Problems solved by technology

[0006] Two, low efficiency
The electro-optic conversion efficiency of the light bulb of the fire emergency lighting lamp in the prior art is low, and a large amount of electric energy is consumed in the form of heat energy or invisible light; the efficiency of the voltage inverter conversion circuit is low, and a large amount of electric energy is consumed in the form of heat energy
The low efficiency is also the reason for the need to equip large-capacity batteries
[0007] 3. The safety performance is not high
In the prior art fire emergency lights, a large amount of electric energy is converted into heat energy, which itself brings fire safety hazards, and the large-capacity battery equipped with it is easy to explode and catch fire when exposed to high temperature, which accelerates the spread of the fire
[0008] 4. Inconvenient to use
However, fire emergency lights are designed for emergency use, and inconvenient use will affect the efficiency of firefighters in responding to emergencies

Embodiment 1

[0022] like image 3 Shown is the control schematic diagram of the bulb 6 used for street lamp lighting when the mains power is normal. As shown in the figure, the light bulb 6 is connected to the mains through a switch, and the on-off state of the switch is controlled by the control circuit; the battery is a nickel-cadmium battery of the model "SC-1800MAH / 6V", which is also connected to the control circuit, and the control circuit passes the logic The chip and voltage comparator control the charging and discharging of the battery and realize overcharging and overdischarging protection: when the battery voltage is stable at 6V, stop charging; when the battery voltage is lower than 1V, stop discharging. The white LED diode 7 is connected in parallel to the output terminal of the battery through a switch, and the on-off state of the switch is controlled by the control circuit: when the mains voltage is lower than 132V, the switch is closed, and the battery lights up the white LE...

Embodiment 2

[0024] like Figure 4 Shown is the control schematic diagram of the bulb 6 used as a searchlight. As shown in the figure, the light bulb 6 is connected to the control circuit through a switch, the power supply of the light bulb 6 is provided by the battery, and the switch is controlled by the control circuit to control the on-off state; To the control circuit, the control circuit controls the charging and discharging of the battery through a logic chip and a voltage comparator, and realizes overcharging and overdischarging protection: when the battery voltage is stable at 6V, stop charging; when the battery voltage is lower than 1V, stop discharging. The white LED diode 7 is connected in parallel to the output terminal of the battery through a switch, and the on-off state of the switch is controlled by the control circuit: when the mains voltage is lower than 132V, the switch is closed, and the battery lights up the white LED diode; when the mains voltage is not lower than 132...

Abstract

The invention relates to a lamp, in particular to an LED fire emergency down lamp, which comprises a storage battery, a control circuit, a pilot lamp, and a white light LED diode. All components are fixed on a bracket of the down lamp and the white light LED diode is taken as a luminous source. The storage battery directly outputs direct current to the white light LED diode without voltage conversion during the outputting, so that the technical problem of low efficiency in the prior art is solved; moreover, the white light LED diode belongs to a cold light source and further guarantees electric light conversion efficiency; and the high electric light conversion efficiency correspondingly brings advantages of low power consumption and low cost. The LED fire emergency lamp can be widely used in fire fighting systems of high rise buildings and public places such as hotels, public houses, shopping markets and the like.

Description

technical field [0001] The invention relates to a lamp, in particular to an LED fire emergency lighting lamp. Background technique [0002] According to current regulations, building fire exits must be equipped with fire emergency lights. The most basic requirements for fire emergency lights are: when the mains is connected, the battery can be charged; when the mains is disconnected, the bulb can be automatically lit. Provide lighting. [0003] The bulb of present fire emergency lighting lamp mainly is incandescent bulb or fluorescent lamp. In order to improve the brightness and reduce the current (excessive current will easily cause the circuit board to heat up, cause energy loss and bring new safety hazards), the usual practice is to convert the voltage of the battery into 110V or 220V AC voltage. [0004] In general, the prior art fire emergency lighting has the following disadvantages: [0005] 1. High cost. The prior art fire emergency lighting includes a charging c...
