Description of drawings
Fig. 1 is the structural representation of the LED lamp of the gradable light modulation of the utility model, toning.
The specific embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
As shown in Figure 1; The LED lamp of a kind of gradable light modulation, toning; Comprise pedestal 1, fixed frame 2, power module and at least two separate led circuits; Power module is to be made up of a plurality of independently power supplys 33, each independently power supply 33 supply power separately to the led circuit of corresponding connection respectively with it.Pedestal 1 upper surface is provided with led chip weld zone and the positive second battery lead plate weld zone; The ring-type that is shaped as hollow of fixed frame 2; It is installed on the upper surface of pedestal 1; Thereby expose a part of upper surface of pedestal 1 at the hollow position of fixed frame 2 ring-types, promptly with the upper surface of the corresponding pedestal 1 of fixed frame 2 ring-type hollow positions, the led chip weld zone promptly is arranged on the upper surface of this and the corresponding pedestal 1 of fixed frame 2 ring-type hollow positions; Fixed frame 2 is provided with the first battery lead plate through hole and the second battery lead plate through hole, and zone corresponding with the first battery lead plate through hole, the second battery lead plate through hole on pedestal 1 upper surface is the positive second battery lead plate weld zone.
Each independently led circuit include independently led chip group, one first battery lead plate 31 and one second battery lead plate 32 independently independently; Wherein, Each independently the led chip group be to constitute by a plurality of led chips 34 that mode that combines with series system, parallel way or series and parallel or multiple mode such as intert connect; The led chip bond pads of led circuit with the upper surface of the corresponding pedestal 1 of fixed frame 2 ring-type hollow positions; Promptly be connected the led chip weld zone of pedestal, the led chip 34 of forming a plurality of led chip groups can be fixed on the led chip weld zone through various arrangement modes, is the arrangement mode of M * N shown in Fig. 1; M >=1 wherein, N >=1.
Each independently the led chip group a pair of independently battery lead plate is all arranged; Wherein, One end of first battery lead plate 31 directly is connected with the led chip group, the other end pass behind the first battery lead plate through hole of insulation on the fixed frame 2 can with 33 anodal connections of power supply independently, an end of second battery lead plate 32 is connected with the led chip group; The other end pass the insulation fixed frame 2 the second battery lead plate through hole after can with one independently power supply 33 negative poles be connected; Each independently power supply 33 be independently led chip group power supply through a pair of independently battery lead plate, through each independently the control of power supply 33 break-makes control the switch of led chip group in each road, thereby realize the switch of LED multi-path circuit; Realization is to the incremental dimming of LED lamp; Progression is that the way of supposing the LED independent circuits is n (n >=1), so just can realize the light modulation of n+1 level by the decision of the number of independent led circuit.Simultaneously; Each led chip group can be selected the led chip of different colours; The glow color of led chip can be from ultraviolet to infrared; Realize the luminous of different colours, various led chip specifications all are suitable for, and are preferably the general auspicious BXCE4545457-E1-B chip of the ES-CADB/BLV24H chip and the U.S. of the brilliant unit in Taiwan in the present embodiment.Through controlling each independently switch of power supply 33, control the break-make of each led circuit, can realize the incremental dimming of LED lamp.
Form angle between the upper surface of the inwall of fixed frame 2 and pedestal 1, the angle angle can be regulated in 90 ~ 150 ° of scopes.The inwall of fixed frame 2 and be coated with one deck reflector layer 4 with the upper surface of the corresponding pedestal 1 of fixed frame 2 ring-type hollow positions; The high anti-layer of this reflector layer 4 for realizing through modes such as silver-plated or polishings; Its effect is that the light to the side and the back side that makes led chip 34 sent is reflected into positive reflection, thereby improves the light extraction efficiency of led chip group.
Independently the electric current of power supply 33 according to the series and parallel mode of the size of led chip group and led chip 34 can range of choice in 0 ~ 10A; Voltage can be chosen as in 0 ~ 400V scope according to the quantity of led chip 34; And power supply 33 can have the function of regulating size of current, and the light and shade of controlling the LED lamp through the size of regulating electric current changes.
Pedestal 1 is a cooling base; It is by like high heat conductive metal such as copper, aluminium, iron, silver; It also can be pottery; Various highly heat-conductive materials such as graphite, diamond, heat pipe and structure are processed, and its shape can be square, circular, rectangle, rhombus and various irregular shape, decides according to different application scenarios.The shape of fixed frame 2 confirms according to the shape of pedestal 1, can be square, circular, rectangle, rhombus and various irregular shape, and its material can be insulating materials such as PPA plastic cement, resin or various polyamides plastics, and 150 ℃ of high temperature of ability.
Power module in the LED lamp of the gradable light modulation of the utility model, toning can also have the multichannel output pin for a power module; Each output pin connects a led circuit; Thereby control the break-make of each led circuit through the switch of every road power supply output, thereby realize incremental dimming, the toning of LED lamp.
The LED lamp of the gradable light modulation of the utility model, toning has not only improved LED lamp installation and application flexibility greatly, and the corresponding circuit independently of each led chip group, and each road is all independently-powered by the multichannel output of independent power supply or same power supply; Directly through controlling the perhaps break-make realization incremental dimming of the power supply on a few roads of a certain road, progression is by the number decision of independent circuits, simultaneously; Can also need not add under the situation of fluorescent material, the color through changing each road or the combination of LED modules with different colors chipset realize the luminous of different colours; Or mixed luminescence, obtaining the optical effect of different-colour, this just significantly reduces a series of problems that fluorescent material brought of using; Simplified technology, reduced cost, at beam projecting in airborne process; Every increase one deck medium will increase the absorbed layer of one deck to light, because led chip encapsulation is with fluorescent material and the epoxy resin absorption to light; And in the process of excitated fluorescent powder, luminous energy also can lose, and so at first is unfavorable for the utilization of luminous energy; Simultaneously; The too much heat energy that changes into also has adverse influence to the performance of device, and adopts this structure can realize need not adding the light that fluorescent material just can obtain different colours, the problem of having avoided the efficient that fluorescent material brought to reduce effectively.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
