Description

Technical Field

[0001] The invention belongs to the technical field of infrared sensors, and in particular relates to an infrared sensor capable of 360-degree detection and an outdoor lamp using the infrared sensor. Background Art

[0002] Existing outdoor lamps such as column lamps are equipped with human infrared sensors. After dark, when pedestrians step into the detection range of the human infrared sensor, the human infrared sensor will output a signal and light up the column lamp for lighting. When the person leaves, the column lamp will go out to save energy.

[0003] Existing human infrared sensors have the following defects when in use: First, the detection angle of the human infrared sensor is not large, usually only about 120 degrees. The disadvantage is that pedestrians must be within the range of 120 degrees to be detected, and the remaining 240 degrees are detection blind spots, which have poor convenience and experience; Second, human infrared sensors are widely used in street lamps, park and garden column lights. In this usage scenario, in order to achieve 360-degree detection, multiple human infrared sensors are generally installed on the column lights at the same time to increase their detection range. The disadvantage of this design is that due to the large number of human infrared sensors, assembly and wiring are troublesome, efficiency is low, and there is no cost advantage.

[0004] To this end, there is a human infrared sensor that can achieve 360-degree detection in the prior art. The human infrared sensor mainly includes a shell and three infrared sensing probes, which are evenly distributed along the circumference of the shell and extend out of the shell. However, since the maximum sensing angle of the existing infrared sensing probes does not exceed 120 degrees, the sensitivity of the human infrared sensor in actual use is poor (the detection effect of the sensing limit position is poor, or the sensing distance is affected while the detection effect of the sensing limit position is guaranteed). The three infrared sensing probes are evenly 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 of the invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an infrared sensor capable of 360-degree detection.

[0006] To achieve the above purpose, the present invention discloses an infrared sensor capable of 360-degree detection, comprising a shell, a control component and at least three sensing components, wherein the control component is arranged in the shell, and the at least three sensing components are distributed along the circumference of the shell, and each sensing component comprises a Fresnel lens and an infrared sensing probe, wherein the Fresnel lens is an arc-shaped sheet structure, and the Fresnel lens stands upright on the edge of the shell, and the infrared sensing probe is electrically connected to the control component, and the infrared sensing probe is arranged in the shell and opposite to the Fresnel lens.

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

[0014] The infrared sensor further includes an adjustment handle, which passes through the housing and applies a force to the adjustment member to adjust the use parameters of the infrared sensor;

[0015] The wire passing column is located at the center of the housing;

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

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The induction assembly of the present invention specifically includes a Fresnel lens and an infrared sensing probe. The infrared sensing probe is arranged in a housing, and the Fresnel lens stands upright at the edge of the housing and is opposite to the infrared sensing probe, so as to cooperate with the infrared sensing probe for detection. Since the Fresnel lens can achieve detection at a larger angle, the infrared sensing probe can receive infrared signals in a larger range, and its sensing angle is greatly improved on the basis of the existing range, exceeding 120°. In this way, when the infrared sensor detects, it will not affect the sensing distance on the basis of achieving 360-degree detection, which improves the sensitivity of the infrared sensor and can improve the use effect of the lamp.

[0024] The Fresnel lens is an arc-shaped sheet structure, which stands upright on the edge of the shell. Compared with the existing infrared sensor, which requires the sensing probe to protrude from the shell for detection, this is more convenient to assemble because there is no interference from the protruding sensing probe. At the same time, the structure of the lamp shell is simpler and the processing difficulty is relatively smaller. BRIEF DESCRIPTION OF THE DRAWINGS

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

[0055] Example 1

[0056] An infrared sensor capable of 360-degree detection, see Figure 1-Figure 3 , including a housing 100, a control component 200 and at least three sensing components 300. The control component 200 is arranged in the housing 100; the number of the sensing components 300 in this embodiment is three, and of course it can be set to other numbers, the three sensing components 300 are distributed along the circumference of the housing 100, and each sensing component 300 includes a Fresnel lens 310 and an infrared sensing probe 320, the Fresnel lens 310 is an arc-shaped sheet structure, the Fresnel lens 310 stands upright on the edge of the housing 100, the infrared sensing probe 320 is electrically connected to the control component 200, and the infrared sensing probe 320 is arranged in the housing 100 and opposite to the Fresnel lens 310.

