Description

LED lighting devices

The present invention, more particularly, to LED (Light-Emitting Diode) in the device used as a light source, radiating a rapid convection bangyeolhyeong frame to prevent the glare and light attenuating the light output of the LED device and reduced service life of about the illumination device It relates to an LED lighting apparatus that make a uniform light without.

LED element as a light source of the recent variety of lighting device has been spotlighted. LED element is less heat generation than the conventional illuminating light source, and has the advantages such as lower power consumption and longer life, the impact resistance. In addition, there is an advantage not because it does not use mercury or discharge gas causing environmental pollution such as fluorescent lights in the manufacturing process.

LED element can also maintain the lighting state without damage by using the time when more than 100,000 to provide the appropriate power supply and the heat dissipation means. All the light source is to over time decreases the light output gradually, because up to 80% of the initial brightness person not feel well is Cho Myeongyong service life of the LED element when evaluated in this standard is expected to present the 40,000 ~ 50,000 hours. Thus, the incandescent lamp 1,500 hours, LED devices compared to the more than 10,000 hours of fluorescent light may be referred to as a light source of a very long life, Jang Sumyeong.

If, however, increases the drive current to the LED element to obtain a high-brightness and high-power light source for illumination, the power loss of the LED element increases convert most of the electrical energy as heat, and minutes junction of the LED is a high-temperature state.

The LED device even when the flowing current is constant do have reduced properties of the joint portion temperature only will increase the light output and optical efficiency decreases when not operating life. Therefore, it should in order to improve lighting performance and operating life as fast as possible the heat generated in the bonding part of the LED emission to the outside.

Conventionally, to prepare a LED lighting lamp ssuiwoseo a milky white diffusion cover semicircular mounting the high-intensity LED element in a one-piece metal housing (housing) front portion formed from a variety of heat-radiating structure of cooling fins on the periphery, and over that of the main body to fix it . However, this approach is becoming narrower and the projection angle of the LED light source, as well as decrease the optical attenuation is large, illumination by a milky white diffusion cover up the heat accumulated inside the diffusion cover is an LED device easily deteriorated illumination color is changed or the service life there is a problem that is shortened.

Further, Common compact LED lighting lamp when separated during the manufacturing process with a high luminance LED element, a translucent white diffusion cover mounted on the front of the DC power source, a metal material heat the housing, the housing doemeuro bonded integrally, the jomyeongdo of the LED light source degradation metal housing the replacement of the finely equipped with LED elements and an integrated DC power supply is very difficult to dispose four Appliances Stocks mostly because there is a problem that the whole mass of rubbish and waste of resources.

In addition, the LED element is a point light source emitting light in a semiconductor element, a light-emitting surface of the LED element has a structure for collecting the light emitted to the front by using a small reflecting mirror and an epoxy lens. Therefore, to emit light with high luminance in order to increase the jomyeongdo severe glare of the light source, most of LED lighting lamps I of translucent material having a irregular curved in concave-convex shape in order to cover the like diffusion cover a circle having a translucent white on the LED element, or eliminating the glare ssuiwoseo the reflecting plate over the LED light source was used as the LED lamp.

Of the milk-white diffusion cover or irregular uneven structure I reflector has a disadvantage to attenuate the amount of light of the LED element characteristics of a light-diffusing material and diffuse structure to break down the larger jomyeongdo. Therefore, this is to mount a more high-intensity LED element in view of the reduced amount of light to the light source, so that heat generation is also doubled, so further increase the heat radiation function. The production costs are much higher there is a problem in that the LED lighting device gogahwa.
