Description

A Multifunctional Solar LED Flashlight

technical field

The utility model relates to the technical field of multifunctional flashlights, in particular to a multifunctional solar LED flashlight.

Background technique

The flashlight is a commonly used portable mobile lighting tool. The traditional flashlight is composed of a shell, a reflector, a small incandescent lamp and a dry battery. Because of its simple design, the flashlight is easy to use and carry, and has become an indispensable part of people's daily life. One of the mobile lighting devices. Due to the high power consumption of incandescent bulbs and low luminous efficiency; and the limited capacity of dry batteries, the continuous use time is short. pollute. In order to solve the above problems, people have designed a rechargeable flashlight, which replaces the dry battery with a rechargeable battery and installs it in the lamp tube to supply power to the light bulb. The tail cover is connected to the rear end of the lamp tube to fix the battery. The tail cover is also provided with a charging plug To charge the rechargeable battery, the switch is set on the lamp tube. After connecting the light bulb and the battery, it is used to control the connection and disconnection of the light bulb and the battery, which is easy to use.

With the progress of society and the rapid development of high technology, rechargeable flashlights have appeared. Rechargeable flashlights are connected to normal AC power sources for charging, and the use of them is terminated by the power supply. At the same time, power resources are also in short supply, so they are in urgent need of improvement. Some solar flashlights Also pour into the market, but its function is single, can not make full use of resources, can only meet the basic requirement of people's lighting. As a commonly used high-efficiency, energy-saving and portable mobile lighting tool, a flashlight that uses high-brightness white LEDs instead of small incandescent lamps has been widely used in indoor and outdoor emergency lighting, field operations, exploration, etc. At the same time derived a rechargeable LED flashlight. The rechargeable LED flashlight needs to be connected to an external (110V/220V) AC power supply when charging.

The solar flashlight uses solar panels to convert solar energy into electric energy for the flashlight, and the solar battery stores the electric energy for use. But it also has the following problems: 1. The function is relatively single and cannot meet the needs of outdoor activities, especially in field operations, expeditions or long-distance travel, often because the latest information from the outside world cannot be obtained in time to make oneself live in an information-blocked space. 2. Since the shell of the grip part is cylindrical, it is not easy to install solar panels, or to open a special installation slot, but it will affect the overall appearance. 3. There is only one solar panel, the lighting area is relatively limited, the electric energy converted by solar energy is less, the conversion rate is also low, and it takes a long time to fully charge the battery. 4. The lighting lamp of the flashlight has only the front lighting LED light arranged at the position of the lamp head, which can only be used for long-distance lighting, and is not convenient for short-distance lighting.
