Description

Fan-shaped colorful light-emitting diode combinations structure

Technical field

The utility model relates to a kind of light-emitting diode (LED), specifically, relates to the shape of the encapsulation tube cross section of colorful light-emitting diode.

Background technology

The boundless universe, red, orange, yellow, green, blue, blue, purple are a splendid legacy.Along with improving constantly of the fast development of LED technology and people's living standard, esthetic sentiment, a kind of color LED display screen is shown one's talent; Because its fineness, display effect true to nature more and more are subjected to people's favor, and obtained to use widely.

The color LED display screen is spliced by several color LED lattice modules, the color LED lattice module again by colorful light-emitting diode, circuit board, have the plate shell of reflection hole (or location hole) to form.Reflection hole can be different shape (being generally circle or ellipse), thereby obtains the color pixel cell of respective shapes.Each color LED lattice module generally has 8 * 8=64 color pixel cell.Color pixel cell, or by a multicore single tube, or realize by the colour mixture technology of a plurality of single core single tubes.

Traditional colorful light-emitting diode is a kind of round tube, is encapsulated in by single or multiple color LED chips 1.1 to form in the circular encapsulation tube 1.2; Described circular encapsulation tube 1.2, promptly the cross section of this tube is circular.

1, the circular colorful light-emitting diode of multicore (being called for short the multicore round tube)

The multicore round tube generally is encapsulated in the circular encapsulation tube 1.2 by a plurality of color LED chips 1.1 and forms, as shown in Figure 1.This pipe is installed in promptly becomes 1 color pixel cell in the reflection hole.The color LED lattice module requires the solid colour of all color pixel cells, and this is for the multicore round tube, because beam split color separation complexity, difficulty, packaging technology is had relatively high expectations, so the light intensity of this product, consistent wavelength are relatively poor, and qualification rate is lower, and cost is also high.

2, the circular colorful light-emitting diode (being called for short single core round tube) of single core

Single core round tube is encapsulated in the circular encapsulation tube 1.2 by 1 color LED chip 1.1 and forms, and is made up of a red LED chips and a circular encapsulation tube as a red light emitting diodes.Its color pixel cell generally is made up of 2,3,4 in reflection hole 2 and the hole thereof single core round tubes, as shown in Figure 2.Reflection hole 2 or be circular hole, or be elliptical aperture.Obviously, this color pixel cell has following shortcoming: because colorful light-emitting diode 1 is round tubular, a plurality of round tubes can only tangently make up in circular hole or elliptical aperture, must leave a plurality of cavities.Therefore, the colour mixture effect of its light is bad; The shape of luminous point is not attractive in appearance yet.For outdoor demonstration, its ill effect is because sighting distance is far away and out in the cold.But for indoor demonstration, because sighting distance is nearer, its ill effect is then very obvious.And at present, the use of indoor demonstration more and more widely.

Summary of the invention

1. the cross section of encapsulation tube 1.2 be 180 ° fan-shaped, 2 colorful light-emitting diodes 1 are combined into a complete circle; The circular combining structure of 2 pipes shown in Fig. 3 .1, Fig. 4 .1.

2. the cross section of encapsulation tube 1.2 be 120 ° fan-shaped, 3 colorful light-emitting diodes 1 are combined into a complete circle; The circular combining structure of 3 pipes shown in Fig. 3 .2, Fig. 4 .2.

3. the cross section of encapsulation tube 1.2 be 90 ° fan-shaped, 4 colorful light-emitting diodes 1 are combined into a complete circle; The circular combining structure of 4 pipes shown in Fig. 3 .3, Fig. 4 .3.

4. the cross section of encapsulation tube 1.2 be 180 ° fan-shaped, 2 colorful light-emitting diodes 1 are combined into a complete ellipse; The oval combining structure of 2 pipes shown in Fig. 3 .4, Fig. 4 .4.

5. the cross section of encapsulation tube 1.2 be 120 ° fan-shaped, 3 colorful light-emitting diodes 1 are combined into a complete ellipse; The oval combining structure of 3 pipes shown in Fig. 3 .5, Fig. 4 .5.

6. the cross section of encapsulation tube 1.2 be 90 ° fan-shaped, 4 pipes are combined into a complete ellipse; The oval combining structure of 4 pipes shown in Fig. 3 .6, Fig. 4 .6.

The utlity model has following advantage and good effect:

1. because the utility model is the combination of a plurality of single tubes, and the beam split of single tube, color separation, encapsulation, screening are easy to, and light intensity, consistent wavelength are better, so cost is low.

2. because the utility model zero distance gathering that is a plurality of sector tubes in circular or oval-shaped reflection hole 2 or gap are very little, therefore, the colour mixture of its light is effective, the good looking appearance of luminous point.

3. no matter outdoor demonstration, still indoor demonstration is because therefore its good visual effect has wide application prospect.
