Abstract

The utility model provides an LED (light-emitting diode) light source fixing structure, which comprises a light source and a fixed plate, wherein the fixing plate is provided with a plurality of protuberant vertical walls, the vertical walls define a groove for containing the light source, and bends of the vertical walls are used for fixing the light source after the light source is arranged in the groove. Furthermore, a plurality of bends of the vertical walls fix the light source, in addition the other vertical walls are kept vertical. Furthermore, four vertical walls are adopted for surrounding the light source, the bends of two opposite vertical walls fix the light source, and the other two vertical walls are kept vertical and play roles of limiting and pressing during repair. According to the structure, the assembling efficiency is improved, the fixing reliability is improved, and the structure for fixing a light source board or a COB (Chip on Board) light source is provided.

Description

A kind of LED light source fixed structure

Technical field

The utility model relates to a kind of fixed structure of LED light source, and particularly the fixing LED light source plate of a kind of bulb lamp of LED for the COB light source, belong to the LED lighting technical field.

Background technology

LED is the abbreviation of light emitting diode, is a kind of solid matter that can convert electrical energy into luminous energy, due to the advantage of its energy-conserving and environment-protective, replaces just gradually at present conventional light source.In the LED lighting technical field, the bare chip technology mainly contains two kinds of forms: a kind of COB technology, another kind are flip chip technology (Flip Chip).COB is chip on board (Chip On Board, COB) abbreviation, the COB light source is exactly that LED chip directly is attached to the integrated area source technology of high light efficiency on the mirror metal substrate of high reflecting rate, this technology has been rejected the support concept, electroless plating, without Reflow Soldering, without the paster operation, therefore operation reduces closely 1/3rd, and cost has also saved 1/3rd.

The electric energy major part consumed due to LED still is converted into heat energy, and the heat that LED sends must well distribute in time, otherwise will affect the service life of LED, so a lot of LED light fixtures, particularly use the light fixture of great power LED as light source, all be designed with radiator, for the heat that makes LED when work can be good at being delivered on radiator, radiator for stretching (punching press) or aluminium profile structure, the general heat of LED that all transmits by middle heat outlet parts, first LED is welded on (or with regard to a COB light source) on aluminium base, then on the heat transfer part (the heat transfer part is fixed on radiator again) in the middle of light source board being fixed to, but the mode of fixed light source plate (or COB light source) mostly adopts screw to fix, some light source board areas are large just needs a lot of screws to fix, the mode of this employing screw fixed light source plate not only compares spended time, and screw may become flexible in transportation or use procedure, less reliable.

The utility model content

The utility model is for above-mentioned technical barrier, for efficiency and the fixing reliability of raising that improves assembling, provides the structure of a kind of fixed light source plate (or COB light source).

Specifically, LED light source fixed structure described in the utility model, comprise light source and fixed head, on fixed head, is provided with the vertical wall of several projections, and vertically wall surrounds into the groove that holds light source, and after light source was placed in groove, vertically light source was fixed in the wall bending.

Further, light source is fixed in the several bendings in described vertical wall, and several vertical walls keep vertically in addition.

Further, the number of described vertical wall is four, holds light source, and light source is fixed in relative two vertical walls bendings, and another two vertical walls keep vertically, plays pressing effect spacing and while reprocessing.

Further, described light source is COB light source or light source board.

Further, described fixed head is that heat sink material is made.

Further, described fixed head punch forming.

LED light source fixed structure described in the utility model, LED lamp radiator for stretching (punching press) or forming aluminium section, when fixed L ED light source board (or COB light source), can replace the fixed form mode usually screwed etc., have the following advantages:

1. simple when this invention is assembled, can realize the mechanization production in enormous quantities, greatly enhance productivity.Than other fixed forms such as screw, save time, it is firm to connect;

2. after this invention was implemented, COB light source (or light source board) had been fixed on the heat transfer part firmly, and contact is not only tight like this, and reliability is high, and thermal conductivity is good.

The accompanying drawing explanation

Fig. 1 is the assembling schematic diagram of the utility model embodiment;

Fig. 2 is that the utility model embodiment installs rear schematic diagram;

Wherein, 1 is that light source, 2 is that fixed head, 20 is vertical wall.

The specific embodiment

Below in conjunction with accompanying drawing, technology contents described in the utility model is carried out to nonrestrictive explanation, purpose is to be convenient to the public better understand.

As shown in Figure 1-2, LED light source fixed structure described in the utility model, comprise light source 1 and fixed head 2, on fixed head 2, be provided with the vertical wall 20 of several projections, vertically wall 20 surrounds into the groove that holds light source 1, and after light source 1 was placed in groove, vertically light source was fixed in wall 20 bendings.In the present embodiment, the number of described vertical wall 20 is four, hold light source 1, two relative vertical walls 20 bendings are fixing by light source 1, and another two vertical walls 20 keep vertically, play pressing effect spacing and while reprocessing, described light source is COB light source or light source board, described fixed head is that heat sink material is made, and has heat sinking function, described fixed head punch forming.

Specifically, as shown in Figure 1, COB light source (or light source board) is installed on the heat transfer part of punching press (stretching) molding structure, the heat transfer part is when moulding, the made vertical wall of 4 projections, first COB light source (or light source board) is put on the heat transfer part, then use special pressing machinery (self-control tool for stitching, then dress mechanically), after automatic press, become appearance as shown in Figure 2, 2 vertical walls are folded on COB light source (or light source board), other 2 vertical walls are not done pressing, play on the one hand position-limiting action, but these 2 vertical walls of pressing (destroyed when 2 walls of front pressing are reprocessed) while needing to reprocess on the other hand, now COB light source (or light source board) has been fixed on the heat transfer part firmly, contact is not only tight like this, reliability is high, thermal conductivity is good, and can realize automation, packaging efficiency is high.

Should be clear and definite be that foregoing is not to the restriction of structure, all with identical or approximate principle; the improvement that described structure is carried out; so comprise shape, the size material of each several part structure, and the replacement of identical functions original paper, all within the utility model technical scheme required for protection.
