Problems solved by technology

[0003] For this kind of hybrid heat sink designed as a lamp housing, for example, the first housing made of metal materials usually needs to be integrally made through a process similar to die-casting, so a high rate of defective products often occurs during the manufacturing process
And because the die-casting process has requirements for equipment and manufacturing time, its manufacturing cost cannot be ignored

Abstract

The invention relates to a lamp shell (100) of a lighting module. The lamp shell (100) comprises a first shell body (1) and a second shell body (2) which are made by different materials. The lamp shell (100) is characterized in that the second shell body (2) comprises a body part (21) and an assembling part (22) which are in heat contact, the second shell body (2) is integrally embedded into the first shell body (1) and in heat contact with the same, and the assembling part (22) and the body part (21) are mounted together. In addition, the invention further relates to a manufacturing method of the lamp shell and a lighting device with the lamp shell.

Description

technical field [0001] The invention relates to a lamp housing, a method for manufacturing the lamp housing and an illuminating device comprising the lamp housing. Background technique [0002] In the manufacturing process of modern electronic devices, especially LED lighting devices, more and more injection molding, especially inlay injection molding technology is used to manufacture lamp housings of lighting devices. Manufactured by this process, the lamp housing can not only achieve good heat exchange, but also be used to ensure that the lighting device has good insulation properties. In the prior art, a hybrid heat sink made of metal and plastic is usually used as the lamp housing of the lighting device. Such a lamp housing has a first metal housing and a second plastic housing that is coated on the outside of the first housing. Therefore, the heat inside the lighting device can be efficiently and quickly transferred to the second housing by virtue of the heat conducti...
