Description
Technical Field
[0001] This utility model relates to the field of lighting tools, specifically a flashlight. Background Technology
[0002] A flashlight is a handheld electronic lighting tool. The traditional structure consists of a battery-powered bulb and a focusing reflector, with a handle-type casing for holding. Depending on different usage needs, existing flashlight products have shown a wide variety of variations in appearance, performance, and functions.
[0003] Traditional dry-cell battery flashlights only use the front light for long-distance focused illumination and do not use the side light for short-distance floodlighting. Their limited functionality makes them inconvenient for people's needs for both focused long-distance illumination and floodlighting for short-distance illumination.
[0004] At the same time, even if existing technology can be used to arrange focused long-distance lighting and floodlight short-distance wide-range lighting in different directions on the flashlight, it is necessary to design the layout of two directions inside the flashlight, which is very difficult for production and assembly. In addition, the installation position of circuit components must also be considered, making it impossible to truly integrate the two functions of focused long-distance lighting and floodlight short-distance lighting into one product.
