Example 1

As shown in Figures 1 to 2, this embodiment provides a light source 1, which includes a tube body 101, an LED magic light strip 20, a light pattern controller 21, and a power supply system 22. The LED magic light strip 20 includes a strip body 103. Multiple LED illusion lamp beads 104, multiple LED dual color temperature lamp beads 105, and peripheral circuits 102; the peripheral circuit 102 is arranged along the belt body 103, multiple LED illusion lamp beads 104 and multiple LED dual color temperature lamp beads 105 are respectively arranged on the belt body 103 and arranged alternately along the belt body 103. Each LED magic color lamp bead 104 and each LED dual color temperature lamp bead 105 are electrically connected to the peripheral circuit 102. The belt body 103 is a flexible circuit board, and the tube The body 101 is a metal circular tube, and the belt body 103 is arranged on the outer circumferential side of the tube body 101 along the cylindrical spiral direction of the tube body 101 and extends along the axis direction of the tube body 101; the length and diameter of the tube body 101, the LED magic The number of lantern strips 20, the pitch of the predetermined spiral path, and the number of turns can be selected according to actual needs. The LED phantom lamp bead 104 is an RGB lamp bead with a built-in IC control chip and is responsible for emitting colored RGB light. The LED dual-color temperature lamp bead 105 is responsible for emitting white light with different color temperatures. The LED phantom lamp bead 104 and the LED dual-color temperature lamp bead 105 are along the Predetermined spiral paths in the direction of the cylindrical spiral of the tube body 101 are alternately distributed. The light source 1 can achieve 360° annular lighting, and the light pattern controller 21 controls the LED magic beads 104 at different positions distributed spirally around the tube body to emit light with different colors, different brightness, different color temperatures and other parameters to achieve colorful, A 360° annular two-dimensional light pattern effect of varying light and dark, which can change and remain continuous in the horizontal and vertical directions of the ring; by controlling the LED dual-color temperature lamp beads 105 to emit light through the light pattern controller 21, different color temperatures can be achieved White light effect.

Assume that the total number of LED magic beads 104 linearly arranged and distributed on the LED magic light strip 20 is N, and the numbers of the lamp beads are sequentially marked with Q1 to QN respectively. The length coordinates of the belt position where the LED magic beads 104 are located are L _Q1 -L _QN respectively. The LED magic beads 104 are equidistantly distributed. Among them, L _Q1 =0, then it can be concluded that L _QN = (N- 1)×L _Q2 , for example: L _Q3 =L _Q2 ×2.

The magic light strip 20 is spirally wound around the tube body 101. Relative to the center point at the bottom of the tube body 101, the position parameters of the LED magic light beads 104 on the outer surface of the tube body 101 include the angle α and the height H. The angle α ₁ =0 and the height H ₁ =0 of the first LED magic bead 104 on the bottom strip body 103; correspondingly, N LED magic beads with different numbers on the strip body 103 all have unique The position parameters of lamp bead Q1 are (α _Q1 , H _Q1 ), lamp bead Q2 is (α _Q2 , H _Q2 ), and lamp bead QN is (α _QN , H _QN ).

The light pattern of the tubular light source includes lamp bead position information W (α, H) and light parameter information L _P (RGB color, brightness, etc.). Specifically, the light of the k-th lamp bead W _k (α _k , H _k ) The parameter is L _Pk . The light pattern controller 21 stores preset light patterns. In different light patterns, the same lamp bead position information W _{k corresponds to} different light parameter information L _Pk . The light pattern controller 21 is actually an LED magic light pattern.

The above-mentioned pre-set light pattern can also be personalized adjusted through the input module of the light pattern controller 21, such as the adjustment of light parameters, and the adjusted light pattern is sent to the output control module of the light pattern controller 21, and finally It is sent to the LED magic light strip 20 to realize personalized adjustment of the light pattern. In addition to the preset light patterns of the system, a brand new light pattern can also be created. For example, the input module of the light pattern controller 21 is provided with the lamp bead position information W and the light parameter information L _P located on the outer surface of the tube body 101. Corresponding plane drawing board, different light patterns can be designed on the plane drawing board, and the light pattern can be realized on the light source of the present application through the control output module of the light pattern controller 21.

The height of the tube body 101 with the LED magic light strip 20 spirally wound and distributed in the axis direction is Y, the number of winding turns is T, and the average pitch of the spiral path is A=Y/ T, the outer circumference of the cross section of the tube body 101 perpendicular to the axis is C.

Experiments have found that the smaller the outer circumference C of the tube 101 and the larger the average pitch A, the closer the light pattern formed by the light source 1 is to a one-dimensional linear light pattern. In order to avoid the one-dimensional light pattern effect and obtain better two-dimensional light Pattern, need to meet: 1.5×C>A.

The experiment also found that in order to obtain a 360° annular two-dimensional light pattern effect, more than one LED magic bead 104 needs to be distributed within an outer circumference of the tube body 101 to achieve a horizontal light pattern. Further research found that LED magic lights After the light strip 20 is spirally wound on the tube body 101, in addition to the spiral line of the original light strip wound along the predetermined spiral path, the LED magic beads 104 spirally wound on the adjacent light strips in the axial direction of the tube body 101 are along the upper and lower parts of the tube body. The direction also forms several oblique equivalent spiral lines. When the LED magic light strip 20 emits light, it is equivalent to the LED magic light beads 104 on the equivalent spiral line emitting light to form a two-dimensional light pattern. The outer circumference of the tube body 101 is C. The smaller the lamp bead spacing M is, the sparser the equivalent spiral is, and the light pattern is closer to a one-dimensional linear light pattern. After testing, it is found that when the outer circumference C of the tube body 101 is > 1.5×M, the light pattern is The two-dimensional effect can be greatly improved, and the larger C and the smaller M, the better the two-dimensional effect of the light pattern.

The experiment also found that there is a certain range of variation in the transverse density and longitudinal density of the LED magic beads 104 distributed on the outer surface of the tube body 101. In order to obtain a better two-dimensional light pattern effect, especially a 360° annular two-dimensional light pattern For the transverse changing effect, the transverse density of the LED magic beads 104 distributed on the outer surface of the tube body 101 will be intentionally pursued to be greater than the longitudinal density.
