Fig. 1,4 and 5 are please referred to, light source board 5 is equipped with multiple LED light sources 51, and multiple LED light sources 51 are in multiple concentric rings
Shape arranges, and the quantity of the LED light source 51 on each ring is successively successively decreased from outside to inside, the quantity of the LED light source in each sector 60
Identical and ecto-entad successively successively decreases, and the LED light source in each sector is set to the corresponding position in firstth area.
In the present embodiment, light source board 5 is equally divided into 15 sub-regions, and the corresponding central angle of each subregion is 24 °,
In each subregion, it is uniformly arranged LED light source 51 in the 0th ° to the 8th ° of region, is not provided in the 8th ° to the 24th ° of region
LED light source 51.
In the present embodiment, the first area 61, the corresponding central angle in the second area 62 and third area 63 are 8 °.Using uniform
Angular divisions, to facilitate the setting of the rotating mechanism of 5 relative lens 6 of light source.
Fig. 3 Fig. 6 and Fig. 7 are please referred to, it includes transflector mirror in complete that lens 6, which are located at the first area 61 and the part in the second area 62,
600 and the side of being covered on it a part of planar lens 601, it is complete in transflector lens 600 be an arc strip shape body, including top
Face 64, bottom surface 65, and the lateral surface being connected between top surface 64 and bottom surface 65, top surface 64 are light-emitting surface, the width of top surface 64
Greater than the width of bottom surface 65, fluted 67 are formed on bottom surface 65, LED light source 51 corresponds to the lower section for being located at groove 67, groove 67
Inner wall be incidence surface, it is complete in the lateral surfaces of transflector lens 600 be total reflection side 66, total reflection side 66 is for will be from entering
The light that smooth surface refraction is come in is reflected and is emitted from light-emitting surface.The structure of transflector lens 600 in complete is shown in Fig. 7.
In the present embodiment, the light-emitting angle of the first part 6001 of complete interior transflector lens 600 and second part 6002
It is not both to be determined by 66 difference of total reflection side in the first area 61 and the second area 62.In the sectional view of Fig. 5, in order to relatively more clear
Chu, by the complete interior transflector lens 600 in the first area 61 along the sectional view of 6 radius of lens and the complete interior transflector lens in the second area 62
600 are superimposed along the sectional view of 6 radius of lens.The top surface 64 and bottom surface 65 of the two are respectively superposed, and are totally reflected side
66 are not overlapped.The total reflection side 66 of the first part 6001 of transflector lens 600 is the first arcwall face 611 in entirely, complete interior saturating
The total reflection side 66 of the second part 6002 of mirror lens 600 be the second arcwall face 621, and the first arcwall face 611 go out light
Light-emitting angle of the angle less than the first arcwall face 611.
From the sectional view of Fig. 6, the total reflection side 66 positioned at the first area 61 has the first section curve, is located at the
The total reflection side 66 in two areas 62 has the second section curve.Compared to the first section curve, the second section curve is located at outside,
And the two is non-intersecting.That is, (the second arcwall face of total reflection side 66 of the second part due to complete interior transflector lens 600
621) it is located inside, curvature is smaller, and thus the second part 6002 of complete interior transflector lens 600 is formed by light-emitting angle more
Greatly.Conversely, as the first arcwall face 611 is located at outside relative to the second arcwall face 621, curvature is larger, thus complete interior transflection
Penetrating the first parts 6001 of lens 600, to be formed by light-emitting angle smaller.
Specifically, the first section curve and the second section curve can be circular arc simultaneously, and the curvature of the first section curve is partly
Diameter is greater than the radius of curvature of the second section curve namely the radius of curvature of the first arcwall face 611 is greater than the song of the second arcwall face 621
Rate radius；Alternatively, the first section curve and the second section curve are elliptic arc and the second section curve relative to the first section
Curve protrudes outward；Or first section curve and the second section curve is parabola and the second section curve is opposite
It is protruded outward in the first section curve.
Boundary in corresponding first area 61 and the second area 62, the total reflection side 66 positioned at the first area 61 transits to second
The total reflection side 66 in area 62.
In the present embodiment, the light-emitting angle of the first part 6001 of complete interior transflector lens 600 is 60 °, complete interior transflection
Penetrate the second part 6002 of lens 600 light-emitting angle be 90 °, third area 63 can obtain than the second area 62 light-emitting angle more
Big light-emitting angle, it is preferable that the light-emitting angle in third area is 120 °.
Fig. 4 and Fig. 5 are please referred to, at this time the LED light source 51 on the 61 alignment light source plate 5 of the firstth area of lens 6, corresponding second
Without LED light source 51 in area 62 and third area 63.The LED light of 67 lower section of groove of the complete interior transflector lens 600 in the first area 61
The light that source 51 issues is emitted after incidence surface refraction, total reflection side 66 are reflected from light-emitting surface, obtains a kind of light-emitting angle
Light-emitting mode.When light source board 5 to be rotated to the LED light on the 62 alignment light source plate 5 of the secondth area for making lens 6 clockwise
Source 51, since the total reflection side 66 that the light-emitting angle that the total reflection side 66 in the second area 62 is determined is greater than the first area 61 is determined
The light-emitting mode of another light-emitting angle can be obtained in fixed light-emitting angle at this time.Continue clockwise to turn light source board 5
The dynamic LED light source 51 made on the 63 alignment light source plate 5 of third area of lens 6, since third area 63 is without complete interior transflector lens
600, therefore, light can obtain bigger light-emitting angle directly by the refraction of the planar lens 601 of planar lens 6
Light-emitting mode.
The analog result of a specific embodiment of the utility model is given below.
In this specific embodiment, the width of the top surface 64 of lens 6 is 11.7mm, and the width of bottom surface 65 is 7.6mm, thickness
For 6mm, distance of 51 light-emitting area of LED light source away from bottom surface 65 is 0.2mm.
The analog result of 1 specific embodiment of table
| Light source board rotates clockwise angle (°) | It simulates beam angle (°) |
| 0 | 64 |
| 8 | 85 |
| 16 | 105 |
When LED light source 51 is directed at the first area 61 of lens 6, obtained simulation beam angle is 64 °, realizes 60 ° of luminous moulds
Formula；When LED light source 51 is directed at the second area 62 of lens 6, obtained simulation beam angle is 85 °, realizes 90 ° of light-emitting modes；When
LED light source 51 is directed at the third area 63 of lens 6, and obtained simulation beam angle is 105 °, realizes 120 ° of light-emitting modes.
Fig. 1 to 3 is please referred to, lid 3 includes that the upper cover 32 mutually fastened and lower cover 31, lower cover 31 are connect with radiating piece 2, on
Lid 32 and lens 6 fasten, light source board 5 be set to upper cover 32 and with the concentric rotation connection of upper cover 32, therefore, light source board 5 being capable of phase
