Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of explosion-proof lighting devices, in particular to an industrial self-adaptive explosion-proof floodlight. BACKGROUND

[0002] The explosion-proof floodlight is used to provide safe and reliable lighting in explosive hazardous environments to reduce the occurrence of fire or explosion accidents. In dangerous environments such as oil and flour mills, there are flammable and explosive substances, so special designed explosion-proof equipment must be used. Such a lamp has the characteristics of explosion-proof, waterproof, corrosion-resistant, etc., which can improve work efficiency and improve the working environment, and provide more comfortable and bright light for workers.

[0003] When the temperature inside the floodlight increases, the brightness of the floodlight will decrease, which is the most common light decay effect. The existing LED floodlight is usually an LED lamp. Because of the harsh working environment, the influence of temperature will be more significant. For example, in a high temperature environment, the electronic components inside the lamp may be damaged or fail, resulting in a decrease in brightness or complete failure of the lamp. In addition, in a high temperature environment, the heat dissipation capacity of the lamp will be affected, thereby affecting the brightness and life of the lamp.

[0004] For mines or flour mills, explosion-proof floodlights are generally required to work for a long time, so the temperature inside the floodlight will become higher and higher. As the temperature of the floodlight increases, the light emitted by the floodlight will suddenly become dim, which will easily affect the workers working under the light, thereby affecting the visibility of the workers. In addition, workers working in such a dim environment for a long time will cause eye congestion, which will cause discomfort and eye fatigue, thereby affecting the overall work efficiency.

[0005] In view of this, in view of the above-mentioned problems, the present application develops an industrial self-adaptive explosion-proof floodlight. SUMMARY

[0006] The technical problem to be solved by the present application is that the existing explosion-proof floodlight mostly uses LED beads. Because of the high internal temperature, light decay phenomenon occurs, which causes the brightness to suddenly decrease, thereby affecting the workers working under the light and reducing the work efficiency.

[0007] The application provides the following technical scheme: an industrial self-adaptive explosion-proof floodlight, comprising a shell, a lamp tube and a lampshade, the shell is fixedly installed on a lamp holder, the lamp tube is fixedly installed inside the shell, and the lampshade is fixedly installed on the shell; an adjusting mechanism is slidably installed inside the shell, the adjusting mechanism is used for automatically supplementing light in the floodlight according to the increase of the temperature of the lamp tube, so as to ensure that the brightness of the floodlight is always constant; a dust removal mechanism is fixedly installed on the left side of the lampshade, the dust removal mechanism is used for cooperating with the adjusting mechanism to automatically clean dust on the surface of the lampshade; a heat dissipation mechanism is fixedly installed inside the shell, and the heat dissipation mechanism is used for reducing the temperature of the surface of the floodlight and cooperating with the adjusting mechanism to make the temperature inside the lampshade tend to be stable.

[0008] When the temperature in the floodlight starts to rise, the brightness of the floodlight will decrease, for example, the working range of the explosion-proof floodlight with a rated power of 100W is usually between 60 DEG C and 80 DEG C, during the process of the increase of the working temperature, the adjusting mechanism will correct the brightness in the floodlight according to the temperature in the lampshade, that is, when the brightness of the floodlight is reduced due to the excessively high temperature, the adjusting mechanism will open the side light supplementing lamp to correct the brightness of the floodlight according to the temperature, in this way, the brightness of the floodlight can always be in a stable state.

[0009] When the temperature in the lampshade is excessively high, the adjusting mechanism will correct the light in the lampshade according to the temperature, and the heat dissipation unit will also dissipate heat from the floodlight through water cooling, the heat in the floodlight is exchanged through the cooling water, and then the heat is discharged to the air through the heat dissipation fins, so that the temperature in the lampshade is always in a stable state, and the illumination effect in the floodlight is always stable without sudden dimming or variation in the cooperation with the adjusting mechanism.

