(1)5mmled
The firstLED is 5MM led ,like the picture,However, this type LED lightLM is too small,After several years ofdevelopment,has failed to meetthe needs of people,Therefore,researcherslooking for betterLED technology.
(2)SMD. Scientistshave been seekinghigher LEDproducts and technologies.So now we have the 3528 SMD ,5050 SMD,5050 SMD have 3 pcs chips,so can make Red ,Green and Blue color to in one SMD.3pcs chips smd Advantage ofbetterbrightness, longerlife time.Depending on thesize, we put themintodifferent SMD types,so we call different SMD name,such as 3528 SMD,3014 SMD,5050 SMD.
(3) High power led In order to meetthe specificlightingneeds ofa number of occasions,ScientistsdevelopedbetterthanSMDLED,ThisLED isa singlepower of1W or more than 1W,so we call them high power led .
