Abstract
The invention discloses an optical lens and an LED lamp. The optical lens comprises a lens body. Upper bosses used for secondary light distribution are arranged on the upper surface of the lens body. Lower bosses used for light collection are arranged on the lower surface of the lens body. Each upper boss corresponds to one or more lower bosses. Light of an LED chip is gathered and collected through the lower bosses, losses of the light are reduced, the light is then secondarily distributed through the upper bosses, and the evenly-distributed light is obtained. After the light passes through the lower bosses and the upper bosses, a dazzle light index is lower, and the use comfort level is increased.

Detailed description of the invention
Technical scheme and the technique effect reached for making to present invention solves the technical problem that, using are clearer,
Further illustrate technical scheme below in conjunction with the accompanying drawings and by detailed description of the invention.
Embodiment 1
Referring to figs. 1 to Fig. 6, present embodiments providing a kind of optical lens, including lens body 1, lens are originally
The upper surface of body 1 is provided with the convex platform 11 for secondary light-distribution, and the lower surface of lens body 1 is provided with use
In the lower convex platform 12 of receipts light, each convex platform 11 one or more lower convex platform 12 corresponding.Lower convex platform 12 will
The light of LED chip converges to be collected, and reduces the loss of light, then carries out secondary distribution by convex platform 11, it is thus achieved that
Equally distributed light, and light is after lower convex platform 12 and convex platform 11, glare index is lower, improves and makes
Use comfort level.
The cross section of convex platform 11 includes convex arc line, can uniformly distribute when light passes through, it is thus achieved that bigger illumination
Angle, uniform light is soft.Refer to using Fig. 5 and Fig. 6 as reference, the bottom of the cross section of lower convex platform 12
The top of the lower convex platform 12 of Fig. 6, the top of the cross section of lower convex platform 12 refers to the lower convex platform 12 times of Fig. 6
Portion, the bottom width of the cross section of lower convex platform 12 is more than top width, the both sides of the cross section of lower convex platform 12
The most outward-dipping.Concrete, the both sides of the cross section of lower convex platform 12 are skew lines or song
Line.Light is after the top of lower convex platform 12 enters, and a part of light enters convex platform 11 directly through lens body 1,
Another part light is dispersed into the both sides of lower convex platform 12, owing to being dispersed into the incidence of the light of the both sides of lower convex platform 12
Angle is very big, and lower convex platform 12 is again optically denser medium compared with air, therefore can be totally reflected, and is dispersed into down convex
The light of the both sides of platform 12 will be all-trans and be emitted back towards in lens body 1, and then by convex platform 11 secondary distribution, greatly
Fall lacked the loss of light.
Convex platform 11 is arranged at the upper surface of lens body 1 ringwise, and light is distributed by the convex platform 11 of annular
After, light not only uniformly mixes at the light of all directions of the cross section of convex platform 11, and in loop configuration
In whole space, the light of all directions uniformly mixes, and illuminates the softest, reduces glare index further.
Multiple convex platforms 11 are distributed on the upper surface of lens body 1 in concentric annular so that the light of whole optical lens
Can uniformly mix.Convex platform 11 can be interrupted or arrange continuously, and being interrupted the convex platform 11 arranged can make
Obtain light and present different effects, to adapt to different application scenarios.
Single lower convex platform 12 or multiple lower convex platform 2 are corresponding with the position of convex platform 11, therefore, and lower convex platform 2
Entirety is arranged the most ringwise, but when multiple lower convex platforms 2 are corresponding with convex platform 11,2 need of lower convex platform
Will be in the range of convex platform 11, lower convex platform 2 is the most ringwise, it is also possible to for
Straight line is arranged, or other modes are arranged.Lower convex platform 12 can be interrupted or arrange continuously, if LED core
Sheet is corresponding with lower convex platform 12.
The number of LED chip can change according to the demand of application scenario, if LED chip under convex
The lower section of platform 12, the LED chip of varying number can also use same optical lens, it is not necessary to
Change optical lens, cost-effective.
Preferably, the convex platform 11 of multiple continuous print annular is distributed on the upper surface of lens body 1 in concentric ring,
The corresponding lower surface in lens body 1 of each convex platform 11 is provided with the lower convex platform of a continuous print annular
12, the light of LED chip is directly entered the convex platform 11 of correspondence, secondary distribution back lighting after lower convex platform 12
Effective, under loop configuration, LED chip has only to the most uniform, it is simple to arrange that LED is at PCB
Position on plate.
In order to preferably be fixed with pcb board by optical lens, the lower surface of lens body 1 is additionally provided with use
In the support column 13 of abutting pcb board, optical lens is abutted pcb board, it is simple to location.Lens body 1
Lower surface be additionally provided with and insert pcb board and carry out the locating dowel 14 that positions, locating dowel 14 is arranged at support column
The top of 13, the surface configuration of pcb board has and positions hole accordingly, after locating dowel 14 inserts hole, location, supports
Post 13 is connected to the surface of pcb board, completes location.
Embodiment 2
As different from Example 1, the convex platform 11 of the present embodiment is linearly arranged at the upper of lens body 1
Surface, after light is distributed by the convex platform 11 of straight line, light is at the light of all directions of the cross section of convex platform 11
Uniformly mixing, in whole space, the light in the direction linearly arranged uniformly mixes, and can meet different answering
By the demand of occasion.Convex platform 11 can be interrupted or arrange continuously, and being interrupted the convex platform 11 arranged can make
Obtain light and present different effects, to adapt to different application scenarios.
Single lower convex platform 12 or multiple lower convex platform 2 are corresponding with the position of convex platform 11, therefore, and lower convex platform 2
Entirety is the most linearly arranged, but when multiple lower convex platforms 2 are corresponding with convex platform 11,2 need of lower convex platform
Will be in the range of convex platform 11, lower convex platform 2 is the most linearly, it is also possible to for
Other modes are arranged.Lower convex platform 12 can be interrupted or arrange continuously, if LED chip and lower convex platform 12 phase
Corresponding.
