1. Purpose of lamps

Mercury-quartz lamps are powerful sources of ultraviolet radiation and are used in medicine (for physiotherapy purposes), biology and technology, photochemical processes, luminescent analysis, etc.

Inclusion of lamps in the alternating current network.

UV lamps. Reference data

Л - DRT lamp
Db - throttle
К - button
С1 -capacitor
С2 capacity 2-3 µF. for example 300-600 V
С2 - capacitor 0,0003 -0,0005 µF.

2. Specifications of lamps

Mercury-quartz lamps are designed for operation in AC networks with a voltage of 220V, a frequency of 50Hz, ballasts in accordance with GOST 16809-71.

During the first 10-15 minutes. after turning on the lamp, its electrical parameters change (unsteady mode), and then remain constant (steady state) at a constant mains voltage (see Table 1). The dimensions of the lamps are shown in Fig. 1 (DRT230), devil 2 (DRT400) and devil 3 (DRT1000)

Light fluxes of DRT type lamps in the wave range 240-320 nm

3. Instructions for the use of lamps

Before installing the lamp in the equipment, it is recommended to wipe it with cotton wool moistened with alcohol.
When using lamps in closed apparatus, adequate ventilation must be provided.
It is possible to operate lamps only with devices that provide starting and steady state, indicated in tab. one.
The position of the lamp during operation is horizontal, with a deviation from the horizontal in both directions by an angle of no more than 10.

4. Precautions when working with lamps

To protect your eyes from ultraviolet radiation, you must wear safety glasses.
Lamps for physiotherapy should be used under the supervision of medical personnel.
When using lamps for other purposes, precautions should be taken to avoid burns from the lamp's ultraviolet rays.
Lamps that have failed or have expired should be broken into a closed area and treated with 1 percent. solution of potassium permanganate, take it outside the populated area and bury it in the ground to a depth of at least 0,3 m.

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

The neck is the weak point of a football player 07.05.2005

Sports doctors from Ankara (Turkey) examined the cervical vertebrae of football players and people of the same age who do not play football on x-rays. Result: leather ball knights have a cervical spine that looks 10-20 years older than non-football players.

According to the authors of the study, the reason is that players often take the ball on their heads, and the impact force at the same time reaches 200 kilograms.
