Abstract
The utility model relates to an electric lamp with buffering current, which comprises a bulb, a capacitor and a relay; a buffering and voltage reducing device is connected in parallel with a power supply circuit of the bulb, and the buffering and voltage reducing device consists of the capacitor and the relay which are connected in series. The electric lamp with buffering current has a simple structure, can effectively protect the bulb against damage caused by instable power supply voltage, and prolongs the service life of the bulb.
Description
Technical field
The utility model relates to a kind of lighting lamp, especially a kind of electric light that has buffer current.
Background technology
In use because power supply raises or lights the moment influence that is hit, the easy burn-out bulb influences people's use to electric light.
The utility model content
In order to solve the problem that electric light in use runs into, the utility model proposes a kind of electric light that has buffer current, this simple construction can effectively prevent the injury of supply voltage shakiness to bulb, has prolonged the useful life of bulb.
The technical scheme that its technical problem that solves the utility model adopts is: this electric light that has buffer current comprises bulb, electric capacity and relay; Be parallel with a buffering dropping equipment on the current supply circuit of this bulb, this dropping equipment is electric capacity and relay series connection.
The beneficial effects of the utility model are: this has the simple construction of buffer current, can effectively prevent the injury of supply voltage shakiness to bulb, has prolonged the useful life of bulb.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing 1 has the operation principle schematic diagram of the electric light of buffer current for this.
Among the figure, 1. bulb, 2. electric capacity, 3. relay.
Embodiment
In accompanying drawing 1, this electric light that has buffer current comprises bulb 1, electric capacity 2 and relay 3; Be parallel with a buffering dropping equipment on the current supply circuit of this bulb 1, this dropping equipment is electric capacity 2 and relay 3 series connection.
When bulb 1 was lighted, electric capacity 2 can absorb humorous subwave, prevents that effectively bulb 1 from burning out, and reached the purpose of step-down in the process of using, thereby prolonged 1 useful life of bulb.
