Description

A kind of LED module

Technical field

The utility model is related to field of LED illumination, and in particular to a kind of LED module.

Background technology

LED (light emitting diode) light sources are since it is high with luminous efficiency, power consumption is low, anti-seismic performance is strong, service life The features such as long, environmentally friendly, is known as lighting source and green light source of new generation.Usually LED module is combined to form Lamp bar, the LED module using convex lens optically focused are LED to penetrating module.LED is often applied to advertisement cabinet side to penetrating module, hair The illumination gone out is mapped in the one side for needing advertisement cabinet to be shown, to realize being highlighted for shadow surface.LED module uses the longevity It is closely bound up to order the environment used with it.In a humid environment, if the vapor prolonged stay in air on circuit boards It is just easy to cause the damage of circuit board, so as to cause performance fault.Therefore, in order to ensure LED module composition LED light can Beautiful glittering, the service life is longer, LED information display system should be allowed to avoid humidity as possible.

Conducting wire welding is all made of between LED module on the market at present, is connected between each module after making lamp bar, in lamp bar Outside adds shell, and LED light bar is sealed in closed shell using plug at the both ends of shell.But such place Reason mode is cumbersome for lamp bar of lamp bead when less, and the lamp bar length of less lamp bead is also shorter, and shell is caused to make not side Just, and process is also complex, and the arrangement mode of lamp bar is not also always in one line, can use several row of several rows often Arrangement mode needs wider the aluminum substrate even aluminum substrate of square, so just needs the width direction of entire aluminum substrate It all wraps up, not only needs to use more encapsulating material, but also be also required to larger sized packaging part.However other than leg Aluminum substrate need not generally encapsulate, the aluminum substrate for having leg is all encapsulated not only by traditional packaged type in the width direction The waste for causing encapsulating material, also undoubtedly improves packaging cost.And a large amount of heat can be sent out using LED lamp bead for a long time It is gathered in lens, if these heats pass not in time, is easy for causing the damage of lamp bead.

Therefore it needs to design a kind of LED module, which can also realize good encapsulation when lamp bead is less, no matter How is the width of aluminum substrate, can realize the small range encapsulation of leg, is LED to reduce packaging cost, reduce production cost Module provides a dry environment, and can accelerate the heat dissipation of LED module, extends the service life of LED module.

Utility model content

For the deficiency in the presence of the prior art, the purpose of this utility model is to provide a kind of LED modules, solve The LED module of less lamp bead composition is bothered using shell packaging process at present, and when aluminum substrate is larger is not easy encapsulation and LED lamp bead Radiate slow problem.

To achieve the above object, the utility model uses the following technical solution：A kind of LED module, including aluminum substrate, LED lamp bead and lens identical with the LED lamp bead quantity, the LED lamp bead are fixed on the aluminum substrate, the LED light The both sides of pearl are each to be symmetrical arranged there are one resistance, and the lens cap is set in the LED lamp bead, and the aluminum substrate both sides are symmetrically opened There are mounting groove, the mounting groove to be made of two symmetrically arranged bar-shaped troughs, insulated enclosure is provided between two bar-shaped trough Part, the insulating sealer are installed and used in package conducting wire leg with bar-shaped trough cooperation；The lower section of the aluminum substrate is also set It includes one group of parallel heat sink and the mounting plate perpendicular to the heat sink, the heat sink to have heat radiation rack, the heat radiation rack One end and the aluminum substrate it is integrally formed, the other end is welded and fixed with the mounting plate；One group of the mounting plate it is diagonal on It is equipped with through-hole for fixing；The lens are the truncated cone-shaped cavity body structure of one end open, and the bottom of chamber of the lens is to opening Middle part extends to form round platform, and the bottom of chamber of the lens is the larger bottom surface of the round platform, the inside of the smaller bottom surface of the round platform Be concavely formed the cylinder accommodating chamber for accommodating LED lamp bead to the larger bottom surface of round platform, it is fixed after the LED lamp bead just It is placed in the cylinder accommodating chamber；The light that the LED lamp bead is sent out is through the cylinder accommodating chamber primary event, using institute After the bottom of chamber secondary reflection for stating lens, projected from the bottom of chamber of the lens.

Compared with the prior art, the utility model has the advantages that：

1, it is symmetrically provided with mounting groove in the both sides of the aluminum substrate, each mounting groove is two bar-shaped troughs, between bar-shaped trough Aluminum substrate on after welding lead, can by between two bar-shaped troughs aluminum substrate and conducting wire be encapsulated, the position of bar-shaped trough can It to be arranged according to different situations, is not influenced by aluminum substrate width itself, can realize wider aluminum substrate conducting wire leg Small range encapsulates, and without entire aluminum substrate to be all encapsulated, packaging cost is reduced, to reduce production cost.

2, in aluminum substrate following settings heat radiation rack, the heat of LED lamp bead and resistance can be passed out in time, heat radiation rack Heat sink can by heat derives come；There are gap between mounting plate and aluminum substrate and mounting plate, increased heat transfer Space, it is possible to prevente effectively from the LED module excessively high caused short circuit of heat in use.

3, glue is applied to the opening of lens to realize the fixation of lens and aluminum substrate, LED lamp bead is completely by cylinder Body accommodating chamber covers, and LED lamp bead is not exposed to glue, causes brightness to decline so as to avoid glue stain LED lamp bead.

4, entire LED module can be fixed on LED module by the way of viscose glue, bolt or both and need to use Position at, it is not easily to fall off, the maintenance cost in later stage can be reduced.
