Problems solved by technology

At present, most of the LED panel lights on the market are direct-type panel lights. The direct-type panel lights include bottom reflectors, LED strips arranged in parallel arrays, diffusion plates and wide frames. The panel lights with this structure are large in size and thick. If To meet the large size, high brightness and uniform picture, more LED arrays and high transmittance and high haze diffuser plates are required. If the diffuser plate has poor haze, you will see a light on the light emitting surface of the flat panel lamp Individual LED light shadows seriously affect the lighting effect

Embodiment 1

[0018] as attached figure 1 , attached figure 2 , attached image 3 As shown, the LED flat panel lamp of this embodiment includes a lampshade shell 1 and a light-emitting surface 2. An LED light bar 3 is provided on the inner edge of the frame around the lampshade shell 1, and a power connection device 4 is provided on the back of the lampshade shell 1. The lampshade shell 1 1. A photosensitive switch 5 for controlling the opening and closing of the LED light is provided on one side of the frame. A light guide plate 6 is also arranged inside the lampshade shell 1. Light guide points 7 are distributed on the front of the light guide plate 6. The light guide plates on the light guide plate The light guide dots 7 are printed by ink screen printing, and the light guide dots 7 are evenly distributed on the front of the light guide plate 6 by silk screen printing.

[0019] In this embodiment, a light guide plate 6 is added, which can effectively reduce the number of LED light ba...

Abstract

The invention relates to the field of LED lamps, in particular to an LED panel lamp. The LED panel lamp comprises a lampshade shell and a light outgoing face. LED lamp bars are arranged on the inner edge of a frame of the shell, a power supply connecting device is arranged on the back face of the shell, a light guide plate is further arranged in the lampshade shell, light guide net points are distributed on the front face of the light guide plate, and the light guide net points on the light guide plate are printed in an ink screen-printing mode and are screen-printed on the front face of the light guide plate in an evenly distributed mode. Because the light guide plate is added to the LED panel lamp, the number of the LED lamp bars can be effectively reduced, light of a light source is evenly reflected onto the light outgoing face through the light guide net points on the light guide plate, the light reflection effect is good, and the illuminating effect of the LED panel lamp can be improved easily. The LED lamp bars are arranged on the inner edge of the frame on the periphery of the lampshade shell, and the size and the thickness can be effectively reduced compared with LED array arrangement of a direct-lighting panel lamp.

Description

technical field [0001] The invention relates to the field of LED lamps, in particular to an LED flat panel lamp. Background technique [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, most of the LED panel lights on the market are direct-type panel lights. The direct-type panel lights include bottom reflectors, LED strips arranged in parallel arrays, diffusion plates and wide frames. The panel lights with this structure are bulky and thick. If To meet the large size, high brightness and uniform picture, more LED arrays and high transmittance and high haze diffuser plates are required. If the diffuser plate has poor haze, you will see an A single LED light shadow seriously affects the lighting effect. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, an...
