Problems solved by technology
However, the casing 11a often accumulates dust and affects heat dissipation, and the casing 11a needs to increase its thickness to spread the heat evenly, and it must be made of metal die-casting with good thermal conductivity, resulting in increased system cost and weight
[0005] 2. The secondary optical design of the LED light source device 12a is usually a single mask, which is less expandable
[0006] 3. If you want to change the shape of the housing 11a, the structure of the overall LED lamp 1a needs to be changed relatively, and the heat dissipation needs to be redesigned
[0007] 4. There is another LED lamp that uses heat pipes (not shown in the figure) to export the heat generated by light-emitting diodes. However, adding heat pipes will increase the system cost and make maintenance difficult. At the same time, the system volume and complexity will increase, making it difficult to assemble

Embodiment Construction
[0063] see Figure 2 to Figure 6 , the present invention provides a modular LED lighting device 1 , including: a casing 11 , a light source structure group 12 and a power supply 13 .
[0064] In this embodiment, the casing 11 is a hollow box, and the material is not limited to a good heat conductor, for example, it can be a plastic part. The housing 11 includes a cover 111 and a seat 112. The cover 111 is provided with a plurality of air outlets 1111, a plurality of recesses 1112 and a plurality of pivotal joints 1113. The air outlets 1111 are elongated and spaced from each other. It is located on the top of the cover 111 . These recesses 1112 are respectively located at the air outlet 1111 and the vertical height is lower than the cover body 111. The recesses 1112 are streamlined, and their two ends are respectively connected to the cover body 111 to prevent dust or rainwater from directly entering the housing 11. . The pivoting portions 1113 are extended and curled to for...

Description
technical field [0001] The invention relates to a modular LED lighting device and the LED lighting device, in particular to a modular LED lighting device and the LED lighting device with expandability, easy maintenance and flexible shape design. Background technique [0002] Due to the advantages of high brightness, power saving and long life, light emitting diodes (LEDs) are widely used in lighting of various lamps, such as LED lighting devices for road lighting. However, light-emitting diodes generate a lot of heat when they emit light, and have poor heat resistance. Usually, heat dissipation devices must be used to remove the generated heat, so that the light-emitting diodes can emit light at an appropriate temperature without being burned. Therefore, if the heat dissipation design is not good, the high temperature will cause the brightness of the light-emitting diode itself to decrease, the lifespan will be shortened, and the wavelength will drift. In addition, because ...
