Description
The utility model relates to a kind of display screen projection light generation device, particularly computer display projection light generation device.
Because the requirement of speed and degree of accuracy, the use of computing machine is to the utmost to be general.And the demonstration of conventional computer display screen, no matter numeral or symbol all show with black or the blue monochromatic of Cheng Fanbai, because too dull novel variability is not good, causing the people changes over the liquid crystal (LCD) of computer display conduction slide and is inverted, make and to produce when using that numeric character becomes transparence and background is the demonstration of black, and behind the conduction slide, cover a light shield 4, be matched with light shield 4 bottoms and install the projection light generation device (as shown in Figure 1) that substrate 2 constitutes with diffusion sheet 3.Be installed on the high briliancy light emitting diode 5 that is communicated to circuit on this substrate 2, when power-on is used, high briliancy light emitting diode 5 is via the reflection and diffusion sheet 3 diffusions of light shield 4, and can produce uniform illuminating effect, after seeing through the conduction slide, numeric character is generated and the identical color of high briliancy light emitting diode 5 emission light, thereby non-black or the blueness of only limiting to of the Show Color that can impel computer display, cause the display effect that can be made into each color, choose for the user.Right because the high light restriction of high briliancy light emitting diode 5, high briliancy light emitting diode 5 must be apart from the suitable distance of conduction slide, and be able to light shield 4 optically focused in addition, to prevent the to cause conduction slide that halation phenomenon is arranged, be to limit owing to this projection light generation device must have certain distance first, to cause the volume that can cause computing machine and can't reduce more greatly; Moreover high briliancy light emitting diode 5 is spot positions of installing in light shield 4 bottoms, and light shield 4 is into specific reflection radian, thereby the conduction slide of different size dimensions is not all can be suitable for, only can be with the light shield 4 of multiple, cooperate the conduction slide of relative size to use, and if settle the high briliancy light emitting diode 5 of different color and lusters simultaneously in light shield 4 bottom spot positions, because of each high briliancy light emitting diode 5 position has different slightly with the reflection angle of light shield 4, and easily cause the optically focused uneven phenomenon, be can't settle the high briliancy light emitting diode 5 of different color and lusters, the demonstration of conversion different colours for you to choose simultaneously in light shield 4 bottoms; Three make the high briliancy light emitting diode 5 that cooperates different colours, and produce multidisplay effect because the reflection angle restriction of light shield 4 specific optically focused is difficult for making separating of multizone, so be to have to add the improved necessity of research again.
Fundamental purpose of the present utility model in that a kind of improved computer display projection light generation device is provided, need not to reflect light shield, and can effectively reduce the thickness of projection light generation device, and then reduced the volume of computing machine.
Secondary objective of the present utility model is providing a kind of improved computer display projection light generation device, can produce the multicolor displaying effect of respective color.
A purpose more of the present utility model, a kind of improved computer display projection light generation device is being provided, can automatic or manual or be transformed into the different color LEDs irradiation or, show effectiveness and produce the different colours conversion with different brightness and color LEDs mixed exposure simultaneously.
Another purpose of the present utility model is providing a kind of improved computer display projection light generation device, can make elasticity effectively adapt to variant conduction slide and use.
Above-mentioned purpose of the present utility model realizes by following technical proposals.
A kind of improved computer display projection light generation device, be by the liquid crystal display conduction slide that is inverted, light emitting diode, diffuser plate and substrate are formed, it is characterized in that: the bottom becomes the through hole shape and the prolate shape leaded light seat of the little one-tenth flare of inner circumference, and embedding is covered the substrate in combination that hides worn-out leaded light seat bottom through-hole and is formed, wherein the inner face of substrate is installed on the respective color light emitting diode of equidistant arrangement, light emitting diode is to be connected with large scale integrated circuit with control through the circuit of substrate, and the inner bottom part of assembly is still filled fixing with the leaded light fixing glue, and diffuser plate at leaded light seat top coated with the sheen effect, and compress the liquid crystal display conduction slide that is inverted with diffuser plate, make the display screen place of being fixed in the computer housing seat.
Except that above-mentioned essential features, also can replenish following technology contents in the implementation process:
Be separated into several different zones with partition wall in this leaded light seat, and cooperate each zone, be installed on the respective color light emitting diode of equidistant arrangement in the relative position place in the substrate inner face;
Installed with the sortord that multi-color LED is settled simultaneously, and the control of cooperation large scale integrated circuit.
Advantage of the present utility model is:
Need not to reflect light shield, thereby can effectively reduce the thickness of projection light generation device, and then reduced the volume of computing machine; The light emitting diode of zones of different different colours passes this regional numeric character through the diffusion sheet projection when using by unlatching, and can produce the monochrome or the multicolor displaying effect of respective color, in addition can also automatic or manual modulation mode conversion become the effect of the demonstration of different colours; And the tool integral thickness is small and exquisite, is easy to the elasticity adjustment and cooperates making to adapt to variant conduction slide use.
