Description

Technical field: [0001] The invention relates to the technical field of LED products, in particular to a multi-pole omnidirectional LED light source and a bracket thereof. Background technique: [0002] As we all know, traditional incandescent lamps have high energy consumption and very low energy utilization rate. Only less than one tenth of the energy is converted into light energy, and the rest is wasted as heat energy. So people have been trying to find ways to replace incandescent lamps with new light sources. Therefore, energy-saving lamps came into being. Because it is cheaper and easier to manufacture than incandescent lamps, it has been widely used and has a tendency to gradually replace incandescent lamps. Energy-saving lamps use the principle of electronic excitation to emit light. Compared with incandescent lamps, energy-saving lamps have the advantage of saving electricity. But one disadvantage of energy-saving lamps is that energy-saving lamps contain mercur...

Problems solved by technology

However, LED lights also have certain defects: due to the strong directionality of the light emitted by the LED chip, its illuminated area is limited, unlike incandescent lamps and energy-saving lamps where the light source is divergent.

The disadvantages of this method are obvious: the cost is high, and the assembly process is complicated due to the need to install multiple LEDs on the lamp head

It can be seen that this solution is only to treat the symptoms but not the root cause, and does not solve the problem of LED lighting in all directions from the source.

[0010] In addition, the multiple LEDs installed in the light-emitting lamp head of the lamp are all connected in series. When they are working, they are all lit or extinguished at the same time. LEDs of different colors are more difficult to adjust the light, causing greater trouble to users

Although there are some LEDs installed on the PCB board to controllably adjust the light emission, they can only achieve planar light emission and cannot achieve the purpose of omnidirectional light emission.
