Abstract
The invention discloses a method for gas filling for an LED filament bulb. According to the method, a bulb shell of the LED filament bulb is inflated with heat conduction gas. During gas inflation, the temperature of the heat conduction gas is lower than the temperature of the surrounding environment, or the temperature of the bulb shell of the LED filament bulb is lower than the temperature of the surrounding environment. According to the LED filament bulb, gas inflation quantity in the bulb shell is increased by producing a certain low temperature gas inflation environment of which the temperature is lower than the temperature of the surrounding environment. In the method, the temperature of the heat conduction gas or the bulb shell of a LED filament lamp is lower than the temperature of the surrounding environment, in this way, during inflation of the heat conduction gas, the temperature of the heat conduction gas is also low, the density is high, accordingly the gas inflation quantity is also increased, thus the heat dissipation function of the LED filament bulb is improved, and the service life of the lamp is prolonged.
Description
Technical field
The present invention relates to field of lighting devices, the method for gas filled by a kind of LED filament bulb.
Background technology
At present, filament lamp is as an important development direction of LED illumination.The heat radiation of LED filament lamp without heat-conducting piece support,
Completely by filling the reasonable helium of a certain amount of heat conductivity or other heat-conducting gas to make the heat of LED strand spread out of,
Thus aeration quantity is a crucial heat conduction factor, and aeration quantity deficiency will cause LED spinline temperature too high so that it is be difficult to reach to have
Index, even has a strong impact on reliability so that product is difficult to promote the use of.
Summary of the invention
The problem existed for prior art, the present invention provides a kind of method that gas filled by LED filament bulb.The method
The aeration quantity of LED filament bulb, and then the heat sinking function of enhancement LED filament bulb can be significantly improved, extend the use longevity of light fixture
Life.
For achieving the above object, technical solution of the present invention is:
The method of gas filled by a kind of LED filament bulb, and the method is that heat-conducting gas is filled with the cell-shell of LED filament bulb
In；During inflation, the inflation ambient temperature of heat-conducting gas is less than ambient temperature.
The method of gas filled by a kind of LED filament bulb as above, and during inflation, the temperature of described heat-conducting gas is less than
Ambient temperature.
A kind of LED filament bulb as above fills the method for gas, during inflation, the cell-shell of described LED filament bulb
Temperature less than ambient temperature.
Having the beneficial effect that of technique scheme
It is by manufacturing certain low less than ambient temperature that LED filament bulb of the present invention improves the aeration quantity in cell-shell
Temperature inflation environment realizes.In the present invention so that the bulb temperature of heat-conducting gas or LED filament lamp is less than surrounding enviroment
Temperature, when so filling heat-conducting gas, the temperature of heat-conducting gas also can be relatively low, and density is relatively big, and aeration quantity improves the most accordingly, Jin Erzeng
Enter the heat sinking function of LED filament bulb, extend the service life of light fixture.
Detailed description of the invention
In order to make the technical problem to be solved, technical scheme and beneficial effect clearer, clear, below tie
Close embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain
The present invention, is not intended to limit the present invention.
Existing gas filling technology and equipment have two problems to make, and that aeration quantity is difficult to fill is a lot: problem one is equipment vacuum
Degree can not take out the original void gas in light LED filament Lamp bulb case completely；Problem two is that the cell-shell of LED filament bulb is in sealing
Will be with burning with during sealed-off, the temperature of cell-shell is higher, and when filling heat-conducting gas, the temperature of heat-conducting gas is the highest, density
The most relatively low, when so filling the heat-conducting gas of same pressure, aeration quantity is the most not.
In order to solve the problems referred to above, the method that the present invention uses is: manufactures certain and fills less than the low temperature of ambient temperature
Compression ring border.It is, during inflation, make the inflation ambient temperature of heat-conducting gas less than ambient temperature.
The temperature of heat-conducting gas that LED filament bulb of the present invention is filled, or the temperature of the cell-shell of LED filament bulb decides
The inflation ambient temperature of heat-conducting gas.
During inflation, LED filament bulb of the present invention can be filled with the heat-conducting gas less than ambient temperature, it is also possible to
During inflation, it is used below the cell-shell of the LED filament bulb of ambient temperature.Optimal, during inflation, will be less than surrounding enviroment temperature
The heat-conducting gas of degree is filled into less than in the cell-shell of the LED filament bulb of ambient temperature, to be greatly improved LED filament bulb
Aeration quantity.
Now as a example by the reasonable helium of heat conductivity, by specific examples below, the present invention is described.Wherein, embodiment
One is the method that gas filled by prior art LED lamp silk bulb, and embodiment two to four is that gas filled by LED filament bulb of the present invention
Method.
Embodiment one: fill gas technology by current LED filament bulb, test in 30 DEG C of ambient temperature, will
Temperature is also that the helium of 30 DEG C is filled with in the cell-shell of LED filament bulb.Substitute the bad for the good after gas, after waiting LED filament lamp to stablize one hour
Measuring inflation pressure, the inflation pressure in the cell-shell of the LED filament bulb measured is 0.91 atmospheric pressure.
Embodiment two: use the inventive method, test in 30 DEG C of ambient temperature, be the helium of 0 DEG C by temperature
It is filled with in the cell-shell of LED filament bulb.Substitute the bad for the good after gas, measure inflation pressure after waiting LED filament lamp to stablize one hour, measure
LED filament bulb cell-shell in inflation pressure be 1.01 atmospheric pressure, be greatly improved filling in the cell-shell of LED filament bulb
Tolerance.
Embodiment three: use the inventive method, test in 30 DEG C of ambient temperature, be also the helium of 30 DEG C by temperature
Gas is filled with in the cell-shell of LED filament bulb of 5 DEG C.Namely before inflation, first LED filament bulb housing temperature is dropped to 5 DEG C again
Inflation.Substitute the bad for the good after gas, after waiting LED filament lamp to stablize one hour, measure inflation pressure, the cell-shell of the LED filament bulb measured
Interior inflation pressure is 0.95 atmospheric pressure, and in the cell-shell of LED filament bulb, aeration quantity is improved.
Embodiment four: use the inventive method, test in 30 DEG C of ambient temperature, be the helium of 0 DEG C by temperature
It is filled with in the cell-shell of LED filament bulb of 5 DEG C.Substitute the bad for the good after gas, measure inflation pressure after waiting LED filament lamp to stablize one hour, survey
Inflation pressure in the cell-shell of the LED filament bulb measured is 1.04 atmospheric pressure, greatly improves the bubble of LED filament bulb
Aeration quantity in shell.
Described above illustrate and describes the preferred embodiments of the present invention, as previously mentioned, it should be understood that the present invention not office
Be limited to form disclosed herein, be not to be taken as the eliminating to other embodiments, and can be used for other combinations various, amendment and
