Abstract

The invention relates to the illumination field, in particular to an energy-saving illuminating lamp for replacing a traditional fluorescent tube and using an LED together with a glass light guide tube to realize light uniformity. The lamp adopts the structure that two single white LED light sources are arranged at two ends of a solid glass bar with the length of 150-300 mm and the diameter of 7-10 mm respectively. The glass bar is formed by directly stretching glass in a softening state after being heated, and is smooth in surface. Two ends of the glass bar are smooth, and are polished. 1/2 side surfaces of the glass bar are bonded with metal reflective films. When the LED is lightened, light is conducted to the glass bar through two ends; as a plurality of reflections are generated in the glass bar through the light guide effect, the light is uniform in the glass bar and is evenly reflected to areas needing illuminators through the metal reflective films.

Description

Energy-saving LED grass tube lamp

Technical field

The present invention relates to lighting field, is a kind of electricity-saving lamp of light Uniform Illumination of realizing in conjunction with grass tube with LED.

Background technology

Civil illuminating lamp great majority are in the market used incandescent lamp bulb, and fluorescent tube and electricity-saving lamp (compact fluorescent lamp) are as principal light source.The luminous efficiency of incandescent lamp is minimum, colour temperature is partially yellow, the life-span is short.For energy-conservation consideration, country will ban incandescent lighting within several years.Fluorescent tube and the electricity-saving lamp luminous efficiency of comparing with incandescent lamp is high, but colour temperature is generally colder.Operation principle due to ballast during illumination can produce flicker, and human eye health is had to certain harm.The shortcoming of fluorescent tube and electricity-saving lamp maximum is to contain mercury in addition, if discarded fluorescent tube is dealt with improperly environmental hazard very large.The LED lamp has luminous efficiency high as novel lighting source, and volume is little, and it is various that colour temperature is selected, and the life-span is long, flicker free, the multiple advantage such as pollution-free .the light efficiency of ordinary incandescent lamp is 121m/W, life-span is less than 2000 hours, the light efficiency of spiral energy-saving lamp is 60lm/W, life-span is less than 8000 hours, the T5 fluorescent lamp is 96lm/W, life-span is approximately 10000 hours, and the white light LEDs light efficiency that diameter is 5 millimeters can surpass 150lm/W in theory, and the life-span can be greater than 100000 hours.Nowadays the Household LED illumination lamp occurred on market, adopts the plurality of LEDs composition lighting unit of single LEDs or dense arrangement luminous more, and illuminating effect and spot light are similar.。The LED lamp that has the illumination uniformity of fluorescent tube does not also emerge.

Summary of the invention

The present invention adopts White LED as light source, the Novel lighting lamp of light evenly being dispersed by the grass tube with reflective membrane.The problem solved is, lighting evenly, do not glimmer, safeguard human eye health.Be applicable to the illuminations such as desk lamp, office, reading room, classroom.The structure of this lamp: in length, be 150 ~ 300mm, a single White LED is respectively installed at the two ends of the real core rod that diameter is 7 ~ 10mm.Grass tube is directly to stretch and form under glass heats after-tack state, any surface finish.The two ends of glass bar are smooth, and, through polishing, when light is entered, loss is little.Reflective metal film is pasted in 1/2 side of glass bar.When LED lights, light conducts to glass bar by two ends, produces Multi reflection in glass bar due to photoconductive effect, so light is very even in glass bar.Reflectance coating in the glass bar side is concentrated light and is reflexed to opposite side, in same direction, increases brightness of illumination.These have, and the life-span is long, and light efficiency is high, throw light on evenly soft, and the advantage of flicker free.

The accompanying drawing explanation

The detail perspective view that Fig. 1 is fluorescent tube one end;

The figure that blocks that Fig. 2 is the fluorescent tube whole structure.

The specific embodiment

A kind of novel energy-saving LED grass tube lamp, be comprised of clear glass conduit, high-power White LED, sleeve.Wherein grass tube is to be drawn and formed by bigbore glass bar fusing, and needs end face smooth, through overdoing, throws and the grinding and polishing processing; The length of grass tube is at 150 ~ 300mm, and diameter range is 7 ~ 10mm; Grass tube one side is vertically pasted the reflective aluminum film.High-power White LED need to be arranged in sleeve and form an integral body with grass tube; According to the length of grass tube, for reaching good illuminating effect, need to select LED according to following rule: when light pipe length is less than 15mm, single LEDs power should be at 1W between 2W; When light pipe length, during at 150mm ~ 300mm, single LEDs power should be 2W between 4W; The installation of LED must be close to the end face of grass tube, is positioned at the center of grass tube.When electric current is switched on to LED by pin, White LED institute isolychn incides grass tube like this, propagates in conduit and is concentrated and reflex to the zone that needs illumination by the aluminium film of a side, strengthens illuminating effect.
