Problems solved by technology

However, the high-color-rendering white LED disclosed in this document has the following technical problems: (1) The white light of the high-color-rendering white LED is mainly formed by exciting phosphor powder from the blue LED, so it has high energy in the 435-480nm band. The represented blue light has a strong stimulating effect on the retina of the human eye and is easy to damage the retina of the human eye
[0010] So far, there is still no lighting source that is harmless to humans

Embodiment 1

[0043] figure 2 It is a structural schematic diagram of a new white LED lighting device according to an embodiment of the present invention. image 3 It is a plane view of an LED chip of a novel white LED lighting device according to an embodiment of the present invention. Figure 4 It is a schematic cross-sectional structure diagram of a novel white LED lighting device according to an embodiment of the present invention.

[0044] A kind of novel white light LED illuminating device shape of the present embodiment is pear-shaped (such as figure 2 shown). The light emitting module is made up of LED chips 212 of white light, green light and red light (such as image 3 As shown), the chip 212 is fixed on the fixing ring 210 by the screw 211, and the light emitted by the chip 212 can be concentrated through the metal focusing shell 205. The high reflection film is glued on the glass (or plastic) lampshade, and the glass or plastic lampshade is embedded in the groove 206 of th...

Abstract

The invention discloses a novel LED (light emitting diode) light source and an illumination device thereof, belonging to a light emitting system and device. Because the existing white light LED spectrum is in a narrower belt shape, is incomplete in color, higher in color temperature and lower in color rendering and has non-soft and discordant lights to eyes, in the invention, through reducing the blue light peak value in the white light LED light source, and supplying green and red light components in the white light LED spectrum, the spectrum is continuous and widened, thus the aim of the modification of the origional light source is achieved.

Description

technical field [0001] The invention belongs to the field of lighting engineering, and in particular relates to a lighting system and a device, in particular to an LED light source and a lighting device thereof. Background technique [0002] Current lighting sources mainly include incandescent lamps, halogen lamps, fluorescent lamps, and LED lamps. Although they have brought convenience to humans, they have their own advantages and disadvantages. [0003] An incandescent lamp refers to a light source that generates visible light by heating certain metal substances and using thermal radiation. The spectral distribution of incandescent light is continuous, and it is a continuous spectrum in the visible light part. , the energy distribution of incandescent light is mainly concentrated in the region with longer wavelengths, so there are strong short-wave infrared rays in its light components. Short-wave infrared rays have a strong ability to penetrate the eye tissue, and after ...
