The underwater LED lamp has excellent heat dissipation performance and waterproof performance, and meanwhile, the high-power LED lamp bulbs have higher brightness, so that the underwater LED lamp is suitable for being used under the water for a long time.

Description

A kind of lamp of LED under water

Technical field

The utility model relates to the LED lamp, especially a kind of lamp of LED under water.

Background technology

Along with increasing of various ponds class, underwater lighting needs constantly development to satisfy needs of people.The majority of lamp under water of prior art all is the life waterproof construction that sealing ring is set, and water resistance and heat conduction are undesirable, and the light fixture of working under water for a long time for needs can't fully guarantee its operate as normal.Owing to visibility in the water is lower, need powerful light source could satisfy the needs of illumination simultaneously.Traditional incandescent lamp has shortcomings such as power consumption is big, heating is many, the life-span is short, volume is big as light source, and the cost of changing, using is high, general LED lamp pearl good energy-conserving effect, but brightness is not enough.

The utility model content

In order to solve the deficiency of prior art, the utility model discloses a kind of lamp of LED under water, and this LED light fixture has excellent waterproof and radiator structure and high brightness characteristics, is particularly suitable for using under water.

The utility model for the technical scheme that solves its technical problem and adopt is: a kind of lamp of LED under water; Comprise LED lamp pearl, driving power, substrate, radiator, housing, clamshell; The bead weld of said LED lamp is connected on the substrate, and the substrate lower end connects radiator, and driving power places the radiator middle part; Radiator is close to housing, is provided with filler the LED lamp pearl from housing bottom to substrate.

Further, said LED lamp pearl is the large-power LED light bead of 1W.

Further, said LED lamp pearl quantity is 18.

Further, said driving driving power is a constant-current source.

Further, said substrate is the PCB aluminium base.

Further, said radiator is the aluminum heronsbill radiator structure of three petals.

Further, said filler is a heat-conducting glue.

Further, the power input line of said driving power is provided with the waterproof ring epoxy resins.

Further, said clamshell is the safety glass cover.

Further, said housing is a Stainless Steel Shell.

The utility model adopts the large-power LED light bead of 18 1w as light source, and underwater brightness is higher, and whole power is below 20W, but but the incandescent lamp with 150W is suitable in brightness, and caloric value is low, rapid heat dissipation, and the life-span is longer, and is more energy-conservation, more environmental protection.In addition, heat-conducting glue all pours into LED lamp housing bottom to the space below the LED lamp pearl lamp holder and fills up, and has so just fully guaranteed the water resistance of LED lamp.Under the condition that brightness and water resistance all are resolved, the utility model can be for a long time operate as normal under water.

The specific embodiment

The utility model is described further through embodiment below in conjunction with accompanying drawing.

The utility model comprises housing 1,radiator 2,substrate 3,LED lamp pearl 4,clamshell 5 and driving power 6.As preferably,LED lamp pearl 4 is the large-power LED light bead of 1w, and quantity is 18.Housing 1 is a Stainless Steel Shell, andradiator 2 is the aluminum heronsbill radiator structure of three petals, andclamshell 5 is the safety glass cover, anddriving power 6 is a constant-current source.SaidLED lamp pearl 4 is welded on thesubstrate 3;Substrate 3 times is adjacent toradiator 2 with heat conduction;Driving power 6 is located at the middle part ofradiator 2, andradiator 2 is adjacent to housing 1 again, arrives the space between theLED lamp pearl 4 with heat-conducting glue perfusion housing 1 bottom;Flood substrate 3 up to heat-conducting glue, but will expose large-power LED light bead.Then, seal the power input line place, install the installation of just having accomplished the whole lamp of LED under water to clamshell 5 again with the waterproof ring epoxy resins.

The describedsubstrate 3 of the utility model is the PCB aluminium base, and filler is a heat-conducting glue, and two kinds of structures all help the LED heat radiation, and Stainless Steel Shell more helps quick heat radiating than plastic casing simultaneously.Because heat-conducting glue is all filled LED lamp welding foot and covered, and only exposes LED lamp pearl pearl shell, and the power input line place also seals with the waterproof ring epoxy resins, so the LED light fixture of the utility model has extraordinary water resistance.In addition, the light source that the large-power LED light bead of 18 1w is formed, the lamp source that brightness ratio is general is higher.So, the utlity model has the advantage of good water resistance, heat dispersion and high brightness, work long hours at the bottom of being highly suitable for the pond.
