Drawings
Fig. 1 is a schematic view of the present invention.
In the figure: the LED lamp comprises a reflecting cover 1, a light source 2, a driving block 3, a lamp tube 4, a light-transmitting plate 5, a flanging 6, a reflecting plate 7 and a bottom plate 8.
Detailed Description
The invention will be further explained in detail with reference to the drawings and the following detailed description:
a lamp with good heat dissipation performance comprises a reflecting shade 1, a light source 2 and a driving block 3 fixedly connected to the bottom of the reflecting shade 1, wherein the light source 2 is matched and connected with the driving block 3, the reflecting shade 1 comprises a horn-shaped reflecting plate 7 and a bottom plate 8 positioned at one end of the reflecting plate 7 with a small area, and the driving block 3 is positioned on the bottom plate 8; the bottom plate and the reflector 7 are of an integrally formed structure; the light source 2 is an LED lamp strip, the light source 2 is annular, and the light source 2 is attached to the inner side of the reflector 1 and close to the cover opening of the reflector 1; the light source 2 and the reflecting shade 1 are connected by bonding or bolts; a cylindrical lamp barrel 4 matched with the reflector 1 is sleeved at the opening of the reflector 1, a light-transmitting plate 5 is covered on the opening of the reflector 1, the light-transmitting plate 5 is fixedly connected to the inner wall of the lamp barrel 4, the light-transmitting plate 5 is positioned on the end surface of the lamp barrel 4, and a flange 6 turned over towards the outer side of the lamp barrel 4 is fixedly connected to the corresponding end of the lamp barrel 4 at the light-transmitting plate 5; the distance between the outer side wall of the reflector 7 and the inner side wall of the lamp tube 4 at the corresponding position of the light source 2 is at least 3 mm.
Principle of embodiment:
the LED lamp strip has the advantages of small heat productivity and high brightness, is attached to the reflector 7, and when the LED lamp strip generates heat, the heat of the LED lamp strip is transferred to the reflector 7, and the reflector 7 radiates the heat to the air; it should be noted that, in the conventional lamp, the light emitted by the lamp beads is emitted from one point, so as to ensure sufficient brightness, the requirement on the light emitting brightness of the lamp beads is high, meanwhile, the heat of the lamp beads is very concentrated, and the lamp beads are generally arranged at the position of the reflector close to the bottom of the reflector, so that the temperature of the bottom of the reflector is usually obviously higher than that of the other positions of the reflector, and therefore, a radiator needs to be arranged at the bottom of the reflector; and adopt LED lamp area in this application, bright from a line sends, and luminous area is bigger, consequently can reduce to the luminous requirement of each point on the LED lamp area, and the difference in temperature on the reflector reduces greatly, and is corresponding, and LED lamp area dispels the heat through whole reflector panel 7, and heat radiating area is bigger, has increased the radiating efficiency, consequently need not set up the radiator at the bottom of the cover, has increased production efficiency and manufacturing cost, has reduced the pollution in the production.
