Abstract
The utility model discloses an LED lamp device with a heat radiation function which comprises a lamp, wherein the lamp is internally provided with a power supply device, a heat radiating plate is arranged below the power supply device, a PCB (printed circuit board) is arranged below the heat radiating plate, and the PCB is connected with an LED light source through heat conducting glue, and a lamp body is provided with a round vent hole. The LED lamp device with the heat radiation function has simple structure, is made of materials commonly used in industry, and has the characteristics of heat radiation, low cost and the like.
Description
Technical field
The utility model relates to a kind of LED lamp device, is specifically related to a kind of heat sinking function LED lamp device that has.
Background technology
The led light source product saves money than incandescent lamp power saving 90% again because of it is energy-conservation, and the life-span is 50 times of conventional bulb, and price is that the 50%LED of highly sophisticated products of the same trade is photoelectric devices, and grow and enjoy great popularity energy-conservation because of it in recent years, the service time of saving money.LED is photoelectric device, has only 15%～25% electric energy to convert luminous energy in its course of work, and remaining electric energy nearly all converts heat energy to, and the temperature of LED is raise.In great power LED, heat radiation is a big problem.For example, 1 10W white light LEDs is if its photoelectric transformation efficiency is 20%, then there is the electric energy of 8W to convert heat energy to, if do not add cooling measure, then the device core temperature of great power LED can rise rapidly, when its junction temperature (TJ) rises above maximum allowable temperature (generally being 150 ℃), great power LED can damage because of overheated.Therefore in the high-power LED lamp design, topmost design work is exactly a heat dissipation design.The electronic equipment local pyrexia is not got rid of, and causes the electronic devices and components high temperature failure.
The service life of general according to statistics led light source is more than 10 years, and the service life of power supply unit about 2 years, this has caused because of long service life by the led light source that extensively is suitable for because of not being fully used the service life of power supply unit.Be to need the common problem that solves in the global LED industry service life that how to prolong power supply unit.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of LED lamp device with heat sinking function to be provided.
The technical solution adopted in the utility model is: a kind of LED lamp device with heat sinking function, comprise light fixture, described lamp interior upper end is equipped with power supply unit, the power supply unit below is equipped with heat sink, be provided with pcb board below the heat sink, pcb board is connected with led light source by heat-conducting glue, and described light fitting body is provided with the steam vent of hollow out.
As preferably, described steam vent is the circular row pore.
As preferably, the aperture of described steam vent is greater than 0.5mm, and steam vent quantity is more than 2.
The utility model lamp interior is provided with power supply unit, power supply unit can produce a large amount of heats in operation, light fitting body adopts the circular aperture design, the aperture is greater than 0.5mm, quantity is more than 2, the heat of lamp interior can pass to out by the aperture, thereby the aperture design more than 2 makes heat convection current reach better radiating effect.
The utility model scope of application is wide, can extensively be useful for the device that bulb lamp, street lamp, car light etc. are equipped with power supply unit.
Beneficial effect: the utility model is simple in structure, and practical material is industrial common used material, has heat radiation and characteristics such as with low cost.
