Description

Technical Field

[0001] The utility model belongs to the technical field of lighting systems, and in particular relates to a novel high-efficiency white light infrared two-in-one flash lighting system. Background Art

[0002] With the rapid development of the intelligent transportation industry and smart cities, there is a growing demand for monitoring fill light in intelligent transportation checkpoints, especially for monitoring of cab personnel and facial recognition during the day. Since the sunlight at noon is very strong during the day, a momentary high-energy flash is needed for fill light. However, at night, due to the dark environment, there is no need for particularly bright fill light. Therefore, infrared fill light with an infrared filter is used at night to minimize light pollution.

[0003] At present, the infrared white light in the industry generally uses high-power pulsed xenon lamps plus infrared filters. However, since the filters cannot be completely retracted, the brightness of white light during the day will be reduced, resulting in a large loss of white light. Perhaps 50% of the white light is lost during the day, resulting in low efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a novel high-efficiency white light infrared two-in-one flash lighting system to solve the problem that the filter proposed in the above background technology cannot be completely retracted, which will reduce the brightness of white light during the day and cause a large loss of white light. It is possible that 50% of the white light is lost during the day, resulting in low efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of high-efficiency white light infrared two-in-one flash lighting system, comprising: a light source lamp tube, one side of the light source lamp tube is provided with a parabolic reflection surface, the side of the light source lamp tube away from the parabolic reflection surface is provided with a spherical reflection surface, a movable filter tube is provided outside the light source lamp tube, and a transmission assembly is connected to the filter tube.

[0006] Preferably, the transmission assembly comprises an electric telescopic rod and a connecting block, the electric telescopic rod is installed on one side of the parabolic reflective surface, and the connecting block is installed between the electric telescopic rod and the light filter tube.

[0007] Preferably, a first reflection plate is provided on the parabolic reflection surface, and a first aluminum film is attached to the inner side of the first reflection plate.

[0008] Preferably, a second reflective plate is provided on the spherical reflective surface, and a second aluminum film is attached to the inner side of the second reflective plate.

[0009] Preferably, a tube sleeve is provided outside the light source lamp tube, and a through groove is opened on the first reflective plate.

[0010] Preferably, the filter tube is made of infrared glass, and the filter tube is made of multiple pieces spliced ​​into a regular polygon or a circular tube.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The utility model improves optical utilization by arranging an electric telescopic rod, a connecting block and a light filter tube. When in use, the electric telescopic rod drives the light filter tube to move left and right through the connecting block, so that the light source lamp tube is fully exposed during the day, and the light filter tube completely covers the light source lamp tube at night, thereby greatly improving the utilization rate of white light, improving optical utilization, reducing power, and reducing energy consumption, thus meeting the requirements of industry applications.

[0013] (2) The utility model enhances the lighting effect by providing a spherical reflecting surface, a first reflecting plate and a second reflecting plate. When in use, the first reflecting plate and the second reflecting plate can effectively reflect light to the area that needs to be illuminated. On the basis of the original technology, the spherical reflecting surface is added, which greatly improves the lighting efficiency and minimizes the obstruction of white light during the day.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 5 As shown, the utility model provides the following technical solutions: a new type of high-efficiency white light infrared two-in-one flash lighting system, comprising: a light source lamp tube 1, a parabolic reflection surface 2 is provided on one side of the light source lamp tube 1, a spherical reflection surface 5 is provided on the side of the light source lamp tube 1 away from the parabolic reflection surface 2, a movable filter tube 9 is provided outside the light source lamp tube 1, and a transmission assembly is connected to the filter tube 9.

[0024] Furthermore, the transmission assembly includes an electric telescopic rod 10 and a connecting block 11 . The electric telescopic rod 10 is installed on one side of the parabolic reflector 2 , and the connecting block 11 is installed between the electric telescopic rod 10 and the filter tube 9 .

[0025] Furthermore, a tube sleeve 8 is disposed outside the light source lamp tube 1 , and a through groove 12 is formed on the first reflection plate 3 .

[0026] Through the above technical solution:

[0027] When in use, the light source lamp tube 1 is placed at the focus of the parabolic reflector 2, and the tube sleeve 8 protects the light source lamp tube 1. The electric telescopic rod 10 is started, and the electric telescopic rod 10 drives the filter tube 9 to move left and right through the connecting block 11. During the day, the light source lamp tube 1 is completely exposed by controlling the filter tube 9 to move to the right. Figure 2 As shown, it can also be moved to the left to allow the light source tube 1 to be fully exposed. Figure 3 As shown, when moving to the left, the through slot 12 allows the filter tube 9 to pass through, which will lose some light energy. Figure 2 It is more efficient, but takes up more space. Figure 3 compared to Figure 2 The efficiency will be lower, but the space will be smaller and the structure will be more compact. At night, the filter tube 9 will completely cover the light source tube 1 to achieve infrared filtering effect, and there will be no white light output. This basically ensures that the blocking rate of white light during the day is less than 5%, and all is infrared at night.

[0028] See also Figure 1-Figure 5 As shown, a first reflection plate 3 is provided on the parabolic reflection surface 2 , and a first aluminum film 4 is attached to the inner side of the first reflection plate 3 .

[0029] Furthermore, a second reflection plate 6 is provided on the spherical reflection surface 5 , and a second aluminum film 7 is attached to the inner side of the second reflection plate 6 .

[0030] Through the above technical solution:

[0031] When in use, the first aluminum film 4 on the first reflecting plate 3 and the second aluminum film 7 on the second reflecting plate 6 can effectively reflect light to the area that needs to be illuminated, thereby enhancing the lighting effect. Through reflection, the light can be more evenly distributed, thereby improving the brightness and uniformity of the lighting. The focus of the parabolic reflecting surface 2 coincides with the center of the spherical reflecting surface 5. On the basis of the original technology, the spherical reflecting surface 5 is added, which greatly improves the lighting efficiency and minimizes the blocking of white light during the day.

[0032] For further information, see Figure 1-Figure 7 As shown, the filter tube 9 is made of infrared glass, and the filter tube 9 is made of multiple pieces spliced ​​into a regular polygon or a circular tube.

[0033] Specifically, the infrared glass can effectively filter out infrared wavelengths other than visible light and ultraviolet light, and the infrared glass has a high transmittance to infrared radiation. The regular polygonal or circular filter tube 9 adapts to different working environments and meets a variety of working requirements.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
