IR led strip Is the electrical energy, it Can be converted into electrical energy to near-infrared light directly (not visible),is directly converted into near infrared (not visible), it is emitting device that can radiate the infrared light, infrared led strip in the working process of the parameters are not allowed to exceed the limit value, so when using ir led strip should pay attention to the parameters , not free to replace. In addition, it can not arbitrarily change the limiting current resistor of infrared led strip.

The following is used to explain about problems of the emission intensity and emission angle:

1. Launch angle θ1/2： in the luminous (or radiant) intensity distribution graph(angular displacement), luminous (or radiant)is greater than half the maximum intensity，and form a angle. in here we need to know the following points: the same two wafers launch tube, 2θ1 / 2 more bigger, then Iv smaller.holder into colloidal deeper ,angle is larger.; There are many effects of emission angle factors that the support pipe bowl size and depth, the mould R angle size and the wafer size height etc..
