Laser lens direct good or good reflection?

Laser lenses are generally divided into two categories, which are commonly known as reflective and direct laser lenses. The reflective type uses a blue laser head to hit the laser on the high beam led phosphor to emit light, which enhances the high beam. There is a direct laser lens, but the so-called direct laser lens laser module also needs to be divided into two categories, one is a transmissive laser head, and the other is a reflective laser head. Transmission type laser head, is the laser emits white light through the luminous body, the volume is small, but the white laser head spot has yellow halo. Reflective laser head, is the laser head light to the molybdenum reflective lens, the laser is reflected to the phosphor, the relative volume is large, but the spot is perfect. So the laser lens direct good or reflection good? The following small series to introduce to you.
