Embodiment Construction

[0032] in Figure 1 to 3 The first embodiment of the flexible surface light source 10 is shown in FIG. The flexible surface light source 10 has a transparent covering layer 11. There is a light exit surface 12 at the transparent cover layer 11, and the light of the surface light source 10 exits at the light exit surface. The covering layer 11 is at least transparent to the light wave length spectrum or light wave length that should be emitted from the surface light source 10, for example, white light or light of a certain color.

[0033] The surface light source 10 has a reflective layer 13 with a reflective surface 14 on the side opposite to the covering layer 11. The reflective surface 14 faces the covering layer 11. No light can pass through the reflective layer 13 and leave. The light incident on the reflecting surface 14 is completely reflected.

[0034] A first scattering layer 15 is optionally attached to the cover layer 11 on the side opposite to the light exit surface ...

Abstract

The invention relates to a surface area light (10), in particular for use in a piece of clothing (30). The surface area light (10) according to the invention has a cover layer (11) having a light emission area (12). A reflection layer (13) having a reflection area (14) is arranged on the side opposite the cover layer (11). A first scattering layer (15) made of a textile material, preferably a textile fabric, directly adjoins the cover layer (11). The textile fabric can be connected to the cover layer in a laminar manner or can be in contact thereto. Light sources (16) are arranged at a distance from each other in a longitudinal direction L in one or more rows. The light sources (16) have a light emission side (17) which faces the reflection layer (13). A spacer means (19) secures a minimum distance between the light sources (16) and the reflection layer (13). The light emitted from the light sources (16) is reflected on the reflection layer (13) to the cover layer (11). The optical path within the surface area light (10) can thus be enlarged without enlarging the thickness of the surface area light (10) at a right angle to the light emission area (12).

Description

Technical field [0001] The present invention relates to a flexible surface light source, which is especially arranged for use in clothing. Furthermore, the present invention relates to clothing with such a surface light source, such as a jacket. The surface light source can also be used as an installable and removable element such as a back sign, a chest sign or an arm sign that can be connected to clothing, such as a jacket. In order to make a releasable connection, connecting devices such as buttons, Velcro etc. can be used. The surface light source can be used to improve the visibility of the person wearing the clothing and / or display information for other persons when used in the clothing, such as, for example, the feature mark of the action team, such as rescue personnel, security personnel or auxiliary personnel. Background technique [0002] US 8690385 B2 describes electronic textiles that function as light emitting. Here, the light-emitting diodes are arranged on a fle...
