Abstract

The utility model discloses a household LED bulb, which comprises a lamp holder and a transparent lamp housing connected onto the lamp holder. A plurality of LED light emitting diodes and a circuit component are arranged in the lamp housing, a reflecting disc located above the circuit component is arranged in the lamp housing, a metal coating is disposed on the surface of the reflecting disc, and the LED light emitting diodes are distributed on a plurality of concentric circles around the reflecting disc. As the metal coating is arranged on the surface of the reflecting disc and the LED light emitting diodes on the reflecting disc are in concentric circle distribution, when the LED light emitting diodes are illuminated, light is projected through the transparent lamp housing, and finally, light spots of the bulb are in the shape of overlapped rings, uniformity of the light spots is higher than 80%, and illumination effect of the bulb is the best.

Description

A kind of household LED bulb
Technical field
The utility model relates to a kind of lighting, particularly a kind of improvement of household LED bulb.
Background technology
Furniture lighting in the past is generally incandescent lamp bulb or fluorescent tube, and these two kinds of light fixture caloric values are big, and the life-span is short.LED is as a kind of emerging semiconductor light-emitting elements, have that volume is little, power consumption less, long characteristics of life-span, be widely used in various lighting fields, but the hot spot of present LED bulb projection is even inadequately mostly, cause color effect bad, practicality has much room for improvement.
The utility model content
The purpose of this utility model provides the LED bulb that a kind of hot spot is even, color effect is good.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of household LED bulb, comprise lamp holder and be connected transparent lamp case on the lamp holder, be provided with LED light emitting diode and circuit unit in the lamp housing, be provided with the optical reflective disk that is positioned at the circuit unit top in the described lamp housing, the optical reflective disk surface is provided with the coat of metal, described LED light emitting diode has a plurality of, and being distributed as with the optical reflective disk center is a plurality of concentric circles in the center of circle.
Described lamp holder end is a spirality, and circuit unit is fixed by packaging plastic and lamp holder.
The beneficial effects of the utility model are: the optical reflective disk surface is provided with the coat of metal, and the LED light emitting diode on the optical reflective disk is the concentric circles distribution, light throws away by transparent lamp housing when luminous, the light spot shape of final bulb is the circular of stack, the uniformity of hot spot reaches more than 80%, makes the illuminating effect of bulb reach best.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
With reference to shown in Figure 1, a kind of household LED bulb, comprise lamp holder 1 and be connected transparent lamp case 3 on the lamp holder 1, be provided with LED light emitting diode 4 and circuit unit 5 in the lamp housing 3, be provided with the optical reflective disk 2 that is positioned at circuit unit 5 tops in the described lamp housing 3, optical reflective disk 2 surfaces are provided with the coat of metal, described LED light emitting diode 4 has a plurality of, being distributed in optical reflective disk 2 centers is on a plurality of concentric circles in the center of circle, described lamp holder 1 end is a spirality, circuit unit 5 is fixed by packaging plastic and lamp holder 1, because optical reflective disk 2 surfaces are provided with the coat of metal, and the LED light emitting diode 4 on the optical reflective disk 2 is the concentric circles distribution, light throws away by transparent lamp housing 3 when luminous, the light spot shape of final bulb is the circular of stack, and the uniformity of hot spot reaches more than 80%, makes the illuminating effect of bulb reach best.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
