Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
At present, the backlight source system with the lateral-entering type structure of the LED light source is widely applied to the industry of lighting lamps and the industry of LCD panels. The side-in type structure LED package is characterized in that a lamp strip enters light from the side edge of the light guide plate and emits light from the plane on the upper part of the light guide plate. The LED lamp strip is connected with the frame back plate through the lamp body heat conducting glue to play a role in heat dissipation, but the heat dissipation area of the frame and the back plate is limited, the heat transfer distance is long, the overall heat dissipation level is limited, high-power illumination and high-brightness display cannot be achieved, and generally only about 300W/m can be achieved2。
For this purpose, fig. 1-5 show a side-in type light-emitting flat lamp provided by an embodiment of the present invention, which includes a frame back plate 1, an annular frame 2, and a light guide plate assembly 3 surrounded and fixed by the annular frame 2, a side-in type LED light bar 4 and a water cooling tube 5 are disposed on the annular frame 2, and a light-emitting direction of the LED light bar 4 faces to a center of the light guide plate assembly; the LED lamp strip 4 is connected with the water-cooling tube 5 through heat-conducting glue.
A water-cooling heat-radiating tube bank 6 is arranged at a position, close to the annular frame, outside the back plate, a water outlet of the water-cooling tube is communicated with a water inlet of the water-cooling heat-radiating tube bank, a water outlet of the water-cooling heat-radiating tube bank is communicated with a water inlet of a water pump 7, and a water outlet of the water pump is communicated with a water inlet of the water-cooling tube.
In view of the above, it should be noted that the side-entry light-emitting flat lamp has a generally square structure. Frame backplate and annular frame formula structure as an organic whole usually, this annular frame be groove structure, can fix the light guide plate, also can set up side income formula LED lamp strip wherein, simultaneously, still set up the water-cooling tube behind one's back at LED lamp strip. The water cooling pipes on all sides are communicated together to form a closed loop structure. The LED lamp strips on all sides are also communicated together to form a closed-loop structure. The control unit is matched with the corresponding control unit and controls the opening, closing and brightness of the LED lamp strip. Wherein, the water-cooling pipe is preferably made of pure copper materials, and is secondly made of aluminum materials.
