Description

Technical Field

[0001] The utility model relates to the technical field of non-destructive testing equipment, in particular to a dual-mode LED film viewing lamp for non-destructive testing. Background Art

[0002] LED film viewing lamp is a lighting device that uses LED as a light source. It is widely used in the field of non-destructive testing to help technicians check for defects inside or on the surface of materials, components, and equipment, such as cracks, impurities, pores, etc. These defects will affect the integrity and safety of materials, components, and equipment. Traditional LED film viewing lamps have some problems, such as: 1. Different occasions have different requirements for the brightness of the LED, so it needs to be adjusted frequently. The adjustment switch is exposed and it is easy to touch it by mistake during use, resulting in undue changes in brightness; 2. The LED film viewing lamp generates heat during operation. Traditional LED film viewing lamps only dissipate heat physically through heat dissipation holes, which has poor heat dissipation effect and is prone to malfunction; 3. The strength is limited, especially the edge positions are easily damaged. The combination of the above problems will affect the stability of the LED film viewing lamp's working process and ultimately affect the accuracy of the detection results. Based on this situation, how to ensure the stability of the LED film viewing lamp's working process has become an increasingly urgent problem that relevant technicians need to solve.

An LED light board is fixedly arranged inside the main body 4, and the LED light board is located directly behind the observation screen 2. A power switch 7, a brightness adjustment switch 6, and a foot pedal conversion switch 8 are arranged at the lower part of the main body 4, and a first socket 13 and a second socket 15 are fixedly arranged on the upper part of the right vertical plate 5. The first socket 13 is a power socket, and the second socket 15 is a foot pedal socket. A main board is arranged inside the main body 4, and the power switch 7, brightness adjustment switch 6, foot pedal conversion switch 8, first socket 13, and second socket 15 are all electrically connected to the main board.

[0025] Furthermore, a left heat dissipation hole 16 is provided through the center position of the left vertical plate 1, a right heat dissipation hole 14 is provided through the center position of the right vertical plate 5, a rear heat dissipation hole 9 is provided through the rear part of the main body 4, and fans 17 are provided at positions corresponding to the left heat dissipation hole 16, the right heat dissipation hole 14, and the rear heat dissipation hole 9 inside the main body 4, and the fan 17 is electrically connected to the main board.

[0026] Furthermore, an isolation net 11 is fixedly provided outside the left heat dissipation hole 16 , the right heat dissipation hole 14 , and the rear heat dissipation hole 9 .

[0027] Furthermore, mounting seats 10 are symmetrically fixedly provided at the rear of the main body 4 , and a support frame 12 is provided between the mounting seats 10 . The support frame 12 is U-shaped, and the end of the support frame 12 is connected to the mounting seats 10 in a damped rotation manner.

[0028] Furthermore, the protective pads 3 are fixedly provided at the front and rear edge positions of the main body 4, and the front and rear edge positions of the main body 4 and the protective pads 3 are all rounded.

[0029] Furthermore, the maximum observable black value of this LED film viewing lamp is not less than 5.0D, and the maximum brightness is not less than 320000Cd / m 2 , the uniformity coefficient is not less than 0.2, and the scattering coefficient is not less than 0.5.

[0030] The working principle of a dual-mode LED film viewing lamp for non-destructive testing of the present invention is as follows: rotate the support frame 12 to a suitable angle, such as the commonly used elevation angle of 30 degrees, and place the LED film viewing lamp stably in the working position through the left vertical plate 1, the right vertical plate 5, and the support frame 12, and connect the corresponding power supply at the first socket 13 and the second socket 15 respectively, long press the power switch 7, the LED light board is powered on and lights up, short press the power switch 7, and switch the lighting area of ​​the observation screen 2 according to actual needs, such as making it all light up, and the observation screen 2 evenly scatters the light of the LED light board, so that a suitable light source can be provided for film viewing. When the brightness needs to be adjusted, long press the brightness adjustment switch 6 to increase the brightness. If the brightness accidentally exceeds expectations, long press the brightness adjustment switch 6 again to reduce the brightness, and so on. Fine-tuning can be completed. The user can also press the foot switch 8 first, and then long press the brightness adjustment switch 6 to pre-adjust the brightness. Press the foot switch 8 again to enter the foot mode. In this mode, when the foot switch 8 is not pressed, the observation screen 2 position displays a darker basic brightness. When the foot switch 8 is pressed, the observation screen 2 position displays the pre-adjusted brightness, so as to avoid accidentally touching the brightness adjustment switch 6 and causing undue changes in brightness. At the same time, the basic brightness can achieve a certain degree of energy-saving effect. The built-in program of the main board enables the fan 17 to automatically start when the temperature of the LED viewing lamp is higher than the set value. The left heat dissipation hole 16, the right heat dissipation hole 14, and the rear heat dissipation hole 9 are combined with the fan 17 to blow air outwards for continuous heat dissipation. The fan 17 automatically turns off when the temperature of the LED viewing lamp is lower than the set value.

Any changes or substitutions that do not require creative work should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
