FIELD: lighting engineering. SUBSTANCE: invention can be used in the capacity of indicating lighting device, in particular, automobile stop lamp. Lighting unit comprises elongated body, diffuser connected to body and demonstrating various light zones and/or optical properties, flexible printed circuit board and light sources with lamp holders placed into reflector. Light sources with lamp holders and flexible printed circuit board are located on detachable base installed in body and coming in the form of elongated part including three elements. First element has U-shaped section with closed butts, second and third elements have L-shaped cross-section. Second and third elements are so positioned with reference to first element that their angles are directed outwards, first components of second and third elements are connected correspondingly to proper butt of first element and second components of second and third elements are so connected to one of elongated sides of first element that their adjoining butts face one another. On outside of second components there are formed cutouts which carry fixing elements. Guides carrying stopping teeth formed on outer side of each guide are located on opposite elongated side of first element. Body has location seat for base which is positioned in body and is fixed in it with stopping tooth of each guide and fixing elements. EFFECT: improved maintainability of lighting unit thanks to easy access to light sources and printed circuit board. 13 cl, 4 dwg |
