Title:
LIQUID-COOLED LAMP
Document Type and Number:
WIPO Patent Application WO/2016/026405
Kind Code:
A1
Abstract:
A liquid-cooled lamp, comprising a lamp base (1), a lamp core (2) electrically connected to the lamp base (1) and a lamp shell (3) covering the lamp core (2) and hermetically connected to the lamp base (1); the lamp shell (3) is filled with insulative and heat conductive liquid (4); the lamp core (2) is immersed into the insulative and heat conductive liquid (4), and comprises lamp strings (21) or filaments (22) comprising lines of serially connected multiple semiconductor light sources. The multiple semiconductor light sources are small semiconductor light sources being small LED lamp beads (211) or light-emitting PN-junction chips (221); the plurality of small LED lamp beads (211) or light-emitting PN-junction chips (221) are connected in series and are packaged with transparent materials to form lamp strings or filaments. The light direction of each of the lamp strings (21) or filaments (22) in the liquid cooled lamp can be adjusted individually to enable the light of all lamp strings (21) to be radiated, providing uniform brightness in all directions, thus not only increasing a heat conductive area but also dissipating heat uniformly, and fully utilizing the effect of the insulative and heat conductive liquid and extending the service life of the liquid cooled lamp.
