UVC LED is a linear light source with an internal micro lens and an irradiation angle of about 60 °. It does not belong to the lamp series, but to the electronic product series. Whether UV LED needs to be connected to a ballast depends mainly on the specific type and design requirements of the UV LED lamp.

Generally, for common UV lamps such as low-pressure mercury lamps and low-pressure xenon lamps, due to their working voltage not being consistent with the usual household voltage, ballasts need to be installed to adjust the current frequency and amplitude, so that the lamp can work stably and extend its service life. The ballast plays a role in limiting current and generating instantaneous high voltage here, which helps to ensure the normal start-up and stable operation of the lamp.

However, for UV LED lamps, the situation may be different. Due to the fact that the operating voltage range of UV LED lamps is usually consistent with household voltage, some UV LED lamps can be used directly without the need to install ballasts. But this is not absolute, as the design and manufacturing of UV LED lamps may vary by brand and model, and some UV LED lamps may still require ballasts to ensure their stable operation. Especially when UV LED lamps are used for specific applications such as curing, disinfection, etc., more precise current and voltage control may be required, making the role of ballasts particularly important.

In addition, even though some UV LED lamps do not require ballasts, attention should still be paid to the stability of current and voltage in practical use to ensure the normal operation and service life of the lamp tube. Therefore, when selecting and using UV LED lamps, it is recommended to refer to specific product manuals or consult the manufacturer for more accurate information.

In summary, whether UV LED needs to be connected to a ballast depends on the specific type of lamp tube and design requirements. In most cases, if the operating voltage of UV LED lamps is consistent with household voltage and the design is reasonable, it may not be necessary to install ballasts. However, in order to ensure the stable operation and service life of the lamp tube, attention should still be paid to the stability of current and voltage, and professional opinions should be consulted when necessary.
