Embodiment Construction

[0015] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. In the interest of clarity and conciseness, not all features of an actual implementation are described in this specification. However, it should be understood that many implementation-specific decisions must be made in developing any such practical implementation in order to achieve the developer's specific goals, and that these decisions may vary from implementation to implementation . Moreover, it should also be understood that development work, while potentially complex and time-consuming, would at least be a routine undertaking for those skilled in the art having the benefit of this disclosure.

[0016] Here, it should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only the device structure closely related to the solution according to the present invention is shown in the drawings, and the relationshi...

Abstract

The invention discloses a heat dissipation device and a light-emitting diode (LED) lighting device. The heat dissipation device (4) is provided with a shaft portion (41) and a heat dissipation portion (42). The shaft portion (41) is tightly contacted with an additional device needing dissipating heat so that the additional device can rotate around the shaft portion (41) and transfer the heat of the additional device to the shaft portion (41). On the one hand, the heat dissipation portion (42) is in heat-conducting connection with the shaft portion (41); on the other hand, the heat dissipation portion (42) is in heat-conducting connection with an external radiator, thereby enabling the heat of the additional device to be transferred to the radiator from the shaft portion (41).

Description

technical field [0001] The invention relates to a heat dissipation device. In addition, the present invention also relates to a light-emitting diode (LED) lighting device, especially a high-power LED lighting device. Background technique [0002] In the design of many devices, good heat dissipation is an important aspect to be considered, because heat dissipation performance often affects the working efficiency and / or service life of the device. For example, in the case of LED lighting devices, especially high-power LED lighting devices, unsatisfactory heat dissipation can lead to a greatly shortened life of the LED lighting device. However, in practical applications, it is sometimes necessary to design the LED module in the lighting device to be rotatable in order to control the output direction of light. In this case, how to design the heat dissipation of the LED is a problem that needs to be solved. Contents of the invention [0003] The purpose of the present inventi...
