These devices find application in various sectors, including industrial automation, consumer electronics, lighting architecture and human-machine interface systems. Known art In the field of signaling and control devices, buttons and indicators bright lights play a vital role in providing an intuitive interface and visually effective between the user and the system. These components are widely used in a wide range of applications, ranging from electronics to from consumption to industrial machinery, from medical devices to transportation systems. However, despite their widespread use, buttons and indicator lights traditional ones have several limitations that compromise their versatility, adaptability and energy efficiency. One of the main problems associated with buttons and indicator lights conventional is their dependence on incandescent or incandescent light sources fluorescence. These technologies, although widely used, have several disadvantages, including high energy consumption, limited lifespan PRAXI Intellectual Property SpA PF / GZ / 147p2024 and poor luminous efficiency. Furthermore, incandescent light bulbs and fluorescent lamps are subject to frequent breakages and failures, requiring a constant maintenance and periodic replacement. These aspects translate into high operating costs and reduced system reliability. Another critical aspect of traditional buttons and indicator lights is their limited flexibility in terms of light output control. Most some of these devices operate at a fixed intensity and do not allow for regulation brightness dynamics. This can cause visibility problems in different environmental conditions, such as direct sunlight or total darkness. Additionally, the lack of granular control over light output limits the possibility of adapt the button to specific application needs or create visual effects personalized. To address these challenges, several alternative solutions have been developed in over the years. One of the main trends is the adoption of technologies solid-state lighting, such as LEDs (Light Emitting Diodes). LEDs offer numerous advantages over traditional light sources, including high energy efficiency, a long lifespan, greater robustness and a better quality of light. However, the effective implementation of LEDs in buttons and indicator lights require careful electronic control to ensure optimal functioning and fully exploit the potential of this technology. Some existing solutions have attempted to integrate LEDs into buttons and light indicators, but often with limited results. Many of these devices are based on a rudimentary control of the light emission, which does not allow for a precise adjustment of color intensity or hue. In addition, most some of these solutions do not take into account the performance variations between individual LED, causing inhomogeneity in light emission and compromising the visual uniformity of the device. PRAXI Intellectual Property SpA PF / GZ / 147p2024 Another aspect often overlooked in existing solutions is the adaptability of the button or indicator light under different operating conditions. Many devices are designed to operate at a fixed voltage and are not capable to adapt to variations in the power supply. This limits their compatibility with different systems and environments, requiring the use of components additional voltage regulation. Finally, many of the existing solutions are designed as standalone devices, without the ability to communicate or integrate with other systems. This lack of connectivity prevents remote control, synchronization with other devices and the implementation of advanced features based on data sharing. In an increasingly interconnected era, this limitation represents an obstacle significant to the widespread adoption of smart buttons and indicator lights in modern application contexts. The purpose of this invention is to address the limitations of existing technologies existing, offering a versatile, adaptable and energy efficient. Combining high-performance LED lights with a sophisticated electronic control system, this illuminated button represents a significant step forward compared to traditional solutions.

The front part of the button of the present invention, being sliding inside the walls, when pressed, it activates switches placed inside on the back. The control electronics is a fundamental component of the light button, as it is responsible for the management and control of the LED illuminators. In In particular, the control electronics is able to perform the regulation of light intensity (dimming) in a range from 0% to 100%. This functionality allows you to vary the brightness of the button continuously and precise, adapting it to environmental conditions or user preferences. Furthermore, the control electronics implements a dot correction process, i.e. PRAXI Intellectual Property SpA PF / GZ / 147p2024 compensation for emission differences between individual LED illuminators. This function is of fundamental importance to ensure proper lighting uniform and homogeneous, even in the presence of variations in the characteristics of the individual LEDs.

