Description
Technical Field
The invention relates to the fields of optics, mechanics and electronics, in particular to a manufacturing method of a high-brightness LED light projector.
Technical Field
The LED has the characteristics of energy conservation, high brightness, high speed and short-distance irradiation, and the current illumination application of the LED still uses night advertisements, traffic signs, automobile illumination and the like. Early projectors were numerous, and large-area building light projection has its advantages, but some areas are not well suited for light projection, which causes light pollution to the surrounding environment, and LED's replaced the projector to bring a huge market. When applied to commercial advertisements, the LED has the characteristics of energy conservation, high brightness and variability, is suitable for the requirements of commercial advertisements, and attracts the attention of people through the unique variability. The light emitting efficiency of the white light LED is improved year by year, and the white light LED has better color rendering property than the traditional LEDs such as red light, yellow light, green light and the like, and can be applied to real living environments requiring rich colors, so that the white light LED is expected to enter the indoor and outdoor lighting market in the future. However, the projection lamp using the high-brightness LED as the light source, which is introduced by each family in the market, has a problem that the light intensity value and the irradiation range of the projection lamp cannot reach the illumination effect of the early projection lamp due to the optical design deficiency of the LED light source, so that people can look at the state of replacing the early projection lamp by the LED projection lamp.
Disclosure of Invention
In view of the above problems, the present invention provides a method for manufacturing a high-brightness LED projection lamp, which fundamentally solves the basic requirements of the LED projection lamp for illuminance and illumination range, and makes the light distribution curve conform to the standard of the projection lamp.
Technical scheme of the invention
A plurality of high-brightness LEDs are arranged on a claw-shaped metal substrate, and the claw-shaped metal substrate is arranged in a lamp shell.
In the manufacturing method of the high-brightness LED projection lamp, the claw-shaped metal substrate extends towards one direction of the horizontal direction from one metal substrate and is folded upwards into a plurality of sections, and two sides of each folded section of metal substrate respectively extend outwards and are folded upwards symmetrically.
The claw-shaped metal substrate is formed by extending a rectangular metal substrate from a longer side to one side in the horizontal direction and upwards folding the metal substrate into 4 sections, the angles between the sections are respectively 175 degrees, 163 degrees, 171 degrees and 160 degrees from near to far, two sides of 3 sections of metal substrates folded from far ends are respectively symmetrically outwards extended and upwards folded, and the folded symmetrical included angles are respectively 160 degrees, 160 degrees and 166 degrees from top to bottom.
The manufacturing method of the high-brightness LED projection lamp comprises the steps that a row of 6 high-brightness LEDs sleeved with lenses are uniformly arranged on a rectangular metal substrate, 10, 2 and 1 high-brightness LEDs sleeved with lenses are uniformly arranged on 4 sections of metal substrates extending in the horizontal direction from near to far, and 1, 2 and 2 high-brightness LEDs sleeved with lenses are respectively arranged on the metal substrates folded at two sides of 3 sections of metal substrates folded from far ends from top to bottom.
Principle of the invention
Point light source: whatever the size of the light source itself is negligible compared to the distance between the objects it is illuminating. A point source is not a mathematical point but a physical point, i.e. the light source itself has a certain degree of linearity.
Principle of superposition of light waves: when a certain space is subjected to the simultaneous action of two or more light waves, the total amplitude of the light vibration at the certain space is the linear superposition of complex amplitude vectors of the light waves acting on the certain space independently.
The two independent light sources (two LEDs) are incoherent, i.e. no interference occurs back, and the average intensity of the combined vibrations is equal to the sum of the intensities of the partial vibrations.
Illuminance is a physical quantity that characterizes the degree to which an illuminated surface is illuminated, and for a point light source:
namely: e-
E∝A 2
Alpha is the included angle between the axial direction of the light beam and the normal of the illuminated surface.
The luminous intensity is a physical quantity that characterizes the spatial distribution of the luminous flux emitted by a light source over a range of directions and can be measured by the value of the luminous flux emitted by a point light source in a unit solid angle.
When each LED is assumed to be a point light source, the LED accords with all characteristics of the point light source, light emitted by the LED does not generate interference phenomenon and diffraction phenomenon, and meanwhile, the luminous flux of each LED and the transmittance of the lens are the same. Thus, according to the principle of light superposition and the illuminance formula of the point light source, n LEDs on the illuminated object can be obtainedSuperimposed illuminance at one point of the body
Any two points are taken, and the illuminance of the two points is the same, so that the effect of light uniformity is achieved; for convenient calculation, the ideal condition is adopted, and two special points are taken, namely: the center of one group of light spots and a point half of the included angle of the two groups, ei = Ei +,
the value is obtained by substituting the value: there are only three unknowns in the formula, two of which are related: i and γ, substituting in the formula, and obtaining the angle at which the E value is closest.
When the lamp is placed at a distance of 1.5m from the illuminated object, the illuminated area is 5m x 1.5m, and the light is uniformly applied on the area.
The included angle of the lens is made to be theta,
the following is obtained by a substitution value calculation method: gamma 10 ≈
d＝R tan2γ
Alpha plus beta is not less than 41 degree
At this time, more light exceeded the range of 5m × 1.5; when the illuminance of the edge of the illuminated area is 0.75Ei, the included angle is theta/4.
When α + β =45 °, θ/4=7.5 °
γ≈7°
Let the number of LEDs per surface be ni, if γ i ≥7.5°I i "= 0; if gamma is i ＞15°
I i ′＝0；β 0 ＝16°
Is formed by Ei = Ei +
Can obtain gamma i(i＝1，2，3，4) ≈10°，4.5°，8.5°，2.5°
β i ＝β i-l +2γ i-l
n＝1
The following calculations were performed:
(1)i＝1 β 1 ＝16°
γ ≈ 12 ° 2 γ =24 ° from E0= E0+, dark spots will appear at the edges, taking the maximum allowed value γ ≈ 10 °
(2)i＝2 β 2 ＝36°
By E1= E1+
Substitution to obtain
γ 2 ≈4.5°
(3)i＝3 β 3 ＝45°
By substituting E2= E2+, γ is obtained 3 ≈8.5°
(4)i＝4 β 4 ＝62°
By substituting E3= E3+, gamma is obtained 4 ≈2.5°
Effects of the invention
The invention adopts multi-angle LED irradiation to make the LED projection lamp as the basic requirement of the illuminance and the illumination range of the projection lamp, so that the light distribution curve of the LED projection lamp conforms to the standard of the projection lamp, thereby having better market prospect.
