Abstract
The utility model discloses a light source device of an LED advertising lamp box. The light source device comprises an aluminum substrate connected to a radiator; an LED lamp bead is arranged on the aluminum substrate; a lens is arranged above the LED lamp bead and fixed on the aluminum substrate; the lens comprises a light condensing area and a light diffusing area; and the aluminum substrate, the LED lamp bead and the lens are fixed on the radiator in a wrapped manner through PVC glue. Through the combination of the light condensing area and the light diffusing area, the lens can diffuse brighter light in the middle of the LED and condense the peripheral scattered light, so that the distant light and nearby light of the lamp box are basically the same and the lighting effect of the whole lamp box can be achieved with only one light source arranged for one square meter or larger areas. The use and the special design of the radiator guarantee long service life and high light output of the LED.
Description
Technical field
The utility model LED lighting field, particularly relates to a kind of light supply apparatus of LED advertising lamp box.
Background technology
The field of throwing light at advertising lamp box at present, the light source adopting is exactly mainly fluorescent tube and two kinds of basic schemes of LED module, the general every square metre of need of fluorescent tube are arranged 4, and adopt the scheme of LED module to be generally divided into two kinds of arrangement modes, one is straight-down negative, one is side entering type, what employing straight-down negative was Illuminative for sign is the most common, module used is more, up-to-date technology, can accomplish that every square metre only needs 30 several modules, this is almost the limit of current technology, its main design is, adopt the LED of 1-3W to make light source, then on LED, fill one and expand optical lens, light is launched, thereby the quantity of module is tailed off, another kind is exactly side entering type, first this scheme is to have adopted to clear off lens, make its light sending be strip, only module need be installed in use to the both sides of lamp box, the complementary air exercise of light that allows both sides, is utilized its light fully, thereby realize the effect that just can illuminate whole lamp box with less module, but still needing 20 several LED modules, the quality of more its thermal diffusivities of LED module just determines the length in its service life, so existing LED module need to have good heat dispersion.
Utility model content
For above-mentioned the deficiencies in the prior art part, the utility model provides a kind of as long as light source just to can solve the light supply apparatus of the LED advertising lamp box of the problem that above-mentioned prior art exists.
To achieve these goals, the technical solution adopted in the utility model is: a kind of light supply apparatus of LED advertising lamp box, comprise the aluminium base being connected on radiator, described aluminium base is provided with LED lamp pearl, LED lamp pearl top is provided with the lens that are fixed on aluminium base, and described lens comprise He Kuoguang district, extraction regions; Described aluminium base, LED lamp pearl, lens are coated and fixed on radiator by PVC sizing material.
Further, described lens surrounding edge is divided into extraction regions, described lens mid portion Wei Kuoguang district, and lens bottom is provided with two locating dowels that snap onto above on aluminium base.
Further, described aluminium base is provided with the spacing hole of fixed lens, and described locating dowel is connected in spacing hole.
Further, described radiator is provided with the draw-in groove of fixing aluminium base.
Further, the LED lamp pearl, aluminium base, lens, the radiator integral that described in, connect are coated by PVC sizing material high-pressure injection moulding.
Further, the LED lamp pearl, aluminium base, the lens that described in, connect are coated in described radiator by PVC sizing material high-pressure injection moulding.
Further, described radiator outer surface is provided with the bar of some projections.
Compared with prior art, the beneficial effect of this utility model: lens of the present utility model are divided into two parts by Kuo Guang district and extraction regions light, the light that LED sends at middle part is by the diffusion of Kuo Guang district break-in; The astigmatism that LED sends at edge can slightly be gathered light and launch in the extraction regions of outer edge part by scioptics, and zero angle, boundary that light can form total reflection by extraction regions is 42 degree left and right.The lens of this device can make light-struck farther, thereby realize lamp box light at a distance and wide causing quite nearby, thereby can realize one square metre with regard to a light source, even larger area just adopts our light source just can realize the illuminating effect of whole lamp box.Be provided with four protruding cylinders at the lower surface of lens in addition, it can be located more accurately in fastening lamp pearl, lamp pearl is positioned to the center of lens.
Adopt radiator, the distribute bars of a lot of projections of the outer surface of radiator, to increase and the contact area of air, increase the convection current between air, and good radiating effect is played in very fast the distributing of heat that light fixture is produced; Be provided with two circular holes near the two ends of radiator, the installation when being conducive to the location of aluminium base and product and using; Dispel the heat by this scheme, through strict heat analysis, good heat dissipation effect, controls LEDPN junction temperature in 85 degree, thereby really realizes the long-life of LED and high light output.
Brief description of the drawings
Fig. 1 is the utility model front view;
Fig. 2 is the utility model longitdinal cross-section diagram;
Fig. 3 is luminous intensity distribution schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Embodiment: referring to Fig. 1 to Fig. 3, a kind of light supply apparatus of LED advertising lamp box, first the large-power LED light bead of 3-10W of OSRAM or CREE 1 and components and parts are pasted to the front that is welded in aluminium base 3, aluminium base 3 back sides are welded with the wire 2 electrically connecting with LED lamp pearl 1, again the openend of lens 6 is closely buckled in LED lamp pearl 1 directly over, and two cylinders that make lens 6 snap in two circular holes of aluminium base 3 accurately, to weld again lamp pearl 1, components and parts insert in the draw-in groove of radiator 5 with the aluminium base 3 that installs lens 6, finally by LED lamp pearl 1, lens 6, aluminium base 3, radiator 5 entirety are put into first ready-made tool together, adopt high-pressure injection moulding technique by LED lamp pearl 1 with PVC sizing material 4 again, wire 2, lens 6, aluminium base 3 is injection-moulded in entirety of the interior formation of radiator 5, and be also provided with some projections for dispelling the heat on radiator 5 surfaces.
The He Kuoguang district, extraction regions of the lens 6 in above-described embodiment is one-body molded, scioptics 6 spread light brighter centre, and the light that surrounding is disperseed converges, thereby realize lamp box light at a distance and wide causing quite nearby, thereby realize one square metre with regard to a light source, even larger area adopts a light source just can realize the illuminating effect of whole lamp box, simultaneously the employing of radiator and particular design realized long-life of LED and high light output medial recess can optically focused, surrounding be along can spread light, its luminous intensity distribution schematic diagram as:
The above be the utility model preferred embodiment, it does not form the restriction to the utility model protection domain, all should belong to protection domain of the present utility model as long as what realize the utility model object with essentially identical means.
