<p>PROBLEM TO BE SOLVED: To provide a technique for applying pulse beams without requiring any movable sections in a light source for gas analyzers (NDIR) due to infrared rays and rays, and specifically in a light source for gas analyzers for pulsively applying light to a cell where a sample gas is supplied. SOLUTION: The light source for gas analyzers for pulsively applying light to a cell 31 where a sample gas is supplied comprises a transformer (h) having primary coil winding 6 connected to an AC power supply P, and secondary coil winding 5 connected to an electrical heating element 1, and a heat radiation means B for dissipating heat being generated by an emission means 1. The emission means B is composed of the secondary coil winding 5 where a pair of electrode sections 1a, 1a of the electrical heating element 1 is directly connected to a pair of terminal sections 5t, 5t while they correspond each other.</p> |
