Abstract

The invention relates to an inflatable LED lamp bulb utilizing SMT technology.The inflatable LED lamp bulb utilizing SMT technology comprises a bulb housing, a bulb holder, a support and a lamp filament assembly. A cavity is formed in the interior of the bulb housing. The bulb holder is located outside the cavity and installed on the bulb housing.The support is arranged in the cavity and fixedly connected with the bulb housing.The lamp filament assembly comprises LEDS packaged by SMD or CSP. The LEDs are adhered on a circuit board by utilization of SMT technology.The circuit board is in the shape of a long strip. Two ends of the circuit board are fixed on the support.The multiple LEDs are arrayed on the circuit board in order. A single-packaged LED is packaged on a bendable circuit board. The structure is more reliable and yield rate is improved. The inflatable LED lamp bulb utilizing SMT technology has following beneficial effects: due to the fact that the circuit board is in the shape of a long strip and can be bent, bending shaping can be carried out according to needs; the bulb is not easy to damage during processing so that processing difficulty is reduced and qualification rate is improved; higher power is achieved; and the lamp filament assembly is not easy to damage and not easily subjected to light attenuation.

Description

technical field [0001] The invention relates to the technical field of lamps, in particular to an inflatable LED light bulb with SMT technology. Background technique [0002] General LED light bulbs need to be provided with metal heat sinks, and LEDs are arranged on the metal heat sinks to achieve efficient heat dissipation. However, such LED light bulbs are relatively bulky, and it is difficult to emit light at full light angles. In order to overcome the above problems, LED filaments can be used to replace the structure in which LEDs are arranged on metal heat sinks, so that LED bulbs are light and light, and can emit light at full light angles. [0003] However, ordinary LED filaments are easily damaged, and cannot achieve high power, such as 8W or more. If the power is high, the temperature of the LED filament will be relatively high, and light decay is likely to occur. Contents of the invention [0004] Based on this, it is necessary to provide an inflatable LED light...
