Description

Technical Field

[0001] The invention belongs to the technical field of electric light sources, and in particular relates to a split straight tube LED lamp. Background Art

[0002] The split straight tube LED lamp is a unique lighting device. The so-called "split" means that the lamp body and the LED lamp tube are split designs, which can be flexibly disassembled and combined, thereby facilitating the maintenance of the straight tube LED lamp and reducing the maintenance cost of the LED lamp. For example, the patent authorization announcement number is CN204084232U, which discloses a split straight tube LED lamp. Therefore, the split straight tube LED lamp is widely used in many fields such as commerce, industry, schools and offices, providing high-quality lighting for various spaces.

[0003] At present, during the use of split straight tube LED lamps, the light distribution conforms to the characteristics of Gaussian distribution, that is, the light distribution below the lamp shell is more and the brightness is higher, and the light distribution outside the irradiation range of the lamp shell is less and the brightness is lower. This is because the light of the split straight tube LED lamp reflects the light from the top of the straight tube LED lamp tube to the bottom of the lamp shell, which easily causes the light intensity below the lamp shell to be too strong. At the same time, the light brightness on both sides of the irradiation range of the lamp shell is weakened and cannot be used effectively, which leads to lighting defects of the split straight tube LED lamp, that is, the split in a space The arrangement density of straight tube LED lamps is relatively high, which increases the lighting cost of the space. In addition, the existing split straight tube LED lamps have poor moisture resistance. For example, in the "return of south wind" environment, the indoor space is too moist, and the moisture is easily condensed into water droplets on the indoor ceiling. The water droplets will then drip into the split straight tube LED lamp, thereby damaging the internal electronic devices and metal conductive parts of the split straight tube LED lamp, which not only affects the reliability of the split straight tube LED lamp, but also affects the service life of the split straight tube LED lamp.

[0014] Compared with the existing technology, the advantages of a split straight tube LED lamp are:

[0015] 1. By setting the illumination range expansion mechanism and the trapezoidal reflector, when the split straight tube LED lamp is installed, the straight tube LED lamp tube 2 is first lit. At this time, the light of the straight tube LED lamp tube 2 located at the bottom of the trapezoidal reflector 12 is constrained by the trapezoidal reflector 12 to irradiate downward, so that the space in the lighting area of ​​the trapezoidal reflector 12 can be effectively illuminated, ensuring that the light brightness can meet the use requirements. At the same time, the light located at the top of the trapezoidal reflector 12 is transported to the W-shaped light guide plate 11 through the light guide strip 15, and finally the light is transported to the inside of the hollow cover 14 along the two ends of the W-shaped light guide plate 11.

[0016] 2. Through the control mechanism microcontroller, air intake assembly, humidity sensor assembly and dehumidification mechanism, when the split straight tube LED lamp encounters humid weather such as "return of south wind" during use, the humidity sensor assembly 93 located on the top of the cover plate 13 detects that the humidity in the air exceeds the preset warning humidity threshold, and the humidity sensor assembly 93 sends an electrical signal to the microcontroller 91, and the microcontroller 91 controls the dehumidification mechanism 7 to work according to the electrical signal, and the dehumidification mechanism 7 sprays air to the split straight tube LED lamp through the second exhaust check valve 75. At the ceiling of the tubular LED lamp, high-speed air flow can speed up the air flow around the lamp. The air flow components can assist the lamp in dissipating heat, and can also prevent moisture in the air from condensing into water droplets in the room near the lamp, thereby preventing the water droplets from dripping into the lamp, and at the same time preventing the electronic devices and metal conductive parts in the lamp from being damaged by water droplets. This mechanism makes the split straight tube LED lamp moisture-proof, and effectively improves the reliability of the split straight tube LED lamp, as well as the service life of the split straight tube LED lamp.

[0017] 3. Through the temperature sensor component, air intake component, microcontroller, micro air pump and first exhaust one-way valve, when the lamp is in continuous use and the air humidity near the lamp does not exceed the warning threshold of the humidity sensor component 93, and the temperature sensor component 92 detects that the LED driver component 1 located inside the outer frame 3 generates too much heat to form a high temperature environment, the temperature sensor component 92 detects that the temperature exceeds the preset temperature threshold of the temperature sensor component 92, and sends an electrical signal to the microcontroller 91. The microcontroller 91 controls the dehumidification mechanism to transport air to the inside of the outer frame according to the electrical signal. The air can accelerate the heat dissipation at the LED driver component 1. After the heat dissipation, the air carries the heat and is discharged through the first exhaust one-way valve 74. The LED driver component 1 can be prevented from being damaged by high temperature, and the air intake component 6 can also dissipate the heat of the straight tube LED lamp 2 during the air suction process, and further dissipate the heat of the LED light source in the straight tube LED lamp 2, to prevent heat from accumulating at the LED light source to form a high-temperature environment, thereby ensuring the stability of the LED light source for long-term operation, avoiding the light decay of the straight tube LED lamp 2, and improving the stability of the light brightness diffused by the illumination range expansion mechanism 8. This mechanism enables the split straight tube LED lamp to have the function of preventing high-temperature damage, and effectively improves the reliability of the split straight tube LED lamp, and increases the service life of the split straight tube LED lamp.

