Description

Technical Field

[0001] The utility model relates to a stage lamp, in particular to a non-equidistant lamp bead arrangement structure of a stage lamp module. Background Art

[0002] The optical efficiency of the module is the core performance indicator of the parameter. High efficiency is the goal that the enterprise pursues from beginning to end and is also the core competitiveness of the enterprise. Figure 1-Figure 2 As shown, the current module design is that the lamp beads are arranged equidistantly. In the LED substrate, the closer the lamp beads are to the center, the higher the luminous efficiency.

[0003] However, the distance between the lamp beads is too small, and the heat is too concentrated, which will increase the speed of lamp bead light attenuation and even damage the lamp beads. Secondly, the small distance between the lamp beads will increase the difficulty and even cost of processing the five matching optical components. Thirdly, the distance between the lamp beads is large, and the optical components built into the module have a large light receiving angle and low efficiency. Therefore, a new lamp bead arrangement method is very important to ensure heat dissipation and light efficiency while reducing the difficulty and cost of processing matching parts. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a non-equidistant lamp bead arrangement structure of a stage light module, improve the light efficiency of the module, and adjust the position of the lamp bead arrangement on the LED substrate to increase the light collection efficiency of the optical component.

[0005] The non-equidistant lamp bead arrangement structure of the stage light module of the utility model is realized by the following technical scheme: comprising a substrate, a housing, lamp beads, and optical parts;

[0006] The housing is fixed with an optical module, and the lamp chips are arranged regularly and welded on the substrate; the housing is mounted on the substrate, and the built-in optical components of the housing correspond to the positions of the lamp chips on the substrate;

[0007] The distance between adjacent lamp beads on any coaxial line decreases from the inside to the outside.

[0008] As a preferred technical solution, the distance between adjacent lamp beads is denoted as L. The central lamp bead is taken as the starting lamp bead, and the lamp beads are arranged from the inside to the outside in the coaxial direction in a manner such that the distance between adjacent lamp beads continuously decreases.

[0009] As a preferred technical solution, it is assumed that the temperature rise change between each adjacent lamp bead extending from the central lamp bead to the outside in any coaxial direction follows a certain increasing law, that is, the temperature rise difference between any adjacent lamp bead is 2.5 times the temperature rise increase of the previous lamp bead, which is formally expressed as T n+1 =T n +2.5 n , where T nis the temperature rise change value of the nth lamp bead, and n is the lamp bead number from the center lamp bead outward.

[0010] The beneficial effects of the utility model are as follows: the utility model is that the collimated light of the lamp bead in the middle and the light with a large collimation angle are easier to collect and the light collecting efficiency is high; the lamp beads at the edge have a large light collimation angle and are easily blocked by the shell; the second is that the edge lamp beads have a large light collecting angle and it is difficult to gather the light. After adjusting the arrangement of the lamp beads, the edge lamp bead chips are closer to the center of the light source module at a distance less than the equidistant distance, and the module will collect more light than the same equidistant light, thereby improving the efficiency of the module.

[0019] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0020] like Figure 3 — Figure 4 As shown, a non-equidistant lamp bead arrangement structure of a stage light module of the utility model includes a substrate 1, a housing 2, lamp beads 3 and an optical component 4;

[0021] The housing 2 is fixed with an optical module, and the lamp beads 3 are arranged regularly on the substrate 1; the housing 2 is mounted on the substrate 1, and the optical module corresponds to the position of the lamp beads 3 on the substrate 1.

[0022] Wherein, L represents the spacing in mm, T represents the temperature rise in °C, and E represents the efficiency.

[0023] Among them, the original spacing L1=L2=L3=L4 is changed to the arrangement distance of the lamp beads 3 on the coaxial line being L1 (unchanged)>L2>L3>L4.

[0024] The original temperature rise T1=T2+2=T3+4=T4+6 (T1 is the highest temperature point of the product) changes to T1(+1)=T2+2.5=T3+4.5=T4+6.5.

[0025] Therefore, the original efficiency E=(E1+E2+E3+E4) / 4=e changes to E=(E1+E2+E3+E4) / 4=e+(2~5)%.

[0026] From the above conclusions, it can be seen that when the temperature Tcmax increases by 1°C, the efficiency can be improved by 2 to 5 percentage points (in other words, when the temperature increment is acceptable, the efficiency is significantly improved).

[0027] like Figure 5 and Figure 8 As shown, the utility model also has the following arrangement methods, for example: non-equidistant hexagonal arrangement, non-equidistant circular arrangement, equidistant and non-equidistant hexagonal arrangement with the lamp beads farthest from the center close to the center, and non-equidistant circular arrangement with the lamp beads with large spacing in the middle close to the center.

[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
