Description

  The present invention relates to a lamp, and more particularly to a lamp using an LED as a light emitting device.

  LEDs are one of the products that have received the most attention in recent years. LED has advantages such as low pollution and high luminous intensity, and unlike conventional light emitting devices, LED is not easily scattered, so it is widely used for lighting fixtures that are often seen, but recently it is also used for traffic lights. became.

  Since traffic lights installed on roads are used to guide pedestrians and vehicles, the required quality is considerably high, unlike lighting fixtures used in ordinary homes. Since traffic lights are installed outdoors, they must provide the same light intensity under different weather conditions. Conventional traffic lights use a single light-emitting device as the light source, and the illumination range is expanded using the reflection of the lamp's bulk. However, the light emitted by the conventional light-emitting device is easily scattered and is reflected by the reflection of the lamp's bulk. It was difficult to concentrate. For this reason, there is a limit to the lighting effect, and when the weather is bad, if it is affected by fog, rain, etc., it becomes more blurry and the purpose as a traffic light cannot be achieved.

  The advantages of LEDs can make up for the disadvantages of conventional light emitting devices. The LED is one of the main light-emitting devices of traffic lights because it can accurately guide pedestrians and vehicles even when the weather is bad, as well as being difficult to scatter light rays.

  LEDs have the advantage that light rays are not easily scattered, but a large irradiation range is more important than a high luminous intensity for a traffic light. For this reason, a plurality of LEDs are arranged in two rows inside the conventional traffic light to improve the luminous intensity of the light source. In addition, a lampshade was placed inside the lamp, and it was condensed by reflection to expand the irradiation range.

In the prior art, a plurality of LEDs are used as light sources, and the light intensity is sufficient to provide a large irradiation area. However, the conventional lampshade structure was poorly designed, so the light emission of LEDs arranged in two rows The reflected light is completely reflected by the lampshade and is not irradiated, and as the light source intensity increases, the irradiation area cannot be increased. For this reason, the luminous efficiency of the traffic light cannot be increased as the light source intensity increases, but energy is wasted on the contrary, and a new method for improving the prior art has been awaited.

  An object of the present invention is to provide an LED lamp that uses a lamp unit including an LED as a light source and collects the light without scattering the light beam by improving the bending angle of the lampshade.

  In order to achieve the above object, the present invention provides an LED lamp. The LED lamp of the present invention includes a light seat. There is a recess recessed inward at the bottom of the lamp seat, and the inner edge surface of the recess has an arcuate surface, and the front and rear ends of the recess are curved toward the inside. The lamp units are arranged in a form in which three are arranged along the short side of the recess. The lamp unit uses an LED as a light-emitting device, and the lamp units at the left and right ends are inclined inward along the inner edge surface of the recess. Similarly, the lamp units at the front and rear ends of the same row are inclined inward along the inner edge surface of the recess. In addition to improving the luminous intensity of the LED lamp, the plurality of lamp units has solved the shortcoming of scattering of light beams by collecting the light beams of the plurality of lamp units.

  In the prior art, due to poor design of the lampshaft structure, the light emitted by the LED is not completely reflected and irradiated by the lampshaft, and the irradiation area cannot be increased with the increase of the light source intensity. However, the LED lamp of the present invention has been improved so that the angle of the lampshade is directed toward the center by utilizing the inclination of the recess recessed toward the inside of the light seat, so the irradiation area also increases as the light source intensity increases. It is possible to increase the light emission efficiency, improve the light emission efficiency, and overcome the disadvantage of wasting energy.
