Abstract
The invention provides an LED panel lamp which is simple in structure and capable of effectively protecting LED light-emitting units and prolonging the service life. The LED panel lamp comprises a lamp bar, a reflector plate, a light guide plate and a diffuser plate; the lamp bar comprises an aluminum substrate and a plurality of LED light-emitting units which are evenly arranged on the aluminum substrate; the reflector plate is arranged on the top surface of the light guide plate; the diffuser plate is arranged on the bottom surface of the light guide plate; the plurality of LED light-emitting units face the light guide plate; the LED panel lamp further comprises a cushion which is arranged between the aluminum substrate and the light guide plate; the cushion is thicker than the LED light-emitting units. In the manufacturing process of the LED panel lamp, a protective element (namely the cushion) is additionally arranged between or under the LED light-emitting units to protect the LED light-emitting units after the light guide plate expands with heat, and therefore, the damage rate of the LED light-emitting units is reduced and the service life of the LED panel lamp is prolonged.
Description
Technical field
The present invention relates to the improvement to LED flat lamp.
Background technology
Owing to having the features such as energy-saving and environmental protection, high efficiency, small size, long-life, LED lamp replaces conventional incandescent and fluorescent lamp gradually.But, in general LED side-emitting lamps structure, special protection is not had to LED luminescence unit, reduces service life.Because have light guide plate in light fixture, light guide plate material is PMMA, the thermal coefficient of expansion of PMMA is at about 6X10E-5cm/cm DEG C, suppose that light guide plate is of a size of 600*600mm, when the temperature difference is at 30 DEG C, the light guide plate dilation dimension caused reaches about 1mm, and general light fixture is in design and assembly process, many as much as possible in order to ensure that LED luminescence unit directly squeezes into the light of light guide plate, improve light efficiency rate, LED luminescence unit and light guide plate gap are generally between 0.2 ~ 0.5mm, so light guide plate is easily expressed to LED luminescence unit when variations in temperature, the damage of LED luminescence unit can be caused for a long time.
Summary of the invention
The present invention is directed to above problem, provide a kind of structure simple, available protecting LED luminescence unit, improve the LED flat lamp in service life.
Technical scheme of the present invention is: comprise lamp bar, reflector plate, light guide plate and diffuser plate, and described lamp bar comprises aluminium base and some LED luminescence units, and some described LED luminescence units are all laid on described aluminium base; Described reflector plate is located at the end face of described light guide plate, and described diffuser plate is located at the bottom surface of described light guide plate, and some described LED luminescence units are towards described light guide plate; Also comprise cushion pad, described cushion pad is located between described aluminium base and light guide plate; The thickness of described cushion pad is greater than the thickness of described LED luminescence unit.
Described cushion pad is located at the below of described LED luminescence unit.
Described cushion pad is located between adjacent described LED luminescence unit.
Distance between described LED luminescence unit and described light guide plate is 0.2-0.5mm.
The present invention is in the manufacturing process of lamp bar; protection element (i.e. cushion pad) is increased between LED luminescence unit or below LED luminescence unit; protection component thickness increases 0.1-0.2mm on the basis of LED luminescence unit thickness; protect element in lamp bar circuit without electric function; after light guide plate expanded by heating, protection cushioning effect is played to LED luminescence unit; reduce the spoilage of LED luminescence unit, improve the service life of LED flat lamp.
