Description

Technical Field

[0002] Portable lamps are a commonly used lighting tool, suitable for outdoor activities, emergency rescue, night work and other occasions. At present, the common portable lamps on the market mainly include flashlights, headlamps, camping lights, etc., which have brought great convenience and assistance to people's lives. Whether it is a dark environment with insufficient light during the day or a dark night, portable lamps provide a good lighting solution. With people's pursuit of high-quality life, multi-functional portable lamps have emerged. For example, lamps are compatible with multiple LED lamp beads, multiple brightness, front main lights, side auxiliary lights, etc. At the same time, some special lamps have also appeared, such as corner flashlights and corner headlights. The novelty and convenience of the corner function bring great practical value to users. However, after the existing corner lamps are turned, either the space they occupy becomes larger or the shape and size of the original materials are completely changed; in addition, the existing corner directions are single, and the final shape of the corner only achieves corner light emission between the front light-emitting direction and the 90° angle of the corner, while the corner light-emitting direction is limited to the angle between 0-90°. This limits the original advantage of the corner due to factors such as increased volume or changes in shape and size and a small light-emitting range, thereby weakening the advantage of the corner function.