[0057] The sensing component 300 of the infrared sensor of this embodiment specifically includes a Fresnel lens 310 and an infrared sensing probe 320. The infrared sensing probe 320 is arranged in the housing 100. The Fresnel lens 310 stands on the edge of the housing 100 and is 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 achieve detection at a larger angle, the infrared sensing probe 320 can receive infrared signals in a larger range, and its sensing angle is greatly improved on the basis of the existing range, exceeding 120°, and can reach 170° in practice. In this way, when the infrared sensor is detecting, it will not affect the sensing distance on the basis of achieving 360-degree detection, which improves the sensitivity of the infrared sensor and can improve the use effect of the lamp. The Fresnel lens 310 is an arc-shaped sheet structure, which stands upright on the edge of the shell 100. Compared with the existing infrared sensor, which requires the sensing probe to protrude from the shell 100 for detection, since there is no interference from the protruding sensing probe, assembly is more convenient. At the same time, the structure of the lamp housing is simpler and the processing difficulty is relatively smaller.

[0058] When the infrared sensor is used in a lamp, a window 611 needs to be provided on the housing of the lamp for the infrared sensor to detect. Since there are three Fresnel lenses 310 on the circumferential side of the sensor of this embodiment, correspondingly, three windows also need to be provided on the housing of the lamp, and the three windows will also occupy most of the space of the housing of the lamp, resulting in a reduction in the strength of the housing of the lamp at the position where the windows are provided, which will affect the service life of the housing of the lamp. Therefore, in order to reduce the influence of insufficient strength of the lamp caused by multiple windows, the three sensing components 300 are specifically arranged at intervals along the circumference of the housing 100, preferably arranged symmetrically, so as to avoid the problem that two of the sensing components 300 are connected or close to each other, resulting in insufficient strength at the corresponding position of the housing of the lamp. In this embodiment, the number of sensing components 300 is preferably three, which can ensure the sensitivity of the infrared sensor and the strength of the housing of the lamp using the sensor, and avoid the problem that the number of sensing components 300 is large, and the sensing housing also needs to be provided with more windows, which ultimately reduces the strength of the housing of the lamp.

[0059] In this embodiment, see Figure 3The housing 100 is provided with a partition 130 to divide the inner cavity of the housing 100 into a receiving chamber 140 and a focus chamber 150. The receiving chamber 140 is located in the partition 130, and the focus chamber 150 is located between the partition 130 and the Fresnel lens 310. The control component 200 is arranged at the upper position in the receiving chamber 140, and the infrared sensor probe 320 extends into the receiving chamber 140 and is spaced from the bottom of the receiving chamber 140. In the above structure, a storage chamber 140 located inside the partition 130 is separated by setting a partition 130, and the storage chamber 140 has good waterproof performance. The infrared sensing probe 320 is arranged in the storage chamber 140, which can provide waterproof protection for it and avoid damage caused by water; the infrared sensing probe 320 is located above the storage chamber 140 and is spaced apart from the bottom of the storage chamber 140. In this way, even if water enters the storage chamber 140, the water flows along the inner wall of the chamber to the bottom of the chamber, which will not affect the control component 200 and the infrared sensing probe 320.

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

[0061] In order to make the infrared sensor probe 320 have a larger field of view, the first avoidance opening 131 close to the opening of the Fresnel lens 310 is a gradually enlarged trumpet opening 132 .

[0062] When water enters the receiving chamber 140 and the focus cavity 150 through the assembly gap of the housing 100, in order to prevent the electronic components from being damaged by water accumulation, see Figure 3-Figure 4 The bottom of the storage chamber 140 and the focus chamber are provided with a first drain port 141 and a second drain port 151, respectively, and the water in the storage chamber 140 and the focus chamber 150 is discharged through the corresponding drain ports. The second drain port 151 at the bottom of the focus chamber 150 cooperates with the first avoidance port 131 to improve the detection effect and the use effect. For example, in an environment with high humidity and fog, the humid air in the focus chamber 150 will absorb and scatter infrared radiation, causing the infrared signal to attenuate and reduce the detection effect. In this embodiment, since the control component 200 and the infrared sensor probe 320 are arranged in the storage chamber 140, the heat generated by them in the working state enters the focus chamber 150 through the first avoidance port 131, and then is discharged from the sensor through the second drain port 151. In this process, the humid air in the focus chamber 150 is liquefied and the gas humidity is reduced, which greatly alleviates the influence of humid air on the infrared detection effect. The liquefied water can be discharged through the second drain port 151, thereby avoiding the problem of water accumulation inside the sensor, which causes the water to vaporize in a high temperature environment and further affects the detection effect of the sensor.

