Description
Technical field
The utility model belongs to the LED lighting technical field, relates to a kind of LED fluorescent lamp, the fluorescent lamp that only has single LED that particularly a kind of irradiating angle is large.
Background technology
The LED fluorescent tube can be widely used in family, industry, commercial lighting, is environmental protection and the energy-conserving product that call in the world, can effectively reduce CO
2Discharge capacity.The LED fluorescent tube has that power consumption is low, long service life, high efficiency, high brightness, the advantage such as low in calories, sturdy and durable.
The body of existing LED fluorescent tube mainly comprises aluminium base and light shield, have one on the aluminium base for the mounting plane that LED is installed, mounting plane is that the plane is owing to LED is installed and dispels the heat and need to determine, light shield is connected on the aluminium base and forms the body cavity with aluminium base, give out a large amount of heats owing to LED is luminous, for these heats are in time distributed in the body cavity, general aluminium base can be done greatlyr, in the certain situation of tube diameter size, aluminium base has just taken most of size, the arcwall face of light shield is reduced, add blocking of interface arrangment between aluminium base and the light shield, the irradiating angle of LED fluorescent tube can be above 120 °.
In order to increase LED fluorescent tube irradiating angle, engineers has designed a lot of improvement structures, such as Chinese patent (notification number CN202165868) on March 14th, 2012 disclosed " a kind of LED wide-angle T8 pipe ", it changes the aluminium shell upper into the arch arc shape by the plane, pcb board and LED lamp pearl are installed thereon, because its LED lamp pearl towards three different directions, has therefore increased irradiating angle.Arc shape changes two planes into or some planes consist of arcuate configuration to follow the close patent of this thinking will arch up in addition, being CN201661880U " a kind of LED fluorescent lamp of irradiating angle light " such as China Patent Publication No., is CN201672461U " a kind of lamp housing of LED light fixture of large illuminating angle " such as China Patent Publication No..
Although above-mentioned this structure can enlarge irradiating angle, the expansion of the irradiating angle of being realized towards different direction by a plurality of LED, but single led irradiating angle does not still enlarge, or even reduce to some extent.
Summary of the invention
There are the problems referred to above in the utility model for existing technology, has proposed the large single LED fluorescent lamp of a kind of irradiating angle, and this single LED fluorescent lamp can be realized the expansion of the irradiating angle of single LED, makes whole single LED fluorescent lamp can enlarge irradiating angle.
The purpose of this utility model can realize by following technical proposal: the single LED fluorescent lamp that a kind of irradiating angle is large, comprise that an aluminium seat and that is strip is removably fixed with the strip lampshade on the aluminium seat, the cross section of described lampshade outer surface is arc, be fixed with a strip aluminium base along aluminium seat length direction on the side of the relative lampshade of described aluminium seat, it is characterized in that, the radian of the cross section of described lampshade outer surface is greater than 180 °, described aluminium base upper surface is equipped with some led light sources along self length direction is single, this aluminium base is positioned at the below of lampshade axial line, and the aluminium seating face of aluminium base both sides all forms the reflective surface of inclination, this two reflective surface forms an angle relatively, and described angle is an obtuse angle.
Lampshade can disassemble from the aluminium seat, convenient for maintaining and replacing; The heat transferred aluminium seat that aluminium base can produce led light source, the aluminium seat in air, is avoided excess Temperature with dissipation of heat; Aluminium base and led light source are positioned at the below of lampshade axial line, can increase the radian of the cross section of lampshade outer surface, because the aluminium seating face of aluminium base both sides all forms the reflective surface of inclination, this reflective surface can be that the polishing of aluminium seating face forms, and the angle that two reflective surfaces form is the obtuse angle, therefore the light reflection that is radiated on the reflective surface can be gone back, light is through can penetrating from the lampshade face below the lampshade axial line after the reflection of reflective surface and lampshade, so this fluorescent lamp only needs single led light source just can make lighting angle greater than 180 °.
In the large single LED fluorescent lamp of above-mentioned irradiating angle, the arc radian of described lampshade outer surface cross section is 220 °～240 °.This radian determines the irradiating angle of light, and when radian was too small, the irradiating angle of this LED fluorescent lamp increased DeGrain; When radian is excessive, the light that lampshade partly irradiates near the aluminium seat a little less than.
In the large single LED fluorescent lamp of above-mentioned irradiating angle, described aluminium base upper surface is 5.8mm～7mm to the distance of lampshade axial line.When this distance was excessive, the radiating effect of led light source was poor; Distance is when too small, the light of light through partly penetrating near the aluminium seat from lampshade after the reflective surface reflection a little less than.
In the large single LED fluorescent lamp of above-mentioned irradiating angle, the dual-side that described lampshade and aluminium seated connection touch is along all having a convex edge along the lampshade length direction, the dual-side that described aluminium seat contacts with lampshade is along all offering the draw-in groove that can match with above-mentioned convex edge along aluminium seat length direction, and above-mentioned convex edge is connected in the draw-in groove.Be fixed on the aluminium seat by convex edge and draw-in groove by lampshade, easy accessibility, lampshade can stressedly make dual-side snap in draw-in groove after opening, and also can make the convex edge put draw-in groove under from an end of draw-in groove.
In the large single LED fluorescent lamp of above-mentioned irradiating angle, the lateral middle of described aluminium seat offers groove along aluminium seat length direction, and above-mentioned aluminium base is fixed in the groove by interference fit.Aluminium base is positioned at the lateral middle of aluminium seat, and it is more even that heat is transmitted, and the power that light is penetrated from lampshade is more even; The interference clamping is so that dismounting is convenient.
In the large single LED fluorescent lamp of above-mentioned irradiating angle, described aluminium seat cooperates with lampshade and forms a pipe, and the aluminium seat is hollow structure, offers some bar-shaped troughs along self length direction on the outer circumference surface of aluminium seat.The aluminium seat of hollow can be saved material, reduces cost; Because the aluminium seat plays heat transmission and thermolysis, so the bar-shaped trough on the aluminium seat outer circumference surface can increase the contact area of aluminium seat and extraneous air, the raising heat dispersion.
In the large single LED fluorescent lamp of above-mentioned irradiating angle, described led light source evenly distributes.Make LED fluorescent lamp uniform irradiation.
Compared with prior art, the single LED fluorescent lamp that this irradiating angle is large has following advantage:
1, because the aluminium seating face of aluminium base both sides all forms the reflective surface of inclination, the light reflection that is radiated on the reflective surface can be gone back, light is through can penetrating from the lampshade face below the lampshade axial line after the reflection of reflective surface and lampshade, therefore this fluorescent lamp only needs single led light source just can increase lighting angle, makes angle greater than 180 °.
2, because the led light source of this LED fluorescent lamp is appropriate with the distance of lampshade axial line after being installed on the aluminium base, so both strengthen exposure intensity, and also can not affect thermal diffusivity.