[0010] It should be noted that, since the explosion-proof floodlight is usually used in mine, oil exploration or flour mill and the like, a lot of dust will appear on the lampshade, and the dust cannot be cleaned in time due to the high position of part of the explosion-proof floodlight, so that the dust accumulated on the surface of the lampshade for a long time will block the light and affect the illumination effect; therefore, the dust removal mechanism is installed on one side of the lampshade, and the air flow is blown to form an air wall to prevent the dust from falling on the lampshade, compared with the traditional manual wiping, the air wall isolation method can minimize the damage to the lampshade of the floodlight, thereby prolonging the service life of the floodlight.

[0011] The adjusting mechanism comprises an adjusting groove, a cooling strip, an adjusting rod, a temperature sensor, an adjusting slider, a light transmission lens, a light supplement lamp and a conductive sheet, the adjusting groove is embedded in the shell, one end of the adjusting groove is fixedly installed with the adjusting rod, and the adjusting rod is fixedly installed with the adjusting slider; the temperature sensor is fixedly installed in the shell and is used for detecting the temperature in the shell and pushing the adjusting slider forward to increase the contact area of the high-temperature gas and the cooling strip to reduce the temperature in the shell; the light transmission lens is fixedly installed between the adjusting sliders and is used for refracting the light emitted by the lamp tube to the lampshade; the light supplement lamp is fixedly installed in the adjusting groove and is used for supplementing light in the lamp tube when the brightness of the lamp tube is reduced due to high temperature, so that the illumination effect outside is kept stable; the conductive sheets are fixedly installed on the adjusting sliders and the adjusting groove, and the conductive sheets are used for contacting each other with the movement of the adjusting sliders to turn on the light supplement lamp.

[0012] Based on the scheme, when the temperature in the floodlight increases, the adjusting rod in the adjusting groove will extend, the extended adjusting rod drives the adjusting slider to move, the moving adjusting slider drives the light transmission lens to move forward, and the conductive sheet on the slider contacts the conductive sheet on the adjusting groove to turn on the switch of the light supplement lamp, so that the light supplement lamp is turned on to correct the brightness in the floodlight.

[0013] It should be noted that, since the temperature in the floodlight is continuously increasing, the light supplement lamp is provided as two groups, in this way, when the temperature increases and the first group of light supplement lamps is turned on for a long time, the temperature in the floodlight has not decreased, at this time, the adjusting rod will move forward again, at this time, the second group of light supplement lamps will also be turned on to correct the brightness of the floodlight again, and then the two correction times completely meet the needs of ensuring the brightness of the floodlight under the working of the heat dissipation mechanism, and when the temperature decreases, the adjusting rod is retracted to drive the adjusting slider to move backward to turn off the light supplement lamps.

[0014] The light supplement lamp is inclined at an angle of 45° in the shell, and a reflecting sheet is fixedly installed in the shell, the reflecting sheet is used for receiving the light emitted by the light supplement lamp and reflecting it to the lampshade; the inclination angle of the light supplement lamp is set to 45° to obtain the maximum illumination area, after the light emitted by the light supplement lamp is irradiated on the reflecting sheet, the reflecting sheet irradiates the light emitted by the light supplement lamp to the lampshade to correct the illumination in the floodlight;

[0015] In the process of correcting the brightness by the light supplement lamp, the brightness of the original LED is further reduced due to the further temperature rise, so the process of the light supplement lamp should not be suddenly turned on to the brightest state, but gradually open the small lamp beads inside the light supplement lamp according to the area of the contact of the conductive sheet to achieve a slow brightening effect, which can make the correction of the light supplement lamp more natural and soft, and will not affect the production.

[0016] The dust removal mechanism includes a dust removal shell, a dust removal motor, a uniform air nozzle, a dust removal air suction pipe and a filter screen, the dust removal shell is fixedly installed on one side of the shell, and the dust removal shell is used for gas flow while preventing the dust removal motor inside; the dust removal shell is L-shaped, and the dust removal motor is fixedly installed inside the dust removal shell; the dust removal motor is used to provide power for the dust removal mechanism; the dust removal shell is arranged in an L shape to be attached to the side of the explosion-proof floodlight, so that the dust removal mechanism is more stably fixed on the side of the floodlight and can better remove dust on the lampshade; the output end of the dust removal motor is fixedly installed with the uniform air nozzle, and the uniform air nozzle is used to uniformly spray air to form an air wall; the input end of the dust removal motor is fixedly installed with the dust removal air suction pipe, and the air suction pipe is used to cooperate with the dust removal motor to suck air through the dust removal air suction pipe and spray air through the uniform air nozzle, thereby realizing the dust removal effect on the surface of the lampshade; the filter screen is fixedly installed inside the dust removal air suction pipe; the filter screen is used to isolate dust in the air outside the dust removal shell, prevent dust from entering the dust removal shell, and thereby affect the dust removal effect of the dust removal mechanism;

