Description
Technical field
The present invention relates to the LED field of light fittings, particularly a kind of LED energy-saving daylight lamp.
Background technology
The daylight light fixture is widely used in people's the life illumination, and the requirement of people's illumination light fixture is also increasingly high.At present, the LED fluorescent lamp with its high cost performance, light efficiency is big, pollution-free and characteristics such as good energy saving enjoy people's favor, the LED fluorescent lamp is replacing the position of conventional fluorescent gradually.But in the energy more and more nervous today, what people paid close attention to more is the light efficiency and the energy-saving effect of lighting, will be key so how the LED energy-saving lamp improves light efficiency with energy-saving effect.Mostly LED energy-saving daylight lamp on the market is round lamp tube now; The effective light transmission area is all below 50%, and the radiator structure imperfection, causes the loss in heating of LED energy-saving lamp bigger; Energy-saving efficiency is low; The whole energy poor effect, and the fluorescent lamp lampshade all adopts glass at present, infringement easily.
Summary of the invention
The objective of the invention is to the glazed area of present LED energy-saving daylight lamp tool existence little; Deficiencies such as radiator structure imperfection provide that a kind of light efficiency is big, good heat dissipation, energy-saving efficiency are high, lampshade is without glass, long service life, LED energy-saving daylight lamp safe in utilization.
Technical scheme of the present invention is:
A kind of LED energy-saving daylight lamp; Comprise the basic shell of heat radiation, lampshade, end cap and circuit substrate, radiating machine casing is provided with lampshade groove and substrate groove, and lampshade is located on the lampshade groove; Circuit substrate is located on the substrate groove; End cap is enclosed within the two ends of basic shell and lampshade, and circuit substrate is provided with LED wick and drive circuit, and the cross section of the transparent surface of lampshade is an oblong.
LED energy-saving daylight lamp of the present invention; The LED wick is luminous by the driving circuit drives on the circuit substrate, and the heat that is produced when luminous is passed to the basic shell of heat radiation by circuit substrate again with on the order wire circuit substrate; As the last thermal component of light fixture, whole hot transmission route is good by the basic shell of heat radiation; The lampshade transparent surface adopts oblong, has bigger glazed area, and the light-emitting area of whole LED energy-saving daylight lamp is more than 60%.
The bottom surface of LED wick according to the invention is full contact with contacting of circuit substrate; The LED wick contacts the way of contact of adopting LED wick and circuit substrate to contact entirely with 2 of circuit substrates through changing in the past; Make the heat that the LED wick is produced when luminous work among the present invention reduce, not only improved luminous efficiency, and the temperature of LED wick is remained on below 40 ℃; The light decay of LED wick is elongated, has prolonged service life.
Be provided with heat-conducting layer between the bottom surface of LED wick of the present invention and the circuit substrate, the heat that produces when purpose is to make the LED wick luminous can pass on the circuit substrate better more timely.
Between circuit substrate of the present invention and the basic shell of heat radiation one deck heat-conducting glue is arranged; The luminous heat that produces of LED wick is at first passed to circuit substrate; But because the circuit substrate area is little; And be in the chamber of basic shell of heat radiation and lampshade formation, can not must be used as the final part of dispelling the heat to be in the basic shell of outer field heat radiation as final thermal component.In order to reach heat-transfer effect better faster, the present invention has established one deck heat-conducting glue between circuit substrate and the basic shell of heat radiation, thus make heat transmission of the present invention from the LED wick to the basic shell of heat radiation, all good fast from inside to outside.Described heat-conducting glue adopts the organic silicon high-temperature heat-conducting glue.
End cap of the present invention is the L type end cap of lengthening, more than the two ends 1cm of lid basic shell of cover and lampshade.Need end cap to seal after the basic shell of lid cover and the lampshade combination and fix at two ends, the L type end cap of the lengthening that the present invention adopts, purpose is to solve that general end cap comes off easily and the problem that causes the accident that contacts of take place easily to dispel the heat basic shell and support brandreth.The L type end cap of lengthening is being inserted in more than the two ends 1cm that covers basic shell of cover and lampshade with the aspect; Consolidation effect to lid basic shell of cover and lampshade is better; And be not easy to come off; On the other hand below the basic shell of lid cover to be inserted in length more, thereby can prevent to cover the basic shell of cover better and support the accident that cause on the brandreth basis.
Lampshade material of the present invention is that described lampshade material is Merlon or the PC polymer resin, particularly Merlon of light transmittance more than 95%, and its diffusivity can reach 99%; Be uniformly dispersed, do not have brilliant point, brightness is high; Ageing-resistant, anti-flammability is good, high printing opacity, free from glare, no shadow can be extruded, but also injection moulding, loss easy to use is low; Have high impact strength, can be fit to the use of LED bulb, fluorescent tube, light-passing board, shell.
LED wick of the present invention has a silica gel photic zone outward, plays the effect of printing opacity and protection LED wick.
The basic shell of heat radiation of the present invention is the good aluminium type base shell of radiating effect.
The invention has the beneficial effects as follows:
1, lampshade transparent surface of the present invention adopts long ellipse, and the glazed area of fluorescent tube is greater than 60%, and light efficiency is big.
2, LED wick of the present invention adopts the full way of contact, and it is little to generate heat, and temperature is less than 40 ℃, and light decay is long, and the life-span is long.
3, the present invention adopts a plurality of conductive structures, makes that the heat transmission is faster, good heat dissipation effect.
4, the present invention adopts and reduces heating, improves radiator structure, increases multiple modes such as light transmittance, has improved power saving rate 15%～20%.
5, the lampshade material is Merlon or PC, is uniformly dispersed, and does not have brilliant point, and brightness is high.
