Problems solved by technology

However, the switching power supply is large in size and has a narrow operating temperature range. In particular, the maximum operating temperature usually cannot exceed 50°C (military grade is only 60°C), and the reliable operating temperature of LED needs to be below 70°C, which limits the power supply. Installed in the lamp body, even if it can be installed in the lamp body, the power should not be too large (generally no more than 40W), so the common high-power LED lamps above 100W usually use an external switching power supply, which brings troubles to installation and waterproofing. Great inconvenience, not conducive to the promotion of high-power LED lighting

Embodiment 1

[0035] Embodiment 1, a street lamp that can adjust the irradiation angle and brightness arbitrarily, refer to figure 1 : The base frame of the street lamp is a metal panel 1 made of galvanized steel plate, and the surface of the metal panel 1 is provided with a nano surface sintering treatment layer.

[0036] There are ridges 2 on the metal panel 1, and the metal panels 1 on both sides of the ridges 2 form different partitions: there are four ridges 2, which are symmetrically arranged on both sides of the parallel line of the axis of the installation kit; the lamp has five partitions; The metal panels of each partition form an included angle of 100°-170°; LED light sources 3 are installed on the metal panels 1 of each partition, and the metal panels 1 are bent toward the side where no LED light source is installed.

[0037] The structure of the LED light source 3 is: a high-power LED matrix (also called an LED module) composed of high-power LED light sources.

Embodiment 2

[0040] Embodiment 2, with reference to figure 2 : Basically the same as Embodiment 1, but with the following changes: there are two ridges 2 on the metal panel 1, which are symmetrically arranged on both sides of the extension line or parallel line of the axis of the installation kit; the lamp has three partitions.

Embodiment 3

[0041] Embodiment 3, with reference to image 3 : It is basically the same as Embodiment 2, but there are following changes: the positions of two adjacent subregions are staggered, and the two subregions on both sides are staggered several centimeters upwards compared to the middle subregion. The two partitions have only a part of the common boundary (made of ridges); each has a part of its own boundary. Moreover, two high-power LED matrices composed of high-power LED light sources are arranged in each partition.

[0042] In addition to the above embodiments, the present invention can also make any combination.

[0043] Please refer to Figure 4 , the side views of various combination lamps of the present invention. Explained from top to bottom:

[0044] A. A high-power LED matrix composed of four high-power LED light sources is respectively installed on each partition of the metal panel 1;

[0045] B. A high-power LED matrix composed of four high-power LED light sources ...

Abstract

The invention provides a lamp of which the illumination angle and brightness can be adjusted freely. Large power LED light sources are installed in the lamp and electrically connected with an AC power source. The lamp is characterized in that: the base frame of the lamp is a metal panel on which a ridge is arranged; the metal panel parts on the sides of the ridge separately form different subareas and an angle of 100 degrees to 170 degrees is formed between the metal panel parts of the subareas; the metal panel is bended toward a surface where no LED light source is installed; the setting mode of the LED light sources is that: a large power LED matrix consisting of the large power LED light sources is arranged on the metal panel of each subarea; one end of the metal panel is provided with a lamppost installation package which is connected with a lamppost fixedly; and an electric wire connecting the LED light sources with the AC power source is fixedly set by the lamppost installation package. The lamp can meet the requirements of illumination brightness and illuminance of various roads, factories and mines and has the advantages of no investment on expensive pressure-casting dies and greatly saving metal materials, packing materials, energy consumption during manufacture, transportation cost and storage space.

Description

technical field [0001] The invention relates to a lamp, in particular to a lamp which can adjust the irradiation angle and brightness arbitrarily. Background technique [0002] High-power LED (referring to a single LED power not less than 1W) lighting is a revolutionary technology recognized around the world to replace traditional lighting. High-power LED lamps can be used as replacement products for current high-power street lamps and floodlights. However, due to the short application time of this new technology, there are still many technical problems affecting its promotion and application. The more prominent technical difficulties are: the high-power power supply powered by high-voltage mains cannot be integrated with the lamps, and the problem of a large amount of heat generated by the power supply and LED. Existing LED high-power lighting fixtures usually use low-voltage DC power supply. The most common form is to use a regulated switching power supply and then connec...
