Description

Technical Field

[0001] This utility model relates to the field of integrated power drive technology for four-wire guide rails, specifically to an integrated power drive for four-wire guide rails. Background Technology

[0002] With the development of LED lighting technology, LED lamps have been used in trade, office, and business settings. They are highly bright, provide even light, are aesthetically pleasing, energy-saving, and environmentally friendly. While LED lamps are widely praised, their important component—the driver power supply—is also receiving increasing attention. The quality of the driver power supply directly restricts the reliability of LED lamps.

[0003] An LED driver is a power converter that transforms the power supply into a specific voltage and current to drive the LED to emit light. Typically, the input to an LED driver includes high-voltage AC (mains power), low-voltage DC, high-voltage DC, and low-voltage high-frequency AC (such as the output of an electronic transformer). The output of an LED driver is mostly a constant current source whose voltage changes according to the forward voltage drop of the LED. Currently, most LED power drivers use a single current circuit control method, which prevents the lighting fixtures from providing multiple lighting schemes and makes it difficult to meet the lighting needs of different scenarios.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] In the description of the embodiments of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear, the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] Furthermore, the terms "first," "second," and "third" are used only for distinguishing descriptions and should not be interpreted as indicating or implying relative importance. The use of terms such as "horizontal," "vertical," and "suspended" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be perfectly horizontal, but can be slightly tilted.

[0019] In the description of the embodiments of this utility model, the terms "multiple" or "several" refer to at least two.

[0020] In the description of the embodiments of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] This embodiment is combined with the appendix Figures 1 to 3 This paper provides a detailed description of a four-wire rail integrated power drive.

[0022] This embodiment discloses a four-wire guide rail integrated power drive, including an upper housing 1 and a lower housing 2 that are snapped together and fixed, with an interface 13.
