Problems solved by technology

[0003] The existing LED flat panel lights are mainly composed of light strips, light guide plates, diffusion plates, reflectors, and light frames. Due to the use of traditional structural methods (that is, the diffusion plates, light guide plates, reflectors, and back plates are stacked in sequence), In actual production, the product is affected by labor and parts gaps, and problems such as bright edges, water lines, and partial shadows are prone to appear during the installation process, making assembly more difficult and easily causing secondary repairs, resulting in a huge waste of labor costs
Moreover, the assembly is difficult and the efficiency is relatively low

Embodiment 1

[0025] Embodiment 1: A kind of side-light type surface light source LED lamp, such as figure 1 and figure 2 As shown, the LED lamp includes a lamp frame 1, a lamp bar 2 and a pre-installed module 3;

[0026] The pre-installed module 3 includes a back plate 31 and an optical assembly 32. The optical assembly 32 includes a diffusion layer 321, a light guide layer 322 and a reflective layer 323 arranged in sequence. The optical assembly 32 has a light exit surface, a back surface and an entrance surface. The light side, the light exit surface is opposite to the back surface, the light entrance side is located between the light exit surface and the back surface, the light exit surface is the outer surface of the diffusion layer, and the back plate is located on the optical assembly The back side of the optical component is fixed to the optical component and the back plate through the connection part 311 extending from the edge of the back plate to the optical component to form t...

Embodiment 2

[0034] Embodiment 2: A side-illuminated surface light source LED lamp, the structure of which is similar to that of Embodiment 1, except that the optical assembly and the back plate are fixed together by connectors to form the pre-installed module.

[0035] The connecting part is an adhesive tape, and the adhesive tape extends along the side of the optical assembly along the back of the backplane and extends to the light-emitting surface to wrap the optical assembly.

[0036] In this embodiment, the light incident side is two opposite sides of the optical component, and the side opposite to the light incident side is defined as the non-light incident side, and the connecting member is located on the non-light incident side of the optical component. side, but not limited thereto, the light-incoming side may also be a side of the optical component.

[0037] The connecting piece is transparent, and the connecting piece is located on a side of the optical component, and the side i...

Abstract

The invention discloses a lateral light incidence area light source LED lamp which comprises a lamp frame, a lamp strip and a preassembled module, wherein the preassembled module comprises a back plate and an optical assembly; the optical assembly comprises a diffusion layer, a light guide layer and a reflection layer in sequential arrangement; the optical assembly is provided with a light emergence surface, a back surface and a light incidence side surface; the light incidence side surface is positioned between the light emergence surface and the back surface; the light emergence surface is the outer surface of the diffusion layer; the back plate is positioned at the back side of the optical assembly; the optical assembly and the back plate are fixed together to form the preassembled module through a connecting element or a connecting part formed by extending from the edge of the back plate to the optical assembly; and the preassembled module is arranged at the lamp frame so that thepreassembled module is fixed to the lamp frame in the edge position, and the lamp strip is positioned in the position of the light incidence side surface of the optical assembly. The optical assemblyand the back plate are fixed together to form the preassembled module through the element or the connecting part formed extending from the edge of the back plate to the optical assembly, and then, thepreassembled module is assembled into the lamp frame with the lamp strip; and a modular assembly mode is used, so that the assembly efficiency and the assembly precision are improved.

Description

technical field [0001] The invention belongs to the field of equidistance technology, and in particular relates to an LED lamp. Background technique [0002] LED panel lights use LED lamp beads to emit light through the light guide layer and then project the light through the light-transmitting diffusion plate. Because the light is soft and environmentally friendly, it is more and more popular and accepted by consumers, and the market is huge. [0003] The existing LED flat panel lights are mainly composed of light strips, light guide plates, diffusion plates, reflectors, and light frames. Due to the use of traditional structural methods (that is, the diffusion plates, light guide plates, reflectors, and back plates are stacked in sequence), In actual production, the product is affected by labor and part gaps, and problems such as bright edges, water marks, and partial shadows are prone to appear during the installation process, making assembly more difficult and easily caus...