[0017] When the dust removal mechanism works, because dust floats in the air, the longer the lamp is used, the more dust adheres to the lampshade, so under the long-time adhesion of dust, the dust affects the light transmittance of the lampshade, thereby causing the brightness of the explosion-proof floodlight to become lower and lower, so the dust removal mechanism is installed on one side of the explosion-proof floodlight, and under the work of the dust removal motor, the dust removal shell continuously sprays air, thereby forming an air wall on the surface of the lampshade to blow off the dust on the surface of the lampshade and prevent dust from falling on the surface of the lampshade.

[0018] It should be noted that different use environments correspond to different use methods, for example, the explosion-proof floodlight under the mine needs to be turned on for a long time, so the power of the corresponding dust removal motor should be small to ensure that the dust removal mechanism can spray uniform air wall; for the floodlight used in the flour mill, it may need to be turned on and off periodically, so a dust removal motor with larger power can be selected for use, so that the dust adhering to the lampshade can be blown off at the beginning of use, thereby forming an air wall to prevent dust from falling on the lampshade.

[0019] The front part of the air uniformizing nozzle is a circular truncated cone structure, the middle part is a cylindrical structure, the tail part is a rectangular structure, and a flow straightening plate is fixedly installed in the rectangular structure; the flow straightening plate is used for discharging the gas more uniformly to form a gas wall to better clean the lampshade and prevent dust from falling on the lampshade to achieve a better lighting effect in cooperation with the adjusting mechanism; the front part of the air uniformizing nozzle is designed as a circular truncated cone structure to reduce the space for the gas flow and increase the flow rate of the gas; the middle part of the air uniformizing nozzle is designed as a cylindrical structure to make the gas flow more uniformly to the tail part of the air uniformizing nozzle; the tail part is designed as a rectangular structure to cooperate with the lampshade to form a gas wall to block the dust outside the gas wall; the filter screen is a flexible filter screen, and two return springs are fixedly installed on the filter screen and at the other end of the two return springs inside the dust removal shell; when the air is sucked, the flexible filter screen will stretch into the dust removal shell, at this time, the flexible filter screen will stretch the return spring, when the dust removal mechanism stops working, the return spring will quickly reset the flexible filter screen, and at the same time, the dust filtered by the filter screen can be shaken off, achieving the self-cleaning effect of the filter screen.

[0020] The heat dissipation mechanism comprises heat dissipation fins, a cold head, a circulating pump and heat dissipation pipes, the heat dissipation fins are fixedly installed at the tail part of the shell, the heat dissipation fins are arranged in a radial manner, a plurality of fins are derived from the X-shaped main framework of the heat dissipation fins, the middle end radiator uses a circular base to derive a plurality of independent fins in a radial manner, the heat dissipation fins are bifurcated at the top end part of the fins to greatly increase the area of the fins; and the heat dissipation fins are made of a solid pressure process, the cold head is fixedly installed in the heat dissipation fins, and the cold head is made of polyimide material; the circulating pump is fixedly installed in the cold head, and the circulating pump is used to drive the water cooling water to circulate after being electrified to dissipate heat for the floodlight; the heat dissipation pipes are fixedly installed at the output end and the input end of the circulating pump, and the heat dissipation pipes are used for water flow.

[0021] The heat dissipation pipes are arranged in an S-shaped structure array, and the cooling strips are arranged with the heat dissipation pipes on one side and in contact with the heat dissipation pipes; the heat dissipation pipes are designed as an S-shaped structure to increase the contact area of the heat dissipation pipes and the heat dissipation fins, and the heat dissipation pipes are arranged on one side of the cooling strips to reduce a small amount of heat generated when the light supplementing lamp is turned on.

