Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 to 2, the present application provides an LED light emitting assembly 10, where the LED light emitting assembly 10 is applied to a lamp 100, the LED light emitting assembly 10 includes LED beads 11 and a substrate 12, and the LED beads 11 are welded and fixed on the substrate 12.

The substrate 12 is in a long strip shape, the substrate 12 has a length direction (e.g., an X direction in fig. 1) and a width direction (e.g., a Y direction in fig. 1), the length direction and the width direction of the substrate 12 are perpendicular to each other, the number of the LED lamp beads 11 is multiple, the LED lamps are arranged at intervals along the length direction of the lamp strip, and the distance between two adjacent LED lamp beads 11 is set according to actual needs, which is not described herein. In some embodiments, the substrate 12 is flexible, and the substrate 12 can be rolled and bent to facilitate transportation and packaging of the LED lighting assembly 10.

In this embodiment, the LED lamp bead 11 is a patch soldered on the substrate 12. A plurality of pairs of first welding pads for welding and fixing the LED lamp beads 11 are arranged on the substrate 12. The LED lamp bead 11 is provided with two lamp feet, and each lamp foot is welded with the corresponding first welding disc respectively.

When the lumens or color temperatures of the LED beads 11 in the LED lighting assemblies 10 of different models are different and the LED lighting assemblies 10 are not marked, an operator distinguishes the LED lighting assemblies 10 and the distinguishing is cumbersome, for example, distinguishing is performed by an external detection device, which easily causes overstock of the inventory.

In order to solve the above technical problem, in this embodiment, as shown in fig. 1 to fig. 2, a plurality of marks 124 corresponding to the models of the LED lighting assemblies 10 one by one are printed on the substrate 12, and an electronic component indicating the model of the LED lighting assembly 10 is welded near one of the marks 124.

Through the electronic components near the mark 124, the model corresponding to the LED lighting assembly 10 is determined, and the mark 124 can rapidly distinguish the model of the LED lighting assembly 10, so as to reduce the labor cost.

In the present embodiment, the electronic component is a chip mounted on the substrate 12. The substrate 12 is provided with a second pad 125 for soldering an electronic component. In order to more rapidly distinguish the marks 124 corresponding to the electronic components, in some embodiments, a second pad 125 for soldering the electronic components is disposed near each mark 124. In some embodiments, the electronic component is a resistor. The resistance is more conspicuous, further facilitating operator differentiation of the corresponding indicia 124.

The number of markers 124 is at least two, including two and more. In the present embodiment, the indication 124 is a color temperature value and/or a lumen value of the indication 124. For example, when the number of the markers 124 is three, the markers 124 are (3000K, 460LM), (4000K, 480LM), and (6500K, 480LM), respectively. When the LED light emitting assembly 10 is a product of (3000K, 460LM), a resistor needs to be soldered to the second bonding pad 125 near (3000K, 460 LM); when the LED light emitting device 10 is a product of (4000K, 480LM), it is necessary to solder a resistor on the second pad 125 near (4000K, 480 LM); when the LED light emitting module 10 is a product of (6500K, 480LM), it is necessary to solder a resistor to the second pad 125 near (6500K, 480 LM).

When the mark 124 and the LED lamp beads 11 are sequentially arranged along the width direction of the substrate 12, the width of the substrate 12 may be increased, or the mounting positions of the LED lamp beads 11 on the substrate 12 may be affected. In order to solve the technical problem, in some embodiments, the marks 124 and the LED beads 11 are sequentially arranged along the length direction of the substrate 12, so that the substrate 12 has enough space to arrange the marks 124.

The location of each marker 124 on the substrate 12, and with reference to one embodiment, each marker 124 is disposed sequentially along the length of the substrate 12. Of course, in other embodiments, each indicia 124 is disposed sequentially along the width of the substrate 12.

In the configuration of the substrate 12, referring to one embodiment, as shown in fig. 5, the substrate 12 includes a metal layer 121, an insulating layer 122, and a circuit layer 123, and each pad is electrically connected to the circuit layer 123. The substrate 12 may be a metal substrate 12, preferably an aluminum substrate 12, or an FR-4 glass fiber board. In some embodiments, the surface of the substrate 12 is coated with a solder resist ink layer, and the solder resist ink layer is white on the side of the substrate 12 facing the LED lamp bead 11, so as to improve the light reflection efficiency. The solder resist ink layer is provided with a window at the pad to allow the pad to leak.

As shown in fig. 1 to 5, the present application further provides a lamp 100, which includes a lamp tube 30, end caps 20 fixed at two ends of the lamp tube 30, a light bar installed in the lamp tube 30, and a driving power source 40 installed in the lamp tube 30 and electrically connected to the light bar. The driving power source 40 is connected to the LED lighting assembly 10 through a wire. The light bar adopts the LED light-emitting component 10 in the above embodiments.

The lamp tube 30 has a length direction (e.g., Z direction in fig. 4), the lamp tube 30 is disposed in a hollow manner, and two ends along the length direction are disposed in an open manner, the LED light emitting assembly 10 and the driving power source 40 enter the lamp tube 30 from one end of the lamp tube 30, and are fixedly mounted in the lamp tube 30 by means of bonding or the like, and finally, the two ends of the lamp tube 30 are sealed by the end caps 20. In the present embodiment, the cross section of the lamp tube 30 is circular, and the end cap 20 is sleeved on the outer side of the end of the lamp tube 30; the lamp tube 30 is made of glass.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features. When technical features in different embodiments are represented in the same drawing, it can be seen that the drawing also discloses a combination of the embodiments concerned.
