Product Description

Features:1.12 hours time light, convenient for transportation;2. Can drive single lamp beads to parallel lamp string;3. Charging current can reach ≤0.5A;4. White lamp beads around 10mA;5. White lamp beads are used by default;.6. Can be set to constant light or flashing light, the default is long light, short circuit S1 is flashing;7. When set to flash mode, the flash frequency is about 2Hz;8. The overall low power consumption design of the circuit board, and the lighting time is long;9. Single-cell lithium iron 3.2V, single-cell lithium battery 3. 7V, three strings of nickel-metal hydride can be used (requires built-in battery charge and discharge protection board);10. With light control function, no photoresistor, realized by monitoring the solar voltage: charging during the day and automatically lighting at night;11. Circuit board volume size: length 20mm * width 15mm.

Applicable occasions:1. Solar single and double-sided road studs, solar ship warning lights, solar outline lights, solar navigation lights;2. Home solar landscape lights, solar mason light jars, solar lawn lights, solar Christmas lights, solar starry solar string lights, etc., charging and light-sensitive switches and flashing lights. The circuit board has the function of a lamp driver, and the white LED lamp beads can be used directly. If you use lamp beads of other colors, you need to adjust the drive current. The drive current of the circuit board cannot exceed 20mA, which will damage the circuit board.

Electrical parameters:Solar panel voltage: about 5VSolar panel current: Determined according to the use environment, the solar charging current cannot exceed 500mABattery specifications: single-cell lithium iron, single-cell lithium battery, three strings of nickel-metal hydride (battery needs built-in protection board to prevent overcharge and overdischarge)Battery capacity: Determine according to the use environmentBattery discharge current: the use of white light is about 10mA, and the discharge current cannot exceed 20mAFlashing frequency: when set to flashing, the flashing frequency is about 2Hz (other frequencies can be customized)Important note: The actual voltage of the solar panel and the actual voltage of the battery cannot exceed 6V, otherwise the circuit board will be damaged !!

Lamp beads requirements:The circuit board uses white lamp beads or lamp strings by default. When using lamp strings, the lamp beads built in the lamp string are connected in parallel. If you use lamp beads of other colors, the battery discharge current may increase. The lamp bead is directly connected to the circuit board without the need for current limiting resistance. In batches, you can customize the circuit board to use other colors of lamp beads, or adjust the parameters yourself.When the circuit board is set to the long light mode, it can be connected to the LED lamp beads of the built-in chip !!!

Battery discharge current adjustment:When the battery voltage and the color of the lamp beads are fixed, the driving current of the lamp beads is determined by the resistor R3. The default resistance value is 33 ohms. When the battery voltage is 3.7V and the white lamp is used, the The drive current is about 10mA. When using other color lamp beads, you can obtain the discharge current you need by changing the resistance value, increase the resistance value and reduce the discharge current, reduce the resistance value and increase the discharge current. The driving current of the lamp bead needs to be controlled at 20mAInside, exceeding this current will damage the circuit board.

Welding requirements:The circuit board uses a large-scale integrated circuit chip, the chip is sensitive to static electricity, and anti-static measures need to be taken during soldering, otherwise the circuit board will be damaged;Light control function:The circuit board automatically controls the lighting and extinction by detecting the voltage level of the solar cell panel. The whole process does not require manual intervention to achieve the purpose of charging during the day and automatically lighting at night. The voltage threshold of the light control is controlled by the single chip microcomputer, and the light control threshold can be customized by adjusting the program to achieve the specified lightThe purpose of the next light.

Timing function:

The traditional road studs do not have the function of turning on the lights regularly. After they are assembled, they will be installed in the carton. The lights will turn on until the battery is exhausted. The customer cannot use the road studs immediately after receiving the road studs. normal work. If stored for a long time, the rechargeable battery will be damaged in a short time when the battery is exhausted. Because the road stud is a closed product, the battery cannot be replaced, resulting in the entire product being scrapped.

The road stud with light-up timing function will light up according to the time set by the program after packing, and the lamp bead will go out after the time, so as to achieve the purpose of saving power and protecting the battery.

The program running on this circuit board defaults to about 12 hours. It starts counting when the light is on, and turns off after about 12 hours. The timing process is controlled by the single-chip microcomputer. The timing can be changed by modifying the program in batches to reach the lighting time of the lamp. The purpose of customization.
