Although the preferred embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0037] Existing wall washer lamps use potting glue to achieve waterproofing, but the potting glue is easily affected by high temperature, ultraviolet rays and rain, causing aging, resulting in shedding and loosening, causing water vapor to penetrate into the lamp body from the aging position of the potting glue, affecting the electrical performance of the wall washer lamp. In addition, although the wall washer lamp uses the DMX (Digital Multiplex) digital dimming protocol to achieve free configuration of the lighting effect, it is impossible to adjust the power and luminous flux of the wall washer lamp according to different environmental requirements, which reduces the versatility of the wall washer lamp. In addition, after the wall washer lamp fails, DMX cannot feedback the fault information of the wall washer lamp, and the wall washer lamp needs to be disassembled to determine the fault point, which makes maintenance difficult and labor-intensive.

[0038] In view of the above problems, the embodiment of the present application provides a remotely controllable wall washer lamp, which can be remotely controlled by a controller and an RDM module, so as to facilitate the positioning and shielding of faulty lamp beads, and realize waterproofing of the wall washer lamp according to the sealing end cover 4 and the light-transmitting plate 3, so as to avoid the problem of failure of the wall washer lamp due to water seepage.

[0039] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0040] Figure 1 A schematic diagram of the overall structure of a remotely controllable wall washer lamp provided in an embodiment of the present application.

[0041] See also Figure 1 The wall washer lamp comprises a housing 1, a substrate 2, a light-transmitting plate 3 and a sealing end cover 4;

[0042] The substrate 2 is disposed in the housing 1, and a plurality of lamp beads (not shown), a controller and an RDM module are integrated on the substrate 2. The RDM module is used to feed back status information of the lamp beads, and the controller is used to control the lamp beads according to the status information;

[0043] Waterproof glue grooves 11 are provided on both inner sides of the housing 1 , and the openings of the two waterproof glue grooves 11 are arranged opposite to each other. The light-transmitting plate 3 is embedded in the waterproof glue grooves 11 , and the sealing end covers 4 are arranged at both ends of the housing 1 .

[0044] RDM (Remote Device Management) is the abbreviation of remote device management. The RDM protocol is an extended version of the DMX512-A protocol, which allows dimming consoles and other control devices to discover, configure, monitor the status and manage intermediate devices and line-end devices through a DMX512 network. The embodiment of the present application uses a controller and an RDM module to construct a wall washer with an RDM control system. It has a two-way status feedback function, can monitor the operating information of the lamp beads in real time, and the controller controls the lamp beads according to the operating information, which can meet different lighting effects.

[0045] Furthermore, in order to monitor various operating information of the wall washer lamp, the RDM module can feedback sufficient data information to the controller so that the controller can accurately control each lamp bead. The controller of the wall washer lamp includes a microprocessor and a monitoring module. The microprocessor is used to control the lamp bead, and the monitoring module is used to detect the status information of the lamp bead.

[0046] Further, the microprocessor is based on the DMX512 protocol.

[0047] Specifically, the wall washer with the Dmx512 protocol receives data after receiving the signal. After receiving three 3-byte messages, it determines whether the message is a DMX512 message or an RDM message. If it is an RDM message, it ends the reception after receiving the full length. If it is a DMX512 message, it ends the reception after receiving 513 bytes, and switches to data processing. After receiving the next break signal, it restarts the next frame reception. The processor outputs a PWM signal with a period of 10ms based on the current data information, and controls the current and voltage of the lamp beads according to the PWM signal to control the light intensity. Preferably, a communication module can also be integrated on the substrate 2 and the wall washer can be set through an external signal line.

[0048] The wall washer light is equipped with a processor, an RDM module, and a monitoring module so that the control system of the wall washer light can support the standard RDM technology standard protocol, realize the color effect of the remote control LED lamp beads, obtain the required precise color, and solve the color temperature, display index and light color consistency problems of LED lamps.

[0049] Specifically, based on the DMX512-A standard protocol, an RDM system for LED control applications is established. The control system of the wall washer has all the functions that characterize DMX512-related control applications, and integrates the functions of sending RDM control commands, receiving RDM feedback information, and displaying RDM information. It can detect the working status of LED lamps in real time through the control system, such as the current, voltage, temperature, operating time, fault error and other information of the lamps, which may include the following information:

[0050] 1. Intelligent LED wall washer system: Get the communication status of the DMX network, mainly to count the number of message structure errors.

[0051] 2. Queue and status message collection: Get the queue messages and status messages in the device.

[0052] 3. RDM information message: Get the list of RDM messages supported by the device and the manufacturer-defined RDM message definitions.

[0053] 4. Product information message: Get device information, such as RDM protocol version, manufacturer description, language settings, factory reset, etc.

[0054] 5. DMX512 setting message: DMX512 related settings.

[0055] 6. Sensor parameter message: Get the sensor type (voltage, current, temperature, etc.), measurement value, measurement range, etc.

[0056] 7. Light and power setting parameter messages: mainly include light usage time, power-on cycle, light status, control mode, etc.

[0057] 8. Display setting parameter message: for devices with display and display brightness level.

[0058] 9. Device configuration parameter messages: such as horizontal inversion, vertical inversion, horizontal / vertical swapping, and real-time clock acquisition and setting.

[0059] 10. Equipment control parameter information: including equipment identification, equipment reset, equipment self-test, working mode setting, etc.
