The LED strong light flashlight mainly plays the role of reducing light loss, reducing astigmatism and glare, as well as controlling the light distance, light area and spot effect. The flashlight reflector cup is an important part of the strong light flashlight. How much do you know about its information? Today, the flashlight manufacturer will give you a detailed introduction to the strong light flashlight reflector cup

1、 Material of glare flashlight reflector cup

At present, the reflective cup materials used for outdoor bright flashlights, industrial flashlights or police LED flashlights are nothing more than plastic, aluminum alloy and glass. The three materials are quite different in optical performance, temperature resistance and impact resistance. For different types of LED flashlights, reflective cups of different materials shall be selected according to the use needs. Different reflective cup materials also use different coating processes to achieve the reflective efficiency of the optical cup. In general, the reflective efficiency of common coating processes is as follows: vacuum meson plating>vacuum aluminum plating>anodizing

2、 Comparison of Coating Processes for Strong Light Flashlight Reflecting Cup

①Vacuum plating medium is mainly used for glass reflector cups. This coating process not only has high reflectivity, but also has good heat dissipation function, which helps to extend the life of LED

② Vacuum aluminizing is commonly seen on reflective cups. Reflective rate of vacuum aluminizing is common on automobile lamps or high light LED flashlights.

③ Anodized coating is also used for reflective cup. However, the reflectivity is only half of that of vacuum aluminum plating. The utility model has the advantages of anti ultraviolet and infrared ray damage.

Through the above introduction, it can be found that the aluminum alloy reflector cup with vacuum aluminum coating is more suitable for LED strong light flashlight in terms of heat dissipation, reflective performance and cost.
