Technical Field
[0001] The utility model relates to the technical field of stage lamps, in particular to a high-light-efficiency stage lamp. Background Art
[0002] Stage lights usually use high-power lamp beads to provide clear and bright light. The high-power chips used in high-power lamp beads generate intense heat when working, which will melt the traditional FR4 and other glass epoxy resin substrates and colloid packages. High-power lamp beads cannot directly use the above packaging structure, but need to use heat-resistant substrates and flat-panel packaging structures.

[0019] The present invention is further described in detail below in conjunction with specific implementation methods.
[0020] The first implementation of the stage light is as follows Figure 1 As shown, a plurality of light emitting units 1 are mounted on the front of the main heat-resistant substrate 9, and the plurality of light emitting units 1 are arranged in parallel in a hexagonal shape. Figure 2 As shown, it includes a secondary heat-resistant substrate 2 installed on the front of the main heat-resistant substrate 9, on which a reflective side wall 3 made of metal or ceramic material is fixed; a high-power chip 4 is installed in the area enclosed by the reflective side wall 3, and the high-power chip 4 is electrically connected to the circuit layer of the main heat-resistant substrate 9 through the circuit layer of the secondary heat-resistant substrate 2, and phosphors are provided in front and on the sides of the high-power chip 4. The rated working power of the high-power chip 4 is 5 to 150W. The front end of the reflective side wall 3 surrounds a light outlet 8, and the stage light is provided with a primary optical lens 7 covering the light outlet 8. A limiting groove 6 is provided on the inner side of the front end of the reflective side wall 3, and the primary optical lens 7 is bonded to the bottom of the limiting groove 6. The area enclosed by the reflective side wall 3 is filled with a high-temperature resistant and high-light-transmittance material, such as silicone. After the light-emitting unit 1 is powered on, the fluorescent powder is stimulated to emit light. Since the side-emitted light encounters the reflective side wall 3 and is reflected forward to the light outlet 8, the light originally emitted toward the light outlet 8 passes through the silicone and is emitted through the optical lens 7 again, thereby improving the light extraction efficiency of the light-emitting unit and enhancing its brightness.
[0021] In this embodiment, the main heat-resistant substrate 9 can be a thermoelectric separation copper substrate or a ceramic substrate, and the auxiliary heat-resistant substrate 2 is preferably a ceramic substrate.
[0022] The second implementation method of the stage light is that the main heat-resistant substrate uses a ceramic substrate. This implementation method does not set a secondary heat-resistant substrate, but multiple light-emitting units are directly fixed on the ceramic substrate, and the high-power chip is directly electrically connected to the circuit layer of the main heat-resistant substrate. The rest of the settings are the same as the first implementation method.
[0023] The lens material of the above two embodiments is glass, or other high temperature resistant and high light transmittance materials, such as silicone.
[0024] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
