Embodiment Construction

[0013] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0014] like figure 1 As shown, a heat dissipation device for LED lighting fixtures has a heat dissipation plate as an aluminum substrate for LED chips. 1 stores a cold medium 2, and the two ends of the inflation tube 1 are connected to the heat pipe 3 through an elbow. The heat pipe 3 is located above the inflation plate, and the LED is directly pasted below the inflation plate. Chip 4.

[0015] The working principle of the present invention is: when the liquid refrigerant at the bottom of the expansion plate encounters a heat source (the LED is powered on), it will become a vapor state, and the change of this state will t...

Abstract

The invention relates to a radiating device of an LED (light emitting diode) lighting fixture. The radiating device is provided with a radiating plate for an LED chip aluminum base plate; the radiating plate is a blown plate; the blown part of the blown plate forms a blown pipe; a refrigerant medium is stored in the blown pipe; two ends of the blown pipe are communicated with a heat conduction pipe through a bend pipe; the heat conduction pipe is arranged above the blown pipe; and an LED chip is directly pasted below the blown plate. According to the invention, the LED chip is directly adhered to the blown plate or an extruded aluminum of the heat conduction pipe by utilizing a refrigerant low-temperature evaporation principle, thus heat is instantly evaporated, conducted and dissipated when the LED chip works, the cost is low, the heat is dissipated efficiently, and the service life of the LED is prolonged.

Description

technical field [0001] The invention relates to the technical application field of LED lighting appliances, in particular to a heat dissipation device for LED lighting fixtures. Background technique [0002] At present, for the consideration of saving energy, LED lighting fixtures have been and are being widely used in various lighting occasions. It is generally believed that the emergence of LED lighting fixtures is a revolution in the field of lighting. [0003] There are two major obstacles to the widespread use and popularization of LED lighting fixtures: one is that the cost is too high; the other is that the light decays seriously. At present, the heat dissipation structure of existing LED lighting fixtures on the market is generally adopted: the LED chip is pasted on a special aluminum substrate, and the aluminum substrate is connected with various heat dissipation structures and materials, and some of them are coated with heat-conducting coatings. Silicone grease, ...
