Description

Technical Field

[0001] The utility model relates to the technical field of lamps, and in particular to a silent lamp with a heat dissipation air path. Background Art

[0002] Lamps are a general term for lighting tools, which are divided into chandeliers, table lamps, wall lamps, floor lamps, etc. It refers to an appliance that can transmit light, distribute and change the light distribution of a light source, including all parts required to fix and protect the light source except the light source, as well as the line accessories necessary for connecting to the power supply. The operating temperature of the lamp tube needs to be stable at around 400℃. Too high or too low will affect the life of the lamp tube. In order to cope with high temperatures, multiple low-speed and low-noise fans can be used to actively dissipate heat from the lamp tube.

[0003] Since the lighting application needs to achieve a relatively quiet effect, the low noise requirement limits the speed of the cooling fan when the lamp tube is air-cooled. The low wind speed causes the lamp outlet to discharge low-speed high-temperature airflow, and the airflow temperature reaches more than 120°C. The wind speed is slow, and the slow high-temperature airflow has the following hazards: (1) The slow high-temperature airflow will be sucked into the lamp body when the lamp body is in a vertical state, causing heat flow circulation, destroying the lamp body's heat dissipation system, and damaging the lamp. (2) When the lamp is placed flat or hung, the high-temperature airflow discharged by the lamp tube can blow to parts of the lamp at will, causing local overheating of the lamp, melting of plastic parts such as the outer shell, and other problems. (3) When the lamp is hung, if the high-temperature airflow enters the bottom box of the lamp, it will affect the operation of the electrical components of the bottom box and even cause damage to the lamp.

[0004] The lamps in the prior art are not convenient for better combining the mute function and the heat dissipation function, and the heat dissipation effect needs to be improved. There is a lack of a heat dissipation structure that is convenient for discharging high-temperature airflow. The durability and practicality of the lamps themselves need to be improved. At the same time, a utility model patent with announcement number CN215216153U discloses a lamp with a heat dissipation function, including a lamp housing, a heat dissipation cavity is arranged in the hollow inside of the lamp housing, a heat transfer structure, an air-cooled heat dissipation mechanism and a water-cooled heat dissipation mechanism are arranged inside the lamp housing, and the heat transfer structure includes: an insulating strip, a heat-conducting copper plate, a heat-conducting copper plate is fixedly installed at the bottom of the heat dissipation cavity, and an insulating strip is fixedly installed on the lower side of the heat-conducting copper plate inside the lamp housing. It is not convenient for the discharge of hot air and the mute effect is not good. Utility Model Content

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0031] This embodiment sets a heat dissipation component inside the lamp body, and can dissipate heat normally through the heat dissipation fan set by itself. The heat dissipation air path is formed by the air inlet and the air outlet, which is convenient for the air inlet and outlet and the normal operation of the heat dissipation fan. At the same time, the air inlet fan and the exhaust fan are respectively set at the air inlet and the air outlet, which can generate a low-speed cold airflow inside the lamp body and increase the wind speed of the heat dissipation inlet and outlet airflow of the lamp body. As the low-speed cold airflow flows downward, the slow upward high-temperature airflow for heat dissipation of the lamp tube will be quickly dispersed to avoid the slow high-temperature airflow from baking the surface of the lamp. It can also prevent the high-temperature airflow from concentrating on the air inlet of the lamp body and avoid the occurrence of heat flow circulation. In addition, the air inlet and exhaust airflow of the lamp body is a low-temperature airflow, which neutralizes the temperature of the high-temperature hot airflow for heat dissipation of the lamp tube and avoids local overheating of the lamp body caused by the high-temperature airflow. The specific implementation method is as follows:

[0032] like Figures 1 to 4 As shown, a silent lamp with a heat dissipation air path includes a lamp body 1, a heat dissipation component, a bottom box 4 and a fixing seat 7. The fixing seat 7 is installed on the top of the bottom box 4, and the lamp body 1 is rotatably installed on the fixing seat 7. The front and back of the lamp body 1 are respectively provided with air inlets 2 and air exhaust ports 3. Two corresponding air inlets 2 and two corresponding air exhaust ports 3 are connected up and down to form a heat dissipation air path from top to bottom. A heat dissipation component is installed in the heat dissipation air path. The heat dissipation component includes an air inlet fan 12, a heat dissipation fan 13 and an exhaust fan 14. The air inlet fans 12 are respectively installed on the inner sides of the two air inlets 2. The four side walls of the lamp body 1 near the two exhaust ports 3 are respectively installed with heat dissipation fans 13, and a plurality of exhaust fans 14 are evenly distributed between the four heat dissipation fans 13. A heat dissipation component is arranged inside the lamp body 1, which can dissipate heat normally through the heat dissipation fan 13 arranged by itself. A heat dissipation air path is formed by the air inlet 2 and the air outlet 3, which is convenient for air inlet and outlet and the normal operation of the heat dissipation fan 13. At the same time, an air inlet fan 12 and an exhaust fan 14 are respectively arranged at the air inlet 2 and the air outlet 3, which can generate a low-speed cold air flow inside the lamp body 1 and increase the wind speed of the inlet and outlet air flow of the lamp body 1 for heat dissipation. As the low-speed cold air flow flows downward, the high-temperature air flow generated by the slow upward heat dissipation of the lamp tube will be quickly dispersed to avoid the slow high-temperature air flow from baking the surface of the lamp, and can also prevent the high-temperature air flow from concentrating on flowing into the air inlet 2 of the lamp body 1 and avoid heat flow circulation. In addition, the air inlet and exhaust air flow of the lamp body 1 is a low-temperature airflow, which neutralizes the temperature of the high-temperature hot airflow for heat dissipation of the lamp tube and avoids local overheating of the lamp body caused by the high-temperature airflow.

