LED lamp waterproof module
Technical field
The utility model relates to LED illuminating lamp technical field, refers in particular to a kind of LED lamp waterproof module.
Background technology
LED Chinese full name is a light emitting diode, a kind of semiconductor that electric energy can be converted into visible light.The LED illumination is the new industry that grows up recent years, the characteristics of LED illumination: the luminous efficiency height, and one two watts LED lamp is equivalent to the illuminating effect of one 15 watts ordinary incandescent lamp bulb; Long service life, LED lamp service life is the longest to reach 100000 hours; LED is a semiconductor element, compares with electronic energy-saving lamp with incandescent lamp, does not have sensing units such as vacuum device and high-voltage triggering circuit, and fault is extremely low, can freedom from repairs; Response time is short, has only for 60 sodium seconds, starts very rapid; Volume is little, in light weight.Utilize its characteristics can design the light fixture of not only thin, not only light but also compact all styles of; LED is bright in luster abundant.It is changeful that color saturation reaches 130% colored different photochromic combination, utilizes sequential control circuit, more can reach colourful dynamic change effect; Harmful substances such as monochromaticjty is good, in the LED spectra collection, does not have spectrum such as unnecessary infrared, ultraviolet, and is not mercurous, heat, radiation seldom belong to typical green illumination light source, and discarded object is recyclable, do not pollute; Single led luminous flux is little.Single led luminous flux research level can reach 120lm/W at present, and the horizontal 75lm/W of industrialized product is flat luminous, high directivity.
As everyone knows, some are used for the high-power LED lamp of street and road and other area illuminations, and the heat that LED produced when lighting all is that the mode that adopts nature to distribute is dispersed into the space with heat usually, and the LED junction temperature is remained on the numerical value.Concrete grammar is earlier LED to be welded on the aluminium base that has circuit and an one deck thin dielectric layer, passes to lamp housing again by aluminium base and heat-conducting silicone grease then, and the fin by the lamp housing outside is dispersed into the space naturally with heat again, thereby reaches radiating effect.But, flange-cooled plate lamp housing is being deposited a lot of defectives, as: according to the requirement of LED heat dissipation characteristics, the power of LED light fixture is big more, the area of dissipation of light fixture is just big more, the reason that rises according to hot-air in addition, the cold and hot air in radiator edge flows easily, and the cold air of radiator core is not easy to obtain to replenish fully, make the convection current fast and effectively of cold and hot air, hindered distributing of core heat, caused the radiator central temperature to be higher than the unbalanced phenomena of lip temperature, thereby caused the LED junction temperature at radiator center to raise, surpassed LED and allow the junction temperature temperature, final LED brightness is decay or damage sharply, makes LED not reach the premium properties of the long service life that was had originally.
Therefore easily adopt the Modular LED lamp plate, easier like this heat radiation and heat radiation evenly prolong the service life of LED lamp, but the water resistance of Modular LED lamp plate is a difficult problem, its waterproof should adopt independently pattern, and promptly each little module all has waterproof sealing measure separately.
The utility model content
The purpose of this utility model is to provide a kind of Modularized LED lamp waterproof module that is used for having on the illuminating lamp water-proof function.
The purpose of this utility model is achieved in that LED lamp waterproof module, comprise radiator, be fixed on the panel on the radiator and be located at lens on the panel lamp hole, radiator and panel are fastenedly connected by screw, radiator is provided with wire hole, it is characterized in that: between lens on the radiator and the lamp hole on the panel, be provided with a lens sealing ring, in wire hole, be with the wire seal circle.
The LED lamp waterproof module of high efficiency and heat radiation of the present utility model also comprises and has a following feature:
Between panel and radiator, be provided with the panel sealing circle.
Compared with prior art, LED lamp waterproof module of the present utility model adopts the separate modular sealing, be independently sealing device on each piece template, the scioptics sealing ring is to the sealing of lens, the sealing of panel sealing circle counter plate and wire seal circle are to the sealing of electric wire, by this sealing of three layers, can guarantee each independently the LED lamp plate have good sealed waterproof effect, outside housing, do not influence its normal use even expose yet.
Description of drawings
Fig. 1 is the structural representation of LED lamp waterproof module of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments LED lamp waterproof module of the present utility model is described further:
As shown in Figure 1, LED lamp waterproof module of the present utility model, comprise radiator 7, be fixed on the panel 2 on the radiator 7 and be located at lens 6 on the lamp hole 8 of panel 2, radiator 7 is fastenedly connected by screw 1 with panel 2, radiator 7 is provided with wire hole 9, be with wire seal circle 4 on wire hole 9, wire seal circle 4 has guaranteed the wire seal of LED lamp plate.Be with a panel sealing ring 3 on panel 2, the profile of panel sealing circle 3 matches with the outline of panel 2, seals by panel sealing circle 3 between panel 2 and the radiator 7.Be covered with a lens sealing ring 5 on lens 6, the upper surface of lens sealing ring 5 tightly is fitted on the panel 2, and is sealed and matched mutually with panel 2, and the substructure of lens sealing ring 5 and lens 6 match.The sealing of 5 pairs of lens 6 of scioptics sealing ring, the sealing of the sealing of panel sealing circle 3 counter plates 2 and 4 pairs of electric wires of wire seal circle, by this sealing of three layers, can guarantee each independently the LED lamp plate have good sealed waterproof effect, outside housing, do not influence its normal use even expose yet.
The foregoing description only is one of preferred embodiment of the present utility model; be not to limit protection domain of the present utility model with this; so: all equivalences of doing according to shape of the present utility model, structure, principle change, and all should be covered by within the protection domain of the present utility model.
