Several basic performance for LED

Here introduce several basic performance for LED,those signage companies can take it as a reference when designing .

1、Brightness

Different price for different brightness.LED should be conformed with laser I standard if applied in LED lighting.

2、Anti-static ability

LED with strong anti-static LED ability ,have a long lifespan,so the price is a little higher.Usually LED only which anti-static is above 700v can be used in LED lighting.

3、Wave length

Constant wave length LED,constant color,if color consistency required,the price will be higher .It’s difficult for those manufacturers who has not LED testing instrument to produce pure color products.

4、Leakage current

LED single directional conductive lighting object,if reverse current,we called leakage electricity,high leakaged LED,the lifespan will be much shorter,also the price will be low.

5、Emitting angle

Different usage LED has different emitting angle.Higher price for special emitting angle and all diffuse angle

6、Lifespan

Lifespan is the key difference between LED products,lifespan is decided by light decay.

7、Chip

Chip is the emitting object,there is a huge difference between different chip.Japan and America chips usually at a higher price.Chips from Taiwan and China mainland at a lower price.

8、Chip size

Usually the chip size denotes with side length,big size chip has a better quality than smaller ones,the pcolloidrice is in direct proportion to chip size.

9、Colloid

Normal LED colloid usually be called epoxy resin ,LED with uvioresistant and fire  retardant has a higher price,higher quality outdoor LED lighting should contain uvioresistant and fireproof material (Our module use ABS+PC material )

•Every product has different designs,different designs will be applied in different fields,reliability design for LED lights includes: electric safety、waterproof and fireproof safety  

Every product has different designs,different designs applied for different fields,LED lighting reliability design include : electric safety、waterproof and fireproof safety、environment adoption safety、mechanic safety、health safety、safety working time and so on factors.

From the electric safety,should be conformed to relevant international and national standard.since LED is new products,china national standard is a little lag behind,but government provide qualified tests for products,those LED lighting will be at a high price if they have international safety certification ( like GS、CE、UL etc ) and national product quality certification,because those products was more reliable in safety design.consumers needs to identify the authenticity of the certification .There are not many factories has both international and national product certification.

From the health aspects,Product will be at a high price if use nontoxic material,especially for indoor LED lighting,don’t use LED lights with peculiar smell.Only several LED manufacturers use nontoxic material for production,,for the distinguish method,u can use nose,product with toxic will be much cheaper than those with nontoxic ones.like plumbum、mercury、cadmium and so on toxin needs to be analyzed by specialists.

From environment safety ,product price will be at a higher price if has reliable dustproof、moistureproof、waterproof、ultraviolet-proof、low temperature cracking-proof.

From safety working time,normal customers cannot distinguish the ok product and defects,designing reliability、components good or not,that matters price.project used lamps,do not use low price、shoddy products.Price will be vastly different in case of using different cables .some manufacturers use electronic components from old machines,recycle plastics,recycle metal material to produce LED lamps,price of those defects will be lower than normal LED lamps for 50%
