Embodiment Construction

[0030] The invention will now be described in more detail, embodiments of the present principles are illustrated in the accompanying drawings.

[0031] Figure 5An electronic device 501 is shown with a logo, button or indicator signal component 520, and how this component is positioned in the electronic device 501, which may be a set top box. Assembly 520 includes backlight assembly 511 and integral light pipe structure 523 . The front surface 524 of the light pipe structure 523 is positioned at the aperture 521 of the front wall 9 of the device 501 . The orifice may be associated with a variety of functions, which may include an indicator for a "record" function. Figure 5 It is shown that the component 520 may be positioned near or on a printed circuit board (pcb) 5 . The backlight 11 can be positioned on the pcb 5 and positioned under or behind the light pipe assembly 523 and behind the front wall 9 . The electronic device 501 may include a flange that may have a periph...

Abstract

The present principles are an illumination system for the front of an electronic device such as a set top box. The device includes a casing having a front wall; apertures on the front wall; a backlight assembly in back of the front wall within the casing; and a light pipe structure to receive light from backlight assembly. The light pipe structure includes plurality of light pipes in which the light pipes have a lower vertical body portion, an upper horizontal body portion, and a central body portion between the lower vertical body portion and the upper horizontal body portion; and a bracket that connects and supports the light pipes in which the bracket is generally planar. The bracket has broad support regions that connect to a back portion of each of the light pipes and a narrow bridging region between broad support regions in which the support regions are broader than the narrow bridging region in the vertical dimension.

Description

[0001] cross reference [0002] This application claims priority to US Provisional Application Serial No. 62 / 048408, filed September 10, 2014, which is hereby incorporated by reference in its entirety. technical field [0003] The present principles relate generally to electronic devices and, more particularly, to electronic devices having multiple light pipe structures for illuminating signs, buttons and / or indicator signals. Background technique [0004] Many manufacturers and consumers prefer electronic devices to have logos, buttons, and indicator signals illuminated by light pipe assemblies to allow the product to be identified, the activation button on the product to be identified, and the status of the device to be visually signaled, respectively to the user. [0005] Unfortunately, the lighting of signs, buttons, and indicator signals adds to the cost of the device and also requires some additional volume within the device to be dedicated to supporting the lighting....
