200 and second translucent cover 300 effectively filter LED lamp bead sending high energy shortwave blue light, avoid blue light from penetrating eye lens straight
Up to retina, to reach protection eyes.
When LED lamp of the present invention assembles, the first LED light source structure 700 is entered first from the side card insertion of heat sink 100
In shape sliding slot 103, the first translucent cover 200 is also to enter in the first strip-shaped clamp groove 102 from side card insertion, the second LED light source structure 800
From side, card insertion enters in the second bar shaped sliding slot 106, and the second translucent cover 300 enters in the second strip-shaped clamp groove 105 from side card insertion, then
Both ends are sealed by end cap 500 and have the function that limit is fixed.First end cap 500 is unloaded when disassembly, then pulls out institute
Need component.It is attached between LED lamp all parts of the invention by the mode that is connected together, completely without spiral shell
Nail does not use bonding agent yet, and environmentally protective, assembly and disassembly is convenient and efficient, effectively improves production efficiency, reduces production cost, and
Later period disassembly repair and maintenance is simple, and the components such as light-source structure are easily changed, it is ensured that LED lamp facilitates installation easy to maintain and long-term
Normal use.
Further, 100 upper surface of heat sink is fixed with reflector 400, and 400 two sides of the reflector section that extends outwardly out is in
The reflector 401 of arc line shaped, for the reflector 401 on both sides like the wing of expansion, the section of the first translucent cover 200 is in inverted triangle shape
Setting, reflector 401 combine the LED lamp of formation with the first translucent cover 200 like the sea-gull soared to great heights, modern design, outside
It is unique to see, if the combination of a LED lamp is distributed in classroom, ties group on classroom as a group sea-gull and soars to great heights, builds to classroom
Atmosphere.
Moreover, heat sink 100, bar shaped lamp plate 104, reflector 400, reflector 401 are made of heat-conducting metal, heat sink
100 and first the composition of translucent cover 200 can ventilation and heat first light source chamber, the second translucent cover 300 can with the composition of bar shaped lamp plate 104
The second light source chamber of ventilation and heat, heat sink 100 and bar shaped lamp plate 104, reflector 400 and the setting of reflector 401 are integrated into
Type structure, it is thermally conductive uniformly and quickly, heat sink 100 and reflector 401 substantially increase the heat dissipation area of LED lamp, and the first light
Source chamber and second light source chamber be set as can ventilation and heat chamber, using cross-ventilation, the heat that is generated when LED lamp bead is worked
Quick diffusing is gone out, and heat dishoarding effectively reduces light decay, it is ensured that LED lamp bead works normally for a long time, extends making for LED lamp
Use the service life.
In addition, 100 lower end surface of heat sink is equipped with the first LED light source structure 700 for irradiating downward, and the first LED light source knot
The first translucent cover 200 that section is in inverted triangle shape is covered on structure 700, the first translucent cover 200 effectively concentrates LED lamp bead downward
The light of irradiation is diffused into surrounding, avoids local strong light illuminating or the generation of the phenomenon that halation occurs, so that uniform in light emission is soft, and
And 100 both sides of the upper end of heat sink under cover tilts the second LED light source structure 800 irradiated upward, the second LED light source structure
800 upper covers are equipped with the second translucent cover 300, and the first translucent cover 200 and the second translucent cover 300 are made of high light transmission material, and first
Translucent cover 200 and the second translucent cover 300 effectively filter the high energy shortwave blue light of LED lamp bead sending, and blue light is avoided to penetrate eyes crystalline substance
Shape body goes directly retina, to reach protection eyes, and is covered with arc-shaped curved surface in the second LED light source structure 800 and sets
The reflector 401 set, the second LED light source structure 800 are irradiated towards reflector 401, reflector 401 by light reflected illumination downward,
Second LED light source structure 800 is hidden on the upper surface of heat sink 100, is arranged using hidden light-source structure, is passed through reflector
401 reach diffusing reflection effect, realize that free from glare illuminates purpose, the light homogeneous soft irradiated downward.The present invention passes through reflector
The 401 free from glare light reflected are complementary with being formed across the light of the first translucent cover 200 out, so that whole lamp uniform in light emission
Soft, several LED lamps are evenly distributed in classroom, each other light filling, are formed combined type and are blended light, so that entire classroom shines
Brightness is high, and light is highly uniform out, greatly reduces because of student's visual fatigue and eyesight caused by illumination is insufficient, light is uneven
Decline, LED lamp of the invention have built the comfortable academic environment with natural light effect to students, should be widely promoted
And application.
