The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figure 1, the LED module based on the high voltage and constant current technology mainly comprises three parts: high-voltage dc stabilization pressuring power, constant flow module and light emitting LED lamp group.Wherein, high-voltage dc stabilization pressuring power adopts the 36V power supply, and in the LED industry, and " high pressure " is the tube voltage drop that the voltage of showing the power supply of LED lamp is higher than LED all the time, and namely all the time greater than 5V, general high pressure is 12V, 24V.By configuration 36V high voltage source, for the consumption that realizes electric energy on remote power-feeding, the saving power transmission line lays the foundation.
Constant flow module is that one in the utility model designs greatly.Because prior art does not adopt constant current technology, therefore be subjected to the influence of voltage attenuation, fluctuation often appears in the electric current on emitting led single lamp, and then the luminosity that causes each emitting led single lamp is difficult to evenly, the uniformity of luminosity then directly affects the aesthetic feeling of outdoor advertising luminescent characters, namely directly affect advertising results, based on this kind problem, the utility model has added constant flow module specially.As shown in Figure 3 and Figure 4, the core of this constant flow module is two LC1912 constant current triodes parallel with one another, colelctor electrode at each LC1912 constant current triode all is connected with a resistance, after the parallel connection of two LC1912 constant current triodes, the high-voltage dc stabilization pressuring power of input and 36V is connected, series connection light emitting LED lamp group behind fast recovery Zener diode SS14 of output series connection.Described LC1912 constant current triode has very high constant current accuracy, can effectively strengthen the antidamping ability of entire circuit, for the light emitting LED lamp group stably provides constant current, guarantees the luminosity unanimity of all emitting led single lamps.
In order to guarantee waterproof and dustproof, anticorrosion ability, the utility model also specialized designs an injection casing, utilize this injection casing, with LC1912 constant current triode, resistance with recover Zener diode SS14 soon and all wrap up as the pcb board of carrier, constant-current circuit extends to the outside of injection casing by lead, realizes being connected with other circuit.In addition, for the ease of the installation of constant flow module, in the injection casing design installing hole is arranged, to realize the installation of constant flow module.
In order to improve overall performance, the utility model has spent great effort in the light emitting LED lamp group, and emitting led single lamp has been carried out major tuneup.As depicted in figs. 1 and 2, in the present embodiment, whole light emitting LED lamp group is formed in parallel by two groups of emitting led single lamps, and in each group, be in series by five emitting led single lamps again, and all emitting led single lamps is identical.The external structure of described emitting led single lamp is made of LED secondary light-distribution lens and an injection casing, wherein, the LED secondary light-distribution lens adopts highly purified transparent PVC material to be made, its light transmittance can reach 98%, and the secondary light-distribution design makes the lighting angle maximum can reach 180 degree, compares with 120 degree of prior art, improve nearly one times, effect is fairly obvious.The bottom of LED secondary light-distribution lens, the position that contacts with injection casing, be designed to can perfect cooperation with injection casing boss structure, as shown in Figure 5, after this position and injection casing connect to one, the LED secondary light-distribution lens had formed complete closed just with injection casing to the inner space, thereby thoroughly solve the waterproof and dustproof problem, guarantee the operate as normal of internal circuit.
As everyone knows, the single lamp of LED is generally long tubular design, therefore, its longitudinal space is enough, if just can seem crowded and the components and parts layout is improper on the horizontal space, even influencing performance and the service life of circuit, the utility model has carried out specialized designs for fear of this problem aspect the layout of internal circuit.At first will arrange along the direction of emitting led single lamp cross section as the pcb board of carrier, then with main luminescence chip---LED3528 is arranged at the upper surface of pcb board, namely towards the direction of LED secondary light-distribution lens, the light source that makes LED3528 send can directly act on the LED secondary light-distribution lens.Also extinguish and extinguish other emitting led single lamps that cause series connection with it for fear of an emitting led single lamp; on LED3528 also individually reverse parallel connection a Zener diode is arranged; because the fast recovery Zener diode SS14 in the constant flow module becomes series relationship with this Zener diode; can prevent reverse Zener diode because circuit connects on the contrary and burns; it is formed the protection effect; therefore; even emitting led single lamp extinguishes; be that LED3528 quits work; can guarantee that also entire circuit still keeps path, to guarantee other emitting led single lamp operate as normal.When the Zener diode in parallel with LED3528 carried out circuit layout, consider the overall structure of emitting led single lamp, this Zener diode is installed on another surface of the pcb board relative with LED3528, namely on the PCB surface of injection casing below.So just make LED3528, pcb board and Zener diode form the vertical arrangement mode consistent with emitting led single lamp shape, the internal structure of emitting led single lamp has been obtained fully, reasonable use.
In the utility model, constant flow module and emitting led single lamp wrap up by injection casing separately, thereby the components and parts that make entire module have all had good dustproof and waterproof effect, and the LED module is strengthened greatly to the adaptive capacity of adverse circumstances, and market value obviously improves.In addition, the connecting line of all circuit is unified to adopt soft imitative silica gel line, and the intermediate connection of positive source, negative pole and circuit is adopted different colors, that is: with positive source link red line, with power cathode link black line, middle connecting line is with white.This design makes that difficulty reduces greatly aspect installation, makes workmen's thinking keep clear, thereby effectively avoids wiring error, guarantees that circuit is normal; Simultaneously, also provide great convenience for the maintenance in the use, maintenance.
By the improvement to above-mentioned each parts, details, the utility model makes outdoor advertising luminescent characters LED module all obtain very big improvement in many aspects such as whole cost, luminescent properties, service lifes, and its market value is had been further upgraded.
Above-described embodiment only is preferred embodiment of the present utility model.In every case do the design of simple transformation on basis of the present utility model, or do not have the change that creative work obtains, all should belong within the protection domain of the present utility model.