[0063] In this embodiment, the power supply of the control component 200 and the infrared sensor probe 320 is provided by the wire 400, that is, the wire 400 is required to supply power to the infrared sensor. Therefore, the above-mentioned storage bin 140 not only serves as the first drain port 141, but also allows the wire 400 to pass through the storage bin 140 (such as Figure 5 As shown), the wire 400 is directly threaded through the first drain port 141 without opening other through holes, which has a simple structure and simplifies the shell processing process. In addition, the wire 400 threading channel is set at the bottom of the accommodating chamber 140, which can avoid the problem of external water entering the chamber body and damaging electronic components compared to setting it on the side wall or the top.

[0064] The wiring position of the control component 200 is opposite to the position of the first drain port 141 , which facilitates the arrangement of the wire 400 .

[0065] In this embodiment, see Figure 3 The housing 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 both pass through the upper and lower ends of the housing 100. The inner cavity of the wire-passing column 160 is a wire-passing channel 161. In this way, for some lamps whose power source or light source is above the infrared sensor, the wire 400 can pass through the wire-passing channel 161 upwards after passing through the first drain port 141 to be connected to the power source or light source (such as Figure 6 The inner cavity of the connecting column 170 is used to assist the infrared sensor in connecting to the lamp. Specifically, in this embodiment, the inner side wall of the connecting inner cavity 171 of the connecting column 170 is a stepped surface that is wide at the top and narrow at the bottom. The infrared sensor can be fixed to the lamp by screws.

[0066] Among them, since the wire channel 161 of the wire post 160 is used to pass the wire 400, in order to prevent water from flowing into the wire channel 161 and causing leakage of the wire 400, the wire post 160 in this embodiment protrudes from the top surface of the shell 100 to form a boss 162, so that water on the top surface of the infrared sensor shell 100 will not flow into the wire channel 161, ensuring safe use.

[0067] Among them, the top surface of the connecting column 170 is flush with the top surface of the shell 100. In this way, the hollow connecting column 170 can not only fix the infrared sensor to the lamp, but also when there is water accumulated on the top surface of the infrared sensor shell 100, the water flows into the inner cavity of the connecting column 170 and flows out through the gap between the screw and the inner wall of the cavity.

[0068] In this embodiment, the housing 100 includes a housing body 110 and an upper cover 120. Figure 4 , Figure 7The shell body 110 is provided with a plurality of lower baffles 111 and a plurality of positioning posts 112, and the upper cover 120 is provided with a plurality of upper baffles 121 and a plurality of positioning holes 122. During assembly, the upper cover 120 is fixed to the shell body 110 through the interference fit between the positioning posts 112 and the positioning holes 122. After assembly, the upper baffles 121 cooperate with the corresponding lower baffles 111 to form the above-mentioned baffles, and form the above-mentioned accommodation chamber 140 and the focus cavity 150. A U-shaped notch 113 is provided at a position on the circumference of the shell body 110 opposite to the first avoidance opening 131, and a U-shaped groove 114 is provided at the U-shaped notch 113. A strip groove 123 is provided at a position on the bottom of the upper cover 120 opposite to the U-shaped notch 113. When assembling the Fresnel lens 310, the Fresnel lens is first clamped in the U-shaped groove 114, and after the upper cover 120 is fixed on the shell body 110, the strip groove 123 of the upper cover 120 clamps the top of the Fresnel lens, thereby fixing the Fresnel lens 310 on the shell 100. 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. When the Fresnel lens 310 is installed, 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 an upper hollow column 124. After the shell body 110 and the upper cover 120 are assembled, the lower hollow column 116 and the corresponding upper hollow column 124 are connected to form the above-mentioned wire column 160 and the connecting column 170.

[0069] In this embodiment, see 9, the control component 200 includes a main board 210, at least three probe substrates 220 electrically connected to the main board 210, and at least one adjustment substrate 230. Specifically, there are three probe substrates 220 in this embodiment, and each probe substrate 220 is electrically connected to an infrared sensing probe 320. An adjustment member 231 is electrically connected to the adjustment substrate 230, and the adjustment member 231 is specifically an adjustable resistor. The infrared sensor also includes an adjustment handle 500, and the adjustment handle 500 can pass through the housing to apply a force to the adjustment hole of the adjustable resistor so as to adjust the use parameters of the infrared sensor. For example, the adjustment handle 500 is a knob handle, and turning the knob handle can adjust the sensitivity parameters of the sensor, or adjust the brightness and light-on time of the lamp using the sensor. This is a prior art and will not be repeated here.

