Among the broad range of optical technologies, the domain in which Stanley most excels is optical technology for headlamps. Considering both safety and cost performance within a reasonable range, our primary development goal is to always deliver the safest headlamps to all. If we can deliver and spread safer products at prices that are affordable for all, we will be able to reduce the rate of accidents at a global level. Declaring the continued production of such affordable products as our mission, Stanley strives day by day toward our goal of developing products that are safe, comfortable, and able to reduce traffic accidents.
Expertise in light distribution technology, independently built up by Stanley
Safety has long been considered the most important aspect of light distribution in headlamps. It is not just a matter of emitting light. What is important is to illuminate objects so that drivers can see well when driving on the road. There are many requirements regarding safety, such as not blinding the drivers of oncoming vehicle and pedestrians. For many years, Stanley has been building up a body of light distribution technologies to increase its capacity to meet these requirements. Today, we use CAD to create light distribution, using software that we have developed in-house. Constantly using things that are packed with our own expertise and improving quality in all categories, such as functionality, safety, and design, Stanley has continued to create new products that are ahead of the needs of the times.
Diverse headlamp design
The emergence of LED as a new light source has brought greater freedom to lens shapes. This has resulted in a massive leap in the diversity of headlamp design. Some cars have been given more eyes, or more original, creative shapes that are not bound by existing standards such as circles and squares. Every day, Stanley is pursuing development aimed at the kind of styling that matches the design concept of the vehicle and that will add to vehicle owners' delight in their cars.
Developing next generation headlamps in anticipation of environmental concerns and self-driving vehicles
Stanley has a long history of and confidence in our light distribution technology, which we believe to be world-class. In recent years, with environmental perspectives being added to safety and efficiency, the development of products that are more considerate of the global environment is needed.
There is also demand for technology to improve energy use efficiency and to install sensors in headlamps in anticipation of self-driving vehicles. The commercialization of such technology is still being considered, but as part of this trend, headlamps themselves will need to be made smaller. Downsizing, multiple functionality, and efficiency improvements to reduce CO2 emissions--to make these things happen, Stanley continues its research day by day, using existing technology to further increase safety, with the aim of manipulating light freely.
Revolutionary headlamps developed with optical technology
- MR Headlamp
In 1985, Stanley launched the Multi-Reflector (MR) Headlamp, a revolutionary thin headlamp for automobiles. Simply put, the MR Headlamp is a headlamp without ridges in the lens. The original function of the reflector is to collect light, but we also gave it the light diffusion and light distribution adjustment functions that are usually provided by the lens ridges, and the front lens serves only as a see-through cover. This has provided many benefits, such as greater freedom of design and increased light volume.
Subsequently, the MR Headlamp became very popular worldwide, becoming the product that any headlamp manufacturer in any country would manufacture before any other.
- ADB Headlamp
- The ADB Headlamp detects information about oncoming vehicles and pedestrians and adjusts the light patterns automatically to prevent them being blinded. Stanley became the first manufacturer in Japan to commercialize the LED matrix ADB headlamp.
- Projector Headlamp
- Like the ADB Headlamp, Stanley was the first manufacturer in Japan to launch the projector headlamp. With a round convex lens inside the lamp, it looks just like a fish eye.
Simulation technology to bring certainty to optical technology
Using simulation software Stanley have developed ourselves to respond flexibly to rapidly changing market needs
Stanley develops various products that make use of the properties of light. Optical simulation technology is found in various parts of our manufacturing to confirm the optical technology of our products. For headlamps, CG is used to simulate light distribution on the road surface (with what distribution of intensity is the light shining on the road?). The results are then quantified for evaluation purposes. This simulation software has been developed by Stanley throughout its long history of development.
