Description
Technical field
The utility model relates to a kind of lighting device, especially outdoor xenon light source illuminating lamp.
Background technology
Xenon lamp is called the multiple metal halide lamp of xenon again, belong to high-intensity gas discharge lamp (High IntensityDischarge Lamp, HID).Xenon lamp is to fill about 800～900kpa high-pressure xenon and multiple metal halide in the uvioresistant quartz glass tube.Under the excitation of the startup high pressure more than the 18-23KV, free electron obtains enough energy under the effect of electric field in lamp, remove colliding atom, make it discharge the more freedom electronics, thereby in the gas in lamp avalanche and discharge takes place, as long as extra electric field continues always, this avalanche and discharge phenomenon will continue always, thereby discharge electromagnetic wave, finally reach the luminous purpose of gas discharge.
At present, lighting source commonly used on the road is a high-pressure sodium lamp, and it is its high light efficiency with about 120Lm/W that road lighting is recommended to select the main foundation of high-pressure sodium lamp for use.But the light efficiency here is photopic vision (＞3cd/m
2) data of gained under the condition, along with the decline of luminance level, because its extremely low color rendering, high-pressure sodium lamp effective luminous efficacy and light efficiency coefficient can obviously reduce.External test confirms that under the road lighting condition light source that the light efficiency coefficient is big is more conducive to periphery and surveys.Now with nominal light efficiency 80Lm/W, color rendering index is 80 Metal halogen lamp and nominal light efficiency 116Lm/W, and color rendering index is that 20 high-pressure sodium lamp does one relatively: under the photopic vision condition, effective luminous efficacy is identical with nominal value, promptly be respectively 80Lm/W and 116Lm/W, the light efficiency coefficient all is 1; When luminance level is higher than 0.1cd/m
2The time, though the effective luminous efficacy of high-pressure sodium lamp descends to some extent, but still be higher than Metal halogen lamp; When luminance level is lower than about 0.1cd/m
2The time, Metal halogen lamp then begins to have higher effective light efficiency and light efficiency coefficient; Under the noctovision condition, the effective luminous efficacy of Metal halogen lamp approximately is 2 times of high-pressure sodium lamp, and the light efficiency coefficient approximately is 3 times of high-pressure sodium lamp.Be the reduction of high-pressure sodium lamp along with luminance level, effective luminous efficacy and light efficiency coefficient obviously reduce, and Metal halogen lamp effective luminous efficacy and light efficiency coefficient increase on the contrary.
The utility model content
In order to overcome the deficiency that existing illuminating lamp exists, the utility model provides a kind of novel outdoor xenon light source illuminating lamp, and it is integrated by many small-power xenon lamp point-source of lights, and driving power is the permanent power xenon lamp of a novel civil power electron rectifier, and input power factor is 1.It is a kind of effective luminous efficacy height, the life-span is long, light pollution is little, energy savings, and meets human visual experience's illuminating street lamp.
The technical scheme that its technical problem that solves the utility model adopts is: outdoor xenon light source illuminating lamp, the fixed insulation shell on the glass lamp on its left side and the right links together, the xenon wick of the inside is electrically connected by the high-tension circuit plate of conducting bracket and fixed insulation housings, right-hand member has the shielding insulation lead, is connected with the one drag two electron rectifier below.The left side is electromagnetic compatibility unit, power factor correction unit, single-ended reverse exciting pwm unit, full-bridge inverting unit, high-tension circuit unit successively, exchanges xenon lamp in the electron rectifier block diagram, is central control unit below the full-bridge inverting unit.
Operation principle is: the city is for alternating current process ingoing power factor correcting unit, electromagnetic compatibility unit, realize that in the electromagnetic compatibility unit external circuit suppresses electron rectifier and the electron rectifier electromagnetic interference to external circuit, alternating voltage is converted into direct voltage to power factor correction unit and input power factor is 1, this direct voltage provides controlled direct-current working volts by the single-ended reverse exciting pwm unit for this rectifier sequential, and the full-bridge inverting unit is converted into direct voltage and exchanges the specified ac square-wave voltage of xenon lamp; The high-tension circuit unit provides instant high-voltage to excite the interchange xenon lamp, and ac square-wave voltage is kept and exchanged the xenon lamp operate as normal; Central control unit provides comprehensive control; protection control is provided during, electron rectifier load abnormal unusual for alternating voltage in the city; before exchanging the xenon lamp operate as normal, provide controls such as detection, startup, adjustment, controls such as detection, permanent power are provided after the operate as normal.
The beneficial effects of the utility model are, this outdoor xenon light source illuminating lamp, and being used for road, airport, harbour, station and industrial and mining enterprises' illumination becomes possibility.Replace high-pressure sodium lamp with the utility model, can strengthen the effective luminous efficacy and the light efficiency coefficient of illuminating lamp greatly, reduce the night traffic accident rate, energy savings, xenon lamp spectrum and sunlight are very approaching simultaneously, reach the optimum visual impression.
