Description

Technical Field

[0001] The utility model belongs to the field of navigation lights, and in particular relates to a navigation light. Background Art

[0002] However, in recent years, due to the increasing functional requirements of navigation lights, there is an urgent need to configure various parameters of the products on site. What's more, it is necessary to complete difficult operations such as upgrading the firmware of the internal driver board of the lights. At present, we can only replace the original intact lights one by one with a batch of newly configured lights after the night flight is stopped. Damage is inevitable in the process, and the removed lights must be returned to the factory, unpacked, upgraded, assembled, and leak-checked before they can be reused as usable old products, which is very costly. The reason is that the heavy aluminum shell of the lamp that cannot be opened has caused great trouble to the above adjustment and upgrade operations.

[0003] To deal with this situation, it is very necessary to upgrade the configuration of the lamp without opening the cover or even disassembling it in situ, which requires establishing communication with the lamp. The traditional solution for data connection without opening the cover is nothing more than adding contact connectors to the shell or using electromagnetic coupling coils or wireless radio frequency carriers to transmit information. However, due to the excellent shielding properties of the aluminum shell, electromagnetic waves are difficult to penetrate. Setting contacts on the aluminum shell with good conductivity has to introduce insulating materials with weak mechanical strength, which brings risks such as water leakage. Utility Model Content

[0021] Among them, there are lamp 1, upper cover 1a, notch 1a1, transparent window 1a2, base 1b, cavity 1c, prism 1d, light source 1e, reflector 1f, communication device 2, card protrusion 2a, handle 2b, light-transmitting sheet 2c, and external wire 2d. DETAILED DESCRIPTION

[0022] like Figure 1-4As shown, the lamp 1 of this embodiment includes a base 1b and an upper cover 1a. The upper cover 1a is placed on the base 1b, and a cavity 1c is provided between the upper cover 1a and the base 1b. In this embodiment, a base groove is provided at the upper part of the base 1b, and an upper cover groove is provided at the lower part of the upper cover 1a. The base groove and the upper cover groove together constitute the cavity 1c. In other embodiments, the cavity 1c can also be formed by the base groove or the upper cover groove unilaterally. A prism 1d, a light source 1e, a reflector 1f, a drive module, a control module, and a first infrared receiver are provided in the cavity 1c.

[0023] A transparent window 1a2 is provided on the upper surface of the upper cover 1a, and a prism 1d is provided at the transparent window 1a2. The reflector 1f reflects the light emitted by the light source 1e and transmits it through the prism 1d. The light source 1e in this embodiment adopts an LED lamp, and the driving module drives the light source 1e. The first infrared emitter and the driving module are both connected to the control module.

[0024] The first infrared receiver receives the infrared signal transmitted through the transparent window 1a2. This embodiment uses the transparent window 1a2 structure of the lamp 1 to add the first infrared receiver, thereby solving the technical problem that the shielding characteristics of the aluminum shell of the lamp 1 make it difficult for electromagnetic waves to penetrate.

[0025] Furthermore, the present embodiment further provides a first infrared emitter, which is also connected to the control module. The first infrared emitter is provided in the cavity 1c, and sends infrared signals to the outside through the transparent window 1a2, thereby realizing two-way communication between the lamp 1 and the outside.

[0026] In this embodiment, two dustpan-shaped notches 1a1 are provided on the upper surface of the upper cover 1a, the two notches 1a1 are symmetrical, and the transparent window 1a2 is provided at the bottom of the notches 1a1. In other embodiments, the upper surface of the upper cover 1a can also be provided with one or more than two notches 1a1.

[0027] In this embodiment, the first infrared transmitter and the first infrared receiver are arranged near the light source 1e and are respectively arranged on both sides of the transparent window 1a2. Like the light source 1e, the first infrared transmitter and the first infrared receiver also transmit and receive external infrared signals through the reflective plate 1f. In other embodiments, the first infrared transmitter and the first infrared receiver may also transmit and receive infrared signals directly without using the reflective plate 1f.

[0028] Furthermore, the present embodiment further comprises a communication device 2. A locking protrusion 2a corresponding to the shape of the notch 1a1 is provided at the lower portion of the communication device 2. In the present embodiment, since two notches 1a1 are provided, only two locking protrusions 2a are provided, and the locking protrusions 2a are locked on the notches 1a1. The locking protrusions 2a shield the transparent window 1a2. When the communication device 2 communicates with the lamp 1, the locking protrusions 2a can well ensure that external light does not easily enter the transparent window 1a2.

