Abstract
The utility model discloses an LED down lamp with high luminous efficiency and luminance uniformity. The LED down lamp comprises a metal lamp body, an LED lamp, an aluminum substrate, a side spring and a metal fixing ring, wherein the LED lamp is arranged on the aluminum substrate; the aluminum substrate is mounted in the metal lamp body; the side spring is mounted on the side edge of the metal lamp body; and the metal fixing ring is mounted on the metal lamp body. The LED down lamp is characterized in that reflective paper is stuck on the inner wall of the metal lamp body; a PC (Poly Carbonate) surface cover is arranged on the metal lamp body; and the metal fixing ring is pressed on the PC surface cover. The LED lamp is welded on the aluminum substrate through lead-free solder paste. A heat radiator is arranged on the metal lamp body. A power fixing bracket is arranged on the metal lamp body. The LED down lamp has the advantages of high luminous efficiency and uniform emitted light.
Description
Technical field
The utility model relates to a kind of LED Down lamp, is a kind of high light efficiency, luminous uniform LED Down lamp specifically.
Background technology
At present, LED Down lamp popular on the market exists following defective and deficiency: do secondary bright dipping medium with ground glass, light transmittance is low and easily cracked in transportation; Lamp body inside is without any receiving light, reflective medium, and light utilization efficiency is low, and from light-emitting area to looking the visible light pearl; Lamp body and radiating element are assemblys, have increased to a certain extent thermal contact resistance, the immense pressure of having given hot transport tape; Power supply output line is directly drawn by the hole in the radiator, only is connected by a line between power supply and the lamp body, can not form the location fixed relationship with lamp body, easily wiring is broken in transportation or the process of installing or weares and teares, and has larger potential safety hazard, is inconvenient to safeguard.
Summary of the invention
The purpose of this utility model provides a kind of high light efficiency, luminous uniform LED Down lamp.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of high light efficiency, luminous uniform LED Down lamp, comprise metal lamp body, LED lamp, aluminium base, limit spring and metal retainer ring, the LED lamp is arranged on the aluminium base, aluminium base is installed in the metal lamp body, the limit spring fitting is at the side of metal lamp body, the metal retainer ring is installed on the metal lamp body, it is characterized in that: be pasted with reflective sheeting on the inwall of described metal lamp body.
Described metal lamp body is provided with the PC face shield, and the metal retainer ring is pressed on the PC face shield.
Described LED lamp is welded on the aluminium base by leadless soldering tin paste.
Described metal lamp body is provided with radiator.
Described metal lamp body is provided with the power supply fixed support.
The utility model compared with prior art has following beneficial effect.
The utility model LED Down lamp is done secondary bright dipping medium with the PC material, can effectively prevent lamp body because vibrations cause assembly impaired, has greatly improved light emission rate, and can't see the lamp pearl in light fixture work; The lamp body heat radiation is the integral type design, has reduced the step that lamp body and radiator panel splice grafting touch, and heat is effectively exported; Added a kind of high reflectance reflective sheeting in lamp body inside, the light on effectively lamp body inside not being had to utilize reflects, and exiting surface light is very even, has greatly increased the light efficiency of whole lamp; External power supply and lamp body are the combination assembly relations, easy disassembly, and power supply output line can not receive pullling of external force or wear and tear, light fixture work is fool proof.
Description of drawings
Fig. 1 is the parts decomposition texture schematic diagram of the high light efficiency of the utility model, luminous uniform LED Down lamp.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in Figure 1, the utility model LED Down lamp comprises metal lamp body 1, LED lamp 2, aluminium base 3, limit spring 4 and metal retainer ring 5, the LED lamp is arranged on the aluminium base, aluminium base is installed in the metal lamp body, the limit spring fitting is at the side of metal lamp body, the metal retainer ring is installed on the metal lamp body, is pasted with reflective sheeting 6 on the inwall of metal lamp body.The metal lamp body is provided with PC face shield 7, and the metal retainer ring is pressed on the PC face shield.The LED lamp is welded on the aluminium base by leadless soldering tin paste.The metal lamp body is provided with radiator.The metal lamp body is provided with power supply fixed support 8.The utility model LED Down lamp is done secondary bright dipping medium with the PC material, can effectively prevent lamp body because vibrations cause assembly impaired, has greatly improved light emission rate, and can't see the lamp pearl in light fixture work; The lamp body heat radiation is the integral type design, has reduced the step that lamp body and radiator panel splice grafting touch, and heat is effectively exported; Added a kind of high reflectance reflective sheeting in lamp body inside, the light on effectively lamp body inside not being had to utilize reflects, and exiting surface light is very even, has greatly increased the light efficiency of whole lamp; External power supply and lamp body are the combination assembly relations, easy disassembly, and power supply output line can not receive pullling of external force or wear and tear, light fixture work is fool proof.
