Technical field
The invention belongs to classroom illumination technical field, it is related to the detection method and device and fluorescence of fluorescence lamp efficiency
The monitoring method of lamp.
Background technique
The classroom of school is the important place that student receives various knowledge educations, has sufficient light intensity not in classroom
It so that student is clearly seen that the content on blackboard and teacher can be allowed more easily to give lessons, and have research table
Bright, sufficient light can promote the raising of the eyesight, mood and brain effect of people, therefore construction one is good, is suitable for student
The classroom luminous environment that study and teacher give lessons is very important.
The foundation of luminous environment is usually the fluorescent lamp category low-pressure mercury discharging light by based on fluorescent lamp in classroom at present
Photoluminescence electric light source is mainly made of energy-saving fluorescent lamp and electric ballast (driving power source) two parts, the hair of fluorescent lamp
Ray machine reason is related to gas mercury discharge and two basic physical processes of luminescence generated by light, in starter ignition procedures, energy saving fluorescence
Fluorescent tube and electric ballast (driving power source) influence each other, interact, constitute fluorescent lamp shine etc. multinomial macroscopic view
Technical characteristic.
But in the case where energy-saving fluorescent lamp and electric ballast (driving power source) influence each other and interact, fluorescence
Lamp can not only generate the characteristics such as luminous, while can also generate light decay effect, and the light decay of fluorescent lamp is the hair in starter ignition procedures
A raw complicated quantitative change process in gas mercury discharge and two basic physical processes of luminescence generated by light, in this quantitative change
Cheng Zhong, a series of physical and chemical motion process in energy-saving fluorescent lamp interior microscopic field are internal cause, electric ballast (driving function
Rate source) electrology characteristic be external cause internal cause be it is leading, external cause is condition, and external cause is acted on by internal cause generation；And the light of fluorescent lamp
It declines, mostlys come from light decay, tube glass that light decay, the fluorescent powder powder that the miscellaneous phase impurity in energy-saving fluorescent lamp generates generate
Four aspects of light decay caused by light decay and electric ballast (driving power source) output characteristics of generation.
Good luminous environment is related with the illumination of fluorescent lamp in classroom, and illumination refers to that receive on unit area can
Light-exposed luminous flux, luminous flux refer to the sentient radiant power of human eye institute, it is equal to the radiation of a certain wave band in the unit time
The opposite product depending on seeing rate of energy and the wave band；Influence journey in view of glass light quality and roasted tube ventilation temperature to luminous flux
Degree is negligible, and fluorescent powder quality and dusting bisque quality can be affected to luminous flux, i.e. fluorescent powder quality and dusting
Bisque quality and the illumination of fluorescent lamp have direct relation；After long-time is using equipment, due to the quality and dusting of fluorescent powder
Bisque quality can decrease and aging, causes the light decay of fluorescent lamp stronger, so as to cause fluorescent lamp a period of time use
Later, equipment, which seems, normally lights, the illumination of actual fluorescent lamp weakens, and luminous environment is not up to standard, and due at this time
Apparent failure does not occur for equipment, and illumination monitoring system in the prior art also can not just make prompt and early warning in time,
And then lead to that indoor light intensity is taught actually possibly student can not to be enable to be clearly seen that the content on blackboard, to teacher
Give lessons and will also result in certain influence.
Therefore, study one kind can timing fluorescent lamp device detect and then can be not up to standard in fluorescent light flux
When make the detection method of fluorescence lamp efficiency of prompt and early warning and the monitoring method of device and fluorescent lamp in time and have
Highly important meaning.
Summary of the invention
The purpose of the present invention is overcome illumination monitoring system in the prior art that can not lead fluorescent light flux is not up to standard
The defect for making prompt and early warning when practical illumination deficiency in time is caused, the detection method and device of fluorescence lamp efficiency are proposed
And the monitoring method of fluorescent lamp passes through the operating status related data to equipment when obvious fault does not occur for non-equipment
Acquisition, determines whether equipment relevant parameter is up to standard, whether which can continue to using when fluorescent lamp or lighting apparatus luminous flux
Related early warning is given when not up to standard, and equipment is replaced.
