How to charge the electric soul searchlight DH-006

First of all, searchlights are prone to problems:

1, short for [collapse] when the light bulb doesn't work.

2. The 2.LED bulb is on, but the power indicator on the handle is not on.

3. The 3.LED beads are bright, but the brightness is not up to the requirements.

4, charging can't charge

Second, the light bulb is not bright for the following reasons:

A-The battery is dead [the scheme is to charge the battery, and the battery voltage is 14.8V after the BAD305 portable explosion-proof searchlight is fully charged, which is16.8V]]

B-bad battery [the battery is replaced in the scheme, and the battery of BAD305 portable explosion-proof searchlight is 18650, 14.8V2000mA battery pack].

C-LED bulb is broken [LED is replaced in the scheme, and the bulb of BAD305 portable explosion-proof searchlight is Ke Rui Q5 white high-power LED, with a plate diameter of 20* 1mm].

D-The intelligent driving board is broken [Solution] To replace the intelligent driving board, only Huarong explosion-proof and Yueqing Weichuang photos can be replaced.

The E button on the handle is not in good contact or the connecting wire inside the lamp is broken.

Third, the LED bulb is on but the power indicator on the handle is not on, for the following reasons:

A-The power indicator lamp is broken [replacing the indicator lamp will not affect the use of the lamp]

B-The drive board is damaged, and there is no 5V output [Scheme of replacing the drive board]

D-disconnection or virtual welding of the connecting line from the driving board to the power indicator lamp [scheme connecting line, welding line joint]

The reason why the LED beads are bright but the brightness can't meet the requirements:

A-LED lamp bead aging [lamp bead replacement scheme]

B-The high-frequency inductance of the drive module is poor or the output voltage and current are small [Scheme of replacing the drive board]

C-Huarong BAD305 portable explosion-proof searchlight has no large current output when the orange light is on, so it is normal that the brightness of the light is not high at this time [to prolong the lighting time].

Fourth, the reason why charging can't be charged:

A-When the charger is plugged in, the green light is on when there is no load, and the red light and green light of the portable lamp are off. The reasons for the failure are as follows.

1, battery short circuit,

2. The charging port is short-circuited.

3. The driving board is short-circuited,

4. The charger is broken

B-The charger is plugged in, and the green light will not light when it is empty [Scheme for replacing the charger]

C-the charger is plugged into the load, and the red light is on 10 hour, but the green light is not turned. The reasons for failure are as follows

1, battery failure,

2. The battery is short-circuited,

3. The charger has no current output or low output voltage.
