Abstract
Description
Technical Field
[0001] The utility model relates to the technical field related to floodlights, and in particular to a linear floodlight. Background Art
[0002] A floodlight is a lamp that provides a higher illuminance on a designated illuminated surface than the surrounding environment. Also known as a spotlight, it can typically be aimed in any direction and is designed to be unaffected by weather conditions.
[0003] Currently, linear floodlights installed in grooves opened in the wall are generally low-power, with the light-transmitting side facing outward. Since they are installed inside the wall, if high-power lamp panels are used, a large amount of heat will accumulate inside the floodlight and cannot be dissipated, thereby reducing the service life of the floodlight. Therefore, how to design a high-power linear floodlight that is suitable for installation inside the wall and has good heat dissipation effect has become a technical problem that needs to be solved. Utility Model Content
[0004] In order to overcome the existing technical defects, the purpose of the present invention is to provide a linear floodlight to solve the above technical problems.
[0005] The technical solutions adopted by the present invention to solve the technical problems are as follows:
[0006] According to one aspect of the utility model, a linear floodlight is designed, comprising: a lamp housing, a heat sink, an LED light strip, a PC cover, a temperature sensor, a first cooling fan, a second cooling fan and a control circuit board, wherein the heat sink is connected to the lamp housing and divides the interior of the lamp housing into a heat dissipation cavity and a lighting cavity, a plurality of heat sinks on the top of the heat sink are located in the heat dissipation cavity, the LED light strip is connected to the bottom of the heat sink, the temperature sensor is mounted on the LED light strip or on the heat sink, the PC cover is connected to the bottom of the lamp housing, a plurality of air inlet holes are provided at the front end of the PC cover, and a plurality of air outlet holes are provided at the rear end, the first cooling fan is mounted at the front end of the interior of the lamp housing, and its exhaust end corresponds to the air inlet hole, for driving external air into the heat dissipation cavity through the air inlet hole, the second cooling fan is mounted at the rear end of the interior of the lamp housing, and its outlet end corresponds to the air outlet hole, for driving the air in the heat dissipation cavity to be discharged through the air outlet hole, the LED light strip, the temperature sensor, the first cooling fan and the second cooling fan are electrically connected to the control circuit board respectively.
[0007] By adopting the above technical solution, when the floodlight of the present application is embedded in the wall and installed and the lighting is turned on, the internal temperature can be detected by the temperature sensor. When the temperature is higher than the set temperature, the information is fed back to the control circuit board. The control circuit board controls the first cooling fan and the second cooling fan to start, driving the external wind into the heat dissipation cavity through the air inlet and discharged from the air outlet, thereby realizing the heat dissipation of the floodlight. The heat dissipation effect is good, which can increase the service life of the floodlight, and solves the technical problem that a large amount of heat will accumulate inside the existing high-power floodlight after it is turned on and cannot be dissipated quickly, resulting in a short service life of the floodlight.
[0008] In order to better solve the above technical defects, the present invention also has a better technical solution:
[0009] In some embodiments, a thermal grease layer is provided between the LED light bar and the heat sink, thereby improving the heat conduction and heat dissipation effects.
[0010] In some embodiments, the lamp housing includes a U-shaped housing and end caps fixedly connected to both ends of the U-shaped housing.
[0011] In some embodiments, slots are respectively provided on the left and right side walls inside the U-shaped shell, and the left and right ends of the heat sink are correspondingly plugged into the two slots.
[0012] In some embodiments, sealing sheets are provided at both ends of the heat sink, respectively, for sealing contact with the heat sink, the inner wall of the lamp housing, and the PC cover. This prevents airflow and dust from entering the lighting cavity and affecting the lighting effect. Since airflow contains dust, if dust enters the lighting cavity with the airflow, a layer of dust will form on the top of the PC cover over time, affecting the lighting effect.
[0013] In some embodiments, the PC cover is snap-fitted to the lamp housing. BRIEF DESCRIPTION OF THE DRAWINGS
