Description

Thin-type LED lamp structure

Technical field

The present invention relates to a kind of LED modulated structure, refer in particular to and a kind ofly have waterproof, shockproof, the impact of preventing dust, prevent the power supply instantaneous variation concurrently, improve illumination zone and illumination usefulness, promote heat dissipation and be slim LED modulated structure, and be applicable to the goods lamp (cargolight) of various container car (for example refrigerated enclosed container car), also be applicable to various illuminating lamp such as throw light in night illumination, Landscape Lighting, the water.

Background technology

Be used in the goods lamp of various container car (for example refrigerated enclosed container car) in the past, owing to use fluorescent lamp or incandescent lamp, cause that power consumption is arranged, be difficult at low temperatures light a lamp and cause the life-span of lamp obviously to shorten, irradiation light contains the harmful infrared ray of goods or ultraviolet ray and volume bigger than normally and be unfavorable for putting or stacked cargo disappearances such as (because goods Hui Touch bump against the goods lamp), thereby has the dealer to change with LED as light emitting source.

But, use the existing goods lamp of LED as light emitting source, but still also have following disappearance to remain to be improved:

When (1) container car carries out in the cabinet cleaning operation, generally clean with injection water, the waterproofing design of only existing goods lamp also can't be born injection water, causes infiltration in the goods lamp and fault; Be example with the refrigerated enclosed container car again, in carrying out cabinet during cleaning operation, also further use about high steam or hot water more than 80 ℃ to clean sterilization simultaneously, the waterproofing design of only existing goods lamp is not good, at expanded by heating and meet between the cold contraction, overall structure will cause because of distortion also being easy to seep water and because infiltration and the situation of fault.

(2) container car will inevitably constantly shake when loading is advanced, and the shockproof function of existing goods lamp but is unable to cope with these shock conditions, causes existing goods lantern festival that the disappearance of day by day damaging is arranged because of these vibrations.

(3) owing to all use the sign LED of low-light (level), although used these about 20～40 LED simultaneously, precisely because the illumination zone and the still wretched insufficiency of usefulness that throws light on, also let alone using so many LED, to cause the overall volume of light fixture excessive, can't meet compact requirement.

(4) if improve to use the illumination usefulness not enough problem of LED as the existing goods lamp of light emitting source, and change the words of using high-brightness LED into, to produce another problem on the contrary: the high heat of high-brightness LED must be in addition heat abstractor by a large volume dispel the heat, can't meet compact requirement and have, for this reason, this case inventor also must design and a kind ofly can improve heat dissipation and the little heat dissipation design of volume.

(5), result in and also reduce its illumination usefulness because the irradiation of the light of existing goods lamp is also inhomogeneous.

(6) the existing employed LED of goods lamp is white light LEDs, be example only with the refrigerated enclosed container car, when opening the cabinet door, because hot and cold interactive relation, result in the white fog that generation is filled the air everywhere, the white light that white light LEDs sent will allow the people can't see clearly Chu because of the influence of white fog, influences the carrying of goods.

(7) a plurality of attached power devices must be arranged on the car, the variation in voltage of these attached power devices when repeating ON/OFF is bigger than normal, with the refrigerated enclosed container car is example, that is disposed on it beats surge voltage or the electric current that attached power devices such as refrigerant motor are taken place when ON/OFF, to produce excessive variation in voltage, cause in the car employed goods lamp to be subjected to the impact of these variations in voltage and damage, fault.

(8) because existing goods lamp rationalizes in order to make cost, therefore be not designed to: can corresponding temperature change, the structure of shockproof and shock-resistant (impact that anti-power supply instantaneous variation is produced).

Summary of the invention

One of purpose of the present invention, be to provide a kind of thin-type LED lamp structure, by between the joint of lid, pedestal, heat sink and light-guiding shade, respectively being provided with at least one mine dam (for constituting) by the concave, convex designing institute, thereby has preferable waterproof performance, decapacitation is born outside the injection water, can also avoid being out of shape because touch high steam or hot water troubling seepage problem, in the thin-type LED lamp, also be filled with packing material and have waterproof and dustproof and shockproof effect concurrently; Again by using high-brightness LED to allow the usage quantity of LED significantly reduce, correspondingly allow the LED lamp volume-diminished and can meet compact requirement, the high heat of high-brightness LED then utilizes a heat sink with convection current chamber to reach, the convection current chamber can produce thermal convection current and promote the heat dissipation of heat sink, so this heat sink can be slim and meets compact requirement.

Two of purpose of the present invention; be to provide a kind of thin-type LED lamp structure; by at least one holding circuit with constant-current circuit is set at circuit board; and this constant-current circuit control direct current becomes non-polar direct current, thus have the effect of holding circuit and when plug-in, have will not wrong plug polarity effect.

Three of purpose of the present invention is to provide a kind of thin-type LED lamp structure, by further set up a waterproof bar between light-guiding shade and lid, promotes its waterproof performance thereby also add.
