Conventional lighting devices are generally provided with sensing means to control the switching of the lighting device, for example by means of a voice-activated switch or a light-sensitive resistor. However, the control method using the voice-operated switch or the photoresistor still has a great waste problem. For example, when a voice-operated switch is used, the lighting device is turned on to work when noise is generated around, and when a photoresistor is adopted, the lighting device is turned on to work when ambient light is dark; the problem that lighting equipment is mistakenly opened exists in the mode, the induction device cannot be adjusted according to different field conditions, and the practicability is limited to a certain degree.
Referring to fig. 1 to fig. 3, in order to solve the above technical problems, in a first aspect, the present application provides an illumination apparatus 100, which includes a housing 10, and a light source 20 and a power driver 30 mounted on the housing 10, wherein the power driver 30 is electrically connected to the light source 20 and supplies power to the light source 20 for illumination. The lighting device 100 further includes an adjusting device 40 connected to the housing 10, and a sensing device 50 disposed outside the housing 10 and connected to the adjusting device 40, wherein the adjusting device 40 is used for adjusting a position of the sensing device 50 relative to the housing 10, and the sensing device 50 is electrically connected to the power driver 30.
Wherein the adjusting device 40 adjusts the position of the sensing device 50 relative to the housing 10 includes: the adjusting device 40 adjusts the sliding motion of the sensing device 50 in a direction parallel to the plane of the housing 10, or the adjusting device 40 adjusts the movement of the sensing device 50 perpendicular or substantially perpendicular to the plane of the housing 10. Specifically, by slidably connecting the adjusting device 40 to the housing 10, the movement of the sensing device 50 connected to the adjusting device 40 is controlled by controlling the adjusting device 40 to slide on the housing 10, so as to realize the sliding of the sensing device 50 on the plane parallel to the housing 10, thereby adjusting the position of the sensing area of the sensing device 50; the adjusting device 40 is configured to be retractable or adjustable up and down, so that the sensing device 50 moves perpendicular to the plane direction of the housing 10 under the control of the adjusting device 40, thereby adjusting the sensing height of the sensing device 50, and adjusting the coverage of the sensing area of the sensing device 50, understandably, the position of the sensing device 50 is adjusted by adjusting the sliding of the sensing device 50 along the plane direction parallel to the housing 10, so as to adjust the position change of the sensing area of the sensing device 50, and the height of the sensing device 50 is adjusted by adjusting the sliding of the sensing device 50 perpendicular to the plane direction of the housing 10, so as to adjust the range change of the sensing area of the sensing device, understandably, the larger the installation position of the sensing device 50 is away from the ground, i.e., the higher the sensing height is, and the larger the sensing area of the sensing device 50 is.
In operation, the sensing end 501 of the sensing device 50 is installed towards the light emitting direction of the light source 20, so that the sensing device 50 can sense the area portion of the light emitting direction, and when sensing a corresponding signal, the sensing device 50 sends an electrical signal to enable the power driver 30 to control the light source 20 to operate and irradiate. When the sensing device 50 does not sense the corresponding signal, the sensing device 50 sends an electrical signal to enable the power driver 30 to control the light source 20 to stop operating. The sensing device 50 can adjust the position relative to the housing 10 through the adjusting device 40, so that the sensing device can be adaptively adjusted for different fields to ensure the sensing control effect of the sensing device 50. For example, when the field is dark, the sensing area needs to be enlarged, and the installation height of the sensing device 50 can be increased by controlling the adjusting device 40, so that the effect of enlarging the sensing area can be realized; or, when two lighting apparatuses 100 arranged at an interval are used simultaneously, since the distance between the two lighting apparatuses 100 is large, and a sensing blind area exists between the two lighting apparatuses 100, the installation height of the sensing device 50 can be increased by controlling the adjusting device 40, that is, the sensing area can be increased, so as to avoid the influence of the sensing blind area on the lighting effect of the lighting apparatuses 100. Meanwhile, the sensing device 50 is installed outside the housing 10 through the adjusting device 40, that is, the housing 10 does not directly contact with the sensing device 50, and a split installation manner is adopted, so that the influence of heat dissipation of the housing 10 on the normal operation of the sensing device 50 is reduced.
