Since January 1, 2014, the United States government announced a full "the white", after the north American market at present is becoming a new hot industry growth, the demand for LED lighting is strong fermentation. According to the latest market report, North America accounted for the proportion of the global LED lighting market is about 25%, in terms of commercial lighting, North America, according to the existing market such as Troffer, T tube type lamps and lanterns for the mainstream. Different from the domestic market, the north American market is more mature and rational, relevant policies and regulations are relatively perfect, taller also to the detection requirements for products.
he north American market for LED lights of The main performance criteria are: Energy Star Energy Star, DLC (The DesignLights Consortium), LED Lighting Facts, The following table, their different testing standards and application scope:
DLC: DLC certification product catalog is used to in the United States has not yet been "ENERGY STAR (ENERGY STAR)" standard covers the promotion of high performance LED lamps and lanterns, its scope and ENERGY STAR product range is not overlap, namely, if the ENERGY STAR products into its system, DLC permanent transfer out the product.
Energy Star: Energy Star test products first to pass the safety test, provide IES - LM - 79-08 test report and according to the LM - 80-08, TM - 21-11 get the life of the report, the test of time and Energy consumption is fixed, Energy Star market supervision is very strict, every year to all get the EPA Energy Star product will be randomly selected from the market products to spot check regularly, selective examination unqualified products will immediately cancel the Energy Star qualification and shall have the right to let the manufacturer to consumers for further compensation.
According to statistics, the commercial lighting market report in terms of commercial lighting, North America, according to the existing market such as Troffer, T tube type lamps and lanterns for the mainstream. In the table below is released on October 2, 2013 DLC v2.1: technical requirements form the LED Troffer replacement lamp specifications:
DLC different requirements for different size linear lamps and lanterns, and joined the stricter optic spatial distribution requirements. DLC for two inches linear minimum optic lamps and lanterns is 800 lm (half of the lamps and lanterns is 4 inches), the lowest photosynthetic efficiency is 100 lm/W, and for its 3 - lamps Troffer, require minimum luminous flux is 2000 lm, lowest photosynthetic efficiency is 85 lm/W. DLC v2.1 not of u-shaped tubes do one step closer to the specification, therefore standard does not apply to U tube.
In September 2014 began to implement the latest version of specification V1.0 "energy star" lighting lamps and lanterns, allowing new product model automatically through the authentication, as long as these models will not violate any of the changes in the performance standards or any other requirements of this specification. In addition, this specification update the part "tolerance" to make specific tolerance is consistent with the safety reporting requirements of UL1993, used to measure temperature change test data has been extended. Has been clear about the luminous efficiency and light output values of tolerance range. Specific product variant parts removed the reference information of the new model. For those who do not need to accept the first certification and tolerance within the allowed scope, new model must receive at least 3000 hours of testing available energy star certificate.
For claiming the lamps and lanterns, the service life of 25000 hours or less after 3000 hours test if can achieve specific optic retention, can obtain the energy star certification. But through the complete (temporary) certification, the service life of lamps and lanterns for continuous 6000 hours of testing. Argues that the service life of up to 30000-50000 hours of lamps and lanterns, obtain temporary certification, can test time required for a complete certification and so on. Claims, for example, the service life for 30000/50000 of the service life of lamps and lanterns to complete certification, respectively after 7500 hours and 12500 hours of testing.
Familiar with north American standards is the key to enter the north American market, not only can be used for reference for domestic specification market also. Previously, for example, there are media reports the guangzhou city industrial and commercial bureau sampling was carried out on the LED ball steep light 50% of the products unqualified news, some enterprises only to recall defective products, some enterprises package, disorderly think the ministry of commerce and industry only check safety performance, it is difficult to standardize the market. Only to publish relevant standards as soon as possible, strengthen the core LED lamps and lanterns of the security and performance test, can we truly standardize the market.
