There are many types of energy-saving lamps on the market, and the technology is more advanced and more environmentally friendly. The data shows that LED energy-saving lamps save 80% energy compared to incandescent lamps and 50% less energy than fluorescent energy-saving lamps. LED lamps have the advantages of energy saving and environmental protection, and the development of the lighting industry has become a major trend. The obvious advantages of LED energy-saving lamps can be reflected in the following aspects:
1. Low-voltage power supply and low power consumption: Generally speaking, the working voltage of LED energy-saving lamp is 2 to 3.6V, and the working current is 0.02 to 0.03A. That is to say: it consumes no more than 0.1W;
2, small size: LED energy-saving lamps are basically a small chip is encapsulated in epoxy resin;
3, long service life: under the right current and voltage, its service life can reach 100,000 hours, almost no maintenance. In addition, the LED energy-saving lamp has a complete epoxy resin package, which is stronger than the bulb and the fluorescent tube, and there is no loose part in the lamp body, which is not easy to be damaged;
4, high brightness, low heat: incandescent lamps and tungsten halogen lamps for general lighting, although cheap, but low luminous efficiency, due to the thermal effect of the lamp and white power consumption; LED lamps as lighting lamps, not only high efficiency, and cold The light source generates almost no heat consumption;
5. Environmental protection: LED lamps are made of non-toxic materials, unlike mercury-containing fluorescent lamps, which can cause pollution and can be recycled and reused;
6, LED energy-saving lamps also have the characteristics of no flicker, strong applicability, high stability, short response time;
Since the technology and product attributes used in LEDs are quite different from those of conventional lamps, the current general lighting safety standard specifications are clearly not applicable.
Yibo Technology Certification Center (EBO) specially wrote this article to explain the current safety requirements of LED lamps (taking UL standards as an example).
(1) Safety specifications for LED lamps:
With the improvement of technology, the use of LED lamps has been applied to the backlights, interior lighting, brake lights, LCD TVs, laptop backlights, etc. In the past two years, it has become the main lighting system. The scope of application can cover, outdoor, commercial, and home. The products are:
Category (lighting) products
Building garden lights, searchlights, ladder lights, balcony lights, etc.
Outdoor street lights, column lights, etc.
Commercial advertising lighting, display cabinet lighting, etc.
Home ceiling lamps, wall lamps, kitchen cabinet lights, vertical lights, table lamps, etc.
LED light source manufacturing technology is enhanced, application level is widened, and consumer safety is guaranteed. UL has developed UL8750, a safety standard for LED modules and lighting fixtures, to regulate LED lighting products, and was officially released in 2009. This standard is an essential safety regulation for the sale of LED products to North America. It is applicable to all kinds of products with LED as the main light source, including lamps, bulbs, drivers, etc. In addition to safety regulations, LED light source lighting products must be installed in the future. Verification of the special properties of the LED light source and module.
(2) Classification of LED lamps in UL standards:
For the three basic product categories, such as LED lamps, LED bulbs and LED power supplies, when the corresponding products are extended to the finished products or parts, the safety standards and related precautions are different, as follows:
1, LED lamps:
Application product safety standards precautions
Indicator light UL48
Hand-held lights, kitchen cabinet lights, table lights, standing lights, wall lights, etc. (all with power cord plugs) UL153 covers portable luminaires, connected via a plug of the power cord to a branch circuit nominally 120V, 15 or 20A
Christmas light string UL588
Emergency indicator, exit light UL924
Display cabinet, mirror light UL962
Stage light UL1573
Step lights, recessed lights, ceiling lamps, chandeliers, wall lamps, street lamps, column lights, etc. (without power cord plugs) UL1598 covers fixed luminaires, used in non-hazardous areas and installed on branch circuits below 600V.
Night light UL1786
Low-voltage garden light (without power cord plug) UL1838
Water pipe light UL2388
2, LED bulb:
Application product safety standards precautions
Indicator bulb UL496
LED bulb (ANSIBase), including the driver circuit UL1993E27Base is a European standard and cannot be used in the North American market. North American market requires E26Base
LED bulb (non-ANSIBase) with driver circuit UL496
LED module, without drive circuit UL8750
3. LED driver and power supply:
Application product safety standards precautions
Power supply (with LPS safety circuit) UL60950-1 output LPS safety circuit, LED module and LED control module do not need electrical enclosure (Enclosure)
Power supply (without Class 2 safety circuit) UL1012 LED module and LED control module need to provide appropriate electrical enclosure (Enclosure) protection
Power supply (with Class2 safety circuit) UL1310 output Class2 safety circuit, LED module and LED control module do not need electrical enclosure (Enclosure)
Driver (with LPS/Class2 safety circuit) UL935 output LPS/Class2 safety circuit, LED module and LED control module do not need electrical enclosure (Enclosure)
Low voltage garden light power supply UL1838 LED module and LED control module need to provide appropriate electrical enclosure (Enclosure) protection

Digital currency transactions allow users to convert existing digital currencies into other digital currencies. The entire transaction does not involve any legal tender. Because of the relatively loose regulation, the mainstream digital currency trading platform also opened this function.Digital Asset Exchange (DAE) is a platform for matching transactions between digital currencies, digital currencies and legal currencies. It is the main place for encrypting the circulation and price determination of digital currency transactions.
Compared with traditional stock exchanges, digital asset trading platform not only matches transactions, but also plays the role of market maker and investment bank. The role of the market maker in the trading platform can increase the liquidity of the market, and the trading platform can earn the transaction price difference. The role of the investment bank of the trading platform is to provide services such as issuance and underwriting of digital currency, from which the trading platform collects money fees, or collects deposits in the form of community voting of the trading platform.
