Embodiment Construction

[0028] Conventional lighting fixtures are often equipped with power supplies that are relatively resistant to power surges or other electrical stresses. However, it may be desirable to provide additional protection for the power supply and / or other electronics in some lighting fixture implementations (conventional or otherwise). For example, some LED-based outdoor lighting fixtures may implement sensitive power supplies, and it may be desirable to implement surge protection in conjunction with such power supplies. However, existing surge protection devices suffer from one or more deficiencies and / or may not be suitable for use with lighting fixtures.

[0029] Accordingly, there is a need in the art to provide a surge protection device that can be implemented in a lighting fixture and that optionally can overcome one or more deficiencies associated with existing surge protection devices.

[0030] The applicant has recognized and appreciated that it would be beneficial to provi...

Abstract

A surge protection device (10, 110) for outdoor lighting fixtures is disclosed that includes a live connection (23A, 123A), a neutral connection (23B, 123B) and a ground connection (23C, 123C). A first varistor (42) and a second varistor (43) may be electrically connected to each other in series connection between live and neutral connections, and a third varistor (41) between live and neutral connections is electrically connected to the first The varistor and the second varistor are arranged in parallel. A surge arrester (46, 146) may also be electrically connected between the ground connection (23C, 123C) and the series connection between the first varistor and the second varistor.

Description

technical field [0001] The present invention generally relates to surge protection. More specifically, the various inventive methods and apparatus disclosed herein relate to a surge protection device that may be employed in lighting fixtures. Background technique [0002] Digital lighting technology, that is, lighting based on semiconductor light sources such as light-emitting diodes (LEDs), presents a viable alternative to traditional fluorescent, HID, and incandescent lamps. Functional advantages and benefits of LEDs include high energy conversion and optical efficiency, durability, low operating costs, and more. Recent developments in LED technology have provided efficient and robust full-spectrum light sources that support a variety of lighting effects in many applications. [0003] Traditional fluorescent, HID, and incandescent lighting fixtures are often equipped with power supplies that are relatively resistant to power surges or other electrical stresses. However,...