[0031] The operating principle of the present invention is described as follows: after the split straight tube LED lamp is installed, the straight tube LED lamp tube 2 installed on the lamp tube conductive seat 4 is first lit by the LED driver component 1. At this time, the light of the straight tube LED lamp tube 2 located at the bottom of the trapezoidal reflector 12 is constrained by the trapezoidal reflector 12 to irradiate downward, so that the space in the lighting area of ​​the trapezoidal reflector 12 can be effectively illuminated, ensuring that the light brightness can meet the use requirements. At the same time, the light located at the top of the trapezoidal reflector 12 is transported to the W-shaped light guide plate 11 through the light introduction strip 15, and finally the light is transported along the two ends of the W-shaped light guide plate 11 to the inside of the hollow cover 14, and finally discharged through the light discharge transparent plate 83. Then the installer debugs the two illumination range expansion mechanisms 8 respectively through the two control switches 89. The micro-electric push rod 86 is started by controlling the switch 89, and the micro-electric push rod 86 controls the L-shaped plate 87 to slide, and the L-shaped plate 87 drives the rack 88 to move. The rack 88 rotates through the half gear, and the half gear drives the connecting sleeve 82 to rotate on the guide rod 81. At the same time, the connecting sleeve 82 drives the light discharge transparent plate 83 to deflect the angle, so that the light irradiated by the light discharge transparent plate 83 is seamlessly connected with the light constrained by the trapezoidal reflector 12, thereby expanding the effective lighting range of the split straight tube LED lamp, and avoiding the situation where the light intensity is too strong below the split straight tube LED lamp under the constraint of the trapezoidal reflector 12, further improving the uniformity of the light distribution of the lamp, and can reduce the density of the split straight tube LED lamp in the space to be lit, thereby reducing the lighting cost.

[0032] When the split straight tube LED lamp encounters humid weather such as "return of south wind" during use, the humidity sensor component 93 located on the top of the cover plate 13 detects that the humidity in the air exceeds the preset warning humidity threshold, and the humidity sensor component 93 sends an electrical signal to the microcontroller 91. The microcontroller 91 controls the three-way reversing solenoid valve 72 to be energized according to the electrical signal. The three-way reversing solenoid valve 72 can change the conduction direction after being energized, and the micro air pump 71 can suck air through the air intake component 6 after being energized. When the space passes through the air intake component 6, the dust in the air is intercepted by the filter mesh strips 62, and the moisture content in the air is reduced when passing through the dehumidification air intake check valve 61. This is because the dehumidification air intake check valve 61 A molecular sieve structure is provided inside, which can reduce the humidity of the inhaled air. Then the micro air pump 71 transports the sucked air to the bottom of the cover plate 13 and discharges it through multiple second exhaust one-way valves 75. The air discharged by the second exhaust one-way valve 75 is sprayed to the ceiling of the room where the split straight tube LED lamp is installed. The high-speed flowing air can accelerate the air flow around the lamp. This air flow can not only assist the heat dissipation of the lamp, but also prevent the moisture in the air from condensing into water droplets in the room at the lamp, thereby preventing the water droplets from dripping into the lamp and preventing the electronic devices and metal conductive parts in the lamp from being damaged by water droplets. In addition, when the lamp is in continuous use and the air humidity around the lamp does not exceed the humidity When the temperature sensing component 93 reaches the warning threshold of the temperature sensing component 93, and the temperature sensing component 92 detects that the LED driver component 1 located inside the outer frame 3 generates too much heat to form a high temperature environment, the temperature sensing component 92 detects that the temperature exceeds the preset temperature threshold of the temperature sensing component 92, and sends an electrical signal to the microcontroller 91. The microcontroller 91 controls the micro air pump 71 to work according to the electrical signal. The micro air pump 71 draws air through the air intake component 6, and then the micro air pump 71 delivers the air to the branch pipe 73 through the unpowered three-way reversing solenoid valve 72. Finally, the air enters the inner part of the outer frame 3 to accelerate the heat dissipation at the LED driver component 1. After the heat dissipation, the air carries the heat and is discharged through the first exhaust check valve 74 to avoid In the event that the LED driver component 1 is damaged by high temperature, the air intake component 6 draws air to dissipate the heat of the straight tube LED lamp 2, and further dissipate the heat of the LED light source in the straight tube LED lamp 2, to avoid heat accumulation at the LED light source to form a high-temperature environment, thereby ensuring the stability of the LED light source for long-term operation, avoiding the light decay of the straight tube LED lamp 2, and improving the brightness stability of the light diffused by the illumination range expansion mechanism 8. This mechanism enables the split straight tube LED lamp to have moisture-proof and high-temperature damage-resistant functions, and effectively improves the reliability of the split straight tube LED lamp, as well as the service life of the split straight tube LED lamp.
