Description

Technical Field

[0001] The utility model relates to the technical field of LED lighting, in particular to a junction box and a lighting fixture with the junction box. Background Art

[0002] With the development of science and technology and the improvement of economic level, people's demand for spiritual culture is constantly increasing, and the diversification and multi-colorization of LED lamps are also emerging in more and more occasions. In terms of architectural landscape lighting, several strip LED lamps are usually connected in series, sharing the same power supply to achieve the lighting effect of LED lamps in series. By intermittently turning on and off the lighting beads, the diversification of lighting colors and patterns is achieved. As a form of urban lighting beautification products, it appears in front of the people, giving people more spiritual enjoyment and visual impact.

[0003] In terms of lighting control technology, the strip LED lamp is equipped with a light board inside the lamp body. The light board is welded to the integrated control circuit through several wires. The integrated control circuit controls the lighting of the LED lamp beads on the light board and supplies voltage.

[0004] The existing integrated control circuit is exposed inside the lamp housing of the LED lamp, which not only occupies the internal space of the lamp, but also generates heat inside the lamp housing when it is working. During the alternating process of hot and cold, it is easy to condense to form water vapor, which adheres to the lamp board or the integrated control circuit, causing a circuit short circuit fault;

[0005] The integrated control circuit also undertakes the task of connecting the power supply and signals between the strip LED lamps, which increases the number of power jumpers and signal jumpers between the lamp board inside the lamp housing and the integrated control circuit. The jumpers are interspersed and complicated, which brings structural interference on the light beam of the LED lamp, affects the normal irradiation of the light beam, and greatly reduces the light beam effect.

[0006] In addition, due to the increase of power jumpers and signal jumpers between the light board and the integrated control circuit, the number of welding points increases, which easily causes cold welding and greatly reduces the yield rate.

[0007] Therefore, there is an urgent need to provide a junction box and a lighting fixture having the junction box that overcome the above problems. Utility Model Content
