Description

【Technical field】 [0001] The invention relates to a portable lighting tool, in particular to an LED torch. 【Background technique】 [0002] Flashlight is a common lighting tool in people's daily life. The first-generation torch is the first-generation torch, commonly known as "old-fashioned torch", with the shell of iron sheet plated on the surface. The bulb generally uses a tungsten filament incandescent bulb, which has low luminous efficiency, short service life, and is easy to be burned out. The battery uses a large alkaline battery, which has a large volume but low battery life. The shell of the flashlight is made of iron plated on the surface, which is light in weight but simple in craftsmanship. The flashlight with aluminum alloy as the shell material is the second generation flashlight, which has a new breakthrough in both performance and appearance. A typical representative of the second-generation torch is the use of krypton bulbs + alkaline batteries, with longer...
