Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the drawings and embodiments. It should be noted that, if there is no conflict, the embodiments of the present invention and various features in the embodiments can be combined with each other, and all fall within the protection scope of the present invention.

[0021] The present invention provides a heat-dissipating composite oil, which is used in LED liquid lamps that use liquid heat to dissipate as a medium for accelerating heat dissipation. The heat-dissipating composite oil includes: silicone oil and diffusing powder. The proportion of silicone oil is 90% to 98%, and the proportion of diffusing powder is 2% to 10%. The heat dissipation compound oil here needs to have the functions of insulation, heat dissipation, explosion-proof, and optical diffusion effect. The heat-dissipating composite oil adopts a temperature-sensitive diffusion powder with optical diffusion function added to the silico...

Abstract

The invention discloses cooling compound oil and an LED liquid lamp, and relates to the technical field of light source illumination. The cooling compound oil is used for cooling an LED photoelectric module during working. The cooling compound oil comprises silicone oil and dispersion powder, wherein the ratio of the silicone oil is 90-98%, and the ratio of the dispersion powder is 2-10%. According to the cooling compound oil and the LED liquid lamp, as depowered high-power LED photoelectric module is dipped in the cooling compound oil, when the LED photoelectric module 150 works, the convection speed of upper and lower layers of compound cooling oil is fast, generated heat is quickly taken away, and meanwhile, the optical diffusivity is excellent.

Description

Technical field [0001] The invention relates to the technical field of light source lighting, in particular to a heat dissipation composite oil and an LED liquid lamp Background technique [0002] When the LED lamp is working, 70% to 80% of the energy is converted into heat, which leads to an increase in junction temperature and performance degradation. With the increase of power, the problems caused by heat have become more prominent, so it is of great significance to design the heat dissipation of lighting products. The heat dissipation design of LED indoor lights with a power of no more than 10W is based on metal radiators, which are called bulb lights. However, the additional metal radiator increases the cost of the bulb lamp, resulting in a higher price than traditional lamps, which is difficult for users to accept; and the thermally conductive silicone grease layer between the metal radiator and the aluminum substrate also affects the heat dissipation effect of the lamp. ...
