led point light source is ideal as a particle led point light source. led point light source is an abstract physical concept, in order to simplify the study of physical problems. Just like the smooth plane, particle, and no air resistance usually said, the led point light source does not exist in reality, referring to the light source that emits uniform light from a point to the surrounding space.
led point light source is ideal as a particle led point light source. led point light source is an abstract physical concept, in order to simplify the study of physical problems. Parallel light sources, also known as DirectionalLight, are a group of parallel rays without attenuation, similar to the effect of sunlight. The target parallel light produces a cylindrical region of parallel illumination, which is a kind of "parallel beam" similar to the target spotlight. The target parallel light is mainly used to simulate the effect of sunlight, searchlight, laser beam, etc.
Outdoor lighting project led, that is, light-emitting diode, is a light-emitting device made of semiconductor homogenous PN junction, heterogeneous PN junction, metal-semiconductor (MS) junction, metal-insulator-semiconductor (MIS) junction. Its working principle and some electrical properties are the same as those of ordinary crystal diodes, but the crystal materials used are different. Leds include visible light, invisible light, laser and other different types, and the common ones in life are visible light leds. The luminous color of LED is determined by the material used, currently there are yellow, green, red, orange, blue, purple, cyan blue, white, full color and other colors, can be made into rectangular, circular and other shapes. led has the advantages of long life, small weight, small power consumption (energy saving), low cost, low operating voltage, high luminous efficiency, extremely short luminous response time, wide operating temperature range, light color pure, solid structure (impact resistance, vibration resistance), stable and reliable performance, and a series of characteristics, much favored by people.
Because the luminous body of the led is close to the "point" light source, the lamp design is more convenient, but if it is used as a large-area display, the current and power consumption are larger. led can generally be used for electronic equipment indicator light, digital tube, display board and other display devices and optocouplers, but also commonly used in optical communication, as well as the outline of buildings, amusement parks, billboards, streets, stages and other places of decoration.
led point light source intelligent beacon lamp is the scientific research results of Yantai navigation beacon Office in 2011, it uses a single led as a light source, through the free-form side luminous lens to control the light path, to achieve low power consumption, high range, low maintenance, long life, after technical testing, to meet the requirements of the relevant technical standards. The new navigation light optical system matching the free-form side light lens with the led point light source led is an important technical innovation realized by the modulator.
