Abstract
The invention provides a high-stability constant-current deuterium lamp power supply which comprises a power supply, a deuterium lamp, a preheating system, a time delay circuit and a sampler. The power supply is a complete machine power supply for providing high voltage, medium voltage and low voltage needed. The complete machine power supply is connected with a medium-voltage power supply, a high-voltage trigger power supply and a regulated power supply. The medium-voltage power supply and the high-voltage trigger power supply are connected with a power supply switching device. The power supply switching device and the preheating system are connected with the deuterium lamp. The time delay circuit is connected with the preheating system and the power supply switching device. The regulated power supply is connected with the preheating system through a reference power supply, a control front stage and a current driver. The sampler samples the current driver and feeds the sampling result back to the control front stage to form a loop. Compared with the prior art, the high-stability constant-current deuterium lamp power supply of the invention has the following significant advantage and beneficial effect: the size is small, the efficiency is high, the current of the deuterium lamp is highly stable, and the noise is low; and after error-free circuit welding, bias stability reaches 0.1 directly without adjustment.
Description
Technical field
The present invention relates to optical instrument field is and in particular to a kind of be used for ultraviolet-uisible spectrophotometer light source power supply system
High stability constant current Power supply for deuterium lamp.
Background technology
Deuterium lamp is the ultraviolet source ideal for photometric analysis apparatus, in biochemical analyzer, widely uses.Its
Spectrum is continuous, wavelength 190nm～400nm.The intelligent Power supply for deuterium lamp of commercialization at present is mainly by external import, expensive.Deuterium
Lamp power supply is more complicated, needs to filament pre-heating and build-up of luminance.After build-up of luminance, keep 70v～80v's between deuterium lamp anode and negative electrode
Voltage, such deuterium lamp just can be lighted, and sends ultraviolet light.In order to maintain the stability of deuterium lamp brightness, and the longevity extending deuterium lamp
Life, after build-up of luminance, deuterium lamp should maintain the high-precision current of 300ma, existing constant-current power supply circuit poor reliability, and efficiency is low, surely
Fixed degree is not high.
Content of the invention
Problem to be solved by this invention is to overcome the deficiencies in the prior art, provides a kind of high stability constant current deuterium lamp electricity
Source.
The present invention solves its technical problem and takes technical scheme below to realize:
A kind of high stability constant current Power supply for deuterium lamp, including power supply, deuterium lamp, pre-heating system, delay circuit and sampler；Described
Power supply be the whole machine power supply that required high pressure, middle pressure, low pressure are provided；Whole machine power supply and middle voltage source, height
Pressure triggering power supply, regulated power supply are connected；Described middle voltage source, high pressure triggering power supply are all connected with power switching device, for TURP
Parallel operation is all connected with deuterium lamp with pre-heating system；Described delay circuit is connected with pre-heating system and power switching device respectively；Described
Regulated power supply through reference power supply, control prime, electric current drive be connected with pre-heating system；Sampler is to current driver using simultaneously
Feed back to control prime, form loop.
The present invention compared with prior art has significant advantage and beneficial effect: there is small volume, efficiency high, deuterium lamp
Current stability is high, and noise is low；Circuit welding errorless after need not adjust directly reach 0.1% draw inclined degree of stability, purposes is wider,
The UV-detector that can be used in performance requirement higher single beam ultraviolet spectrophotometer and Liquid apparatus is powered.
Brief description
Fig. 1 is the structural representation of the present invention.
Specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to the specific embodiment providing according to the present invention, structure, feature and its
Effect, after describing in detail such as.
A kind of high stability constant current Power supply for deuterium lamp as shown in Figure 1, including power supply, deuterium lamp, pre-heating system, time delay electricity
Road and sampler；Described power supply is for providing the whole machine power supply of required high pressure, middle pressure, low pressure；Whole machine is powered electricity
Power supply is triggered with middle voltage source, high pressure in source, regulated power supply is connected；Described middle voltage source, high pressure triggering power supply all with supply TURP
Parallel operation is connected, and power switching device is all connected with deuterium lamp with pre-heating system；Described delay circuit respectively with pre-heating system and power supply
Switch is connected；Described regulated power supply is driven and is connected with pre-heating system through reference power supply, control prime, electric current；Sampler pair
Current driver using and feed back to control prime, form loop.
Above one embodiment of the present of invention is described in detail, but described content has been only the preferable enforcement of the present invention
Example is it is impossible to be considered the practical range for limiting the present invention.All impartial changes made according to the present patent application scope and improvement
Deng all should still belong within the patent covering scope of the present invention.
