Problems solved by technology

[0002] LED panel lights have been widely used in various industries due to their advantages of energy saving, high brightness, and no infrared and ultraviolet radiation. At present, there are two types of LED panel lights on the market; one is a direct type panel light, and the other is a side panel light. Built-in flat panel light; the structure of direct type flat panel light is: bottom reflector, LED array, diffuser plate and wide frame; if this structure is to meet large size, high brightness and uniform picture, more LED arrays and high transparency are required. If the diffuser plate has poor haze, you will see LED light shadows one by one on the light emitting surface of the panel light; this will seriously affect the lighting effect; the side-entry panel light is designed with a light guide plate , can effectively reduce the number of LED light strips, but due to the limitation of the arrangement of the LED light strips, there will be a significant difference in luminance between the light-incoming part and the light-emitting surface of the light guide plate; in addition, the above two flat panel lights are installed with external frame structure, thereby causing its light-emitting area to decrease, volume to increase, and thickness to increase; therefore, the present invention urgently needs to provide a new high-brightness LED flat panel light

Abstract

The invention relates to a high-brightness light-emitting diode (LED) panel lamp, in particular to a frameless high-brightness LED panel lamp. The panel lamp comprises a light guide plate, wherein a trough is formed on the light guide plate; an LED lamp strip is arranged in the trough; and a reflective sheet is arranged at the lower end of the light guide plate. Through the design that the LED lamp strip is arranged in the trough, an external frame is not needed, and the LED lamp strip is directly arranged in the light guide plate, so that frameless display of the panel lamp is realized, and the light-emitting area of the panel lamp is maximized; and meanwhile, the size and the thickness of the panel lamp are effectively reduced, the manufacturing cost is saved, and the production efficiency is improved.
