Description
Technical Field
[0001] The invention belongs to the technical field of lamps, and in particular relates to an LED floodlight. Background Art
[0002] As an outdoor lighting equipment, floodlights are widely used in architectural lighting, landscape lighting and other fields. They usually use high-intensity light sources and have the characteristics of high brightness and long range. Their casing is sturdy and durable and can adapt to various harsh environments. Through advanced optical design, precise beam control can be achieved to meet the lighting needs of different scenes.
[0003] At present, LED floodlights are generally fixedly installed at a certain position, and are provided with an adjustable structure. After the floodlight is fixed, the angle of the floodlight is adjusted appropriately through the adjustment structure, and then the LED floodlight can be used for lighting work, such as an LED floodlight disclosed in patent announcement number CN103017030B; In order to achieve high focusing and high brightness performance, LED floodlights now need to use lenses to focus light within a certain range. This will cause the light intensity in the middle of the LED floodlight's luminous surface to be higher than that at the edge. Under the action of light heat, the center of its luminous surface will produce a convex thermal expansion force, causing the edge to bend slightly. When part of the light is emitted through this position, edge astigmatism will occur, causing the boundary of the illuminated area to become blurred, reducing the clarity and contrast of the overall lighting, and causing some light to be wasted. At the same time, in the summer when mosquitoes are prevalent, LED floodlights used outdoors will attract phototactic mosquitoes due to their high brightness, causing mosquitoes to gather on the floodlight's luminous surface, which can also easily affect the lighting effect.

[0025] A mounting hole 17 is provided at the bottom of the mounting groove 10, and an air pressure switch 18 is installed inside the mounting hole 17. The air pressure switch 18 is electrically connected to the control main board 3. After being acted upon by air pressure, the moving contact of the air pressure switch 18 will be pushed back and closed, and the air pressure switch 18 will output an electrical signal to the control main board 3.
[0026] The operating principle of the present invention is now described as follows: a mounting hole 17 is drilled at a preset mounting position, and then the angle between the spotlight housing 2 and the two side panels 143 is adjusted to a required angle (the side walls of the two side panels 143 are both equipped with locking members, which are used to lock and fix the spotlight housing 2 after the adjustment of the spotlight housing 2 is completed to ensure the stability of the spotlight housing 2), and then the mounting seat 141 is aligned with the preset mounting position, and the mounting seat 141 is installed at the preset position through the fastener 142 (the fastener 142 is a bolt, expansion screw or other component), and then the control main board 3 is connected to the external power supply line; The light source board 1 can be controlled to work by controlling the main board 3 (for example, the light source board 1 can be started by pressing a start button on the main board 3, or the light source board 1 can be started by controlling a timing module inside the main board 3). The light source board 1 emits light, and under the refraction of the spotlight housing 2, the light is emitted through the transparent board 5, so that the area can be illuminated; When the light emitted by the light source board 1 is irradiated to the edge of the transparent board 5, since this part of the transparent board 5 is blocked by the reflective shell 6, the light scattered at the edge of the transparent board 5 will irradiate the inside of the reflective shell 6. Under the effect of the reflective coating inside the reflective shell 6, the light will be refracted again until the light is irradiated to the transparent frame board 7 and the warm color film 8. Since the warm color film 8 absorbs and reflects light of other colors and only allows light of the same color as itself to pass through, the light passing through the warm color film 8 will be warm light (for example, warm yellow, warm orange, etc., and the warm color film 8 can be set according to the light that mosquitoes in different regions like), the warm light will irradiate to the surface of the fixing seat 9, and be scattered outwards through the scattering protrusion 11. Since the range of the light emitted by the light source board 1 is The warm light is larger, which will attract mosquitoes from far away to fly around the surface of the transparent plate 5. After the mosquitoes fly around the transparent plate 5, the wavelength range of the warm light is closer to some signal lights preferred by mosquitoes in the natural environment (warm light may be recognized by mosquitoes as a potential food source, a suitable habitat or a mating signal, etc., thereby inducing a stronger phototaxis reaction of mosquitoes), and the white light emitted by the light source plate 1 is a mixture of multiple different wavelengths of light, lacking a specific wavelength component that is particularly attractive to mosquitoes, so the effect of attracting mosquitoes is relatively weak. Therefore, mosquitoes flying to the transparent plate 5 will be more easily attracted by the warm light at the fixing seat 9, thereby attracting mosquitoes to fly away from the transparent plate 5, reducing the impact of mosquito flying on the lighting effect of the floodlight; When the control main board 3 starts the light source board 1, the micro air pump 122 will be started synchronously. The micro air pump 122 will transport air to the inside of the frame-shaped air cavity 123 through the air delivery pipe 124, and the air will be ejected through each jet hole 125, so as to assist the air flow around the spotlight housing 2. Under the action of the flowing air flow, the heat around the spotlight housing 2 can be quickly dissipated. In the summer and other seasons with high incidence of