Abstract

The utility model discloses a high power LED lighting source which comprises a disc-type bracket, anode and cathode bracket terminals connected with both sides of the bracket, and a chip adhered on the bracket; a silica gel lens is mounted on the bracket and covers the chip, the anode and cathode of the chip are correspondingly connected with the anode and cathode bracket terminals on both sides of the bracket by gold wires, and silica gel is coated on the outer surface of the chip and the gold wires. The high power LED lighting source has simple structure, easy mounting and maintenance; besides, the high power chip has five light emitting surfaces, the chip is adhered on the bracket and is connected with the anode and cathode bracket terminals by gold wires approximating to pure gold, and then the chip and gold wires are coated with silica gel with high light transmittance and high refractive index to have protective effect, finally the silica gel lens with high light transmittance and high refractive index is used for focusing, and the silica gel lens can adjust the lighting angle.

Description

High-power LED illuminating light source

Technical field

The utility model relates to electronic applications, and especially the LED indoor and outdoor lighting is specially a kind of high-power LED illuminating light source.

Background technology

At present the 1W high-power LED light source in the application of every field more and more widely, compare with traditional bulb and energy-saving bulb, LED has long service life (life-span was up to 100,000 hours), environmental protection and energy-conservation 70% the advantage that reaches, and has these advantages and the application lighting field of being made up of led light source is also corresponding.

The utility model content

The purpose of this utility model provides a kind of high-power LED illuminating light source, has the better illumination effect.

In order to achieve the above object, the technical scheme that the utility model adopted is:

High-power LED illuminating light source, include the support of plate-like, it is characterized in that: described support both sides are connected with positive and negative support terminals, gummed has wafer on the support, there is rack-mount silica-gel lens to cover on outside the described wafer, the both positive and negative polarity of described wafer all is coated with silica gel by the corresponding connection of positive and negative support terminals of gold thread with described support both sides on described wafer outer surface, the gold thread.

The utility model is simple in structure; be easy to installation and maintenance; five of powerful wafers are luminous; wafer is glued on the support; by approaching pure gold gold thread turning circuit; by the silica gel protected wafer and the gold thread of high transmission rate and high index of refraction, use the silica-gel lens optically focused of high transmission rate and high index of refraction at last again, employed silica-gel lens can be adjusted lighting angle.

Description of drawings

Fig. 1 is the utility model internal structure schematic diagram.

Fig. 2 is the utility model external structure side view.

The specific embodiment

As shown in Figure 1 and Figure 2.High-power LED illuminating light source, include the support 1 of plate-like, support 1 both sides are connected with positive and negative support terminals 2,3, gummed has wafer 4 on the support 1, there is the silica-gel lens 5 that is installed on the support 1 to cover on outside the wafer 4, the both positive and negative polarity of wafer 4 all is coated with silica gel by positive and negative support terminals 2, the 3 corresponding connections of gold thread 6 with support 1 both sides on wafer 4 outer surfaces, the gold thread 6.

In the utility model; at first the elargol of wafer with high thermal conductivity coefficient is glued on the silver-plated support of copper; to be 99.999% gold thread wafer positive and negative be welded on respectively on the positive and negative electrode of support (adds a safety line on every sealing wire with purity; maximum holding circuit); form a complete circuit; joining powder with silica gel and fluorescent material by corresponding proportion promotes brightness and obtains just white, warm white, cold white photochromic; use the silica gel protected wafer and the gold thread of high transmission rate and high index of refraction again, use the silica-gel lens optically focused of high transmission rate and high index of refraction at last.

Claims

1. high-power LED illuminating light source, include the support of plate-like, it is characterized in that: described support both sides are connected with positive and negative support terminals, gummed has wafer on the support, there is rack-mount silica-gel lens to cover on outside the described wafer, the both positive and negative polarity of described wafer all is coated with silica gel by the corresponding connection of positive and negative support terminals of gold thread with described support both sides on described wafer outer surface, the gold thread.
