The invention discloses a lamp head component capable of adjusting a light projecting direction in a rotating mode. The lamp head component comprises an outer lamp head unit, an inner lamp head unit and a flexible pressing unit, wherein the outer lamp head unit comprises at least two electricity conducting pins; the inner lamp head unit is arranged in the outer lamp head unit in a rotatable mode;the flexible pressing unit is arranged in the outer lamp head unit in a movable mode so as to selectively position the inner lamp head unit relative to the outer lamp head unit or position the outer lamp head unit relative to the inner lamp head unit; and the flexible pressing unit is provided with a pressing element which can be selectively exposed outside the outer lamp head unit. Through the control of the flexible pressing unit, a hollow light-permeable lamp tube which is linked with the inner lamp head unit can drive a light-emitting component to rotate together, and the light projectingdirection of the light-emitting component can be easily adjusted, so that the aim of adjusting the light projecting direction in the rotating mode can be fulfilled.
Description
technical field [0001] The invention relates to a lamp cap assembly and a lighting lamp tube, in particular to a lamp cap assembly and a lighting lamp tube which can adjust the light projection direction by rotating. Background technique [0002] It is well known that with the improvement of living standards, lighting and lighting decorations are gradually paid attention to by the public. If suitable lighting decorations can be matched in indoor and outdoor decorations, lighting decorations not only have practical functions, but also have the function of beautifying the environment. At present, most people still use fluorescent tubes as the light source for lighting. [0003] However, in recent years, light-emitting diode (LED) technology has been growing and its application scope has increased, and it has frequently appeared in daily necessities around us. Power consumption, the heat energy generated by light-emitting diodes is small, and light-emitting diodes have the abo...
