The specific embodiment

For further setting forth the utility model LED energy-saving lighting lamp, do more detailed explanation below in conjunction with embodiment.

LED is a kind of efficient light-emitting device, and the light colour temperature that its white pipe sends is extremely near daylight.But single luminous tube only needs very low voltage to drive, and can only supply with direct current.

220 alternating currents are all adopted in the illumination of our common usefulness etc.If adopt the scheme (complicated power converting circuit) of power saving fluorescent lamp, can increase the cost of illuminating lamp obviously.

The utility model adopts capacitance decompression, luminous tube connection in series-parallel to use, and realizes the 220V Alternating Current Power Supply, makes a kind of domestic lighting lamp.

Its physical circuit is seen Fig. 5.Two

luminous tube strings

41,42 are formed in several LED luminous tube 4 same polarity connection in series-parallel, can have only the luminous tube of a string polyphone in each luminous tube string, and the luminous tube of several strings polyphones also can be arranged, and what of quantity are decided according to required illumination intensity.

Connect with the reduction voltage circuit 5 that composes in parallel by electric capacity 43 and resistance 44 after two

luminous tube string

41,42 reversed polarity parallel connections.How many sizes of electric capacity decides according to luminous tube, can calculate by the capacitive reactance formula of electric capacity.Be protection luminous tube 4, can be on the

luminous tube string

41,42 of parallel connection a piezo-resistance 45 in parallel.Capacitance decompression is kind of the simplest reduction voltage circuit, is applicable to the circuit of non-induction reactance, non-capacitive reactance, just in time is applicable to luminous tube; The greatest problem of capacitance decompression is to have high-tension electricity on the circuit, as bulb, itself is exactly an independent object, just can use as long as carry out the insulation of lamp body, and the insulation of lamp body is more cinch.

The profile of the utility model LED energy-saving lighting lamp and concrete structure can be diversified, and two embodiment are provided here.

First bulb-shaped; see Fig. 1 and Fig. 2; reflector 3 with some luminous pores is arranged in back taper housing 1; the inwall of back taper housing 1 also can plate reflector layer; a wiring board 2 is adorned in reflector 3 back, and the LED luminous tube 4 and the reduction voltage circuit 5 that is contained in another side of same quantity is equipped with in the position corresponding with the hole on the reflector 3 on the wiring board 2, and the head of LED luminous tube 4 part from the hole of reflector 3 is stretched out; housing 1 oral area has dull and stereotyped transparent protective shield 6, and afterbody has screw holder 7.Luminous tube 4 is connected by Copper Foil on wiring board 2 with reduction voltage circuit 5, has two to exchange links on the wiring board 2, connects respectively to wait a shell and a central contact of 7.This form can directly be replaced ordinary incandescent lamp.
