RU165571U1 - LAMP WITH OPTIONAL CONTROL FROM A SMARTPHONE OR COMPUTER THROUGH AN AUDIO CODED SIGNAL - Google Patents

Abstract

A lighting lamp, characterized in that it has the ability to remotely control on, off and brightness wirelessly from a standard smartphone, tablet or other computer, or other devices by using an audio encoded digital signal.

Description

The utility model relates to lighting engineering, as a replacement for widely used standard lighting lamps (compact fluorescent energy-saving or LED) indoors in the home and in production.

Widespread lamps (LED and energy-saving discharge lamps) designed for universal use, as a rule, exclude the possibility of a smooth change in the brightness of the glow remotely. Dimmers designed for incandescent lamps cannot control such lamps because the internal light source control circuit (LED circuit or gas discharge tube) must necessarily stabilize currents that can be influenced by various factors - temperature, spread of element parameters, etc. Thus, to change the brightness, it is necessary to directly influence the control circuitry, which is located in the lamp housing.

There are solutions to this problem using a radio frequency signal receiver from a control panel, computer or smartphone in WiFi, Bluetooth, ZigBee and other formats. For example, RF patent 115140, Н05В 37/00, 07/15/2011. However, these remote control options have a very high production cost. The price of such a lamp is several times higher than the cost of a standard lamp with similar parameters and quality, which inhibits widespread use.

Chandeliers with a remote control (IR, radio control) appeared on sale. In them, the command receiver is built into the chandelier body. But, firstly, most often a chandelier or other type of lighting is selected for the specific design of the room and the taste of the user, and the vast majority of chandeliers and lamps do not have such built-in control (especially spotlights) and often the choice falls on them. In addition, not all users would like to change what they already have and fit into the interior. Secondly, such chandeliers can be controlled by only one full-time remote control, without the possibility of using other universal devices, such as smartphones and computers.

Also known lamps with remote control by infrared coded signal from the remote control (RF patent 73759, H01J 61/30, 10/15/2007). In my opinion, this is the closest prototype to this utility model. The advantage of this solution is a fairly low cost. However, the disadvantages do not allow it to be applied widely. Firstly, in most lighting fixtures (chandeliers, sconces, etc.), it is impossible to guarantee the penetration of infrared radiation into the receiver (especially when screwing the cap into the cartridge, an unpredictable orientation in space can be obtained), since direct visibility from control panel to the receiver photodiode (a reflected signal is sometimes possible, but far from guaranteed). Secondly, control, although not expensive, requires a special control panel, and standard computers and smartphones, for the most part, do not have an infrared port.

This utility model is devoid of these disadvantages. The cost of production of such a lamp is very slightly different from a similar standard lamp. Management can be done with any standard smartphone, tablet or other computer with the ability to play sound, as well as a special remote control with an extremely low cost. The sound can reach the lamp from the control device not only in a straight line (unlike infrared radiation).

Typically, standard LED or discharge lamps consist of the elements of the block diagram shown in FIG. 1. The lamp power (alternating current of the electric network) is supplied to the diode rectifier with a smoothing capacitor (1). The high-voltage driver (2) can be performed according to various schemes (on a bipolar, MOS, CMOS, IGBT transistor, with a choke or transformer, etc.). The driver (2) controls the output current supplied to the Light-emitting elements (4) (LEDs or gas discharge tube) by applying an alternating voltage of adjustable duty cycle to the control input from the PWM controller (3). Data on the current or voltage in the light emitting elements is supplied to the PWM controller (3) for stabilization. PWM controller (3), in accordance with the algorithm laid down in it, changes the width of the pulses supplied to the Driver (2) depending on the output current or voltage.

The present utility model (Fig. 2) differs from the standard lamp by the presence of a Microphone (5), which is mounted in the lamp housing with an opening for receiving audio data from the outside. The encoded sound signal of the brightness change commands (and others), received by the Microphone (5), is fed to the PWM controller (3). Depending on the model of the controller (sensitivity of its input), a simple amplifier stage on a single transistor with an RC circuit may be required to reduce interference from other frequencies. PWM controller (3), in accordance with the program laid down in it, receives and decrypts the input signal and, accordingly, corrects the width of the pulses supplied to the Driver (2), thus, controls the output current and the load voltage (Light-emitting elements (4) ) in a wide range from zero to maximum.

A lamp (this utility model) can be installed in place of any standard lamp, for example, in a chandelier, sconce, ceiling spotlights, floor lamps, etc. The only condition is that there should be the possibility of sound penetration to the lamp housing from the room, that is, there should not be a sealed ceiling (in normal rooms this practically does not happen).

The increase in the cost of the lamp in production with this improvement is extremely insignificant, calculated in units of percent.

As a control device, a smartphone, tablet computer, laptop, desktop computer, and a special sound control panel can be used. You can also develop a device that can, while working on a network (Ethernet, WiFi, etc.), receiving commands from outside, for example, via the Internet, or working according to a specific timer algorithm, send commands to control the lighting in the room through its loudspeaker . The range from the control device to the lamps is the limits of this room (more precisely, the sound heard by the microphone).

Software is installed on the control device, which can control several different groups of lighting devices at once. Initially, in her new lamp, her identifier code (ID) was not recorded in her memory. When replacing a lamp, it is enough to supply power to it (only to all lamps of this lighting device or group of lamps), enter the lamp programming mode on the control device, set the group number (ID). At the same time, the control device will send to all the lamps to which the power supply in the room is supplied, a programming command that contains the ID of this lamp group. All lamps that are currently turned on by an external electric switch, that is, with power supply, will accept this command code and change their ID, storing it in the non-volatile memory of the controller. In the same way, turning off one group of lamps with an electric switch and turning on another, you can set a different ID for this group. After setting all the lamps, you can turn on all the electric switches and turn off the extra groups from the control device, set the brightness of the lamps you need at the moment. At the same time, the lamps can always remain energized, and the on / off state is already set remotely from the control devices. It is possible to provide an emergency option to turn on the lamps if the control device is not currently available, for example, by briefly turning off the power twice and turning on the electric power switch. An unlimited number of smartphones, tablets, etc. can simultaneously be control devices in one room. Also, the same smartphone (or other device) can control groups of lamps in other rooms.

The command code must contain the identifier of the start of data transfer to the lamps, the ID of the lamp group, the command number and the brightness setting data. To improve noise immunity, it is possible to transmit the checksum of sending data, as well as repeat the sending of the command 2-3 times.

It is possible to use LED lamps not only in white, but also in certain color spectra (red, green, blue). It can be various lamps, the installation of a combination of brightnesses which can achieve different color temperatures of mixed light. And also one lamp in which one controller with one microphone (and general power supply) can control three high-voltage drivers with LED emitters of various colors (RGB). Thus, you can easily change the color combination of lighting at any time, changing the colors of different groups of lamps or lamps.
