Description
Technical Field
The invention belongs to the technical field of intelligent street lamps, and particularly relates to a manufacturing method of a wide-angle street lamp light source and an intelligent street lamp thereof.
Background
The energy shortage and the environmental pollution make energy conservation and environmental protection become main topics of people, white Light Emitting Diodes (LEDs) have high color saturation and long service life, and LED illuminating lamps become main research and development directions of people. The existing LED street lamp is to install LEDs on a planar substrate and form a lattice on the substrate. Each LED emits a cone of light whose coverage is related to LED divergence angle, illumination distance, and the number, power, etc. of LEDs.
Meanwhile, under the influence of different atmospheric environments, the irradiation effect of the LED street lamp can be greatly influenced, such as fog, rain, snow and other weather, light rays can be reflected and refracted, and the visibility and the visual perception threshold of human eyes can be reduced. The irradiation distance is increased, the LED with large divergence angle is selected, the brightness is increased, the irradiation area is increased, and the penetration and illumination of the environment under the weather conditions can be effectively improved. However, as the coverage area increases, the illuminance decreases greatly, and the substrate area and the number of LEDs increase, so that the coverage area can be only slightly enlarged, and the cost increases sharply. The use of a fluorescent cover material containing a rare earth element can increase light transmission efficiency, but the use of a rare earth element adversely affects economy and environment.
LED quantum dots, also known as quantum dot light emitting diodes (QLEDs), are a new type of light emitting diode, employing quantum dots as the luminescent material. While conventional LEDs use semiconductor materials such as gallium nitride (GaN), LED quantum dots use nano-scale semiconductor crystals, quantum dots. The quantum dots have excellent properties in the aspect of optical characteristics, so that the LED quantum dots are greatly improved in the aspects of color performance, brightness and energy efficiency. The principle of luminescence of LED quantum dots is that when electrons are excited in the quantum dot, they release photons, and their energy is related to the size of the quantum dot. By controlling the size and the composition of the quantum dots, the luminous color of the LED quantum dots can be controlled, so that wider color expression is realized, and meanwhile, the smaller processable light source volume is convenient for the lighting equipment with a wide angle to be realized by combining the flexible substrate.
In order to improve the flexibility, stability and light efficiency of the intelligent street lamp, expand the irradiation range, and reduce the use and dependence of the high-transmittance fluorescent cover on rare earth elements, it is necessary to provide a manufacturing method of a wide-angle street lamp light source and the intelligent street lamp thereof.
