Description

A kind of optically focused LED illuminating lamp

Technical field

The utility model belongs to LED illuminating lamp field.

Background technology

What traditional light fixture mostly used is osram lamp or fluorescent tube electricity-saving lamp, and this type of bulb cost is low, highly high, is subjected to very much user's welcome and obtains large-area popularizing.It is lower that but this type of bulb converts electric energy to the efficient of luminous energy, uses very expense.For the very high tungsten filament of resistance wire has been adopted in the brightness that reaches regulation, in use the temperatures involved of Chan Shenging the service life of tungsten filament, thereby determined that the service life of incandescent lamp can not be very long, the high temperature that produces in the work to around environment also produced potential safety hazard, accidents such as the fire that causes because of the high temperature of bulb, scald are unequal to lifting more.Contain toxic metals mercury in the fluorescent tube, thereby and fluorescent tube is easily broken causes the mercury volatilization, the person is damaged, also be unfavorable for environmental protection.In addition, above-mentioned light fixture light is all too dispersed, and brightness is not enough.

Summary of the invention

The purpose of this utility model is to provide a kind of optically focused LED illuminating lamp, and light has enough brightness, also can solve the high temperature and the expense electricity of incandescent lamp, and fluorescent lamp is frangible and problem such as not environmental protection.

The utility model is a kind of optically focused LED illuminating lamp, feature is that it comprises joint, be fixed on the joint and the shell of heat conduction, closely contact with shell and the substrate of heat conduction, be arranged at least one great power LED on the substrate, and circuit board and be connected reflection shield on the shell, described joint is bayonet fittings or screw-type joint, described substrate is an aluminium base, comprises change-over circuit on the described circuit board, and described reflection shield inner surface is coated with reflective membrane.

Compare with existing illuminating lamp, the utlity model has the illuminating ray of high brightness, it is low to generate heat during its work simultaneously, and the luminous efficiency height does not have potential safety hazard; Compare with fluorescent lamp, it is durable, can not be easy to fragmentation, and has the feature of environmental protection, can not damage human body.

Description of drawings

Fig. 1 is a schematic appearance of the present utility model;

Fig. 2 is a decomposing schematic representation of the present utility model;

Fig. 3 is a cut-away view of the present utility model.

The specific embodiment

Contrast Fig. 1, Fig. 2 and Fig. 3, the utility model comprises joint 1, shell 2 and reflection shield 3, and shell 2 one ends are fixedly connected on the joint 1, and reflection shield 3 is fixedly connected on the other end of shell 2.Be provided with substrate 4 and circuit board 6 at joint 1 and shell 2 inside, substrate 4 is provided with a plurality of great power LEDs 5, has change-over circuits such as transformation, rectification on the circuit board 6.

Joint 1 is bayonet type or screw-type, can directly be used on the existing general lamp socket, does not need switching device.Shell 2 adopts heat conductivility good metal material to make, surface area is bigger, and substrate 4 lateral edges closely contact with shell 2 inwalls simultaneously, and substrate 4 is made by the good aluminium of thermal conductivity, its heating is easy to conduct to shell 2 by aluminium base 4 when LED5 works, and is distributed by shell 2.Change-over circuit on the circuit board 6 converts civilian High Level AC Voltage to low-voltage DC, uses for LED5, and therefore being equivalent to the utility model can directly use on civilian power supply, has strengthened applicability of the present utility model.On reflection shield 3 inner surfaces, is coated with one deck reflective membrane 31, can makes light-ray condensing, so light seems brighter that illuminating effect is better.
