Abstract
The utility model discloses a large-power LED (light emitting diode) luminaire structure comprising a circuit module, an LED light bead and a radiator; the LED light bead is a multi-crystal plane light source adopting a COB (chip on board) package structure; and the radiator is annular and tubular, and is provided with radiating rib sheets at the periphery, inner films which can vibrate by magnetic energy are arranged among the radiating ribs, the light bead is arranged on the surface in the middle part, and a direct current magnetic energy conversion device is arranged on the upper part of the light bead. According to the scheme of the large-power LED luminaire structure, the mutual match of a light source adopting multi-crystal plane light and COB technology and the micro-spray radiator is applied, so that the problem of overlarge volume due to the radiating of the LED application is effectively solved, and the whole volume of the light is one thirds of a conventional light, in addition, the single multi-crystal plane light source is adopted, the spotlighting effect is excellent, the problem of a double image of a radiated object is avoided, the light loss is less, and the mutual light loss of multiple single crystals is avoided.
Description
Technical field
The utility model relates to the LED lighting field, specifically is the LED fitting structure of high-power small size.
Background technology
Along with the LED industry technology is brought in constant renewal in, in the middle of the LED application of coming into people slowly, great power LED such as street lamp, Landscape Lamp etc.The practical application bottleneck of such LED is except price at present, and also having very important factor is the problem of heat radiation and volume; Because of the characteristics of LED are in the spectra collection, except that visible light energy, all other becomes heat (present light efficiency, general about 80% is heat); And conventional light source has more infrared/uv energy, and heating is few.So, adopt LED as light source, dispelling the heat is main putting the axe in the helve, particularly on high-powered LED lamp, so high more at the light fixture volume requirement, contradiction is just more outstanding.
The utility model content
To the problems referred to above, the utility model aims to provide a kind of high-powered LED lamp of small size according to structure, has good thermal diffusivity.
For realizing this technical purpose, the scheme of the utility model is: a kind of high-power LED lamp structure, comprise circuit module and LED lamp pearl, and between said circuit module and LED lamp pearl, also be provided with a radiator; Said LED lamp pearl is for adopting the polycrystalline area source of COB encapsulating structure; Said radiator is the annulus tubbiness, is radiated rib all around, and being provided with between fin can be through the inner membrance of magnetic energy vibration, middle part surface installing lamp pearl, and direct current magnetic energy reforming unit is equipped with on lamp pearl top.
As preferably, said light fixture also comprises reflector, and its rising angle is 90 ℃, through the removable lower end that is fixed on radiator of pull bar is installed.
This programme should effectively solve LED and use because of heat radiation causes the excessive problem of volume with through adopting cooperatively interacting of the technological light source of polycrystalline face light and COB and little spray radiator, whole lamp body is amassed be 1/3 of routine; And, adopting single polycrystalline area source, spotlight effect is splendid, avoids according to thing ghost image problem; Light loss is few, avoids many of monocrystalline to bring mutual light loss.
Description of drawings
Fig. 1 is the structural principle sketch map of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is explained further details.
As shown in Figure 1, a kind of high-power LED lamp structure of the utility model specific embodiment, it comprises circuit module 1 and LED lamp pearl 3, between said circuit module 1 and LED lamp pearl 3, also is provided with a radiator 2; Said LED lamp pearl 3 is for adopting the polycrystalline area source of COB encapsulating structure; Said radiator 2 is the annulus tubbiness, is radiated rib all around, and being provided with between fin can be through the inner membrance of magnetic energy vibration, middle part surface installing lamp pearl, and direct current magnetic energy reforming unit is equipped with on lamp pearl top.Said light fixture also comprises reflector 4, and its rising angle is 90 ℃, through the pull bar 5 removable lower ends that are fixed on radiator are installed.
Existing with regard to an optimum implementation; Explain as follows: adopt with the celebrated CITICEN 26W LED of single high-power area source; Through the OVERDRIVER mode,, succeed in doing 35W in conjunction with the air-cooled technological radiator of the little spray of NUVENTIX; And be made in overall plan in the very little space of volume, the volume of whole lamp scheme is 1/3 of a conventional scheme.
The scheme application parameter:
The lamp source: CITIZEN CL-L3303000K/5000K, CITICEN CL-L330 light source is the polycrystalline area source, unique COB encapsulation, ultralow thermal resistance (2.4 ℃/W), superelevation junction temperature (150 ℃) is for good heat radiation provides essential condition; Add single polycrystalline again, (25.75X19mm) is little for area, and more little spatial design provides application foundation; Cooperate cooling system, (make single light source output power reach 35W through OVER DRIVER.The colour rendering that adds CITICENR is high, and colour temperature/look floats characteristics such as scope is little, and the life-span is long, and to be that scheme provides perfectly supporting.
Radiator: this radiator of NUVENTIX PAR38; The micro-spray technology that adopts the electromagnetism wind energy to change each other; 35w heat radiation cumulative volume is 1/3. its principle of the aluminium radiator volume of general nature convection current: the heat radiation kernel feeds direct current, through DC converting, converts electric energy to magnetic energy; Promote inner membrance generation microvibration through magnetic energy then and produce wind, utilize air-cooled principle to dispel the heat.Though have suffered journey is the magnetic energy vibration, and vibration is microvibration, and noise is very little, and people's ear home is difficult to hear.
Power output: 35W (LED OVER DRIVER)
Whole light is imitated: 2300LM (3000K) 3500LM (5000K)
Colour rendering index: 85 (3000K)/70 (5000K)
Applied environment temperature :-30 ℃~50 ℃
Whole lamp body is long-pending: 155 (H comprises power supply) of 220mm (∮) X; The diameter of heat radiation is 95mm, height 46mm
Life-span: 50000H
Light source luminescent angle: 120 ℃
This preferred plan cooperatively interacts through CITIZEN light source and radiator, effectively solves LED and uses because of heat radiation causes the excessive problem of volume, and the relevant feature of this application is mainly following:
1, volume is little.Adopt the CITIZEN light source of polycrystalline face light and COB technology, the low junction temperature of thermal resistance is high, can effectively solve the excessive problem of many volumes of monocrystalline; Scheme adopts the little spray radiator of NUVENTIX simultaneously, and real is that the whole lamp scheme volume of minimizing is made something perfect even more perfect, and making whole lamp body long-pending is 1/3 of routine.
2, power is big.Adopt CITIZEN CL-L33026W light source,, make the light source real output reach 35W (CITIZEN producer is through long-time aging safety verification) through Over driver mode.
3, light efficiency is high.Adopt the scheme of 3000K color temperature light sources, can reach 2300LM through actual measurement light efficiency value; And adopt colour temperature 5000K light source, and light efficiency can reach 3500LM, single polycrystalline area source, and spotlight effect is splendid, avoids according to thing ghost image problem; Light loss is few, avoids many of monocrystalline to bring mutual light loss.
The above; Be merely the preferred embodiment of the utility model; Not in order to restriction the utility model, every technical spirit according to the utility model to any trickle modification that above embodiment did, be equal to replacement and improve, all should be included within the protection domain of the utility model technical scheme.
