Description

Technical Field

[0001] This application relates to the field of LED lights, and more particularly to an LED light with high heat dissipation efficiency. Background Technology

[0002] LED energy-saving lamps are a new generation of lighting source following compact fluorescent lamps (i.e., ordinary energy-saving lamps). LED energy-saving lamps are environmentally friendly, mercury-free, recyclable, low power consumption, high luminous efficiency, long lifespan, instant on / off, resistant to frequent switching, low light decay, rich colors, dimmable, and offer a variety of color variations.

[0003] In the use of existing LED lights, since the light source itself does not emit infrared or ultraviolet rays, and if the light source itself overheats and does not have a radiation heat dissipation function, the heat of the LED light will accumulate too much after long-term use and cannot be dissipated in time. This will first cause light decay and a decrease in brightness, and secondly, the high temperature will also cause certain high-temperature failures to the internal components of the LED light. Utility Model Content

[0004] To address the problem of excessive heat accumulation in LED lights after prolonged use, which can lead to light decay and reduced brightness, and also cause high-temperature malfunctions to internal components of the LED light, this application provides an LED light with efficient heat dissipation.

[0005] The high-efficiency heat dissipation LED lamp provided in this application adopts the following technical solution:

[0006] The device includes a housing and a lamp body. A DC brushless cooling fan is installed on the inner side of the housing. An outer plate is installed on the lower part of the housing. An inner ring is installed on the inner side of the outer plate. Cooling fins are installed on the side of the inner ring. The cooling fins are obliquely arranged and located below the DC brushless cooling fan.

[0007] By adopting the above technical solution, the airflow at the heat dissipation fins can be accelerated through the upper DC brushless cooling fan, thereby achieving the effect of heat dissipation.

[0008] Preferably, there are multiple heat dissipation fins, which are evenly arranged in a circle, and the multiple circumferentially arranged heat dissipation fins form an oblique channel.

[0009] By adopting the above technical solution, the air passes through the oblique channel, which can increase the contact area between the heat dissipation fins and the air. The air carries away some of the heat, and the air is exhausted from the opening by the DC brushless cooling fan, which further improves the heat dissipation effect.

[0010] Preferably, the outer plate has ventilation slots, and the number of ventilation slots is several, which are evenly distributed around the circumference.

[0011] By adopting the above technical solution, when the DC brushless cooling fan is working, the external air passes through the ventilation slot, enters the ventilation channel, and comes into contact with the outer side of the cooling ring, carrying away some of the heat on the cooling ring.

[0012] Preferably, a connecting piece is installed on the inner side of the outer plate, and a heat dissipation ring is connected to the outer plate through the connecting piece. The heat dissipation fins are located inside the heat dissipation ring, and the outer side of the heat dissipation fins is in contact with the inner wall of the heat dissipation ring. The heat dissipation fins, the heat dissipation ring, and the inner ring cylinder are all made of thermally conductive materials.

[0013] By adopting the above technical solution, when the temperature of the heat dissipation fins increases, the heat will pass through the heat dissipation ring, and some of the heat will be dispersed onto the heat dissipation ring, increasing the contact area between the heat and the air and reducing the temperature of the heat dissipation fins.

[0014] Preferably, the number of connecting pieces is four, arranged in a circle, and the inner side of the outer plate and the heat dissipation ring forms a ventilation channel.

[0015] By adopting the above technical solution, external air passes through the ventilation slot, enters the ventilation channel, and comes into contact with the outer side of the heat dissipation ring, carrying away some of the heat from the heat dissipation ring.

[0016] Preferably, the height of the outer plate is the same as the height of the inner ring cylinder, and the inclined channel and the ventilation channel are respectively arranged in an inner and outer correspondence.

[0017] By adopting the above technical solution, the air can pass through the oblique channel, which can increase the contact area between the heat dissipation fins and the air. The air carries away some of the heat. The external air passes through the ventilation slot, enters the ventilation channel, and contacts the outer side of the heat dissipation ring, carrying away some of the heat on the heat dissipation ring.

[0018] Preferably, a protective cover is installed on the upper part of the housing, and the protective cover is provided with a plurality of openings.

[0019] By adopting the above technical solution, a heat dissipation channel is formed by the opening and the oblique channel, and the opening and the ventilation channel form a heat dissipation channel, thereby improving the overall heat dissipation performance.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. This application directs the heat generated by the lamp body to the heat dissipation fins through the inner ring cylinder. The heat dissipation fins can increase the contact area with the air and better dissipate heat. Then, the DC brushless cooling fan at the top can accelerate the airflow at the heat dissipation fins. At the same time, the air passes through the oblique channel, which can increase the contact area between the heat dissipation fins and the air. The air carries away some of the heat and is discharged from the opening by the DC brushless cooling fan.

