Description
Technical field
The utility model relates to the architecture advances of lighting, particularly relates to a kind of improvement structure of electronic ballast circuit plate.
Background technology
The energy is the great strategic issue that concerns China's economic development, social stability and national security, also is the focus that social each side is paid close attention to.Implementing the green energy conservation illumination is the important ring of energy savings engineering, helps the sustainable development of China.Also using inductance type (use Inductive ballast) light fixture in the prior art in a large number, this lamp luminescence efficient is low, and the loss ratio of Inductive ballast itself is bigger, and the energy utilization rate of light fixture is very low.And electronic type (use electric ballast) lamp luminescence efficient height, and the loss of electric ballast itself is also smaller, is a light fixture more efficiently.Utilizing electric ballast to make various light fixtures efficiently is a kind of practical needs that lighting energy saving is transformed.Traditional electronic ballast circuit substantially all is to be integrated on the pcb board, and element is too intensive, be unfavorable for that heat radiation or PCB wiring board volume are excessive is unfavorable for that the light fixture assembling produces.
In addition, use to adopt traditional T8 daylight light fixture of Inductive ballast, its fitting structure schematic diagram as shown in Figure 1, T8 light fixture 200 comprises T8 fluorescent tube 60, T8 support 20, Inductive ballast 202 and starter 203 among the figure.T8 fluorescent tube 60 is traditional T8 halogen powder fluorescent lamps in the prior art.The lighting energy utilization rate of this traditional light fixture is very low.Major defect shows: 1. adopt traditional T8 halogen powder fluorescent tube, luminous effect is low, colour rendering is poor, light decay is fast; 2. adopt the ballast of inductance type, power factor is low, own loss is big, noise is arranged, lamp stroboscopic etc.For energy-saving and cost-reducing, generally adopt novel T5 Fluorescent Light and Fixtures light fixture to replace old-fashioned T8 daylight bracket lamp at present in the society.And will disassemble the last T5 bracket lamp that changes the outfit to original T 8 bracket lamps are complicated hard works, and the energy-saving effect of general T5 bracket lamp is very unobvious, replace T8-40W, energy-conservation about 30% as T5-28W.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of separate type electronic ballast circuit plate of being convenient to make various efficient light fixtures.
For solving the problems of the technologies described above, the utility model provides a kind of electronic ballast circuit plate, it is characterized in that, is made up of two separate type wiring boards; Be electrically connected by lead between described two separate type wiring boards.
Described two separate type wiring boards all adopt the two-layer wiring plate.
The electronic devices and components of described two separate type wiring boards are made of SMD element and pins type element.
Described two separate type wiring boards become first wiring board and second wiring board, chokes electric coil L1 in the circuit of electronic ballast, startup capacitor C 2 and protective tube F1-S are distributed on described first wiring board, and remaining circuit in the circuit of electronic ballast and element are assigned on second wiring board.
The electric ballast PCB pcb equipment of the utility model separate type can be separated main heater element on the electronic ballast circuit plate, and the volume that makes an original PCB wiring board reasonably is assigned on two pcb boards of separating, and makes things convenient for the assembling production of light fixture.Further adopt the two-layer wiring plate, be more conducive to the reasonable line arrangement of electronic ballast circuit on pcb board than traditional single face wiring plate, more reduce the required area of pcb board, each electronic devices and components is made of SMD element and pins type element, the reasonably combined volume that can dwindle the electronic ballast circuit plate of multi-form element.Two separated circuit boards of the electric ballast PCB wiring board of described separate type are electrically connected by power line, because power line bendable zigzag folded, the PCB wiring board of two separation can freely carry out spatial group and attach together and join.
This separate type wiring board is applied to lamp tube device, is convenient to the light fixture assembling and produces.The lamp tube device that adopts this separate type wiring board is applicable to the T8 fluorescent lighting fixture, because adopting parts such as transparent glass tube, power interface tube, insulation deck outside the T5 trichromatic fluorescent light tube integrates, make lamp tube device contour structure size of the present utility model with common T8 fluorescent tube contour structure size basically identical, can easily the T5 fluorescent tube be replaced to be installed on the existing T8 fluorescent lighting fixture and throw light on.Lamp tube device of the present utility model is installed on when having T8 fluorescent lighting fixture (use Inductive ballast) now, the starter in the former T8 fluorescent lighting fixture need only be taken, and can directly substitute former T8 fluorescent tube and throw light on; Simultaneously, the utility model also can be applicable to other T8 light fixture (using electric ballast or ballast-free), the wiring in the T8 light fixture bulb socket directly need only be connected into power input line during installation and get final product.
Because the utility model has adopted T5 trichromatic fluorescent light tube and electric ballast, compare old-fashioned T8 inductance type fluorescent lamp, light source light-emitting efficiency of the present utility model improves more than 15%, own loss is little, power factor improves can be brought up to more than 0.9, synthesis energy saving is more than 30%, noiselessness, no stroboscopic.
The utility model further utilizes PET aluminized mirror facet reflective film to carry out the reflective design of minute surface, improves the effective rate of utilization of light source more than 40%.Because PET aluminized mirror facet reflective film makes the light of the reflecting surface that light source shines to reflect efficiently, reflectivity can reach 90%, is higher than common diffuse-reflective material far away, can reduce the reflection loss of luminous energy very effectively.Reflecting surface is an arc surface, more can and reflex to a shadow surface of relatively concentrating with the ray-collecting that sends of light source than general plane or inclined-plane, improves the light source effective rate of utilization effectively.The transparent glass tube can be placed the reflective membrane of arc surface easily as its outer cover material, can guarantee the radiation response of light fixture, can play the protection dustproof effect to light fixture again.Tubular structure makes the light fixture outer cover be more convenient for cleaning, keeps lighting effect efficiently.
When lamp tube device of the present utility model was applied to the T8 bracket lamp, the synthesis energy saving effect reached 60-70%, and power is that the utility model lamp tube device of 13W-16W can reach the illuminance that existing T8-40W fluorescent lamp equates, can directly substitute the T8-40W fluorescent lamp.
