Problems solved by technology

[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, which has extremely low heat dissipation efficiency.
The LED power cannot be increased, and the overall light output of the LED is low, which makes it difficult to meet customer requirements

Embodiment Construction

[0012] Such as figure 1 , figure 2 As shown, this embodiment uses 2 LED light sources, and 4, 6, and 8 LED light sources can also be used. The LED light bulb is composed of a lamp holder 1, a driver 2, a lower cooling block 3, a lower LED light source 4, a polyhedral light distribution optical device 5, a conductive support body 6, a transparent cover 7, an upper LED light source 8, and an upper cooling block 9. . The lower LED light source 4 is fixed on the lower cooling block 3, and the upper LED light source 8 is fixed at an appropriate position on the upper cooling block 9, which can quickly dissipate the heat generated by the upper and lower LED light sources, and at the same time support the middle polyhedral light distribution optical device 5. The conductive support body 6 is electrically connected to the lower LED light source 4 and the upper LED light source 8, so that the lower LED light source 4 and the upper LED light source 8 can be energized, and the multi-f...

Abstract

The invention relates to an LED bulb which belongs to the technical field of LED semiconductor illumination. The LED bulb comprises a lamp holder 1, a drive 2, a heat radiating block, an LED light source and a light transmission cover 7. The LED bulb is characterized by being provided with a polyhedron light distribution optical device 5 and a conductive supporting body 6, wherein the heat radiating block consists of a lower heat radiating block 3 and an upper heat radiating block 9 which are arranged and connected with the lamp holder 1 and the light transmission cover 7 into a whole; the LED light source is provided with a lower LED light source 4 and an upper LED light source 8; the lower LED light source 4 is fixed on the lower heat radiating block 3, and the upper LED light source 8 is fixed on the upper heat radiating block 9; the polyhedron light distribution optical device 5 is supported between the lower LED light source 4 and the upper LED light source 8 through the conductive supporting body 6; and the conductive supporting body 6 is electrically connected with the lower LED light source 4 and the upper LED light source 8. The invention has scientific and reasonable structure, convenient and fast production, manufacture, processing and assembly, low cost, excellent interchangeability, good integral artistry, attractive appearance and long service life.

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...
