Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
As shown in fig. 1, an LED glass bulb air leakage detection device includes an LED glass bulb 1, a lamp cap 2 connected to the LED glass bulb 1, a temperature tester 3 for measuring a surface temperature of the LED glass bulb 1, and a probe 4 for detecting the surface temperature of the LED glass bulb 1;
the probe 3 tests at least the temperature at the top of the LED glass bulb 1.
1 bubble of LED glass is inclosed cell-shell structure, and its inside is equipped with the holding chamber for holding LED light source and radiating gas, wherein, in order to promote the life of radiating effect and LED bulb, radiating gas can include oxygen usually, like helium oxygen gas mixture etc. because oxygen is the gas of high ionization energy, whether leaks gas through traditional high frequency spark instrument detection, all has damage to LED light source and power.
The lamp holder 2 is connected with the LED glass bulb 1 and used for achieving mechanical connection and electrical connection of the LED bulb, the lamp holder can be a screw lamp holder or a bayonet lamp holder, and the type of the lamp holder is selected according to actual needs.
The probes 4 are connected with the temperature tester 3, the number of the probes is one or at least two, and specifically, the probes 4 are infrared probes. In this embodiment, the number of the probes 4 is one or more, when the number of the probes is one, the probes are used for detecting the temperature of the top of the LED glass bulb, if the LED glass bulb leaks air, the heat dissipation gas inside the LED glass bulb leaks out, so that the heat dissipation efficiency of the LED lamp is poor, and the top of the LED glass bulb is the highest temperature of the surface of the LED glass bulb, so that the temperature of the top of the non-leaking LED glass bulb is at least 10 ℃ lower than that of the top of the leaking LED glass bulb, and therefore, the temperature of the top of the LED glass bulb can be directly measured, so that whether the LED glass bulb leaks air or not can be determined.
Because the shape of LED glass bubble is different, whether leaks gas in order to judge LED glass bubble that can be more accurate, the utility model discloses need detect the temperature of LED glass bubble surface two places, judge according to the temperature difference and all leak gas, so in this embodiment, the quantity of probe is two, two the probe 4 detects respectively the temperature of the different positions in surface of LED glass bubble 1.
It should be noted that, because the heat dissipation gas inside the LED glass bulb 1 is a gas with high thermal conductivity and low viscosity, the temperature difference at each position of the surface of the LED glass bulb 1 is small through heat conduction and convection, and usually the temperature difference does not exceed 5 ℃, and the whole LED glass bulb 1 approaches a uniform temperature state. If the LED glass bulb 1 leaks air, air is mixed in the heat dissipation air, and the heat conductivity coefficient of the air in the LED glass bulb is low, the viscosity is high, and the temperature of the top of the LED glass bulb 1 is far higher than that of the side surface of the bulb shell, so the temperature difference is large, and usually the temperature difference exceeds 10 ℃.
Therefore, in order to better detect the temperature difference on the surface of the LED glass bulb 1, the two probes 4 are located at different positions of the LED glass bulb 1, that is, the vertical distances between the two probes 4 and the LED head 2 are not equal. Specifically, one probe 4 is located on top of the LED glass bulb and one probe 4 is located on the side of the LED glass bulb.

During detection, the two probes 4 positioned on the surface of the LED glass bulb 1 respectively detect the temperature, the temperature tester 3 displays the temperature detected by the two probes 4, and the temperature difference between the two probes 4 can be obtained to judge whether the LED glass bulb 1 leaks air or not.
In other embodiments, the number of probes 4 is one, wherein the relative position between the probes 4 and the LED glass bulb 1 is variable. Specifically, the probe 4 can move relative to the LED glass bulb 1, or the LED glass bulb 1 can move relative to the probe 4, and in the moving process, the vertical distance between the probe 4 and the lamp head 2 gradually increases or gradually decreases.
The surface of the LED glass bulb 1 comprises a first position and a second position, and the first position and the second position are not equal to the lamp holder 2 in vertical distance. More preferably, the first position is where the diameter of the LED glass bulb 1 is the largest, and the second position is where the vertical distance from the base 2 on the surface 1 of the LED glass bulb is the largest. The probe 4 detects the temperature at the first and second locations, respectively. .
During detection, the probe 4 firstly detects the first position temperature of the surface of the LED glass bulb 1, the temperature tester displays the temperature of the first position, the probe 4 and the LED glass bulb 1 move relatively, the probe 4 detects the second position temperature of the surface of the LED glass bulb, the temperature tester 3 displays the temperature of the second position, and therefore the temperature difference between the first position and the second position can be obtained, and whether the LED glass bulb 1 leaks air or not is judged.
In order to generate a temperature difference on the surface of the LED glass bulb 1, the lighting time of the LED lamp is at least 3 minutes, and the relative rest time of the probe 4 and the LED glass bulb 1 is at least 0.1 second, namely the time for the probe to detect the surface temperature of the LED glass bulb in the detection process is at least 0.1 second.
