[0036] like Figure 1-3 As shown, a retro tungsten filament ambient light includes a lamp body assembly 1, a light source assembly, a bracket assembly 2, and a control module 6. The lamp body assembly 1 includes a ring lamp holder 11, a reflector 12, a front cover plate 13, and a rear cover plate 14.

[0037] The reflector 12 is disposed inside the ring lamp holder 11. The reflector 12 and the ring lamp holder 11 are connected by a front cover plate 13 and a rear cover plate 14 respectively. The inner surface of the reflector 12 has a hammer texture (not shown in the figure) and a 24K gold matte plating.

[0038] The light source assembly includes an LED chip 3, a phosphor coating covering the LED chip 3 (not shown in the figure), and a control circuit 4;

[0039] The phosphor coating is configured to output light with a color temperature of 1800K to 2000K;

[0040] The control circuit 4 is used to simulate brightness fluctuations of 0.1 to 0.3 lux;

[0042] The control module 6 is electrically connected to the control circuit 4, and the control module 6 is equipped with a DMX512 / RDM protocol decoder.

[0043] In this embodiment, the inner surface of the reflector 12 is first formed with a hand-hammered texture reminiscent of a medieval candlestick by a lost-wax casting process, and then matte-finished with a 24K gold plating layer; under the action of an LED light source, the light refraction presents a hand-hammered gold foil diffused effect reminiscent of a church dome mural.

[0044] In this embodiment, by covering the LED chip 3 with a phosphor coating that can output light with a color temperature of 1800K to 2000K, the color temperature is close to that of a tungsten filament lamp or candlestick, accurately reproducing the 589nm characteristic spectrum of a whale oil candle burning; and by controlling the circuit 4 to restore the natural fluctuation of 0.1 to 0.3 lux of a real candle flame, the visual effect of an early tungsten filament lamp or candlelight is realistically reproduced through the LED.

[0045] The above structure enables the LED light fixture to present a realistic and retro tungsten filament lamp or candlelight visual effect, which can meet the needs of theater stages, themed hotels and other scenarios.

[0046] The above structure can achieve 270° annular light domain coverage.

[0047] Furthermore, such as Figure 1-3 As shown, in order to make effective use of space and enhance the design and aesthetics of the lamps, the ring lamp holder 11 forms an installation chamber 10 with the reflector 12, the front cover plate 13 and the rear cover plate 14.

[0048] The control module 6 and the control circuit 4 are located in the installation chamber 10.

[0049] Furthermore, such as Figure 1-3 As shown, in order to improve the connection reliability and stability of LED chip 3, the lamp holder assembly 5 includes a bulb cover 51, a bulb holder 52 and a lamp holder fixing plate 53;

[0050] The LED chip 3 is located inside the bulb cover 51;

[0051] One end of the bulb holder 52 is connected to the bulb cover 51, and the other end passes through the reflector 12 to the mounting chamber 10 and is connected to the bulb holder fixing plate 53.

[0052] The lamp holder fixing plate 53 is fixedly connected to the ring lamp holder 11.

[0053] In this embodiment, a concealed wiring design is adopted, and the wire connecting the LED chip 3 extends through the through hole of the bulb holder 52 to the mounting chamber 10 and connects to the control module 6.

[0054] Furthermore, such as Figure 1-3 As shown, in order to achieve stable and adjustable beam angle of the lamp and to be suitable for various installation forms, the bracket assembly 2 includes a connecting arm 21 located outside the ring lamp holder 11, and the two ends of the connecting arm 21 are respectively connected to the ring lamp holder 11 through damping rotation connectors 2322.

[0055] The connecting arm 21 is provided with a connector 23 for external connection in the middle.

[0056] In this embodiment, the connector 23 is provided with a threaded hole, which enables the lamp to support three medieval-style installation forms: hanging, floor mounting, and wall mounting.

[0057] In this embodiment, the damping rotation connector 2322 is a conventional technology in the field and will not be described in detail here.

[0058] Furthermore, to make the lamp fixture more in line with the classic style, the connecting arm 21 is made of etched brass.

[0059] Furthermore, such as Figure 1-3 As shown, in order to improve the uniformity of the light, the LED chip 3 is located at the origin of the ring lamp holder 11.

[0060] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model patent.