[0022] Transparent convex points are arranged inside the lampshade in a random manner; the transparent convex points are arranged inside the lampshade to change the illumination direction of the light emitted by the floodlight through the refraction of the convex points, avoiding the glare effect caused by the light irradiating to one position; and the transparent convex points are arranged on the lampshade in a random manner to avoid the light emitted by the floodlight being regular, thereby realizing a diffuse reflection effect, so that the light irradiating to one point can be avoided to cause glare.

[0023] The beneficial effects of the present application are as follows:

[0024] 1. The present application sets an adjusting mechanism inside the lampshade, controls the movement of the adjusting mechanism through the temperature change inside the lampshade, and cooperates with the heat dissipation mechanism to better dissipate heat inside the lampshade and also to compensate for the light decay effect of the floodlight due to excessive temperature, so that the workers can always work under stable illumination, thereby avoiding the discomfort caused by sudden reduction of illumination and ensuring normal work efficiency.

[0025] 2. The present application sets a dust removal mechanism, which cooperates with the adjusting mechanism to effectively prevent dust from entering the inside of the lampshade, and also to remove dust attached to the lampshade and prevent dust from falling on the lampshade, thereby avoiding the accumulation of dust on the lampshade, which affects the light transmittance of the lampshade and reduces the brightness of the floodlight, thereby affecting normal production work.

DETAILED DESCRIPTION

[0038] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in combination with the drawings of the specification and specific embodiments.

[0039] As Figures 1 to 10 shown, an industrial self-adaptive explosion-proof floodlight comprises a shell 1, a lamp 2 and a lampshade 3, characterized in that: the shell 1 is fixedly installed on a lamp stand, the lamp 2 is fixedly installed inside the shell 1, and the lampshade 3 is fixedly installed on the shell 1; an adjusting mechanism 4 is slidably installed inside the shell 1, and the adjusting mechanism 4 is used for automatically supplementing light inside the floodlight according to the temperature rise of the lamp 2 to ensure that the brightness of the floodlight is always constant; a dust removing mechanism 5 is fixedly installed on the left side of the lampshade 3, and the dust removing mechanism 5 is used for cooperating with the adjusting mechanism 4 to automatically clean dust on the surface of the lampshade 3; a heat dissipation mechanism 6 is fixedly installed inside the shell 1, and the heat dissipation mechanism 6 is used for reducing the temperature of the surface of the floodlight and cooperating with the adjusting mechanism 4 to make the temperature inside the lampshade 3 tend to be stable.

[0040] When working, the staff turns on the explosion-proof floodlight, at this time the lamp 2 is lit and the light is emitted from the lampshade 3, at this time the temperature inside the lampshade 3 begins to rise slowly, because the temperature inside the lampshade 3 rises, at this time the adjusting mechanism 4 begins to move forward to adjust the brightness of the floodlight, at the same time the dust removing mechanism 5 on the left side of the lampshade 3 begins to operate to prevent dust from adhering to the surface of the lampshade 3 and affecting the illumination effect of the floodlight.

[0041] In the above manner, self-adaptive adjustment of the explosion-proof floodlight in different environments can be realized, the light inside the lampshade 3 is automatically corrected according to the temperature change inside the floodlight, and the dust removing mechanism 5 installed on the left side of the lampshade 3 not only prevents dust from entering the lampshade 3 to cause explosion, but also prevents dust from adhering to the lampshade 3 to affect the illumination of the floodlight.

