[0032] Please refer to Figures 1-11The utility model discloses an embodiment of a kind of LED energy-saving lamp tube, including LED lamp tube 1, the rear of LED lamp tube 1 is provided with heat dissipation mechanism 2, control mechanism 3 is provided between heat dissipation mechanism 2 and LED lamp tube 1, heat dissipation mechanism 2 includes lamp house 201, first air inlet bin 202, first heat dissipation fan 203 and blast duct 204, the left and right ends of LED lamp tube 1 are provided with lamp house 201, the rear end of lamp house 201 is fixedly installed with first air inlet bin 202, first air inlet bin 202 is installed with first heat dissipation fan 203 in its inside, the left end of first air inlet bin 202 is fixedly connected with blast duct 204, blast duct 204 is communicated with first air inlet bin 202, heat dissipation mechanism 2 further includes second air inlet bin 205 and second heat dissipation fan 206, blast duct 204 is attached on the outer wall of LED lamp tube 1, the middle part of blast duct 204 is fixedly installed with second air inlet bin 205, second air inlet bin 205 is installed with second heat dissipation fan 206 in its inside, the rear of LED lamp tube 1 is provided with lamp shade body 207, the left and right ends of lamp shade body 207 are fixedly installed with connecting seat 208, connecting seat 208 is installed with rotating stand 209 at the rear end, rotating stand 209 is fixedly installed with mounting plate 210 at the rear end;

[0033] Wherein, heat dissipation mechanism 2 adopts double fan and wind pipe structure, forms high-speed airflow channel on the outer wall of LED lamp tube 1, can quickly guide away the heat on LED lamp tube 1, realizes the effect of reducing the temperature of LED lamp tube 1 quickly, ensures that LED lamp tube 1 is in non-overheating condition, guarantees the service life of LED lamp tube 1;

[0034] Control mechanism 3 includes SMA spring body 303, push block 304 and micro switch 306, the right end of SMA spring body 303 is fixedly installed with push block 304, the right side of push block 304 is provided with micro switch 306, control mechanism 3 further includes spring bin 301, the upper end of blast duct 204 is fixedly installed with spring bin 301, SMA spring body 303 is installed in the inside of spring bin 301, the outer wall of spring bin 301 is provided with vent groove 302, the upper end of micro switch 306 is fixedly installed with mounting bracket 305, mounting bracket 305 is fixedly installed on the inner wall of lamp shade body 207;

[0035] Referring to Figures 1-11Initially, before activation, the LED energy-saving lamp as a whole needs to be installed in the designated area in advance through the mounting plate 210, and the LED lamp 1 needs to be connected to the power supply and connected to the control terminal in advance, and the first heat dissipation fan 203 and the second heat dissipation fan 206 are connected to the power supply and connected to the micro switch 306. When activated, first turn on the LED lamp 1. When the LED lamp 1 is working, a large amount of heat will be generated in the closed lamp, and due to the closed space, the heat cannot be effectively dissipated to the external environment, causing the internal temperature of the lamp to rise. The LED chip is very sensitive to temperature, and when the temperature rises, the efficiency and service life of the LED chip will be affected. When the ambient temperature rises to 55℃, the SMA spring body 303 made of memory alloy will expand and stretch. When the SMA spring body 303 stretches, it will push the push block 304 from left to right, so that the push block 304 pushes the micro switch 306, and after the micro switch 306 is opened, the first heat dissipation fan 203 and the second heat dissipation fan 206 inside the brake heat dissipation mechanism 2 are opened. The first heat dissipation fan 203 works, and the second heat dissipation fan 206 blows air into the air duct 204 from right to left. At the same time, the second heat dissipation fan 206 blows air in the middle of the air duct 204, so as to form a high-speed heat dissipation airflow from right to left in the air duct 204. This part of the airflow adheres to the outer wall of the LED lamp 1, which can quickly and effectively guide the heat on the outside of the LED lamp 1 away, thereby achieving the effect of high-speed heat dissipation. When the ambient temperature of the LED lamp 1 decreases and the temperature is lower than 55℃, the SMA spring body 303 will shrink. At this time, the SMA spring body 303 no longer contacts the micro switch 306, and the micro switch 306 is closed. The first heat dissipation fan 203 and the second heat dissipation fan 206 are also closed, so as to realize the effect of automatically starting and stopping the first heat dissipation fan 203 and the second heat dissipation fan 206. According to the actual temperature, the heat dissipation fan is accurately started. Without the need for long-term activation of the heat dissipation fan, the effect of saving electric energy can be achieved.

[0036] Among them, the control mechanism 3 uses SMA spring body 303 as a trigger, and the SMA spring body 303 uses nickel-titanium-based shape memory alloy. The austenite starting temperature (As) of the nickel-titanium-based shape memory alloy can be set to ≤55℃ through composition control, combined with solid solution aging heat treatment and pre-deformation programming. In simple terms, the SMA spring can be accurately triggered to stretch and deform at 55℃, meeting the temperature control driving requirement, and realizing the effect of energy-saving self-driven heat dissipation mechanism 2.

[0037] The working principle of the utility model is: the LED energy-saving lamp tube realizes high-efficiency temperature control and energy saving through the heat-sensitive self-driving heat dissipation system, in the initial state, when the LED lamp tube 1 is electrified and works, the heat generated by the LED chip gathers near the lamp cover body 207, when the internal temperature rises to 55 DEG C, the SMA spring body 303 made of nickel-titanium-based shape memory alloy triggers the extension deformation, pushes the push block 304 to press the micro switch 306, triggers the double-fan linkage mode of the heat dissipation mechanism 2: the first heat dissipation fan 203 transports high-speed airflow from right to left through the air duct 204, the second heat dissipation fan 206 synchronously pressurizes in the middle section, forms the directional air duct through the outer wall of the lamp tube, and the heat on the surface of the LED lamp tube 1 is quickly led out through the lamp house 201 and the connecting seat 208; when the temperature drops below 55 DEG C, the SMA spring body 303 resets, the push block 304 is separated from the micro switch 306, the double fans stop working, and the system enters the low-power standby state.

[0038] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
