Description

LED lighting equipment

Technical Field

The application belongs to the technical field of LED lighting equipment, and particularly relates to detachable LED lighting equipment.

Background

LEDs have the advantages of environmental protection, energy saving, high efficiency and long service life, and are therefore generally paid attention in recent years, and gradually replace the place of the conventional lighting fixtures. However, the light emitted by the conventional LED light source has directivity, unlike the conventional lamp, which can illuminate in a wide-angle range, so that the application of the LED to the conventional lamp has corresponding challenges depending on the type of the lamp.

In the prior art, the LED lighting equipment adopts LED lamp beads as basic lighting units, the LED lamp beads are distributed according to a certain rule or according to a certain design requirement to form a complete light source, wherein the LED lamp beads are distributed at intervals along a certain direction to form a strip-shaped LED lamp bead array which is of a relatively common design, the LED lamp bead arrays are distributed in the same direction or in different directions to extend on the basis, and some special distribution designs can achieve unexpected effects on the light emitting effect and the light pattern.

In the existing design, in order to pursue the firmness of product connection, a connection structure in the LED lighting device is generally designed into a structure which is difficult to disassemble once connection is completed, such as a screw structure, a rivet structure, a welding structure, gluing and the like, and after the fixing of the components is completed, special tools or special means are required for disassembly, and furthermore, the disassembly process is destructive, which brings great trouble to the later maintenance of the LED lighting device. In the LED lighting device, components which are relatively easy to be damaged are usually components related to light emission and components related to circuit conduction, and the components are generally attached to structural members of the LED lighting device in the existing design and are fixed or covered by the structural members, the fixing and covering are usually realized through the screw structures, the rivet structures, the welding structures, the adhesives and the like, and the components in the LED lighting device are firmly fixed by the structures, and meanwhile, the components are bound, so that the components are time-consuming and labor-consuming to replace when a problem occurs or adjustment is needed, and the components are also in the assembly and disassembly.

In the existing design, the light-emitting surface of the LED lighting device is single, and only one light-emitting surface is usually provided, so that obvious dark areas possibly exist in other directions, and the lighting effect of the LED lighting device is affected.

In the existing design, the light source is generally designed by arranging the light source monomer on a substrate, such as an FPC, a circuit board or other materials, and the light emitting direction of the light source monomer is set to deviate from the substrate, so as to form a single-sided (unidirectional) light emitting light bar, and the light bar is arranged on the LED lighting device to conduct and emit light, and has larger limitations on the light emitting direction and the light emitting angle.

In the existing design, the light source of the LED lighting device is generally a complete whole or is distributed in a relatively concentrated area to realize light, but because the light source is used as a main working element of the LED lighting device, the light source needs to be electrified and lightened for a long time in the long-term use process, and the service life of the LED lighting device is affected by a series of factors including aging of a circuit, heating, service life of the LED lighting device and environmental influence (such as short circuit caused by humidity) so that the LED lighting device cannot be lightened or can not meet the original illumination requirement in certain situations, and the whole light source or the whole LED lighting device needs to be disassembled and overhauled in replacement or maintenance, so that the problem investigation is difficult, the maintenance is time-consuming and labor-consuming, and the long-term maintenance and the use of the LED lighting device are not facilitated.

In summary, in view of the defects and drawbacks of the LED lamp in the prior art, how to design the LED lamp to reduce the difficulty in assembling and disassembling the LED lamp, reduce the maintenance cost, improve the production efficiency, and improve the light emitting effect is a technical problem to be solved by those skilled in the art.
