Description
Technical field
The utility model is related to back lighting device technical field, specially a kind of LED backlight of high saturation color coloured silk.
Background technology
Liquid crystal display be it is current in, the mainstream of small area display screen, but liquid crystal is a kind of passive type display screen, own
It will not shine, need the illumination for relying on the external world that could show writings and image, the source that present ambient light is shone is mainly by screen
The CCFL fluorescent tubes of surrounding introduce light from side, and using even ray machine structure, by liquid crystal display, there are one the illumination of brightness uniformity.
The progress of LED causes many liquid crystal display factories household LED to substitute CCFL in recent years, and the form of irradiation is copied
CCFL fluorescent tubes also have and LED lighting board are loaded onto at the back side of liquid crystal display as outer irradiation source, be referred to as in the industry from side entering light
LED backlight, no matter which kind of form of irradiation LED it is substantially following two.
A：General white light LEDs
This white light LEDs are to be made of the LED chip of blue light-emitting plus yellow fluorescent powder, in its spectrum feux rouges into
Split pole is few, so after making liquid crystal display, its color saturation is only 72~75%, and color is not ideal enough.
B：The white light LEDs of RGB
Three kinds of colors of red, green, blue press 3：6：After 1 ratio mixes, white light can be also formed, makees liquid crystal display with this LED
It after backlight, shows that the ability of color just becomes stronger, 85% or so can be reached, but since LED luminescence chips are semiconductors
Device, what is sent out is monochromatic light, and shared spectrum is very narrow, so the color of display is still unsatisfactory.
In order to improve the prior art, people have carried out long-term exploration, it is proposed that miscellaneous solution.For example,
Chinese utility model patent application No. is 201120003081.2 discloses a kind of liquid crystal display with high color saturation
The LED backlight of device, the backlight are sent out in 450~680nm wavelength periods by the chip portfolio of at least five kinds of different emission wavelengths
Light forms the continuous spectrum of class daylight, improves color saturation；Each chipset is powered by individual constant-current drive circuit,
Once current regulation determines, it can keep constant.The light intensity that it is exported can be changed in the electric current for adjusting each chip, so as to change
The correlated colour temperature of light is sent out, convenient for adjusting contrast, brightness and color saturation.
But it is had the following disadvantages in the utility model：
(1) liquid crystal display needs just be installed to product after stringent detection confirms qualification in installation process is produced
On, offer backlight is needed to be detected to the performance of liquid crystal display, but the backlight of fixed position in liquid crystal display detection process
It is inflexible for use in detection process, therefore cause detection process slower；
(2) in order to ensure optical brightness requirement, LED is relatively concentrated in the layout of short side, can be made when LED is lighted
Heat into short side increases rapidly, and LED temperature can be made to exceed the range used, and LED luminance is caused to reduce and is shortened with service life,
The problems such as raising of backlight source temperature can also cause backlight component bad, such as guide-lighting slab warping, optical film material fold；
(3) at work, electricity device can be by the adsorbing powder dust in air under electrostatic interaction for electricity device so that itself
It is dirty, while the dust covered can make the heat dissipation effect on electricity device be deteriorated, and influence its service life.Some existing heat dissipations
Device due to being the radiator of wind-cooling heat dissipating, reaches radiating and cooling by way of gas stream passband is accelerated to walk heat
Effect, due to inevitably carrying dust dust in air-flow so that electricity device with the dust of absorption than not
Set air cooling equipment when absorb it is more, can make in this way air cooling equipment heat dissipation effect be deteriorated even failure.