[0022] 2. This application uses heat dissipation fins to conduct heat to the heat dissipation ring. When the DC brushless cooling fan is working, external air passes through the ventilation slot, enters the ventilation channel, and comes into contact with the outer side of the heat dissipation ring, carrying away some of the heat on the heat dissipation ring. Then, the DC brushless cooling fan exhausts this part of the air from the opening, further improving the heat dissipation effect. Attached Figure Description

[0028] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0029] This application discloses a high-efficiency heat dissipation LED lamp, including a housing 1 and a lamp body 3. A DC brushless cooling fan 4 is installed on the inner side of the housing 1. An outer plate 2 is installed on the lower part of the housing 1. An inner ring cylinder 5 is installed on the inner side of the outer plate 2. Heat dissipation fins 6 are installed on the side of the inner ring cylinder 5. The heat dissipation fins 6 are obliquely arranged and located below the DC brushless cooling fan 4. There are multiple heat dissipation fins 6, which are evenly arranged in a circle. The multiple circumferentially arranged heat dissipation fins 6 form an oblique channel 7. Through the heat dissipation fins 6, the contact area with the air can be increased, and heat dissipation can be better. Then, through the DC brushless cooling fan 4 above, the air flow at the heat dissipation fins 6 can be accelerated. At the same time, the air passing through the oblique channel 7 can increase the contact area between the heat dissipation fins 6 and the air. The air carries away some heat and is discharged from the opening through the DC brushless cooling fan 4, thereby improving the heat dissipation effect.

[0030] The outer plate 2 has ventilation slots 12, which are evenly distributed in a circle. A connecting piece 9 is installed on the inner side of the outer plate 2. The outer plate 2 is connected to a heat dissipation ring 10 through the connecting piece 9. The heat dissipation fins 6 are located inside the heat dissipation ring 10, and the outer side of the heat dissipation fins 6 is in contact with the inner wall of the heat dissipation ring 10. The heat dissipation fins 6, the heat dissipation ring 10, and the inner ring cylinder 5 are all made of thermally conductive material. There are four connecting pieces 9 arranged in a circle. The outer plate 2 and the inner side of the heat dissipation ring 10 form a ventilation channel 11. When the DC brushless cooling fan 4 is working, the external air passes through the ventilation slots 12 and enters the ventilation channel 11, contacts the outer side of the heat dissipation ring 10, and carries away some of the heat on the heat dissipation ring 10. Then, the DC brushless cooling fan 4 passes this part of the air out of the opening.

[0031] The height of the outer plate 2 is the same as the height of the inner ring cylinder 5. The inclined channel 7 and the ventilation channel 11 are respectively arranged in an inner and outer correspondence. A protective cover 8 is installed on the upper part of the casing 1. The protective cover 8 is provided with several openings. The hot air is discharged from the openings through the DC brushless cooling fan 4. The openings and the inclined channel 7 form a heat discharge channel, and the openings and the ventilation channel 11 form a heat discharge channel, which improves the overall heat dissipation performance.

[0032] The implementation principle of an efficient heat dissipation LED lamp according to this application embodiment is as follows: During actual installation, the lamp body 3 and the DC brushless cooling fan 4 are powered to make the DC brushless cooling fan 4 work. When the lamp body 3 generates high heat, the heat generated by the lamp body 3 is directed to the heat dissipation fins 6 through the inner ring cylinder 5. The heat dissipation fins 6 can increase the contact area with the air and better dissipate heat. Then, the DC brushless cooling fan 4 at the top can accelerate the air flow at the heat dissipation fins 6. At the same time, the air passes through the oblique channel 7, which can increase the contact area between the heat dissipation fins 6 and the air. The air carries away some heat and is discharged from the opening through the DC brushless cooling fan 4, further improving the heat dissipation effect.

[0033] When the temperature of the heat sink 6 increases, it will pass through the heat sink ring 10, and some of the heat will be distributed to the heat sink ring 10. When the DC brushless cooling fan 4 is working, the external air passes through the ventilation slot 12 and enters the ventilation channel 11, comes into contact with the outer side of the heat sink ring 10, and carries away some of the heat on the heat sink ring 10. Then, the DC brushless cooling fan 4 will exhaust this part of the air from the opening.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
