Description

The LED lamp module

Technical field

The utility model relates to LED illuminating lamp technical field, refers in particular to a kind of LED lamp 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 the different photochromic combinations of 130% full color, 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.

This street lamp of the prior art is in order to reach sealing and water resistance, especially adopt the transparent plastic material lampshade of seal glass or sealing, radiating effect is poor on the one hand to adopt this lampshade, its light transmission is also undesirable on the other hand, the phenomenon that light reflected back light emitting source on lampshade inevitably can occur, effect and effect when therefore not bringing into play LED lamp institute normal operating condition.

The utility model content

The purpose of this utility model is to provide that a kind of light transmission is strong, the LED lamp module of good heat dissipation effect.

For addressing the above problem, LED lamp module of the present utility model, it is characterized in that: the LED lamp plate is divided into some arrangement composite modules, the no cloche pattern of the peripheral realization of LED lamp plate, leave certain clearance between every two adjacent modules, module is fixed on the lamp housing by connector at two ends, and each module all has separately independently lamp socket, panel, radiator, draw-in groove and wiring hole, and the circuit between each module is for being connected in parallel.

LED lamp module of the present utility model also comprises and has a following feature:

Described module is a strip, the draw-in groove at module two ends and waterproof bar and connector snap fit connection mutually.

Compared with prior art, LED lamp module of the present utility model, with LED lamp plate modularization, connect with connector between the module everywhere, large-area strap shape radiator is divided into several small sizes and separate little radiator, leave certain clearance between each adjacent modules, so that cold air rapid fluxion strap is from bottom to top walked the heat on the radiator, thereby the LED junction temperature is controlled in the desirable scope, and this modular structure has very big flexibility, can arbitrarily design the street lamp of different capacity and different-style, to be fit to different occasions, the needs of highway section illumination.

The specific embodiment

Below in conjunction with the drawings and specific embodiments LED lamp module of the present utility model is described further, shown in Fig. 1-4:

LED lamp module of the present utility model, LED lamp plate are divided into eight permutation and combination modules 1, and module 1 comprises independently lamp socket 10, panel 11 and radiator 12.Circuit between each module 1 is for being connected in parallel, like this when fault takes place in one of them module 1, do not influence the operate as normal of other module 1, lamp socket 10 is arranged on the panel 11, panel 11 is fastenedly connected with radiator 12 usefulness screws, radiator 12 is provided with waterproof bar 13 and draw-in groove 14, is equipped with sealing device on lamp socket 10, panel 11 and the radiator 12.

Connector 2 comprises the fixing snap ring 22 of clamp 21 and in an outer card plate 20 and, and connector 2 is distributed in the both sides of lamp housing, and connector 2 is enclosed within by fixing snap ring 22 on the fixed axis 30 of lamp housing 3 and is fixed on the lamp housing 3.

The outer card plate 20 of connector 2 is stuck in waterproof bar 13 outsides of module 1 and is fastened with waterproof bar 13 and cooperates.The interior clamp 21 of connector 2 is buckled on the draw-in groove 14 at two ends up and down, and connector 2 is fixed together by outer card plate 20 and linking closely of interior clamp 21 with module 1.Connector 2 is fixed together with lamp housing 3, so module 1 is fixed together with lamp housing 3.

Module 1 is generally elongate in shape, each module 1 is arranged mutually by connector 2 and is fixed on the lamp housing 3, leave certain clearance between each adjacent modules 1, so that cold air rapid fluxion strap is from bottom to top walked the heat on the radiator, thereby the LED junction temperature is controlled in the desirable scope, and this modular structure has very big flexibility, can arbitrarily design the LED lamp of different capacity and different-style, to be fit to different occasions, the needs of highway section illumination, it has cancelled the glass on the light fixture or other transparent material in the prior art, has not only increased light emission rate but also has effectively alleviated the weight of lamp.

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.
