Description

  The present invention relates to a lighting device, and more specifically, uses an LED (Light-Emitting Diode) element as a light source, prevents a decrease in the light output life of the LED element with a convection heat dissipation type frame that generates heat quickly, and reduces glare and light attenuation. Not uniform relates to the LED lighting device that illuminates.

  Recently, LED elements have been spotlighted as light sources for lighting devices. LED elements generate less heat than conventional illumination light sources, and have advantages such as low power consumption, long life, and impact resistance.

  In addition, there is an advantage that environmental pollution is not induced because it is not necessary to use mercury or a discharge gas like a fluorescent lamp in the manufacturing process.

  The LED element can maintain the lighting state without burning even if it is used for 100,000 hours or more when it provides appropriate power supply and heat generation means. All light sources have a gradual decrease in light output over time, but up to 80% of the initial intensity is undetectable by humans, so when evaluated on the basis of this, the lighting life of LED elements is currently around 40,000-5. It is expected to be 10,000 hours. Therefore, compared to the 1,500 hours of incandescent bulbs and 10,000 hours of fluorescent lamps, LED elements have a very long life and can be said to be a long-life light source.

  However, when the drive current is increased in the LED element to obtain a light source with high brightness and high output, the power loss of the LED element increases and most of the electrical energy is converted to heat, and the junction part of the LED element Becomes hot.

  This LED element has a characteristic that not only the light output and the light efficiency are lowered but also the operating life is reduced when the temperature of the junction portion is increased even if the flowing current is constant. Therefore, in order to improve the lighting performance and operating life, heat generated at the junction of the LED elements must be radiated to the outside as quickly as possible.

  In order to solve this problem, a high-brightness LED element is mounted on the front of an integrated metal housing (housing) that has a cooling structure with various cooling pins around the body. LED lighting lamps were manufactured with a diffusion cover. However, in such a method, the projection angle of the LED light source is narrowed, the light attenuation is increased due to the milky white diffusion cover and the illuminance decreases, and heat accumulation occurs inside the diffusion cover, and the LED element easily deteriorates. There were problems that the lighting hues varied and the service life was shortened.

  In addition, general bulb-type LED lighting lamps are combined into a single unit by being divided into a DC power source, a metal heat dissipation housing, a high-intensity LED element mounted on the front of the housing, and a milky white diffusion cover in the manufacturing process. Therefore, if the lighting intensity of the LED light source decreases, it is extremely difficult to replace the LED element and the DC power supply unit that are elaborately integrated in the metal housing. There was a problem of mass production and waste of resources.

  Further, the LED element is a point light source that emits light from a semiconductor element, and the light emitting surface of the LED element has a structure that collects and diverges light on the front surface using a small reflecting mirror and an epoxy lens. Therefore, when emitting light with high brightness to increase the degree of illumination, the glare of the light source becomes severe, so most LED lighting lamps can be covered with a milky white round diffusion cover on the LED element or eliminate the glare For this purpose, an irregular light reflector made of irregularly shaped irregularities was placed on the LED light source and used as an LED illuminating lamp.

  The milky white diffusing cover and the irregularly reflecting irregular reflection plate have the disadvantage that the illumination intensity is greatly reduced by attenuating the light quantity of the LED element due to the characteristics of the light diffusing material and the irregular reflecting structure. Therefore, in consideration of such a reduced light quantity, more high-intensity LED elements will be attached to the light source part, and by doing so, the heat generation amount must be doubled and the heat dissipation function must be further enhanced, so manufacturing There is a problem that the cost of the LED lighting device is increased due to a significant increase in cost.

  On the other hand, convective heat dissipation is to dissipate the heat generated from the device using the convection phenomenon of air, and after the cold air that has flowed into the lower part of the device is heated by internal heat, it escapes to the upper part by natural convection. This means that overheating of the device is prevented.

  The present invention has been devised to solve the above-mentioned problems, and one embodiment of the present invention affects the light output and life of the LED device through a lamp-type frame having a convection heat dissipation structure with smooth ventilation. LED-type LED lighting device that quickly releases the heat generated by the LED element and eliminates the dazzling phenomenon of the LED light source by using the side reflection member, diffuser lens and diffuser cover, and diffuses the light source widely without light attenuation Is to provide.

  In optics, total reflection is a phenomenon in which light incident at an incident angle greater than a specific critical angle is reflected 100% without being refracted when light travels from a material with a high refractive index to a material with a low refractive index. In other words, the minimum value of the incident angle at which total reflection can occur is called the critical angle. For example, the critical angle when light exits from the glass to the air is 42 °, and if the critical angle is larger than this, the light cannot be transmitted through the glass and all is reflected 100% to the inner surface of the glass and exits toward the air.
