Description

A kind of LED lamp

Technical field:

The utility model relates to the universal electric product, specifically is a kind of LED lamp of being made up of 36 SMD LED.

Background technology:

LED is as the novel illumination product, be widely used in every field owing to it has advantages such as high brightness, bright in luster, good stability, long service life, but heating problem seriously and how to dispel the heat be present LED as one of difficult problem that lighting apparatus faced.

Summary of the invention:

For this reason, the purpose of this utility model is to provide a kind of simple in structure, production and assembly convenience, and caloric value is little and the LED modulated structure easily that dispels the heat, this LED lamp adopts multiaspect formula hollow-core construction, increase area of dissipation, effectively avoided heating to concentrate, prolonged the service life of product.

For achieving the above object, the technical solution adopted in the utility model is as follows:

A kind of LED lamp, by base plate, top board and four hollow-core construction bodies that side plate constitutes, be welded with 8 SMD LED that are in series on the described side plate, be welded with 4 SMD LED on the described top board, base plate is provided with the power supply common port, and SMD LED is connected by circuit and base plate power supply common port on the SMD LED on the described side plate and the top board.

SMD LED on described four side plates is connected in parallel.

4 SMD LED on the described top board link together by the mode of two polyphone back two parallel connections.

The utility model is by base plate, top board and four hollow-core construction bodies that side plate constitutes, and side plate and top board are welded with SMD LED, because this inside configuration space is empty, therefore in use, the heat of the luminous generation of SMDLED can too not concentrate in together, thereby increased area of dissipation, can reach better heat radiating effect, thereby prolonged the service life of product.

The specific embodiment:

Core concept of the present utility model is: pass through special structural design, make bottom surface pcb board, top pcb board and four hollow-core construction bodies that the side pcb board constitutes of LED lamp, and make its inside form hollow, the LED lamp is when luminous like this, the heat that is welded on the luminous generation of SMD LED of top board and side plate then can partly be dispersed by intermediate hollow, thereby can too not concentrate in together, and has increased area of dissipation, can reach better heat radiating effect, thereby prolong the service life of product.

Effect for further setting forth the purpose of this utility model and produce by this technical scheme is described in further details the utility model below in conjunction with the drawings and specific embodiments.

As shown in Figure 1, a kind of LED lamp, by top board 1, four side plates 2, base plate 3 is formed, and is a hollow-core construction body that is surrounded by four side plates 2 between top board 1 and the base plate 3 wherein, the lower end of base plate 3 then is connected with supply unit 4.

As shown in Figure 2, Fig. 2 is the front schematic view of the utility model side plate.Its latus inframedium 2 mainly is made of side plate pcb board 201 and 8 SMD LED being welded on the side plate pcb board 201, and four side plates 2 are positioned at four sides of hollow-core construction body here, are connected in parallel.

As shown in Figure 3, Fig. 3 is the front schematic view of the utility model top board.Wherein top board 1 is circular pcb board 101, evenly is welded with 4 SMD LED 102 on the wherein circular pcb board 101, and these 4 SMD LED, two series connection earlier are being connected in parallel then, and whole top board 1 and four side plates 2 are connected in parallel.

As shown in Figure 4, Fig. 4 is the front schematic view of the utility model base plate.Base plate 3 comprises base plate pcb board 301 and through hole 302, wherein forms between base plate pcb board 301 and side plate 2 and the top board 1 to be electrically connected, and is that power input is SMD LED 102 power supplies on top board 1 and the side plate 2 with through hole 302.

In addition, for ease of being this LED power supply, base plate 3 lower ends also are connected with supply unit 4, and this supply unit 4 can be the 12V battery or civil power changes direct current 12V.

More than be explanation, circuit theory of the present utility model be described further below in conjunction with circuit diagram to structural principle of the present utility model.

As shown in Figure 5, Fig. 5 is the utility model circuit theory diagrams.Wherein LED1, LED2, LED3, LED4 are the SMD LED that welds on the top board, and LED1 connects with LED4 with LED2, LED3 here, and then is connected in parallel.LED5 on the side plate, LED6, LED7, LED8 series connection in twos earlier is then in parallel connection; LED9, LED10, LED11, LED12 also are series connection in twos and then in parallel earlier; at last they are together in series; what other several side plates adopted is same connected mode; here top board, side plate are connected in parallel and are connected with base plate by protective resistance R1, R2, R3, R4, R5, and by bottom hole input 12V voltage.

More than a kind of LED lamp provided by the utility model is described in detail, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
