Description

Technical Field

[0001] The utility model relates to the technical field of supplementary lighting, in particular to a novel LED and spiral lamp tube coaxial integrated supplementary lighting system. Background Art

[0002] With the rapid development of the intelligent transportation industry and smart cities, there is a demand for monitoring fill light in intelligent transportation checkpoints during the day, especially for monitoring of cab personnel and face recognition. In addition, because the sunlight at noon is very strong, up to 100,000 lux, ordinary light fill light cannot meet the requirements at all, and the camera cannot clearly capture the situation in the cab. Therefore, a high-brightness flash is needed to fill light for taking pictures in the cab, and LED stroboscopic fill light is needed at night to perform video detection of motor vehicle license plates and real-time detection and capture of motor vehicle snapshots. At present, the industry generally uses high-power pulse xenon lamps, and the light source is a spiral lamp tube. At night, multiple LED light sources are used to arrange a circle of LED stroboscopic fill light around the parabolic reflective surface of the large xenon lamp spiral lamp tube.

[0003] In the prior art, fill-in lighting fixtures are large in size and high in cost during use, which reduces their economic practicality. To this end, we propose a new LED and spiral tube coaxial integrated fill-in lighting system to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art that the fill light lighting fixtures are large in size and high in cost during use, thereby reducing the economic practicality, and to propose a new LED and spiral lamp coaxial integrated fill light lighting system.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A novel LED and spiral tube coaxial integrated fill light illumination system, comprising:

[0007] a first parabola and a second parabola;

[0008] An LED light source is mounted on the second parabola and is located at the focal position of the second parabola. The LED light source is used to emit light in the positive direction of the Z axis. The second parabola is used to reflect the light emitted by the LED light source once and emit it along the positive direction of the Z axis to the illuminated surface;

[0009] The spiral lamp tube light source is located at the focal position of the first parabola, and the first parabola is used to reflect a part of the light emitted by the spiral lamp tube light source and emit it along the positive direction of the Z axis.

[0010] Furthermore, the focus of the first parabola coincides with the center of the spherical surface, and the first parabola is used to reflect the light reflected by the spherical surface for a second time and then emit it along the positive direction of the Z axis.

[0011] Furthermore, the first parabola, the second parabola and the spherical surface are all made of aluminum metal.

[0012] Furthermore, the second parabola is connected to a spherical surface, and the spherical surface is used to reflect another part of the light emitted by the spiral lamp tube light source to the first parabola.

[0013] Furthermore, the reflecting surfaces of the first parabola, the second parabola and the spherical surface are all coated with aluminum film.

[0014] In the utility model, the novel LED and spiral lamp tube coaxial integrated supplementary lighting system has the following beneficial effects:

[0015] 1. In this scheme, when the spiral lamp light source emits light, a part of it is directly reflected by the first parabola, emitted along the positive direction of the Z axis, and reaches the illuminated surface. The other part is reflected by the spherical surface for the first time and reaches the first parabola. After the second reflection, it is emitted along the positive direction of the Z axis. In this way, basically more than 90% of the light passes through the reflection and collimation effect of the first parabola, which greatly improves the efficiency of the optical system and the emission angle is also very small, which can be about 15 degrees.

[0016] 2. In this solution, when the LED light source emits light in the positive direction of the Z axis, it is reflected once by the second parabola and emitted along the positive direction of the Z axis to the illuminated surface. The aperture of the second parabola is less than or equal to the aperture of the spherical surface, and the light of the spiral lamp tube light source will not be blocked at all.

[0017] The utility model can combine the spiral lamp tube lighting focusing system and the LED array fill light system into one, reduce the number of lamps, reduce the structural size, and improve the efficiency at the same time. It can also reduce the fill light angle, improve the optical efficiency, reduce costs, reduce light pollution, and improve the efficiency of lamps, reduce power, and reduce energy consumption, thus meeting the needs of industry applications very well.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Reference Figure 1-Figure 7 , a new type of LED and spiral tube coaxial integrated fill light lighting system, including:

[0028] A first parabola 1 and a second parabola 2;

[0029] LED light source 4, LED light source 4 is located at the focal position of the second parabola 2, LED light source 4 is used to emit light in the positive direction of the Z axis, the second parabola 2 is used to reflect the light emitted by the LED light source 4 once and emit it along the positive direction of the Z axis to the illuminated surface, the LED light source can be one or more light sources, such as 4 in a 2*2 arrangement, 8 in a 2*4 arrangement, 9 in a 3*3 arrangement, 16 in a 4*4 arrangement, etc.;

[0030] The spiral lamp tube light source 5 is located at the focal position of the first parabola 1. The first parabola 1 is used to reflect a part of the light emitted by the spiral lamp tube light source 5 once and emit it along the positive direction of the Z axis. The focus of the first parabola 1 coincides with the center of the spherical surface 3. The first parabola 1 is used to reflect the light reflected by the spherical surface 3 for a second time and then emit it along the positive direction of the Z axis. The first parabola 1, the second parabola 2 and the spherical surface 3 are all made of aluminum metal. The second parabola 2 is connected to the spherical surface 3. The spherical surface 3 is used to reflect another part of the light emitted by the spiral lamp tube light source 5 to the first parabola 1. The reflecting surfaces of the first parabola 1, the second parabola 2 and the spherical surface 3 are all coated with aluminum film. Figure 6 As shown in FIG. 1 , the illumination distribution diagram of the spiral tube light source 5 illuminating a position 10 meters away, the maximum illumination at the center reaches 450,000 Lux; Figure 7 As shown, the illumination distribution diagram of the LED light source at a distance of 10 meters has a central illumination of 1600 Lux. The first parabola 1, the second parabola 2 and the spherical surface 3 are all made of aluminum metal spinning or aluminum die-casting, or plastic injection molding. The spherical surface 3 is recommended to be made of metal spinning or aluminum die-casting. A part of the light emitted by the spiral lamp tube light source 5 at the focus is directly reflected and collimated by the first parabola 1, and the other part is reflected by the spherical surface 3, returns to the focus, and then is collimated and emitted through the first parabola 1.

[0031] The implementation principle of a novel LED and spiral tube coaxial integrated fill light illumination system in the embodiment of the present application is as follows: based on the original technology, the spiral tube illumination focusing system and the LED array illumination system are combined into one, without affecting the original spiral tube illumination optical system. The specific principle is that the spiral tube light source 5 is placed on the focus of the first parabola 1, and the focus of the first parabola 1 coincides with the center of the spherical surface 3. A part of the light emitted by the spiral tube light source 5 directly passes through the first reflection of the first parabola 1, and is emitted along the positive direction of the Z axis to reach the illuminated surface. The other part passes through the first reflection of the spherical surface 3 to reach the first parabola 1, and is emitted along the positive direction of the Z axis after the second reflection. In this way, basically more than 90% of the light passes through the reflection collimation effect of the first parabola 1, which greatly improves the efficiency of the optical system. The emission angle is also very small, which can be about 15 degrees. Figure 3 As shown, even by adjusting the focal length of the first parabola 1 and the radius of the spherical surface 3, the emission angle can reach about 10 degrees; the LED light source 4 is placed at the focus of the second parabola 2, and the LED light source 4 emits light in the positive direction of the Z axis, and after a reflection from the second parabola 2, it is emitted along the positive direction of the Z axis to the illuminated surface, as shown in FIG. Figure 4 and Figure 5As shown, the aperture of the second parabola 2 is smaller than or equal to the aperture of the spherical surface 3, and the light of the spiral lamp tube light source 5 will not be blocked at all. The spiral lamp tube light source 5 and the LED light source 4 can work simultaneously or separately.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
