Abstract
The utility model provides an LED lamp with reflection membrane, which comprises a base plate and an LED wafer. A circuit layer is arranged on the front surface of the base plate, the LED wafer is connected with the circuit layer through a conducting wire, and a layer of reflection membrane is coated on the circuit layer on the front surface of the base plate. A layer of reflection material is coated on the front surface of the base plate of the LED lamp with reflection membrane, when the light emitted by the LED shoots a lamp shade or a PVD layer which is used for covering the LED wafer, the reflected light shoots once more through the secondary reflection of the reflection material, therefore the loss of the light energy is greatly reduced, and the resources are saved.
Description
Technical field
The utility model relates to a kind of lighting device, the LED lamp of the band reflective membrane that particularly a kind of light loss consumption is little.
Background technology
Energy problem is a pressing problem that is troubling countries in the world, general illumination has accounted for sizable ratio in consume electric power, the last century Mo appearance of white light LEDs attracts showing warm solicitude for of national governments and enterprise, becomes a hot topic in photoelectron, the illuminating engineering sciemtifec and technical sphere.The luminous energy that the incandescent lamp of the luminous energy that one 10～12 watts led light source sends and 35～150 watts sends is suitable, same illuminating effect LED is than conventional light source energy-conservation 80%～90%, and the life-span is long, and stream time is more than 10000 hours, almost Maintenance free.People expect that white light LEDs becomes new lighting source of the 4th generation, reaches energy-conservation green illumination purpose.
See also Fig. 1, the general structure of LED lamp of present band reflective membrane is: be provided with circuit layer on the insulated substrate one side, the LED lamp body of band reflective membrane is fixed on the one side that metal substrate is provided with circuit layer, links to each other with circuit layer by lead; The LED lamp body of band reflective membrane comprises Lamp cup, and uses the LED wafer of epoxy sealing in Lamp cup.The light transmission Lamp cup that the LED wafer sends, around the directive, light has part light by Lamp cup and reflexes to substrate, and the metal substrate color is darker usually, and light is had absorption, causes the part optical energy loss.
The utility model content
For addressing the above problem, the purpose of this utility model is to provide a kind of LED lamp that can reduce the band reflective membrane of light loss.
For achieving the above object, the technical solution of the utility model is:
A kind of LED lamp with reflective membrane comprises substrate and LED wafer, and substrate front side is provided with circuit layer, and the LED wafer links to each other with circuit layer by lead, applies one deck reflective membrane on the described substrate front side circuit layer.
Described reflective membrane is that the height that optical resin is made reflects silver-colored luminescent material.
Described substrate is a metal substrate, and metal substrate is provided with insulating barrier.
Described substrate is an aluminium base.
Described substrate is a ceramic substrate.
Described substrate is a fibre base plate.
Described a plurality of LED wafer is fixed on substrate front side, covers photic zone on it.
Described photic zone is PVC, PU or glass.
Described LED wafer is sealed in the Lamp cup, and Lamp cup is fixed on substrate front side.
Described substrate reverse side is provided with heat sink.
LED lamp substrate front surface coated one deck reflectorized material of band reflective membrane described in the utility model, when light that LED sends is mapped to lampshade or be used to cover on the photic zone of LED wafer, the light that reflects is through the secondary reflection of reflectorized material, penetrate once more, can significantly reduce optical energy loss like this, save the energy.

The specific embodiment
See also Fig. 1, a kind of LED lamp with reflective membrane, comprise aluminium base 1 and LED wafer 2, aluminium base front surface coated insulating barrier 12, insulating barrier is provided with circuit layer 11, and a plurality of LED wafers are fixed on aluminium base 1 front, and link to each other with circuit layer 11 by lead, reflective membrane 4 directly is coated on the circuit layer 11, and this reflective membrane is that the height that optical resin is made reflects silver-colored luminescent material, covers transparent PVC layer 3 on the LED wafer.
Light transmissive materials such as available PU of PVC layer or glass are replaced herein.
For reaching better radiating effect, heat sink can also be installed in the aluminium base back side.
In addition, can also replace the described aluminium base that is coated with insulating layer coating with ceramic substrate or fibre base plate.
When the LED of this band reflective membrane lamp is connected power supply, the LED wafer is luminous, the transparent PVC layer is crossed in the transmission of part light, some light is reflected back toward substrate in addition, owing to apply reflective membrane on the substrate, this part light that is reflected back to substrate again again transmission pass the PVC layer, can significantly reduce optical energy loss like this, save the energy.
The utility model also has another embodiment, a kind of LED lamp with reflective membrane, comprise aluminium base and LED illumination pipe, LED illumination pipe is made up of Lamp cup and the LED wafer that is sealed in the Lamp cup, aluminium base front surface coated insulating barrier, and insulating barrier is provided with circuit layer, LED illumination pipe is fixed on the aluminium base front, and link to each other with circuit layer by lead, reflective membrane is coated on the circuit layer, and this reflective membrane is that the height that optical resin is made reflects silver-colored luminescent material.
