Abstract
The utility model provides a kind of LED lens module of high light-emitting rate uniform light distribution, and including substrate, chip, the chip is packaged in by colloid on the substrate, and wiring board is equipped in the substrate, and the colloid is semicircle；Colloid conventional shape generally as the small size LED of indicative function is trapezoidal, this colloid shape is changed to semicircle, on the one hand can promote the positive maximum light extraction light intensity of LED, on the other hand LED can be expanded to use to backlight application field.
Description
Technical field
The utility model belongs to light emitting diode field more particularly to a kind of LED lens mould of high light-emitting rate uniform light distribution
Block.
Background technology
As depicted in figs. 1 and 2, the colloid conventional shape generally as the small size LED of instruction is trapezoidal, and colloid is ladder
The problems of shape is：1) the light extraction light intensity of LED sides just above is less than the light extraction light intensity in other faces；2) all angles of LED
On light extraction light intensity have differences, cause use scope narrow.
Utility model content
In view of this, for overcome the deficiencies in the prior art, the utility model provides a kind of high light-emitting rate uniform light distribution
LED lens module reduces light extraction light intensity of the LED in all angles, rationally promotes the light extraction efficiency of LED.
To achieve these goals, the utility model adopts the following technical solution：
A kind of LED lens module of high light-emitting rate uniform light distribution, including substrate, chip, the chip is encapsulated by colloid
In on the substrate, being equipped with wiring board in the substrate, the colloid is semicircle.
Further, central axes symmetric packages of the chip along the colloid.
Further, the chip is connected by brilliant line with the wiring board.
Further, the colloid is epoxy resin.
Further, the thickness of the colloid is more than the thickness of the substrate.
Further, the width of the substrate is more than the diameter of the colloid.
Further, the colloid is symmetrical arranged along the central axes of the substrate.
The beneficial effects of the utility model are：Colloid conventional shape generally as the small size LED of indicative function is ladder
This colloid shape is changed to semicircle by shape, on the one hand can promote the positive maximum light extraction light intensity of LED, on the other hand can be with
LED is expanded into use to backlight application field.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with the accompanying drawings and implement
Example, the present invention is further described in detail.It should be appreciated that specific embodiment described herein is only explaining this
Utility model is not used to limit the utility model.
As shown in figure 3, a kind of LED lens module of high light-emitting rate uniform light distribution, including substrate 1, chip 2, the chip 2
It is packaged on the substrate 1 by colloid 3, wiring board is equipped in the substrate 1, the colloid 3 is semicircle.
Central axes symmetric packages of the chip 2 along the colloid 3.
The chip 2 is connected by brilliant line 4 with the wiring board.
The colloid 3 is epoxy resin.
The thickness of the colloid 3 is more than the thickness of the substrate 1.
The width of the substrate 1 is more than the diameter of the colloid 3.
The colloid 3 is symmetrical arranged along the central axes of the substrate 1.
As shown in figure 4, colloid 3 for semicircle, can be promoted LED just above side light extraction light intensity, rationally promoted LED light extraction
Efficiency；In addition, reducing light extraction light-intensity differences of the LED in all angles, the LED for being only used for indicative function originally is extended and is used
Range is to backlight application field.
Embodiment described above only expresses the embodiment of the utility model, and description is more specific and detailed, but simultaneously
Cannot the limitation to the utility model patent range therefore be interpreted as.It should be pointed out that the ordinary skill for this field
For personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these belong to this
The protection domain of utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
