In arranging fluorescent material glue-line in the front of light emitting diode, it is respectively provided with reflective glue-line in four sides of light emitting diode.
Fluorescent material glue-line is provided with the utility model exiting surface, the utility model device goes out optic component phase with five faces
Higher than, product light efficiency, go out that light directive property is strong, compared with this structure goes out optical diode with five faces, light efficiency is high, go out light directive property
By force, greatly open up product applications, improve flexibility during use.
Further, reflective glue-line described in the utility model is closer to the thickness of thin in front in the thickness close to bottom surface.Should
Design firstly reduce the cost that reflective glue consumption reduces the utility model device, makes product have more preferable competitive advantage；Its
The secondary law of refraction according to light, this design can improve the light emission rate of the utility model device, thus lifting brightness, reducing section
Temperature, increases the service life；3rd reduces the utility model device volume, weight, beneficial to application unit area endoparticle number
Lifting and Weight control；When 4th the utility model device application is the luminous curved surface of outwardly convex, this kind of it is designed to
Effectively reduce space between particle, improve brightness uniformity, lift visual comfort.
