Abstract

The utility model relates to a side luminous touch key backlight structure, which comprises a panel, a reflective ring, a circuit board, a touch key and an LED (Light Emitting Diode) lamp group. The panel is provided with a plurality of touch control areas, the touch control areas are provided with light-transmitting areas, the light-reflecting rings are arranged on the back surface of the panel, the plurality of light-reflecting rings are arranged, and the light-reflecting rings are in one-to-one correspondence with the touch control areas; the circuit board is detachably arranged on the back face of the panel, the touch keys are arranged on the circuit board and electrically connected with the circuit board, the touch keys correspond to the touch control areas in a one-to-one mode, the LED lamp sets are electrically connected with the circuit board and correspond to the touch control areas in a one-to-one mode, each LED lamp set comprises a plurality of LED lamp beads, and the LED lamp beads are electrically connected with the circuit board and correspond to the touch control areas in a one-to-one mode. The LED lamp beads are arranged on the peripheral side of the touch key in a surrounding mode and embedded in the inner side of the reflective ring. Light rays can be uniformly reflected and displayed on the front face of the panel, and the uniform backlight effect of the panel is achieved.

Description

technical field [0001] The invention relates to the technical field of lamp accessories, in particular to a backlight structure of a side-emitting touch key. Background technique [0002] Since the invention of the capacitive screen, touch buttons have been widely used in all walks of life. Traditional mechanical buttons have gradually faded out of the home appliance industry, including the desk lamp industry. The switching lights and debugging of products have basically been replaced by touch buttons. The button also has a backlight effect. The principle is to integrate LED lamp beads of different colors on the touch button. The different colors of the touch button represent the different working states of the product. Nowadays, the functions of desk lamps are becoming more and more diversified, and the backlight patterns of the touch buttons are gradually becoming more complex and intuitive. In order to achieve the backlight effect of the touch buttons as evenly as possibl...