[0042] As Figures 2 to 4 shown in the adjusting mechanism 4, the adjusting groove 41, cooling strip 42, adjusting rod 43, temperature sensor 44, adjusting slider 45, light transmission lens 46, light supplement lamp 47 and conductive sheet 48, the adjusting groove 41 is embedded in the shell 1 inside, adjusting groove 41 for adjusting slider 45 sliding; the cooling strip 42 is fixedly installed in the adjusting groove 41, cooling strip 42 for heat transfer to the lampshade 3 in the outside of the shell 1; the adjusting groove 41 one end fixedly installed with adjusting rod 43, the adjusting rod 43 is fixedly installed with adjusting slider 45; The temperature sensor 44 is fixedly installed in the shell 1, the temperature sensor 44 is used to detect the temperature inside the shell 1 and push the adjusting slider 45 forward to move in cooperation with the adjusting rod 43, and then increase the contact area of high temperature gas and cooling strip 42 to make the temperature in the shell 1 drop; The light transmission lens 46 is fixedly installed between the adjusting slider 45, the light transmission lens 46 is used to refract the light emitted by the lamp 2 to the lampshade 3; The light supplement lamp 47 is fixedly installed in the adjusting groove 41, the light supplement lamp 47 is used to supplement light in the lamp 2 when the brightness of the lamp 2 is reduced due to high temperature, so as to keep the light effect stable; The conductive sheet 48 is fixedly installed on the adjusting slider 45 and the adjusting groove 41, the conductive sheet 48 is used to contact with each other with the movement of the adjusting slider 45 and then turn on the light supplement lamp 47;

[0043] When working, the temperature sensor 44 detects that the temperature in the lampshade 3 gradually rises due to the long time use of the floodlight, at this time the adjusting rod 43 extends to push the adjusting slider 45 to move forward, the adjusting slider 45 moves forward to drive the light transmission lens 46 to move forward, at the same time, the cooling strip 42 in the adjusting groove 41 is more in contact with the overheated gas in the lampshade 3, so as to cooperate with the heat dissipation mechanism 6 to better dissipate heat of the floodlight; At the same time, the conductive sheet 48 on the adjusting slider 45 and the adjusting groove 41 will contact during the movement of the adjusting slider 45, at this time the light supplement lamp 47 is turned on to supplement light for the floodlight with reduced brightness due to high temperature, to ensure the stability of the floodlight working;

[0044] By installing the adjusting mechanism 4 in the shell 1, the brightness of the floodlight can be automatically corrected when the brightness of the floodlight is reduced due to high temperature in the lamp 2, so as to avoid the influence of dark light on actual production, and the adjusting mechanism 4 can also adjust the contact area with the cooling strip 42 during movement, so as to automatically adjust the stability of the internal environment of the floodlight;

[0045] The following is an example of a brightness of 15000 lm of the explosion-proof floodlight, and the brightness of the fill light is 2500 lm. When the explosion-proof floodlight is full load operation, the temperature in the explosion-proof floodlight is about 80℃, which is 60℃ different from the most suitable temperature of 20℃ of the explosion-proof floodlight. According to the light decay characteristic curve, the brightness will decrease by 0.5% when the temperature increases by 1℃. Therefore, when the explosion-proof floodlight is operated at 15000 lm for a long time, the brightness calculation formula is:

[0046] 15000×(1-60×0.5%)=10500 lm

[0047] According to the formula of brightness and distance, we can know that:

[0048]

[0049] Where φ is the actual brightness, φ1 is the rated brightness, and d1 is the eye observation distance. When the eye observation distance is 2 meters, the actual brightness is:

[0050]

[0051] Similarly, the rated brightness is

[0052]

[0053] According to the above content, the difference between the rated brightness and the actual brightness of the floodlight in full load operation is 3750-2625=1125 lm

[0054] Since the brightness of the fill light is 2500 lm, and the fill light is on the left and right, the total brightness of the explosion-proof floodlight is calculated as

[0055]

[0056] Where φ 总 is the total brightness, and φ2 is the brightness of the fill light

[0057] According to the above calculation, 3875>3750, so the adjusting mechanism 4 can well correct the light decay phenomenon caused by temperature in the floodlight, so that the use of the floodlight becomes more stable.

[0058] As shown in Figures 3 to 4 , the fill light 47 is inclined at an angle of 45° inside the shell 1, and a reflector 49 is fixedly installed inside the shell 1. The reflector 49 is used to receive the light emitted by the fill light 47 and reflect it onto the lampshade 3. The reflector 49 corresponds to the fill light 47 one by one, and the plane where the reflector 49 is located is parallel to the plane where the lamp head of the fill light 47 is located.

