Description
Technical field
The utility model relates to a kind of light aberration pick-up unit, relates in particular to a kind of LED light color device for detecting difference.
Background technology
LED is the abbreviation of light emitting diode, and it has long service life, consumes energy low, and volume is little and react the feature such as fast, replaces conventional bulb gradually and is applied in various light-emitting devices, if luminous LED lamp is exactly wherein one of to apply.The white light that LED lamp bar sends is synthetic by the color of three passages of red, green, blue, and the composition of every kind of light all can be divided into 0(black) to 255(white) value.In the time that the value of three kinds of colors is 255, result is pure white light, and in the time that this value is 0, result is black.Every kind of wherein all difference of value of the light of every kind of color of light that LED lamp sends, the light therefore sending is all differentiated, too large if the light that LED of the same race etc. send departs from Standard Colors, is substandard product.Because LED lamp wiring is too strong, cannot observe out the aberration such as LED preferably, must use instrument and distinguish.
Summary of the invention
The utility model has overcome the deficiencies in the prior art, and a kind of LED light color device for detecting difference simple in structure is provided.
For achieving the above object, the technical solution adopted in the utility model is: a kind of LED light color device for detecting difference, comprise: be successively set on the pickup groove on support, opaque shadow shield, prism and color board, it is characterized in that, described pickup groove is provided with positive and negative power supply lead-in wire, described shadow shield is provided with perforate, described perforate is positioned on the line at described pickup groove and described prism middle part, described prism two ends symmetry be provided with the rotating shaft that can be rotatably connected on described support, described color board is provided with some scale marks, described scale mark is parallel to the seamed edge of described prism.
In preferred embodiment of the utility model, the xsect of described prism is leg-of-mutton cylindricality prism.
In preferred embodiment of the utility model, on described shadow shield in the horizontal direction or vertical direction be provided with multiple described perforates, each described perforate is corresponding described pickup groove, described prism and the described color board of being provided with all.
In preferred embodiment of the utility model, the described color board back side is provided with universal bearing, and described universal bearing is fixedly connected on described support.
In preferred embodiment of the utility model, described perforate is circle hole shape perforate.
In preferred embodiment of the utility model, between multiple described perforates, adopt opaque baffle interval, described dividing plate is arranged on described shadow shield and is positioned at described pickup groove one side.
The utility model has solved the defect existing in background technology, the utility model utilizes the light-dividing principle of prism, the light that LED lamp is sent is demarcated, and the vitta after light splitting and standard vitta are contrasted, draw the aberration of LED lamp, the scale mark arranging on color board can facilitate the vitta after testing staff decomposes prism to compare, easy to use.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model LED light color device for detecting difference structural representation;
In figure: 1, pickup groove, 2, shadow shield, 3, prism, 4, color board, 5, LED lamp, 6, lead-in wire, 7, perforate, 8, rotating shaft, 9, universal bearing.
Embodiment
In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of LED light color device for detecting difference, comprise: be successively set on pickup groove 1, opaque shadow shield 2, prism 3 and color board 4 on support, pickup groove 1 is provided with positive and negative power supply lead-in wire 6, shadow shield 2 is provided with perforate 7, and perforate 7 is positioned on the line at pickup groove 1 and prism 3 middle parts, prism 3 two ends symmetries be provided with the rotating shaft 8 that can be rotatably connected on support, color board 4 is provided with some scale marks, and scale mark is parallel to the seamed edge of prism 3.Vitta after the direction of scale mark setting can ensure to be decomposed by prism 3 can be parallel with the perspective of scale mark to color board 4.
The xsect of the preferred prism 3 of the utility model is leg-of-mutton cylindricality prism 3, the prism 3 of cylindricality has excellent dispersion function, it can effectively change the direction of propagation of light interception of rays, and by the light of each color projecting on color board 4 successively, the situation that spacing is equal between all parts is little, the light composition that LED lamp sends differs, and projects the striation width difference of every kind of light on color board 4.
On shadow shield 2 in the horizontal direction or vertical direction be provided with multiple perforates 7, each perforate 7 is corresponding pickup groove 1, prism 3 and the color board 4 of being provided with all.
Symmetrically arranged rotating shaft 8 can flexible prism 3 with the angle of light source projects direction, also just can regulate ray cast after prism 3 reflects to position and angle on color board simultaneously.Color board 4 back sides are provided with universal bearing 9, and universal bearing 9 is fixedly connected on support, and universal bearing 9 can regulate the angular relationship of color board 4 and prism 3 flexibly, and can facilitate testing staff to observe comparison vitta width.
Perforate 7 is circle hole shape perforate 7 or the bar shaped perforate 7 that is parallel to fluting, in the time that light source is the less single light source of pointolite or area, adopt circle hole shape perforate 7, in the time that light source is bar shaped or plane, adopt bar shaped perforate 7, the selection of perforate 7 shapes can be mated light source form preferably, and light source is better projected on prism 3.Between multiple perforates 7, adopt opaque baffle interval, dividing plate is arranged on shadow shield and is positioned at pickup groove 1 one sides, and separated perforate 7 can be good at the interference of avoiding mutual between multiple light sources.
