Description

A kind of small-power high-brightness LED lamp

Technical field

The utility model relates to a kind of LED light more particularly to a kind of small-power high-brightness LED lamps, belong to LED illumination device Technical field.

Background technique

As energy-saving and emission-reduction, energy-saving cry are higher and higher, and a series of policies that country releases in due course, LED Lamps and lanterns are since its small power consumption, long service life, luminous efficiency are high, luminous uniform, just increasingly by the favour of every field；From Distinguished on power, LED lamp is divided into high-powered LED lamp and low-power LED lamp, high-powered LED lamp brightness of illumination foot, compare and Speech, low-power LED lamp light emission luminance is less than high-powered LED lamp, but high-powered LED lamp is to the more demanding of heat dissipation, accordingly , structure is also complex, and cost is also higher, how by structure, makes low-power LED lamp that can also issue enough brightness Light reaches the requirement that small power consumption, structure are simple, light emission luminance is sufficient, is current many producers the problem of studying.

Summary of the invention

The utility model proposes a kind of small-power high-brightness LED lamp, to solve above-mentioned ask aiming at the above problem Topic.

In order to solve the above technical problems, a kind of small-power high-brightness LED lamp provided by the utility model, including a small-power LED chip group, a driving, a pedestal and a connection pin, the driving are longitudinal through pedestal, LED chip group position In driving upper end, the connection pin is located at driving lower end, and the pedestal upper end is covered with glass bulb, and makes LED chip group In glass bulb, LED chip group upper end is covered with one layer of multi-angle condenser, covers outside the multi-angle condenser One layer of diffusion layer.

Preferably as the utility model, the multi-angle condenser is the optical collector structure that one is in isosceles trapezoid, and The optical collector structure is made of the first condenser, second condenser lens and third condenser, and the diffusion layer is a diverging lens, and The shape of the diverging lens is identical with the shape of the glass bulb.

Further preferably as the utility model, the angle between first condenser and second condenser lens is 100- 120 °, the angle between the second condenser lens and third condenser is 100-120 °.

The utility model is combined using concentration structure and diffusing structure, low power LED lamp can be made to issue relatively highlighted The light and increase light emitting region of degree, while structure is simple, easy to maintain, manufacturing cost is low.

Detailed description of the invention

Shown in FIG. 1 is the front appearance structure chart of the utility model；

Wherein: 1, LED chip group；2, it drives；3, pedestal；4, pin is connected；5, the first condenser；6, second condenser lens； 7, third condenser；8, diverging lens；9, glass bulb.

Specific embodiment

The utility model is described in more detail with reference to the accompanying drawings and detailed description.

A kind of small-power high-brightness LED lamp, including a low power LED chip group 1,2, one pedestal 3 and one of driving Connect pin 4.

In above structure, driving 2 is longitudinal to run through pedestal 3, and LED chip group 1 is located at 2 upper ends of driving, and connection pin 4, which is located at, to be driven Dynamic 2 lower end, 3 upper end of pedestal is covered with glass bulb 9, and is located at LED chip group 1 in glass bulb 9, meanwhile, in LED core The upper end of piece group 1 is covered with one layer of multi-angle condenser, and one layer of diffusion layer is covered outside multi-angle condenser.

In the present invention, preferred multi-angle condenser be one be in isosceles trapezoid optical collector structure, and this is poly- Mirror structure is made of the first condenser 5, second condenser lens 6 and third condenser 7,

In the present invention, preferred diffusion layer is a diverging lens 8, and the shape of the diverging lens 8 and glass bulb 9 Shape it is identical.

In practical applications, we have found by test, and the angle between the first condenser 5 and second condenser lens 6 is Angle between 100-120 ° and second condenser lens 6 and third condenser 7 is 100-120 °, when, generated spotlight effect More preferably.

In the present invention, the light that low power LED chip group 1 is distributed is via the first condenser 5, second condenser lens 6 and third condenser 7 by light-ray condensing, the light after aggregation is dissipated through diverging lens 8 again, increases light emission luminance and model to reach The effect enclosed.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change It also should be regarded as the protection scope of the utility model into modification.
