Abstract: A light-concentrating panel is disclosed. The light-concentrating panel comprises a planar light collecting element and a linear light collecting element. The planar light collecting element receives and collects the planar light, and then emits out as linear light. The linear light collecting element receives the linear light. The linear light from the planar collecting element enters the linear light collecting element by passing a planar-linear imaginary plane, which is located between the planar light collecting element and the linear light collecting element. The linear light from the planar collecting element are collected and turned into the spot light by the linear light collecting element.

Abstract: An automobile dirty smoke eliminator which mainly consists of two oval tin plates externally, and upper and lower exhaust pipes, left and right support plates, a blade, a discharge chamber, a discharge pipe, etc. internally. The principle of the present invention mainly consists in making use of the effect of mixing water and gas to entirely eliminate automobile dirty smoke. When the dirty smoke (exhaust gas) of automobile enters into the lower exhaust pipe of the present invention, the blade at the outlet of said lower exhaust pipe submerged in water is impacted by the compression force derived from the engine exhaust stroke so as to generate a mixture of said water and exhaust gas and to form a whirlpool having many buddles. The effect of walls of left and right support plates promote the toxin in the said dirty smoke (exhaust gas) automatically to deposit in the said water.
