The tech can identify a person who is nearly 184 feet away at night.

Buyers of the 2020 Lexus RX 450h in Europe will be able to order the brand's new BladeScan adaptive LED headlights that will be able to adjust to the road ahead even better the currently available active lights. Unfortunately, the feature won't be part of the options list in the United States.

The Bladescan LED headlights can control the illumination to within 0.7 degrees, versus 1.7 degrees for Lexus' existing adaptive lamps. This lends the ability to light areas that are often hard to see like the sides of the road. In addition, the tech offers pedestrian recognition that can spot a person at night within 183.7 feet (56 meters), versus 105 feet (32 meters) for the tech that the company offers currently.

Lexus uses interesting packaging for the Bladescan headlights. Rather than projecting directly outward, the company puts the array of LEDs in a module at the corner of the lamp, and they shine light diagonally across two rotating, blade-shaped mirrors – hence the tech's name. Switching the LEDs on and off in synchronization with the spinning mirrors lets the system put the light exactly where it needs to be. The video above demonstrates how it works.

Lexus isn't yet offering pricing details for the refreshed RX for Europe, yet, including the cost of getting the Bladescan lights.

In the U.S, the refreshed 2020 RX still comes with some significant upgrades, even if these cutting-edge headlights aren't available. The exterior styling is very similar but with minor tweaks. The interior revisions are more significant with the inclusion of Apple Carplay and Android Auto. If buyers opt for the larger, 12.3-inch screen, it comes with improved voice recognition. An updated safety suite includes better low-light pedestrian detection, lane-tracing assist, and pre-collision warning now capable of detecting bicyclists, in addition to vehicles and pedestrians.

BLADESCAN: ANOTHER BRIGHT IDEA FROM LEXUS
Lexus will mark another significant advance in automotive lighting technology with the world-first introduction of a BladeScan-type adaptive headlight system on the new RX luxury SUV. BladeScan gives both an extended field of forward illumination and more accurate lighting control to support safer driving at night and in poor weather.

The new system sustains Lexus’s fine reputation for technical innovation: it was the first car manufacturer to introduce LED headlights, on its LS flagship model in 2007, and the first to produce adaptive high-beam headlights, again initially for the LS, in 2012.

The current RX already benefits from automatic or adaptive high-beam LED lighting as part of the Lexus Safety System+ package of active safety features, to maximise headlight illumination without the risk of dazzling other road users. BladeScan goes further by providing more precise photometric control of the area of illumination in front of the car, with accuracy to within 0.7 degrees compared to around 1.7 degrees for the current technology. This means it can light up areas that would be difficult to see with a conventional high-beam system, such as the road margins, and give earlier illumination of road signs and pedestrians.

With BladeScan, pedestrian recognition at night has been improved to 56 metres in front of the RX, compared to 32 metres with the current system.

While other manufacturers have increased the number of LEDs in their headlight systems to improve lighting resolution, Lexus’s system uses a more cost-effective array of LEDs – 10 on each side of the vehicle in the case of the new RX. These are contained in a compact module located in the front corner of each headlamp, alongside the familiar triple-eye light arrangement. Rather than shining light forwards, the LEDs in each BladeScan module cast light diagonally across two blade-shaped mirrors that rotate at high speed. The precise synchronisation of the mirror rotation and the switching on and off of the LEDs creates the shading effect; the light is then reflected into a lens which casts the beam on to the road ahead, without the risk of dazzling oncoming traffic or drivers of vehicles ahead.

BladeScan will be available on the new RX from launch later this year. Details of the UK model range, specifications and prices will be announced nearer the car’s on-sale date.
