An omnidirectional led bulb light

Abstract

The invention discloses an omnidirectional LED bulb lamp which comprises a lamp holder, a power supply cover, a radiator, an LED light source module and a power supply arranged in the power supply cover. The radiator comprises a hollow radiating base and at least three radiating blocks which take the top end face of the radiating base as a starting point, are evenly arranged in an annular array mode and extend upwards, a radiating channel communicated with an inner cavity of the radiating base is arranged in each radiating block and extends downwards from the top end of the radiating block, a light source mounting seat is arranged between each two adjacent radiating blocks and provided with an upper mounting tabletop and a lower mounting tabletop, each upper mounting tabletop is inclined outwards from top to bottom, and each lower mounting tabletop is inclined outwards from bottom to top. The omnidirectional LED bulb lamp has the advantages that the omnidirectional LED bulb lamp is simple in structure, a plurality of light source mounting seats are circumferentially evenly distributed, each light source mounting seat is provided with two inclined mounting tabletops, accordingly, light emitted by the LED light source module can meet the requirement of American Standard Energy Star on omnidirectional light intensity distribution, and radiating effects can be effectively improved as the chimney effect can be achieved by communication of the radiating channels with the inner cavity of the radiating base.

Description

technical field [0001] The invention relates to a lamp, in particular to an omnidirectional LED bulb lamp. Background technique [0002] With the rapid development of LED lighting technology, more and more places use LEDs as lighting sources. In order to reduce waste, LED bulb lamps that replace traditional incandescent lamps for indoor lighting have also emerged one after another by using existing interfaces. For American Standard LED bulbs, American Standard Energy Star released a new standard for LED lighting at the end of 2009, which stipulates the light intensity distribution of omnidirectional lights (also known as non-directional lights). In this standard, when the LED bulb is directly below 0 degrees, within the range of 135 degrees on both sides, the luminous intensity at any angle must not be lower than or higher than 20% of the average luminous intensity, and at 135 degrees In the range of ~180 degrees, the luminous flux must reach at least 5% of the total lumin...

Problems solved by technology

Most of them use special lens light distribution, that is, on the basis of the existing LED lamps, the omnidirectional light intensity distribution is realized by installing upward astigmatism lenses on the surrounding LED lamp beads. Although the LED bulb lamp with this structure can In terms of light intensity distribution, it meets the requirements of the American Standard Energy Star for omnidirectional light intensity distribution, but due to the difference in the refractive index of different colors, it is easy to produce inconsistency in light color temperature, resulting in visual fatigue; on the other hand , because there will be light loss in the secondary light distribution, which will reduce the light effect of the whole lamp, so the LED bulb lamp with this structure can generally only replace the low-power incandescent lamp
