Does a Tungsten Iodine Lamp Have an Ignition Capacity?

Iodine tungsten lamp has ignition capacity. An iodine tungsten lamp is a kind of tungsten filament lamp filled with iodine vapor for a chemical reaction. It is often used in indoor and outdoor lighting places with high illumination requirements and high installation points. This kind of lamp has a high degree of thermal light source, and there is a risk of burning combustibles on the outer wall of the lamp tube in a short time. Therefore, it is of great significance to understand the ignition ability of iodine tungsten lamp to combustibles for fire prevention and fire investigation.

There are two main factors affecting the ignition capacity of iodine tungsten lamp: power and voltage The influence of iodine tungsten lamp power on surface temperature is positive correlation under the same power, the heat emitted by iodine tungsten lamp increases gradually and accumulates with time. At this time, the surface temperature will gradually increase and conform to the exponential growth law. After working for some time, the heat exchange between the lamp and the outside world gradually reaches equilibrium, and the surface temperature is stable. At this time if the power of the iodine tungsten lamp increases, the surface temperature will also increase, and the ignition capacity will be enhanced.

The voltage of an iodine tungsten lamp will also positively affect its ignition capacity. When other conditions are constant, the higher the electrification voltage, the stronger the ignition capacity of an iodine tungsten lamp and the greater the fire risk. For example, the surface temperature of an iodine tungsten lamp at 380V voltage is higher than that at 220V voltage, but if the voltage is too high, it will exceed the rated voltage of electrical lighting lamps, which will easily burn out and burst. Once the lamp bursts, the high temperature of its filament will ignite combustibles.Therefore, in use, it is necessary to keep away from combustibles such as fabrics, pine boards, and the like as far as possible according to the instructions, and avoid fire accidents by radiating heat.
