Description

A kind of LED lamp with double-radiation function function
Technical field
The utility model relates to a kind of LED lamp, particularly relates to a kind of LED lamp with double-radiation function function.
Background technology
High-pressure mercury lamp is mostly adopted in traditional road lighting, but the development along with science and technology, the LED lamp relies on luminous efficiency high, low power consumption, do not need high pressure, the advantages such as security height, be widely used at various lighting fields, but when being some large area illuminations (such as headlight, street lamp, Tunnel Lamp, plaza lighting, industrial light, garden lamp etc.), at this moment the power of LED lamp is larger, the life-span of led light source and the operating temperature of node have closer contacting, at present the LED lamp only has 15%~25% electric energy to convert luminous energy in the course of the work, remaining electric energy nearly all changes into heat energy, the temperature of LED lamp is raise, and every increase by 10 its reliabilities of degree of temperature will reduce half.In great power LED, heat radiation is a large problem especially.Bad meeting directly causes the LED quick aging if dispel the heat, and stability reduces, bad can the generation life-span that serious light decay affects lamp of dispelling the heat simultaneously.
The utility model content
The problem relatively poor in order to solve in the prior art LED lamp radiating effect, that service life is short, the utility model provides a kind of good heat dissipation effect, the safe and reliable LED lamp with double-radiation function function.
In order to address the above problem, technical solution adopted in the utility model is:
A kind of LED lamp with double-radiation function function, comprise cooling base, circuit board and led array light source, it is characterized in that: also comprise the fluorescence cover, temperature-uniforming plate, some heat pipes and some radiating fins, be provided with temperature-uniforming plate at cooling base, be provided with circuit board at temperature-uniforming plate, at circuit board three led array light sources are installed, be packaged with transparent silica gel at the led array light source, be equipped be used to the fluorescence cover that covers the led array light source at the cooling base top, base at cooling base is provided with some row's radiating fins, leave the space between adjacent two radiating fins, be provided with some transverse concave grooves in the temperature-uniforming plate bottom, one end of heat pipe is installed in the described transverse concave groove, and the other end of described heat pipe passes cooling base and inserts in some row's radiating fins.
Aforesaid a kind of LED lamp with double-radiation function function is characterized in that: offer some louvres at the fluorescence cover.
Aforesaid a kind of LED lamp with double-radiation function function is characterized in that: described each led array light source is comprised of 9 led chips.
Aforesaid a kind of LED lamp with double-radiation function function is characterized in that: described some row's radiating fins form square radiating fin group.
The beneficial effects of the utility model are:
1, the utility model use temperature-uniforming plate this light, thin, average temperature performance is good, pass to the passive heat radiation element that heat energy speed is exceedingly fast dispels the heat as the first order, can within the extremely short time, conduct heat energy a large amount of on the circuit board, having avoided heat energy to be gathered in affects light quality and service life on the circuit board, the service life of whole LED lamp is longer.
2, be provided with some transverse concave grooves in the temperature-uniforming plate bottom simultaneously, an end of heat pipe is installed in the transverse concave groove, the other end of heat pipe passes cooling base, utilizes at last heat pipe and radiating fin to dispel the heat as two utmost points.Pass through like this double-radiation function, the heat that distributes in the time of great power LED can being worked is transmitted to heat pipe effectively, heat pipe relies on its extremely strong heat-transfer capability that the heat high efficiency of transmission is arrived radiating fin, dissipation of heat is gone out in heat exchange by radiating fin and air, has had efficient heat loss through conduction ability.
