Description

TECHNICAL FIELD

[0001] The present application relates to a connector used in the field of LED lighting; in particular, it relates to a universal connector compatible with Zhaga standard bases. BACKGROUND

[0002] With the development and iteration of technology, light emitting diodes (LEDs) have completely changed indoor and outdoor lighting, and with the gradual development of home intelligence, intelligent lighting has also emerged as the times require. This solid state lighting (SSL) technology has excellent efficiency, controllability, color spectrum, thermal performance, and unique appearance. At present, most indoor and outdoor lighting designs and upgrades of existing designs will first consider LEDs. LED lighting not only completely changes the light source itself, but also changes the design and appearance of connectors and lamps, which are essential components of lighting systems, especially for lighting, and as a key link of smart home or office, to provide intelligent, energy-saving, and high-performance lighting.

[0003] Zhaga is an international alliance of LED lighting industry cooperation organizations, aiming to develop interface standards for LED lamp components, and to define interfaces and specifications for various application light engines, to achieve the convenient exchange of LED light sources produced by different manufacturers, to avoid the market division caused by incompatible and non-interchangeable products, and to benefit consumers and light engine purchasers. Zhaga specifications cover the geometric dimensions of LED light engines and their optical, mechanical, electrical, and thermal characteristics. The formal name of Zhaga specification is Book (specification), which is aimed at electrical, mechanical, optical, thermal, and communication interfaces, and allows the interoperability of components. By complying with Zhaga specifications, designers can ensure that users have interoperable, replaceable, or repairable components, and ensure that LED lamps can be upgraded after installation when new technologies appear. Book 18 is a standard interface specification focusing on outdoor LED lighting, which is an "intelligent interface between outdoor luminaires and sensors / communication modules". This standard defines an intelligent luminaire interface, including mechanical sockets, communication, and control, so that sensors / communication modules can be installed outside the luminaire in a "plug and play" manner, similar to the USB port on a computer. It specifies mechanical fit and electrical pin parameters of the connection system, simplifies the addition of application modules such as sensors and communication nodes to LED luminaires, and ensures plug-and-play interoperability, which has been widely supported by connectors, providing flexibility for users in different scenarios.

[0004] In addition to the above Zhaga Book 18 standard interface, there is also a Z10 standard interface on the market. The Z10 standard interface is different from the Zhaga Book 18 standard interface in terms of shape / size of the center guide positioning column / hole (see the attachedFigure 1 and attached Figure 2 Therefore, the existing two kinds of standard interface connectors cannot be compatible, cannot be universal, and can only be connected with the base of the respective standard interface, resulting in that the two kinds of standard connectors in the market are independent and cannot be exchanged, and the convenience of use of users is affected.
