Three-channel electrode-sharing light-emitting diode (LED) lamp of lens structure

Abstract

The invention relates to a three-channel electrode-sharing light-emitting diode (LED) lamp of a lens structure, which is moisture-proof and waterproof, is added with lenses and can solve problems that the existing surface mount device (SMD) LED lamp absorbs water and moisture easily and lamp failure is caused due to the fact that the existing SMD LED lamp adopts a phenyl-propanolamine (PPA) material base. The LED lamp comprises a plurality of pins and a plurality of light-emitting chips. Each pin comprises a pin main body, the upper end of each pin main body bends to form a pad portion, the lower end of each pin main body bends to form a surface mounting portion, the light-emitting chips are arranged on the pad portions of the pins, lens are formed on the pins in injection molding mode, the pin main bodies and the pad portions are embedded in the lenses in sealing mode, and the surface mounting portions extend out of the lenses. The three-channel electrode-sharing LED lamp has the advantages of solving the problem of moisture and water absorbing and being capable of being used outdoors completely; and being capable of using a power supply flexibly by adopting the three-channel electrode-sharing structure. The pins are flat and elongated so that the pins have conductive functions and good radiating characteristics. The lower ends of the pin main bodies turn up to form the surface mounting portions so that characteristics of patches of the SMD LED lamp is reserved and surface mounting of the LED lamp is facilitated.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a moisture-proof and waterproof LED lamp with a lens-added three-channel common-polar lens structure. Background technique [0002] Because the traditional SMD LED is based on PPA material, the material is easy to absorb moisture and water, and the adhesion with the potting glue is not very good, resulting in poor air tightness, which is easy to cause the SMD LED to fail due to moisture. After that, it will lead to the dead light of SMD LED. At present, most of the dead light of SMD LED on the market is caused by the dampness of SMD LED, so it is difficult for SMD LED to go outdoors. [0003] For example, the authorization announcement number is CN201562691U, and the name is a Chinese utility model patent for a full-color SMD LED, which includes a bracket, a chip, and a gold wire. The gold wire connects the PPA plastic plate and the chip of the bracket. The surface of the PPA plastic plate is provi...

Problems solved by technology

[0004] The present invention mainly solves the problem that the existing SMD LED lamp adopts PPA material base, which is easy to absorb water and moisture and lead to dead lights, and provides a moisture-proof and waterproof LED lamp with a three-channel common-polar lens structure and a lens.

The LED lamp of the present invention removes the base part of the traditional PPA material, and adopts the lens of the in-line LED, only the lens and the pin are bonded, so that the lens and the pin retain the good adhesion of the in-line package, solving the problem of It solves the problem of traditional SMDLED absorbing moisture and water. In addition, the mounting part formed at the lower end of the pins in the present invention retains the characteristics of the SMDLED lamp patch and can be easily installed.
