Solar light with Forward Angle and Hazardous Area Lighting {Solar Light with Forward Angle and Hazardous Area Lighting}

The present invention relates to a solar warning light having a forward direction angle and a hazard area lighting function. More specifically, it is equipped with a solar charger and can be installed in a dangerous area regardless of the installation location to guide the gaze of drivers and pedestrians at night. It relates to a solar-powered warning light that has a forward direction angle and a hazard area lighting function.

Conventional warning lights have been mainly used attached to the top of police cars, and recently, they have been attached to streetlights or poles to draw the driver's attention in dangerous areas such as speeding areas, sharp curves, and cliff sections on highways or national roads. It is being used.

This type of long warning light has 4 to 6 luminescent lamps with a rotatable reflector arranged in a row on one side of the interior, and a case made of red, blue, etc. synthetic resin surrounds the exterior. The case is made of a translucent material, and the luminous lamp is mainly a lamp containing xenon gas.

The long warning light turns on at night and twinkles as the reflector rotates to draw the attention of drivers on the road. To drive these long warning lights, wires were connected from the outside or power from batteries was used.

Therefore, in order to continuously supply power to long warning lights, electric wires had to be pulled to the roadside or batteries had to be supplied periodically. This method is not only inconvenient to manage, but also causes the inconvenience of having to provide a power line during installation or replace the battery periodically. Accordingly, there is an emerging need to provide semi-permanent power supply to drive long warning lights without considering separate power lines and batteries.

Meanwhile, road signs are installed on roads to provide road information and traffic guidance to pedestrians and vehicle drivers. Road signs provide information to pedestrians and drivers, such as directions, speed limits, and hazard signs.

Road signs can be broadly divided into non-illuminated and illuminated types. Non-illuminated signs are road signs that emit light by reflecting light from vehicle headlights, but do not have their own light source. In contrast, illuminated road signs have a separate light source that provides light. These illuminated road signs are divided into an external lighting type in which a lighting device installed on the outer upper part or ground part of the sign illuminates the road sign to make it appear bright, and an internal lighting type in which the road sign is configured to be brightly displayed by the output light of a lighting device installed inside the road sign. can be distinguished.

The visibility of illuminated road signs is much better than that of non-illuminated signs. Compared to non-illuminated road signs, illuminated road signs are known to be about 1.6 times better in nighttime visibility. Because this excellent visibility can greatly improve driving safety and reduce the possibility of traffic accidents, the spread of illuminated road signs has been gradually expanding in recent years.

Meanwhile, due to global warming and climate change, there is a worldwide demand for the development of new clean energy and alternative energy that can suppress carbon dioxide emissions rather than energy from oil, coal, etc.

As shown in Figure 1, the present invention is a pair of high-output LED modules that alternately light or flash in mutually inverted colors and transmit a wink or visible signal to notify vehicles moving in all directions of a dangerous area and prevent the driver's vision from being obstructed during the day and night. A visible light emitting unit (11) including an automatic angle downward adjustment function, a power unit (13) that charges and stores power produced from solar cells, a BMS charging unit (30) having functions for monitoring the status of solar cells and monitoring the battery status, The BMS charging unit has a monitoring and control function, and through setting the LED cross-lighting time and cross-lighting change settings of the visible light-emitting unit, the visible light-emitting unit is radiated 15 degrees downward from the horizontal direction of the road to prevent visibility obstruction at night. It includes a control unit 20 with a control function.

In addition, as shown in FIG. 2, the present invention includes a lower lighting unit 12 that operates at night among the pair of high-output LED modules and informs of a dangerous point below the lower part of the visible light emitting unit where a warning light is installed.

The visible light emitting unit 11 is composed of a pair of red and white high-output LEDs, and can quickly notify a dangerous point by turning the power on and then turning it off for only a few tens of msec during a one-second cycle. The lower part notifies the dangerous point below the bottom. Glare can also be prevented by tilting the lighting unit at a certain angle based on the horizontal line of the road.

In addition, the pair of high-output LEDs can visually notify drivers or pedestrians of dangerous areas ahead during the day or at night through a lighting and flashing structure in red and white, up and down or left and right.

As shown in Figure 3, the visible light emitting unit drives an electromagnet or a servo motor, and when operating horizontally at night, there is a risk of obstructing the driver's vision at night due to the straightness of the light source of the light emitting unit. Therefore, when operating at night, the visible light emitting unit is moved in the horizontal direction through the control unit. A 10 to 15 degree downward control operation is performed to block straight-forward light sources, thereby reducing glare for drivers at night.

