As preferred technical scheme, described plastic shell is provided with reflection cavity, described reflection cavity is arranged in rows on plastic shell, and described reflection cavity top is funnel or trapezoidal shape, and its effect makes its more effective gathering light of sending of LED and by funnel or trapezoidal shape, light reflected away.The glue of mixing yellow fluorescent powder is filled in described reflection cavity bottom box.The glue of mixing yellow fluorescent powder is mix after yellow fluorescent powder and special glue carry out proportioning in the ratio specified, use special spot gluing equipment, evenly accurately the glue spots being mixed with yellow fluorescent powder is had in the bottom box of LED digital screen reflection cavity of blue-ray LED in nation surely by the glue amount of regulation, glue forms the colloid of a regular square around LED, is wrapped up closely by LED after solidification.And glue can help LED light line effectively to spread and increase certain brightness, and wrapped up completely by LED and fix, protection LED is not damaged.By reflection cavity, LED light line is reflected from bottom box, the content that the position making the shape of surperficial accent position or be affixed on surperficial its corresponding accent of diaphragm has word, pattern maybe will show is easier to be embodied.
As preferred technical scheme, described blue-ray LED is arranged in rows on pcb board, and described blue-ray LED both positive and negative polarity is connected on the golden road solder joint of pcb board, makes its positive-negative polarity conducting.By insulating gel, blue-ray LED is affixed on the pad of pcb board, then the pad that the electrode on blue led is corresponding with its polarity is connected by bonding equipment with metal welding wire, pad by the connection on PCB to corresponding pin to obtain the voltage for blue-ray LED.
As preferred technical scheme, described pcb board is provided with pilot hole, described plastic shell is provided with reference column, and described plastic shell is fixed on by reference column on the pilot hole on pcb board, makes each blue-ray LED be placed in the center of the reflection cavity bottom box of plastic shell.And its physical dimension size of bottom box of blue-ray LED placed by each reflection cavity of plastic shell and be highly consistent, consistent to ensure charging capacity, evenly luminous.
As preferred technical scheme, described diffusion barrier is divided into viewing area and not viewing area, described not viewing area silk-screen black ink.This diaphragm adopts has diffusivity and the high material of transmittance, bottom is first silk-screen black ink in not viewing area, the glue that silk-screen one deck adhesion is strong again, is affixed on LED digital screen surface, can make the content that will show and clear patterns and show uniformly when white light transmission display region.A pattern on the corresponding diffusion barrier of each plastic shell reflection cavity (this pattern can be designed to different shapes or word as required, and this zone material has diffusivity, white light make through this region the content that will show is clear to be shown uniformly).
During use, this LED digital screen supplies suitable voltage by driving circuit or external power supply, makes blue-ray LED send blue light, and blue light through the glue being mixed with yellow fluorescent powder in LED digital screen reflection cavity bottom box, thus inspires uniform white light.
The beneficial effect of the White light LED digital display screen of the utility model a kind of some glue mode is:
Relative to the LED digital display screen of conventional white light SMD lamp, greatly reduce cost, the illumination effect of white light SMD lamp can be reached again simultaneously.
Relative to the LED digital display screen of conventional white light SMD lamp, its product structure can do less.The product that more mounting structure requirements are compact can be applied to.
The white light LEDs digital screen carrying out embedding in glue is mixed into relative to existing fluorescent powder, the consumption of what this patent was a large amount of save fluorescent powder and glue, greatly reduces production cost, simultaneously owing to decreasing glue quantity, its product weight also mitigates, thus saves transportation cost.