In order to achieve the above objectives, the scheme that the present invention uses is as follows:
The detection method of fluorescence lamp efficiency is detected fluorescent lamp same position respectively and is worked as using identical test condition
Preceding illuminance value X and illuminance value A when not coming into operation, is calculated fluorescent lamp through formula K=X/A × 100% and shines
Efficiency K；
Illuminance value A when not coming into operation in the present invention is measured value, or theoretical standard value is theoretical standard
When value, entire detection process is more convenient, however, these are poor since different fluorescent lamps more or less has a certain difference
There is also certain differences by different illuminance value A when causing not come into operation, and illuminance value A when not coming into operation such as is theory
Standard value is easy to produce biggish error, thus illuminance value A when each fluorescent lamp does not come into operation is preferably by measuring
It arrives；
The test method of illuminance value are as follows: glimmering using the irradiation fluorescent lamp excitation of specific ultraviolet light in fluorescent lamp power-off
After light powder, the visible light that detection fluorescent powder issues after being excited generates illuminance value；
Wherein, the specific ultraviolet light shares two characteristic wavelengths of 165nm and 274nm, and respectively includes a section,
The section centered on each characteristic wavelength and with ± 20nm section；Fluorescent lamp is gas-discharge lamp, transparent by one
Glass lamp uniformly coats layer of fluorescent powder in tube wall, and both ends installation metal electrode simultaneously seals, and has conductive metal lamp base to draw
Out, it is vacuumized in pipe, pours into quantitative mercury, form steam, when two tip electrodes add voltage, and excite electricity in mercury vapour
Arc, under the action of electric arc, mercury vapour is inspired ultraviolet light and is radiated on the fluorescent powder of tube wall, the feature of the mercury vapour
Spectrum is 164 nanometers and 253.7 nanometers, wherein 253.7 nanometers of accounting is 80% or so, fluorescent powder mainly absorbs 253.7 and receives
Rice UV energy excites and generates visible light, forms illuminating effect to fluorescent tube external exposure；Since fluorescent powder can fully absorb
The ultraviolet light of 253.7nm, generate naked eyes it can be seen that light, therefore select wavelength be 165~274nm, intensity is 6000 microwatts
Ultraviolet light；
The angle of both luminous rays that the incident ray and fluorescent powder of specific ultraviolet light issue after being excited is less than 45
Degree.
Fluorescent lamp is for a long time in use, the luminous efficiency of the fluorescent powder in pipe can decay at any time.Usually by L70 in industry
(i.e. luminous flux decays to 70% from 100% when factory) is about set to the lifetime of fluorescent lamp, is commonly used for illumination on the market
The service life of fluorescent lamp is about 5000h, and due to factors such as light-emitting phosphor efficiency decaying, actual life can be lower than 5000.Work as light
The illuminating effect for being considered as fluorescent lamp when flux decline is to 70% cannot reach requirement.Due to fluorescent light flux decline
The main reason for be the decaying and loss of fluorescent powder, therefore be believed that and can be considered fluorescence to 70% in the luminous flux attenuation of fluorescent lamp
Powder has decayed to 70%.The summation for the visible light quantity that luminous flux is issued each second by illuminator, i.e. luminous flux.Unit of illuminance is
Lux is the luminous flux that illuminator is radiated on illuminated object unit area.When illuminating area is constant, luminous flux and illumination at
Direct ratio.So the variation of luminous flux can be measured with the variation of illuminance.

The structure of detection device of the invention is without being limited thereto, can also be another structure, the main distinction of two kinds of structures
It is whether contain ultraviolet rays emitting apparatus, the main difference in two kinds of structure uses is whether fluorescent lamp is powered, and contains ultraviolet light
The definition of light emitting device be it is active, can be used when closing fluorescent lamp ultraviolet light source (abbreviation active) to fluoresent coating into
Row irradiation, then the intensity of illumination after irradiation fluoresent coating is detected, it is analyzed by data, fluorescence lamp efficiency can be obtained, it is active
Device can be made into Handheld detection device, and application method is flexible；Definition without ultraviolet rays emitting apparatus be it is passive, can be

Ordinary circumstance selects 20mm grade, selects 10mm grades when reading lower, can obtain 4 times of sensitivity, detects spacing and is divided to two grades, and two
The strength relationship of person's Data Detection is four times, because of the illumination of area of illumination square being inversely proportional at a distance from luminous point, ultraviolet light
Be issued to measured point, the visible light returned from measured point, the actual range of light is twice, square four times of both relationships difference
(in Universal space, light intensity of the arbitrary point away from " point light source " is inversely proportional with square distance, and the present invention is ultraviolet to measured point transmission
Line, generates a distance, and measured point returns to visible light, then generates a distance, therefore twice of distance, then square is exactly four times
