LED lamp with air exchange and rapid heat dissipation

The present invention relates to the design of an LED lamp, and more particularly to an LED lamp with airflow exchange and rapid heat dissipation.

Referring to FIG. 1 , a conventional LED lamp 1 includes a housing 11 having an accommodating space 111 , a protective cover 10 disposed on an end edge of the housing 11 , and a light source disposed in the accommodating space 111 . The module 12 and the heat sink 13; the light source module 12 has an electrically connected substrate 121, an optical reflector 122 disposed on the substrate 121, and at least one LED disposed on the substrate 121 The heat sink 13 has a fin set 131 disposed outside the optical reflector 122, and a fan 132 disposed under the substrate 121. Therefore, when used, the LED lamp 123 utilizes the The substrate 121 is connected to the supplied electric power, and the light is radiated through the optical reflector 122 for illumination, and the generated thermal energy is released to the outside through the fan 132 and the fin set 131.

However, it is found that, after the actual use, as shown in FIG. 2, the waste heat generated by the LED lamp 1 after being illuminated may be generated by the wind generated by the fan 132, and the waste heat is outwardly transmitted through the fin group 131. Released; however, the heat dissipation effect depends on the heat dissipation material coefficient. Therefore, if the fin group 131 uses a better heat dissipation material, it helps to dissipate heat, and if the material is used poorly, it may not be effective due to waste heat. Released, the LED lamp 1 is likely to be overheated, causing damage to the LED lamp 1.

Furthermore, the installation site is also one of the reasons that affect heat dissipation, if The seat body 11 of the LED lamp 1 is installed between the layers of the plywood such as the ceiling, or the space where the track lamp or the like can be exposed, and the LED lamp 1 as a whole has a better heat dissipation effect; The seat body 11 is embedded in the closed space on the ground G. When the LED lamp 123 passes through the optical reflector 122 to generate a large amount of waste heat during the long-time light source illumination, the seat body 11 of the LED lamp 1 is not only It is completely covered by the sealed ground G material, and the sealed protective cover 10 of the LED lamp 1 is designed so that only a small accommodation space 111 is available between the fin set 131 and the base 11. The air circulates, so the waste heat gas (shown by the dotted arrow in Fig. 2) is discharged outward, but the external cold air cannot be allowed to enter, which causes the external heat dissipation effect of the waste heat gas to be limited, so that a large amount of waste heat gas remains in the accommodating space 111. It is easy to cause the LED lamp 1 to overheat, which is very likely to cause damage to the LED lamp 1 and needs to be improved.

Therefore, the purpose of the present invention is to provide an LED lamp with airflow exchange and rapid heat dissipation, in particular, a plurality of channels are arranged in the fin group, and a plurality of channels are connected to the accommodating space of the luminaire to form a gas circulation cyclic exchange. The effect is to greatly improve the heat dissipation effect of the LED lamp.

Therefore, the novel LED lamp with airflow exchange and rapid heat dissipation includes a seat body formed with a receiving space, a light source module provided with the receiving space, and a pair of heat dissipating devices disposed in the light source module; The plurality of fins of the heat dissipating device are divided into a plurality of channels and a heat dissipating region, and each of the channels is connected to each other, and the heat dissipating regions are also in a state of mutual communication, and the e.g. Fan of the device Further, at least one of the guide holes communicating with the fin is formed on the peripheral wall of each channel, so that each channel is connected to the accommodating space, so that the outside air can be used by using the channels Guided into the body of the body, and by the blowing of the fan and the derivation of the heat dissipating area, the outside air can be circulated and exchanged in the accommodating space, so that the LED lamp of the light source module is generated in the body.
