Light source and lamp obtained through same

The invention relates to a light source and a lamp obtained through the same. The light source is a graphene quantum tube luminophor. The lamp comprises a shell body, a cover body and a driving power source, wherein the cover body and the driving power source are connected with the shell body. The light source is installed inside the shell body. The light source adopts the graphene quantum tube luminophor, has superconductivity and high heat conductivity, can be rapidly started at a low temperature, is accurate in color temperature control and good in vibration resistance, can be processed into various shapes, such as a straight tube shape, an L shape, a U shape, a ring shape and the like easily and is high in plasticity. The lamp is simple in structure, reasonable in design, low in cost, good in illumination, low in output current and power consumption, good in sealing performance and long in service life; the power of the lamp can be made to be larger; and the lamp can be widely used for advertising lamp bo
