Description

Technical Field

[0001] The utility model relates to the technical field of stage lamps, and more specifically to a lamp with an airtightness self-testing function. Background Art

[0002] In order to meet the needs of outdoor performances, there are more and more waterproof stage lights on the market. When leaving the factory or repairing, it is necessary to ensure that the air tightness test is OK. Conventional methods include water spraying test or inflating or exhausting the lamp body through other equipment (air tightness detection equipment), and observing the pressure change of the lamp body to determine whether the air tightness of the lamp body is OK. This causes great inconvenience to production and after-sales maintenance. Production requires testing of each connected device, and after-sales requires carrying an air tightness detection equipment with you, which is very time-consuming and labor-intensive. Utility Model Content

[0003] In order to overcome at least one defect of the prior art, the utility model provides a lamp with an airtightness self-testing function, which can realize the airtightness self-test of the lamp without the aid of external equipment, which is quick and convenient.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a lamp with an airtightness self-test function, including a lamp holder with a built-in light source, the light of the light source is emitted from the light outlet of the lamp holder, the lamp holder has a first closed cavity, and also includes a pump body for allowing gas to enter and / or discharge the first closed cavity and an air pressure sensor for detecting the air pressure in the first closed cavity.

[0005] The lamp with the airtightness self-test function inflates and / or exhausts the first closed cavity in the lamp holder through the built-in pump body, thereby changing the air pressure therein, and further detects the air pressure change in the first closed cavity through the air pressure sensor, thereby judging the airtightness performance of the first closed cavity, and completing the airtightness self-test, without the need to connect external devices one by one, and without the need to remove the lamp from the installation position, which is quick and convenient.

[0006] Furthermore, the light source is located in the first sealed cavity, so that even if the light source is not waterproof, it can still work normally.

[0007] Furthermore, an effect component for intercepting the light beam and changing the light effect is arranged in the first closed cavity. The effect component can make the light effect of the lamp more abundant, and the effect component is located in the first closed cavity, which can protect the effect component and prevent it from being contaminated or the related driving circuit from being damaged.

[0008] Furthermore, it also includes a support arm for supporting the rotation of the lamp head and a chassis for supporting the rotation of the support arm, so as to realize the rotation of the lamp head in two dimensions, so as to project the light of the light source in any direction.

[0009] Furthermore, a second sealed chamber for accommodating a switching power supply is provided in the chassis, and the second sealed chamber is communicated with the first sealed chamber. The second sealed chamber can protect the switching power supply, and the pump body cooperates with the air pressure sensor to realize the common sealing detection of the first sealed chamber and the second sealed chamber.

[0010] Furthermore, the pump body is arranged in the chassis and communicated with the second closed cavity to realize the inflation and / or exhaust of the first closed cavity. The space in the lamp holder is very compact, and the redundant space in the chassis is more than that in the lamp holder. Arranging the pump body in the chassis can save more space in the lamp holder.

[0011] Furthermore, the pump body allows gas to enter or discharge the first closed chamber in one direction, and the first closed chamber and the second closed chamber are connected to the outside world through a vent hole respectively, and each of the vent holes is opened and closed by a solenoid valve. After the air tightness test is completed, the two vent holes can speed up the gas exchange speed between the first closed chamber and the second closed chamber and the outside world, saving self-test time.

[0012] Furthermore, the pump body allows gas to enter or exit the first sealed chamber in one direction, and the first sealed chamber is also connected to the outside through a vent hole, and the vent hole is opened and closed by a solenoid valve. The first sealed chamber is also connected to the outside through the vent hole, and the vent hole is opened and closed by the solenoid valve. One of the pump body and the solenoid valve is for air intake, and the other is for air discharge, which reduces the requirements for the pump body, and it only needs to be able to achieve one-way air in and out.

[0013] Furthermore, a branch pipe is connected to the inner side of the air hole, which is connected to the electromagnetic valve and the pump body respectively, so as to reduce the number of openings on the first closed cavity and improve the sealing performance.

[0014] Furthermore, a waterproof breathable valve is provided on the channel connecting the pump body and / or the electromagnetic valve with the outside world. The waterproof breathable valve only allows air to enter and exit but rejects water droplets, thereby preventing water droplets from the outside from entering the interior of the lamp and affecting its normal operation.

[0015] Furthermore, a temperature sensor for detecting the ambient temperature is included. The temperature sensor can detect the ambient temperature, thereby judging whether it is suitable for the airtightness self-test, and avoiding inaccurate airtightness self-test due to too low or too high temperature.

[0051] There are many ways to self-test the air tightness of lamps, including but not limited to the following:

[0052] like Figure 6 , Option 1:

[0053] First, the temperature sensor 500 is used to detect whether the temperature inside the first closed chamber 130 is within a preset temperature range, and then the solenoid valve 410 is closed, and the pump body 140 starts to work (injecting gas into the first closed chamber 130 or exhausting gas from the first closed chamber 130). The change of the air pressure value inside the first closed chamber 130 is detected within a predetermined time to confirm whether the pressure difference change exceeds the preset threshold. If so, it is considered that the first closed chamber 130 has a good sealing performance. Otherwise, it is considered that the first closed chamber 130 has a poor sealing performance, and the result is fed back to the user (such as displayed on the lamp control panel or sent to the user remotely through the Internet of Things function). Finally, the airtightness self-test function is disabled to restore the lamp to normal use.

[0054] like Figure 7 , Option 2:

[0055] First, the temperature sensor 500 is used to detect whether the temperature inside the first closed chamber 130 is within a preset temperature range, and then the solenoid valve 410 is closed, and the pump body 140 starts to work (injecting gas into the first closed chamber 130 or exhausting gas from the first closed chamber 130) until the air pressure sensor 150 detects that the air pressure inside the first closed chamber 130 reaches a specified value, and then the pump body 140 is closed and maintained in this state. After a predetermined period of time, the air pressure in the first closed chamber 130 is detected again to confirm whether the pressure difference change exceeds the preset threshold. If not, it is considered that the first closed chamber 130 is well sealed. If so, it is considered that the first closed chamber 130 is poorly sealed, and the result is fed back to the user (such as displayed on the lamp control panel or sent to the user remotely through the Internet of Things function), and finally the airtightness self-test function is disabled to restore the lamp to normal use.

[0056] like Figure 8 , Option 3:

[0057] First, the temperature sensor 500 is used to detect whether the temperature inside the first closed chamber 130 is within a preset temperature range, and then the solenoid valve 410 is closed, and the pump body 140 starts to work (injecting gas into the first closed chamber 130 or exhausting gas from the first closed chamber 130). The air pressure inside the first closed chamber 130 is monitored over time within a predetermined time, and the rate of change of the air pressure over time is calculated to determine whether the rate of change of the air pressure over time is greater than a preset rate of change threshold. If so, it is considered that the first closed chamber 130 is well sealed. Otherwise, it is considered that the first closed chamber 130 is poorly sealed, and the result is fed back to the user (such as displayed on the lamp control panel or sent to the user remotely through the Internet of Things function). Finally, the airtightness self-test function is disabled to restore the lamp to normal use.
