Description

Thick film package cooling integral LED fluorescent tube
Affiliated technical field
The utility model content belongs to the semiconductor lamp technical field, relates to a kind of energy-efficient integral LED fluorescent tube.
Background technology
White-light emitting pipe (LED) technology has obtained develop rapidly in recent years, and under the identical condition of luminosity, the power consumption of LED fluorescent tube only is the 40%-50% of common fluorescent lamp, and the life-span then is tens times of common fluorescent lamp; Simultaneously again because the firm difficult fragmentation of LED fluorescent tube and do not contain harmful substance such as mercury, environment there is not any pollution, do not contain infrared light and ultraviolet light in the spectrum of LED fluorescent tube, without any radiation pollution, the LED lamp adopts the direct current constant current driven, any stroboscopic can not occur, can effectively avoid visual fatigue, so it has been known as current optimal green illumination light fixture in the world.
The illuminator of present LED fluorescent tube known in this field all adopts the array of being made up of many LED lamp pearls, and the LED lamp is made up of luminescence chip, power supply lead wire, package lens etc. by pearl.Because LED lamp pearl is selected the lead-in wire dongle configuration for use, heat radiation is complete in two wires, and in the course of work, the heat that the LED luminescence chip produces can not effectively distribute, and long-term heat accumulation can reduce the luminous efficiency of LED, makes LED produce quick light decay.In actual engineering is used,, have to adopt reduce the method that LED uses electric current and LED luminous power, so also just reduced light utilization efficiency and the light distribution effect of LED to a great extent in order to reduce the LED temperature.In addition, existing LED fluorescent tube has also that cost is higher, safe insulation is poor, is unfavorable for deficiency such as regular maintenance cleaning.
The utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, so provide a kind of novel structure,, perfect heat-dissipating low, cost with power consumption under the equiluminous low, be easy to install and the regular maintenance cleaning, can with the thick film package cooling integral LED fluorescent tube of the supporting general and good illumination effect of conventional lamp.
Be used to realize that the above-mentioned purpose technical solution is that the utility model designer is by (comprising heat dissipation characteristics to the various factors that influences the LED luminescent properties, thermal conduction characteristic, optical characteristics, the control power supply, factors such as structure) further investigation of being done and on long-term engineering experiment basis and obtain, this LED fluorescent tube is made up of aluminum heat radiation shell which is provided with control circuit board and battery and the lamp luminescence body that is installed on the aluminum heat radiation shell, wherein: said lamp luminescence body has a fastening spliced aluminium base circuit board that is contained in the power-adjustable in the aluminum heat radiation shell, be packaged with the plurality of LEDs luminescence chip at aluminium base circuit board upper surface thick film, above aluminium base circuit board, be packaged with epoxy or silicone lens.
Compared with prior art, the advantage that the utility model had is:
One, employing is encapsulated in (LED can be that chip-scale also can be a surface mounting component) on the aluminium base circuit board with the earlier direct thick film of LED, again the spliced aluminium base of power-adjustable is fastened on the design in the shell-and-tube radiator, the product heat dispersion has been improved more than 2 times, greatly reduce the LED temperature, prolonged the service life of LED, can strengthen the electric current that passes through of single LEDs in the work, increase the LED luminous power, effectively improved the LED light utilization efficiency, and under the same brightness condition, reduced the LED usage quantity, reduced the cost of led light source.It is outer except that having good heat dissipation characteristics that aluminum is made into the shell-and-tube radiator, also have cost of manufacture low, sturdy and durable, can be for convenience detach and characteristics such as be easy to combine with the LED aluminium base, in light weight.
Two, by having the constant current Drive and Control Circuit of temperature-compensating, battery, battery charge-discharge control circuit, emergency lightening control circuits etc. are packaged in the mode in the fluorescent tube shell in the lump, LED is encapsulated, radiator, the control power supply, battery, battery service control, emergency lighting control, lamp holder, the unified design of each parts such as lens, form the integral structure of tubular type led light source, this integral structure has satisfied the specific (special) requirements of led light source, has versatility simultaneously, can be supporting general with conventional lamp, greatly degree has been expanded the engineering range of application of LED illumination.
Three, the led light source plate surface of being made up by plurality of LEDs in the prior art is a graininess, and its floodlight effect is discontinuous, and the graininess on surface also is unfavorable for the regular maintenance cleaning, and safe insulation is poor.The utility model adopts and encapsulate epoxy (or silicon rubber) lens above the aluminium base circuit board of LED, and this lens outer surface is smooth, can finish functions such as printing opacity, luminous intensity distribution, floodlight, even light, focusing and safe insulation, helps the regular maintenance cleaning simultaneously.Because the whole LED fluorescent tube only uses the led light source plate of lens and plurality of LEDs combination to compare, cost can obviously reduce, and light distribution effect improves greatly.
Four, adopt dielectric strength height, high temperature resistant, ageing-resistant engineering plastics to make the lamp holder of lamp tube ends, can be compatible fully with the lamp holder of common fluorescent lamp, install very conveniently, use as safe as a house.

Fig. 1 is the structural representation of a specific embodiment of the utility model.
Fig. 2 overlooks to structural representation for Fig. 1's.
The specific embodiment
Referring to accompanying drawing, thick film package cooling integral LED fluorescent tube described in the utility model partly is made up of with battery 5 and lamp luminescence body etc. aluminum heat radiation shell 3, control circuit board 4, emergency lighting.In the structure shown in Figure 1, illuminator is made up of the spliced aluminium base circuit board 6 of power-adjustable and the plurality of LEDs luminescence chip 2 that display shape row establishes that is that is attached to aluminium base circuit board 6 upper surfaces, aluminium base circuit board 6 fastening being contained in the aluminum heat radiation shell 3 are packaged with epoxy or silicone lens 1 above aluminium base circuit board 6.Be provided with constant current Drive and Control Circuit, battery charge-discharge control circuit and emergency lightening control circuit on the control circuit board 4 with temperature-compensating, they encapsulate in the aluminum heat radiation shell 3 with battery 5, and the required batteries of emergency lighting is selected the ferric phosphate lithium cell that security performance is good, specific energy is high for use.
