Description

Combined L ED illuminating lamp

Technical Field

The utility model relates to the field of lighting, concretely relates to modular L ED light.

Background

The structure adopted in the traditional illuminating lamp is mainly composed of an L ED lamp 4 and a light reflecting structure as shown in figure 1, wherein the light reflecting structure adopts a paraboloid which is a paraboloidal mirror formed by rotating a parabola 360 degrees along a central axis, the L ED lamp 4 is arranged on the focus of the central axis, and the head of the L ED lamp 4 faces the opening of the light reflecting structure, when the L ED lamp 4 emits light, the light emitted by the L ED lamp 4 is reflected by the paraboloidal mirror and then emitted, and the emitted light is parallel to the central axis because the L ED lamp 4 is arranged on the focus.

First, the L ED lamp 4 emits light with the highest intensity perpendicular to the central axis, and the larger the angle between the light and the central axis, the weaker the light intensity, so L ED lamp 4 emits light with the strongest light intensity, and because the light within the angle range cannot irradiate on the parabolic mirror, the part of light is directly irradiated and wasted, and L ED can irradiate on the parabolic mirror, the angle between the light reflected by the parabolic mirror and the central axis is necessarily larger than 60 degrees, therefore, the part of light has low intensity, and the irradiation distance of the light reflected by the parabolic mirror is not long.

Second, L ED lamp 4 emits light with a short distance from a conventional parabolic mirror, and if the intensity of light is to be increased, L ED lamp power and parabolic mirror volume are required to be increased.

Thirdly, in order to increase the illumination intensity, when a plurality of illuminating lamps of the traditional parabolic mirror need to be combined for use, the combined volume is large, and the carrying or the use is inconvenient.

Therefore, in order to solve the above problems, a combined L ED lighting lamp is proposed.

Furthermore, the central axis of the L ED lamp (4) is positioned on the symmetrical plane of the reflector curved structure (2).

Furthermore, the central axis of the L ED lamp (4) is vertical to the central axis of the curved reflector structure (2), and since the L ED lamp 4 emits light rays with the strongest light ray intensity, which form an angle of 0-30 degrees with the central axis, the light rays in the angle range effectively irradiate on the parabolic mirror surface and are emitted along the direction parallel to the central axis.

Second, since the curved mirror surface solution structure is a curved surface formed by rotating the curved mirror surface structure about the central axis of the parabola by 60 degrees, the curved mirror surface structure is placed in a housing, and the volume of the housing with the curved mirror surface structure is far smaller than that of the housing with the parabolic mirror under the same illumination intensity. Therefore, the volume of a plurality of housings which are arranged side by side and are provided with the curved surface structures of the reflectors of the invention is far smaller than that of a plurality of housings provided with the parabolic mirrors. The process steps and the cost can be effectively reduced.

Thirdly, the reflector can effectively refract the dissipated light of the L ED lamp to the curved surface structure of the reflector and reflect the light out through the curved surface structure of the reflector, thereby improving the utilization efficiency of the dissipated light.

Fourth, a secondary condenser lens is mounted on the L ED lamp to reduce the angle of emission of light from the L ED lamp by refraction, thereby reducing stray light.
