Description

The LED light-emitting device

Technical field

The utility model relates to a kind of LED application technology, especially LED light-emitting device.

Background technology

Along with the development of semiconductor LED (light emitting diode), in the life that is applied in people more and more widely of LED light-emitting device.Existing LED light-emitting device is combined to form LED lamp band or lamp string to the LED lamp of colors such as red, green and blue usually, makes it luminous to this LED lamp band or lamp statements based on collusion electricity then; Because reasons in structure, these LED lamps are taken to toward sending the light of particular color or glimmering with certain frequency, lack change color and aesthetic feeling, and in luminescence process, this LED lamp band or lamp string luminous intensity differ, and ray cast can cause part ground light intensity height to ground the time, part ground light intensity is low, often can't satisfy user's further requirement; Therefore, be necessary existing LED light-emitting device is improved.

The utility model content

The technical problems to be solved in the utility model provides a kind of LED light-emitting device, and this LED light-emitting device can make the change of LED light and throw even and soft.

In order to solve the problems of the technologies described above, the utility model adopts following technical proposals: this LED light-emitting device comprises a plurality of LED lamps, in order to the fixed head of fixed L ED lamp and in order to decorate the decoration of described LED light-emitting device, on described fixed head, also be provided with controller in order to the brightness of control LED lamp, described LED lamp links to each other with this controller, on the side of described fixed head, also be provided with the LGP of making by transparent material in order to fixing described LED lamp and controller, on the side of the relative side of described LGP, have storage tank with described fixed head, this storage tank and described LED lamp and location of controls is corresponding and in order to ccontaining described LED lamp and controller also are provided with in order to disperse the diamond texture of the light that described LED lamp sent near the edge of LGP on this side; Be connected with the snap ring of being made by transparent material on the side of the opposite side of described LGP, described decoration is fixed in this snap ring.

According to design concept of the present utility model, described LED lamp number is six, these six rounded distributions of LED lamp, and described controller is positioned at the center of six LED lamps of this circular distribution.

According to design concept of the present utility model, described controller comprises three ports, these six LED lamps corresponding three LED lamp groups that form in parallel in twos, that these three LED lamp groups correspond to respectively is red, white and Lan Sanse, and each LED lamp group one end is corresponding respectively to link to each other with a port of described controller, and the other end is set to earth terminal.

According to design concept of the present utility model, described fixed head is made by the PCB material, and described decoration is a zinc alloy material, and the inner surface cloudy surface of described snap ring is handled.

Compared with prior art, the utlity model has following beneficial effect: (1) is because the utility model is provided with the controller in order to the brightness of control LED lamp, under the effect of this controller, the light that the LED lamp is sent can be gradually become stronger light by more weak light, timing with variation, in conjunction with the colorful light that LED sent, the colorful light of the change of coordinating is very attractive in appearance; (2) because the utility model also is provided with LGP, have diamond texture on this LGP, under the effect of this diamond texture, can make behind the divergence of beam of LED lamp and be incident upon on the decoration, can reach the effect of uniformly light-emitting; (3) because the utility model is provided with red, white and blue three LED lamp groups, it between this lamp group relation in parallel, under the effect of controller, light power circulation change between red, white and blue three groups of LED lamp groups that LED is sent, promptly such as red light slowly being lighted then slowly die down or extinguishing, the white lamps group slowly lights and then slowly dies down again or extinguish then, then arrive blue lamp again, so circulation as people's breathing, has timing very much; (4) because decoration of the present utility model is a zinc alloy material, the inner surface of snap ring is handled through cloudy surface, when light that LED sends arrives decoration, it can stop that this light is by this decoration, the light that makes LED only arrives the atmosphere from seeing through the snap ring that cloudy surface handles, thereby forms the soft ring of light.

The specific embodiment

Referring to Fig. 1, Fig. 2 and Fig. 3, the LED light-emitting device comprises LED lamp 1, fixed head 2 and decoration 3 in the utility model; Wherein, LED lamp 1 is fixedly installed on the fixed head 2, on described fixed head 2, also be provided with controller 4, on the side of described fixed head 2, also be provided with LGP 7 in order to fixing described LED lamp 1 and controller 4, be connected with snap ring 8 on the side of these LGP 7 opposite sides, described decoration 3 is fixed in this snap ring 2.

Described LED lamp 1 has a plurality of, its preferred even number, and the utility model is an example to have six LED lamps 1, and the utility model is described; Certainly also can be less than six or more than six; Six LED lamps, 1 rounded distribution among this embodiment, controller 4 is positioned at the center of six LED lamps of this circular distribution.

This LGP 7 is made by transparent material, its with the side of described fixed head 2 relative sides on have storage tank 71, this storage tank 71 is corresponding with described LED lamp 1 and controller 4 positions, and LED lamp 1 and controller 4 are positioned at this storage tank 71, edge near LGP 7 on this side also is provided with diamond texture 72, this diamond texture 72 can make the divergence of beam of LED lamp 1, then is incident upon on decoration 3 objects such as grade, can reach the effect of uniformly light-emitting.

Described snap ring 8 is also made by transparent material, and it is positioned on another side of LGP 7, and the light of described LED lamp 1 projects in the atmosphere through this snap ring after LGP 7 is dispersed; Decoration 3 is positioned at this snap ring 8, and it matches in order to decorate described LED light-emitting device with fixed head 2, snap ring 8 etc.

As shown in Figure 4, this controller 4 comprises three ports, and it mainly in order to the brightness of control LED lamp 1, gradually changes its brightness; Corresponding three the

LED lamp groups

11,12,13 that form in parallel in twos of six LED lamps 1 among the figure, that these three

LED lamp groups

11,12,13 correspond to respectively is red, white and Lan Sanse, these each

LED lamp group

11,12,13 1 ends are corresponding respectively to link to each other with a port of described controller 4, and the other end is set to earth terminal 9.Under the effect of this controller 4, the strong and weak circulation change of LED emitted light light between red, white and blue three groups of

LED lamp groups

11,12,13, promptly red light is slowly lighted then slowly die down or extinguish such as this controller 7, the white lamps group slowly lights and then slowly dies down again or extinguish then, then arrive blue lamp again, so circulation as people's breathing, has timing very much.

In addition, for reducing the manufacturing cost of this LED light-emitting device, fixed head of the present utility model is preferably pcb board; It can certainly be other material manufacturing; Described decoration 3 is a zinc alloy material, certainly also other opaque material; The inner surface cloudy surface of described snap ring 8 is handled; When light that LED sent arrived decoration 3, it can stop that this light passes this decoration 3, and the light that LED is sent can only reach in the atmosphere by snap ring 8, form the beautiful ring of light, and because of handling through cloudy surface on these snap ring 8 surfaces, therefore, through the light of this snap ring 8, change very soft.
