Description
This case is the Application No. 2015101039770 using the applying date as 2015-03-10, entitled " big-angle LED lamp and
Wide-angle light extraction matches somebody with somebody optical assembly " the divisional application that is carried out for female case of patent of invention.
Technical field
The present invention relates to field of LED illumination, more particularly to big-angle LED lamp and wide-angle light extraction to match somebody with somebody optical assembly.
Background technology
LEDbulb lamp in the market, it is primarily used to replace conventional incandescent, its opticator mainly includes LED
Light source and lampshade, lampshade generally use diffusion shell, and the light that LED light source is sent forms diffusing transmission after directly getting to diffusion shell, made
Angle of the rising angle than LED light source in itself is bigger.LED since it is desired that radiating, it is necessary to using aluminium base fix on a heat sink,
So LED light-emitting window only has upward part.But such structure has a significant limitation, LED light source is in itself
Lighting angle size is limited, even across the diffusing transmission of lampshade, can not still realize that real wide-angle lights, and LED light source is arranged
LED particle is often can be seen close to lampshade edge in cloth, and granular sensation is not received by client.
In order to break through above-mentioned limitation, Application No. 201210342683.X application documents disclose a kind of wide-angle
LED illumination lamp, it sets light distribution panel in the top of LED-baseplate, multiple loopholes is densely covered with light distribution panel, and at least in the luminous intensity distribution
Plate is provided with reflector layer towards the lower surface of LED-baseplate, takes this, and the light being irradiated on light distribution panel can be reflexed to lamp by reflector layer
Bottom is covered, realizes wide-angle light-out effect, LED-baseplate can reflect away the light that light distribution panel reflects again, make lamp
The light of cover realizes that full angle is distributed.
Although the program can obtain larger lighting angle, can be dropped after multiple reflections by the light that reflector layer stops
Low-light level, and its bulb central part by loophole come printing opacity, brightness due to can only also be had a greatly reduced quality.Light distribution panel is individual flat simultaneously
Face, it can not accomplish that luminous intensity distribution is uniform, and reflection light is largely irradiated on aluminium base and absorbed, and efficiency is very low.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of big-angle LED lamp for not losing brightness and wide-angle light extraction
With optical assembly.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：A kind of big-angle LED lamp, including lamp housing,
Lamp holder, driving power and LED light source, one end of the lamp housing are provided with the lamp holder, the driving power, lamp are provided with inside lamp housing

Transmission and refraction, optics are located at the light direction side of LED light source, and the light collecting device is located at LED light source and optics
Between.
Another technical solution used in the present invention is：A kind of wide-angle light extraction matches somebody with somebody optical assembly, including optics and poly-
Optical device, the optics include medial surface and lateral surface, and optics is arranged to carry out thoroughly light by its medial surface
Penetrate and light is faced out transmission from its outside after reflecting, the light collecting device is outside the medial surface of optics.
The beneficial effects of the present invention are：Light is after LED light source injection, and by the optically focused of light collecting device, light is more
Intensively it is incident upon on optics, the light part that optics makes to be incident upon thereon is penetrated in the portion of directing out after diffusing transmission
Go out, another part reversely projects after diffusing reflection, so as to realize that the wide-angle for being closer to 360 degree lights, and realizing big angle
Brightness is hardly lost during degree is luminous；Meanwhile light is incident upon optics completely after the luminous intensity distribution of light collecting device
On, the granular sensation of light can be eliminated.
