Abstract
The utility model relates to an LED bulb for a festival colour lamp. LED lamps are arranged on a circuit board in the space formed by a bulb casing and a lamp holder, a resistor or voltage reducing module is installed below the circuit board, the LED lamps and a control module on the circuit board are connected in parallel or in series, the control module is orderly connected in parallel with a rectifying bridge and connected in series with the resistor or in parallel with the voltage reducing module after connected in parallel with a voltage stabilizing tube, and two wiring points of the bulb are the same as wiring points of general festival colour lamps. As a light emitting source, the LED lamp has the advantages of extremely low power consumption, low caloric value, bright and pure color, high safety and high durability. A plurality of LED lamps with different colors are installed in one bulb casing to emit different colors, and colorful light emission can be achieved. The bulb casing is made of plastic and can dure extrusion, and the color and the shape can be easily deployed and patterned. The LED lamps can be controlled to realize conventional light emission and variation such as horse race, flicker, etc. through the switching of the control module.
Description
Affiliated technical field
The utility model relates to a kind of ornamental light fixture, particularly a kind of Colour lamp for fastival and holiday LED bulb.
Background technology
Present Colour lamp for fastival and holiday adopts tungsten filament to do light emitting source mostly, and caloric value is big during work, the power consumption height, and tungsten filament easily blows, and the bulb explosive causes fire easily, has unsafe factor; Required shades of colour is mainly brushed on the glass cell-shell by paint, and depainting phenomenon takes place in the use easily, causes photochromic impure; Cell-shell adopts glass to make raw material, takes place broken in production, transportation easily; In addition, appearance and modeling is more single, and service life is short.
The utility model content
The utility model purpose be to provide a kind of energy-conservation, caloric value is low, safe in utilization, color is various, long-lived Colour lamp for fastival and holiday LED bulb.
The technical scheme that the invention for solving the technical problem adopted is: a kind of Colour lamp for fastival and holiday LED bulb, comprise cell-shell, screw socket, cell-shell is contained in the screw socket, two wiring points of bulb, top at the lamp holder metal-back, one at the cap screw thread place, it is characterized in that: the LED lamp is contained on the circuit board in the space of cell-shell and lamp holder formation, resistance is installed under the circuit board, control module on LED lamp and the circuit board is in parallel or connect, control module is in parallel with voltage-stabiliser tube, and then order is connected with the rectifier bridge parallel connection, with resistance or be in parallel with the step-down module.
Described LED lamp can be a plurality of, and color can be with a kind of, also can have nothing in common with each other.
The material of described cell-shell is plastics.
The beneficial effects of the utility model are: it is extremely low that the LED bulb is made light emitting source power consumption, and caloric value is low, bright in luster pure, safe in utilization, durable in use; A plurality of LED lamps with color or different colours are installed in a cell-shell, can be sent identical or different color, satisfy people's different demands; It is raw material that cell-shell adopts plastics, anti-extruding, and color and shape can easily be allocated and moulding; The conversion control module can be controlled the LED lamp and realize conventional luminous and variations such as horse race, flicker.

Fig. 3 is the vertical section structural map of this practical second embodiment.
Fig. 4 is Fig. 3 embodiment circuit theory diagrams.
1. cell-shells among the figure, 2.LED lamp, 3. circuit board, 4. resistance, 5. lamp holder, 6. control module, 7. voltage-stabiliser tube, 8. rectifier bridge, 9. step-down module.
The specific embodiment
As shown in Figure 1, it is the structural map of low-voltage LED bulb, plastics cell-shell (1) is installed in the screw socket (5), both smear with marine glue the junction, screw socket (5) is the GB screw socket, two wiring points of bulb, the top at lamp holder (5) metal-back, one at lamp holder (5) screw thread place, identical with common Colour lamp for fastival and holiday; LED lamp (2) is contained on the circuit board (3) in the space of cell-shell (1) and lamp holder (5) formation, and resistance (4) is installed under the circuit board (3), resistance (4) one pin connecting circuit plates (3), and another pin connects the top of lamp holder (5) metal-back.
As shown in Figure 2, be the circuit theory diagrams of low-voltage LED bulb, LED lamp (2) lamp group in parallel is in parallel with control module (6), control module (6) is in parallel with voltage-stabiliser tube (7), back rectifier bridge in parallel (8) is series resistance (4) again, connect the 24V power supply at last, this low-tension supply is the power supply after handling through step-down.The 24V low-tension supply becomes the required low-voltage dc voltage of control module (6) through resistance (4) back voltage transformation, resistance (4) plays current limliting therein, and conversion control module (6) driving light emitting source LED lamp (2) can be realized luminous and realize functions such as horse race, variable color, flicker.Certainly, LED lamp (2) lamp group in parallel also can be connected, and can use equally.
As shown in Figure 3, be the structural map of high-voltage LED bulb, compared to Figure 1 only be the difference that the resistance (4) of series connection is replaced with step-down module (9) in parallel.
As shown in Figure 4, be the circuit theory diagrams of high-voltage LED bulb, to compare with Fig. 2 only be that step-down module (9) is playing that high pressure is reduced to low pressure with step-down module (9) resistance (4) that replaces series connection in parallel, LED lamp (2) lamp group still in parallel or connect.
Claims (3)
1. Colour lamp for fastival and holiday LED bulb, comprise cell-shell, screw socket, cell-shell is contained in the screw socket, two wiring points of bulb, the top at the lamp holder metal-back, one at the cap screw thread place, it is characterized in that: the LED lamp is contained on the circuit board in the space that cell-shell and lamp holder form, and resistance is installed under the circuit board, the control module parallel connection on LED lamp and the circuit board or connect, control module is in parallel with voltage-stabiliser tube, and then order is connected with the rectifier bridge parallel connection, with resistance or be in parallel with the step-down module.
