FIELD: lighting engineering. SUBSTANCE: given supporting unit can be employed in lighting devices, specifically, in automobile stop lights. Supporting unit for light sources includes base 1, one or more lamp holders 2 for light sources 3. Each light source is made of two interjoined parts. First part is put on base 1 and second part has hole for light source and member 7 pressing printed circuit board 8 to light source 3. First part comes in the form of L-shaped member placed on base 1 and comprises support 9 carrying pressing member 7 and guide 10. Second part 5 has shape of hollow cylinder with external side boss12 which space 13 is open inwards of hollow cylinder and towards one of its butts. Another butt of hollow cylinder adjacent to open face of boss 12 carries lugs with end catches facing outwards. Parts of lamp holder 2 are so connected that guide 10 of first part assembled as one unit with edge section 18 of printed circuit board 8 is positioned in space 13 of side boss 12 of second part 5 on side of its open face. Printed circuit board 8 is fitted against member 7 pressing it to light source 3 located in hole of hollow cylinder of second part 5 that is mounted on support 9 of first part by means of lugs fixed in it with the help of its end catches. EFFECT: enhanced functional reliability of unit thanks to ensured contact of printed circuit board with light source, convenient assembly of unit. 15 cl, 6 dwg |
