Description
Technical Field
The invention relates to the technical field of LED illumination detection, in particular to a low-blue-light adjustable LED detection light source.
Background
A Light-emitting diode (LED) is a semiconductor electronic Light-emitting device composed of trivalent and pentavalent elements. The current passes through the semiconductor and, when combined with the holes, releases energy in the form of photons. This mechanism of luminescence, known as electroluminescence, was first discovered by uk engineer R.J Round at 1907. Specifically, LEDs are like ordinary diodes, and are fabricated in p, n architectures by implantation or doping. Current in an LED can only flow from the p-pole (anode) to the n-pole (cathode). The different electrode voltages cause holes and electrons to flow from the electrodes to the p, n architecture. When two different carriers, a hole and an electron, meet and recombine, the electron falls to a lower energy level and releases energy in the form of a photon. The color emitted by the electroluminescence of an LED is determined by the energy of the forbidden band of the PN semiconductor. These forbidden band energies correspond to light energies in the near infrared, visible, or near ultraviolet bands. The LED originally invented was made of gallium arsenide (GaAs), and was low in luminous efficiency and only capable of emitting red or infrared light, and was used only for indicator lamps. It has been discovered that adjusting the energy band of a semiconductor can produce light of different colors by allowing electrons to release different energies when traversing the energy band. White light can be produced by mixing a number of different semiconductor LEDs, or by down-mixing blue light through a phosphor.
The LED has the advantages of high efficiency, long service life, difficult damage, high reaction speed, high reliability and the like which are beyond the reach of the traditional light source. Currently, the present invention has been applied to various fields such as status display lamps, traffic lights, backlight sources for LCD displays, optical communication, road lighting, indoor lighting, and the like.
With the development of the potential of the LED applied to the general illumination field, the global LED illumination market is developed at a high speed, and the main growth sources of the global LED illumination market are backlight lamps, landscape illumination, general illumination, outdoor LED large screens, building illumination, car lamps and the like. As LED technology matures, the global LED lighting penetration will further increase.
The conventional light source is limited in the mechanism of light emission, and the actual feeling of light by human eyes is rarely considered in the design. Light is a special physical quantity that has both physical and physiological properties. The brightness of the light perceived by the human eye is not only related to the luminous intensity of the light source itself, but also related to the distance of the light source. The illumination and photometry of light are respectively derived according to the intensity of the light source and the intensity of light perceived by human eyes. Due to the special configuration of the human eye, the human eye perceives different brightness for different wavelengths of light for a beam of light of the same power.
The human eye typically perceives light between 380nm and 788nm, and beyond this range, light of a wavelength is not visible to the human eye. The intensity of the emitted light is the same, the green light is brightest to the human eye, and the light of wavelengths further away from the green light, such as red and blue light, is perceived as less bright to the human eye. The peak of the human visual function is at 555nm for bright vision and 507nm for dark vision as shown in the following figure. Therefore, under different scenes, a light source most suitable for human eyes can be designed by adjusting the RGB ratio based on the characteristic of LED multi-element light emission.
At present, the main index of the lighting industry is the Color Rendering Index (CRI), but the CRI is inaccurate for narrow half-wave-width light sources such as LEDs, and compared with a high-pressure sodium lamp with a higher CRI index, an LED light source with a lower CRI index can bring better visual effect. Since CRI is the comparison of the light source spectrum to 10 standard hues and then averaging. Such an index does not provide a ready indication of the display capability of the light source, i.e. the capability of displaying the original color of the object.
Furthermore, most of the white LEDs currently on the market are generated by blue LEDs through fluorescence excitation. The light excited in this manner contains a large blue component. Excessive blue light can damage visual cells of people and inhibit melatonin synthesis of human bodies, so that sleep disorder is caused.