The present invention uses LED as a light source, reducing power consumption, improving the lifespan of the light source, thus reducing operating costs, and adjusting the up and down angles as a whole or individually according to the number of lanes to illuminate the entire lane evenly, improving driver comfort. The improved visibility not only provides an improved safe driving environment, but also prevents driver glare.

In addition, by varying the irradiation angle of the light generated from each high-output LED installed in the main frame and irradiated to the road, light can be irradiated uniformly across the entire lane regardless of the number of lanes and lane width, reducing glare for drivers. It can be prevented.

In addition, since it is not erected on a high pole but is installed on a road railing or road structure about 1m high, the installation height is low and the amount of light lost due to the shortened distance from the road is small, enabling sufficient lighting even when using low-intensity LEDs. , It is installed identically to the road line and functions as a lane guide to prevent road departure accidents.

In addition, since it is installed on road railings or road structures at a height of about 1m, it is lower than the driver's viewing height, preventing dazzle to the driver. In addition, the light scattered in the event of fog is relatively small, enabling more effective lighting, and there is no backlight, so the surrounding area of the road is protected. Plants and insects are not illuminated at night, so they do not cause disturbance to the ecosystem.

In particular, for example, the control operation is performed downward by 10 to 15 degrees at night, and the light emitting unit is returned to horizontal during the day. The control unit determines the day or night classification based on the output voltage of the solar cell.

Meanwhile, the LED light emitting device includes a plurality of LEDs each having a radiation flux of a predetermined size under predetermined conditions; a plurality of lenses, each at least partially disposed in front of each of the LEDs; and a substrate on which the plurality of LEDs are mounted.

At night, a plurality of LEDs are controlled downward by 15 degrees, and during the day, the light emitting unit is returned to the horizontal state. The control unit determines the day or night classification based on the output voltage of the solar cell.

In addition, the lower lighting unit made of a plurality of LEDs is made of white high-output LEDs and is located at the bottom of the equipment. It can be turned off during the day and operated only at night, and the control unit 20 is responsible for this function.

Among the plurality of LEDs, at least two LEDs have different sizes of the radiation beam, and each lens may have a different shape depending on the size of the radiation beam of each LED corresponding to the lens.

Accordingly, the shape of the lens disposed in front of the LED can be adjusted for each LED according to the size of the radiation flux under predetermined conditions of the LED. Accordingly, since the amount of light irradiated in front of each LED can be adjusted, the uniformity of the amount of light irradiated in front of the LEDs for each position can be effectively improved.

Therefore, by adjusting the shape of the lens placed in front of the LED, it can be controlled downward by 15 degrees, and the light emitting part can be returned to horizontal during the day.

In addition, since the amount of light irradiated in front of the LED is uniform for each position, the effective irradiation area that can be satisfied can be increased only when the amount of light in a predetermined range is irradiated uniformly.

Accordingly, the utilization of LEDs can increase and the production and management costs of LEDs can be reduced.

Accordingly, when the maximum forward voltage is applied to each LED, the difference in radiation flux between LEDs having different sizes of radiation flux can be maximized.

Accordingly, the shape of the lens disposed on each LED is changed based on the case where the difference in radiation flux is maximized, so optical uniformity can be effectively improved.

According to an embodiment of the present invention, at least two LEDs with different sizes of the radiation flux may have different peak wavelengths.

Accordingly, even when the LED includes a plurality of LEDs that emit light having different peak wavelengths, the amount of light radiated to the front of the LED can be uniform depending on the position.

According to an embodiment of the present invention, the shape may be a ratio of the thickness to the diameter of the lens.

Accordingly, lenses of different shapes can be easily manufactured at low cost depending on the size of the radiation flux under certain conditions of the LED, and the refractive index of light emitted from the LED can be easily adjusted.

According to an embodiment of the present invention, the ratio of the thickness to the diameter of each lens may increase as the size of the radiation flux of each LED corresponding to the lens decreases.

Accordingly, under certain conditions, the light of the LED with a small radiation flux can be concentrated on the front of the LED, and under certain conditions, the light of the LED with a large radiation flux can be dispersed rather than concentrated on the front of the LED.

Accordingly, since the amount of light irradiated in front of each LED can be adjusted to be uniform, the uniformity of the amount of light irradiated in front of the LEDs for each position can be effectively improved.
