Problems solved by technology

[0006] However, due to the undesigned arrangement of the LED chips, the light-emitting range of each LED chip overlaps too much, making it difficult to improve the utilization rate of light.
When the components driving the LED chip (such as the circuit board) are damaged, the housing needs to be disassembled to take it out, making maintenance difficult
Similarly, when the components driving the LED chip are damaged, the brightness of the entire flat panel light may be greatly reduced (or even extinguished), making it difficult to use
In addition, when the LED chip emits light, because the LED chip is a point light source with high directivity, in order to meet the requirements of aesthetics and light uniformity, the diffuser plate cannot use a high-transparency type, which indirectly affects the light utilization rate

Abstract

The invention discloses a panel light. The panel light comprises a shell and multiple light bar modules located in the shell. Each light bar module comprises a circuit board and multiple light sources located on the circuit board and electrically connected to the circuit board. In addition, connecting lines of the light sources of the light bar modules form a polygonal honeycomb array, so that the overall light-emitting range of the light sources is widened.

Description

technical field [0001] The invention relates to a flat lamp. Background technique [0002] In daily life, lighting equipment is an indispensable and important tool. Most of the existing lighting equipment uses traditional light bulbs or lamp tubes as light sources. Among these lamps or bulbs, fluorescent tubes, tungsten filament bulbs and halogen bulbs are more common. Since traditional tungsten filament bulbs consume a large amount of electric energy, lighting devices using light-emitting diodes (Light-Emitting Diodes; LEDs) as light sources have become more and more popular in recent years. Compared with tungsten filament bulbs, LED light sources have the advantages of long life, low power consumption, shock resistance, and high brightness. [0003] The flat panel light is a kind of lighting equipment, which can use LED as the light source. In a known LED flat panel light, an LED light bar is arranged on the side surface inside the casing, and a reflector is placed on ...