[0059] Since the light supplement lamp 47 is located on the inner side of the shell 1, if the light of the light supplement lamp 47 is not inclined, it will be directly irradiated on the other side of the shell 1, so it is necessary to incline the light supplement lamp 47 to irradiate on the lampshade 3. The angle between the light supplement lamp 47 and the inside of the shell 1 is set to 45°, so as to irradiate more light on the reflector 49. The reflector 49 is fixedly installed in the inside of the shell 1, which is used to change the direction of the light irradiated by the light supplement lamp 47, so as to make the light of the light supplement lamp 47 irradiate on the lampshade 3.

[0060] As shown in Figure 7 The dust removal mechanism 5 includes a dust removal shell 51, a dust removal motor 52, a uniform gas nozzle 53, a dust removal air suction pipe 54 and a filter screen 55. The dust removal shell 51 is fixedly installed on one side of the shell 1. The dust removal shell 51 is L-shaped and the dust removal motor 52 is fixedly installed in the inside of the dust removal shell 51. The dust removal motor 52 is used to provide power for the dust removal mechanism 5. The output end of the dust removal motor 52 is fixedly installed with the uniform gas nozzle 53. The uniform gas nozzle 53 is used to spray the gas flow uniformly. The input end of the dust removal motor 52 is fixedly installed with the dust removal air suction pipe 54. The dust removal motor 52 sucks the gas through the dust removal air suction pipe 54 and sprays the gas through the uniform gas nozzle 53, so as to realize the dust removal effect on the surface of the lampshade 3. The filter screen 55 is fixedly installed in the inside of the dust removal air suction pipe 54. The filter screen 55 is used to filter the dust outside the filter screen.

[0061] In work, the worker opens the dust removal motor 52. The dust removal motor 52 starts to suck the gas. The gas reaches the uniform gas nozzle 53 after being filtered by the filter screen 55. The gas flow is sprayed uniformly in front of the lampshade 3 by the uniformization of the uniform gas nozzle 53, so as to effectively prevent the dust from adhering to the lampshade 3, thereby affecting the lighting effect.

[0062] Since the explosion-proof floodlight often acts in the environment with more dust, such as underground mine and flour mill, the floating dust will adhere to the lampshade 3 in the process of long time use. After a long time, it will affect the light intensity of the explosion-proof floodlight, thereby affecting the normal work. The existing worker often uses a wet cloth to wipe the lampshade 3. However, since the hanging position of part of the explosion-proof floodlight is high, the explosion-proof floodlight needs to be taken down every time for wiping. At the same time, it also needs to be carefully wiped. Part of the dust or dust will be difficult to wipe due to long time adhesion, which wastes a lot of manpower and material resources. The dust removal mechanism 5 can effectively prevent the dust from adhering to the lampshade 3. The gas wall formed by the flowing gas can prevent the dust from adhering to the lampshade 3, and can also blow away the dust adhered to the lampshade 3, thereby avoiding the influence of the dust adhesion on the lighting effect of the explosion-proof floodlight.

[0063] As shown in Figure 7As shown, the air uniformizing nozzle 53 is fixedly installed with a flow straightener 56; the flow straightener 56 is used to discharge the gas more uniformly to form a gas wall to better clean the lampshade 3 and prevent dust from falling on the lampshade 3 to cooperate with the adjusting mechanism 4 to achieve a better lighting effect; the front part of the air uniformizing nozzle 53 is set as a circular truncated cone structure to reduce the space for the gas flow and increase the flow rate of the gas; the middle part of the air uniformizing nozzle 53 is set as a circular cylinder structure to make the gas flow more uniformly to the tail part of the air uniformizing nozzle 53; the tail part is set as a rectangular structure to cooperate with the lampshade 3 to form a gas wall to block the dust outside the gas wall.

[0064] When the air is sucked, the flexible filter screen 55 will stretch into the dust removal shell 51, at this time, the flexible filter screen 55 will pull the reset spring 57 to stretch out, when the dust removal mechanism 5 stops working, the reset spring 57 will pull the flexible filter screen 55 to reset quickly, and at the same time, the dust filtered by the filter screen 55 can be shaken off to achieve the self-cleaning effect of the filter screen 55.

