Problems solved by technology
However, although this structure can help heat dissipation and heat insulation, due to the insufficient surface area of the lamp body, its heat dissipation efficiency is extremely limited. Because of this, this structure cannot be applied to larger power LED lamps.
In addition, due to the need to consume a relatively large accommodating space, it also causes the disadvantage that the volume of the light-emitting diode lamp is too large.
Furthermore, when the light-emitting diodes work to generate a large amount of heat, the power converter is arranged in the accommodation space of the lamp body for heat conduction and dissipation of the heat generated by the light-emitting diodes. When the lamp body lacks sufficient effective heat dissipation capacity, the electronic circuit components on the power converter are often overheated and damaged, resulting in a shortened overall product life

The intelligent function module comprises an information receiving unit, an information sending unit and a processing unit, the information receiving unit is used for being in wired connection or wireless connection with the outside and receiving information, the information sending unit is used for sending out sounds or projecting an image, and the processing unit is used for converting information received by the information receiving unit and providing the information for the information sending unit.
Description
technical field [0001] The invention relates to a light-emitting diode bulb, in particular to a light-emitting diode bulb capable of projecting images and / or emitting sound. Background technique [0002] A light emitting diode (Light Emitting Diode, LED) is a common electronic component nowadays, therefore, the light emitting diode is widely used in various electronic products. The light-emitting diode has many advantages, such as small size, fast response, long life, low power consumption and low calorific value, etc. Therefore, in recent years, light-emitting diode lamps have gradually been able to replace traditional incandescent bulbs and fluorescent lamps. There are also various LED lights. [0003] At present, the light-emitting diode light bulbs in the market generally have the function of radiator and accommodating the power converter at the same time, which is used to dissipate and dissipate the heat generated when the light-emitting diode works and the power conve...
