Full-circumferential light-emitting diode bulb

The present invention relates to a light-emitting diode bulb, and more particularly to a full-circumferential light-emitting diode bulb that can emit 360 degrees.

After the invention of the light-emitting diode in 1962, the light-emitting diode (LED) has high durability, small volume, considerable power saving, mass production, and non-glare, and in recent years, the production of light-emitting diodes The technology has been improved, and the luminous efficiency has been greatly increased.

However, the lamp cover 62 of the conventional LED body 60 is connected in a bonding manner, unlike the glass lamp cover of the conventional tungsten light bulb at a high temperature. The uncured glass cover is directly joined to the socket 52, so that the lamp cover 62 of the LED bulb 50 is less securely connected to the socket 52. Furthermore, the light-emitting diode 60 is only mounted on the upper surface of the substrate 58, and only has an illuminating light source above, and the lamp holder 52 also blocks the direct route of the light source, so that the light-emitting diode bulb 50 can only emit light at 180 degrees, so the illumination area is equivalent.
