As the fourth -generation light source , LED lighting is known as the high luminous efficiency , energy saving , long life, maintenance-free , highly safety and reliability , and environmental protection and so on . With the rise of LED lighting products and the popularity ,its product quality is paid more and more attention by the public.
The pass rate of security is 80-90%
According to the preliminary statistics , the safety pass rate of the product checked from the manufacturers is about 80% ; the one-time pass rate of safety and performance of the product the enterprises entrust check is 70%.
According to the briefing , because LED lighting products too rapidly develops , the quality status and trends is not optimistic. the LED light that is used for Indoor Lighting is the Downlight, LED tube light, LED light bar , LED ceiling light and other forms ,according to the analysis of the testing situation of the LED lighting product, the failed projects mainly focus on thefour aspects: First, unequal power , the labeled power of the LED lights is incompatible with the standard limits power , which generally tend to be large , easy consumption ; Second:the luminous flux reach the value the manufacturer claim,which is generally low ; third is that the rate of the maintain is not enough, because of chip quality and other issues, the rate of the maintain light is not high, which is easy to darken ; Fourth us structure , the protection against electric shock and fire and heat-resistant of insulating material is failed to make the original protection against electric shock of the lamp is failure, resulting in that the live parts is exposed or the short circuit and other safety hazards .
China is still reference to the testing standards of the U.S. “Energy Star ” to test the safety performance and life of the LED lighting product , other supporting standards and supervision and management measures have not yet be perfected, the national testing agencies are being made preliminary data collection, actively participate in the establishment of national standards of the ” reliability test methods of the Semiconductor LED lighting ” .
Which LED lights is suitable for indoor lighting ?
The Prettier and brighter,not the better , we should be more concerned about security. Should choose the lamps which is of high protection level , structural, and low color temperature . A lamp includes two parts that is the lamps and lighting, of which the fixture ensure the safety of use , such as the starting power of the LED lamp is very important to ensure the integrity of its sporadic ; the sources have good light color , and its luminous flux and color temperature should meet the standard requirements , such as the lamp used for writing should have a low color temperature light , high color rendering index , but also restore the original shades ; pay attention to the stroboscopic of the high frequent lights , because the security is controlled by the national compulsory standards , and the power , lumen light and other optical characteristics are determined by the manufacturer ; what should be considered is more blue light hazard the LED light emit.
How to detect ?
The safety, light, life is called ” three threshold .” of the LED lighting products
There are are three basic indicators testing the safety of the LED lighting product: First, dielectric strength, namely anti- pressure capability ; Second, the insulation resistance and leakage current ; Third,the grounding resistance .
The light detection is firstly accomplished by the integrating sphere to measure the performance and characteristics of the light and color , the large distributed photometer lamp is used to measure the light distribution to identify whether there is the light pollution on the surrounding environment . Followed by 3000 hours or 6000 hours ignition cycles testing the light color ,those meeting the requirements is qualify.
Inspection approach
Having bought the LED lighting products, we want to check it is eligibility or not , the semiconductor lighting products can be sent to the National Quality Inspection Center to commission the inspection , the inspection cycle of the routine project is 10 days, the number of samples tested depend on the test need, the inspection charging is determined by the fees of the state regulation standards .
Nowadays,the LED flood light such as the portable 10W LED flood light and LED tube light are the most widely used as the representatives of the decorative lighting and the home lighting in daily life,the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood light is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness is needed to illuminate,meanwhile,there a large number of factory engaging in developing and producing the LED light,Lead Lighting is just one of them,which adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED floodlight so that fully guaranteed stable and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while low voltage constant current driver ensure the AC can be converted into the DC to improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is Known as energy-saving and environmental protection ,login http://www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.
