Abstract

The invention discloses an LED (Light Emitting Diode) lamp with an LED directly connected with a glass heat tube in a heat transfer manner. The LED lamp comprises the glass heat tube, the LED, a driving power supply, an external electronic connecting interface and a control system. The LED lamp is characterized in that the surface of the hot end of the glass heat tube is matched with the surface of the LED and the LED is directly connected with the hot end of the glass heat tube in the heat transfer manner. According to the LED (Light Emitting Diode) lamp with the LED directly connected with the glass heat tube in the heat transfer manner, as the hot end of the glass heat tube is directly connected with the LED, the link of heat transfer through the base is eliminated. Under the condition that the heat is directly radiated through the cold end of the glass heat tube, the shortest heat transfer ways from the LED to the environment only comprise a heat transfer adhesive or an elastic heat transfer film between the LED and the glass heat tube, and the glass heat tube. By making wrinkles at the cold end of the glass heat tube, the heat radiation area is increased greatly, and then the requirements on the heat radiation area of a heat radiator can be met. Glass is stable in property, high in weather resistance and good in air tightness. When the heat tube is made of high-transparency glass, novel visual experience, such as lighting effect of a crystal chandelier, can be obtained.

Description

technical field [0001] The invention relates to LED direct heat transfer glass heat pipe LED lamps. LED is the English abbreviation of Laser Light Emitting Diode, which can be regarded as a recognized professional term in this technical field. Background technique [0002] The general structure of an LED lamp using a gravity heat pipe should be that the hot end under the heat pipe is connected to several LEDs for heat transfer. The main role of the heat pipe here should be to achieve heat flux density conversion and heat dissipation. The associated heat flux density transforms approximately from about 0.5 watts / cm 2 to about 0.06 watts / cm 2 . [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, a luminous efficiency of 21%, and all the energy other than the luminescence is conducted into the environment through the surface, the total surface area of ​​the LED is 1 cm 2(0.5*0.7*2+0.1.25*(7+5+7+5)), t...