[0070] Among them, the main board 210 is provided with a second avoidance hole 211 and a third avoidance hole 212 for avoiding the wire column 160 and the connecting column 170. In this way, when installing the main board 210, the main board 210 is sleeved on the wire column 160 and the connecting column 170 through the second avoidance hole 211 and the third avoidance hole 212, and the main board 210 is placed on the positioning column 112 through its through hole. When the upper cover 120 is closed, the upper cover 120 presses the main board 210, thereby fixing the main board 210 in the shell 100.

[0071] Among them, the wire-passing column 160 is located at the center of the shell 100, and the connecting column 170 is located on the side of the wire-passing column 160 close to the adjustment handle 500. In this way, the wire-passing column 160 can pass through the center of the main board 210 and be limited from the center of the main board 210, which can improve the assembly stability and reliability of the main board 210. When assembling or using the adjustment handle 500, after the user applies force to the adjustment handle 500, the adjustment handle 500 will push the adjustment substrate 230, which will cause the adjustment substrate 230 to shift and will also affect the connection reliability between the adjustment substrate 230 and the main board 210 and the performance of the main board 210. For this reason, the connecting column 170 is arranged at a position close to the adjustment handle 500. When the adjustment handle 500 applies force, it is further limited by the connecting column 170, which can reduce the influence of the adjustment handle 500 on the main board 210 and improve the assembly reliability; a limit block 117 is provided at the bottom of the accommodating chamber 140, and the limit block 117 is arranged on the rear side of the adjustment substrate 230 and abuts against it, which can prevent the adjustment substrate 230 from shifting backwards.

[0072] In this embodiment, a “THISSIDE UP” mark 125 is provided on the top surface of the upper cover 120 for easy identification.

[0073] In this embodiment, LED indicator lights 250 may be provided on the three probe substrates 220 according to actual assembly requirements. When the function is adjusted or human activity is sensed, the LED indicator lights 250 will flash accordingly. Photosensitive tubes 260 are also provided to control the start-up of the lamp. During the day or when the ambient light is sufficient, the light will not turn on even if someone enters the detection range, thereby achieving energy-saving effect.

[0074] Example 2

[0075] An infrared sensor capable of 360-degree detection, the structure of the infrared sensor is substantially the same as that of the embodiment 1, except that: in the embodiment 1, there are two adjustment handles 500, the two adjustment handles 500 are arranged in the vertical direction and are located between the two Nefer lenses. Figure 10-12 There are three adjustment handles 500 and three adjustment substrates 230 . One adjustment handle 500 cooperates with one adjustment substrate 230 to perform control. Each adjustment handle 500 is disposed between two adjacent sensing components 300 .

[0076] In addition, in Embodiment 1 and Embodiment 2, the infrared sensor and the use parameters of the infrared sensor are adjusted by the adjustment handle 500. In this embodiment, the sensor may not be provided with the adjustment handle 500, and a wireless communication module 240 may be provided in the sensor to wirelessly communicate with the infrared sensor. For example, if the wireless communication module 240 is an IR receiving tube, the sensor can be set through a remote control to set the function of the lamp; or it can be an existing conventional wireless communication module such as a Bluetooth or WIFI module, so that the sensor parameters and the brightness, lighting duration, etc. of the lamp using the sensor can be controlled through the terminal device.

[0077] Example 3

[0078] An outdoor lighting fixture 600, such as Fig.13 As shown, the lamp 600 is a multi-head lamp. Figure 13-Figure 15 As shown, it includes a lamp body 610, an infrared sensor and a fastener 620, wherein the infrared sensor adopts the infrared sensor of Example 1, and the fastener 620 is a screw, which passes through the inner cavity of the connecting column 170 of the shell 100 and is threadedly connected to the lamp body, so that the infrared sensor is fixed to the lamp body 610 through the fastener.

[0079] in, Fig.13 Only one type of outdoor lamp is shown. Of course, outdoor 600 can also be used as follows Fig.16 Pillar lights.

[0080] Alternatively, depending on the different covers of the infrared sensor, the infrared sensor can also be applied to lamps with other appearances.
