Background
The light guide plate is the main component part of backlight unit, and the light guide plate utilizes optics level ya keli/PC panel, then with having high refractive index and the high-tech material that does not absorb light, with the rapid development of L ED area light source in recent years, L ED area light source side is luminous gradually becomes the main trend that the illumination market developed, and the light guide plate performance plays very important effect to performances such as the degree of consistency, luminance, light efficiency of light-emitting.
Even light-emitting is realized through laser sculpture leaded light hole at the light guide plate that uses at present, but is being less than enough to light penetration under the great condition of light guide plate thickness or area, and light intensity receives the influence great, and the not enough condition of luminance appears easily in whole light guide plate, so needs the targeted improvement design, solves above-mentioned problem.
Disclosure of Invention
The present invention is directed to a light guide plate for uniformly emitting light and a lamp thereof, which are used to solve the problems of the related art.
In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a light guide plate of even light-emitting, includes the combination formula light guide plate that forms and the reflectance coating of adhesion in combination formula light guide plate play plain noodles one side by the concatenation of the leaded light strip that supports in proper order through a plurality of, a plurality of round platform form leaded light hole has evenly been seted up to gap department between the adjacent leaded light strip, round platform form leaded light hole is pieced together, a plurality of by the half hole that two adjacent leaded light strip edges were seted up whole arc that is after the leaded light strip concatenation.
Preferably, the bottom end of the circular truncated cone-shaped light guide hole extends to form a hexagonal prism-shaped hole groove, the hexagonal prism-shaped hole groove gradually converges from top to bottom, and the cross section of the hexagonal prism-shaped hole groove gradually decreases.
Preferably, the periphery of the combined light guide plate is pasted with a piece of shading paper, and the light guide strip is made of organic glass.
Preferably, the outer side of the combined light guide plate is hooped with a rubber frame.
A luminaire comprising a light source, said luminaire further having the modular light guide of any of claims 1 to 4.
Preferably, the outer side joint of combination formula light guide plate has the aluminum alloy frame, and the light source sets up in the inboard side of aluminum alloy frame.
The invention has the technical effects and advantages that: the light guide plate and the lamp with uniform light emission,
the light guide strips that lean on in proper order through a plurality of splice into combination formula light guide plate, set up cylinder leaded light hole in clearance department simultaneously to it is faster to extend and set up reflection frequency of hexagonal prism type hole groove light in the gap of combination formula light guide plate and round platform leaded light hole, and the stroke of light in the light guide plate is longer, and the permeability is stronger, thereby guarantees that whole light guide plate luminance is stronger, and the light-emitting is more even, and the light efficiency is better, and this lamps and lanterns real luminance is stronger, and the light efficiency is better.
