The beam angle of the light for appearing diminishes, corresponding, and the also brightness of the light after aggregation increased.Meanwhile, warp
The left side of the light deflection fluorescent tube 1a of luminous intensity distribution portion 12a is crossed, that is, deviates light source assembly 2a exiting surfaces 221a's
Normal direction N2, therefore, the light sent from light source module 100a has polarizing angle.Additionally need
It is bright, during LED luminescence units 22a can also be arranged at the centre position 211a of substrate 21a or be located at
Between position 221a right side.When LED luminescence units 22a is located at substrate 21a left sides, from luminous intensity distribution portion 12a
The light polarizing angle of injection is small, when LED luminescence units 22a is located at substrate 21a right sides, from luminous intensity distribution
The light polarizing angle that portion 12a is projected is big, therefore, by adjust LED luminescence units 22a in substrate
Position on 21a, can adjust the size of the polarizing angle that light source module 100a emits beam.
Fig. 7 is the corresponding distribution curve flux figures of light source module 100a, as shown in fig. 7, light source assembly 2a sends
Light by after luminous intensity distribution portion 12a, beam angle is about 22 degree (0 to 22 degree), and light off-normal
About 10 degree of direction N2.
In summary, by after the luminous intensity distribution portion 12a luminous intensity distributions of fluorescent tube 1a, from the light that light source module 100a sends
Line beam convergence of corner, and certain polarizing angle is formed, when light source module 100a is applied to lighting device
Afterwards, can realize that light concentration is shone object and brightness also complies with demand, you can to meet in specific region
Or the illuminating effect on object.Such as when light source module 100a application normal linear light fixtures, and the linear modulation
Tool as wall lamp to use when, being installed on the linear light fixture of ground can realize that light is concentrated on positioned at its side
Side washed on metope certain need to wash the region of wall, and light luminance meets and washes wall requirement.Again such as,
When light source module 100a is applied to normal linear light fixture, and the linear light fixture as shelf lamp to use when,
Being installed on the linear light fixture taken in day can realize that light concentrates on the goods positioned at its side-lower, and light is bright
Degree meets demand.Simultaneously as the element in light source module 100a is few, therefore, light source module 100a knots
Structure is simply easily assembled to and low cost of manufacture.

It is electrically connected with each other between LED luminescence units 22b.The substrate 21b closing semicircle arcuations of light source assembly 2b
Fluorescent tube 1b.In addition, the part on fluorescent tube 1b inner surfaces 12b just to LED luminescence units 22b is not provided with
There is the light that micro-structural 13b, LED luminescence unit 22 sends from the above-mentioned part for being not provided with micro-structural 13b
Linear extension and go out.
The rectangular triangles of base 3b, the substrate 21b of light source assembly 2b is affixed on the inclined plane of base 3b
On.Therefore, the light that light source assembly 2b sends can also incline certain angle, that is, deviate vertical direction N4,
Vertical direction N4 is perpendicular to horizontal direction.
Fig. 8 is the index path corresponding to fluorescent tube 1b, as shown in figure 8, being sent out from the LED of light source assembly 2b
The light that light unit 22b light-emitting areas 221b sends enters the points of side 1311b and second of the first pointed tooth 131b
Inside contracted after being reflected after the side 1321b of tooth 132b and flocked together, i.e., by micro-structural in fluorescent tube 1b
After the secondary light-distribution of 13b, the beam angle of the light appeared from fluorescent tube 1b diminishes, corresponding, after aggregation
The brightness of light is also increased.Meanwhile, by light and the LED luminescence unit 22b light-emitting areas of fluorescent tube 1b
The normal direction N3 of 221b is consistent, yet with the presence of base 3b, by the light of fluorescent tube 1b
Deviate vertical direction N4, vertical direction N4 is perpendicular to horizontal direction.
Fig. 9 is the corresponding distribution curve flux figures of light source module 100b, as shown in figure 9, light source assembly 2b sends
Light by after fluorescent tube 1b, beam angle is about 60 degree (minus 40 degree to minus 100 degree), and light is inclined
About 70 degree from vertical direction N4.
In summary, by after the luminous intensity distribution of fluorescent tube 1b, from the light beam angle meeting that light source module 100b sends
Poly-, simultaneously because the presence of inclined base 3b, the light for sending forms certain polarizing angle, works as light source
After module 100b is applied to lighting device, can realize that light concentration is shone object and brightness is also complied with and needed
Ask, you can to meet the illuminating effect on specific region or object.Such as when light source module 100b is applied
Normal linear light fixture, and the linear light fixture as wall lamp to use when, be installed on the linear light fixture energy of ground
Enough realize light concentrate on positioned at its side washed on metope certain need to wash the region of wall, and light is bright
Degree meets washes wall requirement.Again such as, when light source module 100b is applied to normal linear light fixture, and this is linear
Light fixture as shelf lamp to use when, be installed on the linear light fixture taken in day and can realize that light is concentrated on and be located at
The goods of its side-lower, and light luminance meets demand.Meanwhile, due to the element in light source module 100b
It is few, therefore, light source module 100b simple structures are easily assembled to and low cost of manufacture.
Above-described instantiation, has carried out entering one to the purpose of the present invention, technical scheme and beneficial effect
Step is described in detail, be should be understood that and be the foregoing is only specific embodiment of the invention, and without
In limitation the present invention, all any modifications within the spirit and principles in the present invention, made, equivalent,
Improve etc., should be included within the scope of the present invention.
