End caps 15 may be provided at both ends of the shell 11 to seal the two ends of the paper tube. The paper tube shown in the figure is about 1 meter long, with a rectangular cross section, a side length of 40 to 80 mm, and a wall thickness of about 3 mm. The paper tube can be formed by winding kraft paper or cardboard.

[0031] The lamp shown in the figure is installed in a suspended manner, and may also include a power supply assembly 40 installed on the ceiling and a cable assembly 30 for suspending the lamp 10 on the power supply assembly 40. Of course, the power supply assembly may be omitted, and the lamp may be directly suspended from the ceiling. The cable assembly 30 in the figure includes two steel wires for mechanical connection and one cable for electrical connection. In actual use, one steel wire may be omitted, and a cable may be used for both mechanical connection and electrical connection. Figure 2 shown.

[0032] See also Figure 2 , a light source assembly 20 is installed in the housing 11. The cable assembly 30 includes a cable 35 and a connector 31, which supplies power to the light source assembly 20 through a hole in the housing 11. When the cable and the connector are connected in place, the connector 31 can be fastened to the cable 35 with a fastener 33. After removing the connector, the light source assembly 20 can be easily pulled out of the housing 11. Figure 3 to Figure 5 A plurality of spacers 213 are provided on one side of the light source assembly 20 to maintain the spacing between the light source assembly 20 and the inner wall of the housing 11 (see Figure 4 These spacers 213 may also serve as anchor points for the cable assembly 30 in the luminaire 10, providing mechanical and / or electrical connections to the luminaire.

[0033] Figure 2 to Figure 5 The light source assembly 20 includes a metal bracket 21 bent into an arch shape and a strip-shaped light source board 25. A plurality of LED chips are mounted on the light source board 25 to provide illumination light. The reflector 23 is made of a highly reflective sheet material bent into an arch shape. In the illustrated embodiment, a plurality of inwardly bent buckles 211 are provided on the top surface of the metal bracket 21, openings 251 are provided at corresponding positions of the light source board 25, and openings 231 are provided at corresponding positions of the reflector 23. Through these openings, the buckles 211 press the light source board 25 and the reflector 23 against the inner wall of the metal bracket 21.

[0034] In order to improve the uniformity of light output, a diffuser 27 is installed at the bottom edge of the metal bracket 21 of this embodiment. The diffuser 27 is made of sheet optical plastic, with scattering particles mixed inside, or scattering texture pressed on the surface, or a combination of the two. Several hooks are provided on the bottom edge of the arched metal bracket 21 to buckle and fix the diffuser 27. When the light source assembly 20 is inserted into the housing 11, the diffuser 27 covers the light output window 12.

[0035] Another embodiment of the present disclosure is shown in Figure 6 to Figure 11 As shown. The difference from the previous embodiment is that the light source assembly 20 is integrated on the paper tube bracket 71. The paper tube bracket 71 can be inserted into the housing 11 and leave sufficient gaps 24 and 26 above and below it (see Figure 8 ).

[0036] In this embodiment, the reflector 23 and the strip-shaped light source plate 25 are inserted into the inner cavity of the paper tube bracket 71 and fixed to the inner wall of the paper tube bracket 71 by screws, for example. Figure 7 and Figure 8 The plurality of spacers 213 disposed on the outer wall of the paper tube support 71 maintain a gap 24 between the paper tube support 71 and the inner wall of the housing 11. The driver 29 can be accommodated in this gap. Fig. 9The driver 29 is a circuit board fixed to the outside of the paper tube support 71 near one end and connected to the light source board 25 through the wiring 28. Fig.10 , the paper tube support 71 also has a second light exit window 72 on one side, facing the light source board 25. When the paper tube support 71 is inserted into the housing 11, the second light exit window 72 is at least roughly aligned with the light exit window 12 of the housing 11. The so-called "roughly aligned" means that at least 90% of the area of ​​the two light exit windows overlap, so that the influence of the illumination light exiting due to the misalignment of the windows is minimized. Fig.11 As shown, a diffuser 27 can be arranged in the gap 26 between the two light exit windows to shield the light exit windows and make the exiting light uniform.
