Abstract
A light source with internal light distribution curves comprises a glass shell with a reflective coating, a burner, a stem and a light emitter, wherein the area of the reflective coating is smaller than that of a transmission area; the distance H between the edge of the reflective coating and the center of the transmission area is 1/2 to 1/3 of the maximal radius R of the glass shell; the upper surface of the glass shell is a regular wave-shaped cambered surface; the reflective coating is matched with the upper surface of the glass shell in shape; the light emitter is an ionoluminescence ball. The shape of a traditional glass shell is changed, the internal light distribution curves are dual-wing setting-out curves, the angle is larger than 120 degrees, related large-sized luminaire is not required, the reflectivity of the light source is improved to 98%, the light extraction efficiency is larger than 92%, the system light efficiency is higher than 110-160 lumens per watt, the illumination and the light distribution are more uniform, chord light interference is reduced, the GB 50034-2004 and the CJJ45-2006 'Urban Road Lighting Design Standard' of the Ministry of Construction are met, the waterproof and dustproof grade meet the above IP65 demand, the service life of the light source is prolonged, the intensity and the irradiation effect of the light source are improved, and the purposes of energy saving, low price and convenience in use are achieved.
Description
Technical field
The utility model relates to a kind of lighting source, and particularly a kind of have a reflection function long service life, suitable a kind of light source containing interior light distribution curve of installing and using in places such as arterial traffic, trade, engineering construction, tunnel, agriculture factories.
Background technology
Now high-intensity gas discharge lamp, LED light source are widely used in road, square, agriculture factory etc. and need a large amount of daylighting, the high occasion of brightness, for reaching illuminance uniformity and improving the object of light utilization efficiency, they also need to configure reflector beyond light source, electric appliance box, trigger, driving power, with the light fixtures such as shell of heat dissipation type, use.
The erosion of reflector light fixture vulnerable to pollution, oxidation, accumulation dust and rainwater that cause is joined outward, use after a period of time, the effective rate of utilization of light declines greatly, in the term of validity of light source life, reflection efficiency is only 85%～50%, Luminaire efficiency is 76～45%, system light efficiency is at 100～35 stream transparent tiles, and whole light fixture volume is large, heavy weight, energy consumption is high, metal material consumption is large.
It adopts plate armature mostly LED light source, the uniformity, the brightness that impinge upon on road surface are all poor, its heat radiation is slow, light decay is large, cutoff angle degree is little, also can cause zebra effect, and it is serious to dazzle wide light pollution, directly driver's sight line is disturbed in impact, dazzling especially, also need to increase the light fixture of heat radiation, so it is expensive.
The patent No. 03277620.9 " gas discharge bulb ", though a kind of inner reflective lamp bulb is provided, with speculum, as reflecting layer, be arranged on the bulb using in glass bulb, he only focuses on electric arc tube for reducing reverberation, make electric arc tube reduce exposure intensity, reduce heating, thereby increase the service life.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of light source containing interior light distribution curve is provided, not only volume is little, deal is light, maintenance cost is low, low price, adopt internal reflection layer structure not need huge light fixture supporting, light source points to clear and definite, open and flat of light distribution curve is large, and light reflectivity is high, uniform-illumination.
The technical scheme in the invention for solving the above technical problem is: a kind of light source containing interior light distribution curve, comprise glass bulb, lamp holder, stem stem, illuminator with reflectance coating, described reflectance coating area is less than transmission area area, reflectance coating edge is to transmission area centre distance H=1/2～1/3R glass bulb maximum radius, described glass bulb upper surface is well-regulated wave cambered surface, described reflectance coating and glass bulb upper surface shape match, and described illuminator is ionoluminescence ball.
Compared with prior art, the utility model has the advantage of: this changes the shape of traditional glass bulb containing the light source of interior light distribution curve, and upper surface is well-regulated wave cambered surface.Interior light distribution curve is that double-vane is open and flat, angle is greater than 120 degree, each angle reflection light scatters above ionoluminescence ball is not concentrated in, therefore there is not ionoluminescence ball fever phenomenon, because glass bulb is two-way arcuate structure in length and breadth, the light that ionoluminescence ball sends transmits after arc glass bulb, be irradiated to more equably the place of sensing, next light will be reflected by top again simultaneously, again through glass bulb, be transmitted to illumination to picture downwards, do not need huge die casting light fixture supporting, just make light source reflectivity bring up to 98%, light extraction efficiency is greater than 92%, system light efficiency is greater than 110～160 stream transparent tiles, illumination, light distributes and more evenly reduces again the interference of string light, while now using, add a baffle plate thereon, the object only not fallen down above for protection light source smashes the effect of destruction.This light source reaches the CJJ45-2006 of Ministry of Construction Lighting Design of Urban Road standard, and GB50034-2004 national standard, water proof and dust proof grade reaches requirement more than IP65, has improved light source life, the intensity of light source, radiation response, reaches energy-conserving and environment-protective, low price, object easy to use.

The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Illuminator adopts ionoluminescence ball 3.
Lamp holder is screw socket 10 or the ceramics seat 6 that is fixed with two Metallic rod 7.
Inner surface at glass bulb 1 wave cambered surface place, spraying one deck reflectance coating, be that reflectance coating 2 matches with glass bulb 1 upper surface shape, reflectance coating 2 areas are much smaller than light source transmission area area, and reflectance coating edge is to the maximum radius of transmission area centre distance H=1/2～1/3R glass bulb.
One end of support bar 4 is fixedly connected on pillar 8, the other end is connected on one end of lamp holder stem stem 5, the spot welding sheet 9 of fixedly cooling down also on it, stem stem 5 is connected with ionoluminescence ball 3, the other end of glass bulb 1 inserts in ceramics seat 6 and is cementingly fixed into whole lamp holder, on ceramics seat 6, fix one end of two Metallic rod 7, one end of two Metallic rod is also connected with the other end of stem stem, as shown in Figure 2.
During use, two Metallic rod 7 on ceramics seat 6 are inserted in power socket and just can be used (figure does not draw).Lighted after ionoluminescence ball 3, light is irradiated to and points to place through transmission area and wave cambered surface, the light simultaneously being come by the reflection of top wave cambered surface, downwards from transmission area through glass bulb directive lighting object, greatly improved light efficiency, also increase the service life.
Only holder structure is different from the first scheme for alternative plan, and screw socket 10 is prior art.
