New Solar-powered Sensor Lighting for Challenging Outdoor Environments

Upgrade to the LC-2000 series used for tsunami evacuation towers, etc.

Optex Co., Ltd. (Headquarters: Otsu City, Shiga Prefecture, President & CEO: Toru Kamimura, hereinafter “Optex”) has launched the LC-2000LU outdoor sensor lighting and LC-SBU solar battery unit (hereinafter “LC-2000LU”) on January 18, 2023.

Coming 10 years after its predecessor—the LC-2000—was first brought to market, the LC-2000LU includes greatly enhanced specifications with the addition of expandability for the solar battery unit and improved resistance to salt damage, among other changes.

Background of the development

The LC-2000 as released in 2013 utilized an infrared motion sensor—a specialty of Optex—to improve power consumption efficiency. This product offers compact size and light weight that have been favorably reviewed for their ability to resolve some of the cost and installation issues that face conventional solar lighting. It is being used in a variety of applications, such as for tsunami evacuation towers and for parking lots that lack power sources.

The LC-2000LU has been completely redeveloped with the aim of improving environmental resistance and maintainability.

Differences between general solar lighting and solar-powered sensor lighting

With general solar lighting, the solar panels and batteries are large in order to keep lights on throughout the night.
In contrast, the compact and lightweight LC-2000LU can be installed at about one third* of the cost.

Main specification improvements

The LC-2000LU can be expanded with up to three solar battery units, which will ensure sufficient energy storage capacity even when used at busy roadside stores or on suburban school routes.
It is also designed to be highly salt-resistant, which makes it suitable for installation in areas close to the sea.

Assumed usage scenario and CO2 emission reduction

It is especially suitable for school routes and parking lots where power sources are not available. In addition, there are many locations where outdoor lighting has not yet been converted to LED, so switching to LC-2000LU can help to efficiently reduce CO2 emissions.
