Dislocation formula lamp body and lamp plate

Technical Field

The invention relates to the technical field of LEDs, in particular to an offset lamp body and a lamp panel.

Background

In the LED display screen industry, a lamp body is one of the core components, and the lamp body is arranged on a plate in a combined manner, and is uniformly wired and power-supplied to form a lamp panel. The surface-mount three-in-one standard lamp body has become a main application, and in consideration of the wiring and the process of the lamp body in general conditions, the arrangement mode of the monochromatic lamps at the upper end of the standard lamp body corresponds to the pin positions corresponding to each other in the vertical direction one by one (as shown in the structures of fig. 1 and 2, the structure is understood according to the difference of figures), that is, the monochromatic lamps vertically corresponding in space are directly and electrically connected with the pins, and the color driving signal pins at the bottom of the lamp body correspond to the same color as the light emitting surface of the lamp.

However, such a standardized lamp body package format, which is unified, may not be suitable in some situations. For example, when the lamp surface layout is performed, in order to ensure uniform uniformity of the light emitting surface of the lamp, the same column driving signal pins among the standard lamp bodies are necessarily arranged at intervals, and accordingly, the pins need to be connected on the lamp surface by bypassing the bonding pads, so that the space for wiring is relatively limited, and safe wiring is difficult. And if the via hole is drilled to change layers and is connected, the via hole can occupy the whole space, the design of the plate is difficult to complete, and the difficulty of the development of the lamp panel is improved.

Disclosure of Invention

The invention aims to provide a dislocation type lamp body and a lamp panel, and aims to solve the problems that wiring is difficult when a plurality of lamp bodies are arranged on the lamp panel in the prior art, and the development difficulty of the lamp panel is high due to the fact that the number of via holes is large.

The staggered lamp body is characterized in that a plurality of light-emitting parts are arranged at the upper end of the staggered lamp body, external pins are correspondingly arranged at the lower end of each light-emitting part in the vertical direction, each light-emitting part comprises a first monochromatic lamp, a second monochromatic lamp and a third monochromatic lamp which are sequentially arranged in the clockwise direction, each external pin comprises a first pin, a second pin and a third pin which are correspondingly arranged in the clockwise direction, the first pin is electrically connected with the second monochromatic lamp, the second pin is electrically connected with the third monochromatic lamp, and the third pin is electrically connected with the first monochromatic lamp; or

The first pin is electrically connected to the third monochromatic lamp, the second pin is electrically connected to the first monochromatic lamp, and the third pin is electrically connected to the second monochromatic lamp.

Compared with the prior art, the staggered lamp body has the advantages that the structure of the light emitting parts is the same as that of a standard lamp body, the distribution mode of the pins outside the lower end is changed, the pins and the light emitting parts do not follow the corresponding relation in the vertical direction, but are connected to other adjacent light emitting parts in a staggered mode, when the staggered lamp body is assembled, the staggered lamp body is arranged adjacent to the standard lamp body, the pins which are originally distributed at intervals can be close to each other due to the fact that the pins outside the staggered lamp body are staggered, the pins are directly wired and connected on the lamp surface and share the via hole changing layer, the via hole density is greatly reduced, and the lamp panel is easy to develop and.

The invention also discloses a lamp panel, which comprises the standard lamp body and the dislocation type lamp body, when the standard lamp body and the dislocation type lamp body are arranged adjacently on the lamp panel, the pins can be close to each other, wiring is easy, and the design difficulty of the lamp panel is reduced.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The implementation of the present embodiment is described in detail below with reference to specific drawings.

As shown in fig. 2 to 4, the present embodiment provides an offset lamp body 1, which has a plurality of light emitting elements at an upper end and a plurality of external pins at a lower end, wherein each light emitting element corresponds to one external pin in a vertical direction. According to the sequence of arrangement, the light-emitting member comprises a first monochromatic lamp 111, a second monochromatic lamp 112 and a third monochromatic lamp 113 which are sequentially arranged along the clockwise direction, the external pins comprise a first pin 121, a second pin 122 and a third pin 123 which are correspondingly arranged along the clockwise direction, and in the vertical direction, the first monochromatic lamp 111 corresponds to the first pin 121, and so on.

The connection relationship between the external pins and the light emitting element does not correspond to the connection relationship in a spatial manner. Specifically, there may be two connection ways:

(1) the first pin 121 is electrically connected with the second monochromatic lamp 112, the second pin 122 is electrically connected with the third monochromatic lamp 113, and the third pin 123 is electrically connected with the first monochromatic lamp 111;

(2) the first pin 121 is electrically connected to the third monochromatic light 113, the second pin 122 is electrically connected to the first monochromatic light 111, and the third pin 123 is electrically connected to the second monochromatic light 112.

I.e., in a clockwise or counterclockwise direction, the external leads and the glowing member are misaligned.

As shown in fig. 1 and fig. 2, the relationship between the external pin and the light emitting element can be distinguished by different patterns, and the corresponding connection manner between the external pin and the light emitting element in this embodiment corresponds to 90 ° counterclockwise rotation.

The benefit of the offset connection is that the actual corresponding external pin position of each light emitting element can be changed. Like the mode shown in fig. 3, when designing lamp plate 3, dislocation formula lamp body 1 and 2 intervals of standard lamp body set up, under the prerequisite that does not change each illuminating part position, make originally alternately the pin of arranging lean on together, directly walk the line at the lamp face and link to each other to a via hole commutation layer of sharing, greatly reduced via hole density, make lamp plate 3 design simple more swift, finally reduce the 3 development difficulties of lamp plate.

As shown in fig. 2 and fig. 3, a power supply position 114 is reserved at the upper end of the dislocation lamp body 1, a power supply pin 124 is further arranged at the lower end, the power supply pin 124 and the power supply position 114 are also arranged in a dislocation manner in the vertical direction, so that the dislocation manner of the light emitting element and the external pin can be referred to, and the dislocation is performed clockwise or counterclockwise, thereby achieving similar technical effects, and the specific content is not repeated.

As shown in fig. 3, the present embodiment further provides a lamp panel 3, which is provided with a plurality of standard lamp bodies 2 and a plurality of offset lamp bodies 1. Because standard lamp body 2 and dislocation formula lamp body 1 have different pin arrangement, changed the mode that the pin interval set up among the prior art, make to walk the line convenient, reduced the development degree of difficulty of lamp plate 3.

On the lamp plate 3 in this embodiment, the standard lamp bodies 2 and the dislocation lamp bodies 1 are arranged at intervals, and can be arranged at intervals between rows or between columns according to the actual dislocation direction and the installation wiring requirement of the dislocation lamp bodies 1, so that the pins of the adjacent standard lamp bodies 2 and the dislocation lamp bodies 1 are close to each other, and the wiring is convenient.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
