However, LED bulbs often cause damage to the circuit board or LED due to heat dissipation problems. Therefore, in order to make the LED bulb last for a long time and maintain a certain brightness, the LED bulb needs to be equipped with a heat sink to keep the LED light The generated heat energy is properly discharged to the outside. the

A general LED bulb lamp mainly includes an LED module and a heat dissipation structure.

In the above heat dissipation structure 10 of the LED bulb lamp, when applied to an LED module with high wattage, the temperature tends to concentrate on the outer edge 122 of the metal fin 12 , which cannot be touched directly by hand, which is dangerous to use. At the same time, the surface of the metal fin 12 is also prone to safety concerns or electromagnetic wave interference due to metal conduction. Although the original sharp outer edge 122 of the metal fin 12 has been anodized or sprayed with various paints, it still cannot avoid the safety problem of hand cuts. the

On the other hand, the LED module of the existing LED bulb lamp is limited by the design of the structure, and the luminous angle is limited. It can only have a semi-circular type, that is, the luminous angle is lower than 180 degrees, so that the entire LED bulb lamp has a narrow luminous angle. And the luminous intensity is not uniform. the

Bulb lamps have narrow light-emitting angles and lack of uneven luminous intensity caused by the straightness of the LED light source. the

One of the objectives of the present utility model is to provide a full-circumference light-emitting diode bulb lamp, in which the heat dissipation lamp shell, the light cover and the power base have a tight bonding degree, and the bonding degree is good. the

In order to achieve the above purpose, the full-circumference light-emitting diode bulb lamp according to an embodiment of the present invention includes: a power supply base; , each protruding surface extends upward along the outer surface from a bottom end of the heat sink lamp housing, and a groove is formed between adjacent protruding surfaces; a plurality of light source modules are respectively arranged on the protruding surfaces; and a plurality of The photomasks respectively correspond to the protruding surfaces and cover the light source modules. the
