TECHNICAL FIELD
[0001] The utility model relates to stage lamp technical field more specifically, it is a kind of lamp dehumidification system. BACKGROUND
[0002] Current market stage lamp although widely adopts IP65 level waterproof shell, but in actual use, moisture still cannot avoid seeping into inside lamp cavity.For example, when high-power light source runs, lamp cavity temperature can soar to 100 DEG C or more, and after show ends equipment sudden stop, temperature will quickly drop to about 40 DEG C.This sharp temperature difference change can form negative pressure in lamp cavity, like "suction tube" as if the external humid air is sucked into inside.Surface will quickly condense fog even water droplet when humid air contacts low-temperature lens glass or metal heat sink.If there is a large amount of water vapor in lamp cavity, not only lens is covered with white spots, distorts light pattern, and if electronic components in lamp cavity work in high humidity environment for a long time, it can seriously affect service life.
[0003] Industry commonly used "drying agent" scheme needs to open lamp cavity regularly to replace consumables, and maintenance cost is high, and heating dehumidification method can temporarily achieve lens demisting effect, but can cause lamp to extra consume 5-8% electricity, even interfere with reading accuracy of temperature sensor.For the touring lamps (such as from high-temperature stage to low-temperature warehouse) needing to be frequently moved and experiencing sharp temperature and humidity fluctuations, both methods are like "adhesive tape" as if difficult to solve problems, and industry urgently needs a flexible and versatile dehumidification scheme. UTILITY MODEL CONTENT
[0004] The utility model provides a lamp dehumidification system to overcome at least one of the defects of the prior art, by connecting the gas-liquid separation device, effectively reduce the humidity inside the stage lamp cavity.
[0005] To solve the above technical problems, the utility model adopts the technical scheme: provide a kind of lamp dehumidification system, including lamp body, with the lamp head for generating light beam and the support seat for supporting the rotation of the lamp head, the lamp head and / or the support seat are formed with sealed cavity;Gas-liquid separation device is located outside the lamp body, the gas-liquid separation device extracts the gas inside the cavity after drying, then is transported back inside the cavity, forms circulation.
[0006] The gas-liquid separation device is externally connected, and the gas in the sealed cavity is extracted, dried, and then transported into the cavity again. After several such cycles, the humidity of the gas in the cavity can be effectively reduced. The present scheme breaks the limitations of traditional passive adsorption or heating dehumidification, and is more flexible in operation, and avoids the additional high temperature caused by heating and dehumidifying. The gas-liquid separation device is independent of the lamp body and can be maintained separately without affecting the function of the lamp body. At the same time, it does not occupy the installation space inside the lamp body, and can be compatible with various types of lamps. In addition, the circulating drying mechanism can quickly balance the temperature difference of the cavity caused by the start and stop of the lamp body, effectively alleviate the negative pressure moisture absorption phenomenon, and can adapt to frequent temperature changes. It has strong versatility.
[0007] When the lamp is shipped, the lamp body is initially dehumidified by the gas-liquid separation device, and the cavity is resealed to keep the inside of the lamp body dry. When the lamp is used up, the light source stops heating, the temperature in the cavity changes dramatically, forming a negative pressure, and the humidity outside is absorbed into the cavity along with the gas. At this time, the gas-liquid separation device is used to extract the gas in the cavity for circulating dehumidification and drying, and finally a stable dry environment is formed in the cavity. The gas-liquid separation device can be removed after completing the work, which is convenient for storage. When the detection system in the lamp prompts that the humidity is too high, the gas-liquid separation device can also be used for dehumidification, which is suitable for various scenes.
[0008] Further, the gas-liquid separation device includes a condensing unit for condensing, a separation unit for separating water from the condensed gas-liquid mixture, and an air flow driving mechanism for driving the gas to flow sequentially between the cavity, the condensing unit, and the separation unit.

Finally, the dry gas is transported back into the cavity, and several cycles are performed according to the requirements to make the cavity reach the ideal humidity. Through the synergistic effect of condensation-separation and circulating air flow design, the drying efficiency and reliability are improved.
[0009] Further, the condensing unit includes a condensing cavity for condensing and a refrigeration sheet for cooling the condensing cavity. The refrigeration sheet and the condensing cavity cooperate to continuously cool the condensing cavity, so that the water vapor in the humid hot gas flowing through the condensing cavity is condensed.
[0010] Further, the condensing unit further includes a cover body covering the refrigeration sheet, the cover body is buckled on the refrigeration sheet and forms the condensing cavity together, and the refrigeration sheet is provided with cooling fins.

The humid hot air enters the condensing cavity through at least two paths, so that the airflows are blown more uniformly to all parts of the condensing cavity, thereby improving the heat exchange efficiency.
[0012] Further, the separation unit is a pressure regulating filter or a membrane dryer or an adsorption dryer. The type of separation device can be selected as needed, the pressure regulating filter is suitable for high-flow working environment, the combination of pressure reducing valve and inertial separation structure can expand the volume and reduce the pressure when the airflow passes at high speed, so as to promote the condensation and interception of water vapor; the membrane dryer can selectively permeate water molecules and directly discharge water vapor under the driving of air pressure, without the need to increase moving parts, thereby effectively reducing the energy consumption of the gas-liquid separation device; the adsorption dryer is suitable for ultra-low dew point scenes and has high reliability.
[0013] Further, a heating device is further included, which heats the gas output by the gas-liquid separation device and then inputs the gas into the cavity. The gas heated by the heating device is re-input into the cavity to heat other gases in the cavity, so that the gas mixed with water vapor becomes humid hot gas, which is extracted by the gas-liquid separation device for the next cycle. The heating device can avoid the situation that the temperature of the lamp body drops rapidly due to stopping working, so as to make the air pressure in the cavity more stable.
[0014] Further, the gas-liquid separation device further includes a sensor for detecting the temperature and / or humidity of the gas, which is arranged at the gas inlet and / or gas outlet of the gas-liquid separation device. By arranging the sensor, the temperature and / or humidity of the gas in the cavity can be more intuitively observed and more accurately controlled.
[0015] Further, the cavity in the lamp head and the cavity in the support seat are in communication with each other, and the cavity is connected with the gas-liquid separation device through air permeable holes, one of which is arranged on the lamp head and the other of which is arranged on the support seat. The gas-liquid separation device works after being connected with the cavity through the air permeable holes, the gas in the cavity is extracted from the lamp head and then dehumidified by the gas-liquid separation device, the dried gas is transported from the air permeable holes to the support seat, and the gas in the lamp body flows from the support seat to the lamp head, thereby forming a cycle.
