Embodiment Construction

[0051] For convenience and clarity of description, the thickness or size of each layer may be exaggerated, omitted, or schematically shown. The size of each component may not necessarily represent its actual size.

[0052] It will be understood that when an element is referred to as being "on" or "under" another element, it can be directly on / under the element, or one or more intervening elements may also be present. When an element is referred to as being "on" or "under", "under the element" as well as "on the element" may be included based on the element.

[0053] Embodiments can be described in detail with reference to the accompanying drawings.

[0054] figure 1 is a cross-sectional view of a lighting device according to an embodiment.

[0055] refer to figure 1 , the lighting device according to this embodiment may include a main body 100 , a light source module 300 , a reflector 500 and an optical exciter (optical exciter) 700 . Hereafter, the following detailed des...

Abstract

A lighting device may be provided that includes: a light emitting device; and an optical exciter which is disposed over the light emitting device and emits light excited by the light emitted from the light emitting device. The optical exciter includes at least one of a yellow fluorescent material, a green fluorescent material and a red fluorescent material. The optical exciter moves over the light emitting device. A color temperature of the light emitted from the optical exciter varies according to the movement of the optical exciter.

Description

technical field [0001] Embodiments may relate to a lighting device. Background technique [0002] LEDs generate a lot of heat when turned on. If the heat cannot be dissipated quickly, it will shorten the life of the LED and reduce the illuminance of the LED, and the quality characteristics will be significantly deteriorated. [0003] White light emitting device packages are now being increasingly used as light sources for lighting devices. Recently, the concept of so-called emotional lighting has emerged. In this way, a cool white light source with a high color temperature and a warm white light source with a low color temperature are selected and used according to user's preference and usage. Contents of the invention [0004] technical problem [0005] The embodiment provides a lighting device capable of satisfying various optical needs. [0006] The embodiment provides a lighting device capable of controlling color temperature. [0007] Embodiments provide a light...
