Abstract
Use Emitting Diode (Light-Emitting Diode, LED) in the backlight module has more and more generally, and wherein several the most important factors are luminance and the degree of consistency of Light, for making backlight module can have even Light distribution, solve Emitting Diode (Light-Emitting Diode, LED) Light distribution inhomogeneous, the utility model discloses an even secondary optical lens that can merge square Light distribution can be used to backlight module in, can merge square Light distribution and play an even Light distribution cover.
Description
Technical field
The demand of backlight module is a uniform light-emitting area, and use light emitting diode (light-emitting diode,
Led) its light distribution need to be improved in collocation camera lens.
Background technology
More and more universal using light emitting diode (light-emitting diode, led) in backlight module, wherein
Most important several factor is brightness and the uniformity of light, and light emitting diode (light-emitting diode, led) sends
Light distribution be circle, and the brightness of central point can be the brightest, and distance is more remote weaker, such as by multiple light emitting diode (light-
Emitting diode, led) arrangement, light distribution overlapping portion branch is overlapped mutually, and therefore has the uneven problem of light distribution.
Utility model content
The purpose of this utility model effect, that is, enable backlight module to have uniform light distribution, solving light emitting diode
The light distribution of (light-emitting diode, led) is uneven, by square light distribution and rise can have a uniform light distribution
Face.Of the present utility model uniformly can and the secondary optics camera lens of square light distribution can be used in the backlight module of each form, such as liquid
Crystal display, TV, electronic instrument panel etc..
Brief description
Fig. 1 be uniformly can and the secondary optics camera lens of square light distribution schematic diagram；
Fig. 2 be uniformly can and the secondary optics camera lens of square light distribution schematic top plan view；
Fig. 3 be uniformly can and the secondary optics camera lens of square light distribution diagonal schematic cross-section.
Wherein, description of reference numerals is as follows:
1 square camera lens
The upper surface of 11 free form surfaces
Article 111 4, what camber line was constituted is square
It is square that 112 tangent lines are constituted
The diagonal section of 12 square camera lenses
2 light sources
3 wiring boards
Specific embodiment
About of the present utility model aforementioned and other technology contents, feature and effect, coordinate with reference to schema relatively following
In the detailed description of good embodiment, can clearly present.Before the utility model is described in detail it is noted that,
In the following description content, similar element is to be represented with being identically numbered.
With reference to Fig. 1, in first embodiment of the present utility model, a kind of uniformly can and square light distribution secondary optics camera lens
Specifically include that
One square camera lens 1, has the square structure of free form surface；One light source 2, between lens and wiring board；One line
Road plate 3, can make light source 2 light positioned at bottom；Its function is through square camera lens 1, the light source 2 on wiring board 3 can be not required to periphery to hide
Light can directly project the high efficiency beam of uniform square light distribution.Uniformly can and square light distribution secondary camera lens, its square mirror
The head upper surface 11 comprising free form surface and be made up of four camber lines square 111.Uniformly can and square light distribution secondary mirror
Head, be made up of four camber lines square the 111 of its square camera lens, square the 112 of the tangent line composition of the peak of its four camber lines,
Can be square or rectangular, the difference of its total length of side and four arc length is less than 1.7 times of center to the beeline of the length of side.Uniformly
Can and square light distribution secondary camera lens, the diagonal section 12 of its square camera lens be shaped as the bat-wing of indent evagination from
By curved surface.Uniformly can and square light distribution secondary camera lens, its light source 2 can be any species, such as bulb, light emitting diode
(led) etc..Uniformly can and square light distribution secondary camera lens, its wiring board 3 be any type of circuit.
But, the foregoing is only preferred embodiment of the present utility model, when the utility model can not being limited with this
The scope implemented, that is, generally according to claims of the present utility model and description of the present utility model made simple etc.
Effect change with modify, all still belong in the range of the utility model patent covers.
