Abstract
The utility model relates to light-emitting device technological field, in particular to an LED indicating lamp using direct current voltage, including several LED luminotron mounted on a circuit board, a shell, a chimney on upper extreme of the shell, a lower head on the lower extreme surface of the shell, and connecting terminals or binding posts on the lower head. The LED luminotron is switched on a direct current voltage ranged from 5V to 24V via the connecting terminals or binding posts, after connecting with resistance in series. The utility model with the advantages of high brightness, wide visual angle, polychromatic light, long service life, saving energy, and convenient fix, could directly switch on an external direct current supply; could be used in different kinds of electrical equipment, and in displaying of information or state of instrument; could directly replace different kinds of direct current indicating lamps with voltage from 5V to 24V; also could be spliced to form integrant photo-arrays, signs, or letters.
Description
Technical field:
The utility model relates to the light-emitting device technical field, refers in particular to a kind of LED light of using DC voltage.
Background technology:
Existing direct current indicator lamp generally adopts ordinary lamps or single LED luminous tube, and ordinary lamps exists the power consumption height, produces shortcomings such as heat is big, the life-span is short.And self can only emit white light, it is colored photochromic impure that the lens filtering by colour obtains.Single LED luminous tube then exists low, the difficult installation of brightness, needs shortcomings such as outer meeting resistance could use.
Summary of the invention:
The purpose of this utility model just is to provide a kind of LED direct current indicator lamp, and it has, and brightness height, visual angle are wide, polychromatic light, life-span are long, energy-conservation, simple in structure, easy to use, direct external direct current power supply characteristics.
For achieving the above object, the utility model comprises a plurality of lampshades that are arranged on LED luminous tube, the housing on the circuit board and are contained in the housing upper end, the lower end of housing is provided with bottom, bottom is provided with binding post or binding post, connects the DC voltage of 5V～24V after the LED luminous tube is connected with resistance by binding post or binding post.
As to further improvement in the technical proposal, housing of the present utility model and lampshade are for being threaded, and the middle part of housing also is provided with a retaining ring, and this retaining ring and housing are also for being threaded;
As the further improvement again to technique scheme, the lateral wall of bottom is fastened on the inner face of housing;
When technique scheme was done further improvement again, the surface of lampshade can be an arcwall face.
After adopting technique scheme because LED direct current indicator lamp has adopted a plurality of LED luminous tubes, brightness near or surpass ordinary lamps, be several times of single LED luminous tube, and energy-conservation, the life-span is long.
The LED luminous tube back of connecting with resistance connects the DC voltage of 5V～24V by binding post or binding post, uses conveniently, can directly substitute the various DC voltage indicator lamps that have 5V～24V now.
And housing and lampshade adopt thread connecting mode, and conveniently detachable again, the setting of retaining ring then can be fixed on LED direct current indicator lamp on the panel of each electric appliances and instrumentation easily.
The setting of movable bottom then is more convenient for the assembling of product.
Arcwall face is made on the surface of the utility model lampshade, the then feasible again visual angle that the utlity model has broad.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further
Accompanying drawing 1 is a structural representation of the present utility model
Accompanying drawing 2 is the partial enlarged drawing of accompanying drawing 1
Accompanying drawing 3 is circuit theory diagrams of the present utility model
The specific embodiment:
The following stated is a preferred embodiment of the present utility model, but does not therefore limit protection domain of the present utility model.
See shown in accompanying drawing 1 and the accompanying drawing 2, the utility model comprises a plurality of LED luminous tubes 30 that are arranged on the serial or parallel connection on the circuit board, housing 10 and the lampshade 20 that is contained in housing 10 upper ends, the lower end of housing 10 is provided with the bottom made from insulating materials 40, the outer wall both sides of this bottom 40 form and are convexly set in the chimeric groove 41 of snap ring 11 of housing 10 inner face both sides, in addition, the installation of bottom 40 for convenience, on the lateral wall of bottom 40, also offer gathering sill 42, then convex with the gib block 12 that cooperates with gathering sill 42 on the inner face of housing 10, during installation, make gathering sill 42 alignment guide bars 12, the lower ending opening of bottom 40 from housing 10 is pressed into, snap ring 11 is snapped in the groove 41, bottom 40 can be fixed on housing 10 bottoms.Bottom 40 is provided with binding post or binding post 50, connects the DC voltage of 5V～24V after LED luminous tube 30 is connected with resistance 60 by binding post or binding post 50.Color of light such as that LED luminous tube 30 has is red, green, yellow, blue, orange are selective, the information, the state that are applicable to various electric equipments, instrumentation show, can directly substitute the various voltage direct current indicator lamps of 5V～24V, also can be spliced into light emitting array or be spliced into symbol, literal.
The resistance of resistance of the present utility model can be calculated according to following formula: R=(U1-U2)/I
Wherein: U1 is outside input direct voltage, and U2 is a LED luminous tube forward voltage drop sum, and I is a rated operational current.
Example 1: when lamp is worked under the 12V DC voltage, if I is 20mA, R=(U1-U2)/I=(12-10.8)/0.02=60 Ω then.