Specifically, the sensing device 50 may employ a microwave sensor, an infrared sensor, or the like. In one embodiment of the present embodiment, a microwave inductor is used as the induction device 50. The microwave inductor has the working principle that the microwave emitted by the emitting part of the microwave inductor is absorbed or reflected when meeting an object to be measured, so that the power is changed; if the receiving part of the microwave sensor is used for receiving the microwave which passes through the object to be detected or is reflected by the object to be detected, converting the microwave into an electric signal and processing the electric signal by the measuring circuit of the microwave sensor, the microwave detection is realized. Therefore, the sensing end 501 of the microwave sensor is installed toward the light emitting direction of the light source 20, the microwave sensor can sense the light emitting region of the light source 20, and when a person enters the sensing region, the microwave sensor controls the light source 20 to illuminate. Meanwhile, a timing module may be added to the power driver 30, so that the power driver 30 controls the light source 20 to illuminate for a certain time and then automatically turns off, thereby realizing efficient operation of the illumination apparatus 100 and reducing energy waste. Meanwhile, for different sites, when the lighting device 100 is used, the position of the microwave inductor may be adjusted by the adjusting device 40 so that the microwave inductor senses the proper position. For example, when the field requires a larger sensing range, the position of the microwave inductor can be adjusted by the adjusting device, and the distance between the microwave inductor and the ground can be adjusted to be larger, so that the sensing range of the microwave inductor is larger.
Referring to fig. 1 to 4, in an embodiment, the sensing end 501 of the sensing device 50 faces the light emitting direction of the light source 20. By directing the sensing end of the sensing device 50 to the light emitting direction of the light source 20, the sensing device 50 senses the signal in the light emitting region to control the lighting device 100 to be turned on, so that the lighting device 100 is controlled to work by the sensing device 50 when a person is near the light emitting region, and energy waste caused by unnecessary starting of the lighting device 100 is avoided.
Referring to fig. 1 to 4, in an embodiment, the adjusting device 40 includes a first adjusting bracket 401 mounted on the housing 10 and a second adjusting bracket 402 mounted on the sensing device 50, the first adjusting bracket 401 includes a first mounting portion 403, the second adjusting bracket 402 includes a second mounting portion 404, and the first mounting portion 403 is detachably connected to the second mounting portion 404.

For example, a plurality of mounting holes are provided in the first mounting portion 403 and the second mounting portion 404, respectively, or a kidney-shaped hole is provided in one of the first mounting portion 403 and the second mounting portion 404 and a mounting hole is provided in the other. In one embodiment of this embodiment, a waist-shaped hole is opened on the first adjusting bracket 401 as the first mounting portion 403, a mounting hole is correspondingly opened on the second adjusting bracket 402, the first adjusting bracket 401 and the second adjusting bracket 402 are connected, a bolt is used to respectively pass through the waist-shaped hole on the first mounting bracket and the mounting hole of the second mounting bracket, after the positions of the first adjusting bracket 401 and the second adjusting bracket 402 are adjusted, the first adjusting bracket 401 and the second adjusting bracket 402 are clamped by screwing a nut on the bolt to realize fixation.
In one embodiment, the adjustment device 40 includes a sliding adjustment member slidably mounted to the housing 10, and the sensing device 50 is connected to the housing 10 via the sliding adjustment member. The sensing device 50 is mounted on the housing 10 by means of a sliding adjuster, i.e. the sensing device 50 can slide on the housing 10 by means of the sliding adjuster to adjust the position, thereby adjusting the sensing area of the sensing device 50. In one embodiment of the present embodiment, the sliding adjusting member may be a sliding bracket slidably connected to the housing 10, and the position of the sensing device 50 relative to the housing is adjusted by sliding the sliding bracket on the housing 10.
