People are used to seeing things in the sun. For general lighting, people need mainly light sources close to the quality of sunlight, so white LEDs are an important indicator of semiconductor lighting technology. LEDs are compact, lightweight, low-drive, full-color, long-life, high-efficiency, vibration-resistant, and easy to control light, providing superior conditions for lighting systems designed for different locations and purposes. Since the single LED has low power and low brightness, it is not suitable for use alone. Therefore, it is necessary to assemble a plurality of LEDs together to design a practical LED lighting system. However, there is still a certain distance between the requirements of white LEDs and general lighting, and there are still many technical and cost issues that need to be solved urgently.
The main technical overview of semiconductor lighting system The thermal management of the lighting system is often referred to as LED as a cold light source. This is because the principle of LED lighting is that electrons directly emit photons through recombination without the need for heat. However, due to the existence of Joule heat, LEDs also have heat accompanying illumination, and for high power and multiple LED applications, the heat accumulation is small and cannot be underestimated. LEDs are different from traditional illumination sources such as incandescent lamps and fluorescent lamps. Excessive temperatures can shorten or even terminate their service life. Moreover, LEDs are temperature-sensitive devices. When the temperature rises, their efficiency drops sharply. Therefore, system structure design and heat dissipation technology development are also issues that LED applications need to face. Since forced air cooling is generally undesirable in light sources, heat sinks and other methods of enhancing natural convection cooling play an increasingly important role in LED lamp and light source design as input electrical power increases.
Improve color rendering At present, white LEDs are commonly used to emit blue light by superimposing yellow-emitting yttrium aluminum garnet (YAG) phosphors excited by blue light. Since the luminescence spectrum contains only two spectra of blue and yellow, there is a problem that the color temperature is high and the color rendering index is low, which does not meet the general lighting requirements. The sensitivity of the human eye to chromatic aberration is much higher than the sensitivity to light intensity. For illumination, the color rendering of a light source is often more important than the luminous efficiency. Therefore, adding an appropriate amount of red-emitting phosphor and maintaining high luminous efficiency is an important issue in LED white light illumination.
Secondary optical design of luminaire system Traditional luminaires have long used incandescent and fluorescent light sources as reference materials to determine the optical and shape standards of luminaires. Therefore, LED luminaire systems should consider abandoning the traditional luminaires and LED lighting modules. Optical characteristics, specially designed for LED light sources. The design content of the optical system mainly includes the following aspects: (1) according to the requirements of the illumination object and the luminous flux, determine the shape of the optical system, the number of LEDs and the size of the power; 2 design a plurality of LED lighting tubes into a point light source, a ring light source or The secondary light source of the surface light source calculates the illumination optical system according to the combined secondary light source; 3 the light distribution control of each LED tube on the secondary light source that constitutes the illumination optical system design is very important.
Since the beam emitted by the LED is concentrated, it is easier to control, and the reflector is not required to be concentrated, which is advantageous for reducing the depth of the lamp. For example, with a flat mirror optical system, a large surface can be illuminated with only 1 or 2 LEDs, and the depth of the lamp is very thin. With the light guide technology, the LED is directly mounted next to the light pipe, which can greatly reduce the light source and other components. The volume occupied makes an ultra-thin luminaire.
Improve the reliability of the system. Some people call it a long-life lamp. As a solid-state light-emitting device, its theoretical life is over 100,000 hours. Its service life is much longer than that of traditional light sources. Therefore, it is used in some places where it is difficult to replace and maintain. The cost can be greatly reduced. However, in many practical applications, this advantage cannot be seen. Instead, the user sees that the light decay is severe and the life span is short. It takes less than 10,000 hours to break down. This is because the LEDs used by everyone are The Ф3~Ф5mm LED, which is the most commonly used indicator function in the electronics industry, uses a simple electronic circuit to increase the current to increase its luminous intensity. However, the LED only obtains a short high brightness, but loses the life expectancy of the LED. Therefore, LEDs should be carefully selected in the design of semiconductor lighting fixtures, and high-power LEDs should be used as lighting sources.
Increasing luminous flux and lowering prices Currently, a single 1W LED device has a luminous flux of about 25lm, a good quality price of more than $5, and a poorer price of $3. The luminous flux of 25lm is too small for general illumination. The luminous flux of an ordinary 60W incandescent lamp is more than 700lm. That is to say, instead of traditional lighting, multiple LED devices are needed, plus the driving circuit, lamp housing and lamp holder. Etc., such a high cost is the biggest problem of white LEDs in general lighting. In particular, the efficiency is currently 25 to 45 lm/W, which needs to be further improved.
The integration of power supplies, circuits and luminaires is an LED design luminaire. One problem that designers need to pay attention to incandescent and fluorescent luminaires is the power supply. Most incandescent lamps are powered directly from an AC line, so no power is required. Fluorescent lamps use ballasts to perform the function of the power supply. However, the LED needs a special power supply and drive circuit to match it. When designing the luminaire, the power supply and the luminaire system should be considered. The biggest features of semiconductor lighting and solar power generation are environmental protection, energy saving, long life and safety. Solar energy and semiconductor lighting combine to achieve photoelectric to electro-optic conversion, which is the best combination. The natural energy-utilizing independent semiconductor lighting fixture with solar cell power generation as the power source saves energy, environmental protection and long life, and also saves related wires and supporting facilities, and has huge market space.
