NOVELTY - The utility model relates to the technical field of light wave tube, specifically to a one-way conductive graphene light wave tube, comprising a transparent outer tube and graphene heating element mounted in the outer tube, two ends of the outer tube are sealed by vacuum, and two ends of the outer tube are connected with a high temperature resistant porcelain head, two ends graphene the heating element respectively pass through the two ends of the outer tube, and respectively connected with a power supply line in the high temperature resistant ceramic head of the two ends of the outer tube; one side of the outer wall of the outer pipe along the length direction is provided with a nano-ceramic high temperature resistant coating layer, the other side is set as a transparent side; the outer walls of the two high temperature resistant ceramic heads are detachably connected with a fixed bracket. The invention solves the problem in the prior art, most graphene light wave tube heat transfer direction is 360 degrees, mounting the device of the graphene light wave tube needs to increase the reflection film device for heat reflection, large area of the reflecting film is not convenient to maintain, but also improves the problem of the total cost. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a grill; (2) an oven.
