Solar spike lamp with long-lasting phosphor materials

Abstract

A solar spike lamp with long-lasting phosphor materials comprises a housing (1), the long-lasting phosphor materials (2), one or more LED light sources (3), a power storage element (4), a solar photovoltaic device (5), a control circuit board (6), optical elements (7), retroreflective materials (8) and package resin (9), wherein the control circuit board (6) intermittently supplies power to the one or more LED light sources (3) at a certain duty ratio or at a certain cycle. According to the solar spike lamp with the long-lasting phosphor materials, the stroboflash fluctuation depth is reduced by utilizing the long-lasting energy storage luminescence characteristic, and the power consumption of the power storage element (4) is reduced by reducing the duty ratio or lengthening the period; based on the principle, the novel all-weather solar spike lamp with stronger functions and higher safety and environmental protection property can be designed and manufactured, not only is the original function improved, but also the auxiliary illuminating lamp function is integrated under the condition of not increasing the power consumption, and thus the application range is expanded greatly.

Description

technical field [0001] The invention relates to an outdoor luminous device, in particular to a solar road stud lamp with a long afterglow luminescent material, which can not only have the warning function of a traditional solar road stud, but also have an auxiliary lighting function. [0002] technical background [0003] 1. With the progress of society and the development of transportation, the concept of green roads has been widely disseminated and increasingly popular, and the service objects of road lighting are no longer limited to motor vehicles but have been extended to pedestrians and non-motor vehicles. [0004] 2. As a kind of road stud, which is mainly installed in the middle of road markings or between double yellow lines, has the function of luminous or reflective, and serves as a guiding or warning traffic safety guidance sign for motor vehicle drivers, it has been widely used in existing the way. [0005] 3. Conventional road studs rely on retroreflective mate...

AI Technical Summary

Problems solved by technology

[0005] 3. Conventional road studs rely on retroreflective materials to reflect the lights of passing vehicles to provide passive lighting, which cannot get rid of the dependence on car lights, and can only induce motor vehicles

However, its luminous brightness is low, and it is only suitable for rural roads and scenic roads. The use is very limited and the use effect is not ideal.

[0007] 5. Ordinary photoelectric road studs, such as the patent No. CN 102280040 A, require a large amount of electric energy for daily use, and do not meet the requirements of the era of green transportation

This mode consumes a lot of electric energy, so the capacity of the electric storage element has a strict limit on the light-emitting time; and because the human eye is more likely to notice the dynamic scene, the constant light mode of this road stud is not conducive to causing damage to motor vehicle drivers. Warning function; finally, the long-time power supply mode is more likely to cause damage to components due to high operating temperature in summer

[0012] Especially in rainy or snowy days, the solar battery is not fully charged, so that it cannot work effectively, and it is almost a decoration

[0013] Based on the above problems, the application of traditional solar road studs has been greatly restricted
