Description

Technical Field

[0001] The utility model specifically relates to the technical field of semiconductors, and more specifically, it is an intelligent guiding lamp for stair steps. Background Technique

[0002] The step guiding lamp is a lighting fixture installed on the stair steps. Usually, an LED lamp is used as the light source. Its main function is to provide clear step guidance for people at night or in insufficient light conditions to improve the safety of walking.

[0003] However, there are many types of step guiding lamps. One is in the form of a light strip. When someone walks up the stairs, the infrared induction device can quickly detect the infrared rays emitted by the human body, and then turn on the step guiding lamp. As long as a person approaches the stair steps, all such lamps will light up, and they will also work as usual during the day; over time, a large amount of energy will be consumed.

[0004] Another type is the independent type that can light up gradually as the human body moves. When this type lights up, it requires the human foot to be placed on the step to light up, resulting in only being able to see the position of the current step when going up and down the stairs, and unable to view the upper or lower stairs in advance, which is prone to the danger of stepping on air. Content of the Utility Model

[0005] The purpose of the utility model is to provide an intelligent guiding lamp for stair steps. Each step guiding lamp is installed independently, and infrared sensors are also provided at the two diagonal corners of each independent guiding lamp, which can turn on one or two levels of guiding lamps in advance, and gradually turn on in advance as the human body moves. It can not only reduce consumption but also meet the lighting requirements. To solve the technical problems raised in the above background technique.

[0008] The infrared transceiver includes a hollow shell and an end cap. The end cap is in interference fit at the end of the hollow shell. Infrared transceiver sensors and wire troughs are also diagonally arranged on the hollow shell, and a signal conversion circuit is fixed inside the hollow shell.

[0011] As a further technical solution of the present utility model, an installation plate for fixing the circuit board assembly is integrally provided on the inner side of the outer shell, and the installation plate and the circuit board assembly are connected by fasteners.

[0012] As a further technical solution of the present utility model, the LED lamp includes a rear plate for fixing the PCB board and a lamp cover covering the side of the rear plate. A locking claw is integrally provided on the side of the rear plate away from the lamp cover.

[0013] As a further technical solution of the present utility model, an infrared sensor and a photoresistor are respectively embedded in the upper and lower parts of the side of the lamp cover.

[0014] As a further technical solution of the present utility model, a card slot for fixing the LED lamp is also opened on the inner side of the outer shell, and the end of the locking claw is clamped inside the card slot.

Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-6 , an intelligent guiding lamp for stair steps provided by an embodiment of the present utility model includes an LED lamp 7 for illuminating the steps, a housing 4, and an infrared transceiver 6. The LED lamp 7 is arranged on the side of the housing 4, and the infrared transceiver 6 is movably connected to one side of the housing 4 close to the LED lamp 7;

[0029] The infrared transceiver 6 includes a hollow shell 61 and an end cap 62. The end cap 62 is in interference fit at the end of the hollow shell 61. The infrared transceiver sensors 63 and wire passing grooves 64 are diagonally arranged on the hollow shell 61, and a signal conversion circuit 65 is fixed inside the hollow shell 61.

[0030] In this embodiment, a sleeve is integrally provided at the central position of the hollow shell 61, and the sleeve is inserted and fitted on a rotating column 41 arranged inside the housing 4.

[0031] In this embodiment, the infrared transceiver sensor 63 is embedded on the side of the hollow shell 61 away from the housing 4, the wire passing groove 64 is opened on the side of the hollow shell 61 close to the housing 4, and the wire passes through the inside of the wire passing groove 64.

[0032] In this embodiment, an installation plate for fixing the circuit board assembly 5 is integrally provided on the inner side of the housing 4, and the installation plate and the circuit board assembly 5 are connected by fasteners.

[0033] In this embodiment, the LED lamp 7 includes a rear plate 71 for fixing the PCB board and a lamp cover 72 covering the side of the rear plate 71. A locking claw 74 is integrally provided on the side of the rear plate 71 away from the lamp cover 72, which facilitates the replacement of the internal LED lamp beads after the LED lamp 7 is removed.

[0034] Specifically, an infrared sensor and a photosensitive resistor 73 are respectively embedded in the upper and lower parts of the side of the lamp cover 72.

[0035] In this embodiment, a card slot for fixing the LED lamp 7 is also provided on the inner side of the housing 4, and the end of the locking claw 74 is clamped inside the card slot.

