Abstract: A LED light bulb includes a bulb envelope, a stem, at least two conductors, at least one LED light emitting module, and fluid. The bulb envelope has an opening, and a material of the bulb envelope includes soda-lime glass. The stem is connected to the bulb envelope and seals the opening. Here, the stem has a supporting portion and a pipe, the supporting portion is located in the bulb envelope, and the pipe has an open end inside the bulb envelope and a sealed end outside the bulb envelope. The conductors are located through the stem. The LED light emitting module is assembled to the supporting portion and coupled to the conductors. The fluid fills the bulb envelope. The bulb envelope made of soda-lime glass enhances visual effects produced by the shape, color and light reflection of the LED light bulb.

Abstract: An LED lamp has an LED device and a lamp base. The LED device has multiple LED chips, multiple conductive substrates, a packaging layer and a protective cover. The multiple conductive substrates are arranged at intervals. Each of the LED chips is supported by and electrically connected between two adjacent conductive substrates. The packaging layer covers the LED chips and covers a part of each conductive substrate. The protective cover covers the LED chips and the conductive substrates to form an LED device in a specific shape. As the LED chips are close to the protective cover, thermal energy generated by the LED chips is rapidly dissipated into the air to improve the heat dissipation. The LED device achieves a continuous uniform lighting effect by a proper arrangement of the LED chips.
