Abstract

The utility model discloses a heat radiating panel of an LED (light-emitting diode) lamp, which comprises a metal plate and heat pipes, wherein the middle of the upper end of the metal plate is provided with a circular pit; the lower end is respectively provided with two parallel heat pipes which are longitudinally and horizontally outward; and heat-conducting media are respectively arranged in the heat pipes. The heat radiating panel has simple structure and obvious heat radiating effect, is convenient to install, can be widely applied to various LED lamps, particularly the high-power LED lamps, and has enormous market value.

Description

The LED light heat radiation board

Technical field

The utility model relates to a kind of LED lamp parts, especially a kind of LED light heat radiation board.

Background technology

As everyone knows, the LED lamp is the same with conventional light source, duration of work can produce heat, the LED lamp is adding under the energy, the radiation recombination in electronics and hole and the electricity that takes place cause effect the 30-35% of energy are converted into luminous energy, but not the lattice vibration that radiation recombination takes place is converted into heat with the 65-70% of energy.LED is very sensitive illuminating part to temperature, under the lower situation of operating temperature, just can obtain high reliable optical index, could satisfy the instructions for use of illumination usually.

In order to make the LED lamp can be suitable for the demand of illumination usually, the solid-state illumination light source presses for the problem that solves the unit light flux, the increase of LED lamp unit light flux and make every unit caloric value significantly increase, and rolling up of heat makes the led chip decay of luminescence and loses use value, therefore, how to solve and dispel the heat particularly that high-power LED lamp is a present big technical barrier.

The utility model content

At the weak point that prior art exists, the purpose of this utility model provides a kind of have remarkable radiating effect and LED light heat radiation board simple in structure, easy for installation.

For achieving the above object, the utility model is realized by adopting following technical proposals: a kind of LED light heat radiation board, comprise metallic plate and heat pipe, the upper center of described metallic plate is provided with a circular pit, and the lower end vertical and horizontal all are equipped with two heat pipes that be arranged in parallel laterally; Heat-conducting medium all is housed in the described heat pipe.

The beneficial effects of the utility model are: owing to adopt said structure, be pit that is provided with on the metallic plate and the heat pipe that heat-conducting medium is housed, the heat that can effectively in time the LED lamp be produced distributes with the outside heat radiation object that is connected by the heat pipe tail end, thereby can reduce the operating temperature of LED lamp, make it work in optimum state.The utility model is simple in structure, easy for installation, have significant radiating effect, can be widely used on the various LED lamps, and especially high-power LED lamp has huge market value.
