Description
Technical field
The utility model relates to illuminating LED fluorescent tube of a kind of general room and light fixture, particularly has the LED fluorescent tube and the light fixture of fluorescent tube, support, being combined into one of driving power design feature.
Background technology
The LED illumination is a kind of energy-saving illumination technology that has a extensive future, and has many advantages.Fluorescent tube is commonly called as fluorescent lamp, is widely used One's name is legion.In view of energy-conservation, life-span, environmental protection cause, the conventional fluorescent fluorescent tube is begun by the process that the LED fluorescent tube replaces.But, the LED fluorescent tube is except that on the high side and market cognition degree are hanged down, at present relatively more outstanding performance issue is that the fluorescent tube light-emitting uniformity is relatively poor, and temperature rise is big and the power supply index is relatively poor, and relatively more outstanding application problem is that unreasonable causing of structure newly install and replace that all senses are installed is inconvenient.
The conventional fluorescent fitting structure is made up of several parts, fluorescent tube, support, starter and ballast.When newly light fixture being installed, support is installed on the house ceiling, and fluorescent tube is fixed in the lamp seat at support two ends by the lamp holder at its two ends.Many years ago, support is made the reflector form with the sheet metal material, and the reflector top is gone up starter and ballast are installed, and lamp is sat and is contained in reflector downside two ends.Now aluminium alloy extrusions supports of using more, cross sectional shape is square groove shape or the rectangle that opening makes progress, lamp is sat and is contained in support downside two ends, and starter and ballast are contained in the support cavity or contain in the lamp seat of inner chamber, and the florescent lamp fitting proportion of this new construction also day by day increases.When newly light fixture being installed, the new construction florescent lamp fitting is convenient to reduce the aerial installing engineering amount at house ceiling place; When replacing the installation fluorescent tube and safeguarding, also be convenient to reduce labour cost.
The composition of LED tube lamp is similar to the conventional fluorescent light fixture, comprises LED fluorescent tube, support, driving power.Wherein, the LED fluorescent tube is made up of shell, led light source plate, radiator and lamp holder again.The industry driving power that the LED fluorescent tube is required is divided into power supply external and built-in two types, and the fluorescent tube of external separates with power supply, with lead-in wire by the lamp on the support sit, lamp holder on the fluorescent tube is finished the output of power supply direct current and fluorescent tube is connected; Built-in fluorescent tube and power pack are lumped together, need not when lamp installation, connect separately.
When new installation light fixture and replacement installation fluorescent tube, the on-chip power formula is all convenient than external, and mounting cost is lower.At present, on-chip power formula LED fluorescent tube roughly has two kinds of versions.In a kind of plastic cylinder that power supply is contained in lamp tube ends, outside diameter of cylinder is close with the fluorescent tube external diameter, is referred to as end and adorns built-in; Another kind of power supply is contained in led light source backboard face in the fluorescent tube, between printed board and radiator, is referred to as the back of the body and adorns built-in.These two kinds built-in LED fluorescent tubes are not only installed inconvenience because structure is unreasonable, have also influenced performance, have increased cost.End is adorned three defectives of built-in obvious existence.At first, the two ends not bright dipping of cylinder of dress power supply, the general about 60～80mm of its combined length causes that luminous zone length surpasses 10% of 600mm fluorescent tube, and 5% of 1200mm fluorescent tube influences illumination intensity distribution and illuminating effect.The second, the shape of cylinder, length and restricted diameter, the driving power plate is limited to very little, can only design better simply circuit, makes circuit efficiency low, and constant-current characteristics is bad, and power factor and harmonic characterisitic are poor.The 3rd, power source life always is lower than the led light source life-span, when power supply is changed in user's maintenance, need carry out the fluorescent tube dismounting and the assembly technology of manufacturing works, and this is infeasible.The back of the body is adorned built-in present consumption and is adorned built-inly more than end, and it might overcome end and adorn three built-in problems, but also obviously has two problems.At first, tube diameter is little, standard T8 fluorescent tube external diameter 26～28mm only for example, the fluorescent tube inside radius is not more than 12～13mm, power panel under being in the semicircle space, to install, light source board must have enough height behind, make conversely the light source board front LED to tube wall apart from shortening, even be short in the 10mm fluorescent tube light-emitting uniformity variation.Secondly, also for power panel down is installed, the heat dispersion of radiator is difficult to carry out, and causes the fluorescent tube temperature rise bigger, for example reaches more than 30 ℃, makes the LED junction temperature higher, and the light output attenuatoin due to the temperature rise might reach 15%.In addition, no matter the power supply external still is the on-chip power formula of two kinds of versions, does not all realize the integral structure of fluorescent tube and lamp bracket.
