Description

Technical Field

[0001] The utility model belongs to the technical field of LED lamps, and in particular relates to a waterproof LED lamp for a signboard light box. Background Art

[0002] Signboard light box LED tubes are LED tubes designed and used specifically for signboard light boxes. LED tubes, also often called LED light tubes or LED fluorescent tubes, use LED (light-emitting diodes) as their light source. Compared with traditional fluorescent tubes, LED tubes have many advantages, such as higher luminous efficiency, longer service life, lower energy consumption and better environmental performance.

[0003] Existing outdoor signage tubes on the market lack waterproof properties due to their G13 connection pins. While they have a cover for waterproofing, the effectiveness is limited. Water can still seep in over extended periods of use, potentially causing a short circuit or fire, shortening the lifespan. To address this issue, we propose a waterproof LED tube for signage light boxes. Utility Model Content
