Description

field of invention

[0001] The invention belongs to the technical field of LEDs, and in particular relates to a bulb lamp and a manufacturing method thereof. Background technique

[0002] Due to the difference in the light-emitting characteristics of LEDs and the structure of light-emitting diodes, the lighting range of LED lamps is limited, which greatly limits the practicability of LEDs. This defect is especially serious in some applications that require a large lighting range, such as bulb lamps or some applications that require lamps to have a consistent light effect in the 4Ο€ direction. Some manufacturers have innovated on this, by placing light-emitting diodes in the reflector to create an effect similar to a point light source, but limited to the surface light source characteristics of LEDs, this improvement still has uneven luminescence and cannot substantially improve As well as the issue of quantitative control of the light range, it can only provide spiritual comf...
