Abstract

The utility model relates to an astigmatic LED (light emitting diode) bean gall lamp which comprises a radiator, a power supply interface and a lamp body; the astigmatic LED bean gall lamp also comprises a plurality of LED luminous bodies, an LED chip connected with the radiator and an arc-shaped transparent lampshade for diverging light, wherein the LED luminous bodies are all arranged on the LED chip. In the astigmatic LED bean gall lamp provided by the utility model, the LED chip serves as a light source and the arc-shaped transparent lampshade which can play an astigmatic function covers the chip, so that light rays emitted from the LED chip can be sent out through an optical lens, dizzy shadows and light spots generated by multiple LED light sources can be eliminated, the luminous efficiency can be clearer, meanwhile, the light rays can be sent out through the lens, thus the light rays can be diffused and the lamination range can be increased.

Description

Astigmatism LED bean container lamp

Technical field

The utility model relates to LED lighting apparatus field, particularly a kind of effective astigmatism, the astigmatic LED bean container lamp that illumination zone is big.

Background technology

Bean container lamp should be that of Grating jetting lamp is commonly called as usually, because profile similar " bucket " shape of the light source that the light fixture inner bag uses (old times are measured the utensil of grain) so be the lamp of making bold, because of the cause of partials, also is bean container lamp.Bean container lamp is fit to be installed in the office room of furred ceiling, and it is divided into two kinds of embedded and ceiling types.Astigmatism LED bean container lamp is with the bean container lamp of LED as spot light, led light source have use low-tension supply, power consumption less, strong, the stable height of applicability, response time weak point, environmentally safe, multicolor luminous etc. advantage., be the third generation energy-saving illumination light source after incandescent lamp, three-color fluorescent lamp, thereby be widely used in lighting field as lighting source with LED.The existing suitable astigmatic LED bean container lamp of illumination on a large scale all is to use a plurality of LED point light source light-emitting illuminations, can produce ghost image, dazzle shadow but multiple spot is luminous; Light efficiency is fuzzy; People work under this light, and eyes are easy to fatigue, and eyes are also had certain injury.

Therefore, how to overcome astigmatic LED bean container lamp and can produce ghost image when luminous, the shortcoming of dazzle shadow etc. is the technical problem that needs to be resolved hurrily in the industry.

Summary of the invention

The main purpose of the utility model provides a kind of suitable astigmatic LED bean container lamp of illumination on a large scale, is intended to improve the astigmatic effect and the lighting quality of astigmatic LED bean container lamp, and its illumination zone is strengthened, and when luminous free from glare shadow and hot spot.

The utility model proposes a kind of astigmatic LED bean container lamp; Comprise radiator, power interface and lamp body; Also comprise the led chip that several LED illuminators, are connected with said radiator and the arc Transparent lamp shade of a diverging light, said LED illuminator is installed on the said led chip.

Preferably, said arc Transparent lamp shade is the optical lens that diverging light is used.

Preferably, said arc Transparent lamp shade is that high borosilicate material is processed, and high borosilicate is the specific glass material of a kind of low thermal expansion, high temperature resistant, high strength, high transmission rate and high chemical stability; Be used in the said astigmatic LED bean container lamp as optical lens with this material, because its ultralow expansion rate, when the LED luminance temperature raises; The form variations of optical lens is very little; Make its effect highly stable, improve astigmatic effect, increase illumination zone light; And its light transmittance is very high, and brightness of illumination is increased greatly.

Preferably, the embedded and said lamp body of said radiator employing screw thread is connected fixing.

The utility model with led chip as light source; And on led chip, cover the arc Transparent lamp shade of astigmatism effect together, and the light that sends on the led chip is distributed through this optical lens, eliminated dazzle shadow and hot spot because of the luminous generation of a plurality of led light sources; Make light efficiency more clear; And distribute by lens, make divergence of beam, increase illumination zone.

Description of drawings

Fig. 1 is the example structure sketch map of the utility model astigmatism LED bean container lamp.

The realization of the utility model purpose, functional characteristics and advantage will combine embodiment, further specify with reference to accompanying drawing.

The specific embodiment

Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

With reference to Fig. 1; One embodiment of the astigmatic LED bean container lamp of the utility model is proposed; This astigmatism LED bean container lamp comprises radiator 1, power interface, lamp body 4, metal back cover 3 and several LED illuminators 7, also comprises the arc Transparent lamp shade 8 of a led chip 6 and a diverging light.Said power interface is arranged on the bottom of said lamp body 4, and the bottom of lamp body 4 is provided with screw thread 5, in the said lamp body 4 one drive circuit is housed, and drive circuit is connected with power line and said led chip 6 respectively, and said led chip 6 is installed in the upper section of said lamp body 4.It is fixing that said radiator 1 adopts the embedded and said lamp body of screw thread to be connected; The bottom of said radiator 1 and said metal back cover 3 all be provided with one supply the interior cross section of circular hole 2, two circular holes 2 that the bottom of said lamp body 4 passes through be provided with said bottom on screw thread 5 respective threads, said metal back cover 3 is installed in the centre of said lamp body 4 and said radiator 1; Pass through rotation between said lamp body 4 and metal back cover 3 and the radiator 1 with tightening mutually between the screw thread; Interfix, the heat accumulation that led chip 6 produces when luminous in lamp body 4, by lamp body 4 with heat transferred radiator 1; Exhale; The temperature constant that makes led chip 6 reduces the light decay of LED at a relatively low temperature value, prolongs the service life of LED.

Said LED illuminator 7 equal dot matrix are arranged on the said led chip 6, can increase and reduce the number of said LED illuminator 7 along with the needs of illumination brightness.Said arc Transparent lamp shade 8 covers on the outside of said led chip 6.Said arc Transparent lamp shade 8 is the astigmatic together optical lens that acts on.Said optical lens is the optical lens of high borosilicate material, and high borosilicate is the specific glass material of a kind of low thermal expansion, high temperature resistant, high strength, high transmission rate and high chemical stability, is used in the said astigmatic LED bean container lamp as optical lens with this material; Because its ultralow expansion rate; When the LED luminance temperature raise, the form variations of optical lens was very little, makes its effect to light highly stable; Improve astigmatic effect, increase illumination zone; And its light transmittance is very high, and brightness of illumination is increased greatly.With led chip 6 as light source; And the arc Transparent lamp shade 8 of cover one astigmatism effect on led chip 6, the light that sends on the led chip 6 is distributed through this optical lens, eliminated dazzle shadow and hot spot because of the luminous generation of a plurality of led light sources; Make light efficiency more clear; And distribute by lens, make divergence of beam, increase illumination zone.
