Description

Technical Field

[0001] The invention relates to the technical field of heat dissipation of LED lamps, and in particular to an LED lamp with high-efficiency heat dissipation. Background Art

[0002] Compared with traditional incandescent lamps, LED lamps have obvious advantages such as high efficiency and energy saving, so it has become a trend to replace traditional lamps with LED lamps. However, compared with incandescent lamps, LED lamps also have chips, drive circuits and other components, which require more space; in addition, the circuits and lights in the LED lamps will generate heat. If the heat is not dissipated in time, the temperature inside the lamp body will become higher and higher, which will accelerate the aging of the LED and even cause the LED lamp to burn out.

[0003] Patent number CN 103486468 A in the prior art discloses an LED lamp with high efficiency in heat dissipation, comprising: a lamp holder, a lampshade, a heat dissipation core column, a driving circuit and a plurality of LED lamp beads; the lamp holder and the lampshade are combined to form a closed space, and the heat dissipation core column placed in the closed space extends out from the lamp holder; the heat dissipation core column is provided with a driving circuit near the lamp holder, and a plurality of LED lamp beads are laid on the surface of the heat dissipation core column. The present invention can conduct heat to the lamp holder and the lampshade through the heat dissipation core column, and the heat is naturally dissipated by the lamp holder and the lampshade, and no additional heat dissipation equipment is required, the structure is simple and the cost can be reduced.

[0004] The prior art can achieve the heat dissipation effect for LED lamps, but the heat dissipation function cannot be adjusted. The LED lamp will gradually become hot when in use, and the time for heating will vary depending on the power of the LED lamp. The heat dissipation in the prior art can only be turned on or off, and the heat dissipation device cannot be adjusted according to the temperature inside the LED lamp, which affects the practicality of the heat dissipation effect. Moreover, when the temperature inside the LED lamp is too high, the LED lamp can only be turned off. Otherwise, the life of the LED lamp will be affected, and the LED lamp may even be damaged due to long-term high temperature. Summary of the invention

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] First, the present invention adds an LED lamp with high efficiency in heat dissipation, including a fixing mechanism, a lamp mechanism, a heat dissipation mechanism and a protective mechanism. The lamp mechanism and the heat dissipation mechanism are both arranged inside the fixing mechanism, the protective mechanism is arranged outside the fixing mechanism, the lamp mechanism is arranged below the heat dissipation mechanism, the working end of the heat dissipation mechanism corresponds to the lamp mechanism, and the protective mechanism covers the heat dissipation mechanism.

The LED lamp is arranged at the bottom of a circular supporting plate, and the lampshade is arranged around the LED lamp at the bottom of the circular supporting plate. The lampshade is provided with a plurality of heat dissipation holes. The temperature sensor is arranged in the heat dissipation mechanism, and the temperature sensor is connected to the LED lamp. The LED lamp is used to emit light, and the lampshade is used to protect the LED lamp. The heat dissipation holes provided on the lampshade can discharge the heat emitted by the LED lamp out of the lampshade. The temperature sensor is used to receive heat energy and send a heat signal to determine the power required to turn on the heat dissipation mechanism. The temperature sensor added to the lamp mechanism can accurately sense the heat emitted by the LED lamp and quickly issue a command to turn on the heat dissipation mechanism to reduce the temperature, which can solve the problem that the heat dissipation mechanism can only be turned on or off.

[0017] Thirdly, the present invention adds a protective mechanism, including two protective nets, both of which cover the fixed cooling fan and are arranged on the side walls outside the two sides of the lower bearing box, and the protective nets are used to protect the fixed cooling fan. The protective net added by the present invention can block some insects attracted by the bright light or prevent some foreign objects from entering the lower bearing box, and can prevent foreign objects from touching the fixed cooling fan, which can extend the service life of the fixed cooling fan.

[0018] Fourthly, the present invention adds a permanent heat dissipation component, including two fixed heat dissipation fans, which are respectively arranged in the first circular hole, the working ends of the two fixed heat dissipation fans correspond to the lampshade, and the two fixed heat dissipation fans follow the on or off of the LED lamp to determine the switch of the fixed heat dissipation fans, and the two fixed heat dissipation fans are used to dissipate the heat of the lower bearing box. The permanent heat dissipation component added by the present invention can be switched on or off according to the on or off of the LED lamp, and can be operated all the time, ensuring that the air in the lower bearing box is circulated with the external air.

[0019] Fifth, the present invention adds a refrigeration and heat dissipation component, including two relays and two cooling fins, each of which is provided with a relay, and the two cooling fins are respectively arranged on both sides of the lampshade, with the working ends of the cooling fins facing the interior of the lower bearing box, and the relays are used to drive the cooling fins to work, and the cooling fins are used to emit cold air, and the cooling fins can also cooperate with four regulating fans to work. When the four regulating fans and the cooling fins work at the same time, the regulating fans will blow the cold air emitted from the cooling fins toward the lamps, so that the heat emitted by the LED lamps can be quickly cooled. The refrigeration and heat dissipation mechanism added by the present invention can be used when the air in the lower bearing is already at a high temperature and cannot be quickly dissipated outside the lower bearing box, which can solve the problem that the temperature of the LED lamp cannot be quickly lowered by slow air circulation when it is turned on for a long time, and can ensure that the LED lamp will not be damaged by high temperature.
