Abstract

The invention discloses a three-primary-color LED street lamp based on mesopic vision on the basis of a mesopic visiontheory. The three-primary-color LED street lamp comprises high-power LED lamp beads with three colors, namely red, blue and green, a radiator, a lampshade and a driving power supply. According to the three-primary-color LED street lamp, the wavelength of the blue lamp bead is in the scope of 490 nanometers to 500 nanometers; the wavelength of the green lamp bead is in the scope of 520 nanometers to 530 nanometers; and the wavelength of the red lamp bead is in the scope of 620 nanometers to 630 nanometers. The three lamp beads cover one another, the color developing of the illuminating effect is warm white, and in the environment of mesopic vision, S/P can be effectively improved, an object can be clearly distinguished, and energy consumption can be effectively reduced.

Description

A kind of three-primary-color LED street lamp based on mesopic vision

Technical field

The invention belongs to field of LED illumination, relate to a kind of three-primary-color LED street lamp based on mesopic vision.

Background technology

Eyes cone cell according to people is different from the effect degree of rod cell, and vision can be divided into vision improvement, scotopic vision and mesopic vision; In vision improvement situation, cone cell works, perception to external world is the center of object, color, distinguish object fast, spectrum sensitivity peak value is 555nm, in scotopic vision situation perception to external world be object profile, can not distinguishing colours, distinguish that object is slow, spectrum sensitivity peak value is 507nm, brightness is more than 3cd/m²For vision improvement, lower than 0.001cd/m²For scotopic vision, falling between as mesopic vision, under mesopic vision state, express highway pavement is 2cd/m², good street lighting road surface 1cd/m²; Research shows, spectral luminous efficiency curve under mesopic vision environment is constantly skew, vision improvement is at 555nm place, scotopic vision is at 507nm place, therefore, in the design of actual illumination, select near luminous efficiency maximum as far as possible, which improves brightness, make lighting quality obtain change, also save the energy greatly.

Summary of the invention

The present invention, it is simply that according to above-mentioned viewpoint, it is provided that a kind of three-primary-color LED street lamp based on mesopic vision.

A kind of three-primary-color LED street lamp based on mesopic vision, including the large-power LED light bead of three kinds of colors red, blue, green, radiator, lampshade and driving power supply.

Described a kind of three-primary-color LED street lamp based on mesopic vision, blue lamp bead selects wavelength in the wave-length coverage of 490nm��500nm; Green lamp bead selects wavelength in 520nm ~ 530nm wave-length coverage; Red lamp bead selects wavelength in the wave-length coverage of 620nm��630nm.

Described a kind of three-primary-color LED street lamp based on mesopic vision, blue lamp bead selects the high-power lamp bead of 3w; Green and red lamp bead selects the high-power lamp bead of 1w.

Described a kind of three-primary-color LED street lamp based on mesopic vision, the proportioning that three primary colours lamp bead blue, green, red selects is: 1 is blue: 8 is green: 3 is red.

Accompanying drawing explanation

Fig. 1 is a kind of three-primary-color LED street lamp lamp bead structural representation based on mesopic vision.

Description of reference numerals: the green lamp bead of the blue lamp bead 3 of 1 HONGGUANG lamp bead 2.

Detailed description of the invention

As shown in Figure 1: the proportioning of lamp bead blue, red, green is 1:3:8, is fixed on aluminium base by lamp bead, is then fixed on street lamp heat radiator by lamp bead substrate, connects driving power supply, puts cushion rubber well, street lamp is fixing according to being placed on above cushion rubber.Street lamp waterproof to accomplish IP65 grade; Blue lamp bead wavelength is 490nm��500nm, green lamp bead wavelength is chosen as 520nm��530nm, red lamp bead wavelength is 620nm��630nm, they cover mutually, the colour developing of its illuminating effect is warm white, under mesopic vision environment, can effectively improve S/P, distinguish object clearly, effectively save power consumption.
