Description

Application area

The proposed technical solution relates to decorative lighting systems, can be used to create an imitation of the starry sky in various rooms, as a souvenir, as a decorative floor lamp, as a New Year's flickering illumination or Christmas tree decoration.

State of the art

A device for creating a starry sky, described in patent EP 1102231. This device contains a bearing surface with holes in which the ends of the optical fibers are inserted. On the reverse side of the bearing surface, the optical fibers are bundled and connected to a projector from which light is transmitted to the optical fibers. There can be several projectors. The color wheel is used to create the effect of flicker and color change.

This device contains moving parts: wheels and systems of forced cooling of the projector lamps, which are necessary in systems of this type, which contributes to the appearance of extraneous noise that causes irritation to the user. The closest analogue is the device described in patent RU 69195 U. This decision is made as a prototype. A decorative fiber optic lighting device, consisting of a carrier surface with openings arranged in the required sequence, a projector located on the back of the carrier surface, and the required number of optical fibers, with one end of each optical fiber connected to the projector and the ends of the optical fibers connected in a bundle, characterized in that as a projector, a device is used comprising a microprocessor defining a program of at least one emitter based on e powerful LED and related septic fiber by the focusing system placed between the LED and the second ends of the optical fibers, wherein between the microprocessor and the LED has a pulse width modulator and the electronic switches (breakers

electric current supplied to the emitter), and the number of the last two is equal to the number of LEDs, while there is the possibility of creating a flicker effect. The disadvantage of this device is that to control the modes of the flicker effect, you must manually switch the modes by turning on the toggle switches in a special program selection device. When placing the device over a suspended ceiling (under which a bearing surface protrudes), in order to switch to another program mode, it is necessary to dismantle the suspended ceiling. This is extremely inconvenient.

Effect: provides remote switching of modes of flicker effects programs; simplified design; provides enhanced functionality of the device.

Utility Model Implementation

The claimed technical result is achieved due to the fact that in the device of decorative fiber optic lighting containing a projector and the required number of optical fibers, while one end of each optical fiber is inserted into the hole of the bearing surface, and the second is connected to the projector, and the second ends of the optical fibers are connected in a bundle , a device containing a microprocessor defining a program was used as a projector, it also contains at least one emitter made on the basis of a powerful LED and associated with optical fibers located between the LED and the second ends of the optical fibers, the device also contains pulse-width modulators and electronic keys, the number of the latter two being equal to the number of LEDs, while it is possible to create a flicker effect, also contains devices for selecting programs of the flicker effect, characterized in that the pulse-width modulators are built into the microprocessor, the device further comprises a remote

flicker program control and a receiver configured to receive signals at a frequency of the remote control, and connected to a program selection device.

Remote switching of the modes of flicker effects programs is provided by using the remote control. The simplification of the design is ensured by eliminating the focusing system from the device by amplifying the power of the emitters supplying light to the optical fibers, the simplification is also due to the incorporation of pulse modulators into the microprocessor and by eliminating the attachment of the device to the bearing surface. The latter also provides an extension of the functionality of the device due to the fact that it can be used not only together with the bearing surface to create an imitation of the starry sky in various rooms (when it is required to insert optical fibers into the holes of the bearing surface), but also as decorative lighting like a floor lamp (with fixing on the wall), like a Christmas decoration, like decorative lighting of transparent ceilings or panels by installing the device behind them, as a result of which it creates a salute effect through the transparent th or ceiling panel. Optical fibers (2) (see Fig. 1) of the device are assembled in bundles (3), while some ends can be used both for inserting into the holes of the bearing surface of the ceiling and simply hanging out. The overall effect of the device is to create the effect of illumination of the optical fiber.

