In the related art, as an outdoor lamp, it is indeed necessary to withstand various severe weather conditions, especially the invasion and disturbance of rainwater, so the waterproof performance of the light emitting module of the mowing lamp is an important aspect in the design thereof. The light emitting module of the mowing lamp is mostly an LED lamp bead, the LED lamp bead is also called a high color gamut CSP (Chi p Sca l e Package) lamp bead, and the high color gamut CSP (Chip Sca l e Package) lamp bead has a compact structure because the packaging size is close to the chip size, so that more attention is usually required to be paid to protective measures in design and material selection, especially moisture invasion prevention, so that stable operation of the mowing lamp in a complex environment is ensured. Because the surface area and the volume ratio are relatively large, the CSP lamp bead is easy to be influenced by high temperature and high humidity, and particularly in the aspect of water vapor sensitivity, if the sealing performance of the CSP lamp bead is insufficient, under the high temperature and high humidity environment, moisture is easier to penetrate into the package, so that the luminous efficiency is reduced, chemical reactions of internal materials, such as lead frames and bracket coating oxidation, can be caused, even electrical short circuit is caused between a chip and the package material, and the performance and the reliability of the CSP lamp bead are seriously influenced.
