Charging efficiency is good, also can be charged in the rain or when diffused light.
In addition, it can be installed in a wide range of areas in temperate destinations in cold climates in a wide operating temperature range (-20 ℃ - 60 ℃).
Sunlight, Inc. - The Solar LED Solution CompanySunlight, Inc. - The Solar LED Solution Company
And utilizing solar energy for natural, because it does not use a conventional battery, there is almost no regular replacement deterioration due to charging and discharging, such as a battery needed.
The material is mainly activated carbon, I can environmentally friendly.
Sunlight, Inc. - The Solar LED Solution CompanySunlight, Inc. - The Solar LED Solution Company
The combination of the charge and discharge times 100,000 times or more electric double-layer capacitor and a light emitting diode (LED), and realize a system of long life. It has a life of several tens of thousand hours, for very power-saving, including the signal, it is used in a variety of applications.

Charging and discharging times of the electric double layer capacitor there is more than 10 million times, I've been with the system to repeat the charge and discharge every day. The rain from the goodness of the efficiency of charge and discharge, you can cover the night of the quantity of electricity in charge of under cloudy weather.

 Automatic control the brightness, lighting time
It employs a "semiconductor photosensor" in order to detect the ambient brightness. Photo sensor does not have be false positives in such infrared you do not feel the human eye because it uses a sensor close to the (light wavelength sensitivity felt by the human eye) visibility. It also does not include the environmental destruction substances such as cadmium.
In addition, automatic lights in the following environment illuminance is about 50 to 100 lux (immediately after evening), it automatically turns off when it comes to about 50 lux (immediately after sunrise).

Medium save the storage media

Electrical (storage medium) to mainly capacitor (aka"electric double layer capacitor" I have adopted). The material does not contain a "lead" and "cadmium" which is environment-depleting substances in the activated carbon. In addition, since that can be charged and discharged 100,000 times, I can say that does not require battery replacement.


LED

Without fear of the ball out as incandescent lamps and fluorescent lamps, life also several tens of times of fluorescent lamps, and 3 to 5 times of HID lamp (high intensity discharge lamps), lights up several tens of thousand hours. Also, as in the fluorescent lamp, are not included in environmental-depleting substances such as mercury.

 Supports all-weather
(depending on the installation conditions)

To those of the solar cells

small size, the "amorphous silicon solar cells", also to those of medium and large, it has adopted a single-crystal silicon solar cells mainly. Amorphous silicon solar cells, the light efficiency of changing to electric (conversion efficiency) is slightly degraded, there is a characteristic, such as can be taken out electricity in the shade, depending on the installation and use environment, we are appropriately selected the solar cells.

Medium save the storage

electricity I am adopted (storage medium) to mainly capacitor (also known as "electric double layer capacitor").Capacitor, as compared to a conventional battery of, less variation in performance due to temperature, use range from low to high temperatures (-20 ℃ 〜 60 ℃) is also widely, can be installed in a wide range of areas.

LED

temperature is lowered. LED, by contrast, does not undergo little affected by temperature, used in the cold land is possible. (Up to -80 ℃, it does not change very much.)


 Full and rechargeable sunshine conditions

During the day is required to charge possible environment for more than 10 hours at 20 000 lux. (Equivalent at the time of the summer of cloudy weather.) In the above the following sunshine conditions, or shorten the lighting time, in extreme cases may not light up.
- direct illumination during fine weather but is more than 100 000 lux, is why that illuminance only obtained about one of the light energy of about 5 thousand lux and 20 minutes in the rain.

 The electric double layer capacitor?

Sunlight, Inc. - The Solar LED Solution Company
In one of the electric double layer capacitor (capacitor) is medium storing the electricity, is made up of the electrolyte solution and a pair of activated carbon electrodes. Charge, because it does not involve chemical reactions during discharge, almost no degradation of the electrode life is extremely long and can be used for a long time.
Key Features
  • her rechargeable battery can be charged and discharged.
  • You can charge and discharge of large capacity than normal capacitor.
  • Electrode using activated carbon, in the solution of the dark salt in the electrolyte, lead, because it does not use the heavy metals such as cadmium, does not give an adverse effect on the environment.

 Solar LED lighting, and display board
Using the solar capacitor power, it is a system that turns on the LED lighting and LED display plate or the like. Daytime, and storage of electrical energy that was generated by the solar panels to the capacitor, the night automatic lighting by a photo sensor. When fully charged, I will light for 15 hours.

  • Battery replacement is not required in the electric double layer capacitor adoption.
  • You can use the LED as the light source does not have to worry about the ball out.
  • Since solar power does not require a power supply works, I will run even in the case of a disaster such as a power outage.
  • It does not adversely affect the environment without the use of harmful heavy metals in the storage unit.

  • There is no worry of burn out because the light source is using the LED.
  • Power construction and wiring does not choose the unnecessary and location because it is solar power.
  • Battery replacement is not required in the electric double layer capacitor adoption.
