Abstract
The utility model provides a DC integrated energy-saving emergency lamp, which comprises an energy-saving fluorescent tube. An oscillating circuit power supply end is connected with a low-voltage DC power supply. An output end of a step up transformer of the oscillating circuit is connected with the fluorescent tube. The utility model applies the energy-saving fluorescent tube to the emergency lamp, and has the advantages of energy-saving effect and convenient usage, provides more than doubled prolonged service life with the same DC power supply and the light is brighter than that of an incandescent lamp.
Description
Technical field:
The utility model relates to light fixture, particularly to the improvement of emergency light.
Background technology:
Temporary lighting usefulness when emergency light is used to have a power failure generally uses 6V～12V storage battery as the energy, adopts incandescent miniature bulb, or claims small electric bulb, and light is darker.Because the incandescent light optoelectronic conversion ratio is very low, the power supply supply time is short.And the high power saving fluorescent lamps of photoelectric conversion rate can only adopt the 220V AC power.
Summary of the invention:
The purpose of this utility model is a kind of employing energy-saving fluorescent lamp of design, by the energy-conservation emergency light of low-voltage dc power supply power supply.
The utility model comprises energy-saving fluorescent lamp, it is characterized in that the oscillation circuit power end is connected with low-voltage dc power supply, and the output of the step-up transformer of oscillating circuit connects fluorescent tube.Energy-saving fluorescent lamp is connected with plug by circuit box, and the miniature bulb socket of plug shape, size and emergency light matches, and wherein the oscillation circuit power end is connected with negative pole with the positive plate of plug by lead respectively.
The utility model will save the lamp fluorescent tube and be applied on the emergency light by step-up transformer, make it to have energy-conservation, advantage easily, and with identical DC power supply, can prolong more than one times service time, and light is brighter than incandescent lamp.
Description of drawings:
Fig. 1 is the utility model functional-block diagram.
Fig. 2 is the embodiment electrical schematic diagram.
Fig. 3 is the shape figure of embodiment lamp.
Embodiment:
Embodiment adopts two pliotron Q1 and Q2 and high frequency transformer B to form self-maintained circuit K, and its operating voltage is provided by low-voltage dc power supply E, is generally 6V～12V storage battery.B boosts into high-frequency and high-voltage power supply by transformer, is added to energy-saving fluorescent lamp D two ends and makes it to light.Oscillating circuit K is contained in the circuit box 3, and its transformer B high-voltage output end is connected with fluorescent tube D, and the positive pole 1 of power saving fluorescent lamps D plug connects the operating voltage end among the oscillating circuit K, and the negative pole 2 of fluorescent tube D plug connects the ground end of oscillating circuit K.
Q1 in the circuit, Q2 two pipe models, service behaviour parameter basically identical, but still some discreteness.After circuit is connected DC power supply, because some difference of performance of two pipes causes a pipe conducting in advance wherein, makes electric current flow through primary coil, and therefore in the coil that links to each other, induce electric current, the current opposite in direction on direction and former limit, when the electric current that induces is increased to certain the time, the pipe of original conducting ends, another pipe conducting, go round and begin again, thereby induce the power supply of high-frequency and high-voltage, driving fluorescent lamp operate as normal at secondary.
The size of frequency depends on the inductance size on operation DC voltage, base stage branch pressure voltage and former limit etc., and the big I of power is adjusted (as increasing operating voltage, the power of pipe, the size of magnetic core etc.) according to actual needs, but the principle basically identical.
