A lamp utilizing bar-shaped light sources with unsafe voltage comprises a non-isolated power supply, bar-shaped solid light sources (22), and a casing (1) for fixing the bar-shaped solid light sources. For bar-shaped insulating substrate LED light sources, 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 bar-shaped non-insulating substrate LED light sources, an insulating blanket (4) is disposed between the light source and the casing, so that the distance between the light source and two sides of the insulating blanket 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 sources, crossing the creepage distance, and fixing to the casing with one end or multiple ends, or a C-shaped fixing manner, the bar-shaped solid light sources are fixed to the casing, thereby the security risk caused by falling of the bar-shaped solid light sources from the casing or the insulating blanket can be avoided. |
