To sum up, the spotlight of the present embodiment has high-power, low cost, specular removal, easy accessibility, easy access, heat radiation
Ability is good and the feature of length in service life.
The utility model in the specific implementation, can also choose the aspherical of different focal according to the needs of actual light efficiency
Mirror；Also can arrange N number of middle eyeglass between aspherical mirror and planoconvex lens according to the needs of actual light efficiency, middle eyeglass can
To be fixed by lens carrier, if using aspherical mirror as light source one-level light-emitting window, then planoconvex lens goes out light as N+2 level
(when only aspherical mirror and planoconvex lens two-stage eyeglass on light path system, aspherical mirror is as light source one-level light-emitting window, plano-convex for mouth
Mirror is as two grades of light-emitting windows).
Can also be according to the needs of actual light efficiency, the planoconvex lens of selection different-diameter size and focal length is carried out with aspherical mirror
Collocation, the rising angle of aspherical mirror controls at 30 ± 2 ° according to the diameter of planoconvex lens.
Owing to aspherical mirror is fixed on the light-emitting window of light source light receiving device, therefore aspherical mirror is to the distance of COB integrated optical source
It is set in advance on light source light receiving device, based on the light-emitting area of COB integrated optical source, COB integrated optical source and aspherical mirror 3
Distance controlling at 10 ± 2mm.
As shown in Figure 10, the technical parameter data of existing COB integrated optical source spotlight are as follows:
1st, the focusing angular range of spotlight is 15-30 °.
2nd, embodying from light spot illumination, the power invariability of spotlight is when about 280W, and (two grades of light-emitting windows are to projection for 8m distance
Identity distance from), hot spot angle 15 °, center brightness value is 3831Lux；Hot spot angle 30 °, center brightness value is 1505Lux.
As shown in figure 11, the light path heat radiation combination system of the present embodiment is applied to the technical parameter number recording on spotlight
According to as follows:
1st, the focusing angular range of spotlight is 17-40 °.
2nd, embodying from light spot illumination, the power invariability of spotlight is when about 280W, and (two grades of light-emitting windows are to projection for 8m distance
Identity distance from), hot spot angle 17 °, center brightness value is 5010Lux；Hot spot angle 40 °, center brightness value is 1560Lux.
It in conjunction with Figure 10, Figure 11, and is analyzed comparison to data:
1st, the focusing angular range of spotlight of the prior art is at 15-30 °, and the present embodiment is applied to the tune of spotlight
Burnt angular range is at 17-40 °, and the focusing angular range that the utility model can realize is bigger.
2nd, owing to focusing angle is less, corresponding center brightness value is higher, and identical focusing angle, if center brightness value
Higher, then light efficiency is better；Spotlight of the prior art, center brightness value during focusing angle 15 ° is 3831Lux, and this reality
With new application to spotlight, center brightness value during focusing angle 17 ° is 5010Lux, and bigger focusing angle can obtain on the contrary
To bigger center brightness value, therefore light efficiency is more preferable.
Of the present utility model general principle, principal character and of the present utility model advantage have more than been shown and described.One's own profession
Skilled person will appreciate that of industry, the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Principle of the present utility model is simply described, on the premise of without departing from the utility model spirit and scope, the utility model also can
Have various changes and modifications, in the range of these changes and improvements both fall within claimed the utility model.The utility model is wanted
Protection domain is asked to be defined by appending claims and equivalent thereof.
