Description

TECHNICAL FIELD

[0001] The utility model belongs to infrared sensor technical field, concretely relates to a kind of infrared sensor that can 360 degree detection and outdoor luminaire using the infrared sensor. BACKGROUND

[0002] The existing outdoor luminaire, such as column lamp, is provided with a human body infrared sensor. When a pedestrian enters the detection range of the human body infrared sensor after dark, the human body infrared sensor outputs a signal to light up the column lamp for illumination. When the pedestrian leaves, the column lamp is turned off to save energy.

[0003] The existing human body infrared sensor has the following defects in use: first, the detection angle of the human body infrared sensor is not large, usually only about 120 degrees. The disadvantage is that the pedestrian must be within the 120-degree range to be detected, and the remaining 240 degrees is a detection blind area, which is not convenient and has poor experience. Second, the human body infrared sensor is widely used in street lamps, park column lamps and garden column lamps. In this use scenario, in order to achieve 360-degree detection, multiple human body infrared sensors are usually installed on the column lamp to increase the detection range. The disadvantage of this design is that the number of human body infrared sensors is large, which is troublesome to assemble and wire, has low efficiency, and has no cost advantage.

[0004] Therefore, the existing technology has a human body infrared sensor that can achieve 360-degree detection. The human body infrared sensor mainly includes a shell and three infrared sensing probes. The three infrared sensing probes are uniformly distributed along the circumference of the shell and extend out of the shell. However, since the sensing angle of the existing infrared sensing probe is not more than 120 degrees, the sensitivity of the human body infrared sensor in actual use is poor (the detection effect at the sensing limit position is poor, or the detection effect at the sensing limit position is guaranteed, but the sensing distance is affected). The three infrared sensing probes are uniformly distributed along the circumference of the shell and extend out of the shell. This structure is very difficult to assemble, and is easily damaged by external forces during use. SUMMARY

[0005] The utility model aims at overcoming the deficiencies in the prior art and providing a human body infrared sensor that can achieve 360-degree detection.

[0006] To achieve the above purpose, the utility model discloses a human body infrared sensor that can achieve 360-degree detection. The human body infrared sensor includes a shell, a control assembly and at least three sensing assemblies. The control assembly is arranged in the shell. The at least three sensing assemblies are distributed along the circumference of the shell. Each sensing assembly includes a Fresnel lens and an infrared sensing probe. The Fresnel lens is in an arc-shaped sheet structure. The Fresnel lens is erected at the edge of the shell. The infrared sensing probe is electrically connected to the control assembly. The infrared sensing probe is arranged in the shell and opposite to the Fresnel lens.

[0010] The bottom of the containing chamber and the focal point chamber are respectively provided with a first drain hole and a second drain hole.

[0011] Preferably, the wiring position of the control component is opposite to the position of the first drain hole.

[0012] Preferably, the shell is provided with a hollow wire passing column and a connecting column, the inner cavities of the wire passing column and the connecting column both extend through the upper and lower ends of the shell, the inner cavity of the wire passing column is a wire passing channel, and the inner cavity of the connecting column is used for assisting the infrared sensor to be connected to the lamp.

[0013] Preferably, the control component comprises a main board, at least three probe substrates electrically connected to the main board, and at least one adjusting substrate, each probe substrate is electrically connected to an infrared sensing probe, and the adjusting substrate is electrically connected with an adjusting member.

[0014] The infrared sensor further comprises an adjusting handle, the adjusting handle passes through the shell to apply a force to the adjusting member to adjust the use parameter of the infrared sensor.

[0015] The wire passing column is located at the central position of the shell.

[0016] The main board is provided with a second avoiding hole and a third avoiding hole for avoiding the wire passing column and the connecting column.

[0017] Preferably, the bottom of the containing chamber is provided with a limiting block, and the limiting block is arranged at the rear side of the adjusting substrate and abuts against the adjusting substrate.

[0019] Preferably, the infrared sensor further comprises a wireless communication module, the wireless communication module is used for wirelessly communicating with a terminal device to control the use parameter of the infrared sensor or a device using the infrared sensor.

