Abstract

The invention relates to a high-color-rendering-index, high-lighting-effect and high-power LED lamp. The high-color-rendering-index, high-lighting-effect and high-power LED lamp comprises a lens, a lamp shell, an LED light source, an atmospheric pressure balance device and light guide cooling liquid; and the lens is matched with the lamp shell, and a sealing cavity is formed between the lens and the lamp shell. The sealing cavity is filled with the light guide cooling liquid, the refractive index in the sealing cavity is changed, and the light losses generated when light is output to the overall lamp shell from the LED light source are reduced; the LED light source is contained in the sealing cavity and fixedly connected with the lampshell; and the atmospheric pressure balance device is installed on the lamp shell and can be communicated with the sealing cavity. The LED lamp has the beneficial effects that the radiating performance is good, the service life is long, and the color rendering index and the lighting effect are high.

Description

【Technical field】 [0001] The invention relates to an LED lamp, in particular to a high-CRI, high-luminous-efficiency, and high-power LED lamp, which belongs to the technical field of LED lamps. 【Background technique】 [0002] At this stage, LED lights adopt the method of LED light source and shell diffusion. The light output by the LED light source is irradiated between the bulbs, and then output to the irradiated target, and the light will lose 10-30%. [0003] At present, due to the bottleneck of packaging technology, the color rendering index and luminous efficacy are contradictory to each other, resulting in the problem of high color rendering index and low luminous efficacy of LED light sources; or high luminous efficacy and low color rendering index. [0004] This product adopts light guide cooling fluid technology. Make the light output between the LED light source and the lamp housing more effective. Through the characteristics of the light-guiding liquid, the col...