In one embodiment, the adjustment device 40 further comprises a height adjustment member telescopically coupled to the sliding adjustment member, and the sensing device 50 is coupled to the height adjustment member. The height of the sliding adjusting member is adjusted by the height adjusting member, so that the position of the sensing device 50 connected with the height adjusting member corresponding to the housing 10 can be adjusted. The height adjusting member may adopt a first threaded pipe and a second threaded pipe which are connected in a threaded manner, the first threaded pipe is rotatably connected to the sliding support, the second threaded pipe is connected to the sensing device 50, the degree of the second threaded pipe which is rotatably connected to the first threaded pipe is adjusted by rotating the first threaded pipe, and then the height of the sensing device 50 is adjusted. Namely, the sliding adjustment of the sliding bracket on the housing 10 and the height adjustment of the first threaded pipe and the second threaded pipe are matched to adjust the position of the sensing device 50 corresponding to the housing 10, so as to perform adaptive adjustment on the sensing device 50 in different places, so as to facilitate the use of the lighting device 100.
In one embodiment, the adjustment device 40 comprises a cardan pipe connected at one end to the housing 10, the other end of the cardan pipe being connected to the induction device 50. Utilize the universal pipe to be connected with induction system 50 to control swing universal pipe can directly carry out position control, simple and convenient to induction system 50. The universal pipe can be a corrugated pipe, the length of the universal pipe can be adjusted by stretching or compressing the corrugated pipe, and the orientation of the universal pipe can be changed by twisting the corrugated pipe; the above-described gimbals may also be goosenecks, which may be optionally twisted to change the position of the attached sensing devices 50.
Referring to fig. 1, in an embodiment, the lighting apparatus 100 further includes a temperature and humidity acquisition and analysis device 60 mounted on the housing 10 and an alarm device electrically connected to the temperature and humidity acquisition and analysis device 60, wherein the temperature and humidity acquisition and analysis device 60 has a signal emitting portion. The temperature and humidity acquisition and analysis device 60 is mounted on the housing 10 to monitor the environmental data near the lighting device 100, and when the data is abnormal, an alarm can be given out through an alarm device to remind; meanwhile, the temperature and humidity acquisition and analysis device 60 has a signal transmitting part, and can transmit the monitored signals to the terminal, so that an operator can check the monitored signals conveniently, or adjust the temperature and humidity of the surrounding environment according to the monitoring data, so that the lighting equipment 100 is kept in a proper working environment, and the service life of the lighting equipment is prolonged.
Referring to fig. 1 and 5, the lighting device 100 further includes a heat dissipation structure 200 disposed on the housing 10, the heat dissipation structure 200 includes a plurality of long fins 70 disposed on the housing 10, each long fin 70 has a first inward end 701, each long fin 70 is distributed around the center of the housing 10, each first inward end 701 faces the center of the housing 10, and a distance between adjacent first inward ends 701 is not less than 6 mm. The first inward end 701 refers to an end portion close to the center of the housing 10 when the long fin 70 is disposed on the housing 10; the distance between the adjacent first inward ends 701 is a straight line distance between the end points of the two adjacent first inward ends 701 on the same height and closest to the center of the housing 10. It is understood that the first inward ends 701 are the portions of the long fins 70 closest to the center of the housing 10, and the long fins 70 are distributed around the center of the housing 10, i.e., the distance between adjacent first inward ends 701 is the minimum distance between adjacent long fins 70.
