However, this still cannot effectively prevent a part of the light emitted by the fluorescent material from passing backwards, because the refractive index of the fluorescent layer and the transparent spacer are almost the same

Embodiment Construction

[0035] The present invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. The same reference numerals in the drawings denote the same elements, and the dimensions of the elements may be exaggerated for convenience and clarity of illustration.

[0036] figure 1 is a cross-sectional view illustrating a lampshade 10 of a light emitting diode (LED) lamp according to an embodiment of the present invention. Such as figure 1 As shown, the lampshade 10 includes a first lamp cap 1 having a convex outer surface, a second lamp cap 2 mounted on the first lamp cap 1 at a predetermined distance from the first lamp cap 1 and having a convex outer surface, and a filling A wavelength conversion layer 3 between the first lamp cap 1 and the second lamp cap 2 .

[0037] The first lamp cap 1 and the second lamp cap 2 have a concave-convex structure, such as figure 1 shown. That is, the first lamp cap 1...

Abstract

A lamp cover including a phosphor material therein and a light emitting diode (LED) lamp in which the lamp cover is mounted. The lamp cover includes: a first lamp cap having a convex outer surface; a second lamp cap that is coupled to the first lamp cap at a distance from the first lamp cap and has a convex outer surface; and a wavelength-conversion layer filled between the first lamp cap and the second lamp cap. Accordingly, luminance of the LED lamp using the lamp cover may be increased since light loss is relatively small.

Description

technical field [0001] The present invention relates to a lampshade and a light emitting diode (LED) lamp using the lampshade, and more particularly to a lampshade including a fluorescent material disposed therein and an LED lamp installed with the lampshade. Background technique [0002] Various types of light emitting diode (LED) devices that can emit light of various colors have been developed. Also, various methods of manufacturing lighting lamps providing white light by using LED devices have been proposed. For example, white light is typically formed by using light-emitting materials, such as fluorescent materials. For example, one example of the fluorescent material may be a fluorescent material that partially absorbs at least a portion of blue light emitted by the LED device to emit yellow light or yellow-green light. [0003] A general white LED package based on fluorescent material is formed by mixing fluorescent material with silicone encapsulation material, and...
