Industrial equipment signal lights: the classification and use of machine tool work lights

Machine work lights are divided into: short arm machine lights, long arm machine lights, explosion-proof machine lights, hose machine lights

Machine tool industry application: CNC machining lighting, grinding machine LED work light, CNC machine work light, engraving and milling machine LED work light, glass engraving machine light, spring machine work light, electric control cabinet LED lighting, electronic equipment work light, automation Equipment lighting.

The light source of the machine tool illumination adopts Taiwan imported 2835 lamp beads, high-power lamp beads and 1-3W high-power lamp beads. These light sources are the best choice for lighting fixtures due to their high performance, low light decay and low thermal resistance. The mounting method has a screw fixing base and a magnetic fixed base for various mobile working situations.

Working principle of machine tool work light

The fluorescent tube is filled with a low-pressure argon or argon-helium mixed gas and mercury vapor, and on the inner surface of the glass fluorescent tube, a phosphorescent fluorescent paint is applied, and a filament coil made of tungsten is provided at both ends of the tube. . When the power is turned on, the current is first heated by the filament and the electrons are released. The electrons will turn the gas in the tube into a plasma and increase the current in the tube. When the voltage between the two sets of filaments exceeds a certain value, the tube begins to generate. Discharge, the mercury vapor emits ultraviolet light at 253.7nm and 185nm wavelength, and the phosphorescent fluorescent paint on the inner surface of the fluorescent tube absorbs ultraviolet rays and emits longer wavelength visible light. The color of the emitted light is controlled by the proportion of the phosphorous component, while the glass tube prevents harmful ultraviolet rays and other harmful substances such as mercury from leaking out.

There is a positive feedback relationship between the discharge current of the fluorescent tube and the on-resistance: when more current flows into the fluorescent tube, more gas is ionized, so that the on-resistance in the tube is continuously reduced, so that more current is generated. Into the fluorescent tube. If the fluorescent tube is directly connected to a fixed-voltage power supply, the fluorescent tube will be burned quickly due to the rising current, so an auxiliary circuit is required to control the current entering the fluorescent tube at a fixed level, and this current control circuit is usually Known as the ballast. The ballast is actually an inductor. When the on-resistance drops to a very low level, the ballast's fixed inductive reactance and copper consumption cause the on-current to approximate a fixed value and start to work stably. Traditional ballasts need to be paired with a small component called Starter (commonly known as “Starta”) to make the differential between the filaments enough to discharge the fluorescent tube. The latest electronic ballasts do not. A starter is required because the start-up work has been included in the ballast.
