Light source substrate 14 is the installation foundation of LED lamp bead 12 and lens 10, while light source substrate 14 is additionally operable to as LED light
Pearl 12 provides electric energy.Driving module, which can also enter input signal in light source substrate 14, realizes the control to LED lamp bead to realize
Light modulation toning.Light source substrate 14 is typically the slab structure of strip, therefore it is with apparent length direction.Light source substrate 14
On need that multiple lens 10 are arranged, two are at least arranged under normal conditions, and according to the concrete type and demand of panel light, thoroughly
The quantity of mirror 10 can also adjust accordingly again.These lens 10 are towards diffuser plate 2, and along the length side of light source substrate 14
To arranging successively, the long axis direction of the cartouche of lens 10 is consistent with the length direction of light source substrate 14, binding face 100 with
Light source substrate 14 fits, and can be bonded by bonding agent therebetween.
Since the light source substrate 14 of illuminating module 1 is in strip, and lens 10 and LED lamp bead 12 are also each along light source base
The length direction of plate 14 is arranged, therefore the range of exposures of illuminating module 1 is substantially width with the long axis direction of its elliptical spot
Degree, with the range for the strip that the length direction of light source substrate 14 extends.And for panel light, usually require planar
Illumination range, thus in panel light illuminating module 1 quantity at least two, these illuminating modules 1 can along perpendicular to light
The direction parallel interval arrangement of the length direction of source substrate 14, particular number can be again adjusted according to the demand of panel light.
In this way, range of exposures can be extended on the length direction perpendicular to light source substrate 14, makes its presentation
Go out the illumination range of planar.
For example, for the panel light of 600*600*60mm, the quantity of required illuminating module 1 is two, wherein every
The quantity of lens 10 inside a illuminating module 1 is 9, and the quantity of the LED lamp bead 12 inside each lens 10 is 2.
That is in panel light at this time, the quantity of lens 10 is 18, and the quantity of LED lamp bead 12 is 36, the quantity of light source substrate
It is 2.It is greatly decreased compared with prior art, therefore cost is accordingly also greatly reduced.
When multiple 1 parallel arrangements of illuminating module, in order to show uniform hot spot, adjacent two discharge on diffuser plate 2
Illumination range between optical mode group 1 is not completely separated, but needs to show partly overlapping effect on diffuser plate 2.With
This simultaneously, the illumination range of the two neighboring lens 10 on same light source substrate 14 is also required to partly overlap, these
Overlapping range influences whether the uniformity of light.And the spacing phase between overlapping range and diffuser plate 2 and illuminating module 1
It closes, therefore is L1 with the spacing between two neighboring illuminating module 1, length direction of the two neighboring lens 10 in light source substrate 14
On spacing be L2, the spacing of lens 10 and diffuser plate 2 is OD, and OD will meet following two conditions simultaneously：OD>0.2L1 and OD>
0.89L2.It is found by modeling, when OD is under the conditions of two above, the uniform light degree of diffuser plate 2 is higher.
For current common panel light model, L1 260-270mm, L2 57-67mm, OD 45-55mm.Such as
In 600*600*60mm panel lights, L1 265mm, L2 62mm, OD 50mm.
The transmitance of itself of diffuser plate 2 also influences whether final uniform light effect.Under normal conditions, in order to obtain more
High intensity of illumination, it is even higher that a transmitance of diffuser plate 2 can generally be maintained at 65%.And due to shining in the present embodiment
The negligible amounts of module 1, LED lamp bead 12 are also more concentrated, therefore even if the uniformity of light is higher, i.e., bright on diffuser plate 2
It is larger to spend minimum value/brightness maxima, but high-brightness region is still more concentrated.It at this time can be by the primary transmission of diffuser plate 2
Rate is maintained in the interval range of 50%-60%.A transmitance by suitably reducing diffuser plate 2 can further further height
The luminance difference of luminance area and low brightness area further increases the uniformity of light.
To carrying out Luminance Distribution detection at the 600*600*60mm panel lights using scheme in the present embodiment in fig. 2 A-A,
Testing result is referring to Fig. 9, brightness minimum value/brightness maxima>85%.
Lens, illuminating module and panel light disclosed in the embodiment of the present application can pass through the less LED lamp bead of quantity, lens
And light source substrate can ensure the uniform light of diffuser plate, therefore cost is greatly reduced.
Emphasis describes the difference between each embodiment in the application foregoing embodiments, different between each embodiment
