Description

There is the LED diode point array module of colour mixture lens in the locating hole front

Technical field

The utility model relates to a kind of LED diode point array module, specifically, relates to the LED diode point array module that there are the colour mixture lens in a kind of locating hole front.

Background technology

Along with improving constantly of the fast development of LED diode (semiconductor light-emitting-diode) technology and people's living standard, esthetic sentiment, a kind of full-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.

Traditional full-color LED display screen is spliced by several LED lattice modules (or cell board or casing).Each LED lattice module again by LED diode, circuit board, have the plate shell of locating hole (or reflection hole) to form, locating hole is generally 8 * 8=64, also have 16 * 8=128 and 32 * 16=512 etc., it laterally, vertically dot spacing is all consistent, locating hole can be different shape, thereby obtains the luminous point of respective shapes.

As shown in Figure 1, 2, 3, for traditional by a plurality of LED diodes (1), circuit board (2), the LED lattice module that has the plate shell (3) of locating hole (4) to form, the locating hole (4) of its plate shell (3) is that pierce in the front, and its effect just plays the role of positioning to a plurality of LED diodes (1).Because pierce in its front, although LED diode (1) colour mixture of a plurality of different colours becomes a kind of required color, but the colour mixture effect is bad, be reflected in people visually, it or not the luminous point of a mixing, but a kind of set of a plurality of exposed luminous points, light sensation is not soft yet, and is especially indoor and show that closely its colour mixture effect is poorer.

Summary of the invention

The purpose of this utility model overcomes the shortcoming and defect of the LED diode point array module existence of piercing in above-mentioned locating hole (4) front exactly, provides the better locating hole of a kind of performance (4) front that the LED diode point array module of colour mixture lens is arranged.

The purpose of this utility model is achieved in that

By Fig. 4-9 as can be known, LED diode point array module by LED diode (1), circuit board (2), have the plate shell (3) of locating hole (4), colour mixture lens (5) to form; The two poles of the earth of LED diode (1) are welded on respectively on the corresponding solder joint of circuit board (2), and circuit board (2) is sleeved on the plate shell (3), in the front of locating hole (4) colour mixture lens (5) is arranged.

LED diode (1) colour mixture of different colours becomes a kind of required color, owing to pass through the transmission and the scattering of colour mixture lens (5) at last again, is reflected in people visually, is the luminous point of a mixing, and light sensation is extremely soft; Enlarged simultaneously the visual angle in the horizon range again.

The utlity model has following advantage and good effect:

1) simple in structure, implement easily.

2) display effect is good.

In a word, because therefore the utility model ratio of performance to price height has wide application prospect.

The specific embodiment

1, colour mixture lens (5)

In the front of locating hole (4) colour mixture lens (5) are arranged, colour mixture lens (5) or be epoxy resin, or for being added with the epoxy resin of scattering diluent.

The manufacture craft of colour mixture lens (5) is as follows:

High temperature gummed tape is sticked in front at the plate shell (3) of module, and the front of locating hole (4) is sealed fully; Then, plate shell (3) inversion is kept flat, promptly each locating hole (4) quantitative perfusion epoxy resin solution is given by encapsulating equipment up in the bottom surface of locating hole (4), plate shell (3) is lain in vacuumize processing in the vacuum tank again; Then, do admittedly, make the front of the locating hole (4) of plate shell (3) form a kind of colour mixture lens (5) through high-temperature shaping.When plate shell (3) front was the plane, then colour mixture lens (5) front was a level crossing; When plate shell (3) front was cambered surface, then colour mixture lens (5) front was a globoidal mirror.

2, plate shell (3)

The shape that plate shell (3) is positive or be the plane, or be cambered surface.

3, LED diode (1)

LED diode (1) or for pin LED diode is arranged, or be the adopting surface mounted LED diode, or be led chip, or be the led circuit plate.

4,1-8 LED diode (1) is set in locating hole (4).