[0029] In this embodiment, the clamping protrusion 2a is provided with a window corresponding to the shape and position of the transparent window 1a2. After the clamping protrusion 2a is clamped on the notch 1a1, the window is just opposite to the transparent window 1a2. In this embodiment, the window is parallel to the transparent window 1a2 but the distance between them is very small, and the window is also provided with a light-transmitting sheet 2c. In other embodiments, the light-transmitting sheet 2c may not be provided, and the transparent window 1a2 and the window may also fit each other, or even no window may be provided.

[0030] Since the lamp 1 of the present embodiment is a navigation lamp, used in an airport, the navigation lamps at the airport are often densely distributed in hundreds or thousands, and the light paths between the lamps 1 often overlap each other. Each lamp 1 of the present embodiment is provided with a first infrared transmitter and a first infrared receiver, and the projection 2a of the communication device 2 is used to block the transparent window 1a2, so that external light cannot enter the navigation lamp 1 to be communicated, so that it is not affected by the light of other lamps 1, and the brightness near the window is reduced, thereby reducing the communication noise.

[0031] In this embodiment, a second infrared receiver and a second infrared transmitter corresponding to the first infrared transmitter and the first infrared receiver are provided in the window. When communication with the lamp 1 is required, the communication device 2 only needs to be placed on the lamp 1, and the protrusion 2a is locked in the notch 1a1. Since the protrusion 2a and the notch 1a1 have corresponding shapes and positions, after the protrusion 2a and the notch 1a1 are matched, the signal lines of the first infrared transmitter and the second infrared receiver can be aligned, and the signal lines of the first infrared receiver and the second infrared transmitter can be aligned.

[0032] The infrared signal emitted by the second infrared transmitter passes through the prism 1d, and then is reflected by the reflector 1f and received by the first infrared receiver. The first infrared transmitter is reflected by the reflector 1f, and then is received by the second infrared receiver after passing through the prism 1d. When the first infrared receiver receives the communication request of the second infrared transmitter, the first infrared transmitter will send a feedback request to the second infrared receiver, so that the response of the lamp 1 can be known. Similarly, the first infrared transmitter can also receive the feedback request of the second infrared transmitter, realizing two-way communication between the communication device 2 and the lamp 1.

[0033] However, due to the existence of prism 1d, the request sent by the first infrared transmitter may be reflected to the first infrared receiver after passing through prism 1d, that is, the request is also sent to the first infrared receiver, causing interference. Similarly, the second infrared transmitter may also be affected by the reflection of prism 1d and send a request to the second infrared receiver, causing signal interference. Therefore, the docking position of the first infrared receiver and the second infrared transmitter, as well as the docking position of the first infrared transmitter and the second infrared transmitter are particularly important.

[0034] In this embodiment, the locking structure of the locking protrusion 2a and the notch 1a1 can achieve fast and accurate alignment, which can well ensure the docking accuracy of the first infrared receiver and the second infrared transmitter, and the first infrared transmitter and the second infrared receiver after locking, thereby reducing the influence of the prism 1d.

[0035] In this embodiment, the first infrared transmitter and the first infrared receiver are respectively arranged on both sides of the transparent window 1a2, which also maximizes the distance between the first infrared transmitter and the first infrared receiver. In this embodiment, the second infrared transmitter and the second infrared receiver are arranged on the card protrusion 2a, and the card protrusion 2a is closest to the transparent window 1a2, so that the distance between the second infrared transmitter and the second infrared receiver and the reflective plate 1f can be minimized. Close to each other and far apart, this series of structural settings are all for reducing or even avoiding mutual interference between the two groups of infrared devices.

[0036] In this embodiment, infrared communication technology is used to realize fast and accurate two-way communication with a single lamp 1 among a large number of lamps 1, and the communication signal is good and not affected by the external environment.

[0037] Preferably, in this embodiment, a handle 2b is further provided on the upper portion of the communication device 2, and the handle 2b is very convenient to use whether it is stuck or separated.

[0038] Preferably, in this embodiment, the first infrared receiver and the second infrared receiver are provided with a filter circuit, and the filter circuit filters out unnecessary frequency waveforms. The first infrared transmitter and the second infrared transmitter are provided with a carrier oscillation circuit.

[0039] Preferably, the communication device 2 is provided with an external connection 2d, and the external connection 2d is used for an external terminal, such as an external PC, a mobile phone, etc., and can be controlled through the external terminal.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
