Description

Solar stud light with long afterglow luminescent material

Technical field

The utility model relates to an outdoor illuminating device, in particular to a solar stud lamp with a long afterglow luminescent material which can have the warning function of the traditional solar road stud and the auxiliary lighting function.

technical background

1. With the development of society and the development of transportation, the concept of green highway has been widely spread and has become more and more popular. The service targets of highway lighting are no longer limited to motor vehicles and are widened to pedestrians and non-motorized vehicles.

2. As a kind of traffic safety induction sign which is mainly installed in the middle of the marking line of the road or in the middle of the double yellow line, it has the function of illuminating or reflecting, and guiding or warning the driver of the motor vehicle has been widely used. the way.

3. Conventional traditional spikes rely on retroreflective material reflection to provide passive illumination to the vehicle's vehicle lights. They cannot get rid of the dependence on the car's lighting, and can only induce the motor vehicle.

4. In 2015, the Ministry of Communications promulgated the People's Republic of China Transportation Industry Standard “JT/T 967—2015 Highway Energy Storage Self-illuminated Traffic Sign”, which specifies the application standards for the long afterglow spike. The long afterglow nail combines the long afterglow luminescent material with the conventional traditional spike, and has the functions of reflection and self-illumination, which not only induces the motor vehicle, but also can induce and indicate the pedestrian and the non-motor vehicle. . However, its illuminating brightness is low, and it is only suitable for rural roads and scenic highways. The use is very limited and the effect is not satisfactory.

5. Ordinary photoelectric spikes, as taught by patent number CN 102280040 A, the daily use of such photoelectric spikes requires a large amount of electrical energy and does not meet the requirements of the era of green transportation.

6. The existing solar road spikes are divided into convex and embedded, and the principle is basically as described in patent number CN103452057A, which has the function of utilizing solar energy active light. There are two types of solar road spikes: one is stroboscopic and the other is always bright. The fatal disadvantages are as follows:

The LED light source of the solar spike is all lead-type LED straw hat light, the light-emitting area and the light-emitting inclination angle are small, and the light is glare; and in order to achieve the dynamic warning effect, the flash frequency is generally between 90 and 120 times per minute, which will make Excessive fatigue of the retina damages the optic nerve; and this excessive stroboscopic pattern can easily cause irritability and pose a safety hazard, especially for non-motorized drivers or ordinary pedestrians.

On the other hand, solar road spikes generally use intermittent power supply strobe mode, and the lighting is turned on and off alternately. When the light is extinguished, there is no other component to illuminate. If the interval of extinguishing is too long, it will suddenly fall into the dark and cause blindness. As shown in Figure 2-1. Therefore, the existing solar spikes can only adopt a high-frequency flicker mode with extremely large fluctuation depth, and the application is limited to a limited field such as warning.

On the other hand, some solar spikes use a continuous power supply steady light mode. This mode consumes a large amount of electric energy, so that the capacity of the storage element has strict limits on the lighting time; and because the human eye is more likely to notice the dynamic scene, the constant light mode of the spike is not favorable for the motor vehicle driver. In the end, the long-term power supply mode makes it easier for components to be damaged due to excessive operating temperatures during the summer.

Especially in rainy or snowy days, the solar battery is not fully charged, making it impossible to work effectively, almost becoming a display.

Based on the problems described, the application of traditional solar spikes has been greatly restricted.

7. Within the scope of the existing technical conditions, it is necessary to consider factors such as overall luminous performance, size limitation, compressive strength, waterproof performance, ease of installation, etc., and balance economical (production cost), service life and practicability (can Improving the existing products and meeting the new requirements of road lighting. The relationship between the three is the problem that solar road nails have plagued for more than 20 years since its invention.

8. In view of the problem of the existing spike, the utility model proposes a vehicle that is never reported and never appeared in the existing market, and covers the motor vehicle, the non-motor vehicle driver and the pedestrian. , a green-green all-weather solar spike lamp with dynamic warning function, small stroboscopic fluctuation depth, low frequency flash, low glare, and continuous illumination auxiliary illumination function, thus breaking through the existing solar road spike The technical bottleneck solves the problem and opens up new fields for the application of solar spikes.

This solar Studs longlasting as compared to conventional spike: spike general longlasting afterglow luminance after three hours is generally ² or less 70mcd / m, the afterglow luminance after 8 hours in 30mcd / m ² or less, 2 midnight After the point, it is almost impossible to provide an effective guiding effect, and the product of the utility model can maintain the luminous brightness of 10000mcd/m ² or more throughout the night, and the luminous brightness of the latter half of the night is more than 100 times that of the conventional long afterglow luminous nail, so it can also be used in the latter half of the night. Provide normal lighting or guidance for pedestrians.

Compared with the ordinary photoelectric spikes, the utility model has the advantages that the utility model does not need to consume the commercial power, and the emitted light is more eye-protecting and greener and healthier.

