Embodiment Construction

[0034] The invention discloses a portable lighting device, such as Figure 1~3 As shown, it is a structural schematic diagram of the first embodiment of the present invention, including a luminous body 3 and a transparent thin plate 2 installed on the support frame 1, and the three sides of the transparent thin plate 2 are fixed by the support frame 1, of course, also Only one side, two sides, or even four sides of the transparent thin plate 2 can be fixed.

[0035] The transparent thin plate 2 of the present invention can be made of polyacrylate (PMMA) material, and the high light transmittance of the polyacrylate light-guiding material can be used to avoid light loss during transmission. Moreover, the geometric shape of the transparent thin plate 2 is not limited to a rectangle, it can also be other shapes, such as circle, triangle, trapezoid and so on. In addition, preferably, at least one side of the transparent thin plate 2 of the present invention is connected to the lu...
