PROJECT CONTEXT
Solar power has appeared as a sustainable and efficient energy source, having widespread applications in our daily lives. One especially illuminating aspect of solar technology is its application in lighting solutions. Collecting light energy through solar panels during the day and converting solar energy into electrical energy at night has been used in some places.
Rural Areas Outdoor Lighting:
Rural areas are very suitable for the use of solar lights. Some rural areas have rough environmental conditions and complex terrain conditions, making it difficult to lay cables. Even if it is easy to lay, the cost of municipal circuit lights is very high according to the overall budget. It is more likely that the price of using municipal circuit lights will exceed that of using solar street lights. In addition, solar street lights are also simple to install, have a long service life, and require no maintenance within a long time. In rural areas, the roads are narrow, the height of the street light poles is low, and the brightness requirements of the LED light source are low, so solar lights are suitable for use in rural areas.
City Outdoor Lighting:
Solar-powered outdoor lighting has become common in residential areas, parks, and pathways. These lights offer a cost-effective and energy-efficient alternative to traditional outdoor lighting systems. This not only reduces electricity consumption but also enhances safety in public spaces.
Solar-Powered Indoor Lighting:
Houses in rural areas are primarily single-family, and each house has a large backyard. When people walk around in their backyards at night, having a light will bring great convenience. Compared with ordinary electric light sources, using solar lights will save many electricity bills in a year, and the solar lights will turn on and off automatically, which is very worry-free.
City homeowners and businesses are increasingly adopting solar-powered LED lighting systems. These systems utilize solar panels installed on rooftops or windows to collect and transfer electricity stored in batteries at night. This approach reduces reliance on grid power, lowers electricity bills, and decreases the overall carbon footprint.
Emergency Lighting:
Solar power plays a vital role in emergency lighting solutions. Solar-powered lanterns and flashlights provide reliable illumination during power outages or in distant areas without access to traditional power sources. These devices often have built-in solar panels for recharging, ensuring a consistent and sustainable light source in urgent situations.
Solar-Powered Devices and Accessories:
Solar power combines various daily devices and accessories, providing convenient and eco-friendly solutions: solar-powered phone chargers, backpacks with built-in solar panels, and even solar-powered watches. In particular, accessories like solar-powered light lanyards combine functionality and fashion, using solar energy to illuminate LED lights for practical and aesthetic purposes.
The concept of the Luminous Layard is to add charm to the wearer and more safety in a dark environment by utilizing solar power.
Walking at night requires people to worry about how lights up the path and how to warn people or motor vehicles coming the opposite way. In addition to wearing reflective gear, people could wear light accessories for a better alarm effect, especially when vehicles approaching from some angle that can not illuminate the reflective gear.
Incorporating solar power into daily lighting applications marks a significant stride towards a more sustainable and energy-efficient future. Solar-powered lighting solutions offer practical benefits and a reduced environmental impact from outdoor environments to indoor spaces and personal accessories. As technology advances, the widespread adoption of solar-powered lighting is expected to play a vital role in creating a brighter and more sustainable world.

NEXT STEP
The reason for choosing a lanyard is to add light to some accessories that people constantly use in daily life, but to achieve a safety effect, applying it to a big accessory like a bag or scarf will better realize it. Alternatively, the design of the lanyard could be beyond looking like a necklace. There are many possibilities. Besides, the circuit for collecting solar power should be hidden smartly and comfortably.
