1: lens focus: the use of light through the strict optical path design of the convergence of the light.
\nFeatures: small size, convergence effect is good, but the limited range of use, only for a large divergence angle and light core smaller led.
\n2: reflective cup condenser: the use of light through the design of the lens to focus light.
\nIt can be divided into smooth cup and cup of orange peel, better scattering concentration effect of smooth cup less light, but light effect is poor, uneven; concentrating effect than the same type of cellulite cup cup to smooth, pan light more, but the spot effect was significantly better than that of smooth cup, than the average.
\nFeatures: free to design the size of the reflector cup, but the light cup, the deeper, the better the spotlight effect, the worse the flood.
\n3:led itself in the spotlight: generally used in small power led flashlight<\/a>.
\nFeatures: no need to design light path, relying on the optical design of the LED itself, the spotlight effect is poor.
\n4: the other gathering: for example optical fiber is very small in the torch gathering way.<\/p>\n","protected":false},"excerpt":{"rendered":"
