Problems solved by technology
[0002] At present, the lighting distance of flashlights on the market is relatively short, which is not suitable for long-distance lighting application scenarios. Usually, in order to increase the lighting distance, traditional flashlights or searchlights will use stacked light sources, which will cause problems such as high power or large volume. It increases the weight, also increases the cost, and is not easy to carry, it is very inconvenient to carry during long-distance search

Embodiment Construction
[0017] In order to better describe the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0018] Such as figure 1 , 2 As shown, the present invention includes a flashlight body, a light source module, a light source controller 6 , a battery 7 and a button 8 . The light source module includes a laser generator 1, a transmissive phosphor sheet, a light shaping unit, and a focusing lens 5. The light beam emitted by the laser generator 1 is incident from one side of the transmissive phosphor sheet, and is excited by the phosphor powder therein. Fluorescence, and after being shaped by the light shaping unit, it emerges from the other side. The battery 7 supplies power to the light source controller 6, and the light source controller provides a stable current to the laser generator 1, and can adjust the luminous intensity and power of the laser generator 1.
[0019] The light shaping unit includes a ...

The invention belongs to the field of lighting equipment and relates to a variable-focus highlight illumination flashlight. The variable-focus highlight illumination flashlight comprises a flashlight body, a light source module, a light source controller 6, a battery 7 and a key 8; the light source module comprises a laser generator 1, a transmission type fluorescent powder sheet, a light shaping unit and a focusing lens 5; and light beams emitted by the laser generator 1 enter from one side of the transmission-type fluorescent powder sheet, are excited by fluorescent powder in the transmission-type fluorescent powder sheet to emit fluorescent light, and the fluorescent light is emitted from the other side after being shaped by the light shaping unit. According to the variable-focus highlight illumination flashlight of the invention, the laser generator is separated from a wavelength conversion device, and an excitation light source with higher power than that of traditional lighting devices such as an LED can be adopted, so that the luminous intensity of an emergent light beam generated by the wavelength conversion device is higher, and the problems of weight, portability, cost and the like caused by superposed light sources are avoided.
Description
technical field [0001] The invention belongs to the field of lighting equipment, and in particular relates to a variable-focus glare lighting flashlight. Background technique [0002] At present, the lighting distance of flashlights on the market is relatively short, which is not suitable for long-distance lighting application scenarios. Usually, in order to increase the lighting distance, traditional flashlights or searchlights will use stacked light sources, which will cause problems such as high power or large volume. It increases the weight, increases the cost, and is not easy to carry. It is very inconvenient to carry during long-distance search. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a variable-focus glare lighting flashlight, which is specifically achieved through the following technical solutions: [0004] A variable focus glare lighting flashlight, comprising a flashlight body, a...
