Abstract
The utility model discloses a light-emitting diode (LED) lighting device which comprises a frame, a back plate, an LED light bar, a piece of reflective sheeting, a diffusion plate and a power supply. The back plate is embedded in the frame, the LED light bar is attached on the frame, the reflective sheeting is attached on the back plate, the diffusion plate is located below the frame and arranged perpendicular to the frame, and the power supply is externally placed on the back plate. Light emitted from a lamp bead on the LED light bar performs a second time of light equalizing through the diffusion plate after a first time of total diffuse reflection of the reflective sheeting is performed, and the emitted light is enabled to achieve 94.6% in evenness degree. The emitted light is very soft, and when the LED lighting device is used, the eyes of a user are not prone to feel discomfort. The LED lighting device is simple in structure, and easy to produce and manufacture.
Description
Technical field
The utility model relates to the LED lighting technical field, and particularly relate to a kind of equal luminosity and reach 94.6%, during use, the LED lighting device that the human eye comfortableness is strengthened greatly.
Background technology
In the situation that global energy is in short supply, LED as a kind of novel illumination light source by popularization and application more and more widely, particularly stated the production of cancelling incandescent lamp and used electricity-saving lamp instead in some national government, nowadays office lighting is mainly grid lamp disc, but it luminously has the light of dazzling, and allows produce light fatigue its clerical workforce, so panel light occurred, panel light is mostly the band LGP in advance, but its acrylic is extremely unstable and cost is expensive, and one is really restricting the popularization of panel light.Under inscribing before this, design the equal photosensitiveness of a height, in use procedure, make the comfortable LED lighting device of human eye perceives particularly important.
The utility model content
Technical problem to be solved in the utility model is to strive to the needs of actual life and a kind of LED lighting device is provided, this lighting device adopts reflective sheeting to carry out diffuse reflection to the light that LED light source produces, and re-uses the light of diffuser plate after to diffuse reflection and carries out equal light action.It is soft to make auroral poles that final human eye experiences, solves traditional grid lamp disc and easily produces the problem of dazzling light.
The technical problem that the utility model requires to solve can be achieved through the following technical solutions:
A kind of LED lighting device, comprise frame, backboard, LED lamp bar, reflective sheeting, diffuser plate, power supply, described backboard is embedded in frame, described LED lamp bar is attached on frame, described reflective sheeting is attached on backboard, described diffuser plate is positioned at the frame below and arranges with frame perpendicular, and described power supply is placed on backboard.
Also comprise lampshade, described diffuser plate and frame are arranged in the acute angle mode.
Described reflective sheeting upper end is arc.
Owing to having adopted as above technical scheme, the utlity model has following features: the utility model is simple in structure, easy for installation, and all photosensitiveness up to 94.6%, solves traditional grid lamp disc and easily produces the problem of dazzling light, in use procedure, makes human eye perceives very comfortable.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, the utility model mainly includes: the frame 3 that aluminium alloy is made and backboard 2, and this frame has heat sinking function, allows LED lamp bar 5 be attached on frame 3 by bond plies; Aluminium frame 3 with heat conduction function, on LED lamp bar 5, uniform LED lamp pearl makes on the average importing aluminium frame 3 of heat and is dispersed in air.
During concrete enforcement, the light belt that LED lamp pearl disperses out has beating in the above on the reflective sheeting 4 with radian of certain angle, and reflective sheeting 4 carries out for the first time all light with the total diffuse reflection function to the light that LED lamp pearl sends.
During concrete enforcement, light carries out for the second time all light through after the total diffuse reflection for the first time of reflective sheeting 4 by diffuser plate 6, and the light that makes out reaches 94.6% Zhuo evenness.
During concrete enforcement, power supply 1 is external to be placed on backboard 2, its heat that sends directly is dispersed in air goes.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
