Description
Technical field
The present invention relates to LED technical field, particularly relate to a kind of equal electro-optical device of LED tubular from bottom-emission.
Background technology
The LED illumination lamp of high-quality, it is desirable on the lampshade of whole tubular, R, G, B mixed light must be highly uniform, does not allow the mottle having different colours on lampshade to occur, and does not allow to occur on whole barrel-shaped lampshade the situation that upper and lower brightness is inconsistent.
At present, still do not have the equal electro-optical device of a kind of LED to be capable of barrel-shaped lampshade top to be connected by wire bottom barrel-shaped lampshade, and LED light source is bottom barrel-shaped lampshade, R, G, B glory can be allowed in colour gamut even light mixing, make uniform in the upper and lower brightness of whole barrel-shaped lampshade of white light so that it is light loss minimizes simultaneously.
The basic structure of the desk lamp of tubular is at present: top is cylindric lampshade, and bottom is columnar lamp socket, and control circuit is placed on inside lamp socket.The illumination mode of lamp plate has two kinds: a kind of lamp bead is placed on the lamp plate of lampshade bottom from down light, and another kind is that lamp bead is evenly distributed on the four sides in the middle of lampshade or hexahedro lamp plate up and down.The lampshade of present tubular is in order to realize at the top of lampshade by touching regulation brightness, several buttons are put into top, realization is opened, turn off the light, recall the optical mode function of different colours, therefore must there is a lot of wire from the top of lampshade, in order to reach 360 degree of uniform light of whole column lamp body, current design is to place a strip angular column in the middle of barrel-shaped lampshade, every one side of angular column is evenly distributed 4 white lights and the lamp bead of 4 RGB unifications, coordinate the lamp bead with certain light transmittance again, reach white light uniform at whole lampshade glazed thread, glory even light mixing.But, the lamp bead quantity used in prior art is too many, and white light needs 16, the lamp bead of R, G, B unification needs 16, and the cost of lamp bead is the highest, and because each piece of lamp plate is required for and drives plate to be connected, therefore can be with 8 to adapter, packaging technology is the most extremely complex.
And use the mode of bottom-emission, and plus mixing film and pore membrane, the quantity of lamp bead can greatly reduce, the quantity of adapter uses 2 groups less, the contact area of lamp plate and base increases, the heat radiation of lamp bead can ensure, the temperature of lamp bead can and because there is the mixed light of reflective membrane to can ensure that the uniformity of glory mixed light, pore membrane can ensure that the upper and lower uniformity of whole lampshade light, and light is at mixing film, pore membrane, constantly reflect between lampshade, launch, the light sent from lampshade is the softest, eyes will not be injured after human eye direct-view light, the demand of high-quality light can be reached.
The matching relationship of which floor cover, such as: pore membrane distance lampshade is too near, and lampshade arises that obvious hole shadow.Pore membrane and mixing film distance lamp bead are too near, because the top center of lampshade has wire to bottom, when the lamp bead of two kinds of colors of R, G, B is bright, lampshade there is also different mottles, should be to mix out yellow green, and result redness and green mottle are on lampshade.And there is reflection shield above, by vertically according to upper light, reflexing on outer housing, the loss of the light thus being avoided that, raising light efficiency, 360 degree of whole lampshade, the most uniformly.Use the special white paint of optics on lamp plate bottom light can be transmitted into top play the effect improving whole lumen value.
Summary of the invention
Present invention aims to above-mentioned technical problem, a kind of equal electro-optical device of LED tubular is provided, this device is from bottom-emission, design simple in construction, low cost, it is possible to realize the uniformly light-emitting of whole lamp body, different colours glory uniform, without hot spot, make white light at the upper and lower brightness uniformity of whole barrel-shaped lampshade.
A kind of equal electro-optical device of LED tubular, including lampshade, lamp socket, lamp plate, lamp bead, master control borad, mainboard bracket, PC transparent tube, pore membrane, mixing film and driving plate；Described lamp plate is fixed on cylindric lampshade and the joint portion of lamp socket, and described lamp bead includes white light lamp bead and RGB lamp bead, is uniformly fixed on lamp plate；Described master control borad is installed on the mainboard bracket at lampshade top, and is connected with lamp plate by FFC line；Described mainboard bracket is bowl shaped structure, has the groove bottom the groove of circle, described PC transparent tube top and mainboard bracket to connect and fix bottom it, and its underpart is connected with lamp plate, plays the effect supported up and down；There are three limited posts on described lamp plate, intermediate supports cylinder can be given spacing.
Described pore membrane and described mixing film fit together, and make a cylindrical shape and are placed in PC transparent tube, and its length is consistent with PC transparent tube.Described mixing film is mylar, and by diffuse-reflectance by R, G, B light even light mixing, its mist degree is 80%, and light transmittance is 90%, a length of 150mm, and width is 150mm, and thickness is 0.1mm.Described pore membrane aperture from bottom to top becomes larger, and by adjusting light transmittance, makes the upper and lower brightness uniformity of desk lamp.
Described lamp plate be radius be the circular aluminum substrate of 48mm, 8 white light lamp bead are had on lamp plate, lamp bead is evenly distributed on lamp plate as the center of circle, radius 20mm is on circular arc, RGB lamp bead is evenly distributed on the circular arc that radius is 15mm successively, angle between adjacent R, G, B lamp bead is 60 degree, is respectively equipped with two R, G, B lamp bead.
Described driving plate is installed on bottom lamp socket, it is connected with the master control borad at top by FFC line, it is fixed on the adapter of master control borad above FFC line, there is a rectangular groove at the center of lamp plate, FFC line is through being presented herein below on the adapter being fixed on driving plate from hole, and white light is uniformly distributed in the isocentric circular arc with lamp plate as the center of circle.
Although the light of the equal electro-optical device of the present invention is blocked by central conductor, by mixing in mixing film and the reflection of top optical light-emitting area and the reflection of bottom lamp plate, light is not the most uniform.It is upper and lower bright dark that pore membrane is used to light regulating, the light that light is radiate by pore membrane mixing the most again；Then, light is again through the reflection of two-layer lampshade, mixing again, and such light is achieved that mixed light fully in space, the light finally sent from lampshade will brightness up and down, light is soft, will not produce hot spot.
The equal electro-optical device of LED tubular of the present invention uses the form of bottom-emission, it is achieved that the uniformly light-emitting of whole lamp body, the glory of different colours uniform, without hot spot, makes white light at the upper and lower brightness uniformity of whole barrel-shaped lampshade.The quantity of the lamp bead that the illumination mode of this structure uses is few, and the usage quantity of other electronic devices reduces, it is achieved that distribute rationally, greatly reduce cost, the power of whole lamp, energy-conserving and environment-protective can be reduced simultaneously, be capable of the optical effect that other illumination modes can not reach simultaneously.
