Abstract
The invention discloses an emergency LED fluorescent lamp, which is characterized in that the fluorescent lamp comprises a lamp holder, lamp caps and an LED fluorescent lamp tube, wherein the lamp caps are arranged at two ends of the lamp holder, two ends of the LED fluorescent lamp tube are arranged on the lamp caps, and the lamp holder is provided with a driving circuit and a rechargeable nickel-metal hydride battery. The driving circuit has the function of identifying environmental light intensity, has the functions of constant current output, emergency and charge at the same time, supplies power to the LED fluorescent lamp tube and charges the nickel-metal hydride battery under the condition of normal power supply, and supplies the electric energy of the battery to the LED fluorescent lamp tube under the condition of power failure; and the rechargeable nickel-metal hydride battery stores power supply for the LED fluorescent lamp tube and provides electric energy for the LED fluorescent lamp tube under the condition of power failure.
Description
Technical field
The present invention relates to a kind of fluorescent lamp, specifically a kind of emergency type LED fluorescent lamp with environment-identification light power.
Background technology
LED is that light emitting diode is a kind of semiconductor solid luminescence device, and it is to utilize the solid semiconductor chip as luminescent material, by carrier compound energy of emitting surplus takes place and caused photo emissions in semiconductor, directly sends the light of white.Characteristics such as the LED lamp is low with its operating voltage, little power consumption, long service life obtain liking of numerous users, extensively are used in the place that need light for a long time.At present, people combine the plurality of LEDs lamp and are installed in the fluorescent lamp, utilize the stack of brightness, reach the brightness identical with common fluorescent lamp.Under current energy starved situation, but the green light source product of this energy savings is a development in future trend.
Summary of the invention
The purpose of this invention is to provide a kind of emergency type LED fluorescent lamp with environment-identification light power.
Purpose of the present invention is achieved through the following technical solutions:
A kind of emergency LED fluorescent lamp is characterized in that: described fluorescent lamp comprises lamp bracket, lamp holder and LED fluorescent tube, and lamp holder is arranged on the two ends of lamp bracket, and the two ends of LED fluorescent tube are installed on the lamp holder, and drive circuit and rechargeable nickel-hydrogen battery are installed on the lamp bracket; Described drive circuit comprises control circuit, constant-current circuit, charging circuit, converter and sensor devices, and control circuit is electrically connected with constant-current circuit, charging circuit, converter and sensor devices, and charging circuit is electrically connected with rechargeable nickel-hydrogen battery.
Drive circuit in the LED fluorescent lamp of the present invention has the function of environment-identification light power simultaneously, the constant current output function, emergency function and charge function, drive circuit for the power supply of LED light pipe and to the Ni-MH battery charging, is supplied with the LED fluorescent tube with the electric energy of battery under the situation of outage under the situation of normal power supply; Rechargeable nickel-hydrogen battery is a LED fluorescent tube redundant electrical power, for the LED fluorescent tube provides electric energy under the situation of outage.
Description of drawings
Fig. 1 is the structural representation of emergency LED fluorescent lamp of the present invention;
Fig. 2 is the circuit block diagram of emergency LED fluorescent lamp of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing emergency LED fluorescent lamp of the present invention is described in further detail.
As shown in Figure 1, emergency LED fluorescent lamp shown in the present mainly is made up of lamp bracket 1, lamp holder 2, LED fluorescent tube 3, rechargeable nickel-hydrogen battery 4 and drive circuit 5.Lamp holder is installed in the two ends of lamp bracket, and the two ends of LED fluorescent tube are installed on the lamp holder, and drive circuit and rechargeable nickel-hydrogen battery are positioned at the cavity of lamp bracket, and a cover plate is installed on the cavity, and rechargeable nickel-hydrogen battery is connected with drive circuit.
Circuit theory as shown in Figure 2, control circuit at first detects the signal of being sent here by photoreceptor, debate other ambient light intensity, can not start illumination if light is very strong, carry out following work if light is very weak: under the normal situation of civil power, civil power divides the two-way confession behind the AC-DC converter, and one the tunnel gives the power supply of LED fluorescent tube through the DC-DC constant-current circuit, one the tunnel charges to Ni-MH battery through the DC-DC charging circuit, and they are sent voltage signal respectively and give control circuit simultaneously; When civil power cut off the power supply, control circuit started emergency function after detecting this variation automatically, and Ni-MH battery is powered to fluorescent tube through control circuit and DC-DC constant-current circuit.
This emergency LED fluorescent lamp advantage:
1. have the battery automatic protection functions, when cell voltage dropped to 10V, the autoshutdown battery protected battery not damaged by over-discharge when emergent. Adopt 1/10C electric current constant-current charge and pressure limiting charging during charging, can not generate heat when guaranteeing the battery charging and also can not damage because overcharging.
2. the function that has automatic identification daytime and night, during daytime or surround lighting can not start illumination when very strong, can not start emergency function having a power failure in such cases yet; Only have at night or surround lighting starts illumination when very weak, just can start emergency function having a power failure in such cases, and can preestablish the induction of light.
3. has the power factor height, efficient height, the characteristics such as energy-conservation
4. adopt design of material, the manufacturing of environmental protection, all material of LED light fixture is the material of nontoxic and contaminated environment, meets RoHS Directive, meets the countries in the world environmental requirement, most material recoverables.
5. the LED that adopts the low light decay of high brightness is as light source, and the life-span is long.Easy for installation flexible, be applicable to places such as various industrial civil buildings, office, school, hospital, army, miner's temporary lighting.
