Lighting device

Abstract

The invention provides a lighting device. The lighting device comprises a first heat radiation body, a second heat radiation body, a light source module, a light-transmitting element, and a driving circuit module. The first heat radiation body is provided with an inner side periphery and an inner side bottom which are used for forming an accommodation space on the first heat radiation body. The second heat radiation body is provided with a top and a bottom relative to the top and a through hole extending from the top to the bottom is formed; and the top of the second heat radiation body is connected with the first heat radiation body. The light source module is arranged on the inner side bottom of the first heat radiation body. The light-transmitting element is arranged in the accommodation space of the first heat radiation body and covers the light source module. The driving circuit module is arranged in the through hole of the second heat radiation body and is electrically connected with the light source module and drives the light source module.

Description

technical field [0001] The present invention relates to a lighting device, in particular to a lighting device that takes into account heat dissipation effect, built-in locking structure, and compliance with electrical regulations. Background technique [0002] Lighting devices are indispensable and important items in modern life. Among them, the light bulb used in the lighting device plays a key role affecting the quality of the lighting device. Accordingly, various improved light bulbs have been developed to increase the efficiency of the lighting device. At present, due to the advantages of long service life, high luminous efficiency, power saving and instant switching, light emitting diodes (LEDs) gradually replace traditional light bulbs and become the future trend of light sources. [0003] When the LED is in use, its stability and service life are closely related to its heat dissipation capacity. In other words, the heat dissipation capacity is a very important factor...

Problems solved by technology

[0004] However, most of the heat dissipation structures commonly used in current lighting devices have complex parts designs. In addition to causing inconvenience in assembly, their appearance also gives people a sense of clutter.

What's more, the mechanical structure of many lighting devices often meets the needs of heat dissipation or styling, and cannot fully meet the requirements of electrical safety regulations, so they cannot be sold on the market
