Description

TECHNICAL FIELD

[0001] The utility model relates to lighting lamps and lanterns technical field, more specifically, it relates to a lighting lamps and lanterns with dust accumulation detection function. BACKGROUND

[0002] The lighting lamps and lanterns used in stage are a kind of high-power lamps and lanterns, and the heat release is very large. In order to quickly dissipate heat, the lighting lamps and lanterns are usually communicated with the outside, and the air outside is used to dissipate heat for the lighting lamps and lanterns. However, dust in the air can adhere to optical devices inside the lighting lamps and lanterns, affecting the light efficiency, and can also adhere to electronic devices, possibly causing short circuit of the electronic devices. Therefore, a dust filter screen is needed to filter dust in the air. With the increase of use time, the dust filter screen can be blocked by dust, resulting in reduced ventilation effect. Since the dust filter screen is blocked, the heat in the lighting lamps and lanterns cannot be dissipated in time, affecting the performance of the lamps and lanterns. SUMMARY

[0003] The utility model provides a lighting lamps and lanterns with dust accumulation detection function to overcome at least one of the defects of the prior art, which can monitor the blockage state of the dust filter screen in time.

[0004] To solve the above technical problems, the utility model adopts the technical scheme of a lighting lamps and lanterns with dust accumulation detection function, which has an air inlet for communicating the lighting lamps and lanterns with the outside and a dust filter screen located at the air inlet. The utility model further comprises a heat dissipation fan for promoting outside air to enter the inside of the lighting lamps and lanterns through the dust filter screen at the air inlet, and a detector for detecting the dust accumulation degree of the dust filter screen.

[0005] The lighting lamps and lanterns with dust accumulation detection function are communicated with the outside through the air inlet to improve the heat dissipation capacity, and the dust filter screen is used to prevent dust from entering the inside of the lighting lamps and lanterns. The detector for detecting the dust accumulation degree of the dust filter screen is further included to monitor the blockage state of the dust filter screen. Therefore, automatic dust removal operation can be performed, or the user is reminded to remove dust from or replace the dust filter screen to maintain the lighting lamps and lanterns in the best working state.

[0006] Further, the detector is a wind speed sensor, a wind volume sensor or a wind pressure sensor. By detecting the airflow condition entering the inside of the lighting device, the blockage state of the dust filter screen can be determined.

[0007] Further, the detector is located inside the lighting lamps and lanterns to detect the air flowing through the dust filter screen. The influence of strong airflow (such as strong wind weather) in the external environment on the detector can be effectively reduced.

[0008] Further, the detector is located at the middle of the air inlet. After the air flowing through the air inlet is filtered by the dustproof filter screen, the middle of the dustproof filter screen is generally the least dust accumulation position, so the air flow condition at this position is directly detected, and the result is more accurate.

[0009] Further, the detector is two temperature sensors for detecting the internal temperature of the lighting fixture and the external environment temperature respectively. By detecting the temperature difference between the inside and outside of the lighting device, in combination with the power of the heat dissipation device and the lighting device (if necessary, the pre-stored data can be compared), the clogging state of the dustproof filter screen can be indirectly judged.

[0010] Further, the detector is two pressure sensors for detecting the internal pressure of the lighting fixture and the external environment pressure respectively. By detecting the pressure difference between the inside and outside of the lighting device, in combination with the power of the heat dissipation fan (if necessary, the pre-stored data can be compared), the clogging state of the dustproof filter screen can be indirectly judged.

[0011] Further, it further includes an exhaust port for communicating the lighting fixture with the outside, and the heat dissipation fan is located at the exhaust port. The exhaust port can accelerate the gas exchange between the lighting fixture and the outside, accelerate heat dissipation, and the heat dissipation fan located at the exhaust port can make the heat dissipation fan better perform.

[0012] Further, the dustproof filter screen is a waterproof and breathable cloth. The waterproof and breathable cloth can not only allow air to pass freely, but also can prevent water from entering the inside of the lighting fixture, thereby improving the waterproof performance of the lighting fixture.

[0013] Further, the lighting fixture has a lamp holder for accommodating a light source, a support arm supporting the rotation of the lamp holder, and a case supporting the rotation of the support arm. Through the support of the support arm and the case, the lamp holder can be arbitrarily rotated, so that the light beam emitted by the light source can be projected in any direction.

[0014] Further, the air entering from the air inlet flows through the lamp holder of the lighting fixture for accommodating the light source to heat the light source. The air inlet can be located at any position of the lighting fixture, as long as the air entering from the air inlet can finally flow through the lamp holder of the lighting fixture for accommodating the light source to heat the light source.

[0015] Further, the air inlet is arranged on the shell of the lamp holder and corresponds to the light source. In this way, the air entering from the air inlet can directly and quickly heat the light source.

[0016] Further, the lamp cap is divided into a sealed first chamber and a second chamber communicating with the outside, the light source is located in the first chamber, a heat sink for dissipating heat of the light source is arranged in the second chamber, the first chamber and the second chamber are communicated through an exhaust port, and air in the first chamber is discharged after flowing through the second chamber through the exhaust port. The exhaust port is hidden in the second chamber, so that rainwater is prevented from entering the lighting lamp from the exhaust port, and the lighting lamp looks more beautiful.

[0027] In the preferred embodiment of the utility model, the detector 180 is a wind speed sensor, a wind volume sensor or a wind pressure sensor. By detecting the airflow condition entering the inside of the lighting device, the jamming state of the dust filter screen 120 can be determined.

[0028] The wind speed sensor, the wind volume sensor or the wind pressure sensor respectively detects the speed of the wind, the air volume passing through a certain section per unit time and the pressure difference generated by the air flow.

[0029] In the preferred embodiment of the utility model, the detector 180 is located inside the lighting lamp to detect the air after flowing through the dust filter screen 120. The influence of strong airflow (such as windy weather) in the external environment on the detector 180 can be effectively reduced.

[0030] If necessary, a wind guide channel can be arranged at the air inlet 110, and the detector 180 is arranged in the wind guide channel to better perform measurement.

[0031] In the preferred embodiment of the utility model, the detector 180 is located at the middle position of the air inlet 110. After the dust filter screen 120 filters the air flowing through the air inlet 110, generally the middle position of the dust filter screen 120 has the least dust accumulation, so the airflow condition at this position is directly detected, and the result is more accurate.

If the dustproof filter screen 120 has too much dust, so that the external air cannot enter the inside of the lighting lamp smoothly, the air pressure in the inside of the lighting lamp will be lower than that of the outside.

[0036] In the preferred embodiment of the utility model, it also includes an exhaust port 140 for connecting the lighting lamp with the outside, and the heat dissipation fan 130 is located at the exhaust port 140.
