Abstract

The utility model provides a long service safety lamp, comprising a transparent and photic lamp body, a metallic lamp holder, a light emitting diode and a printed circuit board. The utility model is characterized in that a flexible circuit board which is provided with the light emitting diode is arranged along the inner wall or the outer wall of the lamp body; the shape of the flexible circuit board arranged in the lamp body corresponds to the shape of the lamp body. The utility model has the advantages that no heat is generated, no spark is produced, electric shock harm to human and animals can not be caused, the safety lamp can be continuously used for more than fifty thousand hours, the safety lamp is free from wind and weather, the safety lamp can not be oxidized, the power can be reduced to one watt, photoelectric conversion ratio is high, electricity is saved, the safety lamp can be formed into bulbs with various colors and various shapes according to actual demands, and the existing incandescent lamp can not compare with the safety lamp.

Description

A kind of long-life safety lamp

The utility model relates to a kind of lamp, and especially a kind of long service life and safe and reliable lamp comprise the shell of lamp and the lamp holder that is attached thereto.

Traditional bulb is because its shell is a glass shell, and be provided with luminous tungsten filament in the glass shell and be evacuated, in use not only will consume a large amount of electric energy sides makes the tungsten filament heating luminous, and tungsten filament easy burn-out, and can cause glass bulb blast and become the source of fire that therefore, existing bulb all exists service life short, power consumption, the frangible perishable deficiency that waits.For overcoming above-mentioned deficiency, someone has proposed a kind of scheme that replaces bulb with light emitting diode (being LED), as Chinese patent 99225376.4 disclosed " LED energy-saving lamp bubbles; it comprises printed circuit board (PCB), light emitting diode, lamp holder; it is characterized in that the corresponding light emitting diode that is equipped with of another side of printed circuit board (PCB); printed circuit board (PCB) is fixed in the hemispherical plastic casing; one of light emitting diode is housed faces up; hemispherical transparent lamp shade or arc-plane transparent lamp shade are fixedlyed connected with the hemispherical plastic casing, and the hemispherical plastic casing is provided with brass lamp holder outward.This bulb is can only single face luminous, and the side printed circuit board (PCB) that promptly only is provided with light emitting diode could be luminous, and another side does not then have light source, and range of application is restricted.

The purpose of this utility model is to overcome the deficiency of prior art, and a kind of long-life safety bulb that can change the illuminating part shape with the lamp housing change of shape is provided, and makes this bulb make various obform bodies such as hemisphere, spherosome, elongated cylinder, square body, triangle body.

Concrete scheme of the present utility model is: it comprises transparent printing opacity lamp housing, metallic lamp holder, light emitting diode, printed circuit board (PCB), it is characterized in which is provided with the flexible PCB of light emitting diode along envelope inner wall or outer wall setting, and the shape of flexible PCB and lamp housing shape adapt, so as the shape of flexible PCB with the variation of lamp housing shape respective change.Light emitting diode on the described flexible PCB is arranged on the single or double of flexible PCB, and light emitting diode be arranged as dot matrix, some face formula, crisscross formula etc.Described lamp housing is shaped as spheroidal, perhaps cambered surface sphere, perhaps conical surface sphere, perhaps cylindrical, the square column type of vertical bar, triangle cylindricality, perhaps cylindrical, the square column type of knee, triangle.

Because such scheme makes the utility model compared with prior art have following advantage and effect:

1, security: this bulb is a cold light source, need not place vacuum or inert gas, and it does not generate heat, and does not produce electric spark, and its lead is a DC low-voltage, can not cause the harm of getting an electric shock to people and animals.

2, longevity: this bulb can use more than 50,000 hours incessantly, and is interrupted and lights (as flicker) and do not influence its service life, and other is not afraid of wind and weather, can oxidation.

3, applicability: this bulb installs supply unit additional, but AC/DC is not subjected to the influence of voltage, current fluctuation.Do not need in addition conventional safeties, can realize automatic protection, but but also slow fire of light direct projection can initiatively send various colouramas such as red, green, white, champac as required, and power can be little of 1 watt.

4, because this bulb can be electric energy loss on heating wire, thus the photoelectric conversion rate height, power saving.

5, various informative: as can to change with the variation of bulb shell shape owing to which is provided with the shape of the flexible PCB of light emitting diode, therefore, can form the bulb of various colors, various forms according to actual needs, and available circuit control or manual remote control control automatically.

The utility model can extensively be used in the place that fire easily takes place for all kinds of warehouses, bar, cinema, wood-working factory, chemical plant etc., also can be used for the place that requirements such as highway, railway, civil aviaton's point duty are lighted continuously, and outdoor locations such as city light engineering, advertisement, lamp box, and the lead of being with people and animals are got an electric shock, light is dazzlingly beautiful, durable, lamp housing moulding uniqueness is that existing incandescent lamp can't be comparable.
