New description: [New technical field] This creation relates to a lighting fixture, especially a lighting fixture that uses a light-emitting diode as a light source and can take into account a wider range of illumination and enhance the uniformity of light intensity distribution. . [Prior Art] Under the policy of increasing global energy conservation issues and the government will ban the white light bulbs in the future, the most ideal way is to use LEDs as light sources and LEDs. (LED) The advantages of high efficiency, energy saving and dimming have gradually formed a trend in the lighting market. Its application in lighting fixtures such as street lamps, car lights, outdoor lighting and situation lighting has become the focus of global attention. The design of the lighting fixture is mainly to assemble the light-emitting diode mold of the flat plate on the lighting fixture, and the illumination effect is achieved by the number of the light-emitting diodes and the brightness of the light-emitting diode. Generally, the light shape of the light-emitting diode is integrally formed, that is, a lens (Lens) is used to directly design a desired light pattern in one optical, and the convenience of assembling Φ is obtained. • However, the shortcoming of the light-shaped one-piece lighting fixture is that it cannot match the environmental changes and the use requirements. It often happens that the light intensity is concentrated under the lighting fixture, the intensity distribution is uneven, or the illumination angle is not enough, so the lighting fixture and lighting The brightness between the appliances is insufficient, the illumination range is small, and more lighting fixtures need to be installed per unit area, which cannot achieve the purpose of saving energy consumption. 3 M391620 [New content] This is the main purpose of providing a lighting fixture that can take into account both the wide illumination and the uniformity of illumination. In order to achieve the above, the lighting fixture of the present invention comprises: a lamp holder and a plurality of light-emitting diodes, the lamp holder is provided with a plurality of lamp chambers, and the bottom of each lamp chamber forms an open end light outlet, and each lamp At least two opposite side walls are provided in the chamber, and a plurality of light emitting diode elements are respectively disposed on the side walls of the two lamp chambers, and are opposite to the light exit opening of the lamp chamber at an oblique angle, and one side wall The illumination angle of each of the upper LED elements is smaller or larger than the illumination angle of each of the LED elements on the other side wall, and the light-emitting diode elements with different illumination angles form different light shapes and complement each other. At the same time, it takes into account the wider range of illumination and enhances the uniformity of the distribution of light intensity. [Embodiment] The features of the present invention can be clearly understood by referring to the detailed description of the drawings and the embodiments. As shown in the first and second figures, the lighting fixture 20 of the present invention includes a lamp holder 21 and a plurality of light-emitting diode elements 22, wherein: - the lamp holder 21 is provided with a plurality of matrix-arranged lamps. In the chamber 211, the bottom of each lamp chamber 211 is formed with an open end of the light exit opening 212, and each of the lamp chambers 211 is provided with at least two opposite side walls 213, 214 which are vacant, and the hollow side walls 213, 214 of each lamp chamber are located. The same axial direction. A plurality of light-emitting diode elements 22 are respectively disposed on the side walls 213 of the two lamp chambers at an oblique angle with respect to the light exit port 212 of the lamp chamber 211, wherein each of the light-emitting diode elements 22 and the light-emitting port 212 is The angle of inclination 0 1 is 35 to 50 4 M391620 degrees, and the illumination angle of each of the light-emitting diode elements 22 on one side wall 213 of the same row of light chambers 211 is smaller or larger than the light-emitting diodes on the other side wall 214. The illumination angle of the element 22 is as shown in the second embodiment. The illumination angle (0 2) of each of the light-emitting diode elements 22 on the one side wall 213 is 85 to 100 degrees (in this embodiment 90 degrees is an example), and the illumination angle (Θ 3) of each of the light-emitting diode elements 22 on the other side wall 214 is 110 to 125 degrees (in this embodiment, 12 degrees - for example); Also, the light-emitting angle (03) of each of the light-emitting diode elements 22 on the one side wall 213 is 120 degrees', and the light-emitting angle (02) of each of the light-emitting diodes 22 on the other side wall 214 is It is 90 degrees. In the implementation of this creation, different light shapes are complemented by different light-emitting diode elements with different illumination angles (for example, 85-100 degrees with 110-125 degrees), as shown in the fourth figure (A). The distribution of the light source formed by the 90-degree LED component is as shown in the figure, the light intensity of the outer side of the light source is strong, and the intensity of the light near the center is weak, and as shown in the fourth figure (B), The light source distribution formed by the light-emitting diode element having an illumination angle of 120 degrees is as shown in the figure. 'The light source distribution has a large illumination angle range, but the light intensity is concentrated below the φ photodiode element, so the two are different. The illuminating angle of the LED phase-inter-matching 'forms the light source distribution as shown in the fifth figure, and can simultaneously take into account the wider illumination range and enhance the uniformity of the light intensity distribution, and by using the two-emitting diode element At a specific tilt angle (0 1 = 35 to 50 degrees), the ratio of the maximum illuminance to the minimum illuminance produced on the object is lower (less than 4:1), and the weight of the illuminated area is 4, which is not only Increase illumination to significantly increase All sentences of the source. Due to the different tilt angles (0 1) of the LED components, a set of tilt illuminance values are included, the tilt illuminance values respectively including a maximum illuminance and a minimum illuminance ' and the maximum illuminance and the minimum are selected from the slant illuminance values. Illumination is less than a 5 M391620 ratio (4:1). As shown in Table 1, the design value after other environmental conditions will be added (for example, a lampshade with a 50-degree tilt on the light source and a surface light source The distance between the objects is 12 meters and the distance between adjacent light sources is 36 meters. Enter the computer and use the software to select the appropriate illuminance value.
