Short lifespan, it can break down within 2-3 years at most after a few months; More than 90% of civilian solar lights use second-hand batteries from electric buses in big cities.
2-3 days of rainy weather, the lights do not turn on or the brightness is insufficient; Putting the electricity that should be used to resist rainy days for the first 1-2 days makes the lights appear bright. However, if the weather is cloudy and rainy for more than 2 days, it becomes very dark, even staying on for 1-2 hours or not lighting up, making it impossible to use it as a main road.
Change brand, company name, and legal representative within 2-3 years without any after-sales service; Due to the inability to fulfill the "warranty service" commitment to customers, consumers have given a "negative review" of the industry.
At present, the market competition is fragmented, with no leader, simple assembly, and significant differences in product quality. Users (Party A) lack a sense of security, and intermediaries crave leading brands.
The Yuzhiyuan LED digital constant current source with a fixed power consumption of 0.0625W replaces the traditional 20% constant current source of LED, saving 20% electricity
Based on the forward light emission and reverse heating characteristics of LED, the heating power is turned off without the need for a heat sink, saving 50% electricity
Less people and less cars in the second half of the night, using digital dimming technology to reduce some brightness and save 10% electricity
1. The Yuzhiyuan LED digital constant current source with a fixed power consumption of 0.0625W replaces the traditional 20% constant current source of LED, saving 20% electricity 2. According to the forward light emission and reverse heating characteristics of LED, turning off the heating power does not require a heat sink and saves 50% electricity 3. Less people and less cars in the second half of the night, using digital dimming technology to reduce some brightness and save 10% electricity
On the basis of saving 80% of electricity, AI artificial intelligence digital power distribution technology can be used to better customize according to the requirements of rainy days and environmental brightness in various regions: 1. Either extend it to 5 times longer than conventional technology on rainy days 2. Either increase the brightness to 5 times, 3. Either reduce the system cost of solar street lights by 80% to achieve energy saving and cost saving 4. It is also possible to increase some brightness, extend some rainy days, and reduce some costs according to user needs, taking into account all factors.
1. The battery uses a brand new lithium iron phosphate battery with a deep cycle of 2000 times, which is 7 times the lifespan of lead-acid batteries 2. Software intelligent management of a lamp, saving electricity can make the battery and lamp last longer 3. Using high-quality electronic components and stable surface mount soldering processes 4. Using aluminum casing, durable and rust free 5. The sealing ring is waterproof to a depth of one meter and does not allow water vapor to enter 6. The lampshade is made of special materials that are more durable than car headlights, impact resistant, and do not change color. 7. All hardware brackets are welded using full welding process The design and materials used in every detail ensure a lifespan of over 15 years
