Electronic display device with integrated lighting system

Priorities and related applications

The present application is directed to US Provisional Application No. 61 / 072,475, filed Mar. 31, 2008, entitled "Computer Display Work Lighting System Method And Apparatus," Claiming priority of US Provisional Application No. 61 / 208,291, filed Feb. 23, 2009, entitled "Display With Integrated General Lighting System Method And Apparatus". The contents of the present applications are incorporated herein by reference.

The present invention provides a table lamp and a floor lamp; Work lights; Advertising frame; And portable or semi-portable lighting devices and fixtures for general lighting, such as track lighting, and also digital photo albums; Desktop and portable computers; And portable or semi-portable electronic visual display devices such as plasma and liquid crystal (LCD) television displays.

Electronic visual displays are electronics such as televisions, laptops and desktop computer monitors, portable DVD players and photo or image display devices that display pictures on frames, which are used to display information and entertainment content to consumers in the modern world. will be. Generally such displays use liquid crystal and plasma technology. One problem associated with such displays is straining the eyes when inadequate illumination is provided in the light output and / or visible area of the display.

Table lamps, floor lamps, advertising frames and track lighting are preferred forms of general lighting intended to provide useful amounts of light (generally 100 lumens or more) to support the intended activity. A consumer product having an electronic visual display for providing good viewing and / or working or navigational lighting of a display, wherein such area or area illuminators (often portable) are used in the same area or even on the same surface. Frequently used. The useful space required for both products is an issue for the intended use of the products and for other uses to be provided in the space.

In addition, the optimal illumination of the area is functionally or aesthetically conflicted by the two devices, both spatially and positionally, and compromised by their independent design. For example, a shadow (caused by the display) will be present on the right side of the display if the table top lamp is located on the left side of the display, and the shadow for the lamp will direct light to the area behind the display if necessary. Lamps with clamp-on or other common connectors may be temporarily fixed but will not be aesthetically pleasing and will not conform to a suitable cooperative surface for fixing stability.

In addition, power requirements are an issue, as main outlets are separated by most municipal laws and both products (lights and displays) require a connection to the main outlet. If both products are "plugged in," a typical outlet is insufficient to connect other products to the power supply.

Consumers sometimes rely on light coming from a display (especially integrated into a television system) for navigation lights and possibly even some work lights.

In all embodiments, the housing 14 has a front face 14a, a back face 14b, a left face 14c, a right face 14d, a top 14e and a bottom 14f. The housing 14 generally surrounds and protects all internal components employing the display for the special use of the electronic visual display 12 (eg, television, computer interface / monitor or digital picture frame).

The front face 14a of the housing 14 includes a display screen 20 in which the displayed content is visible. In embodiments such as televisions and computers, this display screen 20 is part of information, entertainment or user interface content.

The lighting devices 16 are integrated with the housing 14. As used herein, the term "integrated / integrated" means that the lighting devices are mounted in a suitable manner known to those skilled in the art, regardless of the form of the light (e.g. LEDs or incandescent lamps) and the housing ( The parts of 14 and the lighting devices 16 are configured to cooperate with one another in order to enable safe mounting and attachment to one another in a manner that allows for a relatively convenient and relatively aesthetically acceptable consumer package. It means to be shaped. The safety here means an attachment that withstands normal impact during use and in some cases means resistance to the helpless removal of the tool. Integration may include the molding or shaping of certain surfaces or grooves in the housing to fit and accommodate the lighting devices for safety. Integration does not exclude the use of fasteners such as screws, rivets or glues, nor does it exclude press fit and snap fit configurations. However, integration does not mean lighting devices in which bulbs or other subcomponents do not need to be assembled by a consumer or product dealer. The lighting devices 16 are integrated or mounted in a manner that allows the orientation of the lighting devices 16 to provide direct sunlight to one or more spaces outside the electronic image display 12 and the housing 14. Direct light means light (or beam of light) in the direct line of the site of the light generating device, ie unbiased light.

As is known in the art, the electronic visual display 12 and its complementary components, for example for a television or desktop computer, include an on state and an off state. These states may be generally selected by the end user or consumer using the system 10. However, according to an embodiment of the present invention, the display system 10 provides an on state and an off state that are independently controlled with respect to the lighting devices 16. In other words, the on and off states of the lighting devices 16 are selected independently of the on and off states of the electronic visual display 12 and its associated components. . In this arrangement, the system 10 can function as a general lighting device. Thus, when the user turns off the image display device 12, the user may choose to leave the lighting devices 16 as general lighting or task lighting depending on the number, location and orientation of the lighting devices 16. This feature can provide consumers with more secure location and convenience. It can also fulfill the function of a general lighting device (providing light), which functions independently of the visual display. Preferably this is achieved without securing the space required by a separate lighting device such as a lamp.
