PURPOSE: A lamp is provided to achieve an improved efficiency by forming a reflection protrusion to prevent interference of light generated between light radiation tubes when the lamp is turned on. CONSTITUTION: A lamp(10) comprises two vacuum tubes(12,13,14,15); an upper case(18) and a lower case(20) supporting the vacuum tubes; a stabilizer(16) for rectifying an input AC power, converting the power into an oscillation power for driving the lamp and feeding the power to the filaments of vacuum tubes; a base(22) arranged at the lower end of the lower case; and a reflection protrusion(24) protruded from the upper center of the upper case so as to radiate to the outside the light which is offset by the mutual interference of vacuum tubes when the lamp is turned on. |
