Light tube profile with double-sided light output Description

The object described below is a tubular profile as a base body for lighting systems, which can therefore be assigned to the field of lighting technology.

This light tube profile is designed so that light can emerge in two directions without mutual interference.

The aim of the light tube profile with light emission on both sides is to use it as a light tube, with simultaneous, independently switchable and mutually non-influencing direct and indirect lighting in a filigree design.

Current state of the art;

The light tube systems known to the applicants only allow light to exit on one side. This cannot be changed in the systems offered to date, as their stability would be impaired by the introduction of a second light exit opening on the side opposite the intended light exit. The existing profile concept is derived from a tube that is open by one third. The stability is achieved by beads and material beads on the side opposite the light exit.

Construction:

The light tube with light output on both sides is intended to be a supplement to existing light tube systems. The light tube described is compatible with the Orion round light tube system, 0 65 mm from the manufacturer Staff. It can be used for other brands without any problems by adapting the profile design. The basic concept of the light tube system with light output on both sides remains the same.

The material used is an aluminum alloy (AlMgSiO,5). The processing is planned using the continuous casting / extrusion process. The basic idea of the light tube profile presented is a body (1) as a tube in

0 65 mm, which is 25% open on two opposite sides. The stability is provided by internal connecting bars (2). The connecting bars should be arranged at a distance of approx. 30 mm and each should also have a width of 30 mm. In the middle of the two quarter shells connected by the bars there are additional material reinforcements in the form of round, curved noses.

(5). These serve as supports for insert plates (4) and for screwing in screws, with which additional pipes, accessory components, etc. can be attached.

The ends of the quarter shells are curved and profiled inwards, which serves to attach the offered system accessories (3) such as prism covers, blind covers, louvre grids, etc.

In order to allow use on both sides as a direct and indirect light source, the use of innovative lamps with a delicate design is required. Fluorescent lamps from the T 5 series with a diameter of 16 mm are used. The fluorescent lamp sockets are mounted on a slide-in support (4), which also serves as a reflector and prevents the light from shining through to the opposite side. Additional accessories such as terminals, fuses, ballasts, etc. can be mounted on this slide-in support. Treated sheet metal made of aluminum, steel, stainless steel or plastic can be used as materials for the slide-in support. The stability of the light tube is always only created by the connecting bars (2), with the slide-in support supporting stability. In the event that connecting bars interfere with the installation of sockets or other accessories, they can be easily removed. Removing individual bars does not affect the stability of the overall system.

The surfaces of the light tube profile are treated as in the systems used previously and are given a coat of paint.

Advantages of the light tube profile with light emission on both sides:

The advantage of the light tube profile described lies in its universal and flexible application.

In lighting technology in particular, the trend is towards smaller designs while maintaining the same light output. Better integration of the lighting into the architecture and design of the building or room is also possible.

If lighting solutions with light tubes were previously required that were to have a direct and indirect effect, the light tube systems had to be installed either as a direct or an indirect lighting system. Increased material usage, additional installation costs, poorer uniformity in illumination and lower light output on a comparable area had to be accepted. The Lichtrom profile with light emission on both sides enables compact direct/indirect lighting solutions to be implemented without mutual influence and can be switched and used separately .

Further advantages lie in the adaptation and use of existing light tube systems. These can continue to be used without restrictions. A new development of accessories such as connectors, covers, mold pieces, suspensions, etc. is not necessary, as the light tube with light emission on both sides fits harmoniously and fully compatible into the existing light tube system.

In the production of the light tube profile with light output on both sides, previously used tools, machines and devices can be used without major retrofitting, since the previously one-sidedly open profile only needs to be produced in a mirrored manner. Only the costs for producing the connecting bridges are necessary.

By integrating two types of lighting (direct / indirect) into one luminaire body, material is saved and resources are conserved.

Processing of the light tube profile is also possible as before.

The planned use of fluorescent lamps of the T 5.0 16 mm design also takes into account the requirements for rational use of energy and conservation of resources, as these fluorescent lamps are operated exclusively with electronic ballasts and thus work with almost no losses. In order to achieve the same light output as fluorescent lamps of the T 26, 0 26 mm series, around a third less power is required. The electronic ballasts also extend the life of the lamps, a virtually flicker-free start is possible and the unpleasant stroboscopic effect caused by flickering fluorescent lamps does not occur. This also contributes to saving materials and improving comfort for people.

Light tube body in H-shape to enable light to be emitted from both sides Production of a double-sided light exit on a light tube profile. Achieved by: Production of a light tube profile body in &EEgr;-shape (Appendix drawings, Sheet 1, Component 1) with connecting webs (Appendix drawings, Sheet 1, Component 2, or Sheet 4, Component 2) for stabilization. The two opposite sides of the &EEgr; profile are rounded and each correspond to approx. the quarter of a circle. Extruded aluminum AlMgSi0.5, strength F22 is used as the material. The light tube body consists of one part. To lock the built-in components, receiving grooves are designed opposite one another. 2. Stabilization of the light tube profile with double-sided light output through connecting bars Reinforcing the light tube profile and connecting the two quarter shells of the tube profile Achieved by: Connecting bars (2) incorporated in the manufacturing process of the light tube profile. The connecting bars (2) are approx. 30 mm wide and arranged slightly off-center at a distance of approx. 30 mm, and are firmly and permanently connected, positively and force-fittingly, to the half shells (1). The connecting bars are manufactured by punching or compression molding. 3. Insert carrier for system components Integration and fastening of system components such as lamp sockets, ballasts, terminals, fuses, emergency light sockets, batteries, circuit boards, etc. Achieved by: Insertion of an insert carrier (4) made of sheet metal (steel, aluminum, stainless steel) or plastics into the receiving lugs (5) in the middle (axis) of the quarter shells directly below the connecting webs. The insert carrier is made of light-reflecting material to increase the light output. 4. Preventing light from shining through from the opposite lamp The lamp body should allow the integration of two opposite lamps for direct and indirect lighting of a room. Both lamps should be able to be switched separately. When a lamp is in operation, its light must not emerge on the opposite side, but only at the defined light outlet. Achieved by: Installation of the insert carrier (4) into the receiving lugs (5) on the quarter shells of the light tube body. -4-