mosquitoes, the killing button on the control main board 3 is started. After the control main board 3 starts the light source board 1, the micro electromagnetic push rod 133 will be started every 8 minutes, and the micro electromagnetic push rod 133 will work regularly for 3 minutes. When the micro electromagnetic push rod 133 is working, it can push the sealing pressing frame 134 out of the frame-shaped storage groove 131 and abut against the side wall of the fixing seat 9. At this time, the mosquitoes attracted to the fixing seat 9 will be enclosed by the sealing pressing frame 134, and the micro air pump 122 will transport The airflow will enter the inside of the sealing pressing frame 134, thereby increasing the air pressure inside the sealing pressing frame 134. After the micro-electromagnetic push rod 133 works for 1 minute, the control mainboard 3 controls the micro-air pump 122 to stop working. Since the body structure of mosquitoes is relatively fragile, when the air pressure inside the sealing pressing frame 134 increases, the mosquitoes will be squeezed by the rapid increase in external pressure, thereby causing the mosquitoes to deform and rupture, damage their internal organs, and hinder the normal operation of their respiratory system. Within 3 minutes of the micro-electromagnetic push rod 133 working at regular intervals, the mosquitoes will basically die quickly. After the micro-electromagnetic push rod 133 works at regular intervals, the control mainboard 3 resumes the operation of the micro-air pump 122. Since the airflow ejected from the jet hole 125 will be blown to the inner wall of the reflective shell 6, the mosquitoes that may remain in the reflective shell 6 will be blown off by the airflow. Among them, each time the control main board 3 starts the light source board 1, it will start a self-test work. At this time, the control main board 3 will control the normally open solenoid valve 158 and the normally closed solenoid valve 157 to work regularly for 1 minute, and start the micro air pump 122. The air flow delivered by the micro air pump 122 will enter the cavity 152 through the air delivery pipe 124, the shunt pipe 155, the connecting hose 156 and the air inlet pipe 154. Due to the increase in the air pressure inside the cavity 152, under the action of the air pressure, the pressure sealing block 164 will be pushed open, thereby opening the ventilation ring 163, allowing the air flow to escape. Since the pressure sealing block 164 is pushed by the air pressure, the moving contact of the pressure switch 162 will be closed. At this time, the pressure switch 162 will output to the control main board 3. If the mounting base 141 is not stably installed, the air pressure inside the cavity 152 increases. Under the action of the increased air pressure, part of the air flow will be discharged through the air vent 153. At this time, due to the increase in the number of air outlet points in the cavity 152, the air pressure at the air pressure hole 159 decreases. At this time, the moving contact of the pressure switch 162 cannot be pushed closed, so the control main board 3 will not receive the closing electric signal of the pressure switch 162. If the control main board 3 does not receive the closing electric signal of the pressure switch 162 within 1 minute of controlling the normally open solenoid valve 158 and the normally closed solenoid valve 157 to work regularly, the control main board 3 will issue an alarm prompt through its own alarm module (such as a buzzer, or a remote alarm through a wireless communication module, etc.); After the normally open solenoid valve 158 and the normally closed solenoid valve 157 finish their scheduled operation, the control mainboard 3 will control the micro-electromagnetic push rod 133 to work for 2 minutes. At this time, the sealing pressing frame 134 will be pushed out and abut against the side wall of the fixing seat 9. At the same time, the airflow delivered by the micro-air pump 122 will enter the interior of the sealing pressing frame 134 through the air delivery pipe 124, so that the air pressure inside the sealing pressing frame 134 increases. After the micro-electromagnetic push rod 133 works for 1 minute and 30 seconds, the control mainboard 3 controls the micro-air pump 122 to stop working, and controls the normally open solenoid valve 158 to work for 30 seconds. Since the airflow delivered to the sealing pressing frame 134 by the micro-air pump 122 is large, the air pressure inside the sealing pressing frame 134 increases, so that the moving contact of the air pressure switch 18 will be closed. At this time, the air pressure switch 18 will transmit an electrical signal to the control mainboard 3. If the sealing failure occurs at the connection between the mounting frame plate 4 and the spotlight housing 2, the air pressure inside the sealing pressing frame 134 will increase. The high air pressure in the upper part will enter the spotlight housing 2 through the sealing failure position. At this time, the air pressure in the sealing pressure frame 134 is reduced. At this time, the air pressure in the sealing pressure frame 134 is insufficient, so that the moving contact of the air pressure switch 18 will not be closed, thereby disconnecting the electrical signal output by the air pressure switch 18 to the control main board 3. On the contrary, if there is no sealing failure at the connection between the mounting frame plate 4 and the spotlight housing 2, the air pressure inside the sealing pressure frame 134 is maintained, so the control main board 3 will continue to receive the closing signal of the air pressure switch 18. After the closing electrical signal of the air pressure switch 18 received by the control main board 3 is disconnected, the control main board 3 will alarm through its own alarm module (such as a buzzer, or remote alarm through a wireless communication module, etc., which is different from the alarm signal when the mounting base 141 is installed unstable, so that personnel can distinguish them easily). After receiving the alarm signal, the personnel should promptly inspect and maintain the connection between the mounting frame plate 4 and the spotlight housing 2.
