working principles.
Application of PDLC electrochromic glass in offices
Then there are three kinds of electrochromic glass that are most widely used, namely polymer dispersible liquid crystal (PDLC), electrochromic (EC) and suspended particle (SPD). The first two technologies are used in the production models currently on sale, and the last type of technology, due to its low physical characteristics and safety (the working voltage requires 110 volts), so it rarely appears in the civilian field, so this article will not be introduced, mainly to talk to you about the application of the first two types of technology.
PDLC dimming glass:
Schematic diagram of the structure of the PDLC dimming glass
PDLC dimming glass is to add a layer of dimming film between the glass (PDLC, PolymerDispersed Liquid Crystal), which mainly works between the scattered state and the transparent state, that is, the film itself can change between the transparent and non-transparent state (the visual effect is close to the frosted glass), and the transparency is regulated by the voltage. This technology is characterized by a relatively low operating voltage, which can be opened between 12-60 volts, has high safety, and has low power consumption; while the conversion speed between transparent and opaque is relatively fast, about 1 second can be completed. This technology is also relatively mature, and most of it has been used on the privacy glass of high-end office meeting rooms, and has been commercially operating for at least two decades.
LanTu FREE
LanTu FREE changed the light sky curtain
At present, this PDLC technology is used in the Landu FREE model, and the light transmittance is designed to be 0-10, of which 0 is opaque "frosted glass" state and 10 is fully transmitted. In the opaque state, the vehicle's canopy has better privacy, and it is almost impossible to see the situation inside the car. However, in this state, there is basically no overhead field of view, and the scenery and filter effects cannot be combined.
EC dimming glass:

EC dimming glass was previously mainly used in the field of aviation and architecture, such as the porthole of the aforementioned Boeing 787 Dreamliner, and the transmittance changed linearly from transparent to deep black, which is the credit of electrogenic light technology. Ec dimming glass color change control is through a gel as a medium, applied to the gel can be a small voltage can be applied to darken it, after the power failure will restore the gel to its natural transparent state. The voltage can be precisely controlled, and by raising or lowering the voltage, you can get the light transmission that you think is more comfortable.
Extreme Kr 001
The state of the lowest light transmittance of the polar krypton 001 EC light-sensitive canopy
The EC light-sensitive canopy on the Krypton 001 is the type of technology that is applied. According to the official introduction, in the conventional state is a transparent state, in the discoloration state, the glass is blue, the ultraviolet barrier rate is as high as 99.9%, the SPF sun protection coefficient can reach 50, and the long-wave black spot effect ultraviolet UVA (wavelength is 320-420 nanometers) The transmittance is less than 6%, and the protective effect can reach the PA++++ level.

The sky canopy with EC dimming glass technology has better performance in terms of low haze value, color change range, energy consumption, stepless regulation, operating voltage and product weather resistance. However, the fly in the ointment of this technology is that its response speed is relatively slow, not as fast as the "second change" speed of PDLC dimming glass. In the official demonstration video of Extreme Kr, the change process from full light transmission to minimum transmittance takes more than 1 minute, of course, the length of the entire change time is also related to the area of glass. When the light transmittance reaches the lowest, the dimming glass is not completely invisible to the outside, and the user can still enjoy the scenery while insulation and sun protection.
<h1 class="pgc-h-arrow-right" data-track="43" >Why is the canopy of Krypton 001 blue? </h1>
The color of the EC color change canopy is mainly limited by the products provided by the configuration supplier of Extreme Kr 001, and it is still only possible to mass-produce the blue dimming glass after darkening, which is also the current state of industry technology; and the dimming glass that can present black can only be mass-produced in the second half of 2022.
At present, the Krypton App has updated the details page of the EC light-sensitive sky curtain
And as a pole krypton car in the construction of optional configuration product page, there are also certain flaws, in the can not deliver the light transmittance after the reduction of black color change canopy, the details of the optional configuration of the details of the display color is darker, so that users mistakenly think that after the canopy discoloration, it should present a state of approximate black. This has led to the incident of car owners issuing a joint statement after picking up the new car. However, at present, the Extreme Kr App has updated the details page of the configuration, and the color presented after the light transmittance is reduced is dark blue, which is closer to the state of the real car.

With the advancement of technology, configurations such as the color-changing canopy appear, which will surely give users a fresh car experience. For this kind of feature that is not popular for the time being, users must have high expectations when they first experience it. However, when the actual performance of the function is different from the previous propaganda, it is bound to react, which is also the common sentiment of people. Therefore, when promoting, car companies should try their best to present the effect closest to the performance of the real car in advance for the owner, so as not to cause users to have a psychological gap in the experience.
