Description

Technical Field

[0001] The utility model relates to the technical field of lighting equipment, in particular to an adjustable RGB color-changing waterproof linear lamp. Background Art

[0002] A linear lamp is a flexible decorative lamp with a linear shape, often installed on buildings and billboards for outlining light lines and can also be used for local lighting. The structure of the existing linear lamp, such as an embedded linear lamp disclosed in Chinese Patent Publication No. CN217635279U, includes: a lamp base with an installation groove on it; a light source disposed in the installation groove; and a lamp cover plate covering the installation groove. Among them, there are outwardly extending baffles around the port of the installation groove of the lamp base, and spring clamps are provided at both ends of the lamp base along its length direction. The spring clamps are torsion springs, and the two ends of the torsion spring are connected end to end to form a chuck. The torsion force of the torsion spring drives the chuck to approach the side end of the lamp base and press tightly against the side end, and the chuck extends downward out of the side end of the lamp base. When the spring clamps are arranged at both ends of the lamp base along its length direction, the rapid installation of the lamp can be realized.

[0003] The lamp cover plate of the above-mentioned embedded linear lamp can only have ordinary waterproof performance. In other words, its lamp cover plate can only play a role in preventing ordinary water splashing. When installed outdoors, the situation of continuous water immersion needs to be considered. Obviously, the waterproof performance of this embedded linear lamp is insufficient. If water enters the installation groove, it is easy to cause a short circuit in the circuit and even cause electric shock to nearby personnel. Summary of the Utility Model

[0004] Therefore, in view of the above problems, the utility model proposes an adjustable RGB color-changing waterproof linear lamp, which can prevent water from entering under continuous water immersion when the negative pressure cavity is well sealed, and can cut off the power supply in time if it is recognized that the negative pressure cavity is damaged to prevent short circuit.

[0005] To achieve the above object, the utility model adopts the following technical solutions:

[0006] An adjustable RGB color-changing waterproof linear lamp includes a flexible lamp base, an RGB color-changing light strip, a flexible light-transmitting strip, a barometric pressure sensor, a light strip connecting wire, a signal connecting wire, and a controller;

[0007] A lamp slot for installing the RGB color-changing light strip and the barometric pressure sensor is formed on the flexible lamp base. The light strip connecting wire passes through the flexible lamp base and is electrically connected to the RGB color-changing light strip. The signal connecting wire passes through the flexible lamp base and is electrically connected to the barometric pressure sensor. In a negative pressure environment, the flexible light-transmitting strip is hermetically bonded to the notch of the lamp slot, so that a negative pressure cavity is formed between the lamp slot and the flexible light-transmitting strip. The RGB color-changing light strip and the barometric pressure sensor are located in the negative pressure cavity;

[0008] The controller includes an AC-DC converter, a relay switch, a dimming circuit, a wireless communication module, and a processor;

[0009] The AC input terminal of the AC-DC converter is electrically connected to the mains power supply. The DC output terminal of the AC-DC converter is sequentially electrically connected to an RGB magic light strip through a relay switch, a dimming circuit, and a light strip connecting wire to form a conductive loop. The DC output terminal of the AC-DC converter is also electrically connected to the power supply terminal of the processor. The output terminal of the processor is electrically connected to the control terminal of the relay switch. The communication port of the processor is electrically connected to a pressure sensor through a signal connecting wire. The communication port of the processor is also electrically connected to the wireless communication module.

[0010] Further, neither the RGB magic light strip nor the pressure sensor is in contact with the flexible light-transmitting strip.

[0011] Further, the controller further includes a buzzer; the buzzer is electrically connected to the output terminal of the processor.

[0012] Further, the air pressure in the negative pressure chamber is 0.6 to 0.8 standard atmospheric pressures.

[0013] Further, the wireless communication module adopts a Bluetooth communication module or a WiFi communication module.

