Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0041] Such as figure 1 , figure 2 In the shown embodiment, a waterproof LED lamp includes a housing 1, an LED lamp board 2 and a heat sink 3 arranged in the housing, and an electronic sealant can be coated on the LED lamp board, wherein the housing includes a two A cylindrical light-transmitting body 11 with an open end and end caps 12 sealed at both ends of the light-transmitting body. The end cap and the light-transmitting body are fixedly connected by a sealant. The light-transmitting body can be made of PC plastic to make it It has sufficient strength and high light transmission performance. The light-transmitting body includes a straight bottom wall 111, which is beneficial to the installation and positioning of the lamp when in use. The two sides of the bottom wall are connected with the two sides of a superior arc column wall 112. Th...

Abstract

The invention discloses a waterproof LED lamp and a sealing method. A shell of the waterproof LED lamp comprises a cylindrical body pervious to light and end covers at the two ends, ventilation holes are formed in the end covers, the surface of an LED lamp panel is coated with electronic moisture-proof glue firstly during packaging, then the space between each end cover and the body pervious to light is filled with a sealant, gas generated due to volatilization of the sealant during solidification is discharged step by step through the ventilation holes in the end covers, each ventilation hole is filled with a sealant at the moment and is blocked through a sealing body, and the ventilation holes can be sealed after the sealant in the ventilation holes is solidified completely. According to the waterproof LED lamp and the sealing method, the problem that the shell is cracked when the waterproof LED lamp is used can be effectively solved, and the waterproof grade of the waterproof LED lamp can be improved remarkably.

Description

technical field [0001] The invention relates to a lamp, in particular to a waterproof LED lamp and a corresponding packaging method thereof. [0002] Background technique [0003] At present, LED lamps with good energy-saving effects are gradually being promoted. LED lamps usually include LED light boards, heat sinks arranged on the back of the LED light boards, bottom shells for installing LED light boards and heat sinks, and covers on the bottom shells. transparent cover. When LED lamps need to be installed in wet or fish tanks and other watery environments, they need to have a corresponding waterproof level. At present, the conventional method is to install a waterproof coating on the surface of the LED lamp board, and at the same time to install a waterproof coating on the light-transmitting cover and bottom shell. Set the sealing ring at the joint. [0004] For example, a "waterproof LED light bar" disclosed in the Chinese patent literature, the notification number i...