[0020] The utility model also provides an outdoor lamp using the infrared sensor capable of 360-degree detection.

[0021] An outdoor lighting fixture includes a lamp body, an infrared sensor, and fasteners. The infrared sensor is fixed to the lamp body by the fasteners. The infrared sensor is any of the infrared sensors described above that can detect 360 degrees.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] The sensing component of this invention specifically includes a Fresnel lens and an infrared sensor probe. The infrared sensor probe is housed within the casing, while the Fresnel lens stands upright on the edge of the casing, facing the infrared sensor probe, thus cooperating with the infrared sensor probe for detection. Because the Fresnel lens can achieve a wider detection angle, this allows the infrared sensor probe to receive a wider range of infrared signals, significantly improving its sensing angle to over 120°. Therefore, the infrared sensor can achieve 360-degree detection without affecting the sensing distance, improving the sensitivity of the infrared sensor and enhancing the performance of the lighting fixture.

[0024] The Fresnel lens has an arc-shaped sheet structure that stands upright on the edge of the housing. Compared to existing infrared sensors that require the sensor probe to protrude from the housing for detection, this design makes assembly easier due to the absence of interference from the protruding sensor probe. At the same time, the structure of the lamp housing is simpler and the manufacturing process is relatively easier. Attached Figure Description

[0054] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0055] Embodiment 1

[0056] A kind of 360 degree detection's infrared inductor, see Figures 1-3 , including shell 100, control assembly 200 and at least three induction assemblies 300.Control assembly 200 is located in shell 100;The number of induction assembly 300 of the present embodiment is three, of course, can be set to other quantities, three induction assemblies 300 are distributed along the circumference of shell 100, each induction assembly 300 includes Fresnel lens 310 and infrared induction probe 320, Fresnel lens 310 is arc-shaped sheet structure, Fresnel lens 310 is erected on the edge of shell 100, infrared induction probe 320 is electrically connected with control assembly 200, infrared induction probe 320 is located in shell 100 and opposite Fresnel lens 310.

[0057] The sensing assembly 300 of the infrared sensor of the embodiment specifically comprises a Fresnel lens 310 and an infrared sensing probe 320, the infrared sensing probe 320 is arranged in the shell 100, the Fresnel lens 310 is erected on the edge of the shell 100 and opposite to the infrared sensing probe 320, so as to cooperate with the infrared sensing probe 320 for detection. Since the Fresnel lens 310 can realize a large angle of detection, which enables the infrared sensing probe 320 to receive a larger range of infrared signals, the sensing angle is greatly improved on the basis of the existing range, more than 120°, and in practice, it can reach 170°. In this way, the infrared sensor can realize 360-degree detection without affecting the sensing distance during detection, which improves the sensitivity of the infrared sensor and improves the use effect of the lamp.

[0058] When the infrared sensor is used in the lamp, the shell of the lamp needs to be provided with a window 611 for the infrared sensor to detect. Since the infrared sensor of the embodiment has three Fresnel lenses 310 on the periphery, the shell of the lamp also needs to be provided with three windows, and the three windows will occupy most of the space of the shell of the lamp, resulting in a reduction in the strength of the shell of the lamp at the position of the window, which will affect the service life of the shell of the lamp. Therefore, in order to reduce the influence of multiple windows on the lamp, the three sensing assemblies 300 are specifically arranged at intervals along the periphery of the shell 100, and are preferably arranged in a central symmetry, so as to avoid the problem that two of the sensing assemblies 300 are in communication or close to each other, resulting in insufficient strength of the corresponding position of the shell of the lamp. The number of sensing assemblies 300 in the embodiment is preferably three, which can ensure the sensitivity of the infrared sensor and the strength of the shell of the lamp using the infrared sensor, and avoid the problem that a large number of sensing assemblies 300 need to be arranged, and a large number of windows need to be arranged on the shell, which ultimately reduces the strength of the shell of the lamp.

