Description
Technical field
The utility model relates to illuminating LED daylight lamp, is specially the LED daylight lamp of compatible daylight lamp bracket.
Background technology
The internal circuit schematic diagram of existing fluorescent lamp as shown in Figure 1, this circuit comprises fluorescent tube, starter and ballast L, fluorescent tube comprises the first daylight lamp base, second day light modulation pin, 3rd daylight lamp base and the 4th daylight lamp base, first daylight lamp base and the 3rd daylight lamp base are used for and external communication electrical connection, first daylight lamp base and external communication electrical interconnection are also connected with ballast L, starter is connected with between second day light modulation pin and the 4th daylight lamp base, during use, fluorescent lamp is loaded on daylight lamp bracket, after external communication electrically connects, voltage is added to the two ends of starter, neon is made to discharge and send aura, the heat that aura produces makes the expansion of U-shaped movable contact spring extend, connect with static contact, so the filament in ballast coil and fluorescent tube just has electric current to pass through, after circuit ON, neon in starter stops electric discharge, (starter dividing potential drop is few for U-shaped cooling meat, glow discharge cannot be carried out, do not work), two contacts are separated, circuit disconnects automatically.In the moment that circuit disconnects suddenly, because ballast circuit sharply reduces, very high self induction electromotive force can be produced, direction is identical with original voltage direction, self induction electromotive force and supply voltage are added together, and form an instantaneous high pressure, are added in fluorescent tube two ends, the gas in fluorescent tube is made to start electric discharge, so the path that fluorescent lamp becomes electric current starts luminescence.When fluorescent lamp starts luminescence, because alternating current is by the coil of ballast, will produce self induction electromotive force in coil, it always hinders curent change, and at this moment ballast plays a part step-down current limliting, ensures that fluorescent lamp normally works.
As known from the above, when starting ballast and starter effect under can produce the high pressure (can more than 400V be reached) of a moment, when normally lighting, ballast plays the effect of pressure-limit current-limit, and output voltage lying prostrate more and do not wait (different according to the fluorescent lamp of different size) tens to one hundred.If therefore do not taken down, ballast and starter are just direct accesses daylight lamp bracket by LED daylight lamp, then may there is following situation: 1.LED fluorescent tube is directly just broken by high pressure, 2. LED fluorescent lamp tube can normally be lighted, but the life-span of LED fluorescent lamp tube has no idea to ensure (reason: in fluorescent tube start-up course, the high pressure at ballast two ends can be to estimate to the impact of LED daylight lamp), and the power of loss 7-8W wanted by ballast itself, do not reach energy-conservation object, there is flicker in 3.LED fluorescent tube, the phenomenon even do not worked.
Summary of the invention
The utility model, in order to solve the problem that traditional fluorescent lamp frame and LED daylight lamp cannot be compatible, provides the LED daylight lamp of compatible daylight lamp bracket.
The utility model adopts following technical scheme to realize: the LED daylight lamp of compatible daylight lamp bracket, comprise LED fluorescent lamp tube, starter and ballast L, LED fluorescent lamp tube comprises the first daylight lamp base, second day light modulation pin, 3rd daylight lamp base and the 4th daylight lamp base, first daylight lamp base and the 3rd daylight lamp base are used for and external communication electrical connection, first daylight lamp base and external communication electrical interconnection are also connected with ballast L, starter is connected with between second day light modulation pin and the 4th daylight lamp base, first daylight lamp base is connected with the positive pole of first crystal diode D1, the negative pole of first crystal diode D1 is connected with one end of electric capacity C, the other end of electric capacity C is connected with the positive pole of the 3rd crystal diode D3, the negative pole of the 3rd crystal diode D3 is connected with the 3rd daylight lamp base, second day light modulation pin is connected with the positive pole of the second crystal diode D2, the negative pole of the second crystal diode D2 is connected with the negative pole of first crystal diode D1, 4th daylight lamp base is connected with the negative pole of the 4th crystal diode D4, the positive pole of the 4th crystal diode D4 is connected with the positive pole of the 3rd crystal diode D3, the negative pole of first crystal diode D1 is the positive pole pin in LED fluorescent lamp tube, the positive pole of the 3rd crystal diode D3 is set to the negative pole pin in LED fluorescent lamp tube.
During use, this LED daylight lamp is arranged on daylight lamp bracket, after electrically connecting with external communication, due to daylight lamp base being connected with diode, by ballast L is direct current, ballast L is equivalent to resistance, do not play other effect, starter separates by diode in addition, and starter cuts little ice, LED daylight lamp can normally use, and electric capacity C can when outside alternating current commutation for LED daylight lamp provides forward voltage.
The utility model provides the LED daylight lamp of compatible daylight lamp bracket, and this LED daylight lamp is improved on existing LED fluorescent lamp tube basis, and make LED daylight lamp after access daylight lamp bracket, LED daylight lamp can normally use.
