Description
Using Method and Application of Light Conduction and Heat Dissipation Liquid in Liquid-Cooled LED Lighting Lamp Technical Field The invention relates to the technical field of LED lighting lamps, in particular to a using method of a light conduction and heat dissipation liquid in a liquid-cooled LED lighting lamp, and further to application of said using method.
Background LED is known as the fourth generation of lighting source or green light source, has the characteristics of energy conservation, environmental protection, long service life, small size, etc., and can be widely applied to various fields of indication, display, decoration, backlight, general lighting, urban nightscape, etc. In the field of lighting, application of LED
lighting products are attractive to the world's attention, as a new green lighting products, LED
must be the trend of development in the future, and people will enter a new lighting era which is represented by LED in the 21st century.
Heat-dissipation problem of LED has been solved in virtue of traditional aluminum fins in the existing LED lighting lamp, which causes an unavoidable problem that the lighting lamp with aluminum fins for heat dissipation can only emit light with a light-emitting angle of 1800; if a larger light-emitting angle is required, the light-emitting circuit board is to be used vertically, and it is difficult for heat dissipation, and the rest area is turned to be dark for being shielded by aluminum fins, such that spherical light exhibited by the lighting lamp is suppressed, and it is difficult to achieve aesthetic value of such bulbs when used in crystal lamps or other decorative lighting fitting;
in addition, many lighting lamps of the lighting fitting are mounted upwards, which makes large dark area in the lower area requiring lighting, the lower area requiring lighting can be lightened only by the light reflected from the wall, and the utility is largely decreased.
The structure of aluminum fin for heat dissipation is in a channel-type heat dissipation form. To control the junction temperature of LED chips, it is necessary to make heat conduction channel well from wafer to surface of the aluminum fin, but combination of various materials produces much thermal resistance, which limits construction of this heat-conducting channel, and cost must be increased in really making perfect heat conduction channel among these links, and the effect is not likely to be perfect. Some lighting lamps employ light-emitting bars to achieve three-dimension light pattern, which also leads to narrowing of the heat conduction channel.
In order to achieve spherical light, size of heat sinks is further reduced such that the lamp in this light-emitting form
