Description
Technical field
The utility model relates to the electric lighting technical field, particularly a kind of LED illuminating lamp.
Background technology
At present, common energy-saving lamp is under low-pressure state, though can start, the illumination instability burns out easily, and illuminance is low, really can not play energy-saving and environmental protection, causes many economic losses to the user.As Chinese patent application number is 200710143281.6, the applying date is on August 9th, 2007, denomination of invention is a kind of LED electricity-saving lamp, it is characterized in that: comprise housing, comprise automatic controller and a plurality of LED lamp in the housing, the LED lamp adopts and is connected in parallel, and an end of automatic controller connects power supply, and the other end links to each other with LED lamp parallel circuit.This patent structure is easy for installation, is convenient to change the LED lamp, is adapted at that public place or family etc. are local to be used, and its shortcoming is to cause the electricity-saving lamp job insecurity easily under the state of undertension, has a strong impact on its service life.
Summary of the invention
The purpose of this utility model is exactly that a kind of not only environmental protection and energy saving, the stability that provide for the deficiency that solves prior art are high, the life-span is long, and is applicable to the environmental protection and energy saving LED illuminating lamp in the area of undertension.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of environmental protection and energy saving LED illuminating lamp; a plurality of LED lamp group, the automatic controllers that are connected in parallel that comprise lamp body and interior setting thereof; be provided with bridge rectifier in this automatic controller and connect power supply; it is characterized in that: an ac input end of described bridge rectifier is provided with the step-down holding circuit of mainly being made up of electric capacity and resistance; the output of bridge rectifier is connected with the main pressure regulator circuit, and the input of LED lamp group is provided with current-limiting resistance and is connected in series with it.
As further specifying of such scheme, the output of described bridge rectifier is provided with filter capacitor, and the main pressure regulator circuit is connected in parallel with it.
Electric capacity in the described step-down holding circuit is in parallel with resistance, and the input of this resistance connects power supply.
Described main pressure regulator circuit comprises a resistance that is connected in parallel with LED lamp group.
Described every group of LED lamp end all is serially connected with current-limiting resistance, and LED lamp group comprises several mutual LED coupled in series lamps.
Described lamp body adopts plastic casing.
The operating current of described LED lamp is 15mA～20mA.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
1, the utility model adopts at an ac input end of the general bridge rectifier that connects the LED lamp and sets up a decompression capacitor and protective resistance; it is in parallel with filter capacitor that the output of bridge rectifier is provided with a main pressure regulator resistance; the LED lamp is unlikely to be burnt out in order to protect; other establishes resistance string and is connected to its current limliting hypotensive effect of LED lamp end; make under low pressure and the high pressure conditions and all can normally start illumination, applied range.
2, LED lamp packet chain and combined circuit have solved in single serializer circuit and have damaged the problem that whole lamp does not work that causes as the LED lamp.
3, resistance control is flowed through the electric current of LED lamp between 15mA to 20mA, the LED illuminating lamp of an energy consumption 5W, and its brightness is equivalent to the common energy-saving lamp of 18W, is equivalent to the incandescent lamp bulb of 60W, and it is to real energy-conservation effect; And because the electric current of the LED that flows through, has increased the service life of LED lamp illumination less than 20mA, the life-span of continuous illumination reached more than 8000----200000 hour.
4, owing to adopt brand-new environmentally-friendly plastic shell, solved traditional glassware, fallen on the ground the problem of breaking, and can reclaim Recycling, than now in the three more environmental protection of basic T5 illuminating lamp of being supplied on the market, more energy-conservation.
