AI Technical Summary
Technical Problem
The existing floodlights have metal sleeves at the wire holes, which increases costs and is not conducive to the balance of air pressure inside and outside the lamp, affecting processing efficiency and waterproof performance.
Method used
The design combines a plastic connector with a potting sealant layer. A plastic connector is installed at the wire penetration point and sealed with potting sealant. A small hole is provided at the closed end of the shaft hole to release hot air, and the small hole is filled with a potting sealant layer for sealing.
Benefits of technology
It reduces processing costs, improves connection stability and waterproof performance, balances internal and external air pressure, and ensures product applicability and consistency.

Abstract
The utility model discloses a novel project lamp structure which comprises a lamp body shell, a light source plate and a glass panel, the light source plate and the glass panel are fixed in the lamp body shell, shaft holes with closed inner side ends are formed in the symmetrical outer walls of the lamp body shell, a U-shaped support is arranged on the lamp body shell, and the two ends of the U-shaped support are rotatably connected in the shaft holes through shaft bodies. A wire penetrating hole is formed in the lamp body shell, a plastic connector is connected to the wire penetrating hole in a threaded mode, an electric wire of the light source plate penetrates through the plastic connector, a small hole used for discharging hot air in the lamp body is formed in the closed end of the shaft hole, and after the lamp body shell is machined, the small hole is filled with a glue pouring blocking layer for sealing. The LED lamp is reasonable in structural arrangement, facilitates reduction of machining cost, is further provided with the small holes, can discharge hot air in the lamp body in the production process, balances internal and external air pressure, facilitates guarantee of machining effectiveness and stability, is sealed by filling the small holes with the glue filling sealing layers after aging, and improves production efficiency. And internal hot gas is prevented from overflowing from the panel sealant to generate a water leakage gap.
