The LED spot light at the present stage, mainly to replace traditional halogen tungsten lamp, safety related requirements mostly refer to the traditional lighting requirements, and according to the characteristics of LED lamp, has formed a set of standard. Currently, the certification of LED cob spotlight, mainly European CE and North America UL in the international.
In CE certification contains both LVD and EMC, LVD which is executed (the upgrade IEC 62560) in accordance with the EN60968 standard; EMC in accordance with EN55015, EN61547, EN61000-3-2 and EN61000-3-3 standards. In addition, LED lights typically require additional reference to IEC 62471, light biosafety testing. In North America, usually require UL safety and FCC electromagnetic compatibility certification. The implementation of UL standards for UL1993, UL8750 and UL1310; the execution of the FCC standard is FCC PART15 Subpart B.
In addition, the performance of LED spotlight bulb, there are many standards. US Energy Star (ENERGY STAR) related requirements; China has energy certification requirements, performance standards for CQC 3129-2010. These requirements are for the LED spot light color temperature, color rendering index, initial luminous flux, luminous efficiency, lumen maintenance, life, the center light intensity, the nominal power, power factor, product identification, etc. provisions.

What are the strengths of LED tube lamp
LED Tube with high luminous efficiency. Traditional fluorescent lamp for 60-70LM/W, LED tube lamp light efficiency is 100LM/W. In addition, the fluorescent lamp is 360 degree light, the effect of light is only about 70%, LED Tube is 120 degree light, luminous surface is centralized, the actual light effect many enhancements than the fluorescent lamp. Brightness of the 18W LED Tube can be equivalent to the traditional 40W fluorescent lamp and LED tube light is softer.
LED Tube life is long, can reach 30000-50000 hours, for 10 times of the ordinary fluorescent lamp, because LED light tube don't need ballast, starter and other accessories, do not need regular replacement of lamp.
LED Tube installation is relatively simple. Its power supply can be a built-in or external. The built-in power LED Tube when installed, remove the old lamp and put on a LED tube, and remove the ballast and starter, can be directly connected with the commercial power. External power supply LED Tube for general with a special light bracket, the replacement of the original can be used for fluorescent lamp.

What are the advantages of LED ceiling down light
LED as the light source for lamps has a few decades, but has gained great development. At present, many kinds of LED lamps, mainly including LED ceiling down light, LED spot light, LED bulb and so on. One of the most promising development is LED down light.
LED down light adaptability is good. LED downlight no startup delay, the circular telegram can immediately the normal work, no need to wait for a long time, the light source color is good, close to natural light, quick installation and flexible, any angle is adjustable, strong versatility, wide range of application.
LED down light convenient repair. LED light source can be composed of multiple sets of LED module, LED lamp can be composed of many LED cavity modules, no mutual interference, convenient maintenance, power supply and light independent design, damage just to replace the bad part.
LED down light good starting performance, fast and reliable, only a millisecond response time, can achieve full lumen output, LED downlight shock resistance, weather resistance good, long life.
LED down light CRI is higher. The CRI of the LED light source is higher than the traditional light source, at the current level, the CRI of LED down light can reach 70 to 85.
LED downlight has very obvious advantages in performance and price, more favored by consumers. Now, LED downlights are mainly used in office lighting, home lighting, shopping malls lighting and factory lighting and other places, the development of space is very broad.

The advantages and application of LED flat panel lighting
The LED flat panel lighting design is unique, the light through the light guide plate with high light transmittance of the formation of a uniform plane light effect, illumination uniformity is good, the light is soft, comfortable and bright, can effectively relieve eye fatigue. LED panel light is a high-grade indoor lighting, the outer frame is made of aluminum alloy by anodic oxidation, the light source is LED, the entire lighting design, beautiful and simple, luxurious atmosphere, not only has good lighting effect, but also gives people the feeling is very good.
LED lamp has so many advantages. Now a lot of the hotel and conference rooms to choose LED panel light, there are also many families choose LED panel lighting. From the appearance point of view, like a flat panel. But its color rendering property index is higher than the traditional tube, the LED lamp luminous efficiency is higher. Although the panel lamp shape is very common, but this simple design with the surrounding metal frame, the LED panel light is very simple and the atmosphere.
LED panel light can be used for energy saving and high color rendering index lighting places, such as hotels, conference rooms, offices and factories, commercial, residential or public facilities, schools, hospitals etc.. The LED flat panel lighting subversion of the luminescence characteristics of traditional light sources, with its thin, surface emitting, energy saving, environmental protection, health and other characteristics of brilliant appearance, is the preferred products of office, family, advertising lamp.

The classification of LED track light
LED track light is a kind of lamp is widely used for business place, usually as spotlights, also have aliases such as: track spotlight, in fact it is a kind of spotlight. Track lamp light irradiation on objects, so that the illuminated objects to obtain good lighting effects, so as to attract people's attention. Here, we briefly to introduce the classification of LED track light.
First, a set of track lamp is the following components:
1, rail head; 2, lamp bracket or shell; 3, drive power and its bracket or shell; 4, the LED lamp beads; 5; a lens or reflector cup; 6, screw and wire.
Track lights mounted on the fixed track bar, lamps and lanterns with at least two fulcrum, usually horizontal fulcrum and the vertical fulcrum, these pivot track lights can flexibly adjust the lamp irradiation direction, i.e. universal regulation.
1, integrated style LED track light:
Why is it called the integrated track lights? Because of the structure can not be separated, a complete lamp by the led lamp manufacturers using industrial fixture assembled, the entire track lights is a set of components, which can not be hand apart.
2, detachable LED track light:
Detachable track lights, that is, the whole lamp is composed of one or more light sources with a rail bracket assembly, the free assembly, and users can conveniently disassembly and maintenance.

How to buy LED spotlight bulb
According to the classification of voltage, LED spotlight bulb can be divided into low voltage LED spotlight and high voltage LED spotlight. Normal users should choose low LED lamp, the LED lamp life is long, and the light effect is relatively good.
LED spotlight light effect have relations with the power factor, if the power factor is bigger, so the light efficiency of LED spotlight will be better. Power factor of LED lamp are generally about 0.5 on the market, the price is cheaper, For most users, the cost performance ratio is good. Some LED spotlight light effect is good, its power factor can reach 0.9, but the LED spotlight price is high, not suitable for ordinary users.
When using LED spot lighting, give off heat, so the user should select quality LED spotlight when buying LED spotlight. And should choose the LED spot light of high quality lamp bead, because replacement LED lamp bead is a very troublesome thing. Today, the uneven quality of LED spotlights, we should learn to distinguish the quality of LED spotlight, and learn to choose high quality LED lighting.

How much is LED tube luminous decay
LED tube luminous decay in less than 10% is qualified in 1000 hours. After used for 40000 hours brightness to achieve 70% were quite outstanding. In fact, the LED tube light fades has already produced at 1000 hours times, but the high power LED light attenuation will be smaller, small power will be larger, of course this is just from the LED itself.
The biggest factor of LED light tube attenuation is LED temperature, if the heat is not good, the temperature is too high, the light attenuation rate will be very fast. Usually said LED decay is in the ideal state, if it is a LED tube, because there are a lot of LED light source, need to consider heat, spacing between LED, the electric current size and lamp shell problems etc..
