Abstract (en)
[origin: EP3023687A1] A lamp utilizing bar-shaped light source with unsafe voltage comprises a non-isolated power supply, a bar-shaped solid light source (22), and a housing (1) for fixing the bar-shaped solid light source. For a bar-shaped LED light source with an insulating substrate, the distance between a circuit for light source and the edge around the insulating substrate is larger than or equal to the creepage distance defined in safety regulation during manufacturing. For a bar-shaped LED light source with a non-insulating substrate, an insulation spacer (4) is disposed between the light source and the housing, so that the distance between the light source and two sides of the insulation space is larger than or equal to the creepage distance defined in safety regulation. Therefore, the insulativity of the lamp is ensured. By adopting the manners of pressing the bar-shaped solid light source to cross the creepage distance and fixing its one or more ends to the housing, or by adopting a C-shaped fixing manner, the bar-shaped solid light source is fixed to the housing, thereby the security risk caused by falling of the bar-shaped solid light source from the housing or the insulation space can be avoided.
