As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-3, a novel down lamp based on DOB light source, including a section of thick bamboo lamp body 1, mounting box 2, DOB light source circuit board 3 and expand

light subassembly

4, 1 lateral part cross-section of a section of thick bamboo lamp body is the echelonment, the diameter of a section of thick bamboo lamp body 1 is increased progressively to open end 12 by closed end 11, closed end 11 can dismantle and be connected with mounting box 2, be provided with on the closed end 11 with the through-hole 111 of mounting box 2 intercommunication, DOB light source circuit board 3 aims at through-hole 111 and installs in mounting box 2, it installs to expand light subassembly 4 in a section of thick bamboo lamp body 1. Specifically, in this embodiment, the side portion of the tubular lamp housing 1 is set to be of the stepped structure, so that when the light diffusion assembly 4 is installed in the tubular lamp housing 1, the light diffusion assembly and the tubular lamp housing 1 cannot be completely attached to each other, and a gap exists between the stepped structure of the side portion of the tubular lamp housing 1 and the light diffusion assembly 4, so that the heat dissipation effect of the tubular lamp housing 1 is improved.
