Description
Technical field
The utility model is related to a kind of LED bulb, more particularly to the LED bulb that a kind of gas radiates.
Background technology
In the development process of LED, the test of LED light source temperature is extremely important when lamp works.Due to being dissipated using gas
LED/light source in the LED of heat is installed in be welded together by glass envelope shell-and-core post and formed in confined space, temp probe without
Method contacts progress thermometric with LED/light source in the case of ensureing sealedly through cell-shell.
Therefore, the method for test filament lamp LED temperature is mainly tested using voltage method at present.This method utilizes two
Pole pipe is under certain forward current, and the linear relationship between the forward voltage and PN junction temperature of PN junction is measured.This method
Topmost problem has at 3 points：
1. the temperature coefficient of different LED/light sources is incomplete same with batch, there is relatively large deviation during calculating.
2. the mean temperature of all chips of the temperature tested out.And we generally require the maximum temperature for testing out chip
Point, the data that voltage method is measured only have reference significance.
3. it is general to be calibrated using thermocouple during test temperature coefficient, due to others one can be introduced in test process
A little errors, the precision that it is tested is lower than thermocouple.
Utility model content
Technical problem underlying to be solved in the utility model is to provide a kind of LED bulb of gas radiating, is ensureing close
In the case of envelope, the data in cell-shell can be exported to outside cell-shell.
In order to solve above-mentioned technical problem, the utility model provides the LED bulb that a kind of gas radiates, and its feature exists
In including：Cell-shell, stem, LED/light source, lamp holder and drive circuit；
The cell-shell and stem surround seal cavity, and the LED/light source is suspended at the seal cavity by the stem
It is interior；The drive circuit is arranged in the cavity of lamp holder；Provided with electrically connecting leading for the LED/light source and drive circuit in the stem
Electrical filament；
It is additionally provided with the stem inside connection cell-shell and the signal wire outside cell-shell.
In a preferred embodiment：The signal wire is thermocouple wire.
In a preferred embodiment：The signal wire is parallel to each other with conductive filament, and is arranged in a linear.
In order to solve above-mentioned technical problem, the utility model possesses following beneficial effect：
A kind of LED bulb for gas radiating that the utility model is provided, in stem portion there is provided signal wire, signal wire
One end is placed in cell-shell by stem, and the other end is placed in outside cell-shell.So signal wire just can be before cell-shell sealing be ensured
Put, the useful data in cell-shell are exported to outside cell-shell.Such as, it is necessary to when measuring the operating temperature of LED/light source in cell-shell,
Signal wire uses thermocouple wire, and its one end is contacted with LED/light source, and the other end is contacted with thermocouple probe, and this makes it possible to use
Thermocouple probe is accurately read the operating temperature of LED/light source, and compared to traditional voltage method, the measurement accuracy of thermocouple is significantly
Improve.

In vivo；The drive circuit is arranged in the cavity of lamp holder；Provided with the electrical connection LED/light source and drive circuit in the stem 1
Conductive filament 11；
It is additionally provided with the stem 1 inside connection cell-shell and the signal wire 12 outside cell-shell.
In the present embodiment, the signal wire 12 is thermocouple wire.The signal wire 12 is parallel to each other with conductive filament 11, and is in
It is arranged in a straight line.
A kind of LED bulb of above-mentioned gas radiating, signal wire 12 is provided with the part of stem 1, and one end of signal wire 1 leads to
Cross stem 1 to be placed in cell-shell, the other end is placed in outside cell-shell.So signal wire 12 can just ensure the premise of cell-shell sealing
Under, the useful data in cell-shell are exported to outside cell-shell.Such as, it is necessary to when measuring the operating temperature of LED/light source in cell-shell, believe
Number line 12 uses thermocouple wire, and its one end is contacted with LED/light source, and the other end is contacted with thermocouple probe, and this makes it possible to use
Thermocouple probe is accurately read the operating temperature of LED/light source, and compared to traditional voltage method, the measurement accuracy of thermocouple is significantly
Improve.
If necessary to gather during other data in cell-shell, from the signal wire of respective type.
It is described above, only the utility model preferably embodiment, but protection domain of the present utility model is not
This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model is disclosed
Change or replacement, should all cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should
It is defined by scope of the claims.
