An optical acoustic panel 100 for absorbing sound and providing a daylight appearance and a luminaire are provided. The optical acoustic panel 100 comprises a first side 114, a second side 104, a micro perforated foil 110 and a spacing structure 108. The first side 114 receives sound. The second side 104 is opposite the first side 114 and receives light. The micro perforated foil 110 comprises sub-millimeter holes 112, is light transmitting and is arranged at the first side 114. The sub-millimeter holes 112 are entrance holes of a cavity. The spacing structure 108 spaces the first side 114 at a predefined distance from the second side 104. The spacing structure 108 comprises a plurality of light transmitting cells 106. The light transmitting cells 106 comprise a light transmitting channel 118, a light exit window 122, a light input window 120 and a wall 116. The light transmitting channel 118 collimates a part of the light received at the second side 104 of the optical acoustic panel 100. The light transmitting channels 118 extend from the first side 114 towards the second side 104 and are filled with air. The light input window 120 is arranged at the second side 104. At least a part of the light exit window 122 being arranged at the first side 114. The wall 116 is interposed between the light input window 120 and the part of the light exit window 122. The wall 116 encloses the light transmitting channel 118. At least a part of the wall 116 being reflective or transmissive in a predefined spectral range for obtaining a blue light emission at relatively large light emission angles with respect to a normal to the first side 114.

摘要:
A new prefabricated wall panel is the basic unit of a new, more efficient and stronger wall system. The wall panel is manufactured from a plurality of foam sections sized to leave vertical and horizontal voids into which concrete is later poured, each foam section having an inner and outer surface and two sides; and a plurality of fastening strips. The fastening strips are longitudinal metal strips being situated between the sides of two foam sections. Each fastening strip has two longitudinal fastening strips projecting perpendicularly to the longitudinal fastening strip and the fastening strips being adjacent to the outer surface of the two foam sections. The fastening strip also has a plurality of clearance holes in the longitudinal fastening strip, a plurality of embed tabs projecting from the edge opposite the fastening strips, each embed tab having at least one hole, and between each pair of embed tabs, a foam tab to hold the two inner sides of the foam sections in place and partially separate the foam sections from the concrete to be poured into a form.
摘要:
Embodiments relate generally to plastic wall panels. Wall panels are formed by rotational molding processes and may be used in sound attenuation barriers or other wall or building structures. Some embodiments include reinforcing structure. The reinforcing structure may be configured to effectively support a plastic shell of the wall panel in a way that allows some relative movement between the plastic shell and the reinforcing structure.

摘要:
A wall system (110) is disclosed which is mounted onto girts (114) on a building. Rectangular foam blocks (126) are installed between the outer flange of the girts, and the inside surfaces of the wall panel (112). Some vertically spaced apart blocks are located behind the wall seams, and other blocks are located intermediate the seams. The spacing created by the blocks allows for a blanket of insulation (118) between the blocks and the support members to be expanded, improving the system's insulative properties.
