The included angle between the extension surface of the first reflector 21 and the extension surface of the second reflector 22 and the plane where the light source is located is 45 degrees, as shown in fig. 3, the light is reflected by the first reflector 21 and then turns 90 degrees to be emitted to the second reflector 22, and then is reflected by the second reflector 22, and the turned 90 degrees is emitted towards the direction of the light source (the direction opposite to the light emitted by the light source) (the emergent light and the light source are located at the same side of the reflector). Only one circle of light rays reflected by the second reflector 22 can be seen in the front, and because each tunnel type light emitting structure can only see one circle of light rays reflected by the second reflector 22, when at least two layers of tunnel type light emitting structures which are concentrically arranged are arranged, a three-dimensional tunnel effect can be embodied. When all tunnel type light emitting structures are located in the same plane and are not arranged in a ladder shape, in order to enhance the deep feeling, a low-power light source can be selected for the tunnel type light emitting structures on the inner layer, the power of the light source is sequentially increased from inside to outside, so that light reflected by the second reflector 22 on the innermost layer is weakest, the light intensity is sequentially increased from inside to outside, the deep three-dimensional tunnel effect is realized, and the lamp housing is suitable for the condition that the inner space of the lamp housing is small.
