US Patent 11293598 Dual-resistor shatter-resistant bulb

The present invention relates to the technical field of bulbs, and discloses a dual-resistor shatter-resistant bulb. The shatter-resistant bulb includes a lamp holder and a bulb shell, and further includes a core column, a fixing base and a light-emitting component. The dual-resistor shatter-resistant bulb has the following advantages. First, a hollow structure of the fixing base helps save costs. Second, the core column and the fixing base are formed by injection molding, which can reduce the assembly processes, and prevent the bulb from breaking due to the falling core column, thus improving the falling resistance and prolonging the service life.
