Abstract

Signal light for machines and systems that indicates the operating status.

Description

The state of the art:

In the case of machines and systems, the operating status is indicated by signal lights. These signal lights are usually made of plastic. The signal lights indicate the operating status of machines and systems. This operating status is displayed in colour: red = system stopped, yellow = system being set up, green = system running. The degree of protection is generally not very high.

The problem:

With conventional signal lights, the different paint cans are pushed into one another. This gives the usual image of a traffic light. But this also creates many corners and edges that are difficult to clean. A central chip illuminates the colored cans. If contamination occurs, the signal color is now difficult to recognize. The operating status cannot be recognized or can only be recognized with difficulty. This can and does result in operational disruptions. The lights are irreparable and therefore a disposable product (sustainability).

The solution to the problem:

In my construction, the housing is a clear or satin-finish Plexiglas tube, if necessary real glass that has no edges or shoulders. It's slim and easy to clean. The risk of a signal being overlooked is therefore very low. The LED flex circuit boards I installed emit a robust light and are very easy to recognize. The LED flex board has one to five areas, each with one color (red-yellow-green-blue-white). The flex board is glued to a round anodized aluminum tube. At the seam of the flex board there are 3 soldering points for mechanical connection.

The LEDs have a beam angle of 120°. Due to the extensive bonding of the flex board on the tube and the beam angle of the LED of 120°, a very good all-round view is achieved and the signals can be easily recognized.

Separators are installed to delimit the color areas. These are made of black plastic and are made with a guide spring. The bulkheads with guide springs are inserted into a groove in the aluminum tube and glued. The signal light is completely screwed and can therefore be dismantled and repaired. Due to the chamber system of the signal light, even a color-blind person can interpret the signal correctly (traffic light system).

A strain relief is installed in the connection piece by means of a stud. This prevents the wires from tearing off. The connection options are diverse: Directly mounted housing sockets, device plugs, cables with plugs or free cable ends.

The built-in flat gaskets are selected for the respective area of application. These areas of application can be, for example, clean rooms or food areas. The composition of the rubber and its color is selected accordingly.

The metals used in the lights are also selected for the intended use. Anodized aluminum is used for the most part. But stainless steel in V2A or V4A quality is also used for special applications. (foot area)

The advantages:

The great advantage of these signal lights is based on the solid, slim and no-frills construction and the resulting durability. The optics are high quality and the signals are easy to see. Downtimes are reduced, signals are recognized quickly and costs are reduced. By installing LED lines, little power is consumed and the lights only heat up minimally. The high degree of protection (IP65) enables a wide range of applications thanks to the static seals. The sustainability of the signal light is self-explanatory.

Claims (12)

Signal light for machines and systems that indicates the operating status. signal light after claim 1 , characterized in that the signal light is sealed by O-rings. (3) Signaling light according to one of the preceding claims, characterized in that the metal parts of the signaling light are made of anodised aluminum and/or stainless steel. (1, 2,4, 8) Signal light according to one of the preceding claims , characterized in that the LED flex circuit boards of the signal light are glued to a round aluminum tube. (7 and 8) Additional soldering points at the interface of the flex circuit board also prevent the flex circuit board from coming loose. Signal light according to one of the preceding claims, characterized in that the housing consists of Plexiglas and has no shoulders. (6) Because of this, it is easy to clean. Signal light according to one of the preceding claims, characterized in that flexible LED boards are installed in the signal light (7). The flex circuit boards are installed from one level to five levels (red-yellow-green-blue-white) according to the order and produce a robust light. Signal light according to one of the preceding claims, characterized in that partitions (5) are installed in the signal light, which prevent the light from escaping from chamber to chamber. The bulkheads are provided with a tongue that is inserted and glued into a groove in the aluminum tube. Signal light according to one of the preceding claims, characterized in that a strain relief system is installed in the connection piece (1). (9) Signaling light according to one of the preceding claims, characterized in that the signaling light can be expanded at will through the central aluminum tube with the external threads (8) worked on. Signal light according to one of the preceding claims, characterized in that the wires of the connection plug, connection cable or housing plug are routed through an open groove in the end of the aluminum tube and can thus be optimally soldered to the flex circuit board. Signal light according to one of the preceding claims, characterized in that the wires of the connection plug, connection cable or housing plug are soldered directly onto the flex circuit board. Signal light according to one of the preceding claims, characterized in that an aluminum counter bearing (4) is installed, into which the aluminum tube (8) with the flex circuit board (7) is screwed and into which the connecting piece (1) is screwed. The mounted O-ring in the counter bearing (3) prevents a rattling noise from the lamp. This system allows the lamp to be dismantled and repaired.
