Abstract
Provided is a bulb-type LED lamp 10 configured to diffuse light outward through a globe. The bulb-type LED lamp 10 includes LED modules 22, 24, 28, 30, each having a mounting substrate and LEDs mounted on the mounting substrate, and a base 14 through which power is supplied to the LEDs for light emission. The LED lamp 10 also includes a light diffusing member 58. Among the LED modules 22, 24, 28, 30, the LED module 22 is positioned on an imaginary extension of a central axis X of the base 14, and the light diffusing member 58 is positioned inside the globe 16 to receive light emitted from the LED module 22. The other LED modules 22, 28, 30 are positioned in a vicinity of the LED module 22, tilted to face the light diffusing member 58.
Claims8
An LED lamp for emitting light outward through a globe, comprising:
- a plurality of LED modules composed of one main LED module and one or more auxiliary LED modules, each of the plurality of LED modules having a mounting substrate and LEDs mounted on the mounting substrate;
- a base through which power is supplied to the LEDs for light emission;
- and
- a light diffusing member, wherein
- the main LED module is positioned on an imaginary extension of a central axis of the base, and the light diffusing member is positioned inside the globe such that the main LED module emits light towards the light diffusing member, and
- the one or more auxiliary LED modules are positioned in a vicinity of the main LED module, with at least one of the one or more auxiliary LED modules tilted to face the light diffusing member.
