Everlight's new LED street light has kept the fireflies in the urban glow

It is not difficult to see fireflies in the city! The dream of Everlight Electronics to let people see fireflies in the city has finally come true.

In order to successfully reproduce the fireflies in Daan Forest Park, Yiguang has become one of the important promoters.

This time, Yiguang is responsible for the firefly eco-pool lighting equipment, especially for the retinal habits of fireflies, and designed LED street lights with special wavelengths. This kind of light source is visible to humans, but fireflies are invisible and will not affect the retina development of fireflies. The Friends of the Da'an Forest Park Foundation participated in the International Firefly International Conference in the United States, and strived to win the right to host the 2017 Firefly International Convention in Taiwan. The firefly resurrection project was launched from the end of last year. Now the public can already be in Daan Forest Park. Watch the fireflies.

According to Professor Yang Pingshi, former dean of the National Taiwan University of Bioresources and Agriculture, Da'an Forest Park is the world's first capital. In cities where fireflies are successfully rehabilitated in densely populated areas, it is a very difficult project to reproduce fireflies.

In particular, the artificial lighting facilities have a great impact on fireflies, and Yiguang is one of the important promoters for the successful resurrection of fireflies in Daan Forest Park.

This time, Yiguang, responsible for the firefly eco-pool lighting equipment, designed a special wavelength LED street light for the firefly's retinal habits, protecting the fireflies from artificial lighting, and not affecting the firefly's retina development, so that the people can be in the city. The dream of seeing fireflies finally came true.

Plug In Series​ Diode

In the rectifier circuit; the use of diodes in series can increase the back pressure withstand value (usually the sum of the back pressure of all diodes, but it is best to use diodes of the same specification).
In the voltage stabilization circuit; the series connection of the diode is equal to the sum of the voltage stabilization value of the diode. The use of diodes in parallel is theoretically the sum of rated currents, but considering that it is impossible to be absolutely symmetrical, they can only be used below 80% of the total.

TVS transient suppressor diodes work in the same way as regulator diodes, but there are structural differences.The biggest difference is that the PN junction area composed of the general regulator diode is very small, it can withstand the reverse current is small.
