Description

Freezer Waterproof Lighting Fixtures

technical field

The utility model relates to a lamp, in particular to an LED lamp suitable for a refrigerator.

Background technique

Compared with traditional light sources, LED is a luminous body with high luminous efficiency, low radiation, low power consumption, long life, low driving voltage, fast start-up, and environmental protection. Fluorescent lamp technology with LED as light source is developing rapidly. For example, Chinese patent 101839413A discloses a LED fluorescent lamp, which includes a heat dissipation base, a lampshade and a light source substrate fixed on the heat dissipation base, a driving circuit, and a power connector installed at the end of the heat dissipation base and the lampshade. A plurality of light emitting diodes are installed, and the drive circuit is arranged inside the heat dissipation base. The light source substrate includes at least two sub-light source substrates. Different lighting directions of light-emitting diodes can increase the light distribution area and lighting angle of LED fluorescent lamps.

The waterproofing of the end cover of the existing waterproof lamp tube is to arrange a piece of waterproof gasket between the end cover and the end of the lamp tube, and use the end cover to press the waterproof gasket to achieve the purpose of waterproofing the lamp tube. This kind of waterproof design is troublesome to install, and the location of the waterproof gasket needs to be more precise to achieve the waterproof effect; in addition, this kind of waterproof gasket has poor reliability and poor waterproof performance. The above-mentioned patents have made improvements in terms of lighting and heat dissipation, but if they are used for a long time in such a harsh environment in the freezer, problems such as waterproofness and light performance will occur.
