Abstract

The utility model relates to an LED illuminating lamp which sends out light through a three-dimensional structure. The utility model comprises a carrier, LED units, a lamp base, a lamp cap, a switching power source, an LED front-end circuit, and circuit wires. The carrier is a hollow geometric body enclosed with plates. The LED units are embedded in the outer surface of the carrier. The carrier is provided with circuit wires installed on the inner surface. The switching power supply circuit and the LED front-end circuit are arranged inside the lamp base. All the LED units, configured to be in matrix-style serial and parallel networks, are connected in a low-voltage DC circuit formed by the switching power supply circuit and the LED front-end circuit. When a certain LED unit or some successive or dispersive LEDs are damaged, other LED units can still be normally lighted. Since the carrier is hollow, the utility model facilitates the heat-dissipating of the LED lamp body. The LED illuminating lamp with the three-dimensional structure can evenly send out light in all directions; the light source is of good irradiation effect. Made of high-strength inflaming-retarding polymeric material, the carrier is punching-resistant and falling-resistant, not easy to be broken, and very suitable for outdoor applications.

Description

LED illuminating lamp with the stereochemical structure bright dipping

Technical field

The utility model relates to a kind of illuminating lamp, is specifically related to a kind of LED illuminating lamp with the stereochemical structure bright dipping.

Background technology

Adopt high-brightness LED as light source, be called as current world third generation illuminating product, it has the highly low energy consumption feature of economize on electricity, and under equal illumination candle light (or wattage), its power consumption only is 14%～18% of common bulb; But also have the average life that substantially exceeds existing conventional illuminating lamp, time average life that for example continues to light in the tunnel is more than 4 years; If only light as night-luminescent lamp, in 8～12hr/ days, its time average life can reach more than 10 years.But cause the supply current of low-voltage direct front end circuit excessive in order to be unlikely to because of the too much LED of parallel connection in using usually, have to adopt with row parallel connection again after several LED lamp series connection, yet in the middle of the LED of several series connection,, all will cause the LED of this road series connection all blind as long as any damage is blind! " big candle light " difficulty that is difficult to go beyond that illuminator faced with higher illuminance is made in this current just employing than plurality of LEDs.

The utility model content

The purpose of this utility model is to solve the deficiencies in the prior art, and a kind of LED illuminating lamp of stereochemical structure is provided; Accomplish that simultaneously other LED is not involved and can continue normally to light when some LED or some LED are destroyed.

The technical solution of the utility model is achieved in that the LED illuminating lamp with the stereochemical structure bright dipping comprises carrier, LED individuality, lamp socket, lamp holder, Switching Power Supply, LED front end circuit and circuit connection; The hollow geometrical body of described carrier for surrounding with sheet material; Described LED individuality evenly is embedded in the outer surface of above-mentioned carrier, and the inner surface of carrier is provided with circuit connection; Device switching power circuit and LED front end circuit in the lamp socket; All LED are individual all to be connected in the low-voltage dc circuit of being made up of switching power circuit and LED front end circuit with matrix-style serial, parallel network; Described matrix-style serial, parallel network connect, promptly between the positive and negative output lead-out wire of LED front end circuit, be provided with the vertical line of M bar, the vertical line of above-mentioned M bar is provided with the horizontal line of N bar, on above-mentioned positive and negative lead-out wire and vertical line of M bar and the crossing network that forms of the horizontal line of N bar, have M * N+2M node, between per two vertical nodes, be provided with at least one LED individuality.

LED illuminating lamp with the stereochemical structure bright dipping of the present utility model, described geometrical body is a kind of in the middle of the straightedge cylinder, orthopyramid body of n-shaped hollow, the positive rib truncated cone by the cross section, wherein N 〉=3.

LED illuminating lamp with the stereochemical structure bright dipping of the present utility model, described geometrical body can also be in the spheroid of hollow, the ball-crown body a kind of.

The utility model has the advantages that all the LED individualities on the lamp body that is made of LED and carrier thereof all are connected in the low-voltage DC supply circuit with matrix-style serial, parallel network, thereby when some LED or some LED were destroyed, other LED was not involved and can continue normally to light; Because described carrier is the hollow geometrical body, this had both helped the heat radiation of LED lamp body again, had realized each again to three-dimensional bright dipping equably, and was effective than the unidirectional projection led light source irradiation of plane formula; LED carrier integral body all is to be made by the high-strength anti-flaming macromolecular material in addition, is not afraid of to fall and falls, is difficult for broken, is more suitable for outdoor application.

Description of drawings

Below in conjunction with accompanying drawing the utility model embodiment is described further:

Fig. 1 is the LED illuminating lamp profile schematic diagram of embodiment 1;

Fig. 2 is a LED carrier inside structural representation among Fig. 1;

Fig. 3 is the LED carrier profile schematic diagram of embodiment 2;

Fig. 4 is LED lamp power supply the principle figure.

The specific embodiment

As depicted in figs. 1 and 2, the LED illuminating lamp of stereochemical structure comprises the lamp socket 6 of carrier 1, LED individuality 2, Switching Power Supply 5, LED front end circuit 4 and circuit connection 3 and connection carrier 1 and lamp holder 7.The cross section of the carrier 1 of described LED lamp is the n-shaped hollow straightedge cylinder of N 〉=3, and the straightedge cylinder that its employing high-strength anti-flaming macromolecule sheet material is made and the end face of a same material surround; Described LED individuality 2 evenly is embedded in the outer surface of above-mentioned carrier 1, and the inner surface of carrier 1 is provided with circuit connection 3; Carrier 1 is installed on the base 6; Base 6 is installed on the general screw socket 7.Because LED carrier 1 is a hollow straightedge cylinder, this had both helped the heat radiation of LED individuality 2, had realized each again to three-dimensional bright dipping equably, and was effective than the unidirectional projection led light source irradiation of plane formula.

As shown in Figure 3, with the LED illuminating lamp of stereochemical structure bright dipping, being shaped as of carrier 1 is spherical.In reality was made, the shape of carrier 1 can also be multiple shapes such as conical surface body, spherical surface body, regular polygon.Because carrier 1 is to be made by high-intensity flame retarded polymeric material, be not afraid of to fall and fall, be difficult for broken, be very suitable for outdoor application.

As shown in Figure 4, all LED individual 2 all are connected in the low-voltage DC supply circuit that is made of known technology Switching Power Supply 5 and LED front end circuit 4 with matrix-style serial, parallel network; Described matrix-style serial, parallel network connection are meant between LED front end circuit 4 positive and negative lead-out wires and are provided with the vertical line of M bar, the vertical line of above-mentioned M bar is provided with the horizontal line of N bar, on above-mentioned positive and negative lead-out wire and vertical line of M bar and the crossing network that forms of the horizontal line of N bar, have M * N+2M node, between per two vertical nodes: locate to be provided with a LED individuality 2 as aa, ba, ca, Ma etc.When some LED individual 2 or some continuously or the LED that disperses when being destroyed, individual 2 luminous all can not involved of other LED and can continue normally to light.

In sum: this stereochemical structure, adopt network matrix to connect the LED illuminating lamp of power supply, in fact found and developed the unique technique of a kind of " big candle light " LED illuminating product.
