Description

A kind of direct projection LED Grille lamp

[technical field]

The utility model relates to a kind of illuminating Grille lamp, relates to a kind of direct projection LED Grille lamp specifically.

[background technology]

Present illuminating Grille lamp structure comprises shell, reflection shield in the enclosure is set, be laid in light emitting source and starter device in the reflection shield, the light emitting source that Grille lamp adopted is a fluorescent tube on the market, the structure of fluorescent tube respectively adds a lamp holder by rectangular circular glass pipe two ends in the middle of being and constitutes, the two ends lamp holder of fluorescent lamp is the filament that there is a common heating at the two poles of the earth, these filaments are under the state of heat, can launch electronics, these electronics form electronic gas around filament, add in the fluorescent tube both sides and to compare higher voltage, form electric field, these electronics will be accelerated in fluorescent tube, are formed with the electron stream of certain speed (energy).What fluorescent tube the inside major part was filled is thin mercury vapour, and under the bright situation of fluorescent tube, these mercurys flash to gaseous state from liquid state, and mercury vapour is exactly the mercury atom under the free state.Electronics in the electron stream is beaten on mercury atom with certain speed, and mercury atom is excited, and becomes the mercury atom of excited state.The mercury of excited state has been spent the very short time and has just spontaneously been fallen back to original state, emits the light of some particular colors simultaneously, and this light is nature, can not be used for illumination.So the inwall of fluorescent tube has been coated with some fluorescent materials, penetrate down in the illumination of these particular colors, by the photon bombardment fluorescent material.After fluorescent material is excited, return original state, launch the light of comparison nature, be used for our normal lighting.The high-speed impact of fluorescent tube internal cause electronics and produce ultraviolet ray, luminous through the phosphor powder of glass tube walls, more common on the market fluorescent tube has general common fluorescent tube and gradually is the sunlight fluorescent tube of main flow, and both are compared to incandescent lamp bulb and have energy-conservation great advantage.But above design also exists a lot of defectives: 1, fluorescent tube needs the burning voltage power supply of a normal range (NR) that its starter is lighted; 2, service life shorter, through tradesman test, the theoretical value in fluorescent tube service life can only reach 10,000 hours; 3, because of fluorescent tube is to adopt glass tube to make, broken easily, be difficult for transportation; 4, fluorescent tube in manufacturing process because of in glass tube, being coated with fluorescent material and being filled with thin mercury vapour, mercury flashes to gaseous state from liquid state and is mercury atom under the free state, because of mercury is a kind of noxious material, discarded fluorescent tube is dealt with the environment that can influence periphery improperly, also brings disaster to biology and people's physical and mental health simultaneously.

[utility model content]

In order to overcome problems of the prior art, the purpose of this utility model is to provide a kind of energy-saving and environmental protection, is difficult for a kind of direct projection LED Grille lamp broken, that make things convenient for transportation, long service life and only need general voltage to light.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of direct projection LED Grille lamp, comprise shell, reflective groove in the enclosure is set and is arranged in the interior light emitting source of reflective groove, described light emitting source is the LED illuminator, described reflective groove comprises sidewall and diapire, the surface of reflective groove is provided with reflector layer, and described LED illuminator is fixed on the diapire of reflective groove.
