Many people know that UV power lamp is composed of UV power lamp tube, lamp shade, transformer (ballast), capacitor (trigger), so they may not know much about the lamp shade of UV power lamp. Here we will introduce how to choose the lamp shade of UV power lamp.




Generally speaking, the types of reflector cover are focusing, non-focusing and multi-faceted reflecting, while the usual use is focusing. The structure of the reflector is characterized by concentrated light energy of the reflected UV power supply, high efficiency of light curing, conducive to the curing of ink with thick ink layer, and can completely cure the deep layer of ink. In this respect, attention should be paid to the material selection and shape of the reflector.



Material of reflector:



Pay attention to the selection of materials must choose aluminium, but not iron or stainless steel in order to save costs, because stainless steel plate will become black at high temperature, after blackening not only will not play a reflective role, but also absorb light. The best reflective effect is mirror alumina plate, whose reflectivity can reach more than 80%, thus greatly improving the utilization of ultraviolet radiation. So when choosing, we should pay attention to the material of lampshade.



2) Reflector cover is an important channel for heat dissipation of UV power lamp, so the outer side of aluminum cover should be processed into radiator to increase the heat dissipation area. Reflector cover plays a very important role in UV power curing device. The shape of the shape reflector cover is to ensure that the UV power light can be gathered together, so the shape of the semi-circular arc is the best choice. Also pay attention to the location of the UV power lamp tube to ensure that it is in focus. The main purpose of these details is to reduce the energy waste in the production of UV power lamp.
