Description
Technical field
The present invention is the related anti-dazzle structure of LED lamp tube, espespecially a kind of lamp that LED light source can be effectively prevent to cause disability glare
Manage anti-dazzle structure.
Background technique
It is various to be also popularized in city as the fluorescent tube product of light source using LED as the related application technology of LED graduallys mature
In, however since LED is essentially a point light source, if be applied in fluorescent tube product must overcome light excessively concentrate and
Caused by the dazzling characteristic of dazzle.
In No. M495466 novel case of TaiWan, China patent announcement, a kind of LED light bar is disclosed, structure is mainly wrapped
It includes: a bar shaped bracket;The side of the bar shaped bracket is arranged at least one LED chip;At least one fluorescent glue-line, each firefly
Optical cement layer is to correspond respectively to a LED chip and seal the corresponding LED chip, and the minimum point of the fluorescent glue-line is low
In the side of the bar shaped bracket.
Such structure design is that bar shaped bracket is exposed outside, and has no the lamp of tool defencive function and light transmission in peripheral side
Pipe is being applied upper and can not replace traditional fluorescent tube product, using by biggish limitation;Meanwhile utilizing fluorescent glue-line
Though the structure for sealing each LED chip suitably can be such that light uniformly spreads, it will cause the serious decaying of light, influence whole
Illumination efficiency.
Separately in TaiWan, China patent announcement the M379007th " there is the complementary LED lamp tube for expanding photo structure " novel case, take off
Reveal the structure of the circuit board being respectively set in an elongated fluorescent tube one with multiple LED and an expansion mating plate with translucency,
And the inner wall of the fluorescent tube is provided with multiple linear convex architectures, which is the lower section that the LED illumination face is arranged in,
At least it is provided with the lines of several protrusions on one side in the inside and outside two sides of expansion mating plate, and can be according to need inside the expansion mating plate
The light that mixing issues the LED into phosphor powder first penetrates the expansion mating plate, then penetrates the fluorescent tube and form secondary diffusion, and can produce
The raw uniform expansion light effect subsidized mutually with auxiliary.
And in TaiWan, China patent announcement the M503516th " LED lamp strip structure of tool lens cap " novel case, also disclose
Similar lamp bar structure comprising: a cover crystal circuit plate, multiple LED wafers and a lens cap;The cover crystal circuit plate side table
Face is equipped with multiple metallic conductors, and each LED wafer is electrically coupled on wantonly two adjacent metallic conductors, which is disposed on
On cover crystal circuit plate and each LED wafer is covered, is distributed with continuously coupled multiple bulge-structures in lens cover inner surface, and in
It can be coated with phosphor powder according to need in LED wafer surface or the lens cap, use and achieve the effect that uniform diffusing light.
Though above-mentioned two kinds of structures design can be such that light uniformly spreads, discomfort caused by dazzle, the light that LED is issued are reduced
Line successively passes through the expansion mating plate (lens cap) and fluorescent tube, certainly will form serious decaying, influences its whole illumination efficiency;Except this
Except, expansion mating plate (lens cap) element and its processing also result in the increase of fluorescent tube overall cost, and do not meet economic benefit.
