Abstract
The utility model relates to a direct light type LED flat lamp, which comprises a lamp frame, an acrylic face plate, LED lamp panels, a rear cover board and a constant-current power supply, wherein the lamp frame is formed by aluminum profiles in an assembling manner; the acrylic face plate is inserted in a groove formed on the lamp frame; a plurality of the LED lamp panels are fixed on the rear cover board; the rear cover board is fixed on the rear frame surface of the lamp frame; the constant-current power supply is fixed in a cavity formed on the lamp frame; and the constant-current power supply is connected with the LED lamp panels through conducting wires. The direct light type LED flat lamp has the benefits as follows: the luminous flux utilization ratio is high, and the radiating area is increased so as to lead the radiating effect to be better; all the luminous surfaces of the direct light type LED flat lamp face to the luminous surfaces of a lamp, so that luminous flux loss can be reduced greatly, rays can be uniformly distributed in the area that is illuminated, and life and work can be facilitated better; in addition, little pollution and long service life can be achieved.
Description
Technical field
The utility model relates to a kind of illuminating LED straight-down negative flat lamp such as family, hotel, shop that are widely used in.
Background technology
There is following defective technically in existing fluorescence flat lamp:
1. luminous intensity distribution: it is luminous that fluorescent lamp belongs to circumference, can not 100% gets light;
2. thermal diffusivity: fluorescent lamp belongs to gas discharge, causes the light fixture heating, adds the ballast heating, the gross calorific power height;
3. Luminaire efficiency: the Luminaire efficiency of fluorescent lamp is low, is unfavorable for energy-conservation;
4. light pollution: have infrared ray, ultraviolet radiation, can cause the aging of light fixture;
5. service life: fluorescent tube is approximately 8000h service life;
6. maintenance cost: light source need regularly replace, and lamp surface needs cleaning;
7. pollute: pollution elements such as leaded, mercury; Therefore, demand a kind of novel household flat lamp urgently and substitute the fluorescence flat lamp.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of LED straight-down negative flat lamp.Solved the deficiency that existing high-pressure mercury lamp bulkhead lamp capable exists.
The utility model for achieving the above object, the technical scheme of being taked is: a kind of LED straight-down negative flat lamp, it is characterized in that: comprise the lamp door, acrylic panel, LED lamp plate, back shroud, the constant-current supply that constitute by the aluminium section bar assembling, described acrylic panel is inserted in the groove that lamp door is provided with, the described LED lamp plate of several piece is fixed on the back shroud, back shroud is fixed on the after-frame face of lamp door, described constant-current supply is fixed in the cavity on the lamp door, and constant-current supply is connected with the LED lamp plate by lead.
The beneficial effects of the utility model are:
1. luminous intensity distribution: it is luminous that LED straight-down negative flat lamp belongs to single face, the utilance height.
2. heat radiation:, therefore do not have heat radiation because LED belongs to cold light source.The straight-down negative flat lamp evenly is arranged in LED lamp pearl on the circuit board, and is close to the flat lamp backboard, and area of dissipation increases makes better heat-radiation effect.
3. the luminous efficiency of Luminaire efficiency: LED will be higher than the luminous efficiency of fluorescent lamp far away, therefore uses LED also will be higher than the light fixture that uses other light sources far away as the Luminaire efficiency of light source.The light source that common fluorescent tube flat lamp is used is a fluorescent tube, and 360 ° of luminous structures cause a large amount of light according to the flat lamp back side, cause the logical loss of light, and LED straight-down negative flat lamp light-emitting area has greatly reduced the logical loss of light all towards the lamp luminescence face.
4. original common fluorescent tube flat lamp light-emitting area blackening is very obvious, the light and shade zone is very obvious, give people's vision negative impact bigger, the light-emitting area Illumination Distribution of LED straight-down negative flat lamp is very even, and whole structure is very soft, and visual effect is given tranquil comfortable sensation, all very helpful to physical and mental health, and aspect illuminating effect, more not having the appearance of dark space, light can be evenly distributed in the illuminated zone, helps live and work more.
5. pollute: by CE and ROHS standard authentication.
6. service life: LED straight-down negative flat lamp is approximately 50000h service life.
