Description

The invention relates to a method and apparatus for automatic measurement of electrical and light parameters electric lamps, especially discharge lamps.

A known method of measuring electrical and light parameters electric lamps, such as: supply voltage, lamp voltage, lamp current, lamp active power and flux The light change is based on the fact that the measured lamp turns on in a holder in the photometric chamber and is supplied with voltage for the time necessary to stabilize the parameters, Durable for incandescent lamps up to 5 minutes, and for discharge lamps up to 15 minutes. Then the measurements above are made one by one parameters listed using the instrumentation measuring. After completing the measurements, the measured lamp is twisted out of the lampholder and inserted in its place stepna and the measuring process is repeated.

Known automated measuring sets include the photometric chamber in which the holder is mounted connected to a digital voltmeter and a printer and a battery pack steering pit. Measurements of electrical parameters and lights with the possibility of printing are performed automatically in a fixed order and the process is controlled from the control panel.

The main disadvantage of the known solutions is the low efficiency measuring devices resulting from the need to display of each measured lamp for the period necessary to stabilization of its parameters, which causes inefficiency cheap handling during these periods. Therefore, well-known companies lighting systems, e.g. by Osram, has developed and installed in one room, the nine described sets measuring instruments intended for light bulb photometry.

Each set operated by one person is watered connected via the measuring path to the common electronic a calculator that performs power and efficiency conversion light from parameters measured in the bulb circuit, The bulbs are placed in the socket of each station in turn measurement set and after stabilization of parameters and the connection with the calculator is done by it measurement. The measured bulb is removed from the socket and inserted next. This solution allows for a significant increase the number of lamps measured over a certain period of time. It requires however, large areas needed to be installed the aforementioned measuring groups, a significant number handling and, moreover, it is expensive due to the large amount photometric chambers, desktops and printers. In case of adaptation of this solution to measurements of discharge lamps additionally, one should take into account incomplete use cheap service in 15-minute heating periods lamp. ^ The object of the invention is to avoid drawbacks and inconveniences known solutions. especially increasing efficiency measuring lamps with simultaneous replacement of several bits measuring joints with one device of significantly smaller dimensions, This goal is achieved by developing a method and an apparatus for automatic measurement of electrical parameters and electric light lamps such as: voltage supply voltage, lamp voltage, lamp current, lamp active power, luminous flux, with the possibility of printing the obtained results.

The Sp team, in turn, automatically switches the two-position one switch 7 to the second position II, which makes the lamp L at the measuring position P is supplied with the voltage ze Ua source stabilized by a gland To reference you. At the time of switching the L lamp power supply in the chamber tube, the lamp supply L is closed via resistor R bypass choke For reference and dual position switch 7, which ensures continuous lighting lamps L. At the same time, the switching unit SP is connected outputs of measuring points of the measured lamp L for a 6-measuring system. Measurements of L lamps parameters na P measurement positions are performed by a 6-digit system measurement controlled from the K commutator output. Converters Pu P2 »P3 of the ZP set of transducers in the measuring system 6 They are controlled directly from the generator output G. and they work cyclically.

The measuring cycle consists of two measures. In first tact, the effective alternating values of the property are processed displayed parameters, which are recorded after processing in the analog memory, and in the second measure in the same The tracks are converted into reference voltages and voltage values After processing, the method is compared compensation with the values recorded in the first tact. After the end of the measuring cycle, the K commutator activates relays N15 N3 ... N5 in the programmed sequentially, it enables the voltmeter Vc cy¬ in each case frowy, which measures the value of the parameter and starts the second neck DR. Measured lamp L at the measurement position P after opening the photometric chamber 3, it moves to Wi * position where it is removed from the holder via pressing the arm 17 of the angle lever against the body 10 frame, which causes the movable half ring to tilt 16 from the lamp base L to a distance that allows free removing the lamp from holder 2 without having to twist it.

Another lamp and action are placed in the released position costs related to the automatic measurement of its parameters keep repeating.
