Description
Technical field
The present invention relates to a kind of backlight module and light source module thereof, particularly a kind of backlight module and light source module thereof that is used in the downward back photo structure.
Background technology
Because the user makes LCD replace traditional cathode-ray tube display, and becomes the main flow of current display for the requirement of display thin typeization.
In the required zero element cost proportion of LCD, be higher three of cost proportion with colored filter, drive IC and backlight module.Wherein the essential structure of backlight module mainly is made up of three parts, i.e. light source, light guide plate and optical thin film.
Backlight module develops according to the requirement of its scale and light source position and following three macrostructures: (1) side-light type (Side-Edge Backlight) backlight: generally be usually used in 14 o'clock following backlight modules, the light source design of its side incident has the characteristic of light weight, slim, narrow frameization, low consumption electric power, by general mobile computer is adopted.(2) Staight downward type backlight (Direct Type Backlight): in the backlight module of large-size, side-light type is backlight can't to take advantage in weight, consumption electric power and brightness, and the Staight downward type backlight that does not therefore contain light guide plate just is developed.Light source by baffle reflection after, upwards through diffuser plate evenly disperses after in the front ejaculation, its advantage is lightweight, high briliancy, good bright dipping visual angle, light utilization ratio height, simple structureization etc., is usually used in general display.Because direct-type backlight can be avoided side-light type side light leakage situation backlight, so whole luminous energy efficient is increased; And in the structure of direct-type backlight, need not see through light guide plate and can produce uniform light, so can reduce the production and the assembling of part.Take a broad view of according to present LCD TV under wide viewing angle, high brightness, high-contrast etc. require, direct-type backlight has its significant advantage with respect to side light type backlight.
Please refer to shown in Figure 1ly, with the direct type backlight module in the display, using the backlight module of led light source in the prior art is to be formed by many component-assembled, need utilize a large amount of screws to lock between each parts.Mainly comprise a framework (being pedestal) 11 in the existing backlight module, a plurality of strip light-emitting components 12 (being LED light bar) then are locked in respectively on framework 11 bottoms 111, need in addition the useful bracing frame 13 that sets up for the required optical thin film 14 of backlight module, and optical thin film 15 is set up in framework 11 upper limbs 112.In addition, the bottom surface 113 of framework 11 can be assembled with various cooling mechanism, so that the high heat that light-emitting component 12 produces is dispersed.
From the above, existing backlight module need utilize a large amount of screws to assemble, and has therefore caused each parts manufacturing cost height and the low phenomenon of packaging efficiency.Because in the manufacturing cost of backlight module, material cost occupies ninety percent nearly, so be difficult to effectively reduce its cost with regard to material items, only can on assembly expenses, be compressed, therefore, the improvement by structure and assembling process is industry target of generally pursuing and the important topic of endeavouring to reduce the backlight module manufacturing cost.
Summary of the invention
Because above-mentioned problem, order of the present invention provides a kind of light source module that can exempt loaded down with trivial details assembling.
Another object of the present invention provides a kind of backlight module that can reduce number of components and assembling procedure.
Therefore, for reaching above-mentioned purpose, comprise a light source and a pedestal according to light source module of the present invention, wherein light source comprises a substrate and is arranged at least one light-emitting component on the substrate, and a side of pedestal is formed with a slot with ccontaining base plate.
In order to reach above-mentioned purpose, comprise at least one light source module, one first optical element and one second optical element according to backlight module of the present invention.Wherein, the pedestal of light source module has a slot with the ccontaining light source that the substrate of at least one light-emitting component is set, and a fastening structure becomes one to fasten those light source modules, and optical component is arranged on the light source module.
From the above, because of have a pedestal that is formed with slot according to backlight module of the present invention and light source module thereof, therefore the substrate utilization at light source place can be slipped into or snaps on the slot that mode is arranged at this pedestal, and pedestal and slot are formed in one, so can exempt the operation loaded down with trivial details consuming time that need utilize a large amount of screws to lock and cause and reach the reduction assembly cost when assembling backlight module and light source module in the past.Further, because in backlight module of the present invention and the light source module thereof, pedestal more can be in conjunction with cooling mechanism when making except that having integrated slot.In addition, the both sides of pedestal more can have engaging support mechanism, make pedestal to carry out assembly unit for the different demands of size in response to the user, and the assembling that therefore can make whole backlight module is easy, efficient activity, customized more.
