The invention relates to the field of home decoration or tooling, and particularly discloses a lamp band structure adjustable in
irradiation angle and a lamp band mounting structure. The lamp band structure adjustable in
irradiation angle is characterized in that a strip-shaped lamp housing, a rotating sleeve, rotating sleeve clamping parts and vertical pillars are arranged for a strip-shaped
light source plate in the lamp band structure, on one hand, light rays emitted from the strip-shaped
light source plate are adjusted in
irradiation angle, so that more light rays can project onto the ceiling, the ground surface, the wall surface and the room, the environment embellishing effect of the lamp band is improved to a lighting effect on the overall room, and the conventional direct lighting method is changed; on the other hand, the shading effect of a light trough environment on the light rays is reduced,
light energy consumption in the inner area of the light trough is reduced, and the purpose of saving the
electric energy is achieved; meanwhile, as the
light source of the lamp band is hidden in the light trough, not only is the lighting effect improved, but also the light rays emitted from the lamp band light source are prevented from being incident on human eyes directly, the problem that the conventional lighting lamp is high in brightness but dazzling is solved, and the life and work of people is facilitated.
