Abstract: The present disclosure provides a combined vaccine against human respiratory syncytial virus (RSV) infection and a method thereof for inducing immune response. The combined vaccine includes; a first composition including an immunologically effective dosage of a replication-deficient human adenovirus type 26 vector contains a nucleotide encoding an antigenic protein of RSV and a pharmaceutically acceptable vector; and a second composition including an immunologically effective dosage of a replication-deficient chimpanzee adenovirus type 63 vector contains a nucleotide encoding an antigenic protein of RSV and a pharmaceutically acceptable vector. The first composition is a primary immunization composition and the second composition is a booster immunization composition, or vice versa. In the present disclosure, the combined vaccine is used for inducing a protective immunity against RSV infection, and a method is provided for generating the protective immunity against RSV infection.

Abstract: A light fixture, comprising a main body box (1), a guide rail head (2) positioned above the main body box (1) and capable of rotating relative to the main body box (1), and a light barrel (3) positioned on at least one side of the main body box (1) and capable of swinging up and down relative to the main body box (1), wherein a radiator (32) and a first light source (33) are arranged in the light barrel (3); the main body box (1) comprises a main body box top cover (11), a main body box bottom plate (12) and a main body box side plate (13) connected between the main body box top cover (11) and the main body box bottom plate (1); and the guide rail head (2) is pivotally connected to the main body box top cover (11), and the light barrel (3) is pivotally connected to the main body box side plate (13).

Abstract: A luminaire includes a lamp barrel having a light source detachably connected with a lens assembly. The lens assembly includes a lens barrel detachably connected with the lamp barrel and a focusing member on the lens barrel. An adjusting assembly includes a rotatable focusing ring, a lens fixing ring and a lens. The focusing ring includes a spiral groove on an inner surface. The lens fixing ring includes a projected rail on an outer surface. The lens barrel includes a bar shaped through hole extending along an axial direction. The projected rail passes through the bar shaped through hole and is mated with the spiral groove by clearance fit. Rotation of the focusing ring acts on the projected rail through the spiral groove and drives the lens fixing ring and the lens forward and backward in the lens barrel to adjust a distance between the lens and the light source.

Abstract: A panel lamp includes a lamp frame, light bars, an upper light diffusing plate, an upper light guiding plate, a lower light guiding plate, a lower light diffusing plate and a middle optical isolation element. The lamp frame includes at least three frame bars successively connected, each provided with an installation groove. Each installation groove is internally provided with one lamp bar, each light bar is provided with an upper lamp body and a lower lamp body. The upper light diffusing plate, upper light guiding plate, middle optical isolation element, lower light guiding plate and lower light diffusing plate are snap-fitted in the installation grooves. The upper lamp body faces a side edge of the upper light guiding plate, and the lower lamp body faces a side edge of the lower light guiding plate. The middle optical isolation element is between the upper lamp body and the lower lamp body.
