Description
Technical field
The present invention relates to a kind of light fixture, particularly relate to the Modular panel lamp using LED or other miniature lamp bead to constitute.
Background technology
Existing LED flat lamp is divided into according to illumination mode: side entering type and straight-down negative LED flat lamp two kinds.
Side entering type LED flat lamp is mainly by frame support, the diffuser plate set gradually up and down, reflector, light guide plate, the multiple lamp bars being oppositely arranged with the edge of light guide plate respectively, and drives composition.The topmost function of light guide plate is will be by the direction of light navigation designing, and optical material has PS polystyrene, PC poly-carbonic acid vinegar, PMMA (poly-methyl methacrylate vinegar) acrylic material etc..The deficiency of side entering type flat lamp is predominantly: first, and it is the highest that efficiency is not allowed to be easy to do, and area is less susceptible to the most greatly do.Second, heavier-weight, price is higher.Light guide plate is the core of side entering type flat lamp, and price is higher than straight-down negative;3rd, higher to light guide plate prescription, if designing bad,
There will be middle bright, both sides are dark, or enter plain edge and have a bright border, or the phenomenon such as different angles brightness is inconsistent, affect lighting quality.4th, unfailing performance is relatively poor, owing to light guide plate, reflective ink and reflectance coating are located at a relatively high temperature all the time, it is easy to aging yellowing, causes light emission rate to reduce, and lamp life is had a greatly reduced quality.5th, lamp bar is oppositely arranged, and light source utilization rate is relatively low.
Straight-down negative LED flat lamp then by frame support, diffuser plate, drive, be furnished with the plane of LED particle to form.Straight-down negative LED flat lamp structure is similar with side entering type, and simply light source is evenly distributed on after diffuser plate, for comparing side entering type, can not be made the thinnest, light source can not be too near with the distance of diffuser plate, so whole lamp size is thicker, but efficiency is more much higher than side entering type.Direct type flat plate light be mainly disadvantageous in that can not be made the thinnest, to have certain spacing between LED light source and diffuser plate, otherwise light fixture can produce bright spot, and this certainly will cause the thickness of light fixture to increase, the cost making lamp outer casing and then increases, and the outward appearance of light fixture also can seem the best.And thickness adds, just increase the delivering path of light, make the efficiency of light fixture reduce.Owing to lamp bead is integrally fixed on postnotum, if postnotum full wafer aluminium base, so cost will be the highest, if with the aluminium base of bar shaped, fixing and location etc. is again a problem.If the postnotum of direct type flat plate light uses the aluminium sheet in big face, also to consider to lift the problems such as postnotum bending for a long time.
Summary of the invention
The technical problem to be solved is to provide a kind of simple in construction, module number can arbitrarily increase and decrease, change Modular panel lamp convenient, that light source utilization rate is higher.

As preferred embodiment, described pcb board is fixed on the bottom of a heat sink, and this heat sink is connected on frame support by insulating part.
As further preferred embodiment, the part in the center through hole being in light guide plate on described pcb board is additionally provided with multiple LED；The center through hole of described light guide plate is provided with inner ring light conductor, and the lower surface of this inner ring light conductor is suitable to cover the center through hole of described light guide plate.
As further preferred embodiment, described inner ring light conductor central authorities are fixed with bolt, and this inner ring light conductor is by described bolt and is threaded io bottom described heat sink, is fixed on bottom described heat sink by described light guide plate simultaneously.
As further preferred embodiment, described light guide plate is rounded or square.
As further preferred embodiment, there is multiple vent between heat sink and frame support, heat sink is evenly distributed with multiple ventilation pod apertures, i.e. constitutes heat dissipation channel, cold air enters from each ventilation pod apertures, discharges from above-mentioned vent after heat exchange.
As further preferred embodiment, described heat sink being fixed with power supply, described frame support is provided with backboard, and described power supply is located at below this backboard.
As further preferred embodiment, the end face of described light guide plate and inner ring light conductor is coated with reflectance coating.
As further preferred embodiment, described light guide plate be provided with at least 2 flangings away from the part in described center through hole.
As further preferred embodiment, each power sources in parallel in the plurality of flat lamp module being disposed adjacent, the power supply of respective numbers is i.e. selected according to module number；Due to multiple lower powered power supply price sums, less than the price of single large power supply, therefore can be the most cost-effective.
