LED lights are not widely used in the flashlight industry. Generally, led flashlights of different brands have different characteristics. In addition to the main luminous body, different light concentrating methods will also bring different brightness and spot pattern effects, so what are the characteristics of different light concentrating methods?.

• Reflective cup focusing: The light is focused by a lens designed in the optical path, which can be divided into a glossy cup and an orange peel cup. Glossy cups have good condensing effect, less scattered light, but poor and uneven light spot effects; The orange peel cup has a worse condensing effect than the same type of smooth cups, and more flooding, but the spot effect is significantly better than that of the smooth cups. More evenly.

  Features: Small size, good convergence effect, but limited application range, only suitable for LEDs with large divergence angle and small optical core.

• Lens condensing light: adopts a strict optical path design lens to condense light

  Features: The size of the reflector can be freely designed, but the larger and deeper the light cup, the better the light-gathering effect and the worse the flooding. At present, most of the strong light flashlights use this design

• The led itself condenses light: generally used for low-power leds

        Features: no need to design the light path, only rely on the optical design of the led itself to condense light, the condensing effect is poor

• Other light-gathering methods: such as optical fiber and other light-gathering methods that are rarely used in flashlights

   There is no absolute standard for different concentrators to judge their advantages and disadvantages. Different groups also like different characteristics. So which is your favorite and the best way to concentrate?
