CN201827736U - LED back light source - Google Patents

Abstract

The utility model discloses an LED back light source comprising a high power LED extended light source, a light guide plate, and a frame. The high power LED extended light source is fixed in the frame, and is embedded in the light guide plate. The high power LED extended light source comprises a plurality of small LED light sources. By using the high power LED extended light source, the heat dissipation problem can be effectively solved, and the utilization rate of the electric energy can be improved.

Description

A kind of LED-backlit source

[technical field]

The utility model relates to a kind of electric light source, relates in particular to a kind of LED-backlit source.

[background technology]

At present, backlight has been widely used in the outdoor advertising marking field, wherein the LED-backlit source makes the people parent look at most, because its have the life-span long, efficient is high, advantage such as low in energy consumption, but in the prior art, the LED-backlit source requires high for heat radiation, can only use in small size, low power backlight, the defective value of described prior art must improve.

[utility model content]

The purpose of this utility model is at above-mentioned technological deficiency, and a kind of LED-backlit source is provided, and this a kind of LED-backlit source can be applied in large scale, the powerful backlight.

The technical solution of the utility model is as described below: comprise high power LED expansion light source, LGP, framework, high power LED expansion light source is fixed in the framework, it is characterized in that, the high power LED expansion light source that is fixed on the framework is embedded in the LGP, and described high power LED expansion light source comprises the led light source that several are little.

According to the utility model of said structure, its beneficial effect is that the utility model adopts high power LED expansion light source, has effectively solved its heat dissipation problem, has improved the utilization rate of electric energy.
