Abstract
The utility model discloses a constant-temperature light source unit comprising a housing, a light source arranged inside the housing, a light exchange reflector, a window in the housing, a temperature sensor, a temperature controller and an electric heating element, wherein the temperature sensor and the electric heating element are arranged inside the housing; the temperature controller is arranged outside the housing, and respectively connected with the temperature sensor and the electric heating element; the temperature controller can be integrated with a control system of an optical spectrum instrument, and also can be independently arranged. The constant-temperature light source unit can quickly and accurately achieve a normal constant temperature state under the control of the temperature controller, so that the light source outputs stable energy within a short period of time. The constant-temperature light source unit can be directly upgraded and transformed on an existing light source unit, so that the machine without the characteristic does not need a relatively amount of cost when upgrading, the repeated investment is avoided, and existing equipment can fully play the efficiency.
Description
Technical field
The utility model belongs to experimental apparatus field, belongs to a kind of instrument system that uses thermal excitation continuous spectrum light source lamp, is specifically related to a kind of constant temperature light source cell.
Background technology
Use the instrument system of thermal excitation continuous spectrum light source lamp to be widely used in various instruments, use beam splitter to produce the spectrum of certain wavelength, bandwidth, by with testing sample and blank sample after the capacity volume variance that produces measure the active constituent content of testing sample.Use at present the instrument of this class illuminator all to have these problems below:
(1) much all consume in preheating with on the stabilization sub stage serviceable life of light source cell, fully do not send out brightness serviceable life.
(2) change of environment temperature is larger on the impact of light source cell, and the data that record under different time and condition will be considered the impact of different equilibration time and environment temperature in the time of comparison.
(3) light source is long preheating time, and temperature drift is large, needs long time just can reach stable.After start, all can not enter test mode within a short period of time, work efficiency is very low at every turn.
Utility model content
For the deficiency of background technology, the utility model provides a kind of constant temperature light source cell, and it utilizes independently temperature control system, makes light source reach fast temperature equilibrium, has shortened to a great extent the stabilization time of light source.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of constant temperature light source cell, comprises shell, be positioned at shell light source, change Light reflecting mirror, be positioned at shell
On window; Also comprise temperature sensor, temperature controller, electrical heating elements; Temperature sensor, electrical heating elements are all positioned at enclosure, and temperature controller is positioned at housing exterior; Temperature controller is connected with temperature sensor, electrical heating elements respectively.
Described electrical heating elements is evenly arranged in enclosure.
Described electrical heating elements adopts ptc heater.
When the utility model work, electrical heating elements preheats intensification to light source cell; Temperature sensor pair
The temperature of light source cell inside is carried out perception, and send temperature signal to temperature controller, temperature controller is controlled electrical heating elements heating or stops heating after receiving temperature signal, thereby makes the temperature of light source cell inside keep constant, keeps the energy stabilization of light source.Temperature controller can be integrated in instrumentation control system, and independently temperature controller also can be set, and temperature controller adopts existing equipment.Temperature sensor, temperature controller, electrical heating elements form independently temperature control system, can keep light source cell temperature constant fast, the temperature constant of light source cell can keep the output energy stabilization of light source, shortens greatly the pre-heat-stable time of instrument.
Compared with prior art, the utlity model has following advantage and beneficial effect:
1, the utility model, by independently temperature control system is set, makes light source cell reach exactly soon normal temperature constant state, thereby makes light source reach in the short period of time the stable of output energy.
2, the utility model can be on existing light source cell direct upgrading, make the type that does not possess this characteristic not need more expense in the time of upgrading, avoid overlapping investment, make existing equipment can give full play to usefulness.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1-temperature sensor, 2-change Light reflecting mirror, 3-light source, one, 4-shell, 5-window, 6-light source, two, 7-electrical heating elements, 8-temperature controller.
Embodiment
Below in conjunction with embodiment shown in the drawings, the utility model is described further.
As shown in Figure 1, the utility model comprises shell, be positioned at shell light source, change Light reflecting mirror, be positioned at
Window on shell; Also comprise temperature sensor, temperature controller, electrical heating elements; Temperature sensor, electrical heating elements are all positioned at enclosure, and temperature controller is positioned at housing exterior; Temperature controller is connected with temperature sensor, electrical heating elements respectively.Electrical heating elements is evenly arranged in enclosure.Electrical heating elements adopts ptc heater.
When the utility model work, electrical heating elements preheats intensification to light source cell; Temperature sensor pair
The temperature of light source cell inside is carried out perception, and send temperature signal to temperature controller, temperature controller is controlled electrical heating elements heating or stops heating after receiving temperature signal, thereby makes the temperature of light source cell inside keep constant, keeps the energy stabilization of light source.Temperature controller can be integrated in instrumentation control system, also can independently place, and temperature controller adopts existing equipment.Temperature sensor, temperature controller, electrical heating elements form independently temperature control system, can keep light source cell temperature constant fast, the temperature constant of light source cell can keep the output energy stabilization of light source, shortens greatly the pre-heat-stable time of instrument.
