LED lamp bulb with multi-direction projection effect

Abstract

The invention discloses a light emitting diode (LED) lamp bulb with a multi-direction projection effect. The LED lamp bulb comprises a lamp shade, a heat-conducting base, a plurality of radiating fins, a heat-conducting component and a plurality of LED light-emitting components, and is characterized in that: the plurality of radiating fins are combined at the periphery of the heat-conducting base; the heat-conducting base is provided with a middle hole in which the heat-conducting component can be accommodated in an interference fit mode; a plurality of inclined surfaces and a top surface are formed at the exposed end of the heat-conducting component by stamping, or a flat-top cone with a polygonal inclined surface and a top surface is formed at the exposed end of the heat-conducting component by stamping; one or more LED light-emitting components are attached to and combined on the inclined surfaces and the top surface respectively; the plurality of LED light-emitting components at different angles can achieve the multi-direction projection effect, so that illuminating brightness is improved; and the heat of each LED light-emitting component directly and concentratedly passes through the heat-conducting component, and is quickly released by the plurality of radiating fins, so that the lamp bulb cannot be damaged due to overheating.

Description

technical field [0001] The invention relates to the improvement of an LED light bulb, in particular to a design of an LED light bulb with multi-directional projection and excellent heat dissipation function. Background technique [0002] Conventional LED light bulbs, because the internal LED light-emitting components are all facing the front end, so the light sources are concentrated and projected in the same direction at the front end, the peripheral light sources will be relatively weak, and the brightness is likely to be insufficient, and the overall lighting brightness is uneven. Although it has the advantage of low power consumption, it has low heat resistance, so the problem of heat dissipation must be solved; for example, the LED light bulb manufactured by Philips is known to use a molded metal heat sink to provide heat dissipation, but the overall Bulky and expensive, the heat dissipation effect is very limited, and it is not practical. [0003] According to the rec...

[0002] Conventional LED light bulbs, because the internal LED light-emitting components are all facing the front end, so the light sources are concentrated and projected in the same direction at the front end, the peripheral light sources will be relatively weak, and the brightness is likely to be insufficient, and the overall lighting brightness is uneven. Although it has the advantage of low power consumption, it has low heat resistance, so the problem of heat dissipation must be solved; for example, the LED light bulb manufactured by Philips is known to use a molded metal heat sink to provide heat dissipation, but the overall Bulky and expensive, the heat dissipation effect is very limited, and it is not practical

[0003] According to the recent development trend, the light bulbs of ordinary LED or high-power LED light-emitting components have gradually replaced the traditional tungsten filament heating bulbs, and the related technology is also constantly improving. Heat dissipation by conduction, after a long time of use, the accumulated temperature will rise, which will easily cause poor electrical properties or damage to the LED, especially as the number of LED light-emitting components increases and the temperature increases relatively, the heat dissipation problem it faces will become more serious
