Low-color-temperature lighting component

Abstract

The invention provides a low-color-temperature lighting component which comprises a circuit board and one or a plurality of light source units. Each of the light source units is fixed on the circuit board and comprises white-light LED light sources and red-light LED light sources with peak wavelength ranging from 620-650nm, and the white-light LED light sources and the red-light LED light sources are connected in parallel or in series and are distributed in array. After the red-light LED light sources with the peak wavelength ranging from 620-650nm are combined with the white-light light sources, the low-color-temperature lighting component with color temperature lower than 2500K is obtained. Being tested, light emitted by the low-color-temperature lighting component does not include ultraviolet light, so that aging of objects being irradiated and burning of human skins can be avoided. Meanwhile, the low-color-temperature lighting component without mercury is environment-friendly.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to a low color temperature lighting assembly. Background technique [0002] Lamps with a color temperature of light below 2500K are generally called low color temperature lamps, and low color temperature lamps have a wide range of application markets in certain lighting occasions. However, traditional low color temperature lighting mostly uses mercury lamps as the excitation light source, and the generated ultraviolet rays excite red phosphors, which are then mixed to produce low color temperature light. The ultraviolet rays contained in the light irradiated by such lamps will accelerate the aging of the illuminated object and even cause damage to the illuminated object. When it is irradiated on the human body, it will burn the human skin; and the conversion efficiency of the red phosphor is low, which makes the traditional low color temperature lamps The light effect is generally aroun...

AI Technical Summary

Problems solved by technology

The ultraviolet rays contained in the light irradiated by this type of lamp will accelerate the aging of the illuminated object and even cause damage to the illuminated object. When it is irradiated on the human body, it will burn the human skin; and the conversion efficiency of red phosphor powder is low, which makes the traditional low color temperature lamps The light effect is generally around 40lm / W

At the same time, because the lamps contain mercury, they will cause serious pollution to soil and water after being discarded.

Therefore, in today's increasingly tense energy environment and the pursuit of green environmental protection and sustainable development, low color temperature lamps produced by traditional manufacturing methods are increasingly unable to meet the needs of society and development
