Problems solved by technology
[0002] At present, with the high-power and high-brightness white LED light source has gradually replaced the traditional light source, but its disadvantage is that the problem of high junction temperature of the LED cannot be effectively solved, resulting in a decrease in the luminous efficiency of the LED chip, fast light attenuation, aging, and shortened service life. The problem has always prevented high-power LED lamps from being used in the field of street lighting with high illuminance, harsh use environment, and long life requirements.

Description
technical field [0001] The invention relates to a heat dissipation device for a lamp which utilizes the vaporization of a liquid medium to absorb heat and cool down, in particular to a heat dissipation device for a lamp with a high-power light-emitting diode light source. Background technique [0002] At present, with the high-power and high-brightness white LED light source has gradually replaced the traditional light source, but its disadvantage is that the problem of high junction temperature of the LED cannot be effectively solved, resulting in a decrease in the luminous efficiency of the LED chip, fast light attenuation, aging, and shortened service life. The problem has always prevented high-power LED lamps from being used in the field of street lighting with high illuminance, harsh use environment, and long service life. With the needs of LED green lighting and energy-saving situation, the development of high-brightness, high-power LED light source lamps suitable for ...
