Description

Technical Field

[0001] The utility model relates to the technical field of bulb lamps, in particular to an aluminum base of a bulb lamp. Background Art

[0002] The bulb is a new type of LED light source, and its appearance and interface are similar to those of traditional incandescent lamps. Bulbs use high-power LEDs as their light source, and their outer shell is usually made of aluminum alloy, which has excellent heat dissipation and anti-aging properties, resulting in a relatively long service life. However, the mounting base of traditional bulbs is a one-piece structure without heat dissipation holes. For example, an LED bulb with announcement number CN205877789U includes a housing, an aluminum substrate, an integrated circuit board, an optical bulb, and a lamp holder. The housing is located at the upper end of the lamp holder and is connected to the lamp holder. The optical bulb is located at the upper end of the housing. The aluminum substrate and the integrated circuit board are located in the enclosed space formed by the optical bulb and the housing. A hollow area is provided in the center of the aluminum substrate. The integrated circuit board is located above the aluminum substrate and is connected to the aluminum substrate by patch welding. In this patent document, the housing for mounting the optical bulb is a one-piece structure, which mainly relies on the material properties of the housing itself to achieve heat dissipation, resulting in low heat dissipation efficiency. Long-term use will cause the LED light source to degrade in performance due to heat accumulation, accelerate light decay, and shorten the overall service life of the bulb.
