CN2198739Y - High efficiency daylight lamp - Google Patents

Abstract

The utility model relates to a high efficiency fluorescent lamp, which is composed of a fluorescent tube ROG, diodes D1, D2, capacitors C1, C2 and resistors R1, R2. The traditional ballast and starter are omitted, and the fluorescent tube needs only to connect one tube foot of each of both sides with an external circuit. The utility model has low manufacture cost, reliable work, low electricity consumption, small maintenance load, small volume and light weight and can save metallic material. Owing to high power factor, rapid starting, no flashing, no noise, the service life of the lamp tube is extended, the utility model can not only make use of the waste lamp tube, wherein, the filament of which is broken, and the lamp tube manufacturers even need not to arrange filaments in the lamp tubes but only lead out a tube foot from each of both ends.

Description

High efficiency daylight lamp

The utility model relates to a kind of fluorescent lamp tool.

As everyone knows, traditional fluorescent lamp tool has all used ballast and starter, ballast has that manufacturing cost is higher, power consumption is big, will consume shortcomings such as metal material, big and heave, and starter then is a consumable accessory, needs often to change and influences the reliability of daylight lamp circuit work.The fluorescent lamp tool of this use ballast and starter, also very strict to the requirement of fluorescent-lamp tube, in case the filament of fluorescent tube damages, then fluorescent tube just can not start luminous and must in time change.

Above-mentioned defective at the prior art existence, the purpose of this utility model, provide a kind of the cancellation whether to have the intact filament can both normally luminous High effective fluorescent light light fixture in ballast and starter and the fluorescent tube no matter be, make that simultaneously it is cheap, reliable operation, electricity consumption is saved, and lamp tube service life prolongs.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is circuit theory diagrams of the present utility model.

Referring to Fig. 1, solution of the present utility model is as follows. It still has fluorescent tube RDG, and its feature part also has diode D₁With D₂, capacitor C₁With C₂And resistance R₁With R₂，D ₁Positive pole and D₂Negative pole be connected in terminals 1, C₁An end and C₂An end be connected in terminals 2, D₁Negative pole and C₁The other end, R₁An end be connected in common port 3, D₂Positive pole and C₂The other end, R₂An end be connected in common port 4, R₁The other end, R₂The other end is connected to common port 5 and common port 6 mutually with the pin at fluorescent tube RDG two ends respectively.

Have the utility model of foregoing circuit structure when concrete the use, its terminals 1 and terminals 2 are joined with the 220V electric main, so diode D₁、D ₂Respectively conducting, electric current is to C₁、C ₂Conduct electricity respectively C₁、C ₂On voltage be charged to respectively the peak value of supply voltage, C₁、C ₂Again to pass through R after the series connection₁And R₂Be attempted by fluorescent tube RDG two ends. So just, so that starting moment, the two ends of fluorescent tube RDG are because D₁、D ₂Voltage multiplying rectifier produce one 2 * 220 $\sqrt{2}$ The voltage of V can make the mercury vapor ionization among the fluorescent tube RDG, sends ultraviolet ray and shines the fluorescence tube wall, sends visible light. After the fluorescent tube RDG normal operation, C₁、C ₂Two electric capacity play metering function, R₁、R ₂Add in order to overcome flicker. Utilize this circuit structure starting fluorescent tube, need not filament cathode heating process. Although the starting transient voltage is high, electric current is quite little, capacitance current-limiting after the starting, and the voltage of lamp tube ends only has 105V ± 3%, and this voltage is not high voltage, meets safety utilization of electric power.

A kind of most preferred embodiment of used electronic devices and components parameter is among Fig. 1: for the fluorescent tube of 40W-30W, R ₁=R ₂=200 Ω, 25W; C ₁=C ₂=3.5-4 μ F, 400V; D ₁=D ₃〉=300mA, 1000V; During operate as normal, fluorescent tube RDG both end voltage 105V ± 3%, open circuit voltage 400V ± 5%.For the fluorescent tube of 25W-15W, R ₁=R ₂=200 Ω, 20W; C ₁=C ₂=2.5 μ f, 400V; D ₁=D ₂〉=300mA, 1000V.

The utility model replaces existing ballast and starter with simple several electrons components and parts, not only make low cost of manufacture, reliable operation, electricity consumption saving, maintenance load reduce, save metal material and accomplished that body is in a small amount light, and improved the power factor of electrical network, starting then almost the same rapidly with incandescent lamp, energized is just bright, the flicker free process, noiselessness.Because fluorescent tube only needs a pin and outside line to join, thus fluorescent tube inside have or not intact filament all can, as long as fluorescent tube is broken and inner fluorescent material in addition, the waste fluorescent lamp of fracture of wire also can use for a long time, this has just prolonged the useful life of fluorescent tube greatly.Even the producer that produces fluorescent tube needn't be provided with filament in fluorescent tube inside, and only needs respectively draw a pin just in lamp tube ends.