The utility model is understood above-mentioned technical background, therefore proposes a kind of integral LED fluorescent tube of novelty and the technical scheme of light fixture.Scheme has the design feature that fluorescent tube, support, driving power are combined into one, and not only is convenient to more install, and also has multinomial performance advantage and cost advantage simultaneously.
Summary of the invention
For solving the unreasonable various problems that causes of combining structure of main members such as shell in existing LED fluorescent tube and the light fixture, light source board, radiator, lamp holder, support, driving power, the utility model proposes the technical scheme of a kind of integral LED fluorescent tube and light fixture.
The main structure body of this programme is a support, and except playing the original lamp installation effect of conventional fluorescent lamp support and LED tube stand, it still is the radiator of light source board and the shell radiator of driving power plate simultaneously, and shell and lamp holder also are assemblied on the support.Support is made type by the aluminum alloy materials hot-drawn, and cross sectional shape is the approximate rectangular of long edges and grooves down, and the groove cross section is the isosceles trapezoid that does not have the bottom, and there is the draw-in groove of two indents in two outsides of groove.LED is installed in and forms light source board on the metal base printed board, and light source board is adjacent to assembling by the groove of thermally-conductive interface and support is flat.Shell is by the extrusion modling of optical plastic material, cross sectional shape is generally the semicircle of band opening, also can be other shape of band opening, for example shapes such as garden arc, pros, rectangular, ellipse, open outer side has the card article of two evaginations, and the evagination card article of shell is installed in the indent draw-in groove of support.Above-mentioned two installation step finish light source board and shell assembles to the combination of support.In this case, driving power need not shell, and the driving power plate is placed in the support cavity, is fixed on not to be with on long limit of going up of groove or the inner side edge, finishes the driving power plate and assembles to the combination of support.According to the cross sectional shape and the size of support and shell combining structure, in the lamp holder inboard, design the pit shape and the size in relative support and shell cross section, lamp holder is covered support and shell seals, finish the combination assembling of lamp holder and support, shell.In the lamp holder outside, the fluorescent tube of the routine size installation code that does as usual is participated, but being not so good as common practice center line such and lamp holder, the line between participating coincides, but partially on center line.Except that above-mentioned machinery assembling, in corresponding steps, the circuit of also finishing driving power plate, light source board and lamp holder successively is connected.
This programme is integral main member reasonable combination such as shell, light source board, radiator, lamp holder, support, driving power, and structure both had been fit to the new installation of light fixture, and the replacement of being convenient to fluorescent tube is again installed, and also has the advantage that multinomial performance is good, cost is low.
Integral LED fluorescent tube of the present utility model and light fixture have many advantages.At first be to use easy row easy for installation.New when light fixture is installed, support fixed or is lifted on the ceiling get final product, to have save fluorescent tube has been assembled to support, driving power is exported the process that is connected to the lamp tube light source plate; When replacing the conventional fluorescent fluorescent tube and installing, whole integral structure as fluorescent tube, is installed on the support original before replacing and gets final product.Next is to help improving performance.LED in the rack groove is to the distance of tube wall even can be increased to 20mm, and the light-emitting uniformity of fluorescent tube inboard is improved; When obtaining the high uniformity of fluorescent tube outside bright dipping with the tube wall scattering method, because of the light-emitting uniformity of fluorescent tube inboard was improved already, can adopt slight scattering to reduce optical energy loss, consequently if the constant then light output of power is higher, or same light is exported the then lower more power saving of power; Be installed in the support radiator by thermally-conductive interface with light source board, area of dissipation is bigger, and heat dispersion is better, and the radiator temperature rise is lower, and the LED junction temperature is also lower, and the light output attenuatoin is less than 10% due to the temperature rise; Lay the support cavity long enough of power panel, power panel size design nargin is abundant, both has been beneficial to indexs such as efficient, constant current, harmonic wave and power factor are carried out, and is beneficial to power supply heat sinking again and improves power supply stability.The 3rd, aspect economy, both reduced the product cost of producer, saved the expense of user's installation and maintenance again.
