Description

Technical Field

[0001] The present invention relates to the technical field of lamps, and in particular to a lamp structure comprising an air getter block. Background Art

[0002] In LED lamps, organic volatile gases may cause certain damage to LEDs and transparent plastic parts, such as causing the LED to turn black, and the transparent plastic cover to turn yellow or atomize. Especially for closed lamps with waterproof and dustproof requirements, the paint on the light board in the LED light source cavity, the rosin of the solder joints, the thermal grease or other organic gases produced by the glue used for sealing and bonding are difficult to diffuse outside the lamp, and there are a lot of residues in the light source cavity, which may cause certain damage to transparent plastic parts and LEDs. Generally, static volatilization is adopted. Before sealing the light source cavity, let the light source cavity stand for a period of time to allow various glues to solidify and let the organic gases evaporate as much as possible at this stage, or at the same time, it is necessary to clean the rosin of the solder joints to keep the LED light board as clean as possible and reduce the source of organic volatiles.

[0003] However, the use of static volatilization or cleaning of the light source cavity is, on the one hand, a complex process, which increases production time and labor, reduces production efficiency, and prolongs the production cycle. On the other hand, static volatilization or cleaning of the light source cavity, from the actual application results, cannot completely guarantee that there is no organic volatile gas in the light source cavity. It is only through static volatilization or cleaning that the organic volatile gas is reduced. However, as time goes by, the organic volatile gas accumulated in the light source cavity may still cause certain damage to the LED light source or the transparent plastic cover.
