Abstract
The utility model provides a novel LED (light emitting diode) down lamp. The LED down lamp comprises a cylindrical lamp shade and a flat diffusion plate which is connected to the cylindrical lamp shade, wherein an LED lamp bead is arranged in the cylindrical lamp shade; an MCPET (micro cellular polyethylene terephthalate) reflection plate is arranged in the lamp; and a fin type radiator is tightly adhered on an LED circuit board. The LED down lamp has the advantages of excellent illuminant and driving heat resistance performances, compact structure, attractive appearance and the like.
Description
Technical field
The utility model relates to LED Down lamp mechanism design technology, especially relates to a kind of LED Down lamp back radiator structure and the outer cylindrical lampshade outward appearance of novelty and the application layout of reflectorized material, improves the heat dispersion and the luminescent properties of Down lamp.Use E27 screw type lamp holder, user installation is easy to use.
Background technology
The tradition Down lamp adopts Halogen lamp LED more, and luminous efficiency is lower, relatively power consumption, illuminated environment temperature are risen, service life is short.
Yet along with the develop rapidly of current LED industry, the status of conventional light source has received greatly challenge, and the appearance of LED Down lamp is wherein just arranged, and in development at full speed.Advocating green illumination, the world today of energy savings, the LED Down lamp is with the obvious advantage, and comparing the conventional cartridge Lantern Festival can be about 60%, and the life-span reaches 50,000 hours especially, and the drive circuit module reliability is stronger.The LED Down lamp adopts the LED light emitting module to add that radiator adds that the pattern of drive circuit module substitutes the tactic pattern of traditional Down lamp.
The more traditional Down lamp price of LED Down lamp in the market is high; Also being popularized, is the illuminating industry inevitable development trend but following its replaces traditional Down lamp, because Future Society energy problem is more and more serious; Increasingly high to requirement on environmental protection; And the LED Down lamp just meets the requirements, and it is than the energy-conserving and environment-protective more of traditional Down lamp, and the life-span is longer.
But because the factor of this body structure of LED, make light fixture produce the dazzle and the brightness irregularities phenomenon of degree varies after completing, defectives such as the too high and albedo deficiency of specular reflectivity further promote to have received restriction for it.
The utility model content
The utility model is to above-mentioned defective, and purpose is to provide a kind of LED Down lamp that has high efficiency luminous efficiency, has good exposure intensity and uniformity of luminance.
The technical scheme that the utility model adopts is: comprise the tubular lampshade and be connected the planar diffusion plate on the tubular lampshade, be provided with LED lamp pearl in the tubular lampshade, be provided with the MCPET reflecting plate in the lamp interior space.
LED lamp pearl and aluminum-based circuit board welding, aluminum-based circuit board and fin type radiator fit tightly, and coating heat-conducting silicone grease between the two makes the conduction of its heat not have tomography.
The utlity model has following advantage: 1) the utility model adopts novel trans luminescent material and planar diffusion plate to improve light efficiency, the evenly distribution of light, and more traditional Down lamp uses reflector to carry out lighting angle and uniformity control has superiority better effects if more.Reflectorized material MCPET is that the English of Micro Cellular PET Sheet is write a Chinese character in simplified form.It adopts PET (polyethylene Terephthalate) is base material, through the HTHP foaming treatment, obtains the bubble of 10 micron levels, forms reflecting plate by hundreds of millions of micro bubbles.Application in the LED light fixture; For the luminous efficiency that promotes light fixture; There is good lifting dazzle processing aspect and improves because the excellent characteristic of MCPET material; Therefore homogeneity can both be kept for the albedo of each wavelength light source, under the situation that loyal reflection original light source requirements is arranged, more its speciality can be brought into play.Add the application of planar diffusion plate, effectively improve light intensity brightness value 8%, evenly the distribution of light; 2) further the utlity model has good performance of heat dissipation in order to make, the utility model carries out mechanism changing with radiator, uses the fin type radiator different with the die casting formula; Increased area of dissipation; According to heat distribute direction and form designs, reach better radiating effect, and quality alleviates more; Light fixture is more light and handy, can adjust the quantity of fin according to the heat radiation needs of watt level.3) use E27 screw type lamp holder, use simple and safe as the light source user installation.
Description of drawings
Fig. 1 is the structural representation of the utility model.
1 is that tubular lampshade, 2 is that planar diffusion plate, 3 is that MCPET reflecting plate, 4 is that fin type radiator, 5 is E27 screw type lamp holder among the figure.
The specific embodiment
The utility model comprises tubular lampshade 1 and is connected the planar diffusion plate 2 on the tubular lampshade 1, is provided with LED lamp pearl in the tubular lampshade 1, is provided with MCPET reflecting plate 3 in the lamp interior space.
LED lamp pearl is provided with the fin type radiator 4 that fits tightly with it.
The radiating fin of the fin type radiator 4 of the utility model can be adjusted the quantity of radiating fin according to watt level.
The utilization of the MCPET reflecting plate of the utility model can improve whole 10% light efficiency, effectively the evenly distribution of light.
The utility model adopts E27 screw type lamp holder.
