Utility model content
The utility model, according to above not enough, provides a kind of LED lamp of alternative conventional u-shaped fluorescent lamp.
The technical solution of the utility model is:
A LED lamp for alternative conventional u-shaped fluorescent lamp, comprising:
Lamp holder;
Housing, connects with lamp holder;
Fin, connects with housing;
The pcb board of LED is installed, is close to fin and installs;
Diffuser, is arranged on outside LED;
PCB control panel, is arranged in housing, input is electrically connected with lamp holder, output is electrically connected with pcb board;
It is characterized in that,
Described fin is made up of many radial rib, the circumferential muscle that is connected with radial rib, and each circumferential muscle is provided with described diffuser and pcb board.
Define good heat dissipation wind channel between many radial rib of the present utility model, improve radiating effect.
In order to easy for installation, described circumferential muscle is provided with the first draw-in groove, the second draw-in groove, and described pcb board is stuck in heat radiation in the first draw-in groove, and diffuser is stuck in the second draw-in groove.
As preferably, described radial rib is provided with the six roots of sensation, and correspondingly, circumferential muscle also has the six roots of sensation.
In order to improve light-emitting area, the bottom of described fin is fixed with lower light source led plate and lower diffuser, and lower diffuser offers passage.
Connecting without electric wire to reach, improving efficiency of assembling, also comprising PCB intermediate plate, described pcb board is electrically connected by welding with PCB intermediate plate, and PCB intermediate plate is also electrically connected with described PCB control panel by welding, and the welding electrical connection said here is the welding without electric wire.
As preferably, described housing offers louvre.
As preferably, described fin is aluminium section bar, and one stretches and makes.
In order to improve radiating effect further, described radial rib is provided with radiating fin.
The utility model has following beneficial effect:
1, heat radiating metal consumption is few, and area of dissipation is large, and whole metallic heat dissipating part is not exposed at lamp body outside, adopts low-cost high-efficiency non-isolated power supply, there is not potential safety hazard, fully demonstrates that LED lamp is energy-conservation, the life-span long, the advantage of high energy efficiency.
2, the axial length by extending fin and diffuser meets the design needs of the LED of different capacity, one set of die can produce the product of multiple model, 2 or 3 molds can be produced 50W(and be equivalent to U-shaped fluorescent lamp 100W) within the product of multiple serial model No., bring great convenience to Design and manufacture technique, metal material is saved greatly.
3, lamp body can be designed to various U-shaped structure (2U/3U/4U/5U), substitutes the U-shaped fluorescent lamp of complete series completely.
Detailed description of the invention
Now by reference to the accompanying drawings the utility model is further described:
