Line a part is pierced by from 44 gap of bubble and projects from the injection side of support column 42 to diffuser plate 30, and another part reflexes to another
On bubble 44, occur to be totally reflected and reflect again in support column ontology 43 and 44 critical surface of bubble, the reflectivity in this time is r2
=1- (1-r)2.Multiple bubbles 44 later repeat the above steps, and after N layers of bubble 44, the total reflectivity of light is R=1-
(1-r)N, r < 1, when number N is sufficiently large, R is close to 100%.Further, it due to the presence of bubble 44, destroys original
Optical path, the second light pass through multiple total reflection and refraction, are irradiated to support column 42 and inject side and inject side injection from support column 42
To diffuser plate 30.
The present embodiment down straight aphototropism mode set in support column 42 by being arranged multiple bubbles 44, the light that lamp bar 20 is issued
Line projects the light for avoiding and being injected inside support column 42 to diffuser plate 30 from the injection of support column 42 side close to 100% and is supported
Column 42 absorbs, and reduces luminous energy loss, improves the efficiency of light energy utilization, while avoiding the light injected inside support column 42 and passing through
The direction of propagation after support column 42 along light shifts, so that fundamentally solving on light uniform irradiation to diffuser plate 30
There is the problem of shadow in down straight aphototropism mode set.
In the present embodiment, support column 42 include the first cylinder 421 and the second cylinder 422, the first end of the first cylinder 421 with
