Description

  The present invention relates to an improved LED bulb structure, and more particularly to an improved LED bulb structure welded by ultrasonic technology.

Light emitting diodes (hereinafter simply referred to as LEDs) have advantages such as small volume, fast reaction speed, low electricity consumption, and long service life. It is widely applied to products and consumer products, and most particularly to light bulbs. Generally, a light bulb fixture is composed of a socket plate, at least one light bulb socket, and at least one light bulb. In order to save energy and reduce CO ₂ emissions in accordance with the current environmental policy, instead of a traditional filament light bulb. LED bulb is used. A conventional LED bulb is manufactured of a glass material, and a heat radiating member is further coupled to the base of the bulb base portion in order to derive heat from the internal LED. Conventional LED bulbs have the following drawbacks.
1. Since the light bulb is made of a glass material, it easily breaks and causes danger, and the overall weight increases.
2. Since the light bulb and the base cap are bonded with an adhesive, airtightness is low, and moisture and corrosive gases (eg, ammonia gas, hydrogen sulfide, etc.) are generated when used outdoors or in special work. There are problems such as accidental electric shock due to intrusion or internal circuits and elements being easily damaged or invalidated.
3. Since the directivity of the LED is high, it becomes difficult to apply in a wide illumination range.
