Abstract

A glass heat pipe LED lamp with the surface provided with a titanium dioxide coating comprises a glass heat pipe, an LED, a drive power supply, an electrical connection interface and a control system, wherein the electrical connection interface is connected with the outside. The glass heat pipe LED lamp is characterized in that all parts of a pipe case of the glass heat pipe are connected into a whole in a seamless and melt sealing mode; more than 80% of the surface of the lamp is provided with the titanium dioxide coating which is continuous or discontinuous; the lamp comprises the ultraviolet LED which is independently turned on or off; the hot end surface of the glass heat pipe is connected with the LED in a heat transfer mode. The wall of the glass heat pipe is coated with the titanium dioxide photocatalyst coating, organic matter dirt making contact with the titanium dioxide coating is continuously decomposed into nitrogen, carbon dioxide, water and other micromolecules through light and ultraviolet of the lamp, and then the automatic cleaning effect is achieved; the heat pipe is made of high transparent glass, and more light can be reflected and transmitted to all the surface of the lamp for automatic cleaning.

Description

technical field [0001] The invention relates to a glass heat pipe LED lamp with a titanium dioxide coating on the surface. LED is the English abbreviation of laser light-emitting diode, which can be regarded as a professional term recognized in the technical field. Background technique [0002] The general structure of LED lamps using gravity heat pipes should be that the hot end under the heat pipe is connected to several LEDs for heat transfer. The main role played by the heat pipe here should be to realize heat flux density transformation and heat dissipation. The associated heat flux conversion is approximately from about 0.5 W / cm2 to about 0.06 W / cm2. [0003] Investigate the existing LED lamps. For one of the LEDs with a length*width of 5*7 mm, a total power of 0.6 watts, and a luminous efficiency of 21%, all energy except light emission enters the environment through surface conduction, and the entire surface area of ​​the LED is taken as 1 cm. 2 (0.5*0.7*2+0.1.25*...
