Anti-dazzling ultraviolet LED lighting device

Abstract

The invention relates to the technical field of LED lighting, and discloses an anti-dazzling ultraviolet LED lighting device. The anti-dazzling ultraviolet LED lighting device comprises a lampshade and a base body unit fixed at the opening end of the lampshade. An LED luminous module is arranged above the base body unit. The LED luminous module comprises a base plate fixed above the base body unitand a LED wafer fixed above the base plate. A transparent light distribution unit is arranged in the direction of the light output of the LED wafer. The transparent light distribution unit comprisesa solid first light transmission part and a hollow second light transmission part. The first light transmission part is fixed above the LED wafer, and the second light transmission part is fixed on the first light transmission part. The diameter, in the horizontal direction of the second light transmission part, of the outer side surface of the second light transmission part decreases in sequencein the direction of being from the bottom end to the top end, and the diameter, in the horizontal direction the second light transmission part, of the inner side surface of the second transparent partincreases in sequence. According to the anti-dazzling ultraviolet LED lighting device, an emergent ray is refracted and scattered by the lighting device to achieve the effect of light diffusion so asto form a soft light similar to natural light, so that human eye health is effectively protected.

Description

technical field [0001] The invention relates to the technical field of LED lighting devices, in particular to an anti-glare ultraviolet LED lighting device. Background technique [0002] In the context of rising concerns about global energy shortages, energy conservation is an important issue we face in the future. In the field of lighting, the application of light-emitting diode (Light Emitting Diode, referred to as LED) light-emitting products is attracting the attention of the world. LED As a new type of green light source product, it must be the trend of future development. The design of living room lighting in the 21st century will be dominated by LED lighting design, and at the same time fully reflect the development trend of energy-saving, healthy, artistic and humanized lighting, and become the leading lighting culture of the living room. Research data shows that because LED is a cold light source, semiconductor lighting itself has no pollution to the environment. C...

Problems solved by technology

Among them, adding frosting effect to the LED lampshade will seriously reduce the light transmittance of the lampshade; adding toner on the basis of the original lampshade, such as barium sulfate, sodium sulfate, etc., adding these particles can make the light undergo multiple light refraction to achieve light diffusion effect, but the light diffusion effect is not obvious, and seriously affects the light transmittance; the LED lampshade adds prisms, the light diffusion effect is limited, and the dazzling LED lamp beads can still be seen, and the light transmittance is seriously reduced
