LED flashlight

Abstract

The invention discloses an LED flashlight. The flashlight comprises a vertical lamp tube, a lighting lamp holder, a communicating lamp tube, a vertical lamp tube, a light reflection mechanism and a light attenuation mechanism, the bottom of the lighting lamp holder is fixedly connected with the top of the vertical lamp barrel; the communicating lamp tube is installed at the bottom of an inner cavity of the lighting lamp holder in a penetrating mode. The bottom of the vertical lamp tube is detachably connected with the top of the communicating lamp tube; the light reflection mechanism is arranged at the top of an inner cavity of the lighting lamp holder. The light attenuation mechanism is arranged at the bottom of an inner cavity of the lighting lamp holder. The LED flashlight adopts a scale type reflector design; the inclination angle of the internal reflector is directly changed by rotating the control piece on the outer side, so that the angle, namely the area of a light coverage area, of bulb light irradiated to the external environment is changed, and the scale type lamplight reflection mechanism can accelerate air flow in an inner cavity in the position of the flashlight lampholder in the angle changing process and conduct auxiliary heat dissipation on the lamp holder.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an LED flashlight. Background technique [0002] A flashlight is a hand-held electronic lighting tool, which generally includes a battery-powered bulb, a focusing reflector, and a handle-type housing for hand-held use. With the continuous development of science and technology, the flashlight has also made great progress. The use of LED bulbs as the light source of the flashlight has become very popular. The high brightness of the LED bulb makes the flashlight smaller in size, easy to carry, and consumes less power. Very obvious advantage. [0003] However, the general flashlight can only determine its illumination intensity and illumination range according to the wattage and fixed configuration of its bulb, and its irradiation light intensity and illumination range are all unchangeable, which has certain limitations in use. In order to solve the problem of the lighting range a...
