评价一个节能灯产品的好坏，九游J9 应该从下面几方面考虑。

Evaluate the stand or fall of an energy-saving lamp products, we should from the following several aspects to consider. 

 

  1.安全性。包括以下几个方面：

1. The security. Including the following aspects: 

 

  a.灯头（铁或铜、铝）与塑件的结合是否紧；

A. lamp holder (iron, copper or aluminum) and the combination of the plastic parts is tight; 

 

  b.灯管与下壳的塑件结合是否牢靠；

B. whether tubes with plastic shell under a firm; 

 

  c.上壳塑件与下壳塑件卡位是否紧固，高温下是否能脱离；

C. on shell plastic parts and the shell plastic parts for fastening, can under the high temperature; 

 

  d.外壳塑件是否采用阻燃耐高温（180℃以上）材料；

D. whether the shell plastic parts with flame retardant high temperature (above 180 ℃) materials; 

 

  e.电子镇流器线路中的骨架、线路板有无采用阻燃材料；

E. skeleton in electronic ballast circuit, circuit board presence of flame retardant materials; 

 

  f.电子线路中有无采用适当的保险元件或保险管。

F. for adopting appropriate insurance in the electronic circuit components or insurance tube. 

 

  当灯头与塑件接合不牢固，很容易出现灯头在灯座内，灯头通过两根引线与节能灯吊在一起。出现这样的情况，第一方面你去取下节能灯的时候很麻烦，第二又很不安全,即使你关掉电源去换的时候，当你的开关没有控制火线而控制零线时，很容易触电。第三方面引起短路，由于灯头跟电源线的摩擦灯头很容易划破电源线。第四方面，当电源线与灯头或线路板焊接不好时整灯很容易掉下来。

When the lamp holder and plastic joint unstable, lamp holder can occur easily within the lamp holder, lamp holder by two fuses with energy-saving lamps hanging. Appear such circumstance, the first on the one hand, when you go to remove the energy-saving lamps very troublesome, and it's not safe in the second, even if you turn off the power to change, when you switch without control of fire control of the zero line, it is easy to get an electric shock. The third aspect cause a short-circuit, due to the lamp holder with the power cord friction lamp holder is easy to cut the power cord. The fourth aspect, when the power cord and lamp holder or circuit board welding when the lamp is easy to fall down. 

 

  当灯管与下壳塑件结合不牢固的时候，灯管很容易吊在节能灯上面，当上下壳塑件结合不紧的时候一个整体的节能灯会分三部分吊在灯座上，这种事故的发生跟上面第一种一样严重。

When the tube and shell model under a combination of weak, bulb is easy to hang on energy-saving lamps, when not tight upper and lower shell plastic parts combined with energy-saving lamps will be three parts of a whole hanging on the lamp holder, such accidents as above the first serious. 

 

  2.寿命

Life of 2. 

 

  节能灯的寿命由两部分组成：

The service life of energy-saving lamp is composed of two parts: 

 

  a.灯管的寿命：灯管的寿命跟它的原材料、制造工艺、制造设备、以及质量控制及保证体系有非常大的关系。其中原材料首先就影响一个产品的寿命，并决定一个产品寿命长短。但是原材料好，如果工艺、设备、技术及管理没有配合好，只要一个环节出问题，这个产品的寿命周期就会很短。

A. tubes of life: the life of the tube and its raw materials, manufacturing process, manufacturing equipment, and quality control and assurance system have the very big relations. The raw materials affect the service life of a product in the first place, and decided a product lifespan. But if good raw materials, process, equipment, technology and management did not cooperate well, as long as a link to a problem, the life cycle of the product will be very short. 

 

  b.电子镇流器的寿命：一个普通型节能灯的电子镇流器大约由30个元器件组成，如果其中一个原器件损坏，那么这个节能灯就不能点亮；如果一个电子镇流器的原器件非常好，但如果参数适配不好，电子镇流器的寿命也不会长；如果上面两项都做得很好，但如果工艺控制不好，质量管理控制不好，上面的功夫即使做得再好也是白费。

B. the service life of electronic ballasts: a common model of energy-saving lamp electronic ballast is composed of 30 components, about if one of the original device is damaged, so the energy-saving lamps can't light up; If the original device of an electronic ballast is very good, but if the parameter adaptation is not good, also won't grow; the service life of electronic ballasts If above two items are doing very well, but if process control is not good, quality management and control is not good, good even if the kung fu is in vain. 

 

  从上面的分析九游J9 可以看出做出一个产品是由很多环节组成，只要其中一个环节出错，这个产品就做不好。

From the above analysis we can see how to make a product is composed of many links, as long as one of the link error, this product can't do it better. 

 

  3.光通量、光衰及光效

3. The luminous flux, droop, and photosynthetic efficiency 

 

  光通量、光衰及光效是反映一个节能灯产品它是否具备节能的效果，是不是能达到国家标准所规定的参数。

Luminous flux, droop, and whether it reflects a energy-saving lamps lighting products have the effect of energy saving, whether can achieve the parameters stipulated in the national standard. 

 

  4.色容差、显色指数以及整批产品的色温的一致性

4. The color tolerance, color rendering index and the consistency of color temperature of batch products 

 

  色容差、显色指数以及整批产品色温的一致性反应节能灯毛管的光参数的一个重要指标。从这些指标九游J9 可以看出厂家三基色荧光粉的纯度，它的工艺水平，它的技术水平。国家标准规定三基色荧光灯6400K色温的节能灯显色指数要大于78，色容差要小于6；2700K色温的节能灯显色指数要大于80，色容差小于6；好的节能灯产品能达到这一水平。比较差的节能灯由于采用的荧光粉差，工艺又不一致，所以它生产出来的节能灯色容差大于15，显色指数小于50，这对于一些营业性照明很难达到要求，特别在一些大量很用节能灯的场合，由于它的显色指数低，色温的一致性又差，看上去简直眼花潦乱。

Color tolerance, color rendering index and the consistency of the whole batch of product color temperature response of the optical parameters of energy-saving lamps capillary is an important indicator. From these indicators we can see the purity of manufacturer tricolor phosphors, its technological level, its technical level. Tricolor fluorescent 6400 k color temperature of national standard of energy-saving light color rendering index more than 78, color tolerance should be less than 6; 2700 k color temperature of energy-saving light color rendering index more than 80, color tolerance is less than 6. Good energy-saving lamps products can reach this level. More bad of the energy-saving lamps due to poor use of phosphor, craft and inconsistent, so it produced energy-saving light color tolerance is more than 15, color rendering index is less than 50, it is difficult to meet the requirements for some commercial lighting, especially in some large amounts of very with energy-saving lamps, because of its low color rendering index, color temperature and the consistency of the poor, looked at flow rate.
