light source

New type---light source: LED uses a cold light source, with low glare, no radiation, and no harmful effects during use. The led's working voltage is low, it adopts DC drive mode, power consumption (single tube 0.03~0.06w), electro-optical power conversion is close to 100%, and it can save more than 80% energy than traditional light sources under the same lighting effect. The benefit of led ---, there is no ultraviolet and infrared in the spectrum, 應急 照明 燈and the waste can be recycled, no pollution, no hg element, safe to touch, it is a typical green lighting source.

---: LED is a solid cold light source, encapsulated by epoxy resin, anti-vibration, and the lamp has no loose parts. There are no shortcomings such as easy burning of the filament, heat deposition, light decay, etc., and the service life can reach 60,000 to 100,000 Hours, more than 10 times the service life of the light source. The LED performance is stable, and it can work normally at -30°C and 50°C.

(3) Multi-conversion: The LED light source can use the principle of red, green and blue three primary colors. Under the control of the computer, using three colors with 256 levels of gray and mixing arbitrarily, it can produce 256 256 256 (16777216) colors to form different lights. Color combination. It forms a variety of combinations of different light colors and realizes colorful dynamic changes and various images.

High-tech: LED light source is a low-voltage microelectronic product that successfully integrates computer technology, network communication technology, image processing technology and embedded control technology. The chip size used in the traditional LED lamp is 0 25mm×0 25nm, and the size of the lighting LED is generally more than 10mm×10mm. The workbench structure, the inverted pyramid structure, and the flip chip design of LED die molding can improve its luminous efficiency, thereby emitting more light. Led package design --- including high-conductivity metal block substrate, flip chip design and bare disk casting lead frame, etc., using these can design high-power, low-thermal resistance devices, and the illuminance of these devices is better than that of leds The illuminance of the product.

A typical high luminous flux LED device technology can be developed to produce a luminous flux of several lumens to tens of lumens. With updated designs, we can integrate and learn more LEDs in an important device, or install multiple electronic devices in a single assembly. , So that the number of lumens output by the students is equivalent to a small incandescent lamp. For example, a high-power 12-chip monochromatic LED device can output 200lm of light energy, and the power consumed is between 10~15W.

The application research of LED light source is very flexible and can be made into light, thin and short products with various activities of points, lines and surfaces; the control system of LED is extremely, as long as the working current is adjusted, the light can be adjusted at will; the combination of different light colors develops and changes Multi-terminal, the use of timing control module circuit, can achieve the effect of dynamic changes of rich resources LEDs have been widely used in various lighting equipment, such as battery-powered flashlights, miniature voice-activated lights, safety lights, outdoor road and indoor staircase lights, continuous lights for buildings and signs.

The emergence of white LEDs is an important step from marking function to lighting function. White LED is the closest to my country’s daylight, and can better reflect the real environment color of the target object being illuminated. Therefore, from the perspective of technical research, white LED is undoubtedly the most advanced technology of LED. White LEDs have begun to enter some application areas. products such as emergency lights, flashlights, and flashlights have been launched, but they are difficult to popularize due to their high prices. The prerequisite for the popularization of white light LEDs is that the prices continue to fall, and the price reduction must be possible after the white LED has formed a certain economic market development scale. The integration of the two ultimately depends on the progress of information technology companies.