[0036] By adopting the above technical solution, when the guiding lamp on a certain step is lit, it will send a signal through the circuit board assembly 5. The signal is transmitted to the signal conversion circuit 65 for conversion, so that the signal conversion circuit 65 controls the infrared transceiver sensor 63 to send a signal to the lower and / or upper level. After the infrared transceiver sensor 63 on the guiding lamp at the upper or lower level receives the signal, the infrared transceiver sensor 63 transmits the received signal to the signal conversion circuit 65. The signal conversion circuit 65 converts the signal and then transmits it to the circuit board assembly 5 to control the guiding lamps at the upper or lower level to light up simultaneously, realizing the early illumination of the guiding lamp.

[0037] In this embodiment, a base 1 is fixed to the side of the housing 4 by fasteners, and a positioning protrusion inserted into the inner side of the housing 4 is integrally provided on the side of the base 1 close to the housing 4. The base 1 can be installed on the wall near the stairs through fasteners.

[0038] In this embodiment, a wire passing hole 2 and a groove 3 are respectively provided on the other side of the base 1, and the grooves 3 are distributed on both sides of the wire passing hole 2 to place the wires and prevent the wires from being damaged due to extrusion.

[0039] In this embodiment, the PCB on the side of the rear plate 71 is also fixed with illuminating LED lamp beads, and the LED lamp beads are electrically connected to the circuit board assembly 5.

[0040] In this embodiment, an infrared sensor is fixed on the side of the lamp cover 72. When a person passes by, the infrared sensor generates an electrical signal and sends the electrical signal into the circuit board assembly 5. The voltage stabilizing circuit inside the circuit board assembly 5 supplies power to the LED lamp beads, and at the same time sends the signal into the signal conversion circuit 65. After being converted by the signal conversion circuit 65, it controls the infrared transceiver sensor 63 to send a signal.

[0041] Specifically, the infrared transceiver sensor 63 is electrically connected to the signal conversion circuit 65, and the signal conversion circuit 65 is electrically connected to the circuit board assembly 5.

[0042] Specifically, the infrared transceiver sensor 63 transmits the received signal to the signal conversion circuit 65. The signal conversion circuit 65 converts the signal and then transmits it to the circuit board assembly 5. The circuit board assembly 5 controls the LED lamp beads on the PCB board to emit light, providing advance lighting for the stair treads.

[0043] In this embodiment, the photosensitive resistor 73 is electrically connected to the circuit board assembly 5. In the daytime when the light is good, the resistance of the photosensitive resistor 73 increases, so that the circuit board assembly 5 cannot supply power to the LED lamp beads, further saving energy.

[0044] The working principle of the present utility model is as follows: When in use, first install the base 1 on the wall near the tread through fasteners, and then install the housing 4 on the side of the base 1. According to the low inclination of the stair tread, adjust the orientation of the infrared transceiver sensor 63 on the hollow shell 61 so that the infrared transceiver sensor 63 can cooperate with the adjacent infrared transceiver sensor 63. When a person approaches the side of the lampshade 72, the infrared sensor at the end of the lampshade 72 senses the approach of the person and generates an electrical signal, and transmits the electrical signal to the circuit board assembly 5. The circuit board assembly 5 controls the LED lamp beads to emit light to illuminate the current tread. At the same time, the circuit board assembly 5 also transmits the signal to the signal conversion circuit 65. The signal conversion circuit 65 controls the infrared transceiver sensor 63 to emit an infrared signal to the guiding lamp installed on the upper-level tread. The infrared transceiver sensor 63 in the upper-level guiding lamp transmits the received signal to the signal conversion circuit 65. The signal conversion circuit 65 converts the signal and then transmits it to the circuit board assembly 5. The circuit board assembly 5 controls the LED lamp beads on the PCB board to emit light to illuminate the upper-level tread, realizing advance lighting and preventing the user from stepping on the empty space. The individually set guiding lamp can reduce energy consumption, and when the light is good in the daytime, the photosensitive resistor 73 can turn off the power supply according to the change of its own resistance value, further playing an energy-saving role;

[0045] After the person passes by, the infrared sensor on the side of the lampshade 72 stops outputting the electrical signal, and the circuit board assembly 5 no longer provides a signal for the signal conversion circuit 65. At this time, the infrared transceiver sensor 63 only receives signals and does not emit signals. When the infrared transceiver sensor 63 cannot receive signals, the circuit board assembly 5 no longer supplies power to the LED lamp beads, and the lamp beads automatically go out after the power is cut off.
