Description

A kind of free drive flat lamp

Technical field

The utility model relates to a kind of flat lamp, in particular for the flat lamp of removing drive power supply from of the Integral ceiling of kitchen, office space.

Background technology

At present, LED has started to popularize, the structure of LED is generally by power supply, lamp plate, shell three part forms, LED flat lamp is a member of LED extended familys, be widely used in kitchen, office space, business shop front occasion, existing LED flat lamp is by driving power, lamp bar, lamp door, diffuser plate, shadow shield, light guide plate, box composition at the bottom of lamp, driving power generally adopts isolating switch power, and make waterproof form, be connected with adopting inserting mode between lamp, within several years, numerous client's installation and maintenance are given through our company, find that the lamp bar of flat lamp is generally not easy to damage, but driving power is easy to damage, because driving power is independently, installation neither be very convenient, seem also unsightly.

Utility model content

Easily damage to overcome existing flat lamp driving power, due to driving power be independently, installation neither easily, seem also inaesthetic shortcoming, the utility model proposes a kind of free drive flat lamp with head it off, its good effect is: adopt a kind of free drive flat lamp, use free drive lamp bar, eliminate the flimsy driving power of appearance, made flat lamp more durable, more attractive in appearance.

The utility model solves the technical scheme that its technical problem adopts: a kind of free drive flat lamp of the present utility model, be made up of box at the bottom of lamp door, diffuser plate, light-shielding sheet, light guide plate, LED free drive lamp bar, lamp, lamp bar in flat lamp uses LED free drive lamp bar, and the element use on LED free drive lamp bar has silicone insulation, protection against the tide.

The technical solution adopted in the utility model will coordinate accompanying drawing to elaborate in a particular embodiment.

Accompanying drawing explanation

Here is brief description of drawings.

Fig. 1 is a kind of free drive flat lamp structural representation (driving power does not draw) of the present utility model.

1. lamp doors, 2. diffuser plate, 3. light-shielding sheet, 4. light guide plate in figure, 5.LED free drive lamp bar, 6. box at the bottom of lamp.

Detailed description of the invention

In the embodiment in figure 1, we further illustrate the utility model to implement a kind of free drive flat lamp:

Fig. 1 is a kind of free drive flat lamp structural representation of the present utility model, and in figure, lamp door 1 is welded for aluminium section bar, generally has 300mm*30mm, 300mm*600mm, 600mm*600mm plurality of specifications, determines as required, diffuser plate 2 essence is one piece of square milky white acrylic board, plays the effect of diffusing light, and light-shielding sheet 3 is for stopping the effect of light, light guide plate 4 is for evenly importing flat lamp inside luminous for surrounding lamp bar, and general processing mode has laser dotting and printing two kinds, and rear a kind of cost is low, uses often, LED free drive lamp bar 5 is key component of the present utility model, existing lamp bar is generally be connected on aluminium base with 3014 lamp bead welds to form, not containing power drives, its power drives is external in outside lamp, the utility model adopts free drive lamp bar, namely power supply process and LED lamp bead are integrated on a bar shaped aluminium base, the linear constant-current circuit of this integration mode, the application number of Chongqing Lin Meng Electronic Science and Technology Co., Ltd. (our company) application on June 28th, 2015 is the circuit structure of 201520447374.8 " a kind of small-power table new capacitance-resistance driving LED one lamp plates " in addition is also one free drive lamp plate very reliably, be particularly suitable for manufacturing free drive flat lamp, LED free drive lamp bar 5 silica gel manufactured is attached on lamp door 1 fixing, element on lamp bar uses transparent silica gel to do protection against the tide, insulation processing, ensure use safety, box 6 at the bottom of lamp is exactly one piece of thin metal cover board.

Have employed scheme of the present utility model, make flat lamp free drive driving power, the life-span is longer, and outward appearance is more beautiful, better installs.
