Description

Technical Field

[0001] This utility model relates to the field of alarm clock technology, and in particular to an LED display alarm clock. Background Technology

[0002] An alarm clock is a clock with an alarm function, which not only indicates the time but also emits an audible or other signal at a predetermined time. Common types include analog alarm clocks and digital alarm clocks. Digital alarm clocks are increasingly favored for their intuitiveness, convenience, and accuracy. Existing digital alarm clocks generally include a control circuit and an LCD screen. The alarm is set and the time is adjusted via buttons on the control circuit. Most current digital alarm clocks connect to mains power via an adapter. Alarm clocks are typically placed on a desk, but due to limited desk space, the adapter and power cord take up space and easily clutter the desk. Furthermore, carrying the alarm clock and adapter when traveling is inconvenient. Some are battery-powered, but battery power has the disadvantage of short lifespan, with batteries typically running out in less than a month, affecting the alarm clock's usability. Existing digital alarm clocks have complex structures, and their displays, mostly LCD screens, are often difficult to see in low light or at an angle. Moreover, their manufacturing and operating costs are high, necessitating improvements to meet people's needs.

[0003] Therefore, developing an LED display alarm clock that is simple in structure, easy to manufacture, energy-saving, environmentally friendly, low in cost, provides a good user experience, and can be powered by batteries is a problem that urgently needs to be solved by technical personnel in this field.

[0004] This invention features an automatic light-sensing function, where the brightness of the time display increases according to the ambient light and dims in low light conditions, while still allowing the time display to be clearly seen and saving energy by preventing the battery from operating at its highest output. Additionally, the brightness can be adjusted using the function buttons on the back to avoid glare at night or in dark environments, resulting in excellent energy-saving performance.
