Abstract:
An LED flashlight lamp for a mobile device, comprising a circuit board (1), an LED lamp bead (2) fixed onto the circuit board (1), and a light-transmitting cup (3) fixed onto the circuit board (1) and disposed above the LED lamp bead (2). The light-transmitting cup (3) comprises a physical circular truncated cone-shaped convex lens (31) and a lampshade (32) integrally formed with the convex lens (31) and circumferentially disposed outside the convex lens (31). The center of the bottom end of the convex lens (31) is arranged with a light passing hole (33), and the light passing hole (33) is located right above the LED lamp bead (2). The inner surface of the lampshade (32) is a frosted surface. Light emitted from the LED lamp bead (2) is gathered and then transmitted by using the convex lens (31); the gathered light is concentrated and thus can achieve illumination to a far distance, thereby yielding the effect of a conventional flashlight; moreover, the structure is compact and convenient to mount on a mobile device.
