Abstract

A kind of LED lens module, it comprises bearing, lens, LED chip and sealing, LED chip is installed in bearing, lens cap, on this bearing, is encapsulated in LED chip in lens and bearing with sealing, it is characterized in that, this bearing lower inner is arc concave bottom, be provided with a heat dissipation metal frame in these arc concave bottom central authorities, and LED chip is arranged on this heat dissipation metal frame central authorities, and this arc concave bottom surface applies reflecting coating; This heat dissipation metal frame comprises circular top plate and radiating fin, and this radiating fin is connected to circular top plate below and reaches bearing outside.The rest base that the utility model adopts has arc groove, can on this arc groove, apply luminescent coating, and this reflecting coating can, by the light emission of bottom to lens, reduce the light loss of chip light emitting; In addition, the heat dissipation metal frame of employing extends to bearing outside, can effectively conduct heat to the external world, improves radiating efficiency.

Description

LED lens module

[technical field]

The utility model relates to a kind of light illumination, relates in particular to LED lens illumination module.

[background technology]

LED, as luminous lighting product, possesses the feature that the life-span is long, light efficiency is good, and LED illumination now is come into operation on a large scale, has replaced gradually traditional incandescent lamp.But the luminous while of LED chip, produces a large amount of heat energy, because heat radiation is difficult for, can affect LED service life.For common LED lens module, with regard to existing, light utilization is not high enough, the bad problem of dispelling the heat.

[summary of the invention]

The utility model has proposed a kind of good heat dissipation effect for above problem, can utilize luminous energy refraction reflection that the LED lens module of light utilization efficiency is provided by full angle.

This LED lens module comprises bearing, lens, LED chip and sealing, LED chip is installed in bearing, lens cap is on this bearing, LED chip is encapsulated in lens and bearing with sealing, it is characterized in that, this bearing lower inner is arc concave bottom, is provided with a heat dissipation metal frame in these arc concave bottom central authorities, and LED chip is arranged on this heat dissipation metal frame central authorities, and this arc concave bottom surface applies reflecting coating.

This heat dissipation metal frame comprises circular top plate and radiating fin, and this radiating fin is connected to circular top plate below and reaches bearing outside.

These lens and bearing fasten by rotary buckle structure, and this bearing comprises arc concave bottom and sidewall, have annular groove, and lens bottom have card end in sidewall upper limb inner side, and this card end snaps onto buckle in annular groove and installs.

On the annular groove of bearing, along the circumferential direction uniform multiple opening, this opening is applicable to card end to be slipped into from top.

The rest base that the utility model adopts has arc groove, can on this arc groove, apply luminescent coating, and this reflecting coating can, by the light emission of bottom to lens, reduce the light loss of chip light emitting; In addition, the heat dissipation metal frame of employing extends to bearing outside, can effectively conduct heat to the external world, improves radiating efficiency.
