Abstract
The utility model relates to a liquid crystal module group and particularly to a light bar aging tool of the liquid crystal module group, and the tool can be used for simulating aging test on a whole liquid crystal television. An LED light bar aging tool includes a substrate, a driving power supply and a heat dissipating plate, and the driving power supply and the heat dissipating plate are fixed on the substrate; the substrate is provided with a plurality of fixing holes, the fixing holes are arranged in two rows in a one-to-one correspondence mode, the fixing holes in each of the rows are arranged at an equal distance, and the distance between the two rows of the fixing holes is consistent with that of an LED lighting bar to be tested; and the heat dissipating plate is arranged between the two rows of the fixing holes. The above structure is adopted by the LED light bar aging tool, an aging test is only carried on light bars of the most key device of a liquid crystal television, an actual temperature of the whole television can be simulated by adjusting the distance between the light bars, reliability of the light bars can be very conveniently and accurately verified, and the test space is saved.
Description
Technical field
The utility model relates to liquid crystal module field, refers more particularly to the lamp bar aging equipment in a kind of liquid crystal module, can simulate liquid crystal whole set of television and carry out aging.
Background technology
At present, the LED-backlit in LCD TV because the advantage of energy-saving and environmental protection to have substituted rapidly traditional CCFL backlight, in LED-backlit side light type LED back light with and appearance is slim, cheap has occupied the most market share in LED-backlit.But because LED belongs to heater members, side-light type LED is because LED device is concentrated, heat density is large, so the working temperature of LED is higher, and LED belongs to semiconductor devices, and higher temperature can cause LED life-span and large shortening, has affected the reliability of product.In order understanding, to guarantee tv product reliability, before TV dispatches from the factory, can to carry out the aging checking of complete machine and guarantee product quality, but complete machine is aging in a large number, extremely take up room and place.
Utility model content
The purpose of this utility model is for the problems referred to above, provides a kind of LED lamp bar aging frock, carries out agingly for the Primary Component lamp bar of LCD TV, saves space.
In order to achieve the above object, the utility model is by the following technical solutions:
The aging frock of a kind of LED lamp bar, it is characterized in that: the aging frock of described LED lamp bar comprises substrate, driving power, heat sink, described driving power and heat sink are fixed on substrate, substrate is provided with several fixed orifices, described fixed orifice is arranged in two row one to one, the fixed orifice often listing is equidistantly arranged, consistent with on LED lamp bar to be measured of the distance between two row fixed orifices, and heat sink is located between two row fixed orifices.
Further, described driving power quantity is one or more, and the quantity of power drives plate can be adjusted according to the different designs test quantity of the aging frock of lamp bar.
Further, described heat sink is aluminum plate, or is beneficial to the other materials that coefficient of heat conductivity is high.
The utility model adopts said structure, only for the device light bar of most critical in LCD TV, carries out agingly, can simulate complete machine actual temperature by adjusting lamp stripe pitch, very convenient and verify accurately the reliability of lamp bar, the saving test space.
Accompanying drawing explanation
Fig. 1 is the utility model working state schematic representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail, but not as to restriction of the present utility model.
As shown in Figure 1, the aging frock of a kind of LED lamp bar, the aging frock of described LED lamp bar comprises substrate 1, driving power 2, heat sink 3, described driving power 2 and heat sink 3 are fixed on substrate 1, substrate 1 is provided with several fixed orifices 4, and described fixed orifice 4 is arranged in two row one to one, and the fixed orifice 4 often listing is equidistantly arranged, consistent with on LED lamp bar 5 to be measured of distance between two row fixed orifices 4, heat sink 3 is located between two row fixed orifices 4.
The utility model adopts said structure, only for the device light bar of most critical in LCD TV, carries out agingly, can simulate complete machine actual temperature by adjusting lamp stripe pitch, very convenient and verify accurately the reliability of lamp bar, the saving test space.
Below the utility model is described in detail, but apparent, those skilled in the art can carry out various changes and improvements, and does not deviate from the scope of the present utility model that appended claims limits.
