Description
[technical field]
The present invention relates to the LED lighting technical field, or rather, relate to a kind of LED lighting device with great heat radiation effect.
[background technology]
In the prior art, as lighting source, begun using with LED, advantage such as have the energy of saving, increase the service life, but the heat dissipation problem of LED is influence the LED key in application of throwing light on.
A large amount of heat that the LED lighting device produces when work, as can not get timely heat radiation, these heats can cause the LED luminosity to reduce, and shorten service life.For example, brightness is 100 when the LED operating temperature is 25 ℃, and temperature when being increased to 75 ℃ brightness just reduce to 80, to 125 ℃ surplus 60, during to 175 ℃ only surplus 40.Operating temperature and luminosity are the relations that is the inverse ratio linearity, and temperature more raises, and it is dark that LED brightness is just more changeed.Temperature is linear to the influence of brightness, but the influence in life-span just is index, uses if remain on below 50 ℃ always, and then LED has nearly 20,000 hours life-span, 75 ℃ then only remain 10,000 hours, and 100 ℃ remain 5,000 hours, 125 ℃ remain 2,000 hours, and 150 ℃ remain 1,000 hour.Temperature light just shortened 1/4 times 5,000 hours service life into from 50 ℃ of 100 ℃ of becoming 2 times from 20,000 hours, influence greatly.Therefore, a kind of appearance of not only having satisfied lighting requirement but also having possessed the LED lighting device of great heat radiation effect is called in market.
[summary of the invention]
The technical problem that the present invention solves is to overcome the defective that prior art exists, and a kind of LED lighting device that possesses great heat radiation effect is provided.
The present invention is achieved by the following technical solutions: a kind of LED lighting device, comprise housing, circuit board and some LED, described LED is installed on the circuit board and is contained in the housing, described circuit board is the metal material circuit board, this circuit board is fixed on the described housing by soft high heat conductance heat-conducting glue, the part that described housing is connected with circuit board by soft high heat conductance heat-conducting glue at least is a metal material, and the metal that is connected with circuit board on described housing part is same metal material with circuit board.
Described soft high heat conductance heat-conducting glue can be a scolding tin.
Described circuit board is the aluminum metal circuit board.
Described LED lighting device can be LED street lamp, LED Projecting Lamp or LED Tunnel Lamp.
Compared with prior art, disclosed LED lighting device is by being fixed on circuit board on the housing through soft high heat conductance heat-conducting glue, and make the metal part that connects with circuit board on the housing identical with the material of circuit board, thereby the heat that produces when making the work of LED lighting device can distribute by housing in time, guarantee that this LED lighting device has better heat radiating effect, and simple in structure, cost is low.