[0033] Specifically, the outer surfaces of the two air inlets 2 and the two air outlets 3 are provided with ventilation grilles. The size of the air outlet 3 is larger than the size of the heat dissipation fan 13. Through the setting of the ventilation grilles, the fan surface can be protected. At the same time, the air outlet 3 is larger than the heat dissipation fan 13 so that heat dissipation and exhaust can be carried out simultaneously, thereby improving the exhaust efficiency.

[0034] Specifically, the outlet sides of the two air inlet fans 12 are arranged opposite to each other toward the interior of the lamp body 1. A light-emitting lamp is arranged at the center of the interior of the lamp body 1, and the blowing sides of the four heat dissipation fans 13 are all arranged toward the light-emitting lamp. The air inlet fans 12 generate a low-speed and low-temperature airflow which is gathered inside the lamp body 1 and then flows downward, and can meet the high-temperature airflow generated by the heat dissipation fan 13 for blowing air to the lamp tube, and prevent the high-temperature airflow from continuing to move upward. The low wind speed of the air inlet fans 12 is used to solve the heat dissipation problem of high-temperature lamps, which can effectively reduce the noise of the lamps and achieve the effect of silent lamps.

[0035] Specifically, a dustproof net is provided on the inner surface of each ventilation grid, and the dustproof net can prevent dust from entering the lamp body 1.

[0036] Specifically, the outer shell of the lamp body 1 is made of plastic, and a reinforcing plate 15 is installed on the outside of the lamp body 1. The reinforcing plate 15 arranged on the outside of the lamp body 1 can improve the strength of the lamp body 1 and make it less prone to damage.

[0037] Specifically, the inner and outer surfaces of the lamp body 1 are both provided with a high-temperature resistant coating 16. By providing the high-temperature resistant coating 16 on the inner and outer surfaces of the lamp body 1, the high-temperature resistance of the lamp body 1 can be enhanced, thereby increasing the service life of the lamp. At the same time, an insulating layer is also provided on the inner wall of the lamp body 1 to avoid electric shock due to leakage.

[0038] Specifically, the front and back sides of the bottom box 4 are respectively provided with a bottom box air inlet 5 and a bottom box air outlet 6, and the bottom box air inlet 5 and the bottom box air outlet 6 are correspondingly connected. By providing the bottom box air inlet 5 and the bottom box air outlet 6 on the bottom box 4, the heat dissipation effect of the bottom box 4 can be improved to prevent the hot air from affecting the use of the electronic components inside the bottom box 4.

[0039] Specifically, a switch plate 10 for controlling the lamp is arranged in the middle of the front of the bottom box 4, and a handle 11 is installed on the side wall of the bottom box 4. The switch plate 10 can be used to conveniently control the opening and closing of the lamp, and the handle 11 can be used to facilitate the lifting of the lamp.

[0040] Specifically, the fixing seat 7 is U-shaped, and the inner side of the fixing seat 7 is rotatably connected to the two sides of the lamp body 1. The lamp body 1 can be rotated by swinging it, thereby changing the lighting direction of the lamp.

[0041] Specifically, a transparent lampshade 9 is provided on the top of the lamp body 1, and support blocks 8 are provided at the four corners of the lower surface of the bottom box 4. The lampshade 9 facilitates the emission of light from the lamp and protects the light-emitting lamp tube of the lamp. The support blocks 8 facilitate the support of the lamp when it is placed horizontally, and the material of the support blocks 8 is rubber material.

[0042] Working principle: A heat dissipation component is arranged inside the lamp body, which can dissipate heat normally through the heat dissipation fan arranged by itself. A heat dissipation air path is formed by the air inlet and the air outlet, which is convenient for the air inlet and the air outlet as well as the normal operation of the heat dissipation fan. At the same time, an air inlet fan and an exhaust fan are arranged at the air inlet and the air outlet respectively, which can generate a low-speed cold airflow inside the lamp body and increase the wind speed of the heat dissipation inlet and outlet airflow of the lamp body. As the low-speed cold airflow flows downward, the slow upward high-temperature airflow for heat dissipation of the lamp tube will be quickly dispersed to avoid the slow high-temperature airflow from baking the surface of the lamp. It can also prevent the high-temperature airflow from concentrating on flowing into the air inlet of the lamp body and avoid the occurrence of heat flow circulation. In addition, the air inlet and exhaust airflow of the lamp body is a low-temperature airflow, which neutralizes the temperature of the high-temperature hot airflow for heat dissipation of the lamp tube and avoids local overheating of the lamp body caused by the high-temperature airflow. By providing a reinforcing plate on the outside of the lamp body, the strength of the lamp body can be improved to make it less susceptible to damage. By providing a high-temperature resistant coating on the inner and outer surfaces of the lamp body, the high-temperature resistance of the lamp body can be enhanced, thereby increasing the service life of the lamp. By providing air inlets and outlets on the bottom box, the heat dissipation effect of the bottom box can be improved to prevent hot air from affecting the use of its internal electronic components. By using the low wind speed of the air inlet fan to solve the heat dissipation problem of high-temperature lamps, the noise of the lamp can be effectively reduced to achieve a silent effect.
