Description
Technical field
The utility model is related to LED field, more particularly to a kind of side entering type flat LED light fixture.
Background technology
In recent years, based on energy-conserving and environment-protective, efficiency high, small size, long-life the features such as, LED is increasingly by consumer
Favor, particularly LED flat lamp permeability in architectural lighting gradually steps up, and is on the one hand that LED flat lamp lighting area is big,
Light is soft uniform, can build comfortable, warm Interior Illumination Environment, and the color developing of LED flat lamp is outstanding, may be used also
With realize brightness, colour temperature, color conversion, in addition buy house the multipair LED of main body consumer groups cognition degree it is higher, be ready
The LED lamp of environmentally friendly, excellent optical performance is selected as the main body of room lighting.But current plate type LED light fixture is universal
Come with some shortcomings, such as the defect such as light extraction efficiency is relatively low, on the high side, relatively heavy, radiating effect is bad.
Utility model content
The defect for aiming to overcome that prior art of the present utility model there is provided a kind of side entering type flat LED light fixture,
Including light fitting frame, LED light bar, diffuser plate, reflector, the light fitting frame is horizontally disposed, and the LED light bar is set respectively
In the left and right sides of the light fitting frame, the diffuser plate is arranged at frame upper side, and the reflector is arranged at framework underside.
The LED light bar includes LED lamp bead, reflector, and the LED light bar of described the right and left has be lifted up small
Angle, the LED lamp bead to be oval, the LED lamp bead LED light bar in the plane be projected as ellipse, and this
The major axis of ellipse is parallel with the length direction of the LED light bar, and the oval LED lamp bead can be sent and the LED light bar
The parallel prolate light of length direction, the prolate light forms the overlay region of multiple uniform lights, institute on the diffuser plate
It is the oval reflector matched with the LED lamp bead to state reflector, can preferably strengthen the convergence of the LED light bar light
And directionality.
The diffuser plate is located at the front of light extraction, and the reflector is located at the back side of the light extraction, and the diffuser plate is
PMMA materials are made, and the surface of the diffuser plate is provided with parallel raster-like striped.
During the side entering type flat LED light fixture work, the divergent beams that the LED lamp bead is sent, into the reflector
It is interior, converged in through reflector on described diffuser plate, from side, the light beam after being converged through reflector is narrower, and from diffusion
Plate front observation, light beam is wider.Reflected and directly thrown after cylindrical lens convergence by reflector due to light beam
It is mapped on diffuser plate, the multiple reflections loss without deflector, so the light extraction efficiency of the side entering type flat LED light fixture compares one
As light guidance board type flat lamp outgoing efficiency it is high.On the other hand, the lamp bead with it is coaxial centered on the mounting hole of the reflector
Set, the light beam after reflected optically focused on diffuser plate, is radiated at the light beam of the diffuser plate close with smaller angle graze
The luminous intensity of the side of reflector is smaller, and the luminous intensity on reflector and the main shaft of lamp bead is maximum, due to entering for the latter's light
Firing angle（The angle of light and diffuser plate normal）It is bigger than the former, so the numerical values recited of the illumination in unit area on the side
It can accomplish to be basically unchanged, and light beam is in the side of principle reflector, because luminous intensity is small and incidence angle big, therefore illumination is also small,
So the central area of diffuser plate is the superposition of the light beam of two LED light bars, make the illumination of central area and both sides basically identical, then
After the scattering process of diffuser plate, the area source of light distribution average price is can obtain, outgoing is uniform, and light is also soft.
Due to being not provided with deflector in LED light bar, during work, two LED light bars are inwardly and direct irradiation spreads obliquely
Plate, most of light is scattered to form uniform planar light, and the direct or indirect small part light in reflected light also can be anti-
Penetrate, shed through diffuser plate, ultimately form the area source of homogeneous soft, because light after diffusion before projecting, reflected time
Number is few, and light loss is small, and light emission rate is high, overcomes traditional LED flat lamp defect such as light extraction efficiency after light guide plate multiple reflections.
Radiator structure is additionally provided with the outside of the LED light bar, the radiator structure includes pipeline, deflector, the LED
One layer of block is provided with the outside of buttress brace, the buttress brace and is provided with " Contraband " pipeline outside bar, and " Contraband " the font pipeline material is
One kind of plastics, aluminum or aluminum alloy material, the duct thickness is less than or equal to 2mm, and the pipeline is set with LED light bar opposite side
There is deflector, the deflector is the compression molding structure of metal material, and thickness is less than or equal to leading in 0.5mm, the pipeline
Stream plate is formed with wave stripe, and the lug boss of the wave stripe is corresponding with the LED lamp bead of the LED light bar, the ripple
The wavelength of unrestrained striped is equal with the spacing of adjacent LED lamp bead.The distance of crest to trough is less than or equal to the half of wavelength,
This structure, which can be prevented effectively from the depressed part of wave stripe, is detained or is formed whirlpool, and gas-flow resistance is small, and ensures in whole passage
Air flow, strengthen radiating effect.
Radiator structure used in the utility model, forms " chimney " structure, LED light bar is to the air in pipeline using pipeline
Heated, the principle that easily floats small using hot-air density makes the air in pipeline be clapped away upwards along pipeline, new air
Supplemented by lower end, increase the mobility of the air in the pipeline of LED light bar rear with this, carry out unimpeded, quick free convection
Radiating, and the depressed area of wave stripe is used to store enough air, the boss of wave stripe because with LED light bar
The spacing little airflow flow velocity at the back side is big, if corresponding to the position of LED lamp bead herein, can dramatically speed up the air stream at the LED lamp bead back side
Speed, and then strengthen thermal diffusivity, without setting radiator structure in addition, overcome the radiator structure of traditional wall-hanging LED flat plate complicated, scattered
The defect such as thermal effect is poor, weight is big.
The beneficial effects of the utility model are：LED lamp has lightweight, cost low, simple and reasonable, practicality
By force, the advantage of good heat dissipation effect.
