Description

LED lighting structure {LED ILLUMINATING STRUCTURE}

The present invention relates to an LED lamp, and more particularly to an LED lamp structure that blocks the light that is going to unnecessary parts and reflects the light, and excellent heat dissipation performance.

Recently, a light emitting diode (hereinafter, abbreviated as "LED element") including a semiconductor element is attracting attention as a light source of various lighting devices. Such LED elements have a low heat generation and long life compared with conventional lighting lamps such as incandescent lamps or halogen bulbs, and thus have been recently utilized in various fields as lightings for display and general lighting devices. In addition, the LED device generates light as a current passes through the junction boundary of the heterogeneous semiconductor, and the light is almost the same level as that of a conventional incandescent lamp or a halogen lamp.

The efficiency of the LED device is that the energy lost during the photoconversion process is converted to heat, which increases the temperature of the device. If the heat generated is not released to the outside, the LED device may be damaged and its life may be shortened rapidly. In particular, if the LED device is difficult to heat dissipation due to the difficult operating temperature conditions unlike the conventional lighting lamps, the heat generation per area is increased and the life of the parts is shortened.

Since the LED device emits light in a small area of several mm size, it is closer to the point light source than the conventional lighting light source. Therefore, when directly observing the light source of the LED element, severe glare occurs, so in order to alleviate this, a method using a diffuser plate or a lens having a wide radiation angle is widely used. However, when a diffuser plate is used, a lens is used. The glare is reduced than in the case. However, in the case of using a diffusion plate, since the diffusion plate absorbs light, energy efficiency is lowered, and in the case of using a lens, the cost is increased. In particular, in the case of using a diffusion plate, since the diffusion plate is generally provided on the front surface of the LED device, air circulation is blocked on the front surface of the LED device, which is disadvantageous in terms of heat dissipation. Therefore, other devices besides the lens and the diffuser plate should be sufficient to dissipate glare while generating heat radiation.

In addition, the light emitted from the LED element is often supplied with light in unnecessary parts, causing a waste of power. Since one or more LED elements are arranged in a line in one support frame, the angle of emitted light is fixed. There is a problem that it is hard to illuminate widely.

Korean Patent Laid-Open Publication No. 2009-0017941 discloses a lamp having a reflecting shade whose irradiation range is adjusted. As shown in FIG. 1, the lamp 10 includes a reflector 1, a light source 2, an operation bar 3, and a housing 4 composed of a plurality of rotating reflectors.
