With the gradual maturity of LED technology, more and more lighting fields are occupied by LED, an energy-saving and environmentally friendly lighting method. From household lighting to municipal engineering lighting to portable lighting equipment, LED lamp beads can be seen everywhere. Among them, LED flashlight is a relatively large industry in LED lighting. At present, LED lamp holders often use LED lamp beads to cooperate with reflectors to achieve light concentration. In order to pursue higher brightness (lumens), many manufacturers often put them in a lamp holder. Set multiple LED lamp beads, and then gather light through an integrated reflector with multiple small reflective bowls, and this type of reflector is often made of aluminum, so it will involve production processes such as pressure casting, multiple small reflectors The integrated reflector of the bowl will have higher requirements on the casting mold. At the same time, due to the small size of the small reflector and the depth of the cup, the actual light gathering ability of a single lamp bead is often lower than that of a single large reflector. Therefore, it will lead to an increase in production costs and a decrease in reflection and light-gathering effects.
