Which two kinds of waterproof treatments are usually done for LED linear lights?

2021-08-25


  LED line lights rely on simple lines. Through creative design and free division of space, various fashionable and simple shapes and light and shadow effects are constructed, highlighting the ultimate beauty of linear lighting and promising future market prospects. In the past two years, with the popularity of LED linear lights, more and more lighting manufacturers have participated in it. In recent large and small exhibitions, the linear light exhibition hall has attracted a lot of attention with its individuality. Because of the influx of a large number of manufacturers, there are more and more types of LED linear lights. At present, the line lamp styles of the entire lighting industry are quite rich, with more than 300 styles, but the structure of these line lamps is basically similar, and the only difference is weight, size and surface craftsmanship.

    Generally, there are two methods for waterproofing LED linear lights: the first is to install a transparent waterproof shell, and use the whole shell for protection; the second is to add potting glue for sealing and waterproofing (such as transparent epoxy resin or silica gel, etc.) ).

 At present, many LED linear lights have unreasonable structure design. The light source is installed with potting epoxy resin, and the waterproof is realized by installing glass. The waterproof seal is not complete, and it is difficult to prevent rainwater from penetrating into the light source, resulting in a short circuit. In addition, epoxy resin molding The potting structure of the encapsulation structure produces thermal expansion and contraction due to the influence of temperature, which leads to the destruction of the lamp housing, and the existing lamp housing has a poor heat dissipation effect, which seriously affects the service life of the light source.

    The conventional SMD LED linear lamp is filled with glue on the original lamp beads to achieve waterproof effect. The glue covers the lamp beads, the color temperature of the lamp beads will change, and the color temperature will rise. The color before the glue is better than the color temperature before the glue. If the float is high, and if you use low-priced glue, it will chemically react with the lamp bead colloid, and the lamp bead may die or light decay. The use of good glue will only delay the light decay time of the lamp bead. The linear lamp with lens does not have these drawbacks at all. After the lens is put on the lamp bead, it is equivalent to a protective cover for the lamp bead. The glue filled with glue will not touch the lamp beads, the color temperature of the lamp beads will not change, and the lamp beads have a longer service life. And you can bring glass and brackets, and you can also achieve the effect of high-power LED wall washer, which looks more high-end and high-end.

    LED linear lights can be controlled by a built-in microchip. In small engineering applications, it can be used without a controller. It can achieve dynamic effects such as gradation, jump, color flashing, random flashing, and gradual alternation. It can also be controlled by DMX. Achieve effects such as chasing and scanning. It is more convenient in operation and application, which is one of the reasons why line lights are favored by more and more customers.