[0059] In the embodiment, referring to Figure 3The housing 100 has a partition 130 that divides the interior of the housing 100 into a receiving chamber 140 and a focal chamber 150. The receiving chamber 140 is located within the partition 130, and the focal chamber 150 is located between the partition 130 and the Fresnel lens 310. The control assembly 200 is located at the upper position within the receiving chamber 140, and the infrared sensing probe 320 extends into the receiving chamber 140 and is spaced apart from the bottom of the receiving chamber 140. In the above structure, a receiving compartment 140 is separated by a partition 130. The receiving compartment 140 has good waterproof performance. The infrared sensor 320 is located inside the receiving compartment 140, which can protect it from water damage. The infrared sensor 320 is located above the receiving compartment 140 and spaced apart from the bottom of the receiving compartment 140. In this way, even if water enters the receiving compartment 140, the water will flow along the inner wall of the compartment to the bottom, which will not affect the control component 200 and the infrared sensor 320.

[0060] Among them, see Figures 3-4 The partition 130 is provided with a first clearance opening 131 opposite to the infrared sensor 320, and the infrared sensor 320 can realize external detection through the first clearance opening 131.

[0061] In order to give the infrared sensing probe 320 a wider field of view, the first clearance opening 131 is a gradually enlarging horn opening 132 near the Fresnel lens 310.

[0062] When water enters the receiving chamber 140 and the focal cavity 150 through the assembly gap of the housing 100, to prevent water accumulation from damaging the electronic components, see [reference needed]. Figures 3-4 The bottom of the receiving chamber 140 and the focus chamber are respectively provided with a first drain outlet 141 and a second drain outlet 151. Water in the receiving chamber 140 and the focus chamber 150 is discharged through the corresponding drain outlets. The second drain outlet 151 at the bottom of the focus chamber 150, in conjunction with the first clearance port 131, can also improve the detection effect and the usage effect. For example, in a high humidity and foggy environment, the humid air in the focus chamber 150 will absorb and scatter infrared radiation, resulting in infrared signal attenuation and reduced detection effect. In this embodiment, since the control component 200 and the infrared sensing probe 320 are located in the receiving chamber 140, the heat generated by them in the working state enters the focus chamber 150 through the first clearance port 131 and is discharged from the sensor through the second drain outlet 151. During this process, the humid air in the focus chamber 150 liquefies and the gas humidity decreases, which greatly alleviates the impact of humid air on the infrared detection effect. The liquefied water can be discharged through the second drain outlet 151, which avoids the problem of water accumulating inside the sensor, causing the water to vaporize in the high temperature environment and affecting the sensor's detection effect again.

[0063] In the embodiment, the power supply of the control assembly 200 and the infrared sensing probe 320 is provided through the wire 400, that is, the wire 400 is needed to supply power to the infrared sensor, therefore, the above-mentioned accommodating cavity 140 not only serves as the first drain port 141, but also allows the wire 400 to pass through the accommodating cavity 140 (as shown in Figure 5 The wire 400 directly uses the first drain port 141 to pass through the wire, without opening other through holes, the structure is simple, the shell processing procedure is simplified, and in addition, the wire 400 wire passage is arranged at the bottom of the accommodating cavity 140, compared with being arranged at the side wall or the top, the problem that external water enters the cavity body and damages electronic components can be avoided.

[0064] The wire 400 directly uses the first drain port 141 to pass through the wire, without opening other through holes, the structure is simple, the shell processing procedure is simplified, and in addition, the wire 400 wire passage is arranged at the bottom of the accommodating cavity 140, compared with being arranged at the side wall or the top, the problem that external water enters the cavity body and damages electronic components can be avoided.

[0065] In the embodiment, referring to Figure 3 , the shell 100 is provided with a hollow wire passing column 160 and a connecting column 170, the inner cavities of the wire passing column 160 and the connecting column 170 penetrate through the upper and lower ends of the shell 100, the inner cavity of the wire passing column 160 is a wire passing channel 161, so that for the power supply or the light source of part of the lamps above the infrared sensor, the wire 400 can pass through the wire passing channel 161 upwardly after passing out of the first drain port 141 and be connected to the power supply or the light source (as shown in Figure 6 The inner cavity of the connecting column 170 is used to assist the infrared sensor to be connected to the lamp, specifically, in the embodiment, the inner side wall of the connecting inner cavity 171 of the connecting column 170 is a stepped surface with a wide upper part and a narrow lower part, and the infrared sensor can be fixed to the lamp through a screw.

