Description
Technical field
Detection device and its detection side the present invention relates to detection device technical field, in especially a kind of fluorescent tube in miscellaneous gas
Method.
Background technique
Also there is not special equipment to be carried out test analysis at this stage in miscellaneous gas in finished product fluorescent tube, excessive miscellaneous gas contains
Amount, it is undesirable, cause fluorescent tube long-time burning point light decay big, early stage blackhead and service life short, it is serious or even electronics town can be fried
Device is flowed, causes whole lamp of serious failure.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide whether a kind of miscellaneous Gas content of fluorescent tube meets
It is required that fluorescent tube in miscellaneous gas detection device and its detection method.
The technical scheme of the present invention is realized as follows: in the detection device of miscellaneous gas in a kind of fluorescent tube, including for connecting
The lamp holder of fluorescent tube, the baking oven for being heated to fluorescent tube and the constant-current source for showing fluorescent tube pipe pressure, the lamp holder be located at baking oven it is interior and
It is electrically connected by electric wire with constant-current source.
It is preferred that are as follows: the baking oven is connected with the temperature heater for controlling oven temperature.
It is preferred that are as follows: the temperature heater is placed at the top of baking oven bottom or baking oven or baking oven two sides.
Another technical solution of the present invention is achieved in that a kind of detection side of interior detection device in miscellaneous gas of fluorescent tube
Method comprises the following steps that
1) fluorescent tube is packed into lamp holder, and lights fluorescent tube；
2) baking oven is opened, heats baking oven to fluorescent tube；
3) if in the section of temperature≤200 degree of baking oven, constant-current source shows pipe pressure >=300V of fluorescent tube, then fluorescent tube is determined
Inherent miscellaneous Gas content is more, is substandard products；If after 200 degree of the temperature > of baking oven, constant-current source shows that the pipe pressure of fluorescent tube is less than 300V,
Then determine that fluorescent tube is interior few in miscellaneous Gas content, is qualified product.
By using above-mentioned technical proposal, the invention has the following beneficial effects: the miscellaneous gas in fluorescent tube is mating again by baking oven heating
Constant-current source, according to the temperature value of the display of pipe pressure and baking oven on constant-current source, whether the next miscellaneous Gas content directly evaluated in fluorescent tube
It meets the requirements, judgement is not only directly but also accurate, short asks to solve big fluorescent tube long-time burning point light decay, early stage blackhead and service life
Topic.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention without any creative labor, may be used also for those of ordinary skill in the art
To obtain other drawings based on these drawings.
Fig. 1 is specific embodiment of the invention structural schematic diagram.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1, the invention discloses the detection devices in a kind of fluorescent tube in miscellaneous gas, including the lamp for connecting tube
Seat, the baking oven for heating to fluorescent tube and the constant-current source for showing fluorescent tube pipe pressure, the lamp holder are located in baking oven and pass through electric wire
It is electrically connected with constant-current source.
It is preferred that are as follows: the baking oven is connected with the temperature heater for controlling oven temperature.
It is preferred that are as follows: the temperature heater is placed at the top of baking oven bottom or baking oven or baking oven two sides.
Another technical solution of the present invention is achieved in that a kind of detection side of interior detection device in miscellaneous gas of fluorescent tube
Method comprises the following steps that
1) fluorescent tube is packed into lamp holder, and lights fluorescent tube；
2) baking oven is opened, heats baking oven to fluorescent tube；
3) if in the section of temperature≤200 degree of baking oven, constant-current source shows pipe pressure >=300V of fluorescent tube, then fluorescent tube is determined
Inherent miscellaneous Gas content is more, is substandard products；If after 200 degree of the temperature > of baking oven, constant-current source shows that the pipe pressure of fluorescent tube is less than 300V,
Then determine that fluorescent tube is interior few in miscellaneous Gas content, is qualified product.
By using above-mentioned technical proposal, the invention has the following beneficial effects: the miscellaneous gas in fluorescent tube is mating again by baking oven heating
Constant-current source, according to the temperature value of the display of pipe pressure and baking oven on constant-current source, whether the next miscellaneous Gas content directly evaluated in fluorescent tube
It meets the requirements, judgement is not only directly but also accurate, short asks to solve big fluorescent tube long-time burning point light decay, early stage blackhead and service life
Topic.
Following table be the corresponding light of different extinguishing temperature maintain, early stage blackhead and life situations:
One, summarize test situation
Two, 200 degree of temperature > for verifying baking oven, the not super alarming line (pipe pressure >=300V) of fluorescent tube pipe pressure, comparative test situation:
It can be obtained from a large amount of test data:
1, the vacuum state of fluorescent tube determines: (i.e. foreign gas can generate chemical reaction with tungsten wire and lead the atmosphere of energy-saving lamp
Early stage blackhead is caused to cause tungsten wire fracture of wire-failure simultaneously), while causing fluorescent tube light decay big and the lost of life.
2, when extinguishing temperature is in the case where 200 degree:
1), production equipment configuration is most reasonable, and vacuum state meets energy-saving lamp and is equipped with excessively high meeting using needs, such as vacuum plant
Cause cost increase uneconomical；
2), from key index Huang the black, service life, be able to satisfy market (client) needs in terms of light decay.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
