Specific embodiment

In order to which those skilled in the art is made to more fully understand the technical solution of the utility model, below in conjunction with the accompanying drawings with it is excellent Selecting embodiment, the utility model is described in further detail.

As shown in Figs. 1-3, a kind of LED light module, it is at least one including wiring board 1, on the wiring board 1 LED luminescence units 2, reflective structure 3 and the mask 4 on the reflective structure 3,4 inside of mask include several convex It rises；

The reflective structure 3 include at least one reflector 31, quantity, position and the shape of the reflector 31 with it is described Quantity, position and the shape of LED luminescence units 2 match, and the inner wall of the reflector 31 is provided with net structure 32.

The wiring board 1 realizes that the LED shines for installing the LED luminescence units 2 and the reflective structure 3 Being electrically connected between unit 2 and power supply；The wiring board 1 is internally provided with circuit, and the circuit on one side and the LED shine list Member 2 is electrically connected, and the other end is electrically connected to a power source, you can realizes being electrically connected between the LED luminescence units 2 and power supply.

The LED luminescence units 2 are installed on the wiring board 1, for providing illumination including at least two LED light Pearl 21, ensures the brightness of the LED light module, the quantity of the LED lamp bead 21 in the LED luminescence units 2 is 2,3,4 It is a, 5 or 6, particular number is configured according to the shape of the actual reflective structure 3, in the present embodiment, the LED light The quantity of pearl 21 is 4, and 4 LED lamp beads 21 form the matrix of two row of two rows.

The reflective structure 3 is located on the wiring board 1, including at least one reflector 31, the reflector 31 Quantity, position and shape and quantity, position and the shape of the LED luminescence units 2 match, and the inner wall of the reflector 31 is set Net structure 32 is equipped with, the net structure 32 is distributed in the entire inner wall of the reflector 31, shines for reflecting the LED The light that unit 2 is sent.

In order to reduce the dazzle of the LED light module, and make its uniform in light emission, the surface of the net structure 32 is arc Face, more preferably, the surface of the net structure 32 is free form surface, convenient for breaing up the light that the LED luminescence units 2 are sent, is made It obtains the light that the LED luminescence units 2 are sent to mix in 31 inner homogeneous of reflector, realize uniform light extraction and eliminates the effect of dazzle Fruit.

31 bottom of reflector is rounded or non-circular, is configured with specific reference to actual needs, in the present embodiment, institute It is in non-circular to state the bottom of reflector 31, the present embodiment is not limited to, as long as all LED of the LED luminescence units 2 can be accommodated Lamp bead 21, the LED luminescence units 2 are located at the bottom of the reflector 31, are sent out convenient for collecting the LED luminescence units 2 The light gone out, and the inner wall for passing through reflector 31 reflects away, the bottom of the reflector 31 of the present embodiment is in non-circular, peace The area bigger of the LED luminescence units 2 is filled, more LED lamp beads 21 can be accommodated, ensures the bright of the LED light module Degree.

The top of the reflector 31 is in non-circular so that the lighting area of the LED light module accounts for the LED light For the area of module than bigger, i.e., the lighting area of described LED light module is big, the LED light module it is more attractive.

The mask 4 is located at the light-emitting surface of the reflective structure 3, for the light transmission for sending the LED luminescence units 2 It goes out, in order to enable the light by the mask 4 transmission forms circular light spot, uniform in light emission, if 4 inside of the mask is provided with Dry protrusion, the protrusion rule or irregular distribution, with specific reference to actual conditions, set the protrusion in 4 inside of mask Distribution situation, in the present embodiment, the protrusion is regularly distributed on the inside of the mask 4, ensures the LED luminescence units 2 The light uniform sent forms circular light spot, and eliminates macula lutea, on the other hand, due to being provided with protrusion on the mask, therefore Internal structure can not be observed directly from the mask exterior, ensures the aesthetics of LED light module.

The structure of the protrusion of 4 inside of mask can be identical, can not also be identical, and in the present embodiment, the protrusion is Hemispherical projections, and the diameter of all hemispherical projections is equal.

Herein it should be noted that since the top of the reflector 3 is in non-circular, therefore the LED luminescence units 2 are sent Light after 3 inner wall of reflector reflection, non-round spot, then the protrusion by the inside of mask 4 are formed, by non-round spot Circular light spot is formed, adds the lighting area of LED light module, and ensure that emergent light spot for circular light spot, meets user Big to lighting area and circular light spot demand.

Compared with prior art, the beneficial effects of the utility model are：

LED light module provided by the utility model sets net structure in the inner wall of reflector, ensures LED light mould The brightness of illumination of group, uniform in light emission, and dazzle is eliminated, and pass through the protrusion on reflector and mask so that the LED light The lighting area of module is big, forms circular light spot, and can eliminate macula lutea.

The above is the preferred embodiment of the utility model, it is noted that for the ordinary skill of the art For personnel, on the premise of the utility model principle is not departed from, several improvements and modifications can also be made, these are improved and profit Decorations are also considered as the scope of protection of the utility model.
