Technical field
The present invention relates to the aberration testing tool, particularly relate to the luminous aberration of a kind of LED lamp bar and detect tool.
Background technology
Light emitting diode (LED) is owing to have a low power consuming, and long service life, characteristics such as volume is little, reaction is fast replace conventional bulb gradually and are applied in the various light-emitting devices, are wherein one of application as luminous LED lamp bar.The white light that LED lamp bar sends is synthetic by RGB, and RGB is a color of representing three passages of red, green, blue.Under the RGB pattern, every kind of RGB composition all can use from 0(black) to 255(white) value.When the value of all the components was 255, the result was a pure white, and when this value was 0, the result was an ater, and when R value 255, G value 0 and B value 0, the result is a shiny red.But present LED lamp bar is luminous, because light is too strong under the common visual situation, can't observe out the white light that LED lamp bar integral body or each several part send preferably and whether have aberration, can't carry out aberration to the white light that LED lamp bar is sent judges, so just can not carry out aberration to the LED lamp bar of producing and detect, can't guarantee the quality of LED lamp bar.
Summary of the invention
LED lamp bar sends white light in the prior art in order to solve, too strong owing to light under common visual situation, can't observe out white light that LED lamp bar integral body or each several part send preferably and whether have the problem of aberration, the invention provides the luminous aberration of a kind of LED lamp bar and detect tool, can observe out the white light that LED lamp bar sends easily and fast and whether have aberration.
In order to achieve the above object, the technical solution used in the present invention is:
The luminous aberration of a kind of LED lamp bar detects tool, comprise worktable, fixed head and loam cake, the place ahead at worktable is connected with fixed head, described fixed head one side and loam cake one side flexibly connect by two hinges, and loam cake and fixed head can be closed, it is characterized in that: the upper surface at fixed head is provided with boss, the madial wall of loam cake is provided with diffuser plate, described boss is identical with diffuser plate position relative size, be provided with the transverse concave groove that is used to place LED lamp bar at the middle part of boss, boss is provided with the breach that is communicated with the boss rear end face, and described breach is connected with the end of groove.
The luminous aberration of aforesaid a kind of LED lamp bar detects tool, and it is characterized in that: the madial wall of loam cake is provided with four layers of diffuser plate.
The luminous aberration of aforesaid a kind of LED lamp bar detects tool, it is characterized in that: spacing distance is 3mm between the diffuser plate of the described bottom and the second layer diffuser plate, described second layer diffuser plate and the 3rd layer of diffuser plate are close to and together mutually, and described the 3rd layer of diffuser plate and the 4th layer of diffuser plate are close to and together mutually.
The luminous aberration of aforesaid a kind of LED lamp bar detects tool, it is characterized in that: described diffuser plate adopts the two-sided light guide plate of pitted skin that is.
The luminous aberration of aforesaid a kind of LED lamp bar detects tool, and it is characterized in that: fixed head is provided with the locking jack, and loam cake is provided with the locking plug, and described locking jack is relative with the locking plug position, and the locking plug can insert in the locking jack.
The invention has the beneficial effects as follows: the present invention is positioned over LED lamp bar in the transverse concave groove of boss, LED lamp bar places the bottom of diffuser plate like this, after LED lamp bar energized is sent white light, white light spreads white light by the effect of diffuser plate, can find out clearly that like this there is aberration in which white light of partly sending of LED lamp bar, the technician can change or keep in repair the LED lamp of this part on the LED lamp bar targetedly after detecting and finishing, and has improved the quality of LED lamp bar.
Description of drawings
Fig. 1 is the structural representation that the luminous aberration of LED lamp bar of the present invention detects tool;
Fig. 2 is the structural representation of LED lamp bar of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing
At first introduce the structure of LED lamp bar down, as shown in Figure 1, a kind of LED lamp bar, comprise hard wiring board 1, flexible circuit board 2 and LED lamp 3, hard wiring board 1 is provided with several LED lamps 3, and the spacing distance of two adjacent LEDs lamp 3 equates that each LED lamp 3 is connected with the both positive and negative polarity pin of powering to this LED lamp 3, hard wiring board 1 one ends and flexible circuit board 2 one ends are welded to each other, and hard wiring board 1 is welded into rectangular-shaped with flexible circuit board 2.
As shown in Figure 2, the luminous aberration of a kind of LED lamp bar detects tool, comprises worktable 4, fixed head 5 and loam cake 6, is connected with fixed head 5 in the place ahead of worktable 4, fixed head 5 one sides and loam cake 6 one sides flexibly connect by two hinges 7, and loam cake 6 can be closed with fixed head 5.Simultaneously in order to make loam cake 6 and the fixed head 5 can be closed and locked, fixed head 5 is provided with locking jack 8, loam cake 6 is provided with locking plug 9, and locking jack 8 is relative with locking plug 9 positions, and locking plug 9 can insert in the locking jack 8 loam cake 6 and fixed head 5 are locked.Upper surface at fixed head 5 is provided with boss 10, the madial wall of loam cake 6 is provided with diffuser plate 11, boss 10 is identical with diffuser plate 11 position relative sizes, be provided with the transverse concave groove 12 that is used to place LED lamp bar at the middle part of boss 10, boss 10 is provided with the breach 13 that is connected with boss 10 rear end faces, and breach 13 is connected with the end of transverse concave groove 12.
