Description

Tilman Henckell Decorative controllable semiconductor light beam luminaire Page 1 of 9 Description

Conventional ceiling or wall lights use filament-based lamps, which have a high power consumption and, after a while, fail due to filament breakage and have to be replaced. The light from such lamps is largely open and flat. In many cases, the light provided is over-dimensioned, i.e. it consumes more energy than is necessary for the application. A large part of the energy is converted into waste heat, but has to be generated/paid for!

The invention presented here turns this oversized, cost-intensive "festive lighting" into a festive and decorative lighting that saves operating costs and is glare-free. Thanks to the built-in voltage storage, it can be arranged as desired and used without major installations, for example in otherwise poorly lit staircase areas. Triggered by IR control (internal or external) and limited by an internal automatic timer and only released by a twilight sensor, light is only generated where it is needed and only for as long as necessary. It can also be used purely decoratively and supplied for this continuous operation via a power supply from the lighting network.

Since the lamp according to the invention is constructed with semiconductor-based lamps (super-bright LED, now also sufficiently bright in WHITE), there is no high heat loss, operating costs are reduced, the service life is almost unlimited, and the switch-on current surges that occur with PTC thermistors (light bulbs) are eliminated. The operation of the lamp presented here is energy-friendly and is further enhanced by its decorative effect, since its light does not simply diffuse into the room, but shines as a single or multiple beam at a selectable angle onto the wall/ceiling in question and highlights its structure, creating interesting, varied light and shadow effects. Because the light is indirect, it is glare-free.

The presented design allows the user to individually adjust the beam path of the lamp to the installation location and the taste of the viewer.
The light emission of the lights can be arranged in a row (i.e. parallel beam path) or even radial (i.e. arranged around a center). Additional attractive effects can be achieved by combining LEDs of different colors. The beams of each of the arranged LEDs can vary in brightness, shape and color. If the light is equipped with additional program memory control, each beam can also change its color, and the beams can also move horizontally or around the center - flickering, jerking or in flowing transitions. Even opposing movements of rotating beams are possible. Control of the

Radiation in terms of color, shape and intensity from, for example, music sound sources - direct or indirect - is also taken into account, as is central control of many such installed lights, even if they are distributed across different rooms. The design options based on this invention presented here are very diverse. Accordingly, the application of the invention is not limited to, for example, staircase or cloakroom lighting, but can also be used as wall or ceiling lights in cafes, restaurants, libraries, hotels, meeting or exhibition rooms to create a pleasant eye-catcher that invites people to linger. The market is virtually unlimited. Therefore, there are good sales opportunities for the invention presented, not least because of aesthetic aspects while simultaneously appreciating the environmental aspect.

function

The lamp is formed by a projection of the light emission of super-bright single or multi-coloured LEDs, which are arranged in a beam tube - individually or in multiple groups - in such a way that their light is not diffuse, but rather emerges from this tube profile as a beam directed in one direction. The beam tube of each LED arrangement can be swivelled and is set up in such a way that the light beam emanating from it falls on the mounting surface at a definable angle of e.g. 5..45° in such a way that a slim, intensely luminous parabola is projected onto it. The resulting light is glare-free. The lamp can consist of just 1 LED in 1 beam tube, or several LED-equipped beam tubes are arranged in a line or around a centre point in such a way that their light emerges parallel and/or in different directions (e.g. 60° to each other). Arranged in parallel, a "light curtain" is formed, while concentrically arranged a "star" with as many beams as there are LED beam tubes / LEDs switched on. The mounting mechanism with the beam tubes is hidden under a decoratively designed cover. Underneath this are, for example, adjustment screws with which the angle of incidence of each light beam on the mounting surface (wall or ceiling) can be individually adjusted. This also determines the shape and length of the respective beam cut through the mounting surface. The slim beam tubes themselves can also be mounted visibly and thus serve as a decorative element themselves.

If required, the luminaire contains an infrared-controlled sensor that switches the light on - depending on a twilight switch. The sensor either reacts to body heat or picks up an IR light pulse from an "IR satellite" that is already installed at some distance (possibly on both sides of the lamp) so that the lamp is switched on early when a person moves towards this area. Wiring is not necessary for this type of triggering. The dark switching is caused by a timer circuit that shortens the already low power consumption. The individual LEDs can be colored (e.g. blue) as well as white. They are controlled by electronics that, in advanced versions, determine not only a time sequence but also their brightness and their combination with one another. The user of the lamp can also regulate the options offered by the electronics themselves using switches or potentiometers or even switch them using a remote control. Ultimately, all lamp parameters (play of colors, running speed, brightness change, etc.) can also be controlled by an electronic program memory, which in turn can be initiated by a remote control. Several LEDs combined in only one beam tube, e.g. in the colors RED, GREEN, BLUE allow

Depending on the control, a beam in mixed colors is generated. Electronics ensure a smooth transition or switching of the beam color. This electronics can in turn be controlled by a microphone or music signal if required, which, for example, influences the colors depending on the frequency or the brightness of the light beams depending on the volume. The beam is bundled by the position of the LED in the beam tube or by focusing using a lens or pinhole. The cover/stand housing of the LED beam tubes can, if it is metallic, be mounted in an insulated manner to serve as a sensor surface if the light is to be switched on or off simply by touching it.
