AI Technical Summary
In existing flashlights, the low beam is turned off when the high beam is on, resulting in poor illumination of the area around the user.
Design a photoelectric module for a flashlight, which uses a lens with a first reflector and a second reflector inside. The high beam LED illuminates the object through the plane of the lens, and the low beam LED illuminates the area around the user through the oblique surface of the lens. The lens is square, and the reflectors are conical and spaced apart to enhance light source reflection and heat dissipation.
It enables effective illumination of the user's surrounding area even when the high beams are on, improving the ease of use of the flashlight.
