LED flashlight is too light, just a little, especially bright
The spotlight effect of orange peel cup is worse than that of smooth cup of the same type, but the light spot effect is obviously better than lightFace cup, more evenly. Features: the size of reflector can be designed freely, but the bigger and deeper the light cup, the better the concentration effect, the worse the light intensity
The reflector cup is focused on light by using a lens designed by an optical path, and can be divided into a smooth cup and an orange peel cup. The light cup has better focusing effect and less scattered light, but the spot effect is poor and uneven
The concentrator LED flashlight is commonly used: 1: lens: through the lens optical design strictly to light gathering characteristics: small size, good convergence effect, but limited in scope, only suitable for large divergence angle and luminous coreSmaller led.
