Description

AC LED bulb lamp

Technical field

The utility model relates to LED bulb, especially relates to a kind of AC LED bulb lamp.

Background technology

At present, the continuous introduction and implementation of the policy of energy-saving and emission-reduction both at home and abroad, delisting timetable listed by incandescent lamp, and LED semiconductor lighting under this background technological progress quickly, progressively by market is accepted, applies scale increasing.

In existing LED lighting apparatus, mostly adopt the Switching Power Supply constant-current drive technology of comparative maturity, its advantage is that operating current is stablized, actuation techniques comparative maturity.But have some obvious shortcomings, the reliability of driver is not very high yet, and the life-span is general all lower than the life-span of LED light source.

Summary of the invention

The purpose of this utility model is to provide one to drive without Switching Power Supply, directly can use the electrically driven (operated) AC LED bulb lamp of interchange, and it has, and cost is low, volume is little, photoelectric transformation efficiency is high, the advantage of electromagnetic-radiation-free.

The purpose of this utility model is achieved in that

A kind of AC LED bulb lamp, comprise lampshade, alternating current LED light source module plate, heat-conducting plastic radiator, lamp holder and wire, lampshade is fixed on heat-conducting plastic radiator by bayonet socket or the mode of playing glue, alternating current LED light source module plate is fixed by screws on heat-conducting plastic radiator, heat-conducting plastic radiator and lamp holder are together by a threaded connection, the electrode that two connect the electric main of 110V or 220V is provided with on lamp holder, feature is: in heat-conducting plastic radiator top boss on be fixed with circular alternating current LED light source module plate, alternating current LED light source module plate is evenly welded by series connection or in parallel or go here and there and some AC LED wicks combining of the mode combined, and be wired on two electrodes of lamp holder.

The phosphor powder layer that one deck has light-decay characteristic is coated with at the inner surface of lampshade.

Phosphor powder layer is the yellow fluorescent powder that blue-ray LED excites, or the mixture of the blue light to excite for purple LED and yellow fluorescent powder, or the mixture of the redgreenblue fluorescent material to excite for ultraviolet leds, phosphor powder layer composition can be YAG, silicate or nitrogen oxide.

AC LED wick is the one exchanging blue-ray LED, exchange purple LED or exchange in ultraviolet leds.

In order to ensure safety, there is the protective casing of heat-resistant antifriction at wire overcoat.

The heat that alternating current LED light source module plate sends can be exhaled by heat-conducting plastic radiator in time.

Lampshade is made up of transparent PC, acrylic or glass.

Alternating current LED light source module plate adopts the good material of heat conduction to make, and can be metal, pottery or copper foil material.

The utility model due in heat-conducting plastic radiator top boss on be fixed with circular AC LED light source module plate, alternating current LED light source module plate has evenly been welded some AC LED wicks, and be wired on two electrodes of lamp holder, like this by the electric main of supply 110V or 220V, just can light the AC LED wick on AC-operated light sources module, photoluminescent phosphor layer on the optical excitation lampshade that AC LED wick produces, the light that AC LED wick produces and the light that fluorescent material sends form white light after mixed light, afterglowing material simultaneously on lampshade has the high after-glow brightness of more than 20ms, ensure under the frequency of 50HZ or 60HZ, the luminosity of intermittent time can be made up, eliminate stroboscopic effect, obtain stable white light.

The beneficial effects of the utility model are: abandoned and adopted the life-span compared with short, that volume large, cost is higher Switching Power Supply driving method, direct employing AC LED wick and phosphor powder layer, directly light under 220V or 110V alternating voltage, fluorescent material has the high after-glow brightness of more than 20ms simultaneously, when ensureing to work under the AC power being not less than 50HZ, the luminosity of intermittent time can be made up, eliminate stroboscopic effect, obtain stable white light.
