Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying 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 are within the protection scope of the present invention.

[0022] The invention provides a heat dissipation composite oil, which is used in an LED liquid lamp adopting liquid heat dissipation as a medium for accelerating heat dissipation. The heat-dissipating composite oil includes: silicone oil and diffusion powder, the silicone oil accounts for 90% to 98%, and the diffusion powder accounts for 2% to 10%. The heat-dissipating composite oil here must have the functions of insulation and heat dissipation, explosion-proof, and optical diffusion effect. Heat-dissipating composite oil uses temperature-sensitive diffusion powder with optical diffusion function added to the silicone oil, ...

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, resulting in an increase in junction temperature and a decrease in performance. With the increase of power, the problems caused by heat become more and more prominent, so it is of great significance to design the heat dissipation of lighting products. The heat dissipation design of LED indoor lamps with a power not exceeding 10W is mainly a metal radiator, which is called a bulb lamp. However, the additional metal radiator increases the cost of the bulb lamp, making its price higher than that of traditional lamps, which is unacceptable to users; and the heat-conducting silicone grease layer between the metal radiator and the aluminum substrate also affects the heat dissipation effect of the lamp.