[0066] In the embodiment, the wire passing column 160 is protruded from the top surface of the shell 100 to form a boss 162, so that the water on the top surface of the infrared sensor shell 100 cannot flow into the wire passing channel 161, and the use safety is ensured.

[0067] In the embodiment, the top surface of the connecting column 170 is flush with the top surface of the shell 100, so that the hollow connecting column 170 not only can fix the infrared sensor to the lamp, but also can make the water flow into the inner cavity of the connecting column 170 and flow out through the gap between the screw and the inner side wall of the cavity when the water accumulates on the top surface of the infrared sensor shell 100.

[0068] In the embodiment, the shell 100 includes a shell main body 110 and an upper cover 120, wherein, referring to Figure 4 , Figure 7The shell body 110 is provided with a plurality of lower partitions 111 and a plurality of positioning columns 112, and the upper cover 120 is provided with a plurality of upper partitions 121 and a plurality of positioning holes 122. During assembly, the upper cover 120 is fixed on the shell body 110 through interference fit of the positioning columns 112 and the positioning holes 122. After assembly, the upper partitions 121 cooperate with the corresponding lower partitions 111 to form the above-mentioned partitions, and the above-mentioned accommodating cavity 140 and focal cavity 150 are formed. The shell body 110 is provided with a U-shaped notch 113 at a position opposite to the first avoiding opening 131, and the U-shaped notch 113 is provided with a U-shaped clamping groove 114. The bottom of the upper cover 120 is provided with a strip-shaped clamping groove 123 opposite to the U-shaped notch 113. During assembly of the Fresnel lens 310, the Fresnel lens is first clamped in the U-shaped clamping groove 114. After the upper cover 120 is fixed on the shell body 110, the strip-shaped clamping groove 123 of the upper cover 120 clamps the top of the Fresnel lens, so as to fix the Fresnel lens 310 on the shell 100. Referring to Figure 8 The Fresnel lens 310 is provided with a notch 311 at the lower side, and the U-shaped notch 113 of the shell body 110 is provided with a matching reinforcing rib 115. During installation of the Fresnel lens 310, the cooperation of the two can prevent the Fresnel lens 310 from being assembled in the wrong direction. The shell body 110 and the upper cover 120 are respectively provided with two lower hollow columns 116 and upper hollow columns 124. After the shell body 110 and the upper cover 120 are assembled, the lower hollow columns 116 and the corresponding upper hollow columns 124 are connected to form the above-mentioned wire passing column 160 and the connecting column 170.

[0069] In the embodiment, referring to FIG. 9, the control assembly 200 includes a main plate 210, at least three probe base plates 220 electrically connected to the main plate 210, and at least one adjusting base plate 230. Specifically, the probe base plates 220 of the embodiment are three, and each probe base plate 220 is electrically connected to an infrared sensing probe 320. The adjusting base plate 230 is electrically connected with an adjusting member 231, which is specifically an adjustable resistor. The infrared sensor further includes an adjusting handle 500, which can apply a force to the adjusting hole of the adjustable resistor through the shell to adjust the use parameter of the infrared sensor. For example, the adjusting handle 500 is a knob handle, and rotating the knob handle can adjust the sensitivity parameter of the sensor, or adjust the brightness, light-on time, etc. of the lamp using the sensor, which is the prior art and will not be described here.

[0070] The main plate 210 is provided with a second avoiding hole 211 and a third avoiding hole 212 for avoiding the wire passing column 160 and the connecting column 170. In this way, when the main plate 210 is installed, the main plate 210 is sleeved on the wire passing column 160 and the connecting column 170 through the second avoiding hole 211 and the third avoiding hole 212. The main plate 210 is placed on the positioning column 112 through the through hole thereof. When the upper cover 120 is closed, the upper cover 120 presses the main plate 210, so as to fix the main plate 210 in the shell 100.

