Description

Technical Field

[0001] The utility model relates to the field of multi - primary - color street lamps, and particularly to a phosphor - free multi - primary - color street lamp supporting dynamic lighting. Background Art

[0002] In the existing street - lamp system, the color and color temperature of lighting are usually fixed and cannot be dynamically adjusted according to the changes of environmental conditions. This not only affects the lighting effect but also causes energy waste. Especially for traditional LED street - lamp light sources, which mainly rely on the combination of blue - light LED chips and yellow - light phosphors, their color temperature is fixed and cannot be adjusted according to factors such as time, temperature, and weather. In harsh environments such as heavy rain and fog, they cannot provide effective lighting effects. The increase in the temperature of the phosphors in the LED street - lamp light source will also lead to problems such as a decrease in conversion efficiency, attenuation of light performance, and carbonization of the phosphor glue.

[0003] In addition, high - color - temperature and fixed - color - temperature LED street lamps also have light - pollution problems. Their blue - light components may pose potential hazards to surrounding organisms, such as inhibiting the secretion of melatonin, leading to problems such as biological - clock disorders and sleep disorders. To solve these problems, a new type of LED street lamp is needed that can intelligently adapt to environmental changes and dynamically adjust the lighting effect at different time periods, different temperatures, and different climate conditions.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0019] Reference Figure 1 , a phosphor-free multi-primary color street lamp supporting dynamic lighting, including a lamp body 1. The lamp body 1 can be a fixed housing, serving as the fixed support for the entire multi-primary color street lamp, and can be formed by manufacturing processes such as extrusion aluminum, die casting, and sheet metal; a street lamp connector 2 is provided on one side of the lamp body 1 for connecting to an external power supply. A plurality of LED light sources 3 are provided on the lamp body 1 for providing lighting. An output power supply 4 and a sensing component 5 are also provided on the lamp body 1. The output power supply 4 is electrically connected to the street lamp connector 2 and the plurality of LED light sources 3, and the output power supply 4 is electrically connected to the sensing component 5.

[0020] The plurality of LED light sources 3 includes a substrate 31. The substrate 31 is made of one of an aluminum substrate, a glass fiber substrate, a ceramic substrate, or a paper substrate, having good heat dissipation performance and stability. The substrate 31 is fixedly provided on the side of the lamp body 1 away from the street lamp connector 2 to ensure sufficient installation space and heat dissipation space for the LED lamp beads 32; a plurality of LED lamp beads 32 are encapsulated on the substrate 31. The LED lamp beads 32 are phosphor-free lamp beads, which is prior art and will not be elaborated here; the colors and color temperatures of these LED lamp beads 32 can be more than two kinds. For example, they include multiple colors such as red, green, and blue, as well as multiple color temperatures such as cold color and warm color. By controlling the brightness and combination mode of the LED lamp beads 32 with different colors and color temperatures, rich light color effects can be generated to meet different lighting requirements.

[0021] The output power supply 4 is located on the side of the lamp body 1 close to the street lamp connector 2 and can be embedded in the lamp body 1. It includes a constant voltage module and a constant current module. The constant voltage module can convert the alternating current of the commercial power supply of 220V into the supply voltage required by each module of the power supply to supply power to each module; the constant current module can accurately output multiple paths of constant current according to the control information of the control unit to drive the plurality of LED light sources 3 to emit light, thereby realizing different lighting effects. An induction component 5 is electrically connected between the constant voltage module and the constant current module. The signal of the induction component 5 can affect the output of the constant voltage module and the constant current module, thereby realizing the dynamic adjustment of the brightness and light color of the plurality of LED light sources 3.

[0022] The induction component 5 includes a rain sensing module, a temperature and humidity sensing module, an ambient light sensing module, a weather forecast module, and a clock module, and are all electrically connected to the constant voltage module, the constant current module, and the control unit. The sensing head of the induction component 5 can protrude from the surface of the lamp body 1 for easy sensing of the external environment, making the sensing data more accurate.

[0023] The rain sensor module can detect whether raindrops fall on the street lamp, collect the amount of rainfall, and send the rainfall information to the control unit; the temperature and humidity sensor module can collect the temperature and humidity of the environment and send the temperature and humidity information to the control unit; the ambient light sensor module can collect the change of ambient light intensity and send the ambient light intensity change information to the control unit; the weather forecast module obtains external weather forecast information through the built-in network module and sends the information to the control unit to provide the future weather conditions for the control unit; the clock module is used to provide accurate time information for the control unit to ensure that the street lamp can work according to the preset mode at different time periods.

[0024] The control unit is electrically connected to both the output power supply 4 and the sensing component 5. It can analyze and calculate based on the information provided by the sensing component 5, and apply an algorithm to convert the information of each sensing module into the current constant current control information required by the constant current module. The control unit sends the constant current control information to the constant current module, and the constant current module adjusts the brightness and light color of the multi-channel LED light source 3 through multiple outputs, enabling the multi-color street lamp to intelligently adapt to environmental changes at different time periods, different temperatures, and different climate conditions, and dynamically adjust the lighting effect. For example, when the street lamp starts to light at 6 pm, it can simulate the light color of the setting sun to enhance the urban landscape; during the peak period, it can emit positive white light to increase the vehicle passing efficiency; after 11 pm, it can automatically reduce the power and emit low-color warm light to reduce light pollution to the residents on both sides of the street and improve sleep quality. In rainy or foggy weather, it can simulate the light color of a sodium lamp. In a thick fog environment, the light of different wavelengths has different penetrations. The visible distance of red light in thick fog is 8 - 10 meters, the visible distance of yellow light in thick fog is 7 - 8 meters, the visible distance of green light in thick fog is 5 - 6 meters, and the visible distance of blue light in thick fog is 2 - 3 meters. That is to say, when in thick fog, the multi-channel LED light source 3 can achieve a prominent effect. Among them, the light with a wavelength of 560 - 580 NM has strong penetration and the strongest penetration.

[0025] The specific working principle is as follows:

[0026] When the street lamp is turned on, the sensing component 5 starts to work, detects the environmental information and sends it to the control unit. The control unit calculates the brightness and light color of the multi-channel LED light source 3 that is most suitable for the current environment based on the received information, and realizes the dynamic adjustment of the brightness and light color of the multi-channel LED light source 3 by adjusting the constant voltage module and constant current module of the output power supply. At the same time, the control unit can also adjust the brightness and light color of the multi-channel LED light source 3 in advance according to the information provided by the weather forecast module to cope with the upcoming climate change.

[0027] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
