Description
Technical field
The utility model relates to the LED lighting technical field, is specifically related to a kind of light guide plate and detects tool.
Background technology
The light guide plate that the LED lighting field is used generally adopts the acrylic of optical grade or PC to make, and materials has high reflectivity and the hitech materials of extinction not.And stamped some light guiding points at bottom surface of light guide plate with the UV screen printing technology, when the light that sends when the LED lamp was mapped to light guiding points, reflected light can toward all angles diffusion, then destroy conditioned reflex and penetrate by light guide plate is positive.By various densitys, light guiding points not of uniform size, the light that light guide plate is penetrated is even, soft.
Because light guide plate is one of Primary Component of LED lighting field, its technology content is also higher, general manufacturer production by specialty, and the light guide plate producer buying from specialty is all selected by general LED illumination producer.And if the light guide plate of purchasing is defective in quality, often can't when supplied materials, in time detects, and generally will could find in process of production.This is because can only check with finished product lamp assembling light guide plate now, thereby efficient is lower, can not check fast and efficiently supplied materials.Therefore the light guide plate detection tool that designs a kind of fast detecting light guide plate is very necessary.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of light guide plate and detects tool, and it can carry out fast supplied materials detection to light guide plate.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of light guide plate detects tool, and it comprises for detection of light guide plate: motherboard, lamp bar, lamp bar fixed block, reflective sheeting and diffuser plate; Described reflective sheeting is placed on the motherboard, and light guide plate to be measured is positioned on the reflective sheeting, and described diffuser plate overlays again on the light guide plate; Described lamp bar is arranged on the motherboard by lamp bar fixed block, and abuts against at least one side of the described reflective sheeting, light guide plate and the diffuser plate that are stacked together.
In the preferred technical scheme, described lamp bar has two, respectively is fixed on the described motherboard by a described lamp bar fixed block, and is positioned at the two opposite sides of light guide plate.
In the preferred technical scheme, described lamp bar has four, respectively is fixed on the described motherboard by a described lamp bar fixed block, and is positioned at four sides, upper and lower, left and right of light guide plate.
In the further preferred technical scheme, be provided with screw hole on the described motherboard, described lamp bar fixed block cooperates described screw hole to be fixedly installed on the motherboard by screw.
Further in the preferred technical scheme, the screw hole on the described motherboard has several, and it can cooperate lamp bar and the lamp bar fixed block of plurality of specifications, surrounds the surveyed area of a plurality of dimensions at motherboard, to adapt to the light guide plate of sizes specification.
The beneficial effects of the utility model are:
Owing to there has been light guide plate of the present utility model to detect tool, can detect fast light guide plate, when detecting, supplied materials just can find the mass defect of light guide plate, thus improving production efficiency, and save production cost.And simple, with low cost, the reliable operation of this light guide plate detection jig structure, have very high practicality.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is the vertical view that the utility model embodiment light guide plate detects tool;
Fig. 2 is the cut-open view of A-A section among Fig. 1;
Fig. 3 is the vertical view that the utility model embodiment light guide plate detects motherboard in the tool.
Embodiment
A kind of light guide plate that this embodiment provides detects tool, and it is used for fast detecting light guide plate 20.This light guide plate detects tool as depicted in figs. 1 and 2, comprising: motherboard 11, lamp bar 13, lamp bar fixed block 12, reflective sheeting 14 and diffuser plate 15; Described reflective sheeting 14 is placed on the motherboard 11, and light guide plate 20 to be measured is positioned on the reflective sheeting 14, and described diffuser plate 15 overlays again on the light guide plate 20; Described lamp bar 13 is arranged on the motherboard 11 by lamp bar fixed block 12, and abuts against at least one side of the described reflective sheeting 14, light guide plate 20 and the diffuser plate 15 that are stacked together.Certainly, LED lamp 131 on the lamp bar 13 will be towards light guide plate 20, so as with its ray cast of sending in light guide plate 20, decline light is through after the reflection of reflective sheeting 14, so that most of light from the upper surface ejaculation of light guide plate 20, finally passes through the upper surface ejaculation of diffuser plate 15.Need to prove that the electrode on the lamp bar 13 is connected with switch and power supply by wire, for lamp bar 13 provides electric power supply, not shown.Lamp bar fixed block 12 adopts the aluminium in zigzag cross sections, perhaps the aluminum strip bending is gone out the zigzag cross section, and the appropriate location is stamped the hole of passing through for screw 16 and got final product thereon again.
Owing to there has been the light guide plate of this embodiment to detect tool, can detect fast light guide plate 20, when detecting, supplied materials just can find the mass defect of light guide plate 20, thus improving production efficiency, and save production cost.And simple, with low cost, the reliable operation of this light guide plate detection jig structure, have very high practicality.
In the preferred technical scheme, described lamp bar 13 has two, respectively is fixed on the described motherboard 11 by a described lamp bar fixed block 12, and is positioned at the two opposite sides of light guide plate 20.Because for the light guide plate 20 of some specification, as long as it is just passable that lamp bar 13 is set in its two opposite sides.
In the preferred technical scheme, described lamp bar 13 has four, respectively is fixed on the described motherboard 11 by a described lamp bar fixed block 12, and is positioned at four sides, upper and lower, left and right of light guide plate 20.Because for the light guide plate 20 of some specification, its all around four direction a lamp bar 13 respectively is set.
In the further preferred technical scheme, be provided with screw hole 111 on the described motherboard 11, described lamp bar fixed block 12 cooperates described screw hole 111 to be fixedly installed on the motherboard 11 by screw 16.
