Title:
LAMP WITH HIGH HEAT DISSIPATION EFFICIENCY
Document Type and Number:
WIPO Patent Application WO/2020/252686
Kind Code:
A1
Abstract:
Provided is a lamp (1) with high heat dissipation efficiency, comprising a lamp tube (11), a lamp bar (12), a power module (13), a power socket (14) and two outer covers (15). Each of two ends of the lamp tube (11) is provided with an opening (111), the lamp bar (12) is located in the lamp tube (11), and the power module (13) is arranged on one side of the lamp bar (12) and is electrically connected to the lamp bar (12); the power module (13) contains a first electrical base plate (131), wherein the first electrical base plate (131) is made of metal; and the power socket (14) is arranged on the other side of the lamp bar (12) and is electrically connected to the lamp bar (12), the two outer covers (15) are separately located on outer sides of the openings (111), and the outer covers (15) are combined with the lamp tube (11) to cover the openings (111). A metal-made base plate is used, except for the heat dissipation effect of the base plate itself, electrical connection with other metal-made base plates may also be realized through an electrical connection member, which is more conducive to dissipating the heat emitted by a heated electronic component, and a good heat dissipation effect is realized.
