摘要
随着户外露营活动的兴起，兼具功能性与便捷性的露营灯成为户外装备的重要组成部分。传统露营灯多采用单一光源与固定亮度设计，难以满足不同场景下的照明需求，且操作方式繁琐，灵活性不足。
基于 STM32F103C8T6 单片机的双色露营灯设计，整合了 3 个独立按键、两条彩色灯带及驱动电路，实现了露营灯的灵活调光与双色切换功能。系统核心功能包括：通过 3 个按键分别控制两条灯带的开关、亮度调节（支持多级亮度渐变）及颜色切换（如白光与暖光的单独点亮或混合模式）；按键操作采用长按与短按组合逻辑，短按切换灯带工作状态，长按实现亮度连续调节，操作直观便捷；STM32F103C8T6 单片机通过 PWM 脉冲宽度调制技术精确控制灯带亮度，确保调光过程平滑无频闪，适应露营时的阅读、氛围营造等不同需求
该设计的实现，有效提升了露营灯的使用灵活性与场景适配性，通过简洁的按键操作即可完成多模式切换，避免了传统露营灯功能单一的局限。同时，STM32 系列单片机的低功耗特性延长了露营灯的续航时间，为户外使用提供了可靠保障，对提升户外露营体验具有实际应用价值。

ABSTRACT
With the rise of outdoor camping activities, camping lamps that combine functionality and convenience have become an important part of outdoor equipment. Traditional camping lamps mostly adopt a single light source and fixed brightness design, which are difficult to meet the lighting needs in different scenarios, and their operation methods are cumbersome with insufficient flexibility.
The design of a two-color camping lamp based on the STM32F103C8T6 single-chip microcomputer integrates 3 independent buttons, two color light strips and a driving circuit, realizing flexible dimming and two-color switching functions of the camping lamp. The core functions of the system include: 3 buttons respectively control the on/off, brightness adjustment (supporting multi-level brightness gradient) and color switching (such as separate lighting or mixed mode of white light and warm light) of the two light strips; the button operation adopts a combination logic of long press and short press, where short press switches the working state of the light strips, and long press realizes continuous brightness adjustment, making the operation intuitive and convenient; the STM32F103C8T6 single-chip microcomputer precisely controls the brightness of the light strips through PWM (Pulse Width Modulation) technology, ensuring a smooth and flicker-free dimming process, which adapts to different needs such as reading and atmosphere creation during camping.
The realization of this design effectively improves the flexibility and scenario adaptability of the camping lamp. Multi-mode switching can be completed through simple button operations, avoiding the limitation of single function of traditional camping lamps. At the same time, the low-power consumption characteristic of STM32 series single-chip microcomputers extends the battery life of the camping lamp, providing a reliable guarantee for outdoor use, and has practical application value for enhancing the outdoor camping experience.
