Abstract
The invention discloses an automatic power-off protection device during opening of a lamp cover of a lamp and relates to the technical field of production of high-power light emitting diode (LED) lamps. The automatic power-off protection device during the opening of the lamp cover of the lamp comprises a high-voltage direct current power supply, wherein a switch and an LED lamp are connected in series to the high-voltage direct current power supply; a group of high-power relays and travel switches are connected in series with each other and then connected in parallel to two ends of the switch and the LED lamp; and conversion switches are connected in parallel to the two ends of the travel switch. In the invention, the high-power relays are switched on or switched off by the travel switch, so the LED lamp is turned off or turned on; after the safety maintenance of an operator is finished, the conversion switch forcedly switches on the power to test the lamp; and maintenance safety can be guaranteed.
Description
Technical field
The present invention relates to the light fixture production technical field.
Background technology
Light fixture can break down after use, needs normally maintenance.But during owing to maintenance, there is potential safety hazard in high voltage source, is protection service worker safety, a kind of breaker device when opening the light fixture light cover in the time of need being provided at high-altitude energising maintenance.
Summary of the invention
The object of the invention is to open automatic power-off protection device for working service provides a kind of light fixture light cover that can cut off the power supply the short time.
The present invention includes high-voltage DC power supply, serial connection switch and LED light fixture on described high-voltage DC power supply is connected in parallel on the two ends of described switch and LED light fixture, at the two ends of described travel switch change over switch in parallel after one group of high power relay and the travel switch series connection.
The present invention makes the outage of LED light fixture or gives electricity by travel switch control high power relay on-off, after operative employee's working service finishes when guaranteeing to keep in repair, forces energized by change over switch, the examination lamp, and this reality is novel guarantees the fail safe of keeping in repair.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention is provided with high-voltage DC power supply, serial connection one group of switch 1 and one or more groups LED light fixture 2 on high-voltage DC power supply.
Be connected in parallel on the two ends of switch 1 and LED light fixture 2 after one group of high power relay 3 and travel switch 4 series connection, at the two ends of travel switch 4 change over switch 5 in parallel.
Claims (1)
1. the light fixture light cover is opened automatic power-off protection device; comprise high-voltage DC power supply; serial connection switch and LED light fixture on described high-voltage DC power supply; it is characterized in that being connected in parallel on after one group of high power relay and travel switch are connected the two ends of described switch and LED light fixture, at the two ends of described travel switch change over switch in parallel.
