Light emitting diode light-emitting device

Abstract

The invention discloses a light emitting diode (LED) light emitting device. The device comprises a lighting slab structure with a plate shaped soft base material and a current stabilizing circuit in electric connection with the lighting slab structure, wherein the plate shaped soft base material is provided with a flexible conductive structure; the flexible conductive structure is provided with at least one pluggable LED bulb; and the current stabilizing circuit is used for eliminating noise of an external power supply by an electromagnetic interference filter, rectifying AC to DC by a primary side rectifying filter, converting output DC to secondary side by a transformer to output rectifying filter, generating an isolating function of the primary side rectifying filter to the secondary side output rectifying filter, carrying out flyback power conversion, converting the secondary side output rectifying filter of the transformer to a DC output power supply, controlling supplied voltage and current, providing stable voltage and current output, and controlling frequency of the flyback power conversion part by a pulse width modulator so as to process energy control of an output part.

Description

technical field [0001] The present invention relates to a light emitting device, in particular to a light emitting diode (LED, Light Emitting Diode) light emitting device. Background technique [0002] In order to attract people's attention, general commercial business places or government agencies often set up signboards or billboards in conspicuous places. It can also be eye-catching to achieve the effect of attracting attention. There are already many signboards or billboards equipped with light-emitting devices, and the light-emitting devices are used to achieve eye-catching publicity or advertising effects such as font representation and pattern display. [0003] The luminous devices used in the above-mentioned signboards or kanbans with luminous devices include fluorescent lamps, neon lights, general light bulbs, and LED light bulbs. Because LEDs have the characteristics of low heat generation and energy saving, and they can be controlled by a computer in a dot matrix ...

AI Technical Summary

Problems solved by technology

[0004] However, in the structure of the existing LED light-emitting devices, a wire group is used to directly connect multiple LED bulbs in series to form a long light string, and the electrical connection between the LED bulbs and the wires is usually welded or wound. Therefore, If one of the LED bulbs burns out, the user must replace the entire set of LED lighting devices, or notify a professional to replace a single LED bulb, so it is very troublesome and inconvenient to maintain.

[0005] Furthermore, when designing the above-mentioned signboards or kanbans with LED lighting devices, the manufacturer must first design patterns according to the needs of users, and then embed the above-mentioned series-connected LED lighting devices on the designed pattern. The position of the LED bulb on the device has been fixed, and the pattern has also been finalized. When the user wants to change the pattern, it must be designed by the manufacturer and cannot be changed by himself, which will cause cost overhead. Therefore, the existing LED light The device is also greatly limited in the degree of freedom of pattern replacement and does not conform to economic benefits

[0006] Also, although the prior art proposes the setting position of the bulb that can be freely replaced and the related structure of a more maintainable LED lighting device, such as Taiwan's new No. M322624 "light-emitting diode light-emitting plate structure", Taiwan's new No. M322501 "LED However, when the LED bulb burns out and the LED bulb needs to be replaced, other normal LED bulbs will flicker when they are in use, or after maintenance and replacement of a new LED bulb, due to poor contact As a result, the entire group of LED light-emitting devices cannot be turned on, so there is still room for improvement in the structure.

[0007] Furthermore, the existing LED lighting devices, such as luminous boards and other kanbans or signboards, all have a considerable size. After the manufacturer completes the production, the kanban or signboards with a certain size are not very easy to transport, and the transportation process is very difficult. In the process, it is very likely that collisions will occur due to its large size, which will cause damage to the LED lighting device on the kanban or signboard, resulting in the inability to produce a luminous effect when transported to the site. Therefore, how to make the LED lighting device for kanban or signboard Can be easily Transportation is also the direction that manufacturers of LED lighting devices are actively developing and improving
