Description

  The present invention relates to a high-efficiency LED lamp. More specifically, the present invention not only provides excellent heat dissipation and electrical insulation effects, but also requires a high bulb that can be assembled by replacing only the bulb without replacing the entire lamp. It relates to an efficient LED lamp.

  LED is an abbreviation for light-emitting diode and is a solid-state light-emitting element made of a semiconductor material. As a material, a group III-V element (for example, gallium phosphide (GaP) or gallium arsenide (GaAs) is used. The light emission principle is to exchange electrical energy for light, and by applying an electric current to the compound semiconductor, the excess energy is released as light by the combination of electrons and holes, and light emission An effect is obtained, which belongs to low-temperature light emission and has a lifetime of 100,000 hours or more.The biggest feature of LED is that it does not require idling time, has a quick reaction, and has a small volume. Power saving, earthquake resistant, low pollution, suitable for mass production, high reliability and very small elements and array type elements as required The advantage is that it can be manufactured.

  However, since the LED is solid-state lighting, energizing the chip causes the quantum to be in an excited state and releases energy (light). However, in the process of light emission, the light energy in the chip is externally applied. The energy of light that is not transmitted completely to the outside and is not emitted to the outside is absorbed inside the chip and in the package to form heat. In general, since the conversion efficiency of LEDs is about 10% to 30%, less than 0.2W is converted to visible light with 1W of power, and the rest becomes heat and if not dissipated, the amount of heat Accumulates and adversely affects chip efficiency and lifetime.

  Therefore, when applying highly efficient LED to lighting equipment, first, the problem of heat dissipation must be solved. A conventional heat dissipation structure for a high power LED bubble is mainly configured such that a base substrate is fixed to a base, and at least one heat pipe is supported and fixed on the upper surface of the base substrate. An upper substrate is fitted and a high power LED corresponding to the number of heat pipes is provided on the upper surface of the upper substrate, and the bottom surface of the high power LED is supported by the upper end of the heat pipe.

  The heat dissipation module of the light emitting diode package includes an LED circuit board, a heat dissipation block having a plurality of heat dissipation fins, and a heat dissipation rubber for fixing the LED circuit board on the heat dissipation block. The LED circuit board And a metal substrate is installed between the heat dissipating block. In addition, there is a high heat radiation light emitting diode provided with a porous material layer, a heat conductive layer formed on the surface of the porous material layer, and the heat conductive layer on which a chip is installed. Thus, the amount of heat generated from the chip is conducted to the porous material layer, and the amount of heat is radiated to the outside by convection in the porous material layer.

As described above, the heat radiation of a conventional LED is performed by using a metal heat radiation fin or by connecting a heat pipe, a cooling chip, a heat equalizing plate, a heat radiation fan, etc. There are still problems such as no heat dissipation, slow heat dissipation, complicated heat dissipation module structure, high cost, and difficult to meet the safety standards for electrical insulation, and the heat dissipation structure to be used is standardized design Because it is not, you have to design a special lamp.
As described above, since there are a number of drawbacks in the existing technology, it is an urgent task to eliminate these drawbacks.

Under such circumstances, according to Patent Document 1, it is disclosed to use a power distribution module having radial heat dissipation fins as a heat dissipation function.
However, even in such a proposal, it is pointed out that there are still structural problems and that heat dissipation efficiency should still be solved.