The device consists of a housing (1), a power supply (9), which can be used, for example, NFM-10-5 PBF, microprocessor (5), emitter (6), pulse-width modulator (7), electronic keys ( 8), optical fibers (2), radiation receiver (4) and remote control (10). The microprocessor (5) contains a built-in memory with dynamic effects programs and a device for selecting these programs (not shown in the drawings). The emitter (6) is made on the basis of a powerful LED. A decorative fiber optic lighting device may contain either one emitter (6) or several. In addition, the emitter (6) can be of any color. The choice of color of the emitter (6) depends only on the desired decorative effect.

The emitters (6) can be implemented, for example, on the basis of high-power LEDs L-5013UBC-TL (blue), L-5013UEC-TL (red), L-5013PGC-TI (green).

A pulse-width modulator is built into the microprocessor. The microprocessor can be implemented, for example, on the basis of the PIC16F876A microcircuit or in the form of an Atmega 162-16 programmable microcontroller with integrated pulse-width modulator channels.

Pulse-width modulators (7) are designed to convert an electronic signal coming from a microprocessor (5) into a pulse-width modulation signal. The number of pulse-width modulators (7) is equal to the number of emitters (6). Pulse-width modulators (7) allow you to control the brightness of each emitter (6) using an electronic key (8), which makes it possible to obtain a flicker effect.

Electronic keys (8) act as interrupters of the electric current supplied to the emitters (6), i.e. turn on or off the emitter (6). Thus, the flicker effect of the emitter (6) is realized with clearly defined on / off states. Such switching occurs with a very high frequency (about 8000 times per second) and different pulse duty cycles. The flickering of such a frequency is indistinguishable for vision and is perceived as a change in the brightness of the emitter (6) when the duty cycle of the pulses changes. The number of electronic keys (8) is equal to the number of emitters (6) and pulse-width modulators (7).

Electronic keys (8) can be implemented, for example, on a high-speed field-effect MOSFET transistor P-channel irf19014 or transistors IRFL024N, IRLL2703. The device decorative fiber optic lighting with a single emitter (6) works as follows.

A power cord is connected through connector (12). The power is supplied from the connector to the power supply unit (9), which through the microprocessor supplies the rated current supplying the emitter (6) through the electronic key (8). According to the program embedded in the microprocessor (5), an electronic signal is transmitted, which enters the pulse-width modulator (7).

In a pulse-width modulator (7), the electronic signal is converted into rectangular pulses with a variable duty cycle, controlling the electronic key (8). The lower the duty cycle, the higher the brightness of the emitter (6).

The light from the emitter enters the second ends of the optical fibers (2) and, passing along their entire length, reaches the ends, and gives the light effect of a point of a certain color at each end of the optical fiber, depending on the color of the emitter.

The microprocessor (5) contains several programs that differ, for example, in the flicker frequency and brightness of the emitter 6 - LED, as well as in the rate of change of brightness. You can select a program using the remote control. From the control panel (10) through the transmitter (11) a signal of a certain frequency is supplied, which is received by a receiver located in the device.

The receiver (4), having received a certain signal, to which a certain code is assigned, transmits it to the microprocessor (5), which includes one or another flicker program in accordance with the given code.

As a receiver (4) and a transmitter (11), for example, an FSK module at a frequency of 433 MHz with SPI can be used (for a receiver: RFM01-433-D, for a transmitter: RFM02-433-

D) Or it can be used as a receiver (4) a supersensitive radio receiver with laser tuning of the circuit during the manufacturing process (for example, RR3-433 PBF TELECONTROLLI), and as a transmitter (11) a radio transmitter with amplitude modulation, a SAW resonator and an external antenna (for example, RT5 -433 PBF TELECONTROLLI).

The operation of the device is completely similar to the principle of operation of the prototype when creating a flicker effect, when it is necessary to obtain multi-colored dots at the ends of the optical fibers.

The decorative fiber-optic lighting device is mounted in any convenient place by fixing the case, and unlike the prototype, it can be used not only to create the effect of the starry sky, but also as a souvenir, floor lamp, Christmas tree decoration or Christmas flickering illumination (see the general view of the device in the assembly on figure 3).
