Abstract
The utility model relates to a light-emitting diode (LED) light strip and an LED glass display screen and belongs to the technical field of display devices. The light strip comprises a strip-shaped printed board. A drive element is arranged on the back of the printed board, a group of luminous tubes are arranged on the front of the printed board along the length direction, and two side edges of the printed board respectively and symmetrically extend out of bosses along the width direction on each luminous tube and respectively form bottom faces of the corresponding bosses. Hollow portions are formed between neighboring bosses, the bottom faces of the bosses are the same side edges of the printed board, and the hollow portions are matched with the shape of at least one of the bosses on two sides of the hollow portions. Outer edges of each boss exceed those of the corresponding luminous tubes or are in parallel with those of the corresponding luminous tubes. By adopting the LED light strip and the LED glass display screen, when single printed boards are divided from a whole printed board, almost no offcut is produced, and therefore production efficiency is improved and production cost is reduced beneficially. In addition, the display screen is high in light transmittance and especially suitable for being used indoors or on lighting faces of buildings.
Description
Technical field
The utility model relates to a kind of LED lamp bar and contains the LED glass display screen of this lamp bar, belongs to the display device technical field.
Background technology
Understand according to the applicant, LED shows that industry is with rapid changepl. never-ending changes and improvements, and product is constantly weeded out the old and bring forth the new.Because LED display itself has changeability, therefore go among all kinds of occasions.Conventional LED display is in order to improve contrast, usually adopt the face shield of black to improve contrast, but when needs were used for indoor or lighting for buildings face, the face shield of black was difficult to printing opacity and can brings the sensation that the people constrains, and is unfavorable for that indoor occupant carries out routine work.
Find through retrieval, publication number is that the Chinese invention patent application of CN101477771A discloses a kind of LED display glass curtain wall, and light transmission is good, can solve above-mentioned daylighting problem.But in this display screen, the printed board of LED lamp bar is in the circle that is shaped as at lamp point place, and circular difficulty of processing is higher; In addition, as shown in Figure 1, adopt circular configuration, when cutting, be difficult to effectively utilize the monoblock printed board, each independent printed board 1 ' between can produce more leftover bits 2 '.These all are unfavorable for enhancing productivity and reducing production costs.
The utility model content
The purpose of this utility model is: for the problem that above-mentioned prior art exists, propose a kind ofly can effectively utilize the monoblock printed board, can produce the LED lamp bar of leftover bits hardly, be conducive to enhance productivity and reduce production costs; Propose simultaneously a kind of LED glass display screen that contains this lamp bar, light transmittance is high.
In order to reach above purpose, LED lamp bar of the present utility model, comprise that the back side is mounted with the bar shaped printed board of driving element, described printed board front is mounted with one group of luminous tube of arranging along its length, it is characterized in that, the dual-side of described printed board at each luminous tube place respectively broad ways extend boss towards external symmetry, the dual-side of described printed board consists of respectively the bottom surface of corresponding boss; Take the same side of described printed board as forming depression between the adjacent lands of bottom surface, described depression is coincide with the shape of one of this depression both sides boss at least; The outward flange of described each boss exceeds corresponding luminous tube outward flange or concordant with corresponding luminous tube outward flange.
After adopting the utility model structure, when being partitioned into single printed board from the monoblock printed board, coincide because the concavo-convex profile of the concavo-convex profile of a printed board and adjacent printed board is complementary, can produce leftover bits hardly after cutting apart, be conducive to enhance productivity and reduce production costs.
The utility model also proposes to contain one group of as previously mentioned LED glass display screen of LED lamp bar.This display screen light transmittance is high, is particularly useful for indoor or the lighting for buildings face.

The specific embodiment
The LED lamp bar basic structure of the present embodiment such as Fig. 2 are to shown in Figure 5, comprise that the back side is mounted with the bar shaped printed board 1 of driving element 3, printed board 1 front is mounted with one group of luminous tube of arranging along its length 2, the dual-side of printed board 1 at each luminous tube 2 place respectively broad ways extend boss 1-1 towards external symmetry, the dual-side of printed board 1 consists of respectively the bottom surface of corresponding boss 1-1; Take printed board 1 same side as forming depression 1-2 between the adjacent lands 1-1 of bottom surface, depression 1-2 coincide with the shape of one of this depression both sides boss 1-1 at least; The outward flange of each boss 1-1 exceeds corresponding luminous tube 2 outward flanges or concordant with corresponding luminous tube 2 outward flanges.In addition, an end of printed board 1 is provided with the cable 4 that is electrically connected with external power source and control device overleaf.
When being partitioned into single printed board from the monoblock printed board, coincide because the concavo-convex profile of the concavo-convex profile of a printed board and adjacent printed board is complementary, can produce hardly leftover bits (as shown in Figure 5) after cutting apart.After adopting said structure; when producing the lamp bar, can in the monoblock printed board, scribe V-shaped valley by each single printed board profile first; then in whole printed board, mount luminous tube and driving element in the Reflow Soldering mode by chip mounter; the V-shaped valley that fractures at last namely obtains single lamp bar, thereby accomplishes scale production.
Boss 1-1 is cuboid or truncated rectangular pyramids, can reduce difficulty of processing.
The preferred end face of boss 1-1 and end face length parallel with the bottom surface is greater than the symmetrical truncated rectangular pyramids of incline length.Because the hot spot ovalize that sends of LED luminous tube is dispersed, the boss outward flange then is within the hot spot when adopting this structure, makes spectators see luminous point and can't see boss, is conducive to further guarantee display effect.
Printed board 1 surface is provided with white coating, can improve the penetrating sense of lamp bar.
The present embodiment contains the LED glass display screen of one group of embodiment, 1 described LED lamp bar such as Fig. 6 to shown in Figure 10.Because adopted the LED lamp bar of embodiment 1, the present embodiment display screen light transmittance is high, is particularly useful for indoor or the lighting for buildings face.
The present embodiment display screen also comprises the front panel 6 of being made by transparent material (such as glass), each LED lamp bar 7 is positioned at front panel 6 the same sides and is parallel to each other, the luminous tube 2 of each LED lamp bar 7 is towards front panel 6, front panel 6 is fixed on a side of framework 5, and the two ends of each LED lamp bar 7 are connected through connector 10 and framework 5 respectively.Because this is relatively simple for structure, be easy to make, be conducive to enhance productivity and reduce cost.
In the present embodiment, framework is made of at least two column 5-1.Column 5-1 inside is provided with power supply 8 and control system plate 9, and each LED lamp bar 7 has the cable 4 that is electrically connected with power supply 8 and control system plate 9 respectively.Like this can power supply and control device is hidden, make the display screen outward appearance more neat.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
