Detailed Description
The present invention will be described in further detail below with reference to the accompanying drawings by way of specific embodiments. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. Furthermore, the technical features mentioned in the embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
Referring to fig. 1 to 2, a knob lighting structure of a light guide plate is shown, which can be used for operation panels of systems such as aviation, aerospace, shipboard, weapons, etc.
The illumination structure mainly comprises a light guide panel 1, a knob body 2, a light-transmitting sign 3, a light source printed board 4 and the like.
The light guide panel 1 is made of metal materials and plays a role in blocking light. The light guide panel 1 has a panel top wall 11 and a panel peripheral wall 12. The panel top wall 11 and the panel peripheral wall 12 together define a panel accommodating chamber. The panel accommodating chamber can accommodate a potentiometer, a control circuit board and the like. The panel top wall 11 is formed with a top wall center hole 111 and a top wall side hole 112 beside the top wall center hole 111.
The knob body 2 has a knob cap 21 and a knob shaft 22. The knob cap body 21 is made of a light-transmitting material. The knob cap 21 is disposed above the panel top wall 11. A knob scribed line is formed on the knob cap body 21 and corresponds to the top wall side hole 112 up and down. The knob shaft 22 is fixedly connected to the rotating cap. The knob shaft 22 downwardly passes through the top wall center hole 111 and extends to the interior of the panel receiving chamber.
The light-transmitting label 3 is disposed at the upper end of the top wall side hole 112. The light-transmitting sign 3 is made of a light-transmitting material. The bottom surface of the light-transmitting sign 3 is provided with a light-incoming surface which is a paraboloid or an arc surface. A light-emitting surface is formed on the top surface of the light-transmitting sign 3, and the light-emitting surface is a plane. The purpose of the above design is to convert the divergent incident beam into parallel or approximately parallel transmitted beam, and improve the illumination brightness and uniformity. In this embodiment, the transparent sign 3 is made of night-vision green organic glass and has a thickness of 1-1.5 mm.
The light source printed board 4 is disposed at the lower end of the top wall side hole 112. The light source printed board 4 is provided with an LED light source, and the emitting direction of the LED light source is upward. Preferably, the LED light source is a high-brightness or ultra-high-brightness LED. A certain gap is reserved between the light source printed board 4 and the light-transmitting label 3, so that the LED light source is convenient to illuminate.
Further, the top wall side hole 112 is a two-step stepped hole. The top wall side aperture 112 has a side aperture upper section 1121 and a side aperture lower section 1122. The inner diameter of the side hole upper section 1121 is smaller than the inner diameter of the side hole lower section 1122. The light-transmitting sign 3 is formed in the upper portion of the side hole upper section 1121 and the side hole lower section 1122. The top surface of the light-transmitting sign 3 is flush with the top surface of the panel top wall 11. The light-transmitting sign 3 is adhered to the inner circumferential surface of the side hole upper section 1121, the top surface of the side hole lower section 1122 and/or the inner circumferential surface of the side hole lower section 1122. The light source printed board 4 is formed in the lower portion of the side hole lower section 1122. The bottom surface of the light source printed board 4 is flush with the bottom surface of the panel top wall 11.
The working process is as follows: the LED light source of the light source printed board 4 emits a light beam upward. The light beam enters the knob cap 21 through the light-transmissive sign 3 to exclusively illuminate the knob score line.
The above description is only for the embodiment of the present emergency new model, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the utility model. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
