The various types of energy-saving lamps on the market, and technology more advanced and more environmental protection of LED bulbs. Data show that the LED energy-saving lamps save energy than incandescent bulbs 80%, than fluorescent bulbs save electricity 50%. LED lamps and lanterns has the advantage of energy saving, environmental protection, in the development of the industry of lamps and lanterns has become a main trend. LED energy-saving lamps and lanterns, obvious advantage can be reflected from the following aspects
1, low voltage power supply, low power consumption in general, the working voltage of LED bulbs is 2 to 3. 6 v, working current is zero. 02 to 0. 03A. This means that it consumes less than 0. 1 w;
2, small LED bulbs is basically a small chip is encapsulated in epoxy resin;
3, long service life under the appropriate current and voltage, the service life of up to 100000 hours, almost no maintenance. In addition, the LED energy-saving lamps with full of epoxy resin encapsulation, it is strong than light bulbs and fluorescent tube, no loose parts in the body, not easy to damage;
4, high brightness, low quantity of heat of general lighting incandescent and halogen tungsten lamp is cheap, but the low light efficiency, due to the heating effect of the lamp and the power consumption in vain; LED lamps and lanterns as lighting the lamp, not only the high light efficiency, and cold light source is almost do not produce hot electricity;
5, environmental protection, LED lamps and lanterns is made from non-toxic materials, unlike fluorescent mercury can cause pollution, can be recycled;
6, LED energy-saving lamps have flicker-free, strong applicability, high stability, short response time, etc;
because LED the use of technology and product properties are very different from traditional lamps and lanterns, so the current general lamps and lanterns has clearly not applicable safety standards.
million certification center of science and technology ( 公祭活动) , I write this article to explain the current LED lamps and lanterns of security testing requirements ( UL standard, for example) 。
( A) Safety standards of LED lamps and lanterns of
as the improvement of technology, the use of LED lamps and lanterns is not the simple application in the past several decades, lights, lights, etc. , gradually used in the mobile phone back light, car lighting, brake light, LCD TV, laptops back light and other auxiliary lighting; And within two years, its start into a main lighting system, the application of the category covers, outdoor, commercial, and home, etc. , products, respectively is
category ( Lighting) Products
building garden lights, searchlights, stair lights, balcony lights
outdoor lights, such as column lamp, etc.
commercial lighting, display lighting, etc.
home to absorb dome light, wall lamp, hutch ark lamp, floor lamp, desk lamp, etc.
the LED light source manufacturing technology promotion, wide application layer surface change, is committed to safeguard consumer safety UL has established for UL8750 LED module and lighting lamps and lanterns, safety standards, to regulate the LED lighting products, and in 2009 formally. This standard is the industry sales LED products to North America essential safety norms, apply to the LED as the main source of various products, including lamps, bulbs, drives, etc. , in addition to the future of LED lighting products have safety norms, more should be concerning the special properties of LED light source and the module for validation.
( 2) LED lamps and lanterns in the classification of the UL standard
for LED lamps, LED bulbs and LED power supply and so on three basic product classification, the corresponding extended to finished products or components, its corresponding application products of different safety standards and relevant points for attention are not the same, and elaborate on the following 1, LED lamps and lanterns is
application product safety standard precautions
light UL48
hand ark of hutch of the lamp, lamp, table lamp, floor lamp, wall lamp, etc. ( To take the power cord plug) UL153 cover portable lamps and lanterns, through the power cord plug connection nominal is 120 v, 15 or 20 a branch circuit
Christmas lights string UL588
emergency lights, exit light UL924
display cabinet, mirror lights UL962
stage light UL1573
step lamp, downlight, absorb dome light lamp, droplight, wall lamp, street lamp, column, etc. ( Don't take the power cord plug) UL1598 cover fixed type lamps and lanterns, used in the danger zone and installed in less than 600 v branch circuit.
small night light UL1786
low voltage garden lamp ( Don't take the power cord plug) UL1838
the pipe lamp UL2388
2, LED bulbs,
application product safety standard precautions
indicator bulb UL496 LED light bulb (
ANSIBase) Driving circuit, containing UL1993E27Base is European rules, cannot use in the north American market. The north American market need E26Base
LED bulbs, Not ANSIBase) , including driving circuit UL496 net
the LED module, do not contain driver circuit UL8750
3, LED driver and power supply
application product safety standard precautions
power supply ( Can with LPS safety loop) UL60950 - 1 output LPS safety circuit, the LED module and LED control module without electrical shell ( 外壳)
