Abstract

The utility model relates to a metallic halide color changing lamp which is composed of a controller and light fixtures. The controller is composed of a signal generator, a signal splitter, an electronic switch, and a power supply, wherein, a red metallic halide bulb, a green metallic halide bulb and a blue metallic halide bulb in the light fixtures are placed oppositely and parallelly in a lamp shell in the form of two to one. Lamp holders are all placed on the both sides of the inner wall of the lamp shell. The color changing lamp can lead the metallic halide lamp to automatically change colors.

Description

The metal halide Color-changing lamp

The utility model relates to a kind of Color-changing lamp device of being made up of controller and the light fixture that red, green, blue three-colour light-emitting device is housed, and particularly can make metal halid projecting lamp change the Color-changing lamp device of color automatically.

Metal halide lamp has its characteristics than incandescent lamp and fluorescent lamp: the one, and start-up time is long, generally needs ten minutes more than; The 2nd, can't change its brightness with the height of control voltage, so can not start with pressure regulation.And existing Color-changing lamp control technology is only applicable to incandescent lamp and fluorescent lamp, its reason one is the start-up time that can't satisfy metal halide lamp, as China Patent No. is the no steady oscillator that its oscillating circuit of patent of 92209070.X is made up of not gate, also be that start-up time was no longer than one minute its cycle of oscillation; The 2nd, pressure regulation starts, and is " control the brightness of each photophore, change three coloured light mixing ratios " as described in the ZL92219414.9 specification as China Patent No..So just can't start metal halide lamp.

The purpose of this utility model provides a kind of device that can be suitable for the metal halide lamp variable color.

The purpose of this utility model is achieved in that the form opposing parallel of red, green, blue three non-ferrous metal halide lamps by 2 pairs 1 is positioned in the same lamp housing, and lamp socket all is placed in the envelope inner wall both sides.Its controller is by signal generator, and signal distributor, electronic switch and power supply are formed.Signal generator is to adopt time-base integrated circuit IC ₁With resistance R .W and capacitor C ₁, C ₂The no steady oscillating circuit of forming was not less than five minutes cycle of oscillation.The clock pulse signal of its output directly adds the input end of clock of signal distributor.Signal distributor is to adopt johnoson counter and or door integrated circuit composition.The output of johnoson counter with or the door integrated circuit input link to each other, work out control program as required and connect, to produce three color control signals.Three color control signals add the input of electronic switch from the output of signal distributor.Electronic switch is by resistance R ₁, R ₂, R ₃With transistor E ₁, E ₂, E ₃And relay J ₁, J ₂, J ₃Form.From three color control signals of signal distributor input respectively through triode E ₁, E ₂, E ₃Amplify, so that enough power drive relay J to be provided ₁, J ₂, J ₃The power switch of control tri coloured lantern.

Because the signal generator that this device has adopted time-base integrated circuit to form, be can adjust significantly the clock signal period start-up time that makes this device, makes it to satisfy the start-up time of metal halide lamp.With johnoson counter and or the door integrated circuit form signal distributor, circuit is simple, strong interference immunity.Directly the power supply of metal halide lamp is carried out the switch switching with electronic switching circuit, adapted to the characteristics of metal halide lamp, make it to start stable.2 pairs 1 parallel being placed in relatively in the same lamp housing of three non-ferrous metal halide lamps, and lamp socket all is placed in the envelope inner wall both sides, made full use of the space in the lamp housing, improved three look registrations to greatest extent.

Below in conjunction with drawings and Examples the utility model is described in further detail:

Fig. 1 is the electrical schematic diagram of the utility model metal halide Color-changing lamp device middle controller.

Fig. 2 is the structural representation of light fixture in the utility model metal halide Color-changing lamp device.

The described controller of Fig. 1 (1) comprises by time-base integrated circuit 1C ₁With resistance R .W and capacitor C ₁, C ₂The clock-signal generator of forming, its clock pulses signal period is a capacitor C ₁The time constant that discharges and recharges be not less than five minutes, therefore, R 〉=500K Ω, W 〉=4.7M Ω, C ₁〉=250 μ F.This controller also comprises by Johnson's counting circuit IC ₂With or the door IC ₃The signal distributor of forming.Johnson's counting circuit IC ₂, available octal representation device CD4022, or door IC ₃Can be or the door can be nor gate also, as CD4025.This controller also comprises by resistance R ₁, R ₂, R ₃With transistor E ₁, E ₂, E ₃And relay J ₁, J ₂, J ₃The electronic switch of forming.IC in signal distributor ₃Be or when door transistor E ₁, E ₂, E ₃Use the NPN type, as 9013; Work as IC ₃When being nor gate, the transistor positive-negative-positive is as 9012.The output of signal generator (3) links to each other with the input end of clock (13) of signal distributor, three outputs (6) of signal distributor, (9), (10) respectively with the input resistance R of three electronic switches ₁, R ₂, R ₃Link to each other.Three color control signals of signal distributor output are through transistor E ₁, E ₂, E ₃Amplify, to drive relay J ₁, J ₂, J ₃The metal halide lamp power supply is carried out switch control.

Fig. 2 represents the structure of the light fixture (2) in the utility model metal halide Color-changing lamp device.Red, green, blue three non-ferrous metal halide lamps (4) are placed in the lamp housing (8) by 2 pairs 1 form opposing parallel, and lamp socket (5) all is placed in the inwall both sides of lamp housing (8).
