This design is an enclosure for a DIY LED torch.
Components:
* 2000 mAh LiPo battery
* USB LiPo charger module with protection
* Two 3 mm LED's (red & green)
* 10w LED chip mounted on a 40x40 heat-sink with 12v fan
* Voltage boost module
* Switch
* M3 screws
Although the LED chip is a 10 watt; it 's running with 5 watts only due to limitation in the current supplied by the USB charging module. The voltage booster is used to boost the voltage of the LiPo battery from around 3.7v to 10v for the LED chip and heatsink fan.
All the modules can be found cheap from international suppliers.
