FIELD: lighting.
SUBSTANCE: invention relates to a circuit board in field of lighting. Circuit board has a dielectric layer (140A/B, 240A/B, 340, 440, 340B, 440B) on top and/or bottom thereof. Circuit board also has core layer (110, 210, 310, 410) and at least one conductive layer (130A/B, 132A/B, 230A/B, 232A/B, 330, 430), positioned on a first side of core layer (110, 210, 310, 410). Outer dielectric layer (140A/B, 240A/B, 340, 440, 340B, 440B) is provided atop an outermost of at least one conductive layer (130A/B, 132A/B, 230A/B, 232A/B, 330, 430). Dielectric layer (140A/B, 240A/B, 340, 440, 340B, 440B) includes a plurality of openings (334A, 336A, 445A) that provide access to at least one of connection pads and through holes, that are in electrical contact with one or more of conductive layers (130A/B, 132A/B, 230A/B, 232A/B, 330, 430).
EFFECT: technical result is creation of fire-resistant and/or shock resistant circuit boards in field of lighting, to solve problem of safety and/or to comply with safety standards, related to lighting fixtures.