[0065] As shown in the figure, Figures 5 to 6 As shown, the heat dissipation mechanism 6 includes heat dissipation fins 61, a cold head 62, a circulating pump 63 and heat dissipation pipes 64, the heat dissipation fins 61 are fixedly installed at the tail part of the shell 1, and the heat dissipation fins 61 are used to exchange the heat in the lampshade 3 with the outside; the heat dissipation fins 61 are arranged in a radiating manner, the cold head 62 is fixedly installed in the heat dissipation fins 61, and the cold head 62 is used to provide a heat exchange place for the circulating water; the cold head 62 is made of polyimide material; the circulating pump 63 is fixedly installed in the cold head 62, and the circulating pump 63 is used to provide power for the circulation of the condensed water; the heat dissipation pipes 64 are fixedly installed at the output end and the input end of the circulating pump 63, and the heat dissipation pipes 64 are used to contact the floodlight to exchange the heat in the floodlight to the condensed water.

[0066] When the floodlight is turned on, the circulating pump 63 is also turned on, the circulating pump 63 drives the condensed water in the heat dissipation mechanism 6 to circulate, the circulating condensed water brings the heat in the floodlight into the condensed water, at this time, the circulating pump 63 drives the heated condensed water to the cold head 62, the heat exchange is completed through the heat dissipation fins 61 in contact with the cold head 62, and then the heated condensed water flows to the cooling pipe to complete the next round of cooling work.

[0067] As shown in the figure, Figures 5 to 6 As shown, the heat dissipation pipes 64 are arranged in an S-shaped structure array, and the heat dissipation pipes 64 are arranged on one side of the cooling strip 42 and in contact with the cooling strip 42; the heat dissipation pipes 64 are set as an S-shaped structure to increase the contact area of the heat dissipation pipes 64 and the heat dissipation fins 61, and the heat dissipation pipes 64 are arranged on one side of the cooling strip 42 to reduce the small amount of heat generated when the light supplementing lamp 47 is turned on.

[0068] As Figure 10 The transparent convex 31 is arranged in the lampshade 3, and the transparent convex 31 is arranged irregularly on the lampshade 3; the transparent convex 31 is arranged in the lampshade 3 to change the irradiation direction of the light emitted by the floodlight through the refraction of the convex, so as to avoid the glare effect caused by the light irradiating to a position; at the same time, the transparent convex 31 is arranged irregularly on the lampshade 3 to avoid the regular light emitted by the floodlight, thereby realizing a diffuse reflection effect, so that the light irradiating to a point can be avoided to cause glare.

[0069] During work, the temperature sensor 44 detects that the temperature in the lampshade 3 gradually rises due to the long-time use of the floodlight, at this time, the adjusting rod 43 is extended to push the adjusting slider 45 to move forward, the adjusting slider 45 moves forward to drive the light-transmitting lens 46 to move forward, at the same time, the cooling strip 42 in the adjusting groove 41 is more in contact with the overheated gas in the lampshade 3, so that the heat dissipation mechanism 6 can better dissipate heat for the floodlight; at the same time, the conductive sheet 48 on the adjusting slider 45 and the adjusting groove 41 is contacted during the forward movement of the adjusting slider 45, at this time, the light supplementing lamp 47 is turned on to supplement light for the floodlight;

[0070] At the same time, the dust removal motor 52 starts to inhale, the gas passes through the filter screen 55 to reach the uniform gas nozzle 53, and the gas flow is uniformly sprayed in front of the lampshade 3 through the uniformization of the uniform gas nozzle 53 to form a gas wall; the circulating pump 63 is opened, and the circulating pump 63 drives the condensate water in the heat dissipation mechanism 6 to circulate, the circulating condensate water brings the heat in the floodlight into the condensate water, at this time, the circulating pump 63 drives the heated condensate water to the cold head 62, and the heat exchange is completed through the heat dissipation fins 61 in contact with the cold head 62, and then the next round of cooling work is completed in the flow direction of the cooling pipe.
