Background and Trends in the Construction of Intelligent Transportation
1、 In recent years, with the rapid development of economic construction, there has been a significant improvement in the level of urbanization and motorization, resulting in a rapid increase in transportation demand, leading to increasingly prominent urban transportation problems. Traffic congestion causes serious waste of time resources, chaotic operation, and traffic safety accidents result in a large number of casualties and property losses, seriously hindering the healthy development of urban socio-economic and environmental conditions; To this end, strengthening refined urban management, adopting advanced intelligent traffic management technologies, fully tapping and integrating public resources, improving the order, safety, and efficiency of urban road traffic system operation, have become the main content of building smart transportation;
2、 Currently, cameras used for road traffic monitoring (such as traffic light intersections, speeding, and capturing violations) require the use of fill lights to capture clear images or videos. Typically, one camera, one LED strobe light, and one gas flash light are installed on each lane. Install cameras and fill lights at intersections or lanes. The more lanes there are, the more cameras and fill lights need to be installed, resulting in a dense and unsightly appearance of lighting fixtures on the road. In addition, flash lights emit instantly bright white light when supplementary lighting is needed. At night, the instantly bright light can cause significant glare to the eyes of drivers, non motorized lanes, or pedestrians, which may cause instant blindness and pose a safety hazard. This is currently an urgent problem to be solved.
The urgent problems that need to be solved in the field of intelligent transportation lighting
Fengshang Optoelectronics Joint Solution for Light Supplement
To solve the problems of glare caused by fill lights at night and too many monitoring pole lights, Fengshang Optoelectronics has developed a four in one fill light, which has four functions: LED strobe, LED burst, white light flash, and infrared flash; It can effectively reduce the number of installed fill lights, lower the cost of lighting fixtures, and enhance the aesthetics of the city.
Working mode of lighting fixtures:
During the day: The LED components of the lighting fixtures do not emit light to save energy, and when a flash is needed for strong light suppression, white light flashes;
At night: The LED strobe light is turned on, and the LED burst function can also be used; Gas flashing lights convert to infrared flashing, as infrared light is not visible to the human eye, it will not cause glare to drivers, non motorized lanes, or pedestrians, eliminating discomfort or safety hazards caused by ordinary lighting fixtures.

Introduction to Fengshang Optoelectronics Environmental Protection Light Supplement - Composition
Composed of a four in one fill light.
1. Gas flash section: composed of xenon lamp tube and reflective cup, which can determine the angle of light output of the lamp;
2. Infrared conversion component, consisting of a filter and a driving motor. When the component is in operation, the motor rotates to drive the filter to rotate and fold or open;
3. LED strobe section: surrounded by 24 LED components on the outer ring, the LED components include LED chips, lenses, which can determine the angle of light output of the lamp and have two functions: strobe and burst;
4. Head: Made of die-casting aluminum material, the LED components, lamp tubes, and infrared conversion components are installed on the head and fixed with screws; There are 32 heat dissipation fins on the head;
5. Front cover: Transparent PC plastic material;
6. Glass: 4mm thick tempered glass; The front cover and glass are bonded with waterproof and high-temperature resistant adhesive, and a silicone waterproof rubber ring is installed between the front cover and the head and fixed with screws;
7. Lamp body: Aluminum extrusion molding, internal circuit board installed, lamp body and back cover, silicone waterproof rubber ring padded in the middle of the head, fixed with screws
8. Rear cover: Die cast aluminum material;
9. Rain shield: Made of ABS material, it serves as a rain shield, sunshade, and thermal insulation;
10. Support: Die cast aluminum material, used for fixing lamps.
Introduction to Fengshang Optoelectronics Environmental Protection Light Supplement - Working Mode
Install the four in one fill light on the road crossbar and connect the camera;
During the day: The lighting fixtures are adjusted by the camera's output signal, the LED components are turned off and do not emit light, and the filter of the infrared conversion component is in a folded state; When a car passes by on the road, the camera begins to capture. When the sunlight is strong during the day, the parts of the road or vehicle surface that are directly exposed to sunlight are brighter, and areas that are not directly exposed to sunlight will produce deeper shadows. If supplementary lighting is not carried out, the details of the shaded areas will not be captured clearly; In this situation, the xenon tube of the lamp emits light, and the xenon tube emits an instantly bright white light to fill in the shaded area, making the captured photo clear and not missing any details.
At night: The lighting fixtures are adjusted through the output signal of the camera, and the LED components emit light (flickering or exploding). The infrared conversion component filters are in a unfolded state; When a car passes by on the road, the camera starts capturing, and at this time, the camera will output a signal to the lighting fixtures, increasing the power of the LED flicker (or burst) of the lighting fixtures to achieve high-definition recording purposes; At the same time, when captured by the camera, the xenon tube of the lamp emits an instantly bright white light. The light passes through the filter of the infrared conversion component, filtering out the light that is irritating to the human eye. The remaining light with wavelengths of 780-850nM passes through the filter, and the camera can capture infrared light, making the captured photos clear and without missing any details; Due to the fact that the human eye is not visible to light with a wavelength of 780nM or higher, there will be no glare to the driver's cabin, non motorized lanes, or pedestrians when supplementing the light.
Advantages of Fengshang Optoelectronics Solution

2. A lighting fixture solves various lighting problems (LED strobe, LED flash, strong light suppression during the day, infrared flash at night).
3. Each camera only needs to be equipped with one lighting fixture (traditional lighting fixtures require LED strobe and gas flash), reducing installation and maintenance costs.
4. The lighting fixtures have self checking and self-protection functions, automatically adapt to camera output signals, and can be remotely controlled and software upgraded.
5. Improve the aesthetics of cities and roads.
