By means of the light bar, the colour temperature drift of the one-side-protected LED light bar can be substantially reduced, so that a colour temperature value of a product is very close to a colour temperature value of an LED itself, without converting the colour temperature value of the formed product. The light bar can be used for replacing existing one-side-coated LED strips, and has a very high economic value.
Description
本实用新型涉及照明领域，特别涉及一种单面防护LED灯条。The utility model relates to the field of illumination, in particular to a single-sided protection LED light bar.
目前，市场上的单面覆胶LED软灯带都采用液态胶水通过灌封(或涂覆)在裸板LED软灯条正面产生一层保护层，从而达到一定的防护作用。因液态胶水的加工艺复杂，需要固化时间，生产难度很大；另一方面，由于所有的胶水灌封(或涂覆)的单面防护单面防护LED灯条固化后的胶体都是与LED发光体紧密接触，由于光线的折射使得LED软灯条发出光线的色温发生较大的改变，俗称为色温漂移。因此，单面覆胶的LED软灯条存在生产难度大和色温漂移大的严重缺点，亟待解决。At present, the single-sided laminated LED flexible strips on the market use liquid glue to form a protective layer on the front side of the bare LED strips by potting (or coating), thereby achieving a certain protective effect. Due to the complicated process of adding liquid glue, curing time is required, and the production is very difficult; on the other hand, all the glues are encapsulated (or coated), and the one-side protection single-sided protection LED strips are cured with the LEDs. The illuminant is in close contact, and the color temperature of the LED flexible strip emits a large change due to the refraction of light, which is commonly known as color temperature drift. Therefore, the single-sided rubberized LED flexible strip has serious shortcomings in production difficulty and large color temperature drift, which needs to be solved.
