Description

LED light emitting device

technical field

The present invention relates to a light emitting device, in particular to a light emitting diode (LED) light emitting device having a convective heat dissipation type structure capable of rapidly dissipating heat, by using an LED element as a light source, it is possible to prevent deterioration of the light output and lifetime of the LED element and Emit uniform light without glare and light attenuation.

Background technique

In recent years, LED elements have been used as light sources of various light emitting devices in spotlights. Compared with known light sources, LED elements have advantages such as low heat generation, low energy consumption, long life, high impact resistance and the like. Also, in the production process, since mercury or discharge gas is not used like fluorescent lamps, LED elements have the advantage of not causing environmental pollution.

Under the condition that the LED element is provided with suitable energy and suitable heat dissipation components, the LED element can be used for 100,000 hours or more without any damage even though it maintains a luminous state. But the light output of all light sources gradually decays over time. Since one cannot perceive the difference when the luminous intensity becomes 80% of the original luminous intensity, the lifetime of the light-emitting LED element is currently expected to be about 40-50 thousand hours. Therefore, an LED element may have a much longer life than an incandescent lamp with a life of 1500 hours and a fluorescent lamp with a life of 10,000 hours.

However, when the driving current of the LED element is increased in order to obtain high brightness, the energy loss of the LED element increases due to a high-power light source. As a result, most of the electric energy is converted into heat, and the junction part of the LED element is at a high temperature. state.

Even if the current flowing through the LED element is constant, when the temperature of the junction portion increases, the LED element has such characteristics that the light output and light efficiency deteriorate, and its operating life is shortened accordingly.

Therefore, in order to improve luminous performance and luminous lifetime, the heat emitted from the junction portion of the LED element must be dissipated to the outside as quickly as possible.

In order to solve this problem, in related technologies, high-brightness LED components are installed on the front surface of an integrated metal housing, on which heat dissipation fins are formed around the main body in a variety of heat dissipation structures, semicircular ivory-colored A diffusion cover is covered on it to prepare an LED light emitting lamp. However, such a configuration has problems in the emission angle of the LED light source. Due to the effect of the ivory white diffusion cover, the light attenuation increases, reducing the light emission, and heat accumulation occurs on the diffusion cover, which is easy to make the LED components degrades, and thus changes the color of the light emitted, or shortens its lifetime.

Moreover, the conventional spherical LED light-emitting lamp has such a problem because a DC power supply and a metal heat-dissipating case, a high-brightness LED element mounted on the front surface of the case, and an ivory white diffusion cover are all in the manufacturing process Integrated together, when the luminescence of the LED light source deteriorates, the LED element and the DC power supply integrally and carefully mounted on the metal case are very difficult to replace, and as a result, the entire product is usually discarded, thus generating garbage and wasting resources .

Also, the LED element is a point light source that emits light in a semiconductor element, and its light emitting surface has a structure that collects light at its front surface and scatters the collected light by using a small reflective mirror and an epoxy lens. Therefore, when the LED element is made to emit high-intensity light in order to increase brightness, the light source will be extremely dazzling. Therefore, in order to prevent glare, most of the LED light-emitting lamps cover the LED elements with an ivory white circular diffuser cover, or cover the LED light source with a diffuse reflection plate made of a translucent material with irregular and non-uniform curved surfaces. LED light.

The ivory white diffusion cover or the irregular and non-uniform diffusion reflection plate reduces the light quantity of the LED element, and due to the characteristics of the light diffusion material and the diffusion reflection structure, the brightness is obviously reduced. Therefore, an additional high-brightness LED element is mounted on the light source portion in consideration of the reduced amount of light, and as a result, the amount of emitted heat is also multiplied. Therefore, in order to meet its needs, the heat dissipation function must be further improved. Therefore, the manufacturing cost is greatly increased, and the LED light emitting device becomes expensive.

Meanwhile, convective cooling prevents the device from cooling by removing the heat generated in the device by utilizing the convection phenomenon that cold air introduced into the bottom of the device is heated by the heat inside the device and then discharged from the top by natural convection. overheat.
