Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lighting devices, in particular to a dimmable LED lamp. Background Art
[0002] At present, the main problem of LED filament lamps is heat dissipation. The shape of the LED filament itself causes heat dissipation difficulties, which not only accelerates the light attenuation of the LED filament lamp, but also affects the service life of the LED filament lamp.
[0003] The Chinese utility model patent application number 202122757168.5 discloses a dimmable LED lamp. Under the above technical scheme, the second end of the lamp body is first connected to the lamp holder so that the LED lamp is connected to the external circuit. At this time, the LED can be turned on or off by an external button. When the LED lamp is turned on, the temperature of the lamp body will increase with time. The heat emitted by the lamp body can be transferred to the thermistor, causing the thermistor to expand, thereby connecting the circuit between the thermistor and the heat dissipation component. At this time, the heat dissipation component can dissipate heat to the lamp body. When the LED lamp is turned off, The temperature of the lamp body will decrease with the increase of time, the heat transferred from the lamp body to the thermistor will gradually decrease, and the thermistor will gradually shrink, thereby disconnecting the line between the thermistor and the heat dissipation component. In general, the LED lamp is provided with a thermistor so that the heat dissipation component can be started or shut down according to the temperature of the lamp body. When the heat dissipation component is started, the lamp body needs to reach a certain temperature to avoid waste of electricity resources and efficiently dissipate the heat of the lamp body. When the LED lamp is turned off, the heat dissipation component will start for a period of time under the action of the thermistor to accelerate the cooling of the lamp body, thereby improving the use of the LED lamp.
[0004] However, in actual use, when the above technical solution is used to dissipate heat for the LED lamp, the fan can blow wind into the interior of the accommodating cavity, and then the heat dissipation of the heat pipe can be achieved. However, since the heat dissipation pipe is not in direct contact with the lamp tube, the heat emitted by the lamp tube is difficult to be well transferred to the interior of the accommodating cavity, and it is difficult to dissipate heat for the lamp tube, and the heat dissipation effect is poor.
[0005] For this purpose, a dimmable LED lamp is proposed. Utility Model Content

The Bluetooth control module 11 is used here to dim the LED lamp by Bluetooth control, which is more convenient to adjust. It is also a prior art, so it will not be described in detail here. When the LED lamp is in use, it emits light and also generates a lot of heat. The light source board 7 is directly in contact with the coolant tank 402, and the heat can be exchanged with the coolant in the coolant tank 402. Under the action of the cooling fan 401, the coolant in the coolant tank 402 can be cooled. The cooling fan 401 can simultaneously blow air to the first cooling fin 403 and the second cooling fin 406, and can indirectly or indirectly dissipate the heat from the heat conducting sheet 405, thereby improving the cooling efficiency thereof. During heat dissipation, the air guide groove 404 can guide the wind, and thus the cold wind can be blown onto the transparent lampshade 501, thereby further directly dissipating the heat and preventing the transparent lampshade 501 from overheating and bursting.
[0026] like Figure 1 As shown, a threaded groove 301 is provided on the lamp holder 3, and the circuit connection of the electronic segmenter 8, the programmable electronic chip 9, the DC driver 10, the Bluetooth control module 11, the cooling fan 401 and the temperature sensor 6 is the prior art, so no further details are given here.
