LED waterproof packaging structure and packaging process

Abstract

The invention discloses an LED waterproof packaging structure and packaging process in the technical field of LED waterproof packaging. The LED waterproof packaging structure comprises an LED lamp bead, a die bonding adhesive and a lens, wherein the LED lamp bead is fixedly connected to the upper surface of the die bonding adhesive. The LED waterproof packaging structure comprises a flat pressingmechanism, a carrier mechanism, a heat dissipation mechanism and a sealing mechanism, wherein the flat pressing mechanism is fixedly installed on the lower surface of the die bonding adhesive, the flat pressing mechanism is fixedly installed on the upper surface of the carrier mechanism, the heat dissipation mechanism is fixedly connected into the loading mechanism, the sealing mechanism is fixedly arranged between the heat dissipation mechanism and the carrier mechanism in a sleeving mode, and the lens is fixedly arranged on the upper surface of the carrier mechanism and located on the uppersides of the LED lamp bead. Along with the consensus of developing low-carbon economy globally and the functional advantages of the LED lighting industry in the fields of energy conservation and consumption reduction, an LED lamp on the current market adopts an integrated packaging form, colloid is aged and deteriorated after long-term use, the LED is not waterproof and poor in heat dissipation, and the LED waterproof packaging structure solves the problems of waterproofness and heat dissipation of the LED.

Description

technical field [0001] The invention relates to the field of LED waterproof packaging, in particular to an LED waterproof packaging structure and a packaging process. Background technique [0002] With the global consensus on the development of a low-carbon economy, the LED lighting industry has become an important new lighting source in the 21st century by virtue of its functional advantages in the field of energy saving and consumption reduction. Its application layout has also replaced many traditional light source application scenarios and is widely used It is used in various indications, displays, decorations, backlights, general lighting and urban scene lighting and other fields. In the development of LED lighting industry, field lighting has become a branch that develops rapidly. Using LED lamps as outdoor lighting fixtures means to ensure that the LEDs can work stably for a long time under harsh conditions in the field, so the waterproof technology of the lamps is e...

Problems solved by technology

[0005] The purpose of the present invention is to provide a LED waterproof packaging structure and packaging process to solve the problem that most of the LED lamp beads on the market are sealed by integral casting for waterproofing in the above-mentioned background technology, but the biggest problem of LED lights is heat dissipation, especially long-term lighting. The high-power LED lights that are used continuously for a long time, due to their high heat generation, the heat dissipation effect directly affects the service life of the lights. At present, most of the heat dissipation methods used by LED lights on the market are to use heat sinks to attach to the lamp holder. Direct convection heat dissipation with the air. Usually, when the LED lamp is used, it is mounted inside other electrical components. The air circulation is not good, and the surface of the lamp bead cannot be dissipated. The heat dissipation effect is negligible. The long-term high temperature makes the lamp bead yellow and dark. Finally, the life of the lamp bead is affected; a small part of the fan is installed inside the lamp body to directly dissipate heat from the aluminum alloy heat sink, resulting in an oversized structure of the LED lamp, poor practicality, and more power consumption during use; secondly, the above two heat dissipation methods lead to The waterproof effect of the LED light is poor, and the internal light source will slowly corrode and light decay after entering the water until the whole light is damaged
