[0045] In other embodiments, the desiccant 8 and the oxygen enhancer 7 can also be used in combination.
[0046] The LED glass lamp provided by the present invention ensures that the oxygen content inside the accommodating chamber 6 is always within the preset range through the setting of the oxygen enhancer 7, which solves the difficulty in balancing the oxygen and helium in the heat dissipation gas of the traditional LED bulb lamp The problem of prolonging the service life of the LED glass lamp; through the setting of the desiccant 7, the water vapor inside the accommodating cavity 6 is absorbed to prevent excessive water vapor content from affecting the service life of the LED glass lamp.

The present invention relates to the field of lighting technology, in particular to an LED glass lamp, which includes a lamp base, a shell connected to the lamp base, a stem located inside the shell, an LED light source installed on the stem, and the lamp. A power supply connected to the LED light source; the shell and the stem are hermetically connected to each other, and an airtight accommodating cavity is formed inside the shell, and a heat-dissipating protective gas and an oxygenating agent are also arranged in the accommodating cavity. The LED glass lamp provided by the present invention ensures that the oxygen content inside the accommodating cavity is always within the preset range through the setting of the oxygen enhancer, which solves the problem that the oxygen and helium in the heat dissipation gas of the traditional LED bulb lamp are difficult to balance , prolong the service life of the LED glass lamp.
Description
technical field [0001] The invention relates to the technical field of LED lighting, in particular to an LED glass lamp. Background technique [0002] LED glass lamp combines the advantages of traditional lighting and LED. It has the advantages of full-angle light, no yellowing and deformation, wide light-emitting surface, good heat dissipation, and high production efficiency. It is very popular among customers. Because it needs to improve the heat dissipation effect, it is generally filled with helium or a mixed gas of helium+oxygen, and a mixed gas of helium+oxygen is preferably used. [0003] LED glass lamps are air-tight lamps, and there are inevitably small organic molecule pollutants inside them. These pollutants may come from LED packaging materials, substrate materials, solder materials, gas impurities, etc. The existence of pollutants will affect the performance of LED glass lamps. service life. Therefore, it is necessary to avoid the use of materials that are pro...
