Develop the story: design the world's most energy-efficient LED headlamps

The appearance is blue, but it emits white light. The LED headlamp developed by Japan City Light Industry was adopted by Nissan's "LEAF" (Chinese name: Listening Wind). As a late manufacturer, Shiguang Industrial pursued the performance different from other company's products in the development process.

In December 2010, Nissan Motor Co., Ltd. launched the mass production electric vehicle "LEAF". The car uses the world's lowest power LED (light-emitting diode) headlamps. At least three LEDs are required for LED headlamps that have been used before. This time, the number of LEDs was reduced to two, and the power consumption was only 23W, which was reduced to about 1/3 of the previous halogen headlamps and about 2/3 of the LED headlamps.

In addition to energy saving, the design of the lamp is also very characteristic. Previous LED headlamps used light distribution with a projection lens and had a very similar appearance.

For the first time in the world, the new LED headlamps use a reflector (mirror) to distribute light. The original design is not visible in the appearance of the light source, and although it emits white light when it is lit, it looks blue when it is turned off.

Mosquito coil incident

The development of this headlamp is Shiguang Industrial, which is under the responsibility of a group of project managers from the Research and Development Department P2P3 project.

In reviewing the situation at the time, Murakami said, "I finally realized my dream. Although Shiguang Industrial started late in LED headlights, the practical application of new technology has made technicians full of sense of accomplishment."

The direct reason for the entry of the village bridge into the city's light industry was the invitation of a senior university student. But it is also because he likes cars and motorcycles. After graduating from the Department of Mechanical Engineering at the University of Science and Technology, he entered the work of the City Light Industry. "This is because I really like to make things, I am also very interested in the lights, I once raised the brightness of the motorcycle headlights."

After entering the company in 1988, the village bridge first internship in the factory to manufacture the combined lamp. "At the time, I felt that the size of the city's optical industry was great, both for workers and equipment." Later it was assigned to the Computer Aided Engineering (CAE) department. Mold design was carried out in the department, and product manufacturing was also involved in the workshop. In the second year, in 1989, he was transferred to the R&D department. At the beginning of his tenure, he received a task.

"This work is to find out how the dirt of the car lights is generated. Because the car lights installed in the roof of the car will be stained with dust or smoke oil, in order to find a countermeasure in this regard, we must first find out the reasons."

“Because I prefer to make things, I made my own car model, ignited 10 mosquito coils, analyzed the flow of smoke and the adhesion of soot and dirt. At that time, I was too focused, and the whole research and development building was smell of mosquito coils. There is no shortage of colleagues and seniors. This episode is still unforgettable."

According to the results of the mosquito-repellent incense experiment, the village bridge reported to the car manufacturer the cause of the dirt generated by the compartment lamp. At the same time, in addition to the flow path of the smoke, the influence of static electricity on the smoke oil was also considered, and a scheme for reducing the static electricity by replacing the material was proposed. .

Since then, the village bridge has been engaged in research and development of interior lighting. He also researched and developed lighting using new light sources, and was responsible for the development of a rear combination lamp and a High Mount Stop Lamp using a Neon Discharge Lamp. However, these products were not commercialized at the end.

LED Guardrail Light barrier lights on the LED light source, there are red,yellow,green,blue,white,purple,green or colorful color, such as by microchip control, which can realize the gradient, jump, color flashing, random, alternating gradient, chase, scan flow such as color change.

It is especially suitable for the application of the billboard background, overpass bridge, river, lake guardrail, building outline and other large dynamic light belts, which can produce a rainbow gorgeous effect.The outline of the building is decorated with a guardrail, which can accentuate the effect of beautifying buildings.It has turned out to be one of the best lighting products in the world.
