Incandescents:

An incandescent lamp is a lighting device that works on the principle of converting electricity into light energy. Incandescents produce light by heating a filament in the bulb made of tungsten wire. This wire is heated to an extremely high temperature, causing it to glow brightly. The heat generated by the light, in turn, generates more light.

The process begins when electrical current flows through the filament of the bulb and a chemical reaction occurs. This reaction emits energy in the form of rays, often referred to as “black-body radiation.”The rays then strike the glass enclosure of the bulb, which produces visible light.

The electricity used to power the filament can come from any type of power source. However, it is important to select an appropriate lamp wattage that is not too high. A lamp with a higher wattage than necessary may cause the filament to overheat, leading to shorter bulb life.

Neons:

Neon lighting uses an electrically charged gas, or “neon gas”, to create a light source. Neon lighting works on the principle of electrical discharges inside a sealed glass tube containing a low-pressure neon gas. When an electrical current is applied to the tube, the electrons of the gas become “excited”, triggering a chemical reaction which produces visible light.

Neon lighting is often used for decorative or outdoor lighting applications. It is also popularly used for advertising and signage due to its long lifetime and bright color. Neon lighting is also well-suited for applications requiring low power consumption and dimming capabilities.

Neon lighting systems are typically composed of a transformer, which converts the electrical current coming from the power source; and a power supply containing the electrodes, rectifier and meter. The transformer is required to create the required voltage and current for the neon light to work. The electrodes provide the electrical connection between the power supply and the glass tube. The rectifier is used to control the flow of electricity in the system.

C2A application field and working principle:

C2A, or Constant Current and Auto Adjustable Voltage, is a technology used in lighting and power systems to provide automatic adjustment of the voltage in response to changes in the load. C2A technology uses a constant current supply to regulate the voltage, preventing the lamp from going dark in the event of an overload. In addition, the technology also adjusts the voltage so that the lamp or device can operate at optimum efficiency.

The principle of operation of C2A technology is simple. The circuit monitors the current that is drawn by the lamp or device and automatically adjusts the voltage to prevent any overloading. When more current is drawn, the circuit increases the voltage to compensate, or vice versa. This way, the current is kept at the desired level and the voltage is adjusted to the right value.

The main applications of C2A technology are in lighting systems such as street lights and traffic signals. In addition, it is also used in power systems to supply uniform voltage and current to various electronic components.
