Because of long service life, the novel decorative board has the advantages of energy conservation, environmental protection and the like, and can gradually expose the corners in various decorative industries.
The existing LED strip needs to be subjected to an aging test to check whether the quality of the LED strip is qualified, for example, whether a power supply is stable in a high-temperature environment or not, and whether an LED is damaged in an assembly process or not. Generally, the strip aging test is performed by horizontally placing the LED strip on an aging table. The LED lamp strip aging test method has the following defects: 1. the LED lamp belts occupy large area, waste production space seriously, and occupy large area for the aging table, and because the LED lamp belts are long, the limited number of the LED lamp belts can be placed on the table top of one aging table. 2. The back of the LED lamp strip is tightly attached to the aging table, and the heat dissipation is poor, so that the aging result of the LED lamp strip is greatly influenced. 3. And an independent cooling system is required to be configured, so that the energy consumption is high. That is to say, the aging test of the LED strip generally needs to be performed in a special space with a temperature of 20 ℃ to 35 ℃ and a humidity of 55% to 95%, so that a separate cooling system needs to be configured, thereby increasing the power consumption.

In one embodiment, first hinge strap 121 and second hinge strap 131 are simultaneously telescoping for ease of manufacturing and control. Furthermore, the first hinge plate 12 and the second hinge plate 13 respectively extend and retract the first hinge strap 121 and the second hinge strap 131 on the plates in the same direction Z, which may be manually operated, for example, by a hand-operated hinge plate to control the extension and retraction of the hinge straps.
In an embodiment, as shown in fig. 2, the light strip aging test fixture 10 may further include a control unit 20. The control unit 20 is electrically connected to the power supply assembly 18 to obtain power. The control unit 20 controls the first hinge plate 12 and the second hinge plate 13 to extend and contract the first hinge strap 121 and the second hinge strap 131. Further, the control unit 20 includes a control board 201, and the control board 201 has a plurality of control buttons 202 thereon, which are electrically connected to the plurality of power supply sockets 17 in a one-to-one manner, that is, one control button 202 corresponds to one power supply socket 17, so as to control the corresponding light strip 11 to perform the burn-in test. When only need carry out aging testing to some lamp area 11, press corresponding control button 202 and can carry out aging testing, practice thrift the energy consumption.
Further, the lamp strip aging test fixture 10 may further include an upper limit sensor 21 and a lower limit sensor 22. The upper limit sensor 21 and the lower limit sensor 22 are used for sensing the positions of the first hinge strap 121 and the second hinge strap 131 and generating sensing signals to be transmitted to the control unit 20, and the control unit 20 controls the first hinge plate 12 and the second hinge plate 13 according to the sensing signals so that the first hinge strap 121 and the second hinge strap 131 are stretched. That is, the first hinge strap 121 and the second hinge strap 131 are limited in their stroke by the sensing of the upper limit sensor 21 and the lower limit sensor 22, and the expansion and contraction lengths of the first hinge strap 121 and the second hinge strap 131 are controlled.
To explain further, the sensing signal is generated by the upper limit sensor 21 and the lower limit sensor 22 according to the sensed positions of the first hinge strap 121 and the second hinge strap 131. The upper limit sensor 21 and the lower limit sensor 22 may be installed on a wall, or be erected from the ground, or hung from the ceiling.
In an embodiment, the surface of the lamp strip aging test rod 15 is provided with a heat-conducting insulating material, so that the heat dissipation capability of the lamp strip 11 during the aging test is enhanced.
In an embodiment, the two adjacent aging test bars 15 are spaced at equal intervals, so as to facilitate the aging test of the lamp strip 11. In addition, when the lamp strip 11 carries out the aging testing, leave the clearance between a plurality of lamp strip aging testing poles 15, be the setting of vertical arrangement, the circulation of air of can being convenient for to temperature when effectively reducing the aging testing just also need not to dispose independent cooling system, practices thrift the energy consumption.
In an embodiment, the lamp strip aging test rod 15 can adopt a widening design, so that a plurality of lamp strips 11 can be tested on one lamp strip aging test rod 15 at the same time, and the efficiency is improved.
Referring to fig. 3 and fig. 4, fig. 3 is a schematic structural view of a lamp strip aging test fixture 30 according to a second embodiment of the present invention when the lamp strip aging test fixture 30 is retracted, and fig. 4 is a schematic structural view of the lamp strip aging test fixture 30 according to the second embodiment of the present invention when the lamp strip aging test fixture 30 is extended. To achieve at least one of the advantages or other advantages, the second embodiment of the invention further provides a lamp strip aging test fixture 30 for performing an aging test on the lamp strip 11. Compared to the lamp strip aging test fixture 10 in the first embodiment, the lamp strip aging test fixture 30 in this embodiment is different only in that the lamp strip aging test rod 35 is made of a flexible material. Therefore, the light strip aging test rod 35 made of a flexible material does not need to be placed after the first hinge strap 121, the second hinge strap 131, the connection rod 14, and the fixing rod 16 form a frame capable of accommodating the light strip 11. In other words, as shown in fig. 3, when the strip weathering test fixture 30 is in the retracted state, the strip weathering test bar 35 made of flexible material may be retracted into the connecting rod 14.
And then, the automatic process of the aging test of the lamp strip 11 can be completed by arranging the control unit 20, the upper limit inductor 21 and the lower limit inductor 22.
In summary, with the lamp strip aging test fixtures 10 and 30 provided by the present invention, when the lamp strip 11 is to be subjected to an aging test, the first hinge belt 121 and the second hinge belt 131 extend outward to form a frame for placing the lamp strip 11, the lamp strip 11 is placed on the lamp strip aging test rods 15 and 35 for performing the aging test, and after the test is completed, the hinge belts are retracted inward, so that the production space can be effectively saved. In addition, the lamp strip aging test rod 15 can be made of metal materials, and a heat conduction insulating material is arranged on the surface of the lamp strip aging test rod, so that the heat dissipation problem is improved. Based on this, still can leave the clearance between a plurality of lamp area aging testing poles 15, when lamp area 11 carries out aging testing, a plurality of lamp area aging testing poles 15 vertical arrangement and have the clearance, the circulation of air of being convenient for to temperature when effectively reducing aging testing just also need not to dispose independent cooling system, practices thrift the energy consumption.
