Abstract
The utility model provides a colorful LED underwater lamp. A detachable ring-shaped lamp cover and a sealing shell form an airtight body by a light-transmission glass and a sealing rubber ring; a circuit board arranged in the sealing shell is composed of a plurality of LED light emitting units with the same arraying structure; in the same unit, light spots of all LEDs are imaged in an overlapped manner to generate a colorful effect in eyes of appreciators due to spaces among the LEDs. Control circuits used for controlling light emission of the LEDs are respectively arranged on the circuit board, and a lead-out wire of the circuit board is communicated with an external cable by an insulated sealing layer and a sealing joint. The advantages of the colorful LED underwater lamp are as follows: colors that can be displayed are not limited by the own colors of the LEDs, and the display colors of the decorative lamp can be changed through proper control circuits; the sealing effect of the lamp is enhanced, water cannot easily enter the lamp, and the LEDs and other relevant circuits in the lamp can be protected from being damaged.
Description
Technical field
The utility model relates to a kind of lampion under water, and particularly a kind of LED that is used for light decoration under water is lamp under water.
Background technology
Along with the development of modern lamp decoration engineering, emerge diversified lamp decoration under water and light fixture on the market, existing LED ornament lamp generally is made up of the shell of printing opacity, cover plate, circuit board and the LED fluorescent tube that shell is removed.The shell of the light that the LED luminous tube of this ornament lamp sends by printing opacity to around penetrate and the external cable line of this ornament lamp directly is communicated with the circuit board lead-out wire by the cable-through hole that is arranged on the shell, though cable-through hole still is provided with sealing ring and seal cover, but in as the process that lamp uses under water, water can immerse along the SMIS of cable in the capsul, cause electric leakage, damage electrical appliance in the shell; Color that the more important thing is lamp is single, display mode is dull, color is abundant inadequately.
Summary of the invention
The purpose of this utility model provides a kind of colorful formula LED lamp under water, and it can send colorful light, and prevents into water, LED and interlock circuit thereof in the protection light fixture.
For achieving the above object, the utility model provides a kind of colorful formula LED lamp under water, by capsul, annular light cover, clear glass, rubber seal, illuminating circuit and electric power connection line road are formed, and described dismountable annular light cover constitutes obturator by transparent glass, O-ring seal with capsul; Be arranged on the circuit board in the capsul and be made of the identical LED luminescence unit of a plurality of arrangement architectures, each luminescence unit is arranged with a red light emitting diodes, a green LED and a blue LED at least; In same unit, the light emitting diode tube pitch makes hot spot colorful effect of the overlapping generation of imaging in appreciator's eye of all light emitting diodes; The luminous control circuit of control LED luminous tube all is arranged on the circuit board, and the lead-out wire of circuit board is communicated with external cable by insulated enclosure layer, seal nipple.
Described illuminating circuit comprises the luminous site that light emitting diode matrix constitutes, specifically light emitting diode matrix is made of the identical luminescence unit of a plurality of arrangement architectures, and each luminescence unit is arranged with a red light emitting diodes, a green LED and a blue LED at least; In same luminescence unit, the light-emitting diodes tube pitch makes that hot spot imaging in appreciator's eye of all light emitting diodes is overlapping; The centre-to-centre spacing of adjacent luminescence unit is identical, and this centre-to-centre spacing satisfies following formula: D 〉=2*L*tan (θ/2), D is the minimum centers-distance of adjacent luminescence unit in the formula, and L watches some the vertical range with the luminous site of ornament lamp during for normal the use, and θ is the human eye angle of minimum resolution.Owing to had above-mentioned arrangement characteristics by the light emitting diode matrix of utility model, therefore ornament lamp demonstrates abundant colors in the time of can be by control circuit: shell is controlled the three kinds of shared ratios of color of red, green, blue in each luminescence unit, just can make each luminescence unit mix multiple different color, if the different luminescence units of inner control demonstrate different colors at one time, just can make the whole luminous site of ornament lamp be the bright-colored effect of ready-made brilliance.
Described power circuit is arranged at the capsul bottom, and the lead-out wire of circuit board is communicated with external cable by lead, the seal nipple in the insulated enclosure layer.The insulated enclosure layer is to be used in the water the stable insulating materials of physicochemical property to make, and lead firmly fixed by injection or pressing process is sealed in the insulated enclosure layer, invades in the capsul from insulated enclosure layer and lead to prevent water.
The utility model has the advantages that displayable color is not subjected to the restriction of light emitting diode self color, only need just can change the display color of ornament lamp by suitable control circuit, and need not to change light emitting diode, and only need adjust control program and just can realize the dynamic continually varying effect of color.And need not to change the array structure of luminescence unit and the arrangement architecture of luminescence unit interior light emitting diodes; Strengthened the sealing effectiveness of light fixture, light fixture is difficult for water inlet, and LED and interlock circuit thereof in the protection light fixture are not destroyed.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of lamp socket.
Among the figure: 1. capsul; 2. annular light cover; 3. transparent glass; 4. O-ring seal; 5. circuit board; 6.LED luminous tube; 7. seal nipple; 8. insulated conductor; 9. insulated enclosure layer; 10. external cable.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, 2, the utility model is made up of capsul 1, annular light cover 2, transparent glass 3, O-ring seal 4, illuminating circuit and electric power connection line road, it is characterized in that: constitute obturator by transparent glass 3, O-ring seal 4 with capsul 1 by dismountable annular light cover 2; Be arranged on the circuit board 5 in the capsul 1 and be made of the identical LED luminescence unit of a plurality of arrangement architectures, each luminescence unit is arranged with a red light emitting diodes, a green LED and a blue LED at least; In same unit, the light emitting diode tube pitch makes hot spot colorful effect of the overlapping generation of imaging in appreciator's eye of all light emitting diodes; Control LED luminous tube 6 luminous control circuits all are arranged on the circuit board 5, and the lead-out wire 8 of circuit board 5 is communicated with external cable 10 by insulated enclosure layer 9, seal nipple 7.
Luminous component of the present utility model is enough become by a plurality of luminescence units, and the arrangement architecture of each luminescence unit is identical.In same luminescence unit, the light-emitting diodes tube pitch should make as far as possible that hot spot imaging in appreciator's eye of all light emitting diodes is overlapping, to reach uniform color matching effect; The centre-to-centre spacing of adjacent luminescence unit is identical, and this centre-to-centre spacing satisfies foregoing formula, so just can make the audience clearly tell the color that adjacent luminescence unit shows under the distance normally viewing and admiring.