The button or indicator light solid state comprises one or more LED illuminators, which constitute the element central light button. LED illuminators are electronic components solid-state that emit light when passed through an electric current. The choice to use LED illuminators gives the illuminated button numerous advantages over traditional lighting technologies, such as light bulbs incandescent or fluorescent lamps. LED lights have a very long lifespan, often longer than 50,000 hours of continuous operation. This means that the button or indicator solid state light requires minimal maintenance over its life cycle long life, with a reduced need to replace LED illuminators. The long life PRAXI Intellectual Property SpA PF / GZ / 147p2024 LED rating also contributes to reducing operating costs and of the environmental impact associated with the disposal of exhausted lamps. The invention also aims to provide speed and simplicity of maintenance by having a button top that is removable, making replacement easy of the LED illuminators engaged in contact with the display without damaging or tamper with the control electronics of the invention. Another significant advantage of LED illuminators is their ability to emit light in a wide range of colors and wavelengths. This is possible thanks to the use of specific semiconductor materials and the possibility of combining LEDs of different colors to obtain the desired color mix. In the button or solid state indicator light, this feature allows you to customize the visual appearance of the light button and adapt it to your needs application-specific, such as color-coded status or alarm reporting distinct. In various embodiments of the present invention, the following may be used: single large LEDs for high intensity illumination, or smaller LED arrays for even light distribution across a surface wider. In the solid-state pushbutton or indicator light, LED illuminators are integrated into a single compact, sealed unit protected from above by the display. This design ensures the protection of internal components from harmful agents external factors such as dust, humidity and chemical agents, increasing the lifespan and the reliability of the illuminated button. The absence of moving parts or fragile elements, like the glass of traditional light bulbs, it makes the button or indicator light solid state particularly suitable for use in industrial environments or in difficult environmental conditions.

These LEDs are connected to LED drivers that manage their power supply. and control. In a preferred configuration, four LEDs are used RGB connected to twelve LED drivers, with three drivers for each LED, one for each color (red, green, blue). The LED drivers are in turn connected to a microcontroller, which plays a central role in controlling and managing the light button. Going into specifics, the electronics controlling the light emission of the solid state light button, installed inside the walls of the same button, includes at least one LED illuminator control circuit, a microcontroller and a communication interface. These components work in synergy to allow precise and versatile regulation of light intensity and the wavelength of the light emitted by the LED illuminators. The LED illuminator driver circuit is designed to provide the current necessary for the operation of the LEDs, while ensuring control accurate control of light emission parameters. This circuit includes preferably dedicated LED drivers, which are able to regulate the current supplied to each LED based on the control signals from the microcontroller.

The microcontroller is the heart of the electronic emission control system PRAXI Intellectual Property SpA PF / GZ / 147p2024 bright. It is programmed to manage all the functions of the button bright, including adjusting the intensity and wavelength of the light emitted. The microcontroller communicates with the LED drivers through an interface control, which can be digital or analog depending on the specification implementation. Through this interface, the microcontroller sends to the drivers LED signals needed to set the desired light intensity and select the emission wavelength. As for the regulation of the light intensity, the microcontroller is preferably capable of generating control signals that allow for variation the current supplied to the LEDs in a continuous and linear manner. This allows to obtain a dimming effect, or brightness regulation, in a range that goes from 0% to 100% of maximum intensity. The wavelength selection of emission is carried out by the microcontroller by acting on the LED drivers in order to independently drive the different colored LEDs in the button bright: in the case of RGB LED illuminators, for example, the microcontroller can control the red, green and blue LEDs separately, varying the intensity of each color to obtain a wide range of tones and shades; similarly, in the case of LED illuminators with other color combinations, such as white warm and cool white, the microcontroller can adjust the intensity ratio between the different LEDs to obtain the desired light tone. The communication interface of the electronic control system allows you to receive commands and settings from outside, i.e. from the system in which it is employee. The control can be of different types, with or without communication protocol. In the version without communication protocol from the user system, the ignition or turning off the button display or part of it can be activated with simple digital on-off control: in this case the light intensity and the the emission wavelength will be the one pre-programmed in the microcontroller. PRAXI Intellectual Property SpA PF / GZ / 147p2024 In the version with communication protocol the button is controlled and fully and dynamically controlled by the user system which will be able to send control and activation commands for each individual LED using a protocol of standard type supported communication such as but not limited to limiting or constraining: USB, I2C, SPI, RS-232, RS-485, etc. Thanks to the combination of LED driver circuit, microcontroller and communication interface, the electronic control of the light output of the solid state button offers a wide flexibility in intensity adjustment and of the wavelength of the emitted light.

In this way, even if the individual LEDs have slightly different emission characteristics, the The overall brightness of the array is uniform and free of visible imperfections. In addition to the precision resistor network, the dot correction circuit may include also an optical feedback system, consisting of one or more brightness sensors (photodiodes or phototransistors) placed near the LED array.
