Abstract
Description
technical field
[0001] The invention relates to a design structure of a light bulb using LED as a light source, and belongs to the technical field of LED semiconductor lighting. Background technique
[0002] Existing LED light bulbs mostly use single-ended LED light sources, and use one-way reflective devices for light distribution. All heat is only dissipated through single-ended heat sinks. The disadvantages are that the heat dissipation area is small, the power cannot be increased, and the total output of LED bulbs The luminous flux is low, and the light loss of one-way reflection light distribution is large, and the overall system efficiency is low.
[0003] There is also a kind of LED light bulb that integrates the LED light source on a stem and places it in a closed bulb, so the heat dissipation efficiency is extremely low. The LED power cannot be increased, and the overall light output of the LED is low, which makes it difficult to meet customer requirements. Conte...
