Description
Technical field
The invention belongs to technical fields such as optics, machinery, electronics, be specifically related to a great power LED lamp panel.
Background technology
At present, such as room lighting places such as school, market, bank, hospital, hotels, lamp panel structured illumination light fixture has been used widely, and current what generally use is common daylight grid lamp disc, generally is made up of fluorescent lamp, reflective aluminium flake, chassis.But this traditional lighting mode have the life-span short, safeguard that cumbersome, mercurous not environmental protection, power are more energy-conservation, while emergent ray dimness, shortcomings such as illuminating effect is undesirable, therefore, the LED lamp panel that forms by the led light source replace fluorescent lamps is the continuation development trend forward of lamp panel structure light fixture.Existing LED lamp panel adopts high brightness white light-emitting diode a new generation energy-conserving light source, than the fluorescent tube of traditional dim light, has advantages such as light efficiency height, little power consumption, life-span are long, easy to control, environmental protection.But lamp panel structure at present on the market and LED luminous intensity distribution and incompatible have the light lack of homogeneity, emergent ray too concentrate easily generation stronger wretched insufficiency such as dazzle the eyes, directly influence its development and application.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art part, provide have optical lens, use great power LED, LED and the even a kind of great power LED lamp panel of optical lens combination bright dipping.
The present invention is by the following technical solutions:
A kind of great power LED lamp panel comprises optical lens 1, large power white light LED lamp 2, lamp panel body 3, printed circuit board 4 and covers clear glass 5 at lamp panel body 3; Be fixed with printed circuit board 4 on the described lamp panel body 3, be welded with large power white light LED lamp 2 on the printed circuit board 4; Described optical lens 1 is made of exit end 8 and incident end 7, and the profile of incident end 7 is round table-like and tips upside down on the large power white light LED lamp 2, and the inner surface middle part of the exit end 8 that is connected with incident end 7 is provided with projection 6.
Described projection 6 is a reverse taper or parabola shaped.
The arc surface that the exit end 8 of described optical lens and the inner surface of incident end 7 are formed in one.
Described lamp panel body 3 is of a size of 1200mm * 600mm, 600mm * 600mm, 600mm * 300mm or 300mm * 300mm.
Described large power white light LED lamp 2 is evenly distributed on the described lamp panel body 3.
Also being provided with the power drives module that is used to control large power white light LED lamp 2 on the described printed circuit board, adopting the module powering mode, is that the unit powers separately with each row's large power white light LED lamp 2.
Among the present invention, can select the lamp panel main body and the great power LED quantity of different size according to different occasions, to reach rational illumination requirement.
The printed circuit board of LED below adopts the module powering mode, in a row places characteristics according to LED, is that the unit powers separately with each row LED, when guaranteeing that each group works alone, has further increased the stability and the reliability of light fixture work.
Adjust LED quantity by the concrete size of lamp panel, and the even riding position on lamp panel, the optical lens structure that cooperates independent innovative design simultaneously, what success solution led light source outgoing center light intensity caused excessively by force dazzles the eyes, and luminous intensity is even in the LED irradiated area, solves the problem of existing LED lamp panel emergent ray lack of homogeneity.
The main innovation part is newly-designed optical lens structure, described optical lens and LED are installed together, in lens exit end inner surface design projection 6, smooth behind the assurance light refraction toward dispersing all around, too concentrate near the central point thereby solve current LED emergent ray, produce the difficult problem of the illuminating effect of dazzling the eyes; Simultaneously the outer surface of the incident end 7 of optical lens 1 is designed to round table-likely, has guaranteed the emergent ray of sufficient intensity in the field of illumination when further converging emergent ray again, reach desirable illuminating effect.The present invention simultaneously has different embodiments according to the difformity of the projection in the optical lens 6, thereby produces different emergent raies, is optimized selection according to different illumination occasions, has realized the LED lamp panel structure that emergent ray is adjustable.
