Description

The LED Down lamp

Technical field

The utility model belongs to field of illumination lamp technology, relates to a kind of energy-saving type interior illumination light fixture, particularly relates to the Down lamp of a kind of LED of use as light source.

Background technology

In lighting technical field, LED (Light Emitting Diode) is progressively substituting existing light source as a kind of emerging light source.Led light source is except life-span length, power consumption are hanged down, and the advantage that also have radiationless, few heat, is easy to reclaim belongs to typical green illumination light source.

In the prior art, often use Down lamp in the decoration field, its structural advantages is to install to be hidden in building interior, and light source does not expose, free from glare, and visual effect is soft, even, is applicable to environment such as market, supermarket, office building, hotel, coffee shop, family.Along with development of science and technology, Down lamp is also constantly being weeded out the old and bring forth the new, and up-to-date is the LED Down lamp.Along with the LED technology is progressively full-fledged, reach LED and have high power savings advantages, the LED Down lamp also occurs on market successively.

But common in the market LED Down lamp is on the common plastics light-emitting plate, to form the frosted layer to carry out simple optical treatment basically, has that amount of light is low, bright dipping is inhomogeneous, problem such as dazzle is arranged.Also do not carry out any processing on the lamp inwall, cause amount of light low, light efficiency is low, fails to bring into play the high light efficiency and the green illumination advantage of led light source.

The utility model content

The technical problem that the utility model solves is to overcome the defective that prior art exists, provide a kind of and go out that light effect is good, light efficiency is high, luminous evenly, easy mounting, the LED Down lamp that is easy to dispel the heat.

The utility model is realized through following technical scheme:

The utility model discloses a kind of LED cylinder lamp structure; This LED cylinder lamp structure comprises the Down lamp housing; Be disposed with the little foaming reflecting plate of the little foaming reflecting plate of circuit board, MCPET that the LED lamp is installed, MCPET two, acrylic light-passing board and reflexed light ring in the described Down lamp housing; The porose position of little foaming reflecting plate one hollow out of described MCPET so that the LED lamp assembly of circuit board in the position, hole of little foaming reflecting plate one hollow out of MCPET, the little foaming reflecting plate two of MCPET is close on the Down lamp inner walls.

Described acrylic light-passing board is high printing opacity frosted acrylic light-passing board.

The little foaming reflecting plate of described MCPET, adopting PET is that the base material foaming is processed.The MCPET reflecting plate has outstanding reflective character (99% above total reflectivity, 96% diffuse reflectance, 3% specular reflectivity), can under 160 degree Celsius, still can keep shape, recyclable utilization, and material non-toxic is harmless, surface smoothing.Secondary operations is convenient, can cut, punching press, bending, heating.Under the situation of not adding light source, the Down lamp inwall uses this material, utilizes the principle of its optically focused reflection, can make light efficiency promote more than 50%.

The utility model has following significant effect

1, the LED Down lamp is energy-efficient, and the life-span is long, and electric energy is converted into available light efficient height, and is energy-conservation more than 75% than the common LED Down lamp.And led chip is luminous, and no filament is not afraid of vibrations, is difficult for fragmentation, and can reach more than 30,000 hours service life.

2, do not produce radiation, not mercurous, heavy metals such as lead, housing adopts aluminium.

3, the utility model Down lamp safety coefficient is high, and power demand is little, and LED can directly not expose, and overall appearance is dustproof, insect protected.

4, LED is fixed on the circuit board, and back of circuit board is coated with heat conductive silica gel, and is fixed on the planar base surface of radiator of aluminium material, and it is faster to dispel the heat.

5, housing is provided with torque spring outward, helps on ceiling, installing.

6, the utility model is sticked on the little foaming reflector of MCPET on the Down lamp inwall, improves light extraction efficiency.The LED light that can make oblique fire makes more light penetrate from the Down lamp mouth, the effective rate of utilization of raising room lighting uniformity and light in its surperficial and inner further formation diffuse reflection and reflection.

7, the utility model light-passing board adopts high printing opacity frosted acrylic light-passing board.The acrylic light-passing board have light weight, inexpensive, be easy to advantages such as moulding.The acrylic light-passing board is higher than ordinary resin plastic, transparent Du Genggao, hardness.The high printing opacity single face frosted acrylic light-passing board that the utility model adopted, have following characteristics: have high transmission rate, high mist degree, high diffusivity etc., light transmittance is up to more than 82%, and mist degree reaches more than 92%, and diffusivity is more than 0.6; Light is softer, even than common frosted acrylic light-passing board, free from glare, and cost performance is higher than the combination of any diffusion barrier and transparent panel.

8, the utility model LED Down lamp light efficiency improves more than 75%, and bright dipping is more even, free from glare.
