Embodiment Construction

[0055] figure 1 Shown is a daylight torch 1 for inspecting painted surfaces, in particular in the context of motor vehicle restoration work. The flashlight 1 has a head part 2 , a handle part 3 and, below the end of the handle part 3 , a releasably fastened accumulator 4 , in particular a lithium-ion accumulator. On its front side, the head part 2 has a light outlet 5 through which a light beam 6 can exit. A light 7 is arranged in the head part 2 in order to generate the light beam 6 . exist figure 1 In the figure, the head part 2 is shown partially cut away in the region of the light outlet 5 in order to show at least a part of the illuminant 7 .

[0056] Arranged on the rear side of the head part 2 is an operating element 8 by means of which the light intensity of the generated light beam 6 can be adjusted, for example, within a range of 50% to 100% of the maximum light intensity. On the side facing away from the operating element 8 and below the head 2 there is arranged...

Abstract

The invention relates to a daylight hand-lamp (1) for checking painted surfaces, in particular in the field of paint repair work on motor vehicles. The light spectrum is formed homogenously such thatat a distance of between 30 cm +/- 0,5 cm in a spectral range having a wavelength of 400 bis 700 nm, a daylight deviation average value in a central area and an inner periphery is less than 20%, or the average value of a spectral stability factor is less than 10% with respect to the beam center in the central area and inner periphery.

Description

technical field [0001] The invention relates to a daylight torch for inspecting painted surfaces, in particular in the field of paint restoration work on motor vehicles, wherein the daylight torch has a luminous body, by means of which a light beam can be generated with a sunlight-like light beam Spectrum and specular intensity. Background technique [0002] Visual inspection of painted surfaces is required during a range of painting jobs. This is especially true in touch-up paint of motor vehicles. It is therefore necessary to visually color-balance the freshly painted area with the original surface area, since color deviations can occur in practice despite detailed mixing regulations for pigmented paints in the paint industry. Additionally, prior to the painting process, a color chart, swatch, or contrast board is often visually compared to the already painted surface in order to determine the correct shade for repainting. [0003] In addition to checking the tone, visu...
