Abstract
The utility model provides a light spot-free LED fluorescent lamp tube which comprises a lamp tube body and lamp holders arranged at both ends of the lamp tube body, wherein the lamp tube body comprises a lamp shade and a heat radiator which are mutually buckled; the heat radiator comprises an arc part with a semi-arc-shaped cross section, a straight part used for fixing a PCB (Printed Circuit Board) and two transition parts positioned at the connecting part of the straight part and the arc part; the straight part is downwards depressed to form a groove with two opened ends; the middle part of the straight part is provided with a boss which upwards protrudes out of the plane of the straight part along the overall length of the straight part; and the fluorescent lamp tubes comprise the types of T5, T8 and T10. According to the light spot-free LED fluorescent lamp tube, the straight part of a heat radiator of an original fluorescent lamp tube is sunk by about 2mm, so that after the lamp tube is lighted up, a light spot between a section bar and the lamp shade is eliminated; and the middle part of the straight part is provided with the boss protruding out by 0.2mm, so that the PCB can be more tightly fixed and cannot be loosed.
Description
Technical field
The utility model relates to a kind of LED fluorescent tube, and especially a kind of LED fluorescent tube that does not have hot spot belongs to the LED technical field of lighting fixtures.
Background technology
Full-fledged along with the LED lighting engineering, led light source is replacing conventional light source gradually with the advantage of its energy-conserving and environment-protective, long service life.LED is the semi-conductor electricity light source of environmental type; Light is soft, and spectroscopic pure helps workman's sight protectio and healthy; The LED fluorescent lamp energy-saving is up to more than 80%; Life-span is more than 10 times of common fluorescent tube, almost is non-maintaining, does not have the problem that will often change fluorescent tube, ballast, starter.
The LED fluorescent lamp is all the same on the overall dimensions bore with traditional fluorescent lamp; Length has three kinds of 60cm and 120cm, 150cm; Its power is respectively 10W, 16W and 20W; And 18W traditional fluorescent lamp (Inductive ballast) actual power consumption is about 26W, and 36W traditional fluorescent lamp (Inductive ballast) actual power consumption is about 45W.
Existing LED fluorescent tube, most lampshades that adopt the PC material to process because the problem of heat-radiating substrate design usually can produce hot spot, influence illuminating effect.
The utility model content
The utility model promptly is to the above-mentioned weak point that exists in the above-mentioned LED fluorescent lamp, and a kind of LED fluorescent tube that does not have hot spot is provided.
Specifically; The described no hot spot LED fluorescent tube of the utility model; Comprise lamp tube body and the lamp holder that is installed in the lamp tube body two ends; Lamp tube body comprises the lampshade and the radiator of mutual fastening, and radiator comprises that cross section is two transition parts of the arc sections of semicircular arc, the flat part that is used for fixing pcb board and arc sections and flat part junction, and said flat part is recessed to form the groove of both ends open downwards.
Further, the middle part of described flat part is provided with the boss in the plane, place protruding upward along the flat part total length.
Further, said transition part has and flat part reflective surface at an angle.
Further, said flat part is 2mm to the degree of depth of lower recess.
Further, the height that said boss protrudes from flat part is 0.2mm.
Further, described fluorescent tube comprises T5, T8, T10 type fluorescent tube.
Further, the material of said lampshade is PC.
The described no hot spot LED fluorescent tube of the utility model with the flat part of radiator in original fluorescent tube about 2mm that sunk, has been eliminated the hot spot between section bar and the lampshade behind the lamp tube starting; And be provided with the boss of protrusion 0.2mm in the middle, make and can not become flexible the fixing tightr of pcb board.
Description of drawings
Fig. 1 is the decomposition texture sketch map of the utility model embodiment;
Fig. 2 is the structure for amplifying sketch map of local A among Fig. 1;
Wherein, 1 is that radiator, 2 is that lampshade, 3 is that lamp holder, 11 is that arc sections, 12 is that flat part, 13 is that transition part, 120 is a boss.
The specific embodiment
Below in conjunction with accompanying drawing, the described no hot spot LED fluorescent tube of the utility model to be described, purpose is better to understand described technology contents for the public; Rather than to the restriction of said technology contents; In fact, with identical or approximate principle, to said fluorescent tube; Comprise the improvement that its shape, size, used material are carried out, all within the utility model technical scheme required for protection.
As illustrated in fig. 1 and 2; The described no hot spot LED fluorescent tube of the utility model; Comprise lamp tube body and the lamp holder 3 that is installed in the lamp tube body two ends; Lamp tube body comprises the lampshade 2 and radiator 1 of mutual fastening, and radiator 1 comprises that cross section is two transition parts 13 of the arc sections 11 of semicircular arc, the flat part 12 that is used for fixing pcb board and arc sections 11 and flat part 12 junctions, and said flat part 12 is recessed to form the groove of both ends open downwards.
Further, the middle part of described flat part 12 is provided with the boss 120 in the plane, place protruding upward along the flat part total length, and said transition part 13 has and flat part 12 reflective surface at an angle.
Further, said flat part 12 is 2mm to the degree of depth of lower recess, has eliminated the hot spot between section bar and the lampshade; The height that said boss 120 protrudes from flat part 12 is 0.2mm, can let pcb board tighter, can not become flexible; Described fluorescent tube comprises T5, T8, T10 type fluorescent tube.
The described no hot spot LED fluorescent tube of the utility model, the hot spot behind the lamp tube starting between section bar and PC cover is eliminated, more lets the people pleasing, can be widely used in many middle places such as room, square, office, public place of entertainment.
