Description

A kind of super-thin high efficient LED lamp panel

(i) technical field: the utility model relates to the ligthing paraphernalia field, especially a kind of super-thin high efficient LED lamp panel.

(ii) background technology: China is a country that resource is very nervous, energy-conserving and environment-protective, and the low-carbon (LC) life, be the theme of the Scientific Outlook on Development.At present, country is vigorously advocating use energy-saving illumination product.Due to the LED light fixture energy-efficient, environmental protection is arranged, without mercury, without ultraviolet ray, be convenient to add the characteristics such as brightness adjustment control and long service life, therefore, the application of LED lamp is more and more extensive, from guidance lighting, decorative lighting, expand to the indoor and outdoor general lighting, deeply be subject to liking of consumers in general.

The current LED lamp panel come into operation on market, mainly contain two kinds: a kind of is imitative T8 or T5 LED grid or sieve aperture lamp panel, it is to imitate T8 or the T5 fluorescent tube is changed original T8 or T5 fluorescent tube by LED, another kind is the flat lamp of lateral emitting, and originally imitated T8 or T5 LED grid or sieve aperture lamp panel, mainly there are the following problems:

1. original lamp panel structure is fixed, can't carry out secondary light-distribution to LED inherent luminescence characteristic, as LED lamp pearl and reflecting piece distance and angle are to fix, more can't utilize the disk body inclined-plane to reflect to adjust, also have between LED lamp pearl and printing opacity diffuser plate distance to be subject to lamp socket that limitation is installed and fix, therefore difficult all sidedly to LED the intrinsic characteristics of luminescence carry out luminous intensity distribution;

2. the reflecting piece in original structure and grid sheet have partial luminous flux to exist the secondary light loss to have part light to reflex to reflecting piece by diffuser plate with the imitative T8 of LED or T5 fluorescent tube wastes to making a part of light can not major part be emitted to sensitive surface, particularly perpendicular to the grid sheet areflexia of fluorescent tube and dispersing of obstruction light, increased light loss, traditional grid sheet has been the fixedly effect of reflecting piece;

3. by aluminium base and aluminium radiator fin heat radiation, they and lamp panel body be without connection with LED lamp bar in the imitative T8 of LED or T5 fluorescent tube for original structure, not only increased material and process costs but also do not utilized to greatest extent the heat radiation of lamp panel body;

4. original structure is kept a public place clean and clears up with grid or the inconvenience of sieve aperture lamp panel of the imitative T8 of LED or T5 fluorescent tube, and time length affects light efficiency output and attractive in appearance;

5. for original structure, LED imitates T8 fluorescent tube lamp panel, and its driving can only be built-in, therefore needs three drivers, and cost improves, and its output voltage of making non-isolation far surpasses safe voltage and also has potential safety hazard.

Though the flat lamp light of lateral emitting is soft evenly in addition, secondary reflection and light output angle reduce to make light loss to increase, and light output efficiency is low.

In sum, the LED light fixture that designs a kind of super-thin high efficient extremely is necessary.

(iii) summary of the invention: the purpose of this utility model is exactly to solve that traditional imitative T8 or T5 LED grid or sieve aperture lamp panel have reflecting piece, grid sheet, area of dissipation is little, lamp panel is not easy to clean, delivery efficiency light is low, cost is high and have the problems such as potential safety hazard, and a kind of super-thin high efficient LED lamp panel is provided.

Concrete scheme of the present utility model is: for traditional LED lamp, improved, it has LED lamp bar, lamp panel disk body bottom that lamp panel disk body, LED lamp pearl form and driver, diffuser plate, junction block and some wires are housed form, it is characterized in that: described lamp panel disk body is provided with several trapezoidal light troughs wide at the top and narrow at the bottom, trapezoidal light trough is all one-body molded with the lamp panel disk body, diffuser plate all is equipped with at the top of each trapezoidal light trough, LED lamp bar all is equipped with in the bottom of each trapezoidal light trough, and each LED lamp bar links together by wire and driver.

For the convenient diffuser plate of installing, the top sides of trapezoidal light trough described in the utility model is along all being step-like, and the diffuser plate equipped with trapezoidal light trough is mounted on the step surface on trapezoidal light trough top sides edge.

In order to look more attractive in appearance and generous, the top of diffuser plate described in the utility model and lamp panel disk body top are all on same level.

In order to improve the reflection of light effect, farthest increase the delivery efficiency of light, the angle α of the base of trapezoidal light trough described in the utility model and hypotenuse is 120 °～160 °, the high h of trapezoidal light trough is 12～42mm.

The utility model is designed to 120 °～160 ° by the angle α of the base of trapezoidal light trough and hypotenuse, and the high h of trapezoidal light trough is designed to 12～42mm, has reduced light loss.As follows to super-thin high efficient LED lamp panel and the imitative T8 fluorescent tube lamp panel contrast test of LED by equal input 35W power:

Super-thin high efficient LED lamp panel LED imitates T8 fluorescent tube lamp panel

Luminous flux contrast: 2800 ± 100mL 2100 ± 100mL ?

Energy-conservation 30-35%(is than imitative T8 LED fluorescent tube lamp panel)

Light loss: 3-4% 15-25%

The utility model also has following advantage:

1.LED lamp band and lamp panel body are directly bonding by heat-conducting glue, and the area of dissipation of lamp panel body enlarges more than 5 times than LED T8 or T5 fluorescent tube radiating surface, so radiating efficiency is high;

2. cancel traditional grid sheet and reflecting piece, utilize the light trough inclined-plane reflective, height at the prerequisite lower compression lamp panel disk body that guarantees light distribution angle and distance, the steel of cancelling lamp socket simultaneously and connecting between grid and lamp panel disk body is buckled, cause the super-thin high efficient LED lamp panel to form integral structure manufacture lamp panel mould and only need three to five covers, and T8 or T5 grid or sieve aperture lamp panel need be gone up mold more than ten, complex process, the difficult manufacture, the thickness of lamp panel disk body is reduced to 32 millimeters by 55 millimeters simultaneously, material reduces approximately more than 35%, corresponding technique and the manufacturing cost of also reducing;

3. bright dress and concealed installation can be combined in a structure and complete, and also can be used for the suspension type lifting;

4. with three groups of outputs of a driver band, circuit is isolated, Voltage-output safety, and cost descends;

5. with Das Vorderradfahrwerkmit Vorderradantrieb, be contained in the semi-circular recesses of the radiator in imitative T8 fluorescent lamp, every LED fluorescent tube all needs to join a driver, and the utility model is contained in lamp panel disk body bottom by driver, therefore only need to share a driver just passable for whole lamp panel, reduce the quantity of driver, saved cost.

The utility model is simple in structure in a word, and the LED reflection of light is effective, and it is large that LED light to sensitive surface is derived angle, has increased the delivery efficiency of light; The height of lamp panel is compressed, and cost is low; Radiating effect strengthens, and the while lamp panel cleans also very convenient, and security is also more secure.
