Technical field
The utility model belongs to a kind of LED shot-light in the semiconductor lighting equipment technical field.
Background technology
Along with growing and scientific and technical the advancing by leaps and bounds of illuminating equipment, also more and more higher to the shot-light specification requirement of lighting installation.Especially LED (being light emitting diode) light source has brought unprecedented opportunity to develop to shot-light again in the application of lighting field.In known technology, existing shot-light is mainly high-pressure mercury lamp, used power is big, power consumption is high, life-span is short, especially with it the big investment of supporting shot-light power supply cable sectional area is high, in today of energy scarcity, is necessary very much to develop as early as possible and adopts white LED light source shot-light energy-conservation, efficient, environmental protection.What but the LED shot-light was required at present mainly is to be formed by connecting with several small-power chip portfolios than high-power LED light source, particularly led light source is a kind of cold light source, limit by its structure, the main luminescence chip of led light source can produce very high work heat energy at work, as the work heat energy of led light source can not being excreted, led chip will lose efficacy in high temperature gradually, thereby the poor radiation problem of high-power LED light source lamp has caused service life short, and the feasible divergence of beam that penetrates of bigger cooling surface area, optical efficiency is low, also have heavier glare problem, these have become the technical problem that high-power LED light source need be captured.
Summary of the invention
In order to overcome the deficiency of prior art, the existing led light source shot-light poor radiation of solution, the problem that optical efficiency is low, the purpose of the utility model provides a kind of novel structure, and design innovation can overcome dazzle effectively, improve luminous efficiency, have energy-saving high-efficiency environment-friendly, luminous soft, thermal diffusivity is good, long service life, and supporting with it shot-light power supply cable sectional area reduces to invest low new-type led light source shot-light greatly.
The technical scheme in the invention for solving the above technical problem is:
A kind of novel white-light LED area source shot-light, it connects the shot-light main body that the lampshade that studs with transparent implosion guard is formed by shot-light pedestal lid, in the inner cavity of shot-light pedestal, be equiped with 1 to several piece (preferably 1 to 8) white light LED area lighting source module, periphery around white light LED area lighting source module is fitted with reflector, the collar extension of reflector is along the bead that corresponds to the transparent implosion guard of lampshade, connect the aluminium radiator that is shaped on several pieces conjuncted radiating fins at the back side of white light LED area lighting source module (being the substrate bottom surface of LED modular surface light source wiring board), radiator is connected in the shot-light pedestal, the electric wire of white light LED area lighting source module connects the power-supply controller of electric that is installed in shot-light pedestal inner cavity, and the external cord of power-supply controller of electric connects power switch and external power supply fully.
Above-mentioned novel white-light LED area source shot-light, the luminous plaque face that the several piece white light LED area lighting source module of load is formed in the described shot-light pedestal chamber is that a plane is provided with, or become the convex surface setting according to LED area source guiding property light-emitting area, comprise frustum of a pyramid shape convex surface, ball arcuation convex surface, circular-arc convex surface, ellipsoid shape convex surface, and the convex surface of other suitable shapes, to enlarge illumination range.
Above-mentioned novel white-light LED area source shot-light, described white light LED area lighting source module is that every white light LED area lighting source module is installed in the reflector lamp bowl, the bucket-shaped lamp bowl in the profile side of being of lamp bowl corresponding matching white light LED area lighting source module, tubaeform lamp bowl, and other and the corresponding suitable type lamp bowl of white light LED area lighting source module, again the lamp bowl periphery load reflector of white light LED area lighting source module is being housed.
Above-mentioned novel white-light LED area source shot-light, described reflector reflector is the bowl-shape reflector of port footpath lamp little, that other end bore is big, the bucket-shaped reflector in the luminous plaque face side of being made for, the horn-like reflector that can form according to white light LED area lighting source module, and other suitable shape reflector.
Above-mentioned novel white-light LED area source shot-light, described power-supply controller of electric are the constant voltage dc source device that alternating current becomes direct-current transformer, or the constant current regulated power supply device, or the Switching Power Supply device provides stable voltage and current for white light LED area lighting source module.
Above-mentioned novel white-light LED area source shot-light, the radiating fin of described radiator are several bar plates arranged side by side or the plate that becomes grid; Also can on the heat radiation wing, be shaped on the heat radiation teeth groove again and improve cooling surface area, the working junction temperature of white light LED area lighting source module can be derived fast and distribute.Radiator edge is connected in the whole outer shot-light main body outside that is exposed on the shot-light pedestal, radiator or being connected in shot-light pedestal inboard is arranged in shot-light main body inner chamber, and corresponding radiator is opened several louvres of system on the shot-light pedestal.
When the utility model used, according to the design needs, load was connected power supply with the external cord connection gauge tap and the power line of power-supply controller of electric on default shot-light bar or lamp socket, can throw light on.Because the white light LED area lighting source module that the utility model adopted is that many particles low-power LED chip is disperseed to distribute in the circuit board, and overall package forms high-power LED surface light source together, make thermal source disperse to distribute, and can heat be passed to the entire radiator that fuses with wiring board by the wiring board substrate fast, dispel the heat by area of dissipation than big hundreds of times of led chip area, make the temperature in the lamp body remain at the normal temperature constant state below 50 ℃ that uses of led chip, long-time use can not cause brightness decay and dead lamp failure, the service life of having improved the LED shot-light greatly.Be that white light LED area lighting source module of the present utility model is to adopt white colloid as crystal-bonding adhesive again, in the cavity of wiring board and frame formation, be filled with transparent adhesive tape, and outside transparent adhesive tape, evenly be packaged with the fluorescent material glue-line, make light source unit are luminous flux be generally less than the 51m/ square centimeter, reflector and transparent glass cover are housed in addition, therefore can overcome dazzle.
Because technique scheme has been adopted in the utility model design, existing led light source shot-light poor radiation, problem that optical efficiency is low have been solved effectively.Show through testing result on trial for several times, show through testing result on trial for several times, it compared with prior art, has novel structure, design innovation, can overcome dazzle effectively, improve luminous efficiency, and supporting with it road lamp power supply cable cross-section long-pending reduce greatly to invest low, and has an energy-saving high-efficiency environment-friendly, luminous soft, thermal diffusivity is good, long service life, working stability, advantage such as easy to install is applicable to various squares, advertisement exhibition board, building, garden, park, plant area etc., has broad application prospects.
