Controlling Information with Light

Value of information maximized through the control of light at will

The vast amount of information surrounding us only gains value when it is accumulated, processed,
and communicated efficiently. Light plays a significant role in various processes involved in utilizing information.
By controlling light, we can maximize the value of information and achieve efficient communication.

Turn & reverse light road projection (LED)

The combination of automotive lamp lens technology and LED device technology has enabled the energy-saving and space-saving road projection turn lamp unit.

A certain number of accidents occur at intersections with poor visibility where front lights do not currently help when turning.

With the car’s right turn signal flashing, currently a cyclist approaching from the left does not notice the car until they are somewhat closer (it takes 15 meters for the cyclist to come to a complete stop after noticing the car), resulting in a collision.

Stanley Electric offers its turn signal road projection unit to reduce these accidents.

Toward “fatal accident elimination” Reducing traffic accidents that are unavoidable with vehicles

（So that everyone who uses the road sees the same situation in the same way）

Door open/close alerts
Preventing blind spot motorcycle/bicycle accidents when turning right

Motorization, via-smartphone control, automation

Checking the remaining EV battery level
Checking weather before going out
Letting those around you know that your driving is automated driving

Increase in carsharing and ridesharing

Individualized special hospitality　Welcome & light curtains

Letting those around you know that you are going to open/close the door

Many fatal accidents caused by motorcycles being pushed into the adjacent/opposite lane due to a suddenly opened car door

Letting your surroundings know that you are going to turn

In Japan, 24% of accidents that happen with vehicles turning left involve blind spot motorcycles/bicycles.

Principle of the road laser projection system optical module
RGB laser + MEMS optical system module *MEMS (micro electro mechanical system)

Optical system

The MEMS mirror device scans laser light in two axes for projection
No optical energy wasted
RGB laser light sources are used

Features

Simple, compact optical system
Video not blurred regardless of distance [Focus-free]
Vivid RGB tri-color laser beams
Background whiteout prevented by high contrast
Low power consumption and heat generation

Laser scanning
Digital Light Processing

Communication light (mini LED)

With the spread of BEVs, design freedom with respect to the front grille of the car has increased.

Improved safety

The display allows for smoother car-human interactive communication.

Display providing communication with the vehicle's surroundings (encourages pedestrians to cross)
Improved design

The curved display with high freedom of design to fit the car body design allows you to customize your own car design at any time according to your preferences and surrounding environment.

Display highlights individuality

Feature: Flexible & high brightness display proposed

Automotive reliability: Automotive quality ensured
High brightness: Smooth message display when viewed from 2–3 m away by pedestrians
High contrast: High visibility even in outside daylight
Curved design possible
