Problems solved by technology

Due to factors such as the size and shape of the bulb, the existing LED bulbs cannot provide a larger heat dissipation area, which also results in the inability of the existing LED bulbs to install more LEDs to meet the requirements of multi-faceted lighting.
[0004] In order to provide good heat dissipation for existing LED light bulbs, all or part of the lamp housing is generally made of metal such as aluminum, and the li

Example Embodiment

[0028] Example one:

[0029] Such as Figure 1 ~ Figure 4 As shown, the LED bulb of this embodiment includes a lamp cap 1, an insulating and light-transmitting housing with an inner cavity 2, a front end cover 3, a rear end cover 4, six light source power boards 5 integrated with LED chips, a cooling fan 6, four The insulating light-transmitting housing 2 is a profile, the insulating light-transmitting housing 2, the front end cover 3, and the rear end cover 4 are all made of plastic, and the insulating light-transmitting housing 2 The inner wall is provided with six sets of light source power board slots 21 extending in the axial direction, the light source power board 5 is inserted into the light source power board slot 21, and the heat dissipation fan 6 is fixed to the insulating light-transmitting shell In the inner cavity of the body 2, the front end cover 3 and the rear end cover 4 are each provided with a plurality of vent holes 90, and the connecting block 7 includes a c...

Example Embodiment

[0030] Embodiment two:

[0031] Such as Figure 5 , Figure 8 As shown, the difference between this embodiment and the first embodiment is: in this embodiment, the cross section of the connecting portion 70 and the connecting slot 22 is circular; the light source power supply board 5 is "I" That is, the two ends of the light source power board 5 are wider and the middle part is narrower. The two sides of the middle part form a channel for air flow between the front and back sides, so that not only the heat of the back side of the light source power board 5 can be It is taken away by the heat dissipation fan 6, and the heat on the front of the light source power supply board 5 can also be taken away by the heat dissipation fan 6 through the passage, so the heat dissipation effect is better.

[0032] The remaining features of this embodiment are the same as the first embodiment.

Example Embodiment

[0033] Embodiment three:

[0034] Such as Image 6 , Picture 9 As shown, the difference between this embodiment and the first embodiment is: in this embodiment, the cross section of the connecting portion 70 and the connecting slot 22 is rectangular; the light source power board 5 is provided on both sides There is a row of long holes 51, which are channels for air flow between the front and back.

[0035] The remaining features of this embodiment are the same as the first embodiment.

Description

technical field [0001] The invention relates to a multi-faceted high-power LED light bulb. Background technique [0002] Traditional light bulbs are generally incandescent light bulbs, which have low illuminance, dim light, and are not energy-saving; after incandescent light bulbs, fluorescent light bulbs (also known as energy-saving lamps) appeared. Powder, so not environmentally friendly. At present, there are more energy-saving and environmentally friendly LED light sources, and LED light bulbs are produced thereupon. LED has many advantages such as high luminous efficiency, energy saving and long life, and its application is becoming more and more extensive, representing the development direction of future lighting sources. Due to the inherent structure of the LED itself, the luminous angle of the LED light source is limited to a certain extent. For the sake of illumination, LED bulbs cannot emit light in all directions of the lamp body like traditional incandescent la...