[0071] The through line post 160 is located at the center of the shell 100, and the connecting post 170 is located at the side of the through line post 160 close to the adjusting handle 500. In this way, the through line post 160 can pass through the center of the main plate 210 and is limited from the center of the main plate 210, which can improve the assembly stability and reliability of the main plate 210. When the adjusting handle 500 is assembled or used, the user applies force to the adjusting handle 500, and the adjusting handle 500 pushes the adjusting base plate 230, which causes the adjusting base plate 230 to be offset and affects the connection reliability of the adjusting base plate 230 and the main plate 210 and the performance of the main plate 210. Therefore, the connecting post 170 is arranged close to the adjusting handle 500. When the adjusting handle 500 applies force, the adjusting handle 500 is further limited by the connecting post 170, which can reduce the influence of the adjusting handle 500 on the main plate 210 and improve the assembly reliability. The bottom of the accommodating bin 140 is provided with a limiting block 117, which is arranged at the rear side of the adjusting base plate 230 and abuts against the adjusting base plate 230. This can prevent the adjusting base plate 230 from being offset rearward.

[0072] In the embodiment, the top surface of the upper cover 120 is provided with a word mark 125 of “THISSIDE UP”, which is convenient for identification and use.

[0073] In the embodiment, the three probe base plates 220 can be provided with LED indicator lights 250 according to actual assembly requirements. When the adjusting function or the human activity is sensed, the LED indicator light 250 emits corresponding flicker. The photosensitive tube 260 is also provided, which controls the starting LUX of the lamp. In the case that the daytime or the ambient light is sufficient, even if a person enters the detection range, the light will not be turned on, which plays a role in energy saving.

[0074] Embodiment 2

[0075] A 360-degree detection infrared sensor, which has basically the same structure as that of the embodiment 1, and the difference is that in the embodiment 1, the number of the adjusting handle 500 is two, and the two adjusting handles 500 are arranged in the vertical direction and located between the two Nephelium lenses. In the embodiment, referring to Figures 10-12 , the adjusting handle 500 and the adjusting base plate 230 are three, one adjusting handle 500 cooperates with one adjusting base plate 230 to control, and each adjusting handle 500 is arranged between two adjacent sensing assemblies 300.

[0076] In addition, in Embodiments 1 and 2, the infrared sensor and its operating parameters are adjusted using the adjustment handle 500. In this embodiment, the sensor may not have the adjustment handle 500. Instead, a wireless communication module 240 can be installed in the sensor to communicate wirelessly with the infrared sensor. For example, the wireless communication module 240 can be an IR receiver tube, which can be used to set the sensor and thus the lighting function via a remote control. Alternatively, it can be a conventional wireless communication module such as Bluetooth or WIFI, which allows the terminal device to control the sensor parameters and the brightness and duration of the lighting of the lamp using the sensor.

[0078] An outdoor lighting fixture 600, such as Figure 13 As shown, this 600 lamp is a multi-head lamp, such as... Figures 13-15 As shown, the device includes a lamp body 610, an infrared sensor, and a fastener 620. The infrared sensor is the same as that in Embodiment 1. The fastener 620 is a screw that passes through the inner cavity of the connecting post 170 of the housing 100 and is threadedly connected to the lamp body, thereby fixing the infrared sensor to the lamp body 610 by means of the fastener.

[0079] in, Figure 13 Only one outdoor lighting fixture appearance is shown; of course, the outdoor 600 can also adopt such an appearance. Figure 16 Pillar lamps.

[0080] Alternatively, depending on the housing of the infrared sensor, it can also be used in lighting fixtures with other appearances. Specifically, Figures 14-15 The infrared sensor housing shown is cylindrical, but it can also be like... Figures 17-18 The shape, and corresponding structural diagrams of its application in multi-head lamps and pole lamps, are shown below. Figures 19-20 As shown.
