Abstract

The invention relates to a portable lamp which comprises a shell, a lamp holder arranged on the shell, as well as a spotlighting reflector, a floodlighting reflector, a light source and a rotating shaft which are arranged in the lamp holder, where the rotating shaft is used for mounting the light source and driving the light source to rotate, two ends of the spotlighting reflector are open, the spotlighting reflector is positioned on the lateral wall of an inner cavity of the lamp holder; the floodlighting reflector is positioned at the bottom of the inner cavity of the lamp holder; two ends of the rotating shaft are positioned on the lateral wall of the inner cavity of the lamp holder, and at least one end of the rotating shaft penetrates the lateral wall of the inner cavity of the lamp holder; and the light source is positioned below the lower-end opening of the spotlighting reflector. The portable lamp achieves the switching between the spotlighting function and the floodlighting function by rotating the light source to match the spotlighting reflector and the floodlight reflector, considers both spotlighting and floodlighting, is convenient for using and has good illumination effect.

Description

Technical field [0001] The present invention relates to the field of portable lamps, and more specifically, to a portable lamp that can realize the functions of concentrating and flooding lighting. Background technique [0002] The portable lamps in the prior art, especially the portable lamps using LED light sources, have a single lighting function and cannot take into account spotlighting and floodlighting at the same time. This will bring a lot of inconvenience to use. For example, when walking at night, you need to have Illumination with wide illuminance at close range also needs spotlight that can illuminate far away. Existing portable lamps with flooding and condensing functions generally adopt a defocusing method or a reflector frosting method to achieve the effects of flooding and condensing. Defocused lamps often have uneven illumination, dark spots and black holes appear in the light spots, and the way the reflector is frosted will greatly reduce the lighting effect of...