In the heat dissipation operation, the housing 10 absorbs heat dissipated by the lighting device 100 during operation, and at the same time, the housing 10 conducts the heat to each of the long fins 70, and exchanges heat with the outside air through the outer surface of each of the long fins 70 to dissipate the heat efficiently. The first inward ends 701 of the long fins 70 face the inside of the housing 10, and the long fins 70 are distributed around the center of the housing 10, so that a certain distance is formed between the long fins 70 to ensure the heat exchange efficiency between the long fins 70 and the outside air. Meanwhile, the distance between the adjacent first inward ends 701 is set to be not less than 6mm, that is, the minimum distance between the adjacent long fins 70 is controlled to be 6mm, so as to ensure the heat dissipation effect. The above-mentioned manner that each long fin 70 is distributed around the center of the housing 10 may be that the long fins 70 are distributed around the center of the housing 10 evenly, so that each long fin 70 is distributed radially and outwardly at the center of the housing 10, that is, the distance between each adjacent long fins 70 is gradually increased along the direction far from the center of the housing 10, the gap between the long fins 70 at the edge of the housing 10 is larger, the heat exchange effect between the long fins 70 and the outside air is better, and the heat dissipation effect is better. It can be understood that the distances from the first inward ends 701 of the long fins 70 to the center of the housing 10 may be the same, or may be different or partially different, as long as the distance between the adjacent first inward ends 701 is not less than 6 mm. In this embodiment, the first inward ends 701 of the long fins 70 are arranged at the same distance from the center of the housing 10, that is, the first inward ends 701 of the long fins 70 are all located on the same concentric circle of the housing 10. By controlling the arrangement of the long fins 70 and the minimum distance between the inward ends of the adjacent long fins 70, the long fins 70 have high heat dissipation efficiency and a better heat dissipation effect.
Referring to fig. 5, in an embodiment, the heat dissipation structure further includes a plurality of middle fins 80 disposed on the housing 10 and distributed around the center of the housing 10, the length of the long fins 70 is greater than the length of the middle fins 80 along the radial direction of the housing 10, and the middle fins 80 are disposed between adjacent long fins 70. The length of the long fin 70 refers to the length of the intersection of the long fin 70 and the housing 10, and similarly, the length of the middle fin 80 refers to the length of the intersection of the middle fin 80 and the housing 10. By providing the intermediate fins 80 between the adjacent long fins 70, the heat dissipation area is increased by the intermediate fins 80, thereby accelerating heat dissipation and improving the heat dissipation effect. It is understood that when the housing 10 is large enough, the adjacent middle fins 80 and the long fins 70 have a larger distance therebetween at a position far from the center of the housing 10, and at this time, the middle fins 80 may be further disposed between the adjacent middle fins 80 and the long fins 70; when the two middle fins 80 still have a larger distance from the center of the housing 10, the middle fin 80 may be further disposed between the two middle fins 80; by analogy, the long fins 70 and the sufficient middle fins 80 are arranged on the housing 10 to ensure the heat dissipation efficiency.
Referring to fig. 1 and fig. 6, in a second aspect, the present application further provides an illumination system 300, which includes a plurality of illumination apparatuses 100 as described above, each illumination apparatus 100 is sequentially arranged, and the sensing areas of the sensing devices 50 of adjacent illumination apparatuses 100 are partially overlapped. The lighting system 300 is generally used for illumination of an area, for example, when illuminating a long corridor, a plurality of lighting devices 100 are installed at intervals on the top of the corridor. In order to ensure an effective light emitting area of each lighting device, the distance between adjacent lighting devices 100 is generally set to be large enough to ensure efficient illumination of each lighting device 100. However, when the distance between adjacent lighting apparatuses 100 is too large, a blind area is generated, that is, after a person walks into the blind area, the walking lighting apparatus 100 is dark, and the next lighting apparatus 100 lacks no illumination. With the lighting device of the present application, the sensing areas of the sensing devices 50 can be adjusted to partially overlap each other, for example, the installation positions of the sensing devices are adjusted to be higher, that is, the sensing areas of the sensing devices are increased to partially overlap each other, as shown in fig. 6, when a person walks into the overlapped sensing areas, the previous lighting device 100 still works for illumination, and the next lighting device 100 also turns on for illumination, so as to avoid the influence on the use of the lighting system 300 caused by the dead zone of sensing between the adjacent lighting devices 100.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
