Description

A kind of LED projection lamp

Technical field

This utility model relates to LED field, particularly a kind of LED projection lamp.

Background technology

Projecting lamp is a kind of for projecting a pattern into the device carrying out showing under curtain or other backgrounds, extensively applies In the place such as the life of people or work.Existing projecting lamp typically uses one or several white light source to carry out orthographic projection, this Plant mode not only cost height, power greatly, and high light injury eyes.

The Essential colour can not decomposed again in color is referred to as primary colors, and primary colors can synthesize other color, and other colors But original color can not be restored.The three primary colors that we generally say, i.e. red, green, blue.Three primary colors can blend all of face Color, adds up to white simultaneously.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of LED projection lamp utilizing optical principle.

The technical scheme that the above-mentioned technical problem of this utility model solution is used is as follows:

A kind of LED projection lamp, including a heat sink, three substrates, three LED chip, three to the first support, three the One lens, a pair second supports and second lens, the first support is separately positioned on three substrates by three, and respectively with three Individual first lens are fixed；Second support is arranged on heat sink, and fixes with the second lens；Second lens are arranged on three first The top of lens；LED chip is separately mounted on three substrates, and the first LED chip is arranged on the position that first substrate center is to the left Putting, the second LED chip is arranged on the position at second substrate center, and the 3rd LED chip is arranged on the position that the 3rd substrate center is to the right Put.

As preferably, the second lens include three spherical crowns, and three spherical crowns is equivalently-sized.Have an advantage in that so that three The light beam that individual LED chip sends can obtain identical refraction effect, so that the light beam that three LED chip send can collect It is irradiated to projected position middlely.

As preferably, three the first lens include an ellipsoid respectively, and three the first lens is equivalently-sized.It is excellent Point is, it is possible to the light beam that LED chip sends farthest is irradiated to projected position, thus improves drop shadow effect.

As preferably, first substrate and the 3rd substrate center are about second substrate centrosymmetry.Have an advantage in that, it is possible to more Calculate well the final projected position of the light beam of LED chip.

As preferably, the position of the first LED chip and the 3rd LED chip is about the positional symmetry of the second LED chip.It is excellent Point is, what the light beam improving three LED chip was finally projected to projected position gathers rate.

As preferably, the light beams colors that three LED chip send is the most red, green and blue.Have an advantage in that, The cost utilizing single colored chip is lower, can more preferably ensure the effect of projection simultaneously, and colour generation is softer, does not hinder eyes.

This utility model compared with the existing technology has the following advantages and effect:

1, use three LED chip due to this utility model, there is good drop shadow effect, and by two lens, make The spotlight effect that must project is good.

2, use the LED chip of three unit colors due to this utility model, utilize optical principle, reduce cost, simultaneously Improve and ensure that the effect of projection.

3, use oval-shaped lenses and the structure of spherical lens combination due to this utility model, thus reach optically focused simultaneously Ensure again the effect of certain range of exposures, and then reach preferable drop shadow effect.

4, due to this utility model simple in construction, low cost, there is good practical value.

Detailed description of the invention

Being described in further detail this utility model below in conjunction with embodiment, following example are to this utility model Explanation and this utility model is not limited to following example.

Embodiment 1:

The present embodiment by 1, three substrates of a heat sink, three LED chip, three to 4, three the first lens of the first support 5, a pair second supports 6 and second lens 7 form

Three pairs of the first supports 4 are separately positioned on three substrate two ends, and fix with three the first lens 5 respectively, first Frame 4 is for installing and fixed first lens 5.Three the first lens 5 include an ellipsoid respectively, and three the first lens 5 Equivalently-sized.

Second support 6 is arranged on heat sink 1 two ends, and fixes with the second lens 7, and the second support 6 is used for installing and fixing Second lens 7.

Second lens 7 are arranged on the top of three the first lens 5.Second lens 7 include three spherical crowns 71, and three spherical crowns 71 equivalently-sized.

LED chip is separately mounted on three substrates, and the first LED chip 31 is arranged on the position that first substrate 21 center is to the left Putting, the second LED chip 32 is arranged on the position at second substrate 22 center, and the 3rd LED chip 33 is arranged on the 3rd substrate 23 center Position to the right.

Embodiment 2:

As it is shown in figure 1, the present embodiment is similar to Example 1, it the difference is that only:

1, first substrate 21 and the 3rd substrate 23 center are about second substrate 22 centrosymmetry.
