Description

A kind of easy-to-dismount LED backlight

Technical field

The utility model belongs to LED backlight technical field, and in particular to a kind of easy-to-dismount LED backlight.

Background technology

The development of backlight can trace back in World War II, be used as the backlight of aircraft instrument by the use of microminiature tengsten lamp at that time Source, this is the starting stage of backlight development, and by semicentennial development, nowadays backlight has become electronics and independently learned Section, and research and development focus is gradually formed, backlight is mainly made up of light source, light guide plate, optical film piece, plastic frame etc., the back of the body Light source has brightness high, long lifespan, lights the features such as uniform, mainly there is tri- kinds of type of backlight of EL, CCFL and LED at present, according to Distribution of light sources position difference is then divided into side-light type and straight-down negative, as LCD modules constantly develop to brighter, lighter, thinner direction, Side-light type CCFL formulas backlight turns into the main flow of current backlight development, electroluminescent（EL）The thin amount of backlight body is light, there is provided Uniform light is consistent, and its power consumption is very low, it is desirable to operating voltage be 80~100Vac, there is provided the inverter of operating voltage can be 5/12/24Vdc Input transformation exports for exchange, but the service life of EL backlights is limited（Being averaged under 50% brightness conditions Service life is 3000~5000 hours, and service life will shorten dramatically in higher luminance level）, therefore, preferable EL Back lighting inverter allows output voltage and frequency to increase with the aging of EL bulbs, so as to extend the back side using EL The Acceptable life of the display of lighting source.

But existing LED backlight still has some irrational factors, the existing LED back ofs the body during use When in use, it is not special convenient that it is removed to light source, and with much time using, some small damages occur for unavoidable meeting Bad, some inconveniences can be brought to maintenance by removing trouble.

Utility model content

The purpose of this utility model is to provide a kind of easy-to-dismount LED backlight, to solve in above-mentioned background technology When in use, it is not special convenient that it is removed to the existing LED backlight proposed, with much time using, unavoidably Meeting some small damages occur, remove the problem of trouble can bring some inconveniences to maintenance.

To achieve the above object, the utility model provides following technical scheme：A kind of easy-to-dismount LED backlight, bag Light guide plate is included, diffuser plate is provided with above the light guide plate, and reflectance coating is provided with below light guide plate, the light guide plate Edge is provided with chute mount, and the bottom of the chute mount is provided with chute mount fixing threaded hole, and chute mount is interior Slip card and groove are provided with wall, the side of the light guide plate is internally provided with LED light-emitting sections and spacing fixed block, described spacing Fixed block is arranged on the outside of LED light-emitting sections.

Preferably, the LED light-emitting sections pass through spacing fixed block card and fixation with light guide plate.

Preferably, the light guide plate is slided and fixed by sliding card and groove with chute mount.

Preferably, the light guide plate is rectangular parallelepiped structure.

Preferably, the chute mount fixing threaded hole is provided with four altogether, and four chute mount fixing threaded holes are pacified respectively Four corners mounted in chute mount bottom.

Preferably, the light guide plate is bonded by double-sided tape with reflectance coating and connected.

Compared with prior art, the beneficial effects of the utility model are：The utility model is scientific and reasonable for structure, safe to use It is convenient, after the utility model is provided with side wrapped plate and mounting seat as the chute mount of integral type, when installing LED backlight, Only need to first pass through bolt installation chute mount, LED backlight is then arranged on by being fixedly connected for chute by chute mount On, when need dismantle LED backlight when, it is only necessary to LED backlight is extracted from the chute in chute mount, using It is next very convenient, simply；Set in the utility model in the junction of LED light-emitting sections and light guide plate limited location fixed block it Afterwards, after light-emitting section is installed into light guide plate, spacing fixed block serves well fixed effect, during dismounting, directly extraction , it is on the one hand simple to operate, on the other hand become more to consolidate.
