Problems solved by technology

At present, white light LEDs have begun to enter some application fields, and products such as emergency lights, flashlights, and flash lights have come out one after another. Both use traditional reflectors to adjust the beam to achieve the purpose of concentration or dispersion, but the adjustment range that can be achieved is very small, the effect is not good, and it will also affect the intensity of the beam; when using a lens to adjust, it is not only easy Abrasion affects lighting, and only one adjustment effect can be achieved with one lens, and the function is single

Abstract

The invention relates to a lamp, in particular to a multifunctional reflection-free LED lamp adjustable in light beam, which is adjustable in light beam within a large range and simple and convenient in use. The reflection-free LED lamp adjustable in light beam comprises a lamp shell (1), a lamp holder (2), a power supply device (3), a control device and a supporting device, wherein the power supply device (3) is arranged in the lamp shell (1). The control device is respectively connected with the lamp holder (2) and an adjusting bottom cover (4) which is rotatably connected to the bottom of the cylindrical lamp shell (1). The lamp holder (2) is in a plate shape and made of flexible materials, and can form an outward-convex or inward-concave curved surface under the control of the control device, and a plurality of LED lamps (5) are arranged on the lamp holder (2). The supporting device is arranged in the lamp shell (1) and used for limiting the motion direction of the control device. The reflection-free LED lamp adjustable in light beam has the advantages that luminance loss is avoided, lens adjustment effect can be achieved, and the lamp is wide in adjustment range, stable in structure, convenient in use and versatile.

Description

Technical field [0001] The invention relates to a lamp, specifically a non-reflective LED lamp with adjustable beam. Background technique [0002] In 1809, British chemist David invented the arc lamp, and mankind entered the era of using electric lighting. In 1906, Edison invented the household electric light bulb using tungsten filament as the filament. In the future, incandescent lamps, fluorescent lamps, energy-saving lamps, neon lamps and contemporary high-tech invented high-tech lamps have sprung up on the stage of lighting. LED lamps have also become an important member of them, and they are greatly convenient. People's production and life. [0003] In people’s daily life, most of the lamps are used for lighting and luminescence. Compared with the existing incandescent lamps, fluorescent lamps and energy-saving lamps, LED lamps are a kind of green environmental protection light source, which is a cold light source with low glare and no radiation. No harmful substances are ...
