Description

Exhaust cooling LED lamps

The invention relates to a luminaire structure, in particular to an exhaust heat-dissipating LED luminaire provided with a fan.

With the rapid development of science and technology, people have higher requirements for the efficacy of various kinds of things. They are no longer required to be used as they used to be. With the humanized thinking mode, the technology of light-emitting diodes (LED) has been developed. The continuous improvement of production technology, environmental protection and energy conservation, etc. are the topics advocated by people today, so the light-emitting diodes are also widely used in various lighting applications, and the market share has gradually increased. The light-emitting diodes are used in, for example, LED lamps, LED street lamps, LED desk lamps, and various types of display lamps, all of which are made using LED systems.

The technology of lighting diodes has the advantages of environmental protection, high brightness, power saving, durability, etc., and the application of the lamps and lanterns is constantly being updated. The lamps made by LEDs are compared with the traditional lamps. The benefits are very different. Therefore, a variety of LED lamps have been produced, and LED lamps that can achieve high brightness have become an ideal invention pursued by people.

Since the high-power light-emitting diode generates a very high heat source when the light source is emitted, although the effect of high brightness can be achieved, if the light-emitting diode cannot effectively reduce the accumulation of heat generated by the light-emitting diode, the light-emitting diode is caused. The high temperature generated by the body will further affect the normal operation of the whole or some of its components due to the influence of high temperature. The brightness and life of the LED will be relatively reduced, and most of the LED lamps are now illuminated by multiple lights. The combination of diodes produces heat that is higher than that of general lamps. Therefore, the heat caused by the complex LEDs is an urgent problem to be solved.

At present, the lamps manufactured by the conventional light-emitting diodes on the market are arranged on a heat-dissipating body, and a heat-dissipating hole structure is arranged around the lamps to facilitate the discharge of hot air out of the lamp housing. The heat dissipation structure design of the lamp belongs to the design of the negative mode, and the heat dissipation efficiency of the lamp is not high and the heat dissipation is negative, and the heat absorbed by the heat sink body cannot be forcibly and efficiently dissipated, and the heat dissipation efficiency is poor. Designed to meet the needs of today's high-brightness, high-efficiency LED lamps, the technology also uses heat sinks to place heat sinks on the LED illuminators for faster cooling. The previous technique of setting only the heat dissipation holes is better, but it is also a negative method. As in the case of using the heat dissipation holes described above, it is impossible to achieve the above-mentioned high-brightness and high-efficiency LED lamp heat dissipation requirements. Further, there is a way of using a fan to dissipate heat in a convection manner, but most of the heat dissipation effect on the structure is poor, and only the fan is blown on the LED. On the optical components, but the use of the fan is not optimized. It can also be used with high-brightness and high-efficiency LED lamps. If LED lamps with higher strength are required, the above methods are prone to overheating and shorten the service life. Since the brightness is reduced, the above disadvantages are improved one by one, and it is possible to achieve an LED lamp having high brightness but not easily causing overheating.

Therefore, in view of the problems existing in the above-mentioned conventional technical contents, how to develop an innovative structure of an LED lamp which can achieve high brightness and is not easy to cause overheating, and such a structure can be further utilized more widely, and is actually a public It is hoped that the operators involved in this aspect should work together to develop safer and more practical to solve this problem.

After working hard on the above objectives, the inventors have further improved the structure of the conventional LED lamps, and designed a heat dissipation structure to match the LED lamps, which can avoid the conventional high temperature and high temperature, and the heat dissipation method cannot be obtained. In combination with the heat generated by the LED light-emitting element, the LED lamp is damaged. This design can not effectively achieve environmental protection, power saving, and durability, but causes more loss. Therefore, the present invention utilizes a fan to increase the design for the fan. The baffle and the shroud structure can be designed to optimize the design of the fan, and the heat generated by the light-emitting diode can be more widely dissipated, so that the lamp is not easily caused. The high temperature overheating and the like occur, and the advantages of high brightness, environmental protection, power saving, durability and the like which are pursued today can be achieved, so that the present invention can produce the disadvantages of overcoming the above-mentioned prior art.

The main purpose of the present invention is to provide an exhaust heat-dissipating LED lamp, which mainly comprises a fan, a shroud, a baffle and an LED light-emitting component, and adopts the structure of a fan, a shroud and a baffle. The LED light-emitting element can be provided with a good heat dissipation effect.

A secondary object of the present invention is to provide an exhaust heat-dissipating LED lamp, which mainly comprises a flow guide cover and a baffle plate, and the structure of the flow guide cover and the baffle plate is used to make the LED lamp have a drainage effect.

Another object of the present invention is to provide an exhaust heat-dissipating LED lamp, which mainly comprises a fan and a plurality of guiding channels arranged on a deflector, so that the fan guides the air introduced into the deflector and can follow the diversion flow. The trough flows to make internal convection smooth and better heat dissipation.

In order to achieve the above-mentioned main purpose, the present invention provides an exhaust heat-dissipating LED lamp, which mainly provides a fan, a shroud, a baffle and an LED light-emitting element, and the middle of the shroud Having a ㄧ opening, a fan is disposed in the opening, a baffle is disposed on the fan and the shroud, the baffle has a plurality of diversion holes, and an LED illuminating element is disposed on the baffle The fan introduces air into the baffle, and forms a thermal convection of the air through the diversion hole to dissipate the heat on the LED illuminating element, and the fan and the opening are the same size, and the shroud completely covers the baffle The air introduced into the fan can only be discharged by the diversion hole on the deflector. The fan, the shroud and the baffle are arranged flat above and below, so that the air has a compression effect, and the air generated by the introduction of air is more Strong.

Further, a plurality of flow guiding grooves are arranged on the deflector, and the air introduced by the fan can be discharged along the flow guiding hole of the guiding groove, so that the internal air can be discharged downstream, and the heat dissipation effect is better.
