Description
Technical field
The utility model relates to a kind of backlight modules, especially controllable type multiple light courcess back light module unit structure.
Background technique
Existing down straight aphototropism mode set structure is to design whole face LED light (quantity about 3000-10000 in the bottom BLM
), then go the light-dark ratio example of control LED light to need using such structure more than 100 groups by the design of circuit design circuit
Circuit loop removes the bright dark of control LED light, and IC model need to be selected especially, and need to design more IC, meanwhile, LED light quantity is excessive,
It is higher in the upper bad ratio of LED light welding, cause backlight module cost excessively high, does not meet the market demand.
Summary of the invention
In order to solve deficiency in the prior art, the purpose of this utility model is to provide a kind of controllable type multiple light courcess backlights
Modular structure.
To achieve the above object, the utility model uses following technical scheme:
Controllable type multiple light courcess back light module unit structure comprising glue frame, LED module, and the optics being covered on LED module
Membrane material, the optical film material include the diffusion sheet set gradually from the inside to the outside, lower brightening piece and upper brightening piece, the LED module
It is made of multiple independent light emitting regions, each light emitting region includes multiple LED light and the circuit time for controlling the LED light
Road is separated by shelves wall between adjacent light emitting region.
Further, filling has the guide-lighting characteristic glue with change light source colour between the LED module and optical diaphragm
Water.
Further, the LED module is spliced to form by multiple single light emitting modules.
The utility model uses above technical scheme, the backlight module of multiple light emitting regions is arranged, according to each luminous zone
LED light light emitting angle in domain defines LED light quantity required in single light emitting region, reduces LED light, circuit loop and IC
Quantity, and LED module can by circuit loop carry out brightness control, the visual effect of backlight module, LED mould can also be improved
Block is designed with shelves wall, is promoted backlight module brightness, is effectively promoted the utilization rate of light, the utility model can reduce backlight module
Cost, to accord with the demands of the market.
