Natural-like light chip light source

Abstract

The invention discloses a natural-like light chip light source which comprises an LED constant-current driving chip, a first light-emitting assembly, a second light-emitting assembly and a third light-emitting assembly. The LED constant-current driving chip is connected with the first light-emitting assembly, the second light-emitting assembly and the third light-emitting assembly. The first light-emitting assembly comprises a silicon carbide-LED chip and yellow-green fluorescent powder. The second light-emitting component comprises a 408nm LED (light-emitting diode) chip and cyan fluorescent powder; the third light-emitting assembly comprises a gallium nitride-LED chip. The natural spectrum of the natural light-like chip light source is used as a model, light source transformation of removing valley peaks and removing rich blue is achieved, the defect that valley peak light promotes myopia and rich blue to cause eye ground damage is overcome, and damage to health is small.

Description

Technical field [0001] The present invention relates to the field of lighting fixtures, in particular to a kind of natural light chip light source. Background [0002] Fluorescent lamp luminescence is a tube filament discharge that emits ultraviolet rays from mercury vapor, which excites the phosphorus fluorescent paint on the inner surface, causing it to release other visible light of lower wavelengths. The color of the emitted light is controlled by the proportion of phosphorus components, and the spectrum of fluorescent lamps is a linear spectrum distributed on a continuous spectrum; At present, most LED lamps are excited by blue light chips to excite one or more phosphors, and eventually mixed with the light emitted by blue light and phosphors to form white light. Therefore, the spectrum of the general LED will have more than two peaks, which is also a linear spectrum, distributed on the continuous spectrum with low radiation intensity; As can be seen from the above, the spec...

Problems solved by technology

Now the commonly used LED light source is based on the sensitivity of the cone cells, ignoring the second vision and ipRGC and other non-visual channels sensitive color spectrum, so that the most important (most stable) 450-500nm blue light section in the presence of natural light presents a trough, In addition, it is mainly set in the 420-450nm segment to excite the blue light with a high peak value, forming a stronger light suppression and a relatively absent state, forming an obvious valley peak light. At the same time, the low valley section is just the core information source of natural light, and it is also the second visual channel and the non-visual channel. In the sensitive section of the spectrum, the non-visual pathway is not activated, the conduction is disordered, and the health damage of light quality is formed
