1.4-W blue laser diode boosts laser projectors
Mounted in a compact TO-56 package, the PL TB450 high-power InGaN laser diode provides a 1.4-W optical power output, making it particularly suitable for professional projectors for conference rooms and home cinemas requiring a luminous flux greater than 1,000 lm. The blue (450-nm) diode also suits other applications, from stage and decoration illumination to medical functions.
High output occurs with at room temperature with an input current of 1.2 A and efficiency of 27%. The temperature of the laser rises only slightly in use, so depending on its application, it can have a service life up to 10,000 hours at 40°C in continuous operation, The overall operating temperature range is 0° to 70°C.