Compared with conventional solar road spikes, the solar energy spikes of the utility model have the following advantages: ordinary solar road spikes may have insufficient storage energy of the storage elements due to insufficient illumination of the light and fog, so that the LED light sources cannot continuously and effectively emit light; or due to electronic components or A situation in which the line is damaged and cannot be illuminated. However, the utility model has an intermittent power supply with a longer period or a lower duty ratio, thereby greatly improving the effective illumination time of the LED light source; even if the electronic component or the line is damaged, it can still rely on the long afterglow to play a certain role. Luminescence induction. Therefore, the integrated illuminating performance is superior and the adapting surface is very broad. Utility model content

1. The biggest difference between the utility model and the existing solar road spike is that a long afterglow luminescent material is introduced. When the LED light source is energized, part of the light emitted by the LED is absorbed by the long afterglow, and part of the light passes through the long afterglow body to emit light. The LED light source is extinguished intermittently, and the long afterglow luminescent material continues to maintain illumination, so the work is repeated as shown in Figure 2-2. Therefore, the power consumption of the solar spikes is smaller, which not only can increase the illumination duration of the existing solar spikes, but also provides more power consumption for us to design more illumination modes; the traditional solar spikes are changed intermittently. The mode is capable of continuous illumination and reduces the depth of the stroboscopic fluctuations, and the emitted light is more eye-protecting.

2. Different from existing solar road nails and long afterglow nails, the utility model combines long afterglow and solar road nails, and preferably blue or violet or ultraviolet light source with a peak wavelength of 450 nm or less for long afterglow luminescent materials. Excited to enable rapid and sufficient excitation of long afterglow luminescent materials.

3. Preferably, the original straw hat type LED light source is replaced by an SMD package LED array light source, and is disposed at a lower portion of the long afterglow luminescent material as a backlight, thereby increasing the light emitting area and more uniformly exciting the long afterglow illuminating material.

4. The utility model can intermittently supply power with a longer period or a lower duty ratio than the existing solar road spikes, thereby making full use of the long afterglow luminescent material after a strong excitation for a few minutes (or even a few seconds). The ultra-high brightness inside makes it able to maintain the brightness of 10000mcd/sqm or more at night. Ordinary long afterglow nails are excited by the natural light of the outside world. During the period when the sun light becomes weak to disappear in the evening, the light can not effectively excite the long afterglow luminescent material, so the illuminance of the illuminating light is below 100mcd/sqm after 10pm. Therefore, the luminous intensity of the solar stud light of the utility model is more than 100 times that of the conventional long afterglow nail lamp in the latter half of the night, thereby solving the problem that the ordinary long afterglow nail is insufficient in brightness during outdoor use, so that the long afterglow The application field of spikes has been greatly expanded.

5, ordinary solar road spikes in the rain and fog days due to insufficient ambient illumination, resulting in insufficient storage of electrical energy storage components, so that the LED light source can not continue to effectively emit light; or due to damage to electronic components or lines can not be illuminated. However, the utility model has intermittent power supply by using a longer period or a lower duty ratio, which reduces the limitation of the storage element capacity on the illumination duration; and the stored energy storage element is exhausted, or the electronic component or In the case of damaged lines, it is still possible to rely on the long afterglow characteristics of the long afterglow luminescent material to induce a certain effect: thus, it is possible to continuously emit light all the time.

6. Ordinary solar road spikes can only adopt high-frequency flash or constant-light illumination mode with large fluctuation depth, which limits the wider application of solar road spikes; and the utility model breaks through the technology of existing solar road spikes from the principle of illumination. bottleneck. The utility model can not only follow the conventional short-cycle or large duty-cycle high-frequency flashing illumination mode, but also reduce the fluctuation depth of the stroboscopic light by long afterglow illumination, thereby maintaining the original solar road spike warning function. On the basis of the reduction of glare and strobe damage to the human eye; can also use a longer period or a smaller duty cycle of the low-frequency flashing light mode, can maintain dynamic warning and continuous illumination of the auxiliary lighting function Therefore, not only can the vehicle be alerted and guided, but also provide auxiliary lighting for pedestrians and non-motorized vehicles, so that the service object can be fully covered: different cycle or duty cycle illumination modes are used according to actual needs, and the shape is slightly changed. Or fixed component structure, you can design different corners of the solar road stud light products: can be used for road pavement, but also can be installed on curbstones, warning pillars, road railings, steel fences, anti-collision piers, etc. It can be used in outdoor living places such as parks, greenways, courtyards, and residential areas, and the scope of application is greatly expanded.

7, due to the combination of long afterglow luminescent materials, using its energy storage characteristics, under the same design conditions, can greatly save the power consumption of the circuit, so the device can be more miniaturized, design smaller micro-studded lights, and even button spikes Lights, etc. The installation cost is even lower, and it can even be installed in various mobile transportation facilities, including automobiles, construction facilities, mobile traffic signs, etc., completely opening up new application fields.
