Oil-cooling-method LED (light-emitting diode) lamp manufacturing method and LED lamp thereof

Abstract

The invention belongs to the field of LED (light-emitting diode) lamps, in particular to an LED lamp heat radiation method and a heat radiation structure thereof. An oil-cooling-method LED lamp manufacturing method comprises the steps: a paper substrate coated with clear coatings is placed between a light-transmitting lampshade and a sealing shell, and a power supply interface of the paper substrate is led out of the sealing shell; the light-transmitting lampshade and the sealing shell are sealed and fixed; paraffin oil is injected into the inner part of the sealing shell by virtue of an oil inlet; lamp beads of the paper substrate are powered on continuously by virtue of the power supply interface; the oil inlet is immediately closed off when the temperature of the paper substrate is raised to boil the paraffin oil; the cooled paraffin oil forms vacuum in the sealing space. An oil-cooling-method LED lamp comprises the sealing shell, the light-transmitting lampshade, the paper substrate and the lamp beads arranged on the paper substrate; each paper substrate surface is coated with one clear coating, a gap between the sealing shell and the light-transmitting lampshade is filled with the paraffin oil, and the coatings seal the whole paper substrate and insulate the paper substrate from the outside. The oil-cooling-method LED lamp manufacturing method and the LED lamp thereof have the advantages of simple structure, high heat radiation effect and low cost.

[0002] At present, most of the structures of LED lamps use aluminum substrates. Aluminum substrates have become a more commonly used substrate material. One of the reasons for its popularity in the market is that it has better heat dissipation performance. With the progress of society, aluminum substrates have shown certain disadvantages, such as the requirements of modern society for environmental friendliness, and the current situation of high cost. In the existing technology, the structure using paper substrates is mostly used in low-current and low-cost demand market, it cannot be used in the field of large current, one of the reasons is that its heat dissipation effect is not good

There are many ways to solve heat dissipation. Patent No. 201020110603.4 discloses a solution to use oil to cool the power supply of LED lamps. Under the requirement of good sealing of the power supply, it uses cooling oil for cooling, but based on the technology in this field As far as the personnel know, since the oil needs to expand with heat and contract with cold, there is room for thermal expansion without filling the inside of the power supply; although there is no specific mention of thermal expansion space, it can be easily known that this space was created before it was closed. Filled with air, and then sealed to form

Furthermore, in the technical solution, many details are not fully disclosed, and the actual use effect is unknown. For example, in actual use, if the cooling oil is directly filled, it will lead to insulation performance and carbonization of electronic components. ), the problem of poor airtight performance

At the same time, the problem of overall sealing has not been made public.