[0014] By adopting the foregoing technical solutions, the beneficial effects of the present utility model are as follows:

[0015] When the negative pressure chamber of this adjustable RGB magic waterproof linear lamp has good airtightness, it can be continuously immersed in water without water ingress. A pressure sensor is provided in the negative pressure chamber. When the negative pressure chamber is damaged in airtightness, the pressure sensor detects the gas change (after the negative pressure chamber is damaged in airtightness, the air pressure in the negative pressure chamber changes from 0.6 to 0.8 standard atmospheric pressures to the standard atmospheric pressure). The processor controls the relay switch to disconnect and cut off the power supply to prevent short circuits from occurring, and the processor controls the buzzer to emit a prompt sound to remind the user to perform maintenance in a timely manner. This adjustable RGB magic waterproof linear lamp has higher safety and is practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In this specific embodiment, preferably, the flexible lamp base 1 is made of light-impermeable silicone material, and the flexible light-transmitting strip 2 is made of light-transmitting silicone material. The above-mentioned flexible lamp base 1, flexible light-transmitting strip 2, RGB color-changing lamp strip 3, lamp strip connecting wire 31, barometric pressure sensor 4, and signal connecting wire 41 are all existing materials, and will not be elaborated here in detail.

[0022] A lamp groove 11 for installing the RGB color-changing lamp strip 3 and the barometric pressure sensor 4 is formed on the flexible lamp base 1.

[0023] The lamp strip connecting wire 31 passes through the flexible lamp base 1 and is electrically connected to the RGB color-changing lamp strip 3, and the position where the lamp strip connecting wire 31 contacts the flexible lamp base 1 is sealed with sealant to play a waterproof role.

[0024] The signal connecting wire 41 passes through the flexible lamp base 1 and is electrically connected to the barometric pressure sensor 4, and the position where the signal connecting wire 41 contacts the flexible lamp base 1 is sealed with sealant to play a waterproof role.

[0025] In a negative pressure environment, the flexible light-transmitting strip 2 is hermetically bonded to the notch of the lamp groove 11, so that a negative pressure cavity (not marked in the figure) is formed between the lamp groove 11 and the flexible light-transmitting strip 2, and the air pressure in the negative pressure cavity is 0.6 standard atmospheric pressures - 0.8 standard atmospheric pressures. The RGB color-changing lamp strip 3 and the barometric pressure sensor 4 are located in the negative pressure cavity.

[0026] During setting, it should also be noted that neither the RGB color-changing lamp strip 3 nor the barometric pressure sensor 4 contacts the flexible light-transmitting strip 2.

[0027] The controller 5 includes a processor 51, an AC-DC converter 52, a relay switch 53, a dimming circuit 54, a buzzer 55, and a wireless communication module 56. Preferably, in this specific embodiment, the processor 51 uses an ESP32-S3 chip. The wireless communication module 56 uses a Bluetooth communication module. The AC-DC converter 52 is used to convert mains power into direct current power supply. The relay switch 53 uses a normally closed relay switch.

[0029] The AC input terminal of the AC-DC converter 52 is electrically connected to the mains power. The DC output terminal of the AC-DC converter 52 is sequentially electrically connected to the RGB magic light strip 3 through the relay switch 53, the dimming circuit 54, and the light strip connection wire 31 to form a conductive loop. The output terminal of the processor 51 is electrically connected to the control terminal of the relay switch 53. When the relay switch 53 is controlled to conduct, the RGB magic light strip 3 lights up. When the relay switch 53 is disconnected, the RGB magic light strip 3 goes out.

[0030] The DC output terminal of the AC-DC converter 52 is also electrically connected to the power supply terminal of the processor 51 to supply power to the processor 51.

[0031] The communication port of the processor 51 is electrically connected to the pressure sensor 4 through a signal connection wire 41. The pressure in the negative pressure chamber is detected by the pressure sensor 4 and transmitted to the processor 51. The pressure sensor 4 is arranged in the negative pressure chamber. When the seal of the negative pressure chamber is damaged, the pressure sensor 4 detects the gas change (when the seal of the negative pressure chamber is damaged, the pressure in the negative pressure chamber changes from 0.6 to 0.8 standard atmospheric pressure to the standard atmospheric pressure). The processor 51 controls the relay switch 53 to disconnect and cut off the power supply to prevent short circuit.

[0032] The buzzer 55 is electrically connected to the output terminal of the processor 51. When the seal of the negative pressure chamber is damaged, the processor 51 controls the buzzer 55 to emit a prompt sound to remind the user to perform maintenance in time.
