UL认证（UnderwritersLaboratoriesInc.）美国是一家公司在产品安全认证和安全从事组织制定的标准，甚至在北美拥有世界各地产生重大影响。在美国的总部设在产品评估和标准从事编写的110年历史，每年测试已超过18,000种产品，关于UL标志超过19亿多产品的使用在世界各地，有更多的超过60家。 UL认证，根据商务部，公司规划照明总经理EliPuszkar部透露：UL认证，在发展的LED系列（产品）的安全评估标准的过程。
在在技术创新领域的照明
，LED应用无疑是最令人兴奋的，它将改变整个照明市场的结构，其广泛应用指日可待的。的LED时，技术本身并不是一个新事物，在很多年前，已开始利用LED照明设备和仪器的使用。随着技术的进步，芯片和新材料的性能改进方面，都有新的提高，LED的亮度和寿命大大提高，从而促进在该领域的LED更广泛。

今天，许多厂家都推出了自己的LED照明产品，LED照明与大在不远的将来大规模使用，我们将看到LED照明应用将成为主流产品。寿命长，几乎没有这两个特点维修深深吸引了大量的灯光设计师，其功耗低，适应性强，色彩和良好的可控性的优势，加上亮度，使LED灯照明产品将成为新的宠儿。

以确保新的LED照明产品能够像一个普通的一样，为使公众接受和信任的照明，UL已开始对LED的安全评估标准的筹备工作。

当一个新产品开发和设计时间，制造商应考虑以下因素影响安全：防止触电，以防止触电

普遍接受xx的两种情况：1分开。电源LED电源产品; 2。直接连接到网格或使用非电源供电的LED照明电源。对于供电的LED产品的使用，作为其自己的电源结果电压和电流的限制，所以不存在触电的危险;为其他电源产品使用的必要的绝缘性能和带电体可触及进行评估，并按照标准。然而，电源设备的使用，同时考虑到在一个特殊的场合使用-和潮湿的环境，如果产品在潮湿的环境中使用，其开路电压不能超过15V的交流（30伏直流电）。避免火灾
为避免
火，有必要使产品测试和评估，如LED间距，散热片结构和材料的使用，壳型和安装位置和工作方法等许多方面。虽然在产品的设计，虽然有一个电源设备的使用，限制能源产品，以避免或减少火灾，但根据UL以往的经验，这些产品仍可能达到90℃以上的高温（美国内美国国家建筑规范要求，安装在地面设备不能超过90℃，一般温度易燃材料）。因此，在LED照明产品的设计，应当考虑在这一领域，并要求在元件表面温度测试温度，灯应在自己的额定工作温度范围。

The United States will soon introduce new standards for LED lamps

UL (UnderwritersLaboratoriesInc.) the United States are a company engaged in product safety certification and safety standards established by organizations, and even in North America has a significant impact all over the world. Headquartered in the United States engaged in product evaluation and criteria for the preparation of 110-year history, the annual test has more than 18,000 kinds of products, the use of the product on the UL mark more than 19 billion, around the world have more than 60 subsidiaries . UL, according to Ministry of Commerce, general manager of corporate planning lighting EliPuszkar revealed: UL is in the process of developing a series of LED (Product) security evaluation standard.

in the lighting in the field of technological innovation, LED applications are no doubt the most exciting, and it will change the entire lighting market structure, and its wider application is just around the corner. Speaking of LED, the technology itself is not a new thing, in many years ago, had begun to make use of LED light apparatus and equipment. As technology advances, chips and materials both in terms of performance improvement and enhance the new, the LED’s brightness and Life expectancy has greatly improved, thereby promoting the LED in the field more widely.

Today, many manufacturers have launched their own LED lighting products, LED lighting products with a large-scale use of the near future we will see the LED lighting applications will be mainstream. Long life and virtually no maintenance of these two characteristics are deeply attracted a large number of lighting designers, coupled with its low power consumption, adaptability, color and brightness of the advantages of good controllability, so that LED lamp Lighting Products will become the new darling.

in order to ensure that the new LED lighting products like an ordinary can, like lighting for the public acceptance and trust, UL has begun the preparation of LED security evaluation standard.

When a new product development and design time, manufacturers should consider the following factors that affect safety: to prevent electric shock in order to prevent electric shock

generally treated separately for two situations: 1. Power supply LED power supply products; 2. is directly connected to the grid or the use of non-power power supply power supply of LED lighting. For the use of power supply’s LED products, as a result of its own power supply has voltage and current limits, so there is no risk of electric shock; for the use of other power supply products are necessary for its insulating properties and charged body can be touched to carry out assessments, and in accordance with the standards. However, the use of power supply devices, taking into account the use of a special occasion - and humid environment, if the product is used in humid environment, its open circuit voltage should not exceed 15V AC (30 V DC). Avoid fire

for the avoidance of fire, it is necessary to make many aspects of product testing and assessment, such as LED spacing, heat sink structure and the use of materials, shell type and installation location and working methods and so on. Although in the design of products despite the use of a power supply device to limit the product of energy so as to avoid or reduce the fire, but according to UL past experience, these products may still reach above 90 ℃ high temperature (inside the United States National Building Code requirement to install flammable materials in the general temperature of the surface equipment can not exceed 90 ℃). Therefore, in the design of LED lighting products, should be taken into account in this area, and required test temperature, lamp in the surface temperature of the components should be rated in their own temperature range.
