Solar led light circuit for single cell lithium battery

I am professional embedded IoT product engineer. I have experience with circuit design and development. I can develop the circuit for you . I already have basic circuit ready. Drop me message to discuss more. Thank you

Hello there! My name is Muhammad Adeel, and I'm an experienced electrical engineer with a deep understanding of electrical engineering principles and the ability to apply them to solve complex problems. I have extensive knowledge in electronics, specifically in developing specialized circuits that are suitable for solar-powered applications. I have already worked on voltage regulators to convert VOLTAGES from 12v to 3.3, 3.7 volts. I believe that I would be the best fit for your project because of my expertise in electrical engineering and solar energy. Additionally, I have experience working on complex projects before so I'm sure that I can handle this one too. Plus, I'm a team player who is always willing to help others reach their goals so we can get this project done quickly and effectively. I'm confident that my skillset and experiences make me the perfect fit for this project and am excited to hear more about it! Please feel free to reach out with any other questions or concerns you may have.

My name is Bharathi I am a elactrical and Elactranics engineer and Elactranics designer and pcb designer you want solar panel led circuit for 3.7v single cell lithium batterie it's wery easy job for me so I do this project

hey my name is kishan . form electronic engineer. i can do this is project. i know pcb designing with altium designer

Hello there! I am Dharmesh, a Electronics and PCB Layout expert. I understand from your description that you are looking for someone with expertise in developing a specialized solar-powered circuit that is suitable for use with a single cell lithium battery. Specifically, you are looking for someone with experience in creating LED light circuits that require between 1-2W of power and have a 3.2V UV LED lamp with a 60mA current rating. I believe I am the perfect person for this project! With over 10 years of experience in electronics and PCB layout, I have the knowledge necessary to create a fully functional LED circuit that provides the necessary wattage to the LED lamp while operating at 3.7V voltage rating. Additionally, my end product should continue to function until the battery BMS cutoff point (2.8V), automatically turn on/off when exposed to sunlight, include an on/off manual switch as well as an auto-on/off function, and work without issue on full brightness without needing any battery charging from the solar panel directly. I would be delighted to assist you with developing your unique solar led light circuit! Please let me know if you would like me to discuss further or answer any additional questions

Hello! I am sure that I am able to develop your idea ? To ensure longer working li-ion, it's strongly recommend to include some circuit to safely charge battery. BMS is not able to regulate current going to battery. We can add photo resistor to detect day/night and potentiometer to fine tune detection threshold. Also it's important to calculate total power consumption, so lamp can operate in whole time with "night" condition at lower power or simply max power until BMS cutoffs. It's necessary to make buck boost LED driver to ensure that 3.2V LED will work at full power in low battery condition. In linear driver input voltage needs to higher with enough headroom than LED operating voltage and it's considerably less efficient. I believe that your project would be done in less than 3 days with rich features and great performance. It would be my first project on this platform and I want to give you the best quality possible in this simple project. If you have any questions please contact me.

Hi, This is Razak, I have been developing many solar-based products such as Solar inverters and Lighting systems even Cooling systems using high watts solar to low watts solar. For the above specification, I have already done a similar project and was put in an environment and worked without any failures. I hope this turns your attention to a project with me.
