Ultraviolet high-pressure mercury lamps (also called uv lamps, the same below) and self-ballasted high-pressure mercury lamps are widely used in industrial and mining enterprises as ultraviolet flaw detection lamps, ultraviolet curing lamps, ultraviolet Observation light, surface inspection light.

Ultraviolet light bulbs refer to the luminous spectrum range of 350nm-400nm, the main peak is 365nm, suitable for testing materials and products, through the change of weather conditions such as strong ultraviolet rays in the aging box, test the aging phenomenon and The degree of discoloration, fading and other phenomena can be obtained in a short period of time. The UV lamp has high power, strong ultraviolet penetration, and minimal harm to skin and human body.

Strong ultraviolet high pressure mercury lamp: The light source used in UV equipment used in industry is mainly a gas discharge lamp (mercury lamp). According to the pressure of the gas in the lamp cavity, it is divided into low pressure, medium pressure, high pressure and ultra-high pressure. High-pressure mercury lamps are usually used for industrial production and curing (in the hot state, the pressure in the cavity is 0.1-0.5/MPa). The high-pressure mercury lamp can produce characteristic ultraviolet (UV), visible and infrared (IR) light with wavelengths of 310nm, 365nm, and 410nm with strong radiation. The so-called "UV lamp" refers to a 365nm high-pressure mercury lamp)

How to test the quality of UV uv lamp

For ultraviolet high-pressure mercury lamps and self-ballasted mercury lamps, a multimeter cannot be used to check, but an ordinary megohmmeter can be used to check.

The inspection steps for the quality of the UV bulb high-pressure mercury lamp bulb:

Take a 1000V megohmmeter or a 5000v high-voltage megohmmeter (insulation shaker), clamp the megohmmeter test leads on the two electrodes of the ultraviolet high-pressure mercury bulb, and shake the insulating shaker, such as ultraviolet high-pressure mercury lamp or self-ballasted mercury If there is a weak discharge and luminous phenomenon between the two poles of the light-emitting tube inside the bulb, it means that there is no air leakage in the inner tube of the bulb, and the tube is good and can be used continuously. Note that due to the damage to human eyes and skin due to ultraviolet rays, please be sure to wear ultraviolet protective glasses when operating.

Precautions for warehouse storage of UV light bulbs high pressure mercury light bulbs:

Store in a cool place and seal, avoid direct sunlight.

Precautions for the use of high pressure mercury lamp bulbs UV bulbs:

Transformers and capacitors of corresponding specifications must be equipped when using. The surface of the lamp tube must be wiped clean with absolute ethanol before use, and it is strictly forbidden to touch it directly. This UV bulb produces intense long-wave violet radiation (main line 365 nanometers) from a high-pressure mercury vapor discharge. Strong ultraviolet rays can burn eyes and skin, so avoid direct exposure to light during use; the ultraviolet light bulb is accidentally damaged, resulting in the release of mercury vapor, on-site personnel must leave immediately, and let the site continue to ventilate for 20-30 minutes to prevent mercury vapor from being inhaled into the body. lead to poisoning; clean up the site in time when it is safe, and the recovered mercury raw materials can be reserved for experiments. (If the lamp tube is broken in the sealed UV curing machine, because there is a fan on the lampshade for cooling, it can be opened to the outside, so it is generally not harmful to the UV machine operator)
