Abstract
An emergency light is provided which can automatically operate in case of a need for an emergency lighting. It essentially consists of an automatic charging circuit, a standby storage cell, an automatic switchover circuit to make the light source on or off and a light source which are all electrically connected. Two or more switches of parallel connection are equipped at the circuit by which the standby storage cell powers the light source. Among the parallel connection of switches, at least one is equipped outside of a protective box for the emergency light and keeps connection with a circuit in the emergency light via a conductor.
Description
Affiliated technical field
The utility model relates to a kind of light fixture that can realize emergency lighting when the mains-supplied interruption takes place automatically, especially can be achieved as follows the light fixture of function: when the occasion at this light fixture place needs emergency lighting and mains-supplied takes place to interrupt, this light fixture is realized emergency lighting automatically, when the occasion at this light fixture place does not need emergency lighting, interrupt even mains-supplied takes place, this light fixture is not realized emergency lighting automatically.
Background technology
At present, the structure of known emergency light mainly is by automatic charger, standby battery, and light source is bright, put out automatic switch-over circuit and light source is electrically connected to form.Emergency light is connected on the utility grid, when mains-supplied just often, automatic charger charges to standby battery automatically, light source is bright, put out automatic switch-over circuit makes standby battery be in open-circuit condition to the circuit of light source transmission of electricity, light source is in and extinguishes state, when mains-supplied is interrupted, automatic charger stops to charge to standby battery, light source is bright, put out automatic switch-over circuit switches to closed circuit state to standby battery to the circuit of light source transmission of electricity by open-circuit condition automatically, light source is luminous because of the electric energy that obtains standby battery, and emergency light is realized emergency lighting.The shortcoming of general emergency light is: as long as mains-supplied is interrupted, emergency light will be realized emergency lighting automatically, no matter whether the occasion at emergency light place needs emergency lighting, has caused waste of electric energy and the service life that has shortened emergency light.
Summary of the invention
Have emergency light now as long as mains-supplied interrupts realizing emergency lighting automatically in order to overcome, cause waste of energy and shorten the emergency light deficiency in service life, the utility model provides a kind of emergency light, this emergency light can be achieved as follows function: when the occasion at emergency light place needs emergency lighting and mains-supplied takes place to interrupt, emergency light is realized emergency lighting automatically, occasion when this emergency light place does not need emergency lighting, even mains-supplied takes place interrupts, emergency light can not realized emergency lighting automatically, when people need use this emergency light as portable lighting, as long as this emergency light and utility grid are broken away from, just can be as using flashlight to use this emergency light.
The technical scheme that the invention for solving the technical problem adopted is: in guard box; automatic charger; standby battery; light source is bright; putting out automatic switch-over circuit and light source is electrically connected; the switch of two or more parallel connections transmitting electricity circuit to light source on, standby battery is set; wherein at least one switch is arranged on outside the guard box; this switch is connected by the circuit of the emergency light in lead and the guard box; other switch is arranged in the guard box; make that standby battery is to be in open-circuit condition or closed circuit state to the circuit of light source transmission of electricity, is determined jointly by the bright state that puts out the switch of automatic switch-over circuit and above-mentioned parallel connection of light source.When emergency light is installed, is installed in the next door of just using the switch of illuminating lamp always being arranged on the outer switch of emergency light guard box, and makes the switch of above-mentioned parallel connection all be in off-state.Open when just using illuminating lamp always when the needs lighting; in passing the outer emergency light switch of guard box that is arranged on the switch next door that is installed in illuminating lamp just commonly used is switched to closure state by off-state; at this moment; standby battery is to be in open-circuit condition or closed circuit state is bright by light source to the circuit of light source transmission of electricity; put out the automatic switch-over circuit decision; if mains-supplied is normal; light source is bright; putting out automatic switch-over circuit makes standby battery be in open-circuit condition to the circuit of light source transmission of electricity; if mains-supplied is interrupted; light source is bright; put out automatic switch-over circuit and automatically the circuit that standby battery is transmitted electricity to light source is switched to closed circuit state by open-circuit condition; light source luminescent; realize emergency lighting; when closing just commonly used illuminating lamp because do not need lighting; in passing the outer emergency light switch of guard box that is arranged on the switch next door that is installed in illuminating lamp just commonly used is reverted to off-state by closure state; at this moment; all be in open-circuit condition because be arranged on the standby battery of emergency light to the switch on the circuit of light source transmission of electricity; so; no matter whether mains-supplied interrupts; standby battery all is in off-state to the circuit of light source transmission of electricity, and light source all is in and extinguishes state.When needs use emergency light as portable lighting; this emergency light and utility grid disengaging are come; the standby battery that is arranged in the guard box is switched to closure state to any one switch in the switch in parallel on the circuit of light source transmission of electricity by off-state; at this moment; this switch and light source be bright, put out automatic switch-over circuit makes standby battery switch to closure state to the circuit of light source transmission of electricity by off-state jointly; light source is in luminance, realizes portable lighting.
The beneficial effects of the utility model are: only when the needs emergency lighting, emergency light is just realized emergency lighting automatically, has saved electric energy, has prolonged the service life of emergency light, simultaneously, can use this emergency light as a kind of movably emergency light.
