According to the figure, it is a circuit diagram of white LED drive composed by the MAX1554. It is the white LED drive circuit whichis supplied by 2 to 4 section batteries, the brightness's maximum will keep constant. The Rl is a current examination resistance, its resistivity is 27 Ω, therefore LED current is about 10 mA. For enlarging current, the L1 needs to adopt a saturated density of magnetic flux higher inductance.
